Description

  The present invention relates to a cap attached to the mouth of a container, and more particularly to a cap that is so-called reverse tapered and whose top surface is a polygonal cap that is easy to open.

  As a cap for closing the mouth of a container, it is known to provide a projection, a so-called knurl, on the outer surface of the cap, and such a cap is widely used in bottles, pouches and the like. In the cap of a container such as coffee or soft drink, when the cap is opened and closed, a projection of a line extending in the vertical direction is formed on a so-called skirt wall corresponding to a side portion of a cylindrical shape. The projection is provided to prevent the finger from slipping when opening and closing the cap. It is what is called a knurled thing in which this protrusion was provided with two or more.

  Also, in order to save resources and reduce costs, caps with a small height and a small diameter may be used. In such a case, the contact area between the finger and the cap is reduced, and it becomes difficult to open an item that requires a large force for initial opening. Further, even with a cap having a small diameter, it is difficult for the force to be applied and it becomes difficult to open it. Therefore, there is a case in which a knurl of a special shape is formed on the skirt wall of the cap to facilitate opening.

In addition, since the cap on which the pill fur proof band is attached is cut off at the connection with the cap of the pill fur proof band when the user initially opens it after purchasing a beverage product or the like, from the time of normal opening Also require a load, and a projection may bite into the fingertip.
From such a background, various examinations have been made on the knurled shape of the cap which can be easily opened.

  Patent Document 1 has a screw portion screwed to the container opening on the inner peripheral surface, and is opened and closed by rotating along the circumferential direction of the outer peripheral surface of the cap. Forming longitudinal ribs in a direction perpendicular to the rotational direction of the cap at a predetermined interval, setting the height of the longitudinal ribs in a range of 0.2 mm to 2.0 mm, and setting the distance between adjacent longitudinal ribs to 0.5 mm A cap is disclosed in which a small rib having a height smaller than that of the longitudinal rib is formed in parallel with the longitudinal rib between the adjacent longitudinal ribs.

  Patent Document 2 has, as a container lid, a top wall and a cylindrical skirt wall depending from the periphery of the top wall, and the outer peripheral wall of the skirt wall protrudes to the outside of the outer peripheral wall. In a container lid having a skirt knurl forming area in which a plurality of linear projections extending in the vertical direction of the skirt wall are formed along the entire circumferential direction of the skirt wall, the projections are A large projecting area having a large projecting portion from the outer surface and a small projecting portion having a projecting height lower than that of the projecting portion, and the skirt wall includes the projecting portion region in which a plurality of the projecting portions are formed. And a plurality of small projections formed with a plurality of small projections, wherein the large projections and the small projections are alternately arranged in the circumferential direction of the main portion, and the large projections and the small projections are formed. An annular region extending from the upper edge of the skirt wall to the inside of the top wall Has a surface peripheral knurl formation region, the container closure, characterized in that the large protuberance regions and the small protuberance regions of the top surface peripheral knurl formation region was formed so as to protrude from the top panel wall is disclosed.

  The shape of the ribs provided on the outer peripheral surface of the cap of Patent Document 1 is a filar and has a form in which tall ribs and short ribs are alternately arranged, and is to be opened. When turning the cap in the opening direction, the surface of the finger that has entered between the longitudinal ribs abuts on the small rib, and the frictional force becomes large. For this reason, even if the cap is wet with a surfactant, detergent, solvent or the like, the hand is not slipped and it can be reliably turned.

  However, in the cap of Patent Document 1, the description that the cap has a polygonal shape, the outer side surface portion is formed of a panel, is reverse tapered, and is easy to grip is not disclosed. In addition, in the case of such a shape, since the finger is always in contact with the projection of the rib, the finger hurts when opening and closing the plug, and it is difficult to apply force.

  Further, in the cap disclosed in Patent Document 2, a large protruding area formed of a plurality of ribs and a small protruding area formed in the same manner are alternately arranged on the outer peripheral wall surface portion of the cap. It is However, as in the present application, the cap has a polygonal shape, and the outer side surface portion is formed of a panel, which is different from the reverse tapered shape and easy to grip, and the outer side surface portion is finely uneven. Therefore, extra power is required as compared with the present invention, and a finger may be ache when opened.

  Therefore, an object of the present invention is to provide a polygonal easy-to-open cap that can be opened with a small amount of force.

  The present invention is a cap having an upper surface, an outer surface, and a lower end sequentially in the axial direction, and an inner surface on the inner side, wherein the inner surface is a cylindrical cap, and the upper surface is polygonal. The lower end portion is annular, and the outer side surface portion is in contact with two adjacent vertical sides not intersecting with each other that are hanging from the corner forming the polygon of the upper surface portion, one side of the upper surface portion, and the lower end portion A panel consisting of a lower side is provided in the same number as the side provided on the upper surface, and the vertical side is characterized in that the bottom side is inclined toward the central axis passing through the center of gravity of the upper surface. .

  Furthermore, the top surface portion is in the shape of a regular polygon and has an even number of corners.

  Furthermore, one side of the top surface portion is 7 mm or more and 15 mm or less.

  Further, the longitudinal sides are each 2 mm or more.

  Furthermore, a projection is provided on the outer side surface.

  Furthermore, an imaginary angle formed by the longitudinal side or an extension thereof and a straight line parallel to one side or one side of the polygon of the top surface portion is 45 degrees to 85 degrees, and the imaginary angle is on the opening direction side It is characterized in that it is formed into

  Furthermore, a pill fur proof band is provided at the lower end portion.

  According to the present invention, there is provided a cap having a top surface portion, an outer surface portion, and a lower end portion sequentially in the axial direction and having an inner side surface portion inside, wherein the inner side surface portion is a cylindrical cap. The lower end portion is annular, and the outer surface portion is two adjacent vertical sides not intersecting with each other which are suspended from the corner forming the polygon of the upper surface portion, one side of the upper surface portion, and the lower end portion And the same number of side panels provided on the upper surface portion as the lower surface in contact with the upper surface portion, and the bottom surface portion of the vertical side is inclined toward the central axis passing through the center of gravity of the upper surface portion. Thus, the outer surface portion is a so-called reverse taper, and when the cap is turned with a finger in the opening direction, it is easy to apply pressure to the panel, the cap can be turned with a small force, and the cap can be opened easily.

  Furthermore, since the top surface portion is characterized by having a regular polygon shape and having an even number of corners, the side of the top surface portion is configured to be parallel when the cap is pinched with a finger during opening. The panel can be pinched, which is easier to grip than in the odd-numbered case, can rotate the cap with less force, and can be opened easily.

  Furthermore, since one side of the top surface portion is characterized by being 7 mm or more and 15 mm or less, a panel can be widely taken to a certain extent, and the configuration of the cap is also appropriately reverse tapered, providing a cap that is easier to pinch can do. Therefore, it can be opened easily.

As a result of the reverse taper being formed at an appropriate angle, the cap is easier to pinch and can be easily opened with less force.

  Furthermore, since the longitudinal side is characterized by being 2 mm or more in all, the surface is formed wide, and the cap can be made easier to grip and can be opened easily.

  Further, since the projection is provided on the outer side surface, the finger holding is improved and the opening can be more easily performed.

  Furthermore, an imaginary angle formed by the longitudinal side or an extension thereof and a straight line parallel to one side or one side of the polygon of the top surface portion is 45 degrees to 85 degrees, and the imaginary angle is on the opening direction side The vertical side is formed so as to hang obliquely downward toward the opening direction, and it is easy to apply force obliquely upward in the opening direction. As a result, the finger scale is improved and it is easy to open.

  Furthermore, since the pill fur proof band is provided at the lower end portion, it is clearly indicated that the initial opening has been made, and as a result, it is possible to prevent unauthorized opening and pill fur proof Opening the banded cap requires some more force than usual, but the required force can be reduced. Accordingly, a pill-fur resistant banded cap is provided that is easy to open.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 2 to FIG. 4, the cap 1 with a pill fur proof band according to the present embodiment is located at a predetermined distance below the top cylindrical cap body 10 and the cap body 10. And a plurality of connection connecting portions 30 connecting the cap body 10 and the ring portion 20. The cap 1 is configured such that the ring portion 20 is deformed at the time of initial opening, and the deformation of the ring portion 20 clearly indicates that the initial opening has been performed. In addition, although the pill fur proof band is mounted | worn with the cap 1, this is one form of embodiment, It is not limited to this. In the context of the present disclosure, the cap may also refer to the cap body.

  As shown in FIG. 1, the cap main body 10 has an outer side surface portion 11 extending in the vertical direction and a polygonal top surface portion 12 closing the upper end of the outer side surface portion 11, and is formed in an apical cylindrical shape. As shown in FIG. 1 (b), the top surface 12 is provided with a groove-like notch 19. The provision of the notches 19 is preferable because resin required for manufacturing can be reduced. Of course, the notch 19 may or may not have any shape. The perspective view of FIG. 1 is as shown in FIG. A panel having a twist may be provided on the outer surface portion 11 as shown in FIGS. 1 and 6, but it may be configured as shown in FIGS. 3, 4, 7 and 8 without a twist. Further, in the present specification, when referring to the same plane as the top surface portion 12, an extension surface, an extension line, and the like, unevenness such as the notch portion 19 or the top surface concave portion 15 is not included. As shown in FIG. 2, the inner peripheral surface of the outer side surface portion 11 is an inner side surface portion 70, and a screw 13 is formed in the inner side surface portion 70. The screw 13 engages with a screw formed in the opening of the container described later, and the cap 1 is attached to the opening of the container without looseness by the engagement of the screw. The screw 13 is a right-handed screw. The screw 13 may have any shape as long as the cap 1 can be attached to the mouth of the container without loosening.

  More specifically, the valley diameter of the screw 13 (corresponding to the outer diameter of the inner peripheral surface of the outer surface 11), the peak diameter, and the pitch (vertically adjacent screws) according to the dimensions of the screw at the mouth of the container The distance between the respective screw threads (thread valleys) 13 and 13 etc. are formed. The screw 13 may be any screw corresponding to the screw at the mouth of the container, and its shape may be a single thread screw, or may be a multiple thread screw such as a double thread screw or a triple thread screw. In addition, the winding angle, which is an angle that travels from one end of the screw 13 to the other end in a plan view, may be an angle at which the mouth of the container and the cap body 10 can be securely attached without loosening.

As shown in FIG. 3, a plurality of panels 4 are provided on the outer side surface portion 11. The panel 4 is formed by being surrounded by one side of the polygon of the top surface portion 12, the adjacent vertical sides 17 17 hanging from the corners of the top surface portion 12, and the lower side 14 which is the boundary with the lower end portion. There is. As an example of the present embodiment, the panel 4 is configured to be flat. However, the panel 4 may be a curved surface.
The lower side 14 is a line on the upper surface side of the lower end 3 and is a boundary between the lower end 3 and the outer side surface 11. And in this embodiment, the lower end portion 3 has a cylindrical shape at the portion in contact with the outer side surface, and the lower portion is a skirt shape and is formed in an annular shape, but it is not limited to this form. It may be a polygonal shape. Further, in the present embodiment, the lower side 14 has a cylindrical shape on the upper side of the lower end portion 3 and has an arc shape which bends upward because the panel 4 of the outer side surface portion 11 is a flat surface. However, the lower side 14 is not limited to this.

  Next, the panel 4 will be described in detail. The longitudinal side 17 of the panel 4 is reversely tapered with respect to the entire cap. As shown in FIG. 10A, in the present embodiment, in front view, an angle Y between the extension of a straight line X connecting the center of gravity W1 of the top surface 12 and the corner of the top surface and the extension of the vertical side 17 Is preferably 70 degrees or more and 89 degrees or less. The straight line X is on the same plane of the top surface portion 12 (the unevenness does not include the unevenness such as the top surface concave portion 15 of the top surface portion 12 in the same plane) and the center of gravity W 1 and the longitudinal side 17 On the plane where By intersecting the longitudinal side 17 or its extension line, an angle indicating the degree of reverse taper is formed. When the angle Y is 70 degrees or more and 89 degrees or less, reverse taper is appropriately applied, and it is easy to grasp the cap with a finger at the time of opening.

The panel 4 will be further described in detail with reference to FIG. The distance on the vertical line between one end and the other end of the vertical side of the panel 4 is M1. It is preferable that all M1 be 2 mm or more. However, as for the length of the longitudinal side 17 of the panel 4, it is more preferable that all are 2 mm or more. By doing this, the panel becomes sufficiently large and it becomes easy for the finger to press the panel sufficiently. As a result, it is possible to make the cap easy to grip and easy to open.
The length of one side of the top surface of the panel 4 is M2. M2 is preferably 7 mm or more and 15 mm or less. If it is shorter than this, it is relatively difficult to pinch. If it is longer than this, the size of the polygon becomes too large, and when the lower side 14 has a small cap body 10, the reverse taper becomes slightly too tight compared to 15 mm or less.

    Further, the panel 4 may be provided with a large number of small protrusions. This makes it possible to make a cap with a better finger grip. The diameter of the protrusions is preferably 5 mm or less.

    Also, as shown in FIG. 1, the panels may be twisted. When the panel 4 is twisted, the acute angle α on the top surface side is preferably 45 to 85 degrees. With such a configuration, opening can be performed with less force. That is, an imaginary angle α between the vertical side 17 or an extension thereof and one side of the polygon of the top surface 12 is 45 degrees to 85 degrees, and the end on the top side of the vertical side 17 is open. The virtual angle α is formed on the opening direction side so as to be inclined toward the plug direction. With this configuration, the finger can easily come in contact with the corner, and it can be opened with less force. However, in the present embodiment, the opening direction is H, but it is not limited to this. If the end of the top surface portion is rounded and one side of the polygon of the top surface portion 12 does not intersect the extension of the vertical side 17, a straight line parallel to one side of the polygon of the top surface portion 12; The angle formed by the longitudinal side 17 may be α. A straight line parallel to one side of the polygon of the top surface portion 12 is formed on the same plane as the top surface portion 12 at the same time as crossing an extension line with the vertical side.

  Further, as shown in FIG. 10 (b) which is an enlarged view of the area A of FIG. 6, the panel 4 is provided with a small protrusion 50. As shown in FIG. The small protrusion 50 is circular, but is not limited to circular. Further, the projection 50 may be flat on the outside in the radial direction in the cap body 10. By forming the projection 50 in a flat shape in this manner, the finger is not so painful as compared with a spherical shape or a sharp shape. Moreover, as for the size of the small protrusion, it is desirable from the viewpoint of finger rest that the diameter or the entire length be 0.1 mm to 5.0 mm.

  Referring to FIG. 2, the top surface portion 12 includes an annular top surface recess 15 extending downward from the inner surface, and an annular contact ring 16A projecting downward from the inner surface between the inner ring 16 and the outer surface portion 11. Have. The inward side of the top surface concave portion 15 of the top surface portion 12 is curved in a protruding manner toward the inside (downward in FIG. 5) of the cap main body 10. On the convexly curved central upper portion of the outer surface of the top surface portion 12, a solidified portion additionally formed at the inlet (gate) of the molten resin when the cap 1 is manufactured by injection molding adheres. 1 to 4, 6, 8, and 11 show the form after the portion is cut off.

  When the cap 1 is attached to the mouth of the container, the top surface 12, the inner ring 16, and the contact ring 16A seal the opening as the spout of the mouth. The inner ring 16 has an outer diameter larger than the inner diameter of the mouth portion, and is formed in a tapered shape in which the outer peripheral surface of the tip end portion is inclined downward and inward. When the cap 1 is attached to the mouth of the container, the inner ring 16 is inserted into the inside of the mouth and fitted with the mouth. At this time, the inner ring 16 is bent inward, and the outer peripheral surface is in close contact with the inner peripheral surface of the mouth to seal the mouth. On the other hand, when the cap 1 is attached to the opening of the container, the contact ring 16A is in close contact with the opening of the opening of the container to seal the opening.

  The inner ring 16 and the contact ring 16A may have any shape that can seal the mouth of the container, and can be appropriately designed according to the shape of the mouth. Moreover, the structure which seals the opening of the container of the cap 1 is not limited to the structure by the inner ring 16 and the contact ring 16A. For example, an annular projection is further provided which protrudes downward from the inner surface of the top surface 12 between the contact ring 16A and the outer surface 11, and when the cap 1 is attached to the mouth of the container, The circumferential surface may be in close contact with the outer circumferential surface of the mouth.

  The ring portion 20 is positioned below the cap body 10 with a predetermined distance, and is formed in a cylindrical shape coaxial with the outer side surface portion 11 of the cap body 10. The outer diameter of the ring portion 20 is substantially the same as the outer diameter of the outer peripheral surface of the lower end portion of the outer side surface portion 11, and the inner diameter is larger than the outer diameter of the inner peripheral surface of the lower end portion of the outer side surface portion 11. That is, the thickness of the ring portion 20 in the radial direction is thinner than the lower end portion of the outer side surface portion 11.

  As shown in FIGS. 4 and 9, in the ring portion 20, a plurality of plate-like arc-shaped portions 21 curved in an arc shape are connected in a cylindrical shape via thin connecting portions 22 formed to be thin in thickness. Be done. Here, although the ring part 20 is the structure by which the plate-like arc-shaped parts 21 and 21 curved in 2 substantially semicircular arc shape are connected, the number of the arc-shaped parts 21 which comprise the ring part 20 is limited Alternatively, three arc-shaped portions or four arc-shaped portions curved in an arc shape may be connected in a tubular shape.

  A thin connecting portion 22 is formed between circumferential ends of two adjacent arc-shaped portions 21, 21. In detail, the end in the closing direction in the circumferential direction of one arc-shaped portion 21 is connected to the end in the opening direction in the circumferential direction of the other arc-shaped portion 21 via the thin connecting portion 22. Further, the end in the opening direction in the circumferential direction of one arc-shaped portion 21 is connected to the end in the closing direction in the circumferential direction of the other arc-shaped portion 21 via the thin connecting portion 22.

  The thin link 22 is located at the lower end opposite to the side of the outer surface 11 of the arc 21, and the lower end of the thin link 22 is formed flush with the lower end of the arc 21. The inner surface of the thin connecting portion 22 is formed flush with the inner peripheral surface of the arc-shaped portion 21. The thin-walled connecting portion 22 is formed such that the outer peripheral side is cut into a substantially V shape in a bottom view, the thickness in the radial direction becomes thin, and the width in the circumferential direction becomes narrow. Further, as shown in FIG. 3 and FIG. 7, in the front view, the upper side which is the side of the outer surface portion 11 is notched in a substantially V shape, and the width in the vertical direction and the circumferential direction It is formed to be narrow. Here, FIG. 9A is an enlarged view of a portion VI of FIG. 9B, and is an enlarged view of the thin connecting portion 22 and the vicinity thereof. And the thin-walled connecting portion 22 formed to have a small thickness is configured to be broken at the time of opening. In addition, while connecting the arc-shaped part 21, the thin connection part 22 should just be the structure which can be fractured | ruptured at the time of opening, and the position in which the thin connection part 22 is formed is not limited. However, it is preferable that the lower end of the thin connecting portion 22 be formed flush with the lower end of the arc-shaped portion 21 from the viewpoint of the transport suitability of the cap 1 and the like. Entanglement is prevented. In addition, the ring portion 20 may have a configuration in which adjacent arc-shaped portions 21 are tubularly connected by a plurality of thin connecting portions 22.

  Each of the arc-shaped portions 21 has a ratchet pawl 23 which protrudes inward from the inner circumferential surface. The ratchet claw 23 is formed corresponding to a ratchet protrusion described later formed on the mouth of the container. The ratchet pawl 23 is formed on the side in the opening direction with reference to the circumferential center of the arc-shaped portion 21. The inner periphery of the arc-shaped portion 21 passes through the joint portion between the end surface of the ratchet claw 23 in the unsealing direction and the inner peripheral surface of the arc-shaped portion 21 (the end surface of the ratchet claw 23 in the unsealing direction) The angle with the surface (face in contact with the face) is an acute angle. On the other hand, the end face of the closing direction of the ratchet pawl 23 and the inner circumferential surface of the arc-shaped portion 21 (the joint portion between the end surface of the closing direction of the ratchet pawl 23 and the inner circumferential surface of the arc 21) The angle with the inner circumferential surface) is an obtuse angle. The ratchet claw 23 does not engage with the ratchet projection of the opening when closing the opening of the container, and engages with the ratchet projection of the opening when opening the opening. The shape and configuration of the shape 21 are not particularly limited as long as the rotation of the material 21 in the opening direction is restricted.

  Here, the ring portion 20 has a tapered portion 24 whose diameter increases from the lower end opposite to the side of the outer side surface 11 toward the upper side which is the side of the outer side surface 11. That is, in the two arc-shaped parts 21 and 21 which constitute the ring part 20, the taper part 24 which diameter-expands toward upper direction from the lower end is formed. Although the upper end of the tapered portion 24 is positioned above the upper end of the thin connecting portion 22, the range of the tapered portion 24 is not limited. However, from the viewpoint of mold releasability from the mold, the upper end of the tapered portion 24 is located above the upper end of the thin connecting portion 22, and the thin connecting portion 22 is included in the area of the tapered portion 24 in front view. Is preferred.

  The connecting portion 30 is formed corresponding to each of the arc-shaped portions 21 of the ring portion 20.
