Description

CONTAINER CAP AND CONTAINER HAVING THE SAME

The present invention relates to a stopper and a container having the same, and more specifically, to a separable stopper having a double barrier membrane that allows different types of contents to be separated and contained before the stopper is opened and allows different types of contents to be consumed together when the stopper is opened and the contents are consumed, and a container having the same.

Containers such as bottles for holding various beverages and seasonings are very useful to modern people.

Among these containers, containers equipped with a separable functional stopper that has a separate space distinct from the internal space of the container body have been developed and are being sold commercially.

The separation space provided in the stopper accommodates contents of a different form (e.g., secondary contents) from the contents contained in the main body of the container.

Therefore, when a user opens the stopper combined with the main body of the container to ingest the main content, the secondary content contained in the stopper is also ingested.

However, due to the problem of sealing force of the separation space of the stopper containing the secondary contents, a problem occurs in which the main contents and the secondary contents of the stopper are mixed in the main body of the container, which is mainly composed of liquid.

Hereinafter, embodiments of the present invention will be described with reference to the attached drawings.

First, a container (1) equipped with a stopper (100) according to one embodiment of the present invention will be described with reference to FIGS. 1 to 7.

The container (1) of this example may have a container body (200) that is provided with a stopper (100) and a fastening member (202) having screw threads (2021) on the outer side thereof, and is connected to the stopper (100) through the fastening member (202).

It may have an internal space (S200) in which contents (e.g., main contents) are contained.

As illustrated in FIGS. 1 and 2, the plug (100) of the present example may have a plug body (110) coupled to a container body (200), a receiving member (120) coupled to the plug body (110), and a temporary fixing member (130) coupled to the plug body (110).

The plug body (110) can be combined with a receiving member (120) as shown in Fig. 2 to have the receiving member (120) built into the inside. This plug body (110) can be combined with a container body (200) to form a container (1).

As shown in FIGS. 2 to 4, the plug body (110) may have an upper portion (111) having a circular flat shape, a side portion (112) connected to the upper portion (111), a first blocking film (113) and a second blocking film (114) connected to the upper portion (111), and a joining wall (115) connected to the upper portion (111).

The upper part (111) is a part forming the upper surface of the plug body (110), and may be a plate shape having a circular flat shape with a circular sunken part (S111) in the outer center part of the upper part (111). At this time, the sunken part (S111) may be omitted as needed, and if the sunken part (S111) exists, the aesthetics of the plug (100) may be further improved.

The side (112) may extend from the edge of the upper portion (111) in a direction intersecting the upper portion (111) (e.g., in a direction perpendicular to the ground).

The inner side of the side (112) may be provided with screw threads (1121) and a plurality of catches (1122) (e.g., first engaging portion) for engaging with the receiving portion (121).

The screw thread (1121) may be screw-connected with the screw thread (2021) of the container body (200) to connect the cap (100) and the container body (200) to each other. In this example, the screw having the screw thread (1121) may be a double-row screw having two screw threads (1121).

Accordingly, the screw of the container body (200) forming the screw thread (2021) for screw connection with the stopper body (110) may also be a double-row screw, and the pitch of the screw of the container body (200) and the screw of the stopper body (110) may be the same, and the lead of the screw of the container body (200) and the screw of the stopper body (110) may also be the same.

Each catch (1122) can be spaced apart from the inner surface of the upper portion (111) by a minimum distance (D1). Here, D1 is the minimum separation distance of the catch (1122).

Each may be positioned higher than the screw thread (1121), that is, closer to the inner surface of the upper portion (111) than the screw thread (1121).

In this example, a plurality of catches (1122) are provided to prevent the stopper body (110) from being detached from the stopper body (110) or from being changed into an abnormal state when the stopper body (110) is moved over the container body (200) for combination with the container body (200) or transported to another area while the stopper body (110) is combined with the receiving member (120).

These multiple catches (1122) may all have the same structure and may be positioned spaced apart from each other by a set interval. For example, the number of catches (1122) is four, but is not limited thereto and may be changed and may be two or more.

As shown in Fig. 4, the catch (1122) may be a screw thread that protrudes from the inside of the side (112) toward the inside, that is, toward the joining wall (115), and is extended in a spiral shape by a predetermined length while being inclined at a predetermined angle.

On the outside of the side (112), a plurality of grooves and protrusions may be alternately positioned in the extension direction of the side (112). These grooves and protrusions enable the user to open and close the stopper (100) more easily.

The first blocking film (113), the second blocking film (114), and the joining wall (115) located at the upper portion (111) can extend downward from the inner surface of the upper portion (111), i.e., in a direction intersecting the ground (for example, in a direction perpendicular to the ground), as shown in FIG. 2.

As illustrated in Fig. 2, the respective extension lengths of the first blocking film (113), the second blocking film (114), and the bonding wall (115) may be different from each other. For example, the extension length of the second blocking film (114) may be the longest, and the extension length of the bonding wall (115) may be the shortest.

These first blocking film (113) and second blocking film (114) can be extended until they come into contact with the upper surface of the corresponding portion of the receiving member (120) located at the bottom. On the other hand, the joining wall (115) can come into contact with the corresponding portion of the receiving member (120) located at the outside.

In addition, as shown in FIGS. 3 and 4, the first blocking film (113), the second blocking film (114), and the bonding wall (115) may be positioned spaced apart from each other along the plane direction at a set interval from the inside to the outside of the upper part (111), and may each be in the form of a wall having a circular plane shape.

At this time, the first barrier (113) and the second barrier (114) can perform a dam function that surrounds the periphery in a circular shape as shown in Fig. 2.

The receiving member (120), as already described, may be combined with the plug body (110) and positioned inside the plug body (110).

This receiving member (120) may have the same planar shape as the stopper body (110), for example, a circular planar shape, for combination with the stopper body (110).

As illustrated in FIGS. 2 and 5, the receiving member (120) may include a receiving portion (121), a first flat portion (122) connected to the receiving portion (121) and extending outwardly flat, a second flat portion (123) connected to the first flat portion (122) and extending outwardly flat, a plurality of pillar portions (124) connected to the second flat portion and extending upward, a frame portion (125) coupled to the upper end of the pillar portion (124) and positioned at the upper end of the pillar portion (124), and a hook portion (126).

The receiving portion (121) may be a portion where contents (e.g., main contents) and other contents (e.g., secondary contents) contained in the container body (200) are located.

This receiving portion (121) may have a circular flat shape that protrudes upward and is connected to the first flat portion (122) without interruption.

Accordingly, the receiving portion (121) is connected to the first flat portion (122) and may have a side surface protruding from the first flat portion (122) by a set length and an upper surface connected to this side surface.

At this time, as an example, a sunken recessed portion (1211) may exist in the center of the upper surface of the receiving portion (121). However, in an alternative example, the sunken portion (1211) may be omitted, and in this case, the upper portion (111) of the receiving member (120) may have a receiving portion (121) that is a flat surface without a sunken portion.

In this way, when the recessed portion (1211) is positioned on the upper surface of the receiving portion (121), the solid content (not shown), such as a capsule-shaped nutritional supplement, can be stably positioned on the upper surface of the receiving portion (121).

The first flat portion (122) and the second flat portion can be connected to the receiving portion (121) in a step-like manner without interruption.

The first flat portion (122) and the second flat portion may each have a flat surface extending outwardly along a plane direction parallel to the ground, and the heights of the upper surfaces of the receiving portion (121), the first flat portion (122), and the second flat portion may sequentially decrease. Accordingly, the upper surface height of the first flat portion (122) may be higher than the upper surface height of the second flat portion, and the upper surface height of the receiving portion (121) may be higher than the upper surface height of the first flat portion (122).

Due to this, the receiving portion (121), the first flat portion (122), and the second flat portion become lower in height as they go downward, so that the side of the receiving member (120) can have a step shape, and the receiving portion (121) where the contents are located can be located at the highest point.

As illustrated in Fig. 2, the first flat portion (122) and the second flat portion can function as supports on which the first blocking film (113) and the second blocking film (114) are positioned, respectively.

Accordingly, the end of the first blocking film (113) extending downwards can be positioned and adhered to the upper surface of the first flat portion (122), and the end of the second blocking film (114) extending downwards can be positioned and adhered to the upper surface of the second flat portion.

Due to this, the first flat portion (122) and the second flat portion can receive pressure applied from above to below by the first blocking film (113) and the second blocking film (114) that they are in contact with, respectively.

In this way, the first blocking film (113) and the second blocking film (114) are positioned on the first and second plane portions, which are spaced apart from each other along the plane direction at a set interval, so that pressure can be applied.

Accordingly, the plug body (110) may be provided with a receiving space (S101) of a receiving portion (121) surrounded by a first blocking film (113) and a receiving space (S102) located between the first blocking film (113) and the second blocking film (114).

The accommodation space (S101) is a space surrounded by a portion of the upper part (111) of the plug body (110), the first blocking film (113), and the accommodation portion (121), and the contents located in the accommodation portion (121) can be located therein. This accommodation space (S101) can maintain a sealed state by being blocked from the outside by the first blocking film (113) and the second blocking film (114).

The accommodation space (S102) may be a closed space surrounded by the first blocking film (113), the second blocking film (114), the first flat portion (122), the second flat portion, and a portion of the upper portion (111).

By means of this accommodation space (S102), the accommodation space (S101) can be maintained in a state of being further isolated from the outside.

A plurality of pillar sections (124) can be connected to the second flat section and positioned on the outside of the second flat section.

These multiple column sections may all have the same shape and may extend in a direction different from the extension direction of the first flat section (122) and the second flat section (e.g., upward).

A plurality of pillar sections (124) can be positioned at set intervals along the outer perimeter of the second flat section.

Accordingly, a through hole (S124), which is an empty space, can be located between two adjacent pillars (124).

One end of each pillar (124) can be connected to the second flat part, and the other end can be connected to the frame part (125).

At this time, each pillar part (124) may extend perpendicularly to the ground when extending from the lower part to the upper part (111), then extend upward at an angle less than 90 degrees to the ground, and then extend perpendicularly to the ground again. Each of these pillar parts (124) may extend in a straight line, in a curved line, or may have both a straight section and a curved section.

In this example, the receiving member (120) may contain an elastic material (e.g., silicone or natural rubber), and in this case, the receiving member (120) may have elasticity.

Accordingly, when the extension width of the second flat portion is smaller than the thickness of the second blocking film (114) positioned thereon, when the second blocking film (114) is inserted into the empty space between the connecting portion connecting the first flat portion (122) and the second flat portion and the pillar portion (124), the second blocking film (114) can be inserted into the corresponding position by compressing and pushing the portion of the closely-contacting receiving member (120).

When the second blocking film (114) is lowered to a set position and the combination with the receiving member (120) is completed, the corresponding portion of the receiving member (120) is restored to its position by elasticity and pressure is applied toward the second blocking film (114), thereby increasing the sealing force of the second blocking film (114).

In this way, as the second blocking film (114) is inserted and positioned in the second flat portion of the receiving member (120), the plurality of through holes (S124) and the inner side of the pillar portion (124) are blocked, so that the plurality of through holes (S124) are blocked by the second blocking film (114).

The fluid content (e.g., fermented lactic acid bacteria beverage, etc.), which is the content (e.g., main content) contained in the container body (200), can move toward the receiving member (120) through the open through-hole (S124).

However, as described above, since the plurality of through holes (S124) surrounding the receiving portion (121) are blocked by the second blocking film (114), the movement of the fluid contents toward the receiving member (120) may be blocked or the inflow amount may be significantly reduced.

In addition, since the first flat portion (122) and the second flat portion connected to the receiving portion (121) are positioned in a step shape, and the upper surface height of the receiving portion (121) where the secondary contents are positioned is highest than the plane heights of the first flat portion (122) and the second flat portion, it may be even more difficult for the main contents to flow into the receiving space (S101) of the receiving portion (121).

Furthermore, the phenomenon of the main contents flowing into the accommodation space (S101) where the secondary contents are located can be prevented by the accommodation space (S102) existing on the first blocking film (113) and the second blocking film (114).

The edge portion (125) of the receiving member (120) is inserted into the upper portion (111) of the fastening portion (202) of the container body (200) to position the receiving member (120) in the container body (200).

These border portions (125) can be connected to the upper portions of multiple pillar portions (124), protrude upward from the upper portions, extend outwardly parallel to the ground, and then extend downward again.

Accordingly, the edge portion (125) may have a first portion (1251) protruding upward, a second portion (1252) connected to the first portion (1251) and extending outwardly parallel to the ground, and a third portion (1253) connected to the second portion (1252) and extending downward.

In this example, since the first part (1251) of the frame portion (125) is positioned without a break between two adjacent pillar portions (124), the plane shape of the frame portion (125) can have a ring shape.

By these first to third parts (1251-1253), a groove exists on the lower side of the frame (125), and this groove can be inserted into the upper part (111) of the fastening part (202) of the container body (200).

Accordingly, when the receiving member (120) is inserted into the injection port of the container body (200) and the groove of the rim (125) is inserted into the upper portion (111) of the fastening portion (202), as shown in FIG. 2, the joining wall (115) of the stopper body (110) can be in close contact with the inner surface of the adjacent first portion (1251).

By this close contact action, the receiving member (120) can be maintained in a combined state with the plug body (110).

As illustrated in FIGS. 5 to 7, the outer surface of the third portion (1253) may be provided with a plurality of spiral projections (1254) (e.g., second connecting portions) that hang over a plurality of catches (1122) of the plug body (110) and are connected with the catches (1122).

Accordingly, the catch (1122) can overlap with the spiral projection (1254). In this example, the protrusion height (H11) of the catch (1122) can be greater than the protrusion height (H12) of the spiral projection (1254), and the difference between the protrusion height (H11) of the catch (1122) and the protrusion height (H12) of the spiral projection (1254) can be approximately 0.3 mm.

However, the difference between the protrusion height (H21) of the screw thread (1121) formed on the stopper body (110) and the protrusion height (H22) of the screw thread (2021) located on the container body (200) may be less than the difference in protrusion height between the catch (1122) and the spiral projection (1254). That is, the overlapping width (W11) of the protrusion height (H21) of the screw thread (1121) formed on the stopper body (110) and the screw thread (2021) located on the container body (200) may be longer than the overlapping width (W12) of the catch (1122) and the spiral projection (1254), so that the bonding force between the stopper body (110) and the container body (200) may be greater than the bonding force between the stopper body (110) and the receiving member (120).

A plurality of spiral projections (1254) may be positioned spaced apart from each other by a set interval along the direction of progression of the outer surface of the third portion (1253), as illustrated in FIG. 6, and may be included in at least one spiral projection set. The number of spiral projections (1254) provided in each spiral projection set may be one or more.

As illustrated in FIG. 7, as an example, four sets of spiral projections may be provided, and the sets of spiral projections facing each other on opposite sides may have the same number of spiral projections (1254).

In Fig. 7, there may be two sets of spiral projections (1254) each having five spiral projections (1254), and there may be two sets of spiral projections (1254) each having one spiral projection (1254).

The inclination angle (θ1) of each spiral projection (1254) is the same, the heights of the start positions (SP12) of all spiral projections (1254) are the same, and the heights of the end positions (EP12) can also be the same.

When there are multiple sets of spiral protrusions (1254), a portion where no spiral protrusions (1254) are located, i.e., a portion where no protrusions are formed (PR1), may exist between two adjacent sets of spiral protrusions (1254). At this time, the number of portions where no protrusions are formed (PR1) may be the same as the number of catches (1122).

In a set of identical spiral projections (1254), the start position (SP12) and end position (EP12) of two adjacent spiral projections (1254) can be located on the same virtual vertical line (L1).

The plug body (110) and the receiving member (120) of the present example may be made of an elastic material, and thus, the plurality of spiral projections (1254) may be positioned over the adjacent catches (1122) by way of a forced fit method or the like.

In addition, the difference between the protrusion height (H11) of the catch (1122) and the protrusion height (H12) of the spiral projection (1254) is approximately 0.3 mm, which is larger than approximately 0.1 mm, which is generally the case for screw defects, so that when the plug body (110) rotates, the catch (1122) formed on the plug body (110) may pass over the spiral projection (1254), causing the plug body (110) to rotate.

At this time, the width of the protrusion-free portion (PR1) may be shorter than the straight-line distance (L11) of each catch (1122), that is, the straight-line distance connecting the start point (SP11) and the end point (EP11) of the catch (1122) parallel to the ground, than the width (L12) of the protrusion-free portion (PR1), that is, the straight-line distance in the parallel direction.

Accordingly, the non-protrusion-formed portion (PR1) can function as an insertion area for each catch (1122), so that the catch (1122) can be more easily combined with the spiral protrusion (1254).

For example, after the receiving member (120) or the plug body (110) is rotated in the corresponding direction so that the engaging protrusion (1122) can be positioned in the unformed portion (PR1), a physical force is applied to at least one of the plug body (110) and the receiving member (120) so that the first blocking film (113) and the second blocking film (114) can be positioned on the first flat portion (122) and the second flat portion of the receiving member (120), respectively.

Then, the main body cap or receiving member (120) is rotated so that the spiral projection (1254) can be positioned on the catch (1122).

In addition, since the catches (1122) of the plug body (110) are positioned in multiple places spaced apart from each other, the restraining fitting operation can be performed with less force.

Furthermore, since the engaging jaw (1122) is formed as one piece that is connected without interruption along the inner surface of the stopper body (110), the bonding force with the spiral projection (1254) is weakened, so that when the stopper body (110) is released from the container body (200), the receiving member (120) can be stably maintained in a state of being connected to the container body (200).

In this example, the inclination direction and inclination angle (θ1) of each spiral protrusion (1254) may be identical to the inclination direction and inclination angle of each catch (1122), respectively.

Additionally, the inclination direction and inclination angle (θ1) of each spiral projection (1254) may be identical to the inclination direction and inclination angle of the screw thread (1121) located on the plug body (110).

Due to this, the leads of the catch (1122), the spiral projection (1254) and the screw thread (1121) can be the same as each other, so that the leads of the catch (1122) and the spiral projection (1254) coupled to each other and the leads of the screw thread (1121) and the screw thread (2021) located on the container body (200) can be the same as each other.

Unlike the present example, in an alternative example, the pitch of the spiral projection (1254) and the pitch of the defect groove may be the same, and the pitch of the screw thread (1121) of the plug body (110) and the pitch of the screw thread (2202) of the container body (200) may also be the same.

Additionally, the pitch of the spiral projection (1254) and the defect groove may be the same as the pitch of the screw thread (1121) of the plug body (110) and the screw thread (2021) of the container body (200).

Accordingly, the rotational motion of the plug body (110) is ensured to be able to rotate normally in the corresponding direction without being adversely affected by the spiral projection (1254) and the catch (1122).

In this way, when a portion of a plurality of spiral projections (1254) is positioned on a plurality of catches (1122) located on the inside of the side (112) of the plug body (110), the plurality of catches (1122) can move up and down along the adjacent spiral projections (1254) according to the rotation of the plug body (110).

In this way, since the catch (1122) of the plug body (110) moves up and down along the spiral projection (1254) of the receiving member (120), the plug body (110) can also move up and down according to the rotational motion to perform an opening and closing motion.

At this time, the range of movement of the plug body (110) in the third part (1253) by the spiral projection (1254) can be determined according to the height (H3) of each spiral projection (1254).

In this example, the minimum separation distance (D1) of the catch (1122) can be determined according to the height (H3) of the spiral projection (1254), and the height (H3) of the spiral projection (1254) can be shorter than the minimum separation distance (D1) of the catch (1122).

As described above, the receiving member (120) can be combined with the plug body (110) by the action of the first blocking film (113), the second blocking film (114) and the bonding wall (115) by an externally applied force.

In this case, as already described, the bonding state of the container body (200) and the receiving member (120) may be released or changed by an external impact, a physical force applied downward, or the self-weight of the receiving member (120).

However, since the receiving member (120) is coupled to the plug body (110) by a plurality of catches (1122) and a plurality of spiral projections (1254), unless the receiving member (120) is forcibly removed from the plug body (110), such as by a worker or a rotational movement of the plug body (110), the receiving member (120) can maintain a normal coupled state without being detached from the plug body (110).

Therefore, in the process of transporting or positioning the plug body (110) combined with the receiving member (120) on the container body (200), the body plug and the receiving member (120) can maintain a normal combined state.

In addition, when the plug body (110) is rotated in the corresponding direction (e.g., to the right) to couple the plug body (110) to which the receiving member (120) is coupled with the container body (200), the catch (1122) located on the plug body (110) can descend along the spiral projection (1254) located on the receiving member (120).

At this time, since the minimum separation distance (D1) of the catch (1122) is shorter than the height (H3) of the spiral projection (1254), when the catch (1122) is located at the lowest position of the spiral projection (1254), the plug body (110) can apply pressure toward the receiving member (120).

Due to this, the close contact between the first blocking film (113) and the second blocking film (114) can be further increased, so that the sealing effect by the first blocking film (113) and the second blocking film (114) can be further improved.

In this example, the movement width of the screw thread (1121) of the plug body (110) moving along the screw thread (2021) of the container body (200) may be greater than the movement width (i.e., H3) of the catch (1122) moving along the spiral projection (1254).

Accordingly, even after the catch (1122) moves to the lowest along the spiral projection (1254), the plug body (110) can be lowered additionally. Accordingly, when the plug body (110) is additionally rotated to perform a lowering operation, additional pressure is applied toward the receiving member (120) by the lowering plug body (110), so that the rim (125) can be inserted into the upper portion (111) of the container body (200) and firmly fixed.

At this time, when the stopper body (110) rotates in the corresponding direction and descends while the catcher (1122) has moved to the lowest position of the spiral projection (1254), the protrusion height (H11) of the catcher (1122) is greater than the protrusion height (H12) of the spiral projection (1254), so that the catcher (1122) may sequentially ride over the spiral projections (1254) positioned parallel to each other along the rotation direction, thereby causing a phenomenon of rotation. Accordingly, the rotational motion of the stopper body (110) can be performed normally without being affected by the catcher (1122) and the spiral projection (1254).

As described above, the difference between the protrusion height (H21) of the screw thread (1121) formed on the stopper body (110) and the protrusion height (H22) of the screw thread (2021) located on the container body (200) is smaller than the difference in protrusion height between the catch (1122) and the spiral projection (1254), so that the bonding force between the stopper body (110) and the container body (200) can be greater than the bonding force between the stopper body (110) and the receiving member (120). Accordingly, the stopper body (110) coupled to the container body (200) can be lowered to the corresponding height while maintaining normal screw bonding with the container body (200) without a turning phenomenon, thereby safely closing the stopper body (110).

A plurality of hook portions (126) can protrude inwardly [i.e., toward the fixing member (120)] from the third portion (1253) of the edge portion (125).

This hook portion (126) can be joined to a sunken portion on the outer surface of the upper portion (111) of the fastening portion (202) of the container body (200).

Through the hook portion (126) like this, the fixing member (120) can be firmly connected to the container body (200).

The temporary fixing member (130) surrounds the container body (200) and is connected to the stopper body (110) and at least a portion of the container body (200).

In addition, the temporary fixing member (130) is separated from the container body (200) at least in part as the plug body (110) rotates due to an external force. The temporary fixing member (130) may include a connecting member (131) connected to the plug body (110) and an undercut member (132) connected to the connecting member (131) and positioned on the outer surface of the container body (200).

In this state, when the plug body (110) is rotated in the corresponding direction (e.g., rotational direction) to open and close the plug (100), the connecting portion (131) may be separated from the undercut portion (132) while the connection state is broken.

The connecting portion (131) is located between the plug body (110) and the undercut portion (132) as shown in Fig. 2, and can connect the plug body (110) and the undercut portion (132) to each other.

Since these connecting parts (131) are positioned spaced apart along the lower edge of the plug body (110) at set intervals, the number of connecting parts (131) may be plural.

When these connecting parts (131) are viewed from above (111) or below, they can be seen to be arranged radially.

This connection part (131) can be broken by the rotational motion of the plug body (110), thereby separating the plug body (110) of this example from the container body (200).

That is, when a user applies an external force to rotate the plug body (110), the connecting portion (131) is separated upward and the undercut portion (132) may remain on the outer surface of the container body (200) in place.

As a result, the connecting portion (131) is separated from the connected plug body (110) and the undercut portion (132), so that the plug body (110) can also be separated from the undercut portion (132) located in the container body (200).

Then, the screw thread (1121) and the catch (1122) of the plug body (110) can move upward in a spiral shape along the corresponding screw thread (2021) of the container body (200) and the spiral projection (1254) of the receiving member (120), respectively, to release the combined state.

This allows the user to open the plug body (110) by separating the plug body (110) from the container body (200) and the receiving member (120).

When the opening and closing of the plug body (110) is completed, a receiving member (120) can be positioned in the upper part (111) of the container body (200).

The undercut portion (132) may have a 'V' shape with an empty interior as shown in Fig. 2. Accordingly, the undercut portion (132) may be inserted and connected to a catch (1122) (not shown) located on the outer surface of the container body (200). At this time, the catch (1122) may also prevent the rotational motion of the undercut portion (132).

Even when the plug body (110) is rotated by this insertion connection, the undercut portion (132) is positioned without rotating on the corresponding outer surface of the container body (200), so that the connecting portion (131) is easily broken and the plug body (110) is opened.

When a plug (100) having such a structure blocks the injection port of the container body (200) by screw-connecting the plug body (110) to the fastening part (202) of the container body (200), a sealed internal space (S200) is formed inside the container body (200).

In addition, inside the stopper (100) in which the stopper body (110) and the receiving member (120) are combined, an receiving space (S101) formed by the upper part (111) of the stopper body (110), the first blocking film (113), and the receiving portion (121) of the receiving member (120) is formed.

According to this example, when the cap body (110) and the receiving member (120) are combined before opening, the receiving space (S101) where the secondary contents are located is blocked by two blocking films, the first blocking film (113) and the second blocking film (114), so that the sealing force of the receiving space (S101) increases, so that the primary contents in the internal space (S200) of the container body (200) and the secondary contents located in the receiving member (120) do not mix with each other.

In addition, when the plug body (110) is opened by rotating the plug body (110) in the corresponding direction,

The bonding force between the stopper body (110) and the container body (200) by the edge portion (125) and the hook portion (126) of the container body (200) and the receiving member (120) may be greater than the bonding force between the stopper body (110) and the receiving member (120) by the spiral projection (1254), the first blocking film (113), the second blocking film (114) and the bonding wall (115).

Due to this, when the stopper body (110) is separated from the container body (200) by the rotation of the stopper body (110), the stopper body (110) and the receiving member (120) are also separated from each other, so that only the receiving member (120) can remain connected to the container body (200).

Accordingly, by the separation operation of the plug body (110), the blocked state of the second blocking film (114) blocking the plurality of through holes (S124) can be released, and the through holes (S124) can be opened.

Due to this, the main content, which is the fluid content of the container body (200), flows into the receiving space (S101) through the through hole (S124), so that when the user drinks the main content in the container body (200), the secondary content located in the receiving member (120) can also be comfortably and conveniently consumed.

That is, until the stopper (100) is opened, the main and secondary contents contained in the main body (200) and the stopper (100) are prevented from mixing with each other, thereby preventing problems such as deterioration of the two contents, and thus the components of each of the main and secondary contents can be kept fresh without deterioration.

Next, a container (1a) according to another embodiment of the present example can be described with reference to FIGS. 8 to 11.

Compared to FIGS. 1 to 7, components having the same structure and performing the same operation are given the same drawing reference numerals and detailed descriptions thereof may be omitted.

The container (1a) of the present example illustrated in FIGS. 8 to 11 may also be provided with a stopper (100a) and a container body (200) coupled with the stopper (100a).

The container body (200) may be provided with an internal space (S200) in which the main contents are stored and a fastening part (202) for connection with a stopper (100a) as described with reference to FIGS. 1 to 7.

The stopper (100a) of this example may also be provided with a stopper body (110a) coupled to a container body (200), a receiving member (120a) coupled to the stopper body (110a), and a temporary fixing member (130) coupled to the stopper body (110a).

The plug body (110a) of this example may also have an upper part (111), a side part (112a) connected to the upper part (111), a first blocking film (113) and a second blocking film (114) connected to the upper part (111), and a joining wall (115) connected to the upper part (111).

The plug body (110) of this example has the same structure as the plug body (110) of the example described with reference to FIGS. 1 to 7 in terms of the structure of the upper part (111), the first blocking film (113), the second blocking film (114), and the joining wall (115) except for the side part (112a), so a description thereof is omitted.

The side (112a) of the plug body (110a) of the present example may also extend from the edge of the upper part (111) in a direction intersecting the upper part (111), and the inner side of the side (112a) may be provided with screw threads (1121) for coupling with the container body (200a) and a plurality of catches (1122a) (e.g., first coupling portions) for coupling with the receiving portion (121). The catches (1122a) of the present example may also have the same structure and may be positioned spaced apart from each other by a set distance.

In this example, the number of catches (1122a) is also four, but this number can be changed as needed, and it may be preferable to have at least two. In addition, each catch (1122a) can be positioned higher than the screw thread (1121).

However, each of the catches (1122a) of the plug body (110a) described with reference to FIGS. 1 to 7 may have a spiral shape so that the heights are not different depending on the position, but may have a parallel line shape with the same height depending on the position.

The receiving member (120a) may also include a receiving portion (121), a first flat portion (122) and a second flat portion (123) sequentially connected to the receiving portion (121) in a step shape, a plurality of pillar portions (124) connected to the second flat portion and extending upward, a frame portion (125) coupled to the upper end of the pillar portion (124) and positioned at the upper end of the pillar portion (124) and having first to third portions (1251-1253), and a hook portion (126).

A through hole (S124) through which the main contents contained in the container body (200) pass may be located between two adjacent pillars (124).

The receiving member (120a) of this example may have a single engaging groove (e.g., second engaging portion) (1254a) formed along the third portion (1253) instead of a plurality of spiral projections (1254) located on the third portion (1253) of the edge portion (125).

Since the receiving member (120a) has a circular flat shape and the third part (1253) is also formed in a circular shape, the engaging groove (1254a) located in the third part (1253) can also be formed in a circular shape.

This catch groove (1254a) may be a portion where multiple catch protrusions (1122a) are inserted and positioned for the side (112a) of the plug body (110a).

At this time, the catch (1122a) can be inserted into the corresponding part of the catch groove by a forced fit.

In this example, the difference between the protruding height (H21) of the screw thread (1121) formed on the plug body (110a) and the protruding height (H22) of the screw thread (2021) located on the container body (200) may be less than the difference between the protruding height of the catch (1122a) and the recessed depth of the catch groove (1254a). That is, the protrusion height (H21) of the screw thread (1121) formed on the plug body (110a) and the overlapping width (W21) of the screw thread (2021) located on the container body (200) may be greater than the overlapping width (W22) of the engaging groove (1254a) and the engaging step (1122a) (i.e., the length of the engaging step (1122a) inserted into the engaging groove (1254a)), so that the bonding force between the plug body (110a) and the container body (200) may be greater than the bonding force between the plug body (110a) and the receiving member (120a).

Due to this, the catch (1122a) inserted into the catch groove (1254a) can be easily removed from the catch groove (1254a) when the stopper body (110a) rotates for the downward movement of the stopper body (110a).

By the engagement action of the catch (1122a) and the catch groove (1254a), the receiving member (120a) maintains a stable engagement state inside the plug body (110a), so that the engagement state may not be released by the weight of the receiving member (120a) or external impact.

At this time, when the catch (1122a) is formed as a plurality of catches spaced apart from each other compared to the case where the catch (1122a) is formed as one without any break along the direction of travel of the third part (1253), the bonding force with the catch groove (1254a) may decrease.

In order to open the plug body (110a), when the body plug (110a) is rotated in the corresponding direction, the body plug (110a) can be easily separated from the receiving member (120a), so that the receiving member (120a) can remain connected to the upper portion of the fastening member (202) of the container body (200).

In this way, when the plug body (110a) and the receiving member (120a) are inserted by the engaging step (1122a) and the engaging groove (1254a), and the plug body (110a) is rotated in the corresponding direction to be screw-coupled with the container body (200), pressure is applied toward the receiving member (120a) according to the downward movement of the plug body (110a), so that the sealing force of the first blocking film (113) and the second blocking film (114) increases, and also the bonding force between the receiving member (120a) and the container body (200) can be increased.

Conversely, when the plug body (110a) is rotated in the corresponding direction to separate the plug body (110a) from the container body (200), the engaging protrusion (1122a) inserted into the engaging groove (1254a) can be naturally removed due to the rising motion of the plug body (110a).

Due to this, the cap body (110a) can be detached from the receiving member (120a) and separated from the receiving member (120a) while maintaining the state of being coupled with the container body (200).

This example can have additional effects, including a simpler and easier structure, in addition to the effects exhibited by FIGS. 1 to 7.

The technical features disclosed in each embodiment of the present invention are not limited to that embodiment, and, unless they are mutually incompatible, the technical features disclosed in each embodiment may be combined and applied to different embodiments.

Therefore, each embodiment will focus on explaining each technical feature, but unless each technical feature is incompatible with each other, it can be applied in combination with each other.

The present invention is not limited to the above-described embodiments and the attached drawings, and various modifications and variations are possible from the viewpoint of those skilled in the art to which the present invention pertains. Therefore, the scope of the present invention should be determined not only by the claims of this specification but also by the equivalents of these claims.
