Background of the Invention

Technical Field

The present invention relates to a resealable beverage container and a method for manufacturing the same. Specifically, and in accordance with one aspect of the present invention, a beverage container (such as an aluminum can) is provided with a cap that is twisted by the consumer to open the can. A cam mechanism converts the twisting or rotational motion of the cap into linear motion, switching the cap to an opening motion, whereby a frangible sealing tab is pressed into the can. Once the can is opened, the cap can be reversed to remove it from the opening. To consume, the consumer can then twist the cap back into its sealed position within the opening.

Background Art

The beverage and can industries are constantly seeking to create cans that are economical to produce and convenient for consumers. Traditionally, beverage cans have had "pull tabs" that consumers grasped by a loop and pulled until the tab was removed from the can. This created a problem: the tab became a disposable waste item, and the consumer was responsible for ensuring proper disposal. Often, consumers failed to properly dispose of the tab, which not only created waste but also posed a safety risk, potentially causing children to swallow it. Furthermore, the edges of the tab were sharp, and if mishandled, they could cut the fingers or hands of the consumer or anyone handling a loose tab. Due to these issues, the industry has adapted the tab's orientation so that it stays on the can after opening, preventing it from being discarded and the consumer from coming into contact with any sharp edges.

The current state of the art features a "fixed" pull tab that is attached to the can lid by a rivet formed in the can lid next to the opening. The opening is formed by a score line, or frangible "kiss cut," that breaks when the consumer pulls on the pull tab. When broken, the score line creates a hinged tab that remains attached to the can lid, but located inside the can.

Beverage cans with fixed pull tabs have the following disadvantages. First, they are not resealable, so once a consumer opens the beverage, the carbonation of the contents decreases, and foreign matter can flow in as the contents are exposed to the surrounding environment. Second, in order to make the rivets used to secure the pull tab to the beverage can lid, the can lid needs to be made of a different material, typically an aluminum alloy that is stronger than the aluminum alloy used in the sides and bottom of the beverage can. In addition, the pull tab itself is usually made of a different alloy than the sides and bottom of the beverage can, which still requires a stronger (and usually heavier) material. Therefore, recycling aluminum beverage cans can be problematic because of the need to separate the different materials. Using three different materials also tends to increase the weight and expense of the finished container.

We need improved beverage containers that are resealable, economical to produce, and “green” in terms of waste avoidance and easy recycling of aluminum cans. We also need an improved method for manufacturing beverage containers that reduces production time, lowers production costs, and improves product performance.

Invention Disclosure

The beverage can has a sidewall and an integrally formed bottom. The top cap includes an integrally formed receptacle comprising a substantially cylindrical sidewall and bottom wall. A score line formed in the bottom wall defines a pull tab, which, when broken, forms an opening for entering the can. The cap fits into the receptacle and has a sidewall with a cam surface. The cam surface cooperates with a locking device on the cylindrical sidewall of the receptacle so that when the cap is twisted or a sufficient number of arcs, or angles of movement, are selected, the cam surface converts the rotational motion into linear motion, driving the cap downward into the insertion hole. As the cap moves downward, a protrusion on the lower surface of the cap collides with the circumference of the score line, thereby pushing the pull tab into the can.

Once opened and the entire can's contents consumed, the cap can be discarded. Alternatively, the cap can be reinstalled into the receptacle, causing the cam surface and locking mechanism to rotate to a sealed position, whereby the can's contents are protected from the surrounding atmosphere. This prevents spills, loss of carbonation, and the ingress of foreign matter into the can.

Preferably, the beverage container is a can, but the same body as described above can be used for other types of beverage containers, including bottles made of various materials, including plastic, paper, metal (such as aluminum), cartons, cups, and glasses. In a particularly preferred embodiment, the beverage container is an aluminum can, and the lid is made of the same aluminum alloy as the can sidewall. The bottle cap is preferably made of a plastic material of sufficient hardness so that the cam surface does not deform during the opening and closing operations.

The bottle cap can be a separate item, sold separately from the beverage container, and reused after washing. Furthermore, the bottle cap can be provided with different features, such as a child's sip cup cap, so that the beverage container can be converted into a child's sip cup. Other items can be designed, including a bottle cap in the shape of a baby bottle "nipple," to convert the beverage container into a baby bottle. In such embodiments, the contents of the beverage container can be infant formula.

Modes for Carrying Out the Invention

Referring to Figures 1 to 12, a beverage container 10 includes a cylindrical sidewall 12, a closed bottom wall 14, and a lid 16 connected to the sidewall 12 at the opposite end of the bottom wall 14, all of which are integrally formed. In the illustrated embodiment, the beverage container is a can, wherein the bottom wall 14 and sidewall 12 are each formed from a single piece of aluminum material using other known processes. The aluminum material is a lightweight aluminum alloy commonly used in the beverage can industry. The lid 16 is preferably made of the same lightweight aluminum alloy and is joined to the upper end of the sidewall using the same known methods. The lid 16 includes a cylindrical receptacle 18 extending downward from the upper wall 17 into the beverage container 10. The receptacle 18 is located near the outer edge or opening of the lid 16, similar to conventional techniques, so that the beverage container 10 can be used for drinking. A bottle cap 20 is placed into the receptacle 18 and locked in the same manner as described in detail below. The cylindrical sidewall 12 of the beverage container 10 preferably tapers at both the upper and lower ends to provide greater structural integrity, particularly for pressurized contents, such as carbonated beverages.

The lid 16 has an outer edge that can be connected to the upper open end of the beverage container side wall 12, using known processes to form a closed shell for containing beverages. The beverages it can contain are not limited to carbonated or non-carbonated beverages, and can also include food and non-edible products. The receptacle 18 is integrally formed with the upper wall 17 of the lid 16 and includes a cylindrical side wall 22 that extends downward into the beverage container 10, and a bottom wall 24. There is a score line 26 on the bottom wall 24 to form an opening or pull-out plate 25 (see Figures 13B, 13e and 13D) that is pressed into the can when the can is opened. In the open position, the pull-out plate 25 remains connected to the bottom wall 24, and the score line 26 does not form a complete circle or ring; there is a hinge 28 (see Figure 5) in the non-scored area of the bottom wall 24.

As shown, the bottle cap 20 is sized to fit substantially within the receptacle 18 and includes a horizontal annular surface 21 located between a cam formed on the bottom surface 38 and the cylindrical sidewall 40 of the bottle cap. In FIG9 , the bottom wall 24 of the receptacle 18 may include a horizontal annular surface 27 located between the receptacle sidewall 22 and the annular score line 26. When in the assembled and "resealed" position shown in FIG13D , the horizontal annular surface 21 of the bottle cap 20 contacts the horizontal annular surface 27 of the bottom surface of the receptacle 18 to effectively reseal the container 10.

Lid 16 has a shallow, elongated, U-shaped recessed area 30, which serves two purposes. First, recessed area 30 acts as a reinforcement, providing greater strength to lid 16. This is particularly advantageous when lid 16 is made from the same aluminum alloy as sidewalls 12 and bottom wall 14 of container 10. Second, recessed area 30 adds a familiar appearance to consumers, who are accustomed to prior art beverage containers that use a pull tab that is first operated in the opening direction and then in the sealing direction (where the hinge tab is positioned after opening).

As shown in Figures 2, 3, and 5, the cylindrical sidewall 22 of the receptacle 18 has a plurality of equally spaced protrusions 32 that lie substantially in the same plane and are integrally formed on the sidewall 22. Figure 5 shows one of the protrusions as an indentation or recess, as Figure 5 illustrates the outer cylindrical sidewall of the receptacle 16, while the other figures illustrate the inner cylindrical sidewall 22 of the receptacle 16. The protrusions 32 cooperate with the cap 20 to open and seal the container 10 as described below.

5-7 , the bottle cap 20 has an upper radially extending rim 34 that serves as a security feature. As shown in FIG1 , before the beverage container 10 is opened, the rim 34 is flush with the flat outer surface 36 of the lid 16 . The rim is integrally formed with the bottle cap 20 and is preferably made of a plastic material. The rim 34 includes a series of frangible score lines 34 a extending radially outward that can break during the can opening operation. The score lines break by driving the rim downward when the bottle cap is twisted or rotated, thereby pushing it downward into the receptacle 18 . Thus, the broken score line on the rim 34 , preferably formed by a cross-section of the rim 34 (formed by a broken score line extending upward at an angle, thereby extending radially outward and radially upward), clearly indicates that the beverage container has been opened.

The bottle cap 20 is preferably formed of a molded plastic material that is sized to fit substantially within the receptacle 18 and includes a camming surface 38 formed on the lower portion or inner end of a substantially cylindrical sidewall 40. The camming surface 38 may include an integrally formed pointed or dotted protrusion 39 that is offset from the central axis of the bottle cap 20 and extends downwardly into the receptacle 18 when the bottle cap 20 is assembled with the receptacle 18. After assembly, the pointed protrusion 39 is positioned immediately above the score line 26. Thus, as the bottle cap 20 moves downward during container opening, the protrusion 39 pierces the container at the beginning of the score line 26 adjacent to the pull tab flap 28 and then gradually expands the rupture along the score line 26 to the end at the opposite end of the pull tab flap 28.

The cam at the bottom surface 38 may also include a pointed or dot-shaped protrusion 42, which is located on the central axis of the bottle cap 20 and extends downward into the insertion hole 18 when the bottle cap 20 is assembled in the insertion hole 18. When assembled, the protrusion will be immediately higher than the above-mentioned X-shaped score line 44, so that when the bottle cap 20 moves downward during the container opening process, the protrusion can pierce the can body at the X-shaped score line 44, thereby releasing the internal pressure through the pointed protrusion 39 and assisting in breaking the score line 26.

The opening operation of the beverage container 10 can be achieved by a cam structure between the insertion hole 18 and the bottle cap 20. In particular, the cylindrical side wall 40 of the bottle cap 20 forms a cam surface 46. The protrusion 32 is assembled on the cam surface 46, so that the consumer can manually twist the bottle cap 20, and the rotational motion of the bottle cap 20 can be converted into linear motion of the bottle cap 20, thereby driving the bottle cap in a downward direction relative to the insertion hole 18. When the bottle cap 20 moves downward, the score line 26 is punctured by the pointed protrusion 39, and then the crack gradually expands along the score line 26 to its end point. In another embodiment, before the pointed protrusion 39 breaks the score line 26, the protrusion 42 may break an optional X-shaped score line 44, thereby releasing internal pressure and assisting the protrusion 39 in breaking the score line 26.

As shown in FIG8 , the bottle cap 20 includes a gripping feature 48 that facilitates gripping by the consumer when preparing to open the beverage container and, as described below, is used to reseal the beverage container after opening. Depending on the cam surface profile and its orientation, the bottle cap can be rotated in one direction, preferably clockwise, to open, then in the opposite direction (counterclockwise) to remove the bottle cap while consuming the beverage, and then, if the consumer has not finished consuming the beverage, returned to the bottle opening direction to reseal the beverage container. FIG9 shows the symmetrical positioning of the three protrusions 32, spaced approximately 120 degrees apart. Each protrusion engages a corresponding cam element. Primarily, in the illustrated embodiment, the sidewall 40 of the bottle cap 20 is configured by forming grooves to form three cam elements 46 a, 46 b, and 46 c. The shape and inclination of the cam elements are designed to enable the bottle cap 20 to be pushed to the open position in no more than a quarter to half a turn, and measured as an arc, this will be no more than 1 to 2 arcs. While three protrusions may be a balance between cost and effectiveness, the number of protrusions and cam elements can be varied.

Referring to Figures 10 and 11, the bottle cap sidewall 40 includes three equally spaced cam elements 46a, 46b, and 46c. Figure 10 shows the cam elements 46a and 46b and the gripping member 48. The bottom surface 47 of the bottle cap 20 includes a protrusion 42, which acts as a piercing element and pierces the X-shaped score line 44. It also includes another protrusion 39, which also serves as a piercing element. This protrusion is designed and shaped so that it strikes the bottom wall 24 inside the receptacle 18, aligned with the score line 26. As the bottle cap 20 is rotated from the unopened position shown in Figure 10, the cam structure converts rotational motion into translational motion, thereby moving the bottle cap inward. As the bottle cap 20 moves inward, the protrusion 39 rotates, preferably until it reaches the position shown in Figure 11, at which point a portion of the bottom wall 24 breaks and is pushed inward to form a pull-out tab 25, which remains hinged to the bottom wall 24 by the score line 26 but does not extend into a complete loop. Protrusion 39 begins at the beginning of score line 26 and travels only 90 degrees. Therefore, it only travels a portion of its total length. What pushes out pull-out plate 25 is a cam on bottom surface 38, which passes through the plane of receptacle 18 in bottom wall 24. Note that the cam on bottom surface 38 extends from horizontal annular surface 21.

Figures 13A-13D illustrate cross-sectional views of the bottle cap moving between open and resealed positions. As shown in Figure 13A , the bottle cap 20 is positioned in the cross-section shown before the beverage container is opened. Thus, the bottom wall 24 of the insertion hole 18, the cylindrical side wall 22 of the insertion hole 18, and the upper horizontal wall 23 form the lid body 16. As shown in Figure 13A , the bottle cap 20 is in the storage position, i.e., before the can is opened, wherein the insertion hole bottom 24 is not punctured, and the contents of the beverage can 10 are airtight for possible long-term storage. The first, unopened position shows the gripping element 48. In this position, the horizontal annular surface 21 of the bottle cap 20 is positioned above the insertion hole bottom wall 24, but the protrusion 39 is close to or slightly contacting the score line 26. Similarly, if a second protrusion 42 is located at the center of the lower end of the bottle cap 20, it can also be positioned close to the score line 44, if not slightly contacting it.

In FIG13B , cap 20 is rotated approximately 90 degrees clockwise. Due to the cam surface, the cap translates downward a distance sufficient for protrusion 39 to pierce score line 26 as the protrusion moves along the inside of the score line. This rupture creates a pull-out flap 25 that pivots downward via hinge 28 formed between the opposite ends of score line 26 and is pushed into the can by the protrusion. The position of the opposite ends of the score line forms a pivot axis for pull-out flap 25.

When the bottle cap is formed and is positioned at the innermost position relative to the jack, the consumer can rotate the cap counterclockwise (preferably by rotating the gripping element 48). As shown in Figure 13C, the bottle cap 20 is separated from the beverage container 10 and can be placed in a pocket by the consumer, or placed in a position that is easy to get, if the consumer chooses not to consume the contents of the beverage container 10. As evidence that the beverage container has been opened, due to the frangible score line fracture, the edge 34 can be angled upwards, thereby the various parts of the edge are now biased in an upward direction. In addition, when rotating counterclockwise, the cam surface 46 and the projection 32 will eventually separate, and the bottle cap 20 can be separated from the beverage container 10 like this.

When the consumer wishes to reseal the beverage container 10, as shown in Figure 13D, the consumer brings the cap 20 into contact with the receptacle 18 by engaging the cam surface 46 with the protrusion 32. Once this occurs, clockwise rotation will translate the cap 20 downward until a seal is formed between the annular surface 27 of the receptacle bottom wall 24 and the annular surface 21 of the cap 20, thereby keeping the contents of the beverage container fresh and protected from contaminants from external sources.

The bottle cap 20 can be removed again to obtain the contents of the beverage container until all the contents are consumed. Since there is no limit to the type of beverage that the container 10 can contain, the most common "canned" beverages include soda, beer, juice, etc. The contents of the container can be food and include edible liquids, gels, powders, etc., which are all within the scope of the present invention.

Cam devices disclosed herein can be used for bottle caps to provide other functions for beverage can 10. For example, a modification of bottle cap 20 can include a channel extending through bottle cap 20, with a drinking utensil formed at the top and outside, such as a children's sip cup, which will allow children to drink from beverage container 10 without overflowing. Alternatively, bottle cap 20 can be used for a baby's nipple for feeding formula milk powder, juice, water or other beverages suitable for infants. When using a drinking utensil, such as a sip cup and a baby bottle nipple, it is still necessary to use bottle cap 20 to open the container, after which a second "cap" can be used to consume the contents. In any case, as long as the container includes a projection on the cylindrical sidewall of the socket, the open cap and drinking utensil can be sold separately from the beverage container.

Although various plastic materials can be used to make the bottle cap 20, other materials can also be used, including ceramics, metals, etc. However, for harder materials, such as these, it may be necessary to place a sealing gasket between the annular surface opposite the socket and the bottle cap to ensure the best sealing effect.

While the embodiment described herein places the socket and cap on the top of the beverage can, the same opening and reseal structure can be provided on the bottom 14 of the beverage container 10. Likewise, a cylindrical can can be used, as can other container shapes, such as oval, rectangular, etc.

The frangible score line 26 at the bottom of the receptacle 18 is preferably circular in shape, with a closed end and an open end. The inner score line (the lighter line) terminates in a curve toward the cylindrical sidewall of the receptacle to prevent the pull-out panel from falling into the container. The outer score line (the darker line) terminates in the circle formed by the inner score line. As described above, the hinge portion of the pull-out panel remains in contact with the lid once broken.

Protrusion 39, described as a piercing element, is designed to engage a single point during rotation of cap 20 to move deeper and radially inwardly along score line 26. Protrusion 39 may also include additional areas to further push tab 25 deeper into the container. A single point can apply greater force to break the tab, but additional areas of engagement in a secondary manner may aid in the opening process.

The protrusions 32 used in the receptacle allow for the use of very shallow receptacles (relative to threaded designs) while still providing positive opening, closing, and sealing of the cap 20. The protrusions 32 also provide positive detents for the open, closed, and removable cap positions. As shown in Figures 10 and 11, each cam element portion 46a, 46b, and 46c includes a ramped portion 50, a lower detent 52, and an upper detent 54. Once assembled, when the cap 20 is in a resealing position, each of the three protrusions 32 is positioned. The detents prevent the cap 20 from becoming disconnected from the receptacle 18 during transport or storage, as well as when recovering from a sealed position. Referring to Figure 11, the protrusions 32 are shown as dashed circles. When the cap 20 is in the unopened position, each protrusion 32 is positioned adjacent to the lower detent 52, as indicated by the dashed circles 32. The detents 52 prevent the cap 20 from rotating to a position where the protrusions 32 disengage from the cam element 46c, for example, if vibration or the like causes the protrusions to escape from the ramped portion 50. Similarly, when the bottle cap 20 is deliberately selected clockwise to open or reseal the beverage container, the protrusion passes through the upper brake 54 and is locked by the interference device between the brake and the protrusion. The upper brake thereby prevents the bottle cap 20 from accidentally exiting the sealed position. Therefore, the bottle cap 20 is restricted in two positions by the brake. The first position can be referred to as a transport fixed position, and the second position can be referred to as a closed position. The distance between the two brakes, measured along the rotation axis of the bottle cap 20, is equivalent to the distance between the resealing surface of the bottle cap 20 and the bottom surface of the socket. The transport fixed brake or the lower brake 52 limits the rotational movement of the bottle cap 20 by the interference between the edge 34 and the flat upper edge of the socket 20, and the interference between the piercing element or protrusion 39 and the socket pull-open plate 25.

When the bottle cap 20 is rotated in the opening direction, for example, in a clockwise direction, the protrusion 32 on the cylindrical sidewall of the insertion hole follows the inclined portion 50 of the cam member 46, which forms a gradual ramp. This causes the rotational motion of the bottle cap 20 to be converted into a linear or translational motion used to drive the bottle cap 20 into the container. This fixes the piercing element 39 to the pull-out plate 25 and provides the force required to break the frangible score line 26. Further rotation of the bottle cap 20 in the opening direction pushes the pull-out plate 25 further into the container until the protrusion 32 reaches the sealing position of the upper stopper 54. Before the closed position, a slightly higher position on the inclined portion 50 of the cam member 46 provides the necessary resistance to keep the bottle cap from retracting.

When the bottle cap 20 is turned in the direction opposite to the opening direction, the projection 32 will follow the same path to its starting position after opening. The projection 32 can pass the transport fixation or lower stop 52 because the fixing edge 34 and the pull-out plate 25 now do not provide any interference between the transport fixation or lower stop 52 and the gap between the cam element 46, so that the bottle cap 20 can be released from the container.

In the embodiment described and illustrated herein, the cam element 46 is configured as a groove having an inclined portion at opposite upper and lower ends, thereby forming the inclined portion of the entire cam element on the cylindrical side wall 40 of the bottle cap 20. It can be formed as a cam element that protrudes from the surface, is integrally formed, or is connected to the bottle cap as a separate part. In addition, although the protrusion 32, as a cam follower, protrudes from the cylindrical side wall of the socket, the socket can be formed with a cam surface, and the cam follower can be formed on the bottle cap 20. The exact size and shape of the cam surface can be selected to correspond to the specific needs of the beverage container. The overall goal is to select a structure that produces a torque that can be operated by the consumer without applying too much force.

The structure described above can be made using a unique manufacturing process that incorporates several known novel, improved, or avoided steps. In a particularly preferred method for manufacturing beverage containers, as shown in the flow chart of FIG14 , a preformed lid is formed using a shell press. Next, simultaneously with or shortly after the socket is formed, a score line is formed at the bottom of the socket in a transfer press. The bottle cap is formed by injection molding or other suitable methods and supplied to the assembly line, where it is inserted into the socket. The cap is then pressed into the socket using three dies spaced apart around the socket to form the protrusions, all oriented around a common plane. The dies are pressed inward against the cylindrical sidewalls of the socket, with the cap acting as a circular mandrel against the internal pressure of the dies, thereby forming a protrusion 32 that extends into the groove of the cam element. The can lid or end is then packaged and shipped to the filler, who can use conventional processing steps to secure the lid to any can or other beverage container.

The above process achieves several cost and environmental advantages over existing manufacturing techniques. First, the can lid does not have to be processed to form a rivet, which is conventionally used to secure the pull tab to the can lid. No rivet is needed because no pull tab is needed. Rivets require the can lid to be made of a stronger and thicker material, usually made from a different aluminum alloy than the sidewall and bottom. In addition, conventional methods would require forming a pull tab, which may require a third different aluminum alloy. Using three different aluminum materials can create recycling problems, while in the present invention, both the can body and the can lid can be made from a single material.

Referring to Figure 15, another variation of the manufacturing process is disclosed. In a first step, a preformed cover body with a preformed socket is prepared using a shell mold press. In the next step, the cover body and socket are oriented and aligned for conversion stamping. A score line is then made at the bottom of the socket during the conversion stamping process. The molded bottle cap is configured to be assembled and inserted into the molded bottle cap. The molded bottle cap is secured to the socket by forming a protrusion 32 in the manner described above, with the bottle cap serving as a mandrel during the protrusion formation process. Next, the lid with the secured bottle cap is packaged and shipped to a filler or other location for conventional filling, sealing, and shipment to the customer. As in the aforementioned manufacturing process, there is no need to form rivets in the cover body, and no pull tabs are required to attach the rivets. Avoiding these steps saves money and makes the final product easier to recycle.

Another embodiment of a beverage container 100 is shown in Figures 18-35 and includes a body having a cylindrical sidewall 102 and opposing axial ends. The schematic diagram of the beverage container (similar to the previous embodiment) shows a typical aluminum can size and shape beverage container in current use, suitable for a variety of beverages, including soft drinks, juice drinks, and beer. The can body differs from the top features of the prior art container, in that the features of the present invention allow for the container 100 to be opened and resealed.

A bottom wall 104 is integrally formed at one axial end of the side wall 102 in a manner known from the art of aluminum can manufacturing (see FIG. 20 ). However, the can body can be made of other materials and have other shapes, depending on style, function, or a combination of both. A lid 106 is attached to the open axial end of the can body, defined by the cylindrical side wall 102. After filling with a beverage, the lid or top is attached to the can in a conventional, known manner. When assembled, the lid 106, bottom wall 104, and cylindrical side wall 102 form a closed interior space.

A receptacle 108 is formed in the lid 106 and includes a cylindrical sidewall 110 and a bottom wall 112. The receptacle 108 is offset from the center so that it is closer to the periphery of the lid 106 to facilitate drinking and pouring after opening. The receptacle 108 also includes a score line 114 that is gently inserted from the periphery of the bottom wall 112 and forms a substantially closed annular, easily foldable area 113. Another score line 116 is located at the center of the bottom wall 112, preferably including two intersecting score lines that form an "X" at the intersection of the two lines at the center of the bottom wall 112. The bottom wall 112 also includes three inclined surfaces 118, 120, and 122, which are equally spaced around the periphery of the bottom wall 112 within the score line 114. A different number of inclined surfaces can be used, but three is most preferred. The inclined surfaces 118, 120, and 122 are integrally formed in the bottom wall 112.

The receptacle 108 also includes three equally spaced protrusions 124, 126, and 128 formed in the sidewall 110. From an internal perspective, such as shown in Figures 22 and 34, the protrusions (such as protrusions 124 and 128) are shown as grooves because the protrusions are formed from the sidewall material. The lid 106 also includes a recessed area 130, which, as in the previous embodiment, can include instructional text to inform consumers how to use the beverage container 100 opening and resealing features.

A bottle cap 132 is placed into the receptacle 108 and includes a cylindrical sidewall 134 and a bottom wall 136. A series of spiral grooves 138, 140, and 142 are provided at equal intervals in the sidewall 134 of the bottle cap 132. When the bottle cap 132 is assembled in the receptacle 108, the grooves 138, 140, and 142 are designed to receive the protrusions 124, 126, and 128 of the receptacle 108, respectively. In this respect, the embodiment of the beverage container 100 is similar to the embodiment of the beverage container 10. When assembled and before the container is opened, the bottle cap is positioned in the receptacle 108, as shown in Figures 30-32.

The cap 132 also has a handle or gripping element 144 at its upper end, allowing the consumer to rotate the cap clockwise or counterclockwise. As in the previous embodiment, the cap has a frangible edge 146 at its upper periphery, which serves as a security feature. If the cap 132 is rotated further into the receptacle 108, the edge will extend upward. The edge 146, along with all other features of the cap 132, is a one-piece structure, preferably made of plastic. Other materials, including ceramics and metals, may also be used within the scope of the present invention.

A pointed protrusion 148 is formed at the center of the bottom surface of the bottle cap 132. When the bottle cap 132 is placed in the insertion hole 108 and before the beverage is opened, the pointed protrusion 148 is located next to or juxtaposed with the center of the bottom surface of the insertion hole 108, and the intersection of the two lines forms the score line 116. When the bottle cap 132 moves linearly downward and further into the insertion hole 108 during the process of opening the beverage can 100, the pointed protrusion 148 pierces the bottom wall 112 of the insertion hole 108.

In order to understand the mode of operation of beverage container 100 embodiment, reference can be made to Figure 25, which is a top view of beverage container before opening. Optionally, instructions on how to use bottle cap 132 are provided in recessed area 130 using embossing, printing or other methods. First, instruct the consumer to turn or rotate bottle cap 132 clockwise to open beverage container. The inclined plane selected and the inclination of the spiral groove can ensure that beverage container 100 can be opened when using the same or similar power to open conventional beverage container (e.g., soda can). This can be accomplished by a rotational motion preferably ranging from 45 to 90 degrees.

After the bottle cap is rotated or turned to the maximum extent allowed, the bottle cap pushes the frangible area into the can, but the frangible area remains connected to the lid body by the lid body portion between the ends of the score line. To later consume the contents of the beverage container 100, the consumer rotates, twists, or turns the bottle cap 132 in the opposite direction until it passes the rotation starting point, placing the protrusions 124, 126, and 128 in the opened areas of the spiral grooves 138, 140, and 142.

At this point, the consumer pulls up on the bottle cap 132 which is pulled upward by the consumer to become separated from the beverage container 100, and the consumer becomes free from the result of the frangible area formed in the lid 106, and the drink is pushed into the container 100. When the consumer has finished drinking, and if the beverage container 100 is not empty, the consumer can reseal or close the opening of the beverage container by pushing the lid 132 back into the receptacle 108 and then turning, twisting or rotating the lid 132 in the same direction until the lid 132 is fully inserted into the receptacle 108, thereby sealing the opening. In the resealed state of the beverage container 100, the contents of the beverage container 100 can remain fresh, carbonated (in a box for carbonated beverages), and spill-proof (when the beverage container is movable, for example, if kept in a backpack, stroller, car drink holder, etc.).

As described in other embodiments herein, the present invention includes an assembled beverage container, with or without contents, having a unique reseal mechanism. The present invention also includes a beverage container subassembly comprising a lid and a resealable cap, which can be further assembled with a beverage container body, such as those commonly used in aluminum cans for various beverages. The present invention also includes a lid that can be used with the lid, or a beverage container that includes a lid so that the beverage container can be purchased without the lid and the cap can be purchased separately and then used with the resulting beverage container with the aforementioned receptacle. In this way, the lid can be reused over and over again. Purchasing the cap separately from the beverage container will have a "green" effect, in that the lid and cap can be washed and reused over and over again, thereby reducing waste.

Referring to Figures 36 and 37, another feature of the present invention is to provide a bottle cap 200 having the above-mentioned functions, including inclined surfaces 202, 204 and 206, and grooves 208, 210 and 212. As with other embodiments, the bottle cap 200 has an end face or bottom wall 214 that protrudes from the inclined surface. A sealing ring 216 is provided on the end face 214 near its periphery. The sealing ring 216 is made of an elastic material different from the material constituting the bottle cap 200, preferably made of a hard plastic material. The material forming the sealing ring 216 can be injected into a mold through a port and formed on the bottle cap 200 at the same time as the bottle cap 200 is injection molded. Alternatively, the sealing ring 216 can be a separate preformed product that can be bonded in place after the bottle cap 200 is removed from the mold.

Any thermoplastic elastomer (TPE) can be used to make the sealing ring 216. The precise selection is a design choice problem because the only requirement is that the material is easy to shape, easily adheres to the material making the bottle cap, and deforms to a certain extent under pressure (in use). If the sealing ring is pre-made and bonded to the bottle cap end face or bottom wall, other materials can be used. However, it is preferred that the sealing ring be molded in situ. For TPE, it is sometimes called thermoplastic rubber and belongs to a class of copolymers or polymer mixtures including thermoplastic and elastic properties. It is particularly suitable for injection molding, which is a preferred way to form the sealing ring 216 on the bottle cap surface.

It should be noted that in FIG38 , there are two bevels, rather than the three bevels shown in other embodiments. While any number of bevels can be used, two or three are more preferred because they can generate an opening force without excessive torque and are easier to manufacture in quantities greater than three. As shown in FIG38 , the bottle cap used in the embodiment of FIG38 has two bevels on the lower end face, whose sizes and positions are compatible with bevels 226 and 228 shown in FIG38 .

The bottle cap 200 operates in the same manner as the previous embodiment, wherein the consumer rotates the bottle cap in one direction to open the container, then rotates the bottle cap in the opposite direction to remove the bottle cap, and then reinserts the bottle cap into the socket and rotates it in the direction of opening the first container until the bottle cap is completely located in the socket. Figure 35 shows the position of the bottle cap 132 fully entering the socket for resealing the container, wherein the bottom wall 136 of the bottle cap 132 rests on the bottom wall 112 of the socket 108, sealingly engaging between the socket and the bottle cap. In this embodiment, the bottle cap 200 includes a sealing ring in this position, with the sealing ring 216 resting on the bottom wall 112 of the socket to improve the sealing relationship between the socket and the bottle cap. A hard surface (i.e., the metal material constituting the socket 108) contacts a relatively soft material (i.e., the elastomeric material constituting the sealing ring 216) to ensure that the contents of the beverage container obtain a better seal. This is particularly useful when it comes to carbonated beverages such as soda and beer.

In the previously described embodiment, the bottle cap has a handle or gripping element 48, as shown in Figures 10, 11, and 13a. Figures 39 and 40 illustrate another embodiment of a gripping element 232, wherein gripping element 232 includes two parallel crossbars 234 and 236 separated by a distance sufficient to apply a lift or grip a lifting element, such as a coin 238 or an object made of a material rigid enough to transfer torque from the consumer's hand to the bottle cap. Obviously, the larger the diameter of the coin or other object, the greater the force required to be transferred to the bottle cap. The beverage container 240 is sold as an assembly comprising the bottle cap 242 and the tool 238 (assuming it is not a coin), a subassembly comprising the bottle cap 244, the bottle cap 242, and the tool 238 (without the container body and sealed contents), or the bottle cap 242 can be sold by itself. For ease of storage and transportation, and to save costs, it is preferably not sold or packaged with the beverage container 240, the bottle cap 242, and/or the lid/cap assembly.

Referring now to FIG. 41 , another aspect of the present invention involves designing the score line defining the pull-out tab to enhance the ability of the score line to be opened or broken. As shown in FIG. 41 , a lid 244 includes an insertion opening 246, which includes a bottom wall 248. Bottom wall 248 includes three inclined surfaces 250, 252, and 254, and a frangible region 256 defined by a score line 258. As described in one of the previous embodiments, score line 258 is annular, rather than completely disposable, so that a hinge is formed between the opposing ends of the score line. Score line 258 is formed during the molding step of lid 244 and, for beverage cans, is made of 0.008-inch thick material. The score line is typically 0.004 inches deep, so for aluminum beverage cans, the thickness of the lid below the score line is typically about 0.004 inches. During the lid molding process, the material thins, and in essence, the material comprising the lid deforms and flows to create the thinned region below the score line.

During the pressing process, the material of the same body flows or deforms, forming a piercing area 260 at one end of score line 258, where a bevel strikes the score line. At the start of the opening process, this bevel pushes against the enlarged piercing area 260, which, for aluminum cans, has already been thinned to essentially the thickness of the beverage container's sidewall. In other words, the entire piercing area is thinned relative to the surrounding surface of the lid, making it easier to puncture or break the score line. Once the score line breaks in the piercing area, the breakage easily and predictably spreads to the surrounding score lines, making it easier to open the beverage container. While piercing area 260 is thinner and therefore more susceptible to accidental opening, it is no thinner than the beverage container's sidewall and can therefore withstand internal pressure. It is also protected from accidental external rupture when positioned in the receptacle.

Each embodiment described herein has been referred to as including a pull-out tab, such as pull-out tab 25, as part of the bottom wall of the receptacle, defined by a circular or annular score line. This pull-out tab is also referred to as a "breakaway region" because it detaches from the rest of the bottom wall when the bottle cap is lowered into the receptacle. While the pull-out tab or breakaway region need not be substantially circular or annular in shape, it is indeed so in the second illustrated embodiment shown in FIG38 . While all other aspects of the beverage cap 218 are identical to the previous embodiments, including a receptacle 220 having a bottom wall 222, the bottom wall has an "S"-shaped score line 224 that breaks when the bottle cap is moved downward and engages with ramps 226 and 228, forming two separate pull-out tabs. During the opening operation, the pull-out tabs are pushed inward, forming two separate pull-out tabs that pass through hinges at opposite ends of the bottom wall 222. During the opening process, a central protrusion in the cap pierces a thin-walled region 230 at the center of the score line. At about the same time, the insert and the bevel of the cap work together to push against the opposite frangible area, which will become the hinge, essentially located at the "loop" portion of the S-shaped score line. At the same time, two pull-out panels are formed, which are pushed into the beverage container.

During the opening and closing operation, it is preferred to turn the handle or gripping element 90 degrees in one direction, then remove the cap from the socket and turn the gripping element 90 degrees in the opposite direction to return to the starting point. To remove the cap and lid simultaneously, the gripping element is turned an additional 10 degrees until the groove and protrusion separate and the cap can be freely lifted upwards and away from the container. Different combinations of embossed and non-embossed bevels, as well as different combinations of different numbers of bevels, can be used to achieve the desired effect. The spacing between the cap and the bottom wall of the socket is equal to the linear motion length when manipulating the cap between the conveying and opening/resealing positions (approximately 0.055 inches for aluminum beverage cans). By using embossed bevels on the pull-out plate, the distance can be doubled, forcing the pull-out plate to fold at its hinge away from the opening.

In all cases where an inclined surface is utilized, it is preferred that the peak height of the inclined surface be set adjacent to or close to the hinge, because this will help push out the pull-out plate when the cam body of the bottle cap is pushed through the opening. The inclined surface helps to expand the fracture score along its length. There are corresponding inclined surfaces or other structures on the bottom surface of the bottle cap, which will interact with the inclined surfaces on the pull-out plate. All inclined surfaces are embossed (from the bottom surface of the socket upwards), but they can also be non-embossed inclined surfaces, starting from the bottom surface of the socket to the embossed inclined surface. If the inclined surfaces of the bottle cap start from the embossed inclined surface on the cover body, the effective linear movement of the bottle cap during operation can be doubled, tripled, or even quadrupled.

Although the present invention has been described in detail with reference to specific embodiments, it will be appreciated by those skilled in the art that there are other embodiments that are equivalent to the described embodiments. Therefore, it should be understood that the present invention is not limited to the specific illustrative embodiments, but is limited only by the scope of the appended claims.
