Description

Stoppers and containers equipped with them

The present invention relates to a stopper and a container equipped with the same. More specifically, before opening the stopper, different types of contents are accommodated separately from each other, and when the stopper is opened and the contents are consumed, different types of contents are consumed together. It relates to a stopper equipped with a barrier that allows it to be used and a container equipped with the same.

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

Among these containers, containers equipped with a functional stopper that can be accommodated separately and have a separate space separate from the inner space of the container body have been developed and are commercially available.

The separation space provided in the stopper accommodates contents (e.g., main contents) and other types of contents (e.g., secondary contents) contained in the container body.

Therefore, in order to consume the main contents contained in the container body, when the user opens the stopper coupled with the container body and ingests the main contents, the secondary contents contained in the stopper are also consumed.

However, due to problems with the 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 container body, which is mainly composed of liquid.

The problem to be solved by the present invention is to prevent mixing of the contents contained in the container body and the contents contained in the stopper, thereby extending the storage period of the two contents.

Another problem to be solved by the present invention is to easily perform the breaking operation of the stopper containing the contents using a simple structure. Another problem that the invention aims to solve is to increase user convenience by conveniently ingesting the contents of the container body and the contents of the stopper.

A stopper according to one feature of the present invention includes a stopper part coupled to a container body having an injection port, the stopper part being coupled to the container body, a side of the stopper extending from the engaging part, and extending from the side of the stopper, The upper surface of the stopper changes at least one of the inclination angle and shape due to a force applied from the outside, extends downward from the upper surface of the stopper, and moves downward according to the change in the upper surface of the stopper, with each lower end moving away from each other. It includes a plurality of damaged parts that spread out and a blocking film that faces the damaged parts and is broken by movement of the damaged parts and is divided into a plurality of split blocking parts.

As the plurality of damaged parts become farther apart from each other, the distance between adjacent split blocking parts increases, and the opening size of the injection hole blocked by the blocking film may increase in proportion to the distance between adjacent split blocking parts.

Each damaged portion may extend from a portion where at least one of the inclination angle and shape of the top surface of the stopper changes.

The top surface of the stopper may protrude upward, and when force is applied to the top surface of the stopper, the shape may be changed to protrude in the downward direction.

When at least one of the inclination angle and shape of the top surface of the stopper changes, the plurality of damaged parts may move in a diagonal direction closer to the side of the stopper.

The broken portion may include a column-shaped broken pin and a broken wing attached to the outside of the broken pin, protruding from the outside toward the side of the stopper, and extending along the longitudinal direction of the broken pin.

The protruding height of the breakage wing may increase toward the upper surface of the stopper.

The blocking film may include a cutting line that divides the blocking film into a plurality of divided areas, and each divided area may become a divided blocking portion when the blocking film is damaged.

The damaged portion may be located facing the divided area, and force may be applied to the divided area facing the divided area to damage the blocking film to create the divided blocking portion.

The barrier film may include a metal layer and a coating layer located on at least one surface of the metal layer.

The cutting line may be located within the coating layer.

At least a portion of the stopper may be formed of a resin material, and a portion of the blocking film may be located inside the resin material, and the portion may be embedded within the resin material.

The blocking film may be attached to the bottom of the side of the stopper.

The coupling portion may include a screw groove and a screw thread located on the inner surface, and when the container body is inserted between the coupling portion and a side of the stopper, the coupling portion may be screwed to the container body by the screw groove and the screw thread. .

The outer surface of the coupling portion may be an uneven surface.

The stopper according to the above feature may include an upper surface of the cover and a side of the cover connected to the upper surface of the cover and a lower part of the cover being open, and may further include a stopper cover part detachably coupled to the stopper part.

The stopper may further include a coupling protrusion protruding upward from the outer surface of the top surface of the stopper, and the stopper cover part may be located on the inner surface of the cover upper surface and further include a coupling groove into which the coupling protrusion is inserted. When at least one of the inclination angle and shape of the upper surface of the stopper changes, the engaging protrusion may be inserted into the engaging groove.

The stopper may further include a plurality of rotation blocking protrusions on the outer surface of the side of the stopper, which extend along the longitudinal direction of the side of the stopper and are positioned to be spaced apart from each other.

The stopper cover part may further include an insertion protrusion extending from the inner surface of the cover side along the longitudinal direction of the cover side and positioned to be spaced apart from each other, and when the stopper part and the stopper cover part are coupled, the insertion protrusion Can be inserted into the groove located between two adjacent rotation blocking protrusions.

It may further include a lowering obstruction portion that is positioned between the cover side surface and the coupling portion according to the above feature and prevents the closure cover portion from descending.

A container according to another feature of the present invention may include a closure according to any one of claims 1 to 20.

According to this feature, the different types of contents contained in the container body and the stopper are not mixed and are stored without quality deterioration, so the shelf life of the contents can be increased.

In addition, since the barrier film is firmly positioned on the container body, the problem of the barrier film being damaged during the distribution process can be prevented.

Additionally, since the end of the barrier film is positioned to be inserted into the container body, the oxidation phenomenon of the barrier film containing a metal material such as aluminum can be prevented from exposure to air or moisture.

In addition, since the barrier film is inserted and molded into the side of the adjacent plug, the barrier film is embedded in the side of the plug, so the connection structure between the barrier film and the side of the plug can be very simple.

Moreover, since the contents are lowered into the container body by a simple pressing operation of the damaged portion, user convenience can be greatly improved.

Additionally, since the barrier film damaged by the breakage pin moves to the outside of the stopper, the size of the inlet through which the contents present in the stopper flow into the container body may increase.

Because of this, the contents located within the stopper flow into the container body with minimal loss, so the amount of contents lost inside the stopper can be greatly reduced.

Hereinafter, a container equipped with a stopper according to an embodiment of the present invention will be described.

As shown in FIGS. 1 and 2, the container 1 of this example is provided with a stopper 100 and a coupling part 202 with a screw thread 2021 located on the outside of the side, and the cap 100 is connected through the coupling part 202. ) may be provided with a container body 200 coupled to the container.

The stopper 100 is coupled to the coupling portion 202 of the container body 200 to allow the contents (e.g., main contents) contained in the internal space (S200) of the container body 200 to the outside through the inlet 204. Leakage can be prevented.

For example, the main content accommodated in the internal space (S200) of the container body 200 may be a liquid substance.

As shown in Figures 3 to 8, the stopper 100 is a stopper 110 coupled to the coupling part 202 of the container body 200 having an injection port 204, and is located on the outside of the stopper 110. It may be provided with a stopper cover part 120 that is located and detachably coupled to the stopper part 110, and a lowering obstruction part 130 that couples the stopper part 110 and the stopper cover part 120.

The stopper portion 110 may be screwed to the coupling portion 202 of the container body 200 and may be rotated in a corresponding direction by a force applied from the outside to block or open the injection port 204.

Accordingly, the stopper 110 can block the open inlet 204 of the container body 200 to prevent the main contents contained in the container body 200 from unintentionally leaking out.

As shown in FIGS. 2 and 4, this stopper portion 110 is located on the stopper side 111, the stopper side 111, and more specifically, the top of the stopper side 111. and a stopper upper surface 112 that is seamlessly connected and has a coupling protrusion, a blocking film 113 located on the lower part of the stopper side 111, a stopper upper surface 112, and specifically a stopper upper surface 112. A damaged portion 114 extending downward from the inner surface, that is, along the longitudinal direction of the container 1, and having at least one broken pin 1141a that breaks and tears the barrier film 113, and a stopper side 111. A coupling portion 115 that is spaced apart from and coupled to the coupling portion 202 of the container body 200, a plurality of rotation blocking protrusions 116 located on the outer surface of the cap side 111, and a cap side 111. It may be provided with a blocking portion 117 located between the coupling portion 115 and the coupling portion 115.

In this example, the stopper side 111 and the stopper top surface 112 may form the stopper body of the stopper portion 110.

As shown in FIG. 4, the stopper side 111 may be positioned to extend from the coupling portion 115 and may have a circular planar shape. This stopper side 111 is open at the top and bottom and may have a cylindrical shape with an empty space inside.

Accordingly, the open upper part of the stopper 110 may be blocked by the upper surface of the stopper 112, and the open lower part may be closed by the blocking film 113.

The lower end of the stopper side 111 may be positioned to face the top of the coupling part 202 when the stopper part 110 is coupled to the coupling part 202 of the container body 200.

Due to this, the blocking film 113 located on the lower part of the side of the stopper 111 completely blocks the inlet 204 surrounded by the coupling portion 202, thereby allowing the inlet 204 located inside the container body 200 through the inlet 204. It is possible to prevent contents from flowing into the stopper 100.

As already described, the top surface of the stopper 112 may be located on the open top of the side of the stopper 111 and cover the open top of the side of the stopper 111 .

The upper part of the stopper 110 may be blocked by this stopper upper surface 112.

The stopper upper surface 112 may extend from the stopper side 111 and may be a convex surface (eg, curved surface) that protrudes from the edge of the stopper side 111 to the center.

Accordingly, the top surface of the stopper 112 is connected to the edge portion 112a and has an inclination angle (i.e., an inclination angle with the installation surface) (θ1) and a shape determined by a force applied from the outside. It may be provided with at least one driving part 112b whose state changes.

As shown in FIG. 4, the inclination angle of the edge portion 112a of the stopper upper surface 112 connected to the edge of the stopper side 111 and the inclination of the driving portion 112b in contact with the edge portion 112a The angles may be different from each other.

For example, the edge portion 112a may be a flat surface parallel (e.g., parallel) to the installation surface, while the driving portion 112b may have an inclined surface (e.g., a convex surface or a curved surface) that intersects the installation surface.

Accordingly, the driving part 112b may have an inclined surface inclined at a predetermined direction and angle with respect to the installation surface.

When the stopper upper surface 112, specifically the driving part 112b, is in its initial state, that is, when no physical force is applied to the stopper upper surface 112, it moves in an uphill direction centered on the edge portion (the first direction) (e.g., (+) direction).

This stopper upper surface 112 has a structure that descends downward centered on the edge portion 112a of the stopper upper surface 112 when a physical force is applied to the outer surface of the stopper upper surface 112 in the initial state. You can.

In this case, at least one of the inclination angle and shape of the top surface of the stopper 112, specifically the driving portion 112b, may change from the initial state to the driving state. For example, the top surface of the stopper 112 (e.g., the driving portion 112b) moves in a downhill direction (e.g., the (-) direction) opposite to the first direction (e.g., the (-) direction) around the edge portion 112a. It can change from uphill to downhill with a slope that changes both the shape and the slope angle.

In this example, the edge portion 112a may have a thickness smaller than that of the driving portion 112b, and in this case, the transformation operation (i.e., shape and form) of the driving portion 112b around the edge portion 112a An operation in which at least one of the inclination angles changes) can be performed more easily.

In this example, the top surface of the stopper 112 has an edge portion 112a and a driving portion 112b having different shapes (i.e., a flat surface and an inclined surface).

However, in an alternative example the edge portion 112a may be omitted, in which case the closure upper surface 112 may have only a driving portion 112b, which driving portion (i.e. the closure upper surface The edge of (112)) (112b) may be directly connected to the edge of the side of the stopper 111, and the upper surface of the stopper 112 may change at least one of the inclination angle and shape with the edge as the center.

As such, at least one of the shape and inclination angle of the top surface 112 of the stopper in this example may change due to a physical force applied from the outside.

In addition, in order to facilitate the position change of the stopper upper surface 112 centered on the edge of the stopper upper surface 112 and to facilitate the application of physical force, the stopper upper surface 112 is The thickness may vary depending on the location, and in this case, the thickness of the edge may be thinner than the center portion.

However, in an alternative example, the thickness of the stopper top surface 112 may be the same depending on the location, and the shape may be parallel to the installation surface rather than intersecting the installation surface (e.g., a convex surface or curved surface). It can have a flat surface.

The engaging protrusion 1121 located on the top surface of the stopper 112 may protrude from the center of the outer surface of the top surface 112 of the stopper in an upward direction, that is, toward the stopper cover part 120.

By the coupling protrusion 1121, the stopper 110 can be coupled to the stopper cover part 120, and as a result, the force transmitted from the stopper cover part 120 is applied to the upper surface of the stopper through the coupling protrusion 1121. It can be delivered to (112).

The force transmitted through the coupling protrusion 1121 changes the position of the top surface of the stopper 112, so that the upper surface of the stopper 112 moves downward around the edge toward the blocking film 113, thereby forming the upper surface of the stopper 112. Location may change.

Since the damaged portion 114 with a broken pin 1141a is attached to the inner surface of the cap upper surface 112, the damaged portion ( 114) the lowering operation can be performed. Accordingly, the blocking film 113 may be damaged by the damaged portion 114 descending toward the blocking film 113.

As already described, the blocking film 113 is located below the side of the stopper 111 and can completely block the open lower part of the side of the stopper 111.

That is, the blocking film 113 of this example is located at the lower part of the stopper side 111 and faces the damaged part 114, and as shown in FIG. 10, the damaged part 114 is damaged by the movement of the damaged part 114. It may be damaged and divided into a plurality of split blocking portions (P113).

As an example, the blocking film 113 may be a thin film having a circular planar shape that can completely block the lower part of the open side of the stopper 111.

Therefore, the inside of the stopper side of the stopper 100 that communicates with the internal space (S200) of the container body 200 is an internal space (S100) completely blocked by the stopper side 111, the top surface of the stopper 112, and the blocking film 113. ) may exist.

Because of this, the injection port 204 is not opened before the barrier film 113 is damaged or the stopper 110 is separated from the container body 200, so the main contents located inside the container body 200 are stored in the stopper 100. ) cannot flow into the

Additionally, secondary contents different from the main contents may exist in the sealed internal space (S100) surrounded by the stopper side 111, the stopper top surface 112, and the blocking film 113.

In this example, the minor contents may be in powder form or in solid state, such as in capsule form.

In this way, since there is another closed space (S100) physically separated from the internal space (S200) of the container body 200 by the barrier 113, the secondary contents are safely stored in the closed space (S100) so as not to be mixed with the main contents. It can be stored.

In this example, the blocking film 113 may contain a metal material such as aluminum.

As shown in FIG. 2, the diameter of the blocking film 113 may be larger than the diameter of the open side of the stopper 111.

Accordingly, a portion of the edge portion of the blocking film 113 may be inserted into the adjacent stopper side 111 and positioned to be buried, as shown in FIG. 2 .

For this reason, there may be a groove in the side of the stopper 111 into which the blocking film 113 is inserted, and this groove may be completely filled with the material of the side of the stopper 111. Accordingly, the blocking film 113 can be positioned in the corresponding groove of the stopper side 111 while being integrally coupled with the stopper side 111.

This blocking film 113 can be combined with the adjacent portion of the stopper 110 through an insert injection method. To this end, a part of the stopper 110 may be made of a resin material, and a part of the blocking film 113 may be located inside the part of the stopper 110 made of a resin material and embedded in the resin material.

As an example, the blocking film 113 may be inserted into a groove located at the edge of the side of the stopper 111 and then positioned and coupled to the side of the stopper 111.

Accordingly, the edge portion of the blocking film 113 may be inserted into the edge portion of the stopper side 111 and positioned integrally with the stopper side 111, as shown in FIG. 2 .

As a result, the risk of the blocking film 113 inserted into the side of the stopper 111 falling out of or leaving the groove can be greatly reduced, so the blocking film 113 can be safely and firmly positioned at the corresponding position on the side of the stopper 111. there is.

As shown in FIG. 9, the upper and lower surfaces of the barrier film 113 containing a metal material can be coated with a hygienically safe coating material to prevent oxidation, etc., and the barrier film 113 in this example is located in the middle layer. It may include a metal layer 1131 and an upper coating layer 1132 and a lower coating layer 1133 located above and below the metal layer 1131, respectively.

This barrier film 113 is formed by cutting a single barrier sheet having an upper coating layer 1132 and a lower coating layer 1133 in which the upper and lower surfaces of the metal layer 1131 are coated with a coating material, respectively, into a circular sheet having a desired diameter. It can be manufactured.

Therefore, the side of the blocking film 113, which is the cut surface, is a part where the coating material is not applied. If air or moisture comes into contact with this part where the coating material is not applied, oxidation may occur, and the metal contained in the blocking film 113 Ingredients may leak to the outside.

However, as in this example, the side of the barrier film 113 that is not coated with a coating material through the insert injection method flows into the side of the stopper 111 where it is located and is molded integrally with the side of the stopper 111, so the side of the stopper 113 It can be buried in (111). Accordingly, the side of the blocking film 113 is blocked from contact with oxygen or moisture, thereby preventing oxidation and preventing the components contained in the blocking film 113 from leaking out.

In addition, due to molding into the side of the stopper 111, the phenomenon of the barrier film 113 being separated from the side of the stopper 111 can also be prevented, and as a result, the main contents contained in the container body 200 and the stopper 100 ) can be safely stored separately.

However, in an alternative example, the barrier film 113 may be positioned to be attached to the bottom of the closure side 111 through an adhesive or heat treatment process, rather than being molded into the closure side 111. In this case, the attachment process of the blocking film 113 can be performed more easily than the molding method, and manufacturing costs can also be reduced.

In order to make it easier to damage the blocking film 113 by the damaged portion 114, the blocking film 113 of this example is cut on at least one of the upper and lower surfaces of the blocking film 113, as shown in FIG. 4. A line (L113) may be provided.

At this time, the depth of the cutting line (L113) is located within at least one of the upper and

lower coating layers

1132 and 1133, respectively, located at the top and bottom of the blocking film 113, or at the boundary between the coating layer and the metal layer 1131. It may be located in or within the metal layer 1131.

The cutting line L113 located on the blocking film 113 may be determined according to the position of at least one breakage pin 1141a that descends toward the blocking film 113.

For example, each breakage pin 1141a may be positioned to face a portion of the blocking film 113 where the cutting line L113 is not located.

Due to this, when each broken pin (1141a) descends and comes into contact with the blocking film 113, the broken pin (1141a) applies a physical force between the two adjacent cutting lines (L113) on the same plane, and these broken pins The pressing operation by (1141a) may cause the two adjacent cutting lines (L113) to be broken.

Accordingly, the blocking film 113 may be damaged around the cutting line L113, and the blocking film 113 may be divided into a plurality of split blocking portions P113, which are a plurality of parts cut along the cutting line L113. There is (see Figure 10).

At this time, the blocking film 113 is divided into a plurality of split blocking portions (P113) based on the cutting line (L113), so each divided area (A113) divided by the cutting line (L113) is divided when the blocking film 113 is damaged. It can be a blocking unit (P113).

At this time, the edge of each split blocking portion (P113) is still connected to the side of the stopper (111) and can remain connected to the side of the stopper (111).

The damaged portion 114 may extend in a downward direction from the top surface of the stopper 112, specifically, the inner surface of the top surface 112 of the stopper, and moves in a downward direction according to changes in the top surface of the stopper 112. The lower ends can move in a direction that spreads away from each other (see Figure 10).

As a result, the damaged portion 114 may move toward the lower blocking film 113 due to at least one of the shape change and the angle change of the top surface of the stopper 112, damaging the blocking film 113, as already described.

As already described, the damaged portion 114 is attached to at least one damaged pin 1141a that extends long toward the blocking film 113, and is attached to the outside of the damaged pin 1141a and extends along the longitudinal direction of the damaged pin 1141a. At least one connection portion 1142 may be provided to securely attach the broken wing 1141b and each broken pin 1141a to the inner surface of the top surface 112 of the stopper.

For example, as shown in FIG. 7, there may be four breakage pins (1141a), and these breakage pins (1141a) may be positioned facing each other and spaced apart from each other with the center of the top surface 112 of the stopper as the center. there is.

The shapes of the breakage pins 1141a are the same, and as shown in FIGS. 7 and 8, as an example, they may have a pillar shape with various cross-sectional shapes such as approximately triangular, circular, or oval.

As shown in Figure 8, in the cross-sectional shape of the breakage pin (1141a), each breakage pin (1141a) may have two hypotenuses and one base, and the two hypotenuses connected to each other are connected to the stopper side 111. It may be toward the center of the enclosed space, and the base connected to these two hypotenuses may be located toward the outside, that is, toward the side of the stopper (111).

The breakage wing 1141b of each breakage pin 1141a is located on the bottom adjacent to the side surface 111 of the stopper and may extend toward the upper surface 112 of the stopper along the longitudinal direction of the breakage pin 1141a.

At this time, the protrusion height of the damage wing (1141b) protruding from each bottom side toward the side surface 111 of the stopper may increase toward the upper surface 112 of the stopper.

In this example, the cutting line L113 located on the same side of the blocking film 113 has two cutting lines L113 that intersect each other at 90 degrees, and the blocking film 113 is cut by these two cutting lines L113. ) can be divided into four areas and can be provided with four divided areas (A113).

At this time, each broken pin (1141a) can be positioned facing each split area (A113), which is a blocking portion between the cutting lines (L113), as already described, so that each cutting line ( L113) may be located correspondingly.

For this reason, as already described, when the breakage pin (1141a) descends, each breakage pin (1141a) contacts each divided region (A113) and then pushes the adjacent divided region (A113) in the downward direction, as shown in Figure 10 The barrier film 113 is damaged along the cutting line L113 as shown.

In this example, since at least one of the inclination angle and shape of the stopper upper surface 112 changes due to the applied force, when the stopper upper surface 112 is lowered due to a change in the position of the stopper upper surface 112, , the direction of movement of each damaged portion 114 attached to the upper surface 112 of the stopper can also be changed. In this example, each damaged portion 114 may descend while moving in an inclined direction (i.e., diagonal direction) toward the side of the stopper 111 instead of descending in a direction perpendicular to the installation surface.

Therefore, the angle θ2 of the breakage pin 1141a according to this example with respect to the installation surface (e.g., the ground) may be changed from the initial state when lowered, and the angle θ2 may be approximately 90 degrees in the initial state. (see Figure 2) and may be at an angle greater than 90 degrees when descending (see Figure 11).

In this way, so that the breakage pin (1141a) can move toward the side of the stopper (111), each breakage pin (1141a) is a part ( For example, it may be located in the driving part) (112b).

For this reason, when the blocking film 113 is damaged by the breakage pin 1141a, the split blocking portion P113 divided into a plurality of pieces (for example, four) is broken by the breakage pin 1141a on the stopper side 111. ) may be damaged while being pushed toward the side, and at this time, the split blocking portion (P113) can be moved closer to the side of the stopper (111) by the breakage wing (1141b) located adjacent to each stopper side (111).

In this example, as the plurality of damaged portions 114 become farther apart from each other, the distance between the adjacent split blocking portions (P113) may increase, and the opening size of the inlet 204 that was blocked by the blocking film 113 may be determined by the adjacent split blocking portions. (P113) can increase in proportion to the distance between them.

At this time, the protrusion height (H1) of the breakage wing (1141b) may increase toward the upper surface of the stopper (112). In this case, as the breakage pin (1141a) descends toward the container body 200, the breakage wing (1141b) The split blocking portion (P113) divided by can be moved much more easily and smoothly toward the outer side of the stopper (111).

Due to the downward direction of the breakage pin (1141a), the breakage operation of the barrier film 113 can be performed more smoothly, and the split cutoff portion (P113), which is divided into a plurality of pieces by the breakage action, is not simply broken but is instead a stopper. A change in position may occur where the position is moved further toward the side 111.

By moving the position of the split blocking portion (P113), the open area of the inlet 204 that was blocked by the blocking film 113, that is, the area that is completely open and not covered by the split blocking portion (P113), is simply opened by the blocking film 113. It can increase significantly compared to the damaged case.

Due to this increase in open area, the secondary contents located in the internal space (S100) within the side of the stopper (111) can more easily and quickly move toward the container body (200) and are blocked by the split blocking portion (P113). The amount of secondary contents that cannot move toward (200) can be greatly reduced.

Compared to the case where the stopper upper surface 112 is a flat surface parallel to the ground, when the stopper upper surface 112 is a convex surface convex toward the top, when the breakage pin 1141a is lowered, the stopper upper surface 112 is centered on the edge. As a result, the amount of descent can be much larger.

Therefore, compared to the case of a flat surface, not only the descending length of each broken pin (1141a) descending in a diagonal shape, but also each broken pin (1141a) that is spread in a diagonal direction moving in a diagonal direction toward the stopper side 111. The amount of movement can also increase significantly.

Accordingly, the divided split blocking portion (P113) also moves toward the side of the stopper (111) due to an increase in the amount of movement in the diagonal direction of each breakage pin (1141a), thereby further reducing the effect of opening the inlet (204) that was blocked by the blocking film (113). It can be improved further.

The connection portion 1142 of the broken portion 114 is connected to the corresponding protruding broken pin 1141a attached to the inner surface of the cap upper surface 112 and then extends toward the edge of the cap upper surface 112. ) can be located on the inner surface of the

By this connection portion 1142, the attachment area of the damaged portion 114 attached to the inner surface of the upper surface 112 of the stopper increases, so that each damaged portion 114 is stably attached to the inner surface of the upper surface 112 of the stopper. It can remain attached to.

The coupling portion 115 may be positioned spaced apart from the side of the stopper 111 and may be coupled to the coupling portion 202 of the container body 200.

In this example, the coupling portion 115 has a circular planar shape like the side surface 111 of the stopper, and may have an approximately truncated cone shape that is empty inside and whose diameter increases toward the bottom.

Additionally, the coupling portion 115 may be exposed to the outside even when the closure portion 110 and the closure cover portion 120 are coupled. Accordingly, the user can open or close the injection port 204 of the container body 200 by applying force to the externally exposed coupling portion 115 and rotating the coupling portion 115 in a desired direction.

This coupling portion 115 may have a screw thread 1151 located on the inner surface and a screw groove between the screw threads 1151.

The screw groove and thread 1151 of the coupling part 115 can be screwed to the coupling part 202 of the container body 200, so that the container body 200 and the stopper 100 can be screwed together. there is.

Accordingly, the coupling portion of the container body 200 is inserted into the empty space between the outer surface of the closure body and the coupling portion 115 by the coupling portion 115 positioned spaced apart from the closure body, specifically the side surface 111 of the closure. A portion of 202 is inserted so that the stopper 110 can be normally screwed to the coupling portion 202 of the container body 200.

The outer surface of the coupling portion 115 may have a concave-convex surface in which concave portions and convex portions are alternately located. At this time, an example of the concave portion and the convex portion may each have a long shape in the vertical direction. However, instead of the uneven surface of the coupling portion 115, it may have a flat surface.

When the coupling part 115 has a concavo-convex surface, the user can more easily perform a rotation operation of the coupling part 115.

The plurality of rotation blocking protrusions 116 located on the outer surface of the stopper side 111 may extend long along the longitudinal direction of the stopper side 111 from the coupling portion 115 toward the top surface 112 of the stopper.

As shown in FIGS. 4 and 5 , the plurality of rotation blocking protrusions 116 may be positioned along the outer peripheral surface of the stopper side 111 to be spaced apart by a predetermined distance.

These rotation blocking protrusions 116 improve the user's grip when the user rotates the stopper body, allowing the user to perform the rotation of the outer portion more easily and conveniently.

In addition, the plurality of rotation blocking protrusions 116 perform an opening or closing operation of the stopper 100 by rotating the stopper cover 120 while the stopper cover 120 is coupled to the stopper 110. When doing so, it can perform a function of transmitting the force applied to the stopper cover part 120 to the stopper part 110.

Therefore, the function of the rotation blocking protrusion 116 allows the closure portion 110 to rotate in the same direction as the rotation direction of the closure cover portion 120.

As shown in FIGS. 4 and 5, the rotation blocking protrusion 116 may not be located on the top of the stopper side 111, but in contrast, each rotation blocking protrusion 116 is located at the top of the coupling portion 115. Rotating blocking protrusions 116 that extend to the top of the stopper side 111 without interruption or have a predetermined length may be positioned periodically (e.g., in the form of a dotted chain line) along the longitudinal direction of the stopper side 111.

Referring to Figures 2 and 5, the blocking portion 117 is located between the stopper side 111 and the coupling portion 115, and serves to close the gap between the stopper side 111 and the coupling portion 115. can do. By this blocking portion 117, the coupling portion 115 can be coupled to the outer surface of the side surface 111 of the stopper.

Therefore, the blocking portion 117 may have a circular band shape with an empty center, and the width of the blocking portion 117 may be determined according to the separation distance between the stopper side 111 and the coupling portion 115. there is.

The position of the blocking part 117 can be determined according to the insertion length of the coupling part 202 inserted between the stopper side 111 and the coupling part 115, so that the blocking part 117 is connected to the stopper side 111 and the coupling part 115. It may be located at a designated portion between the coupling portions 115 (eg, the upper portion of the coupling portion 115).

By this blocking portion 117, the engaging portion 115 can be stably coupled to the side of the stopper 111, and blocks the space between the side of the stopper 111 and the engaging portion 115 to prevent moisture or dust from entering the stopper. Contamination of the interior of (100) can be prevented.

The stopper cover 120 may be inserted into the stopper 110 and cover the stopper 110 from the outside of the stopper 110 .

As shown in FIGS. 4 and 5, the stopper cover portion 120 may have a cover upper surface 121 and a cover side 122 connected to the cover upper surface 121.

Accordingly, the stopper cover portion 120 of this example may have its upper and side parts closed and its lower part open by the cover top surface 121 and the cover side surface 122, respectively.

In addition, depending on the shape of the truncated cone-shaped stopper 110, the stopper cover part 120 may also have a truncated cone shape with an empty interior.

At least one insertion protrusion 1222 may be formed on the inner surface of the cover side 122 for coupling with the rotation blocking protrusion 116 of the stopper 110.

In this example, the number of insertion protrusions 1222 is plural, and the plurality of insertion protrusions 1222 are positioned along the inner surface (i.e., inner peripheral surface) at a predetermined distance from the inner surface of the circular cover side 122. can do. Each insertion protrusion 1222 may extend along the longitudinal direction of the stopper cover portion 120.

This insertion protrusion 1222 is located on the outer surface of the coupling portion 115 of the stopper 110 and can be inserted between the vertical grooves facing each other, that is, between the grooves between the two corresponding rotation blocking protrusions 116. .

For this reason, the rotation blocking protrusions 116 located on both sides of one insertion protrusion 1222 may be vertical protrusions that function to block the rotation of only the stopper cover portion 120.

Due to this rotation blocking protrusion 116, the stopper cover 120 can move in the vertical direction (i.e., the longitudinal direction of the stopper 110) and be coupled to or released from the stopper 110.

In addition, when the stopper cover 120 is coupled to the stopper 110 and the stopper cover 120 is rotated in a predetermined direction, the rotational force is generated by physical engagement between the insertion protrusion 1222 and the vertical groove. It is transmitted to the stopper 110 and the stopper 110 along with the stopper cover 120 can be rotated in the corresponding direction.

For this reason, even in the state of being coupled to the stopper 110 without separately separating the stopper cover part 120, the stopper cover 120 is rotated so that the stopper 100 is coupled to the coupling part 202 of the container body 200. ) can be released.

When the stopper cover part 120 and the stopper part 110 are coupled to each other, the engaging groove 123 located on the inner surface of the cover upper surface 121 and the engaging protrusion located on the outer surface of the upper surface of the stopper 112. (1121) can be positioned to face each other on opposite sides, and the coupling protrusion 1121 can be inserted into the coupling groove 123, so that the cap portion 110 and the cap cover portion 120 can be coupled. As an example, a portion of the coupling protrusion 1121 may be inserted into the coupling groove 123.

The lowering obstruction part 130 is located between the lower part of the stopper cover 120 and the coupling part 115 of the stopper 110 to prevent the unwanted lowering movement of the stopper cover 120. By combining the portion 120 and the stopper portion 110, more specifically, the coupling portion 115, the stopper cover portion 120 can be prevented from being unintentionally separated from the stopper portion 110.

This lowering obstruction part 130 can be removed by the user, and may have a circular band shape connected between the lower end of the stopper cover part 120 and the upper end of the coupling part 115.

At this time, in order to facilitate the removal operation by the user, the lowering obstruction part 130 may be provided with a handle 131. Accordingly, the user can hold the handle 131 and disconnect the lowering prevention unit 130 in the corresponding direction (eg, counterclockwise).

The size of the vertical width of the descent hindering portion 130 may be determined according to the length of the coupling protrusion 1121 inserted into the coupling groove 123, so that the coupling protrusion 1121 is equal to the size of the vertical width of the descending hindering portion 130. ) is inserted into the coupling groove 123 to achieve stable coupling with the coupling groove 123.

When this lowering hindering part 130 is coupled between the stopper cover part 120 and the stopper 110, even if a physical force is applied to the cover upper surface 121 of the stopper cover part 120, the lowering preventing part 130 The lowering motion of the stopper cover portion 120 may be blocked by 130 .

Therefore, in the lowering motion of the stopper cover 120 due to the force applied to the stopper cover 120 during the transport process, etc., the stopper 110 also falls, resulting in unwanted damage to the barrier film 113 due to the damaged part 114. Movement may be prevented.

As a result, the lowering motion of the stopper 110 is not performed unless the lowering obstruction part 130 is removed by the user, and damage to the blocking film 113 that safely separates the main and secondary contents can be prevented. there is.

Accordingly, in order to consume the main and secondary contents contained in the container, the user may first remove the lowering obstruction portion 130. At this time, the user can grab the handle 131 and pull it in a designated direction to remove the lowering obstruction portion 130.

In order to damage the blocking film 113 after the descent hindering part 130 is removed, the user may apply force to the upper surface of the stopper cover part 120.

Due to the application of this force, as the insertion protrusion 1222 inserted into the coupling groove 123 moves in the direction in which the force is applied (e.g., downward direction), the stopper cover portion 120 moves toward the container body 200. It can move, that is, descend, and by this lowering motion of the stopper cover part 120, the coupling groove 123 can be coupled to the coupling protrusion 1121 protruding on the outside of the stopper part 110.

After the coupling groove 123 located on the stopper cover 120 and the engaging protrusion 1121 located on the stopper 110 are coupled, force is continuously applied to the cover upper surface 121 of the stopper cover 120. In this case, the force applied to the cover upper surface 121 of the stopper cover part 120 may also be applied to the stopper upper surface 112 of the stopper part 110.

Therefore, the top surface 112 of the stopper 110 can descend around the edge, and the height of the top surface 112 of the stopper 112 changes due to the lowering of the top surface 112 of the stopper 110, That is, due to the lowered height, the damage pin 1141a located on the inner surface of the top surface 112 of the stopper may also descend and damage the blocking film 113.

At this time, the breakage pin (1141a) moves in a diagonal direction while descending, so that the split blocking portion (P113) that is broken and divided based on the cutting line (L113) effectively moves toward the side of the stopper (111), thereby forming the inlet (204). The opening area can be increased.

At this time, since the top surface of the stopper 112 has a convex surface (e.g., a curved surface), compared to the case where it has a flat surface, the amount of movement of the split blocking portion (P113) in the diagonal direction increases, so that the split blocking portion (P113) It can be moved closer to the side (111).

When the barrier film 113 is damaged by the lowering motion of the breakage pin 1141a, the secondary contents contained in the stopper 100 pass through the open barrier film 113 and the inlet 204 and flow into the container body 200. It can be.

Accordingly, the user can shake the container to mix the main contents in the container body 200 and the secondary contents introduced from the stopper 100.

Then, the user rotates the stopper cover 120 coupled with the stopper 110 in the corresponding direction, or removes the stopper cover 120 and rotates the stopper 110 in the corresponding direction. By removing 110, the injection port 204 of the container body 200 is exposed, so that the main and secondary contents mixed together can be consumed.

According to this embodiment, the blocking film 113 blocking the lower end of the stopper 100 is damaged using a force applied from the outside, so that the secondary contents located in the stopper 110 enter the container body 200. By allowing the inflow, user convenience is improved and the structure of the container can be simple.

In addition, when the blocking film 113 is damaged, the divided blocking part P113 may move outward, and as a result, the opening amount of the inlet 204 of the container body 200 through which the secondary contents flow increases, thereby increasing the divided blocking part P113. The amount of content lost can be greatly reduced.

Moreover, since the blocking film 113 is installed by embedding it in the side of the stopper 111 through the insert injection method, the blocking force between the internal space (S200) where the main contents are located and the sealed space (S100) where the secondary contents are located can be increased. This allows the separation of the blocking film 113 to be reduced.

Because of this, the possibility that the main contents and secondary contents are undesirably mixed with each other during the distribution process can be greatly reduced, and the risk of the contents being exposed to the side where the metal layer 1131 is exposed can be prevented.
