Description

[DESCRIPTION]

[Invention Title] BOTTLE CAP

[Technical Field]

The present invention relates to caps, and more particularly, to a container cap that can discharge an additive from a storing member through discharging holes of the storing member as an opening member is lifted up and opened, where an easy peel film body is fused and bonded to the lower end of a cylindrical short plate, which allows the opening plate to be opened and closed, and separated from the short plate when the outer surface contacts the lower end of the inside tube of the storing member as the short plate is lifted up, thereby preventing humidity from permeating and providing an easy separation.

[Background Art]

In general, container caps serve to close and open containers containing contents. In recent years, container caps have been developed to store additional additives therein and add them to contents of the container when they are opened.

Figure 1 is an exploded perspective view depicting a conventional container cap. Figure 2 is a perspective view depicting the cap of Figure 1 coupled to a container. Figure 3 is a cross-sectional view illustrating the cap of Figure 2, before coupling to a container. Figure 4 is a cross- sectional view illustrating the cap after coupling to a container. Figure 5 is a cross-sectional view illustrating the cap in use.

The conventional cap includes a storing member 200, an opening member 300 and a detachable valve 400. The storing member 200 forms an inner-thread 213 on the inner wall thereof, which is tightly coupled to an outer-thread 112 formed at a general container 100 so that the contents cannot leak out from the container 100. The storing member 200 also forms an outer-thread 230 on the outer wall thereof, which is coupled to an inner-thread of the opening member 300. The storing member 200 also forms an inside protrusion 224 on the outer periphery at the upper end thereof, and has discharging holes 212 formed in the center axis direction. A locking part 272 or a locking gear is formed below the discharging holes 212.

The inside protrusion 224 serves to prevent the opening member 300 from being separated therefrom when the container is operated, and instead to gear the opening member 300 with the storing member 200, lifting up the storing member 200 together when the opening member is continuously rotated and lifted up.

The discharging holes 212 are formed at the lower end of the storing member 200. Numerous discharging holes 212 are required to ensure efficient usage. They serve to provide passages through which an additive is discharged from the opening member 300 to the container 100.

The locking part 272 allows the detachable valve 400 to be tightly coupled and fixed thereto, so that it provides a force that separates the lower end of the opening member 300 from the detachable valve 400 when the container 100 is used. The locking part 272 is shaped with a sloped upper edge side which is cut off, and this makes the detachable valve 400 easy to enter but not to detach therefrom.

The opening member 300 forms an inner-thread 322 on the inner wall of the outside part thereof, so that the inner-thread 322 can be coupled to the outer-thread 230 of the outer wall of the storing member 200. The opening member 300 also forms a cylindrical short plate 310 on the center portion in the axis direction to protect a receiving part 210. The short plate 310 forms a sealing groove 328 on the lower surface of the end thereof.

The sealing groove 328 is tightly coupled to a sealing protrusion 428 formed in the detachable valve 400 to prevent the additive W2 in the receiving part 210 from leaking when the container 100 is stored or carried.

The detachable valve 400 is shaped in such a way that: the sealing protrusion 428 is formed on the upper portion close to the outer periphery thereof to couple to the sealing groove 328; a locking groove 427 is formed on the outer wall at the middle height! and an entering shaft 425 is formed at the end thereof.

The locking groove 427 allows the locking part 272 and locking gear of the storing member 200 to be tightly locked thereto so that the detachable valve 400, having been lowering together with the opening member 300 when the container is used, can be tightly fixed to the storing member 200.

The entering shaft 425 is shaped as a cylinder form whose inside is hollow and whose outer diameter is tapered downward, and this shape makes the detachable valve 400 having been lowering easy to lock to the locking part 272. In particular, the entering shaft 425 is hollow to allow the entering shaft 425 to be slightly bent in the center axis when the entering shaft 425 enters the locking part 272.

Unlike the method for opening a general container in the counterclockwise direction, when the opening member 300 is rotated slightly in the clockwise direction, it is lowered down, which makes the detachable valve 400 lower down too. The opening member 300 lowers until it contacts the upper end of the storing member 200. Simultaneously, the detachable vale 400 having been lowered is also fixed to the storing member 2000 as the locking part 272 of the storing member 200 is tightly fitted into the locking groove 472 of the detachable valve 400.

After that, when the opening member 300 is rotated in the clockwise direction, the opening member 300 is separated from the detachable valve 400 and lifted up alone. When the lower portion of the opening member 300 starts to open, the additive W2 is discharged through the discharge holes 212 of the storing member 200.

When the opening member 300 continues to lift up, its inner-thread 322 is locked by the inside protrusion 224 of the storing member 200, so that the storing member 200 can be also lifted up and thus a user can use the contents Wl mixed with the additive W2, immediately and easily.

The receiving part 210 is filled with the additive and then sealed by the detachable valve 400. This series of processes may be conducted in an additive filling factory and then the intermediate products can be carried to a beverage production factory. In addition, there is another method where the opening member 300, filled with the additive and sealed by the detachable valve 400, is entered and fixed to the lower end portion of the locking part 272 or locking gear of the storing member 200 and then sold on the market. Therefore, consumers purchase a container with this type of opening member and just rotate it in the counter-clockwise direction to open it.

Although the conventional method allows the additive to be added to the contents of the container, when a powder type additive is contained in a plastic member, the plastic member allows humidity to permeate the plastic and thus the powder-type additive may become lumpy, which makes it difficult to be added to the contents of the container or causes the product to spoil.

There is another conventional container cap as shown in Figure 6. It is configured to include a storing member 200, an opening member 300, and a detachable valve 400. The storing member 200 is coupled in a screw manner to the opening of a container 100. The storing member 200 has an inside tube 215, located inside the opening of the container 100, whose inner bottom is opened, forming a storing space. The opening member 300 is coupled in a screw manner to the upper end portion of the storing member 200. The opening member 300 has a short plate 310 that is extended through the inside tube 215 and is exposed from the end of the inside tube 215. The detachable valve 400 closes the lower end opening of the short plate 310 and forms an edge that is expanded to contact the lower end of the inside tube 215. The detachable valve 400 forms a detachable groove 401, coupled to the end portion of the short plate 310, and a valve edge 402 outside the detachable groove 401.

The conventional cap is assembled as follows: the short plate 310 of the opening member 300 is fitted into the inside tube 215 of the storing member 200; the bottom of the short plate 310 is upward; an additive fills the exposed storing space; and the exposed short plate 310 is coupled to the detachable valve 400 as it is fitted into the detachable groove 410 of the detachable valve 400.

After that, the conventional cap caps a container 100. When the opening member 300 is rotated and lifted up, the valve edge 402 contacts the end of the inside tube 215 and thus the lifting operation of the detachable valve 400 is stopped. Accordingly, the end of the short plate 310 is separated from the detachable groove 401. This conventional cap can simply add the additive to the contents of the container since the detachable valve 400 is separated from the opening member 300. It has, however, disadvantages in that the separated detachable valve 400 may enter the user's mouth while the user drinks the contents of the container and causes discomfort to user. In particular, when children drink contents of the container with this type of cap, the separated detachable valve 400 causes a choking hazard for danger to choke the children as the valve can block their respiratory tract. Furthermore, since the detachable valve 400 is made of polyethylene or polypropylene, it can be easily permeated by humidity. Therefore, when a powder-type additive is stored in the storing member, the detachable vale causes the additive to become lumpy and deteriorates an addition function or more worse prevents the additive from being added to the contents of the container.

[Disclosure]

[Technical Problem]

Therefore, the present invention has been made in view of the above problems and provides a container cap that has an easy peel film body that completely closes the lower end side of an opening member and thus prevents humidity from permeating, in which the opening member receives an additive and closes and opens its bottom.

The present invention further provides a container cap, according to another aspect of the present invention, which has an easy peel film body that completely seals the lower end side of a tube type short plate that forms an opening member, in which the easy peel film body is greater than the outer diameter of the short plate and the inner diameter of an inside tube of a storing member so that it can be easily separated therefrom when the opening member is separated and lifted up, thereby storing an additive without permeating humidity and allowing the additive to be added to the contents of the container only when it is used.

The present invention provides a container cap, according to a fourth aspect of the present invention, which has an easy peel film body the exposed portion of an edge of which is hooked to an hook of the lower end of the inside tube when the easy peel film is separated, thereby providing users with convenience.

The present invention provides a container cap, according to a fifth aspect of the present invention, which is configured in such a way that a thin easy peel film body is fused and bonded, by a high frequency fuse- bonding method, to the lower end of an short plate of an opening member so that the easy peel film body can couple the fuse-bonded opening member and a storing member and then be capped, thereby enhancing the capping operation, watertightness and a storage function of an additive.

The present invention provides a container cap, according to a sixth aspect of the present invention, which is configured in such a way that a storing member is fitted into the opening of a container, which is the same form as the general container, thereby reducing users' discomfort, and an easy peel film body is not separated therefrom but fixed thereto, thereby enhancing usability and users' access to the container.

The present invention provides a container cap, according to a seventh aspect of the present invention, which is configured in such a way that an opening member couples its short plate to an additional sealed storing container for a storing member, which is made of glass, ceramic, or synthetic resin, etc., thereby expanding its use range to a variety of fields, such as medical containers, baby food containers, etc.

The present invention provides a container cap, according to a eighth aspect of the present invention, which is configured in such a way that an additional container is used and the upper end of the additional container is loosely coupled to the coupling groove formed on the side at the upper end inside the opening member, so that the additional container is just lifted up when the opening member is rotated and thus the rotational force of the opening member is reduced, which makes it easy for even a children to use.

The present invention provides a container cap, according to a ninth aspect of the present invention, which is configured in such a way to include an aluminum foil body serving as an easy peel film body, so that it can be applied to highly sterilized products to which an easy peel film body is difficult to be applied. The container cap may be further achieved by an aluminum foil body that is coated with a functional material, which has a variety of functions. [Technical Solution]

In accordance with an aspect of the present invention, the container cap includes^ a storing member for storing an additive, having discharging holes in the side at the lower end portion thereof; an opening member having an short plate for discharging the additive as the short plate closes or opens the discharging holes of the storing member; a detachable valve that is coupled or uncoupled to a bottom of the opening member; and an easy peel film that is coupled to the opening member in such a way to warp an lower end of the short plate and the diameter of its outside end portion is greater than that of the short plate. A lower end of an inside tube, forming a portion of the discharging holes of the storing member, is located at above the easy peel film body.

Preferably, the easy peel film body includes: a coupling part that is fused and bonded with the lower end surface of the short plate; and an exposed part that is exposed to the outside from the outer diameter of the short plate and is exposed in such a way to be greater than the inner diameter of the inside tube of the opening member when the opening member is lifted up. Here, the exposed part may be separated from the inside tube or fused and bonded to the lower end of the inside tube. The easy peel film is not separated but hooked to the inside tube by a hook shaped as the outer diameter of the lower end of the inside tube is increased.

Preferably, the easy peel film body includes: an easy peel film that is easily fused and bonded thereto and whose fuse-bonded portion (M) is easily separated from a portion other than the fuse-bonded portion (M); and a base film that supports the easy peel film so that only the fuse-bonded portion of the easy peel film can be separated therefrom.

Preferably, the easy peel film body is replaced with an aluminum foil body. The aluminum foil body includes: aluminum foil; and an adhesive layer that is coated on the surface of the aluminum foil and exerts a hot-melt adhering function. [Advantageous Effects]

As described above, since first to third embodiments of the present invention are operated in such a way that the peripheral edge portion of an easy film body, which has been closing the short plate of the opening member, contacts the lower end of the inside tube of the storing member and is stopped when the opening member is lifted up, the lower end of the opening member is opened and simultaneously the additive is discharged through the discharging holes. That is, since the first and third embodiments can add the additive to the contents, conveniently, only when they are used, they cannot allow humidity to be permeated and thus keep the additive fresh for a relatively long period of time.

According to a fourth embodiment of the present invention, since the exposed portion of an edge of an easy peel film body is hooked to an hook of the lower end of the inside tube when the easy peel film is separated, it enhances user convenience.

According to a fifth embodiment of the present invention, since a thin easy peel film body is fused and bonded, by a high frequency fuse- bonding method, to the lower end of an short plate of an opening member, the easy peel film body can couple the fuse-bonded opening member and a storing member and then be capped, it enhances the capping operation, watertightness and storage function of an additive.

According to a sixth embodiment of the present invention, since a storing member is fitted into an opening of the container, which has the same form as the general container, it reduces users' discomfort. Also, since an easy peel film body is not separated therefrom but fixed thereto, it enhances usability and users' access.

According to a seventh embodiment of the present invention, since an opening member couples its short plate to an additional sealed storing container for a storing member, which is made of glass, ceramic, or synthetic resin, etc., it expands its use range to a variety of fields, such as medical containers, baby food containers, etc.

According to a eighth embodiment of the present invention, since an additional container is used and the upper end of the additional container is loosely coupled to the coupling groove formed on the side at the upper end inside the opening member, the additional container is just lifted up when the opening member is rotated and thus the rotational force of the opening member is reduced, which makes it easy for even a children to use.

According to a ninth embodiment of the present invention, since an aluminum foil can serve as an easy peel film body, it can be applied to highly sterilized products to which an easy peel film body is difficult to be applied. This also may be achieved by aluminum foil that is coated with a functional material, which has a variety of functions. [Description of Drawings]

Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 7 is a cross-sectional view illustrating a first embodiment of a container cap according to the present invention. Figure 8 is a cross- sectional view illustrating a second embodiment of a container cap according to the present invention. Figure 9 is a partially enlarged cross-sectional view illustrating a primary portion of the second embodiment. Figure 10 is a partially enlarged cross-sectional view illustrating the primary portion of Figure 9 that describes its use principle. Figure 11 is a cross-sectional view illustrating a third embodiment of a container cap according to the present invention.

The container cap is configured in such a way that: a storing member 200 stores an additive and has discharging holes in the side at the lower end portion thereof; an opening member 300 having an short plate 310 that discharges the additive as the short plate 310 closes or opens the discharging holes of the storing member 200; a detachable valve 400 that is coupled or uncoupled to a bottom of the opening member 300; and an easy peel film 500 that is coupled to the opening member 300 in such a way to warp an lower end of the short plate 310 and the diameter of its outside end portion is greater than that of the short plate 310. Here, the lower end of an inside tube 215, forming a portion of the discharging holes 212 of the storing member 200, is located at above the easy peel film body 500.

The easy peel film body 500 is configured to include: a coupling part 510 that is fused and bonded with the lower end surface of the short plate 310; and an exposed part 520 that is exposed to the outside from the outer diameter of the short plate 310 and is exposed in such a way to be greater than the inner diameter of the inside tube 215 of the opening member 300 when the opening member is lifted up. 1

The easy peel film body 500 is configured to include: an easy film 501 that is easily fused and bonded and allows a portion other than the fuse- bonded portion to be easily separated; and a base film 502 that supports the easy peel film 501 and allows only a fuse-bonded portion of the easy peel film 501 to be separated when the easy peel film 501 is separated.

Since the easy peel film has a humidity permeating function, a container is fused and bonded with a part of the cap to prevent humidity from permeating the contents in the container. Therefore, the storing period of a cap is extended from about 1 month to 6 months or 1 year. Considering this feature of the easy peel film, it is applied to the present invention. In the present invention, it is formed within a cap, in a vacuum formation, to receive an additional force for separation.

The container cap according to the present invention employs commercial easy peel films, which are disclosed in Korean Patent Nos. 10- 0450386, 10-0581547, 10-0563479 and 10-0691399. It is preferable that the easy peel film according to the present invention is made of a resin disclosed in Korean Patent Nos. 10-0563479 and 10-0581547, which has a good adhesive property with polypropylene or polyethylene. However, it should be understood that the present invention is not limited to the resin.

The base film 502 of the present invention is configured to form a single layer or multi-layers using a variety of polymers, such as polyethylene terephthalate (PET), polypropylene, polyethylene, etc. It may further include an additional layer that exerts a function (heat resistance, watertightness, gas screening, etc.).

The principle of using the additional layer is described in Figure 10. Since the easy peel film 501 of the easy peel film body 500 is fused and bonded to the lower end surface of the short plate 310, by a high frequency fuse-bonding method, and coupled thereto by a fuse-bonded portion M, they are sealed to each other. Therefore, the easy peel film 501 is watertight.

In order to use, when the opening member 300 is rotated and lifted up, the exposed part 520 of the easy peel film body 500 is locked by the lower end of the inside tube 215, so that the lower end exerts a force to stop the lifting of the easy peel film body 500. In that case, as shown in Figure 10, the short plate 310 is separated from the easy peel film 501 and thus the easy peel film and the base film 502 remains at the position. Accordingly, the additive passes through the lower space of the opened short plate 310 in the direction of the arrow and is discharged through the discharging holes 212.

In the present invention, in order to increase the bonding force between the easy peel film body 500 and the short plate 310, the easy peel film body 500 is coupled to the lower end surface of the short plate 310 by placing a fuse-bonded portion M therebetween (embodiment 2 of Figure 8). Also, the easy peel film body 500 is coupled to the lower end surface of the short plate 310 by placing a fuse-bonded portion M therebetween and warps a portion of the inner side of the short plate 310 (embodiment 3 of Figure 11). In addition, the easy peel film body may be coupled to the short plate 310 by warping only a portion of the outside of the fuse-bonded portion M located at the lower end portion of the short plate 310 (embodiment 1 of Figure 7).

Furthermore, as shown in Figure 7, if the lower end of the inside tube 215, which is shaped as a ring and supports the lower end of the discharging holes, is uneven and the corresponding exposed part 520 is also uneven, the easy peel film body 500 can increase its bonding force. In that case, the separation can be easily performed and thus the easy peel film body can be thin.

Figure 12 is a cross-sectional view illustrating a fourth embodiment of a container cap according to the present invention. The easy peel film body 500 is bonded, by a high frequency fuse-bonding method, to the lower end of the short plate 310 of the opening member 300. A hook body 217, protruding outward, is formed at the lower end of the inside tube 215. The hook body 217 is not warped by a middle coupling part 510 of the easy peel film body 500 but by an exposed part 520 of an edge of the easy peel film body 500. Although a fuse-bonded portion M is formed at the lower end of the short plate 310, it may be additionally formed at the bottom surface of the hook body 217.

In that case, when the opening member 300 is rotated and lifted up, since the fuse-bonded portion is easily separated therefrom according to the characteristic of the easy peel film body, the additive contained in the short plate 310 can be easily discharged through the discharging holes 212 into the container 100. Since the exposed part 520 as the edge of the easy peel film body 500 is coupled to the hook body 217 by wrapping it, the easy peel film body 500 does not fall into the container 100.

Figure 13 is a cross-sectional view illustrating a fifth embodiment of a container cap according to the present invention. Figure 14 is an enlarged cross-sectional view illustrating a primary portion of the firth embodiment of Figure 13.

The container cap is configured to include: a storing member 200 that is coupled in a screw manner to an opening of a container, forms a storing space as its inner portion located in the opening of the container is hollow, and has an inside tube 215 forming a vertical slit groove 216 that is formed as its side is partially cut and exerts an elastic force; an opening member 300 that is coupled in the screw manner to the upper end of the storing member 200 and has a short plate 310 that is extended through the inside of the inside tube 215 and exposed from the end of the inside tube 215; a coupling part 510 fused and bonded to a lower end of the short plate 310 to close a lower end of the short plate 310; and an easy peel film body 500 forming an exposed part 520 that is extended from the coupling part 510 so that its edge contacts a lower end of the inside tube 215. Here, the easy peel film body 500 is formed as an easy peel film 501 is bonded on a base film 502. The lower end of the short plate 310 forms a fuse-bonded portion M when it is fused and bonded to the easy peel film 501 by a high frequency fuse-bonding method.

Unlike the conventional cap of Figure 6, the fifth embodiment of the present invention has advantages in that it uses an easy peel film body 500, the easy peel film body 500 is fused and bonded thereto in a high frequency fuse-bonding method, it can be formed in a vacuum formation method since the easy peel film body 500 is thin, such as a unit of micrometer. Figure 13 shows a cap where an easy peel film body 500 is fused and bonded thereto by a high frequency fuse-bonding method. Although Figure 13 exaggerates the easy peel film body 500, it should be understood that it is thin. An additive is inserted into the short plate 310. The easy peel film body 500 is fused and bonded thereto by a high frequency fuse-bonding method. When the short plate 310 is fitted into the inside tube 215 of the storing member 200, the slit groove 216 exerts a tension thereto. Therefore, the fifth embodiment provides an easy assembling method and guarantees watertightness.

When the opening member 300 is rotated to use the cap, the short plate 310 integrally formed with the opening member 300 is lifted up and the fuse-bonded portion M bonded to the easy peel film 501 is separated from the lower end of the short plate 310 and lifted up too. Therefore, the easy peel film body 500 is lowered down and simultaneously the additive is added into the container through the lower portion of the short plate 310.

Figure 15 is a cross-sectional view illustrating a sixth embodiment of a container cap according to the present invention. The sixth embodiment is similar to the fifth embodiment of Figure 13 except that the storing member 200 is hooked to the opening of the container 100, the opening member 300 presses the storing member 200 and simultaneously is directly coupled in a screw manner to the opening of the container 100.

The storing member 200 is configured to include: a coupling hook 281 coupled and fixed to an opening of the container 100; a cylindrical inside tube 215 that is connected to the coupling hook 281 and placed inside the opening of the container 100; discharge holes 212 that are formed at a lower end portion of the cylindrical inside tube 215 at a certain distance; a hook part 217 that is formed at a lower end of the cylindrical inside tube and protrudent outward in the radial direction; and a hook groove 218 for fixing an exposed part 520 on the outside upper end of the hook part 217. The sixth embodiment has advantages in that, since the storing member 200 does not have an additional means for supporting the opening member 300 but instead is just coupled to the opening of the container 100, the appearance is the same as a conventional container cap. It is also advantageous in that, since the easy peel film body 500 is fixed to the hook body 217, the separated cap does not enter the user's mouth. The fuse-bonded portion M makes it easy to separate the easy peel film body 500 and the short plate 310, thereby providing convenient usage to users. In addition, since the cap uses the easy peel film body which has superior watertightness, it can maintain a constant storing ability. For example, the cap can store even a powder-type additive in a constant storing condition.

Figure 16 is a cross-sectional view illustrating a seventh embodiment of a container cap according to the present invention. The seventh embodiment is modified from embodiments 1 to 6 in such a way to close a lower end portion of the short plate 310 using an easy peel film body 500. More specifically, the short plate 310 is filled with an additive and then the easy peel film body 500 is fused and bonded by a high frequency fuse-bonding method to the end part of the short plate 310. That is, the short plate 310 is formed to allow for a hook coupling. For example, the short plate 310 is able to be hooked with an additional container 330 and fixes it thereto.

The additional container 330 is configured to include: a body 333 that is shaped as a cylindrical form and forms a space for receiving an additive; a protrudent coupling wheel 334 for closing an upper end of the body 333 and hooking the short plate 310; and an easy peel film body 500 for closing an lower end of the body 333 by a high frequency fuse-bonding method. The easy peel film body 500 includes a coupling part 510 for closing a lower end of the body 333; and an exposed part 520 that is exposed to the outside of the coupling part 510 and placed at a position adjacent to the lower end of the inside tube 215. The easy peel film body 500 is formed as a base film 502 and an easy peel film 501 are bonded to each other, which is similar to embodiments 1 to 6. Also, the shape of the easy peel film body 500 can be variously modified as described in embodiments 1 to 6.

Figure 17 is a cross-sectional view illustrating an eighth embodiment of a container cap according to the present invention. The eighth embodiment is similar to the seventh embodiment of Figure 16 in that an additional container 330 is used except for the following point. That is, in the eighth embodiment, the additional container is associated with the opening member 300 in such a way that it idles regardless of the rotation of the opening member 300 and moves only up and down. That is, the eighth embodiment includes an additional coupling head 331 and a protrudent sealing wheel 332 at the upper end portion of the additional container 330. The additional coupling head 331 is protrudent to have a diameter greater than that of the inside tube 215. The protrudent sealing wheel 332 is vertically extended from the lower surface of the additional coupling head 331 to seal the upper end of the inside tube 215.

In the eighth embodiment, the short plate 310 is protruded toward the center to form a coupling groove 311 having an extra space that allows the additional coupling head 331 to be coupled to the inner wall at the inside upper end of the opening member 300. The easy peel film body 500 is fused and bonded to the lower end of the body 333 by a high frequency fuse-bonding method, which is the same as embodiment 7. Although the opening member 300 is rotated, since the additional container 330 idles, the opening member 300 can be easily opened without any additional force. Also, the additional container 330 receives only a lifting force to separate a fuse-bonded portion M of the easy peel film body 500 therefrom, allowing it to be opened. In embodiments 1 to 3 of the present invention, the opening member 300 is rotated by a vector force, whose direction is upward, which is generated as a rotational horizontal force and a lifting vertical force are added. In embodiment 8, since the opening member 300 and the additional container 330 having been idling are not rotated but only lifted up, the rotational force is hardly needed and thus the cap can be operated by a relatively small amount of force. In particular, the eighth embodiment includes an additional coupling head 331 and a protrudent sealing wheel 332 at the upper end portion of the additional container 330, in which the additional coupling head 331 is protrudent to have a diameter greater than that of the inside tube 215 and the protrudent sealing wheel 332 is vertically extended from the lower surface of the additional coupling head 331 to seal the upper end of the inside tube 215. Therefore, when the cap is coupled thereto, it always exerts a sealing operation. When the cap is opened as the opening member 300 is rotated, it is also instantly lifted up as the additional container 330 and the additional coupling head 331 are lifted up. Therefore, the frictional force exerted by the opening of the container is removed and thus the cap can be easily operated by a relatively small amount of force.

The ninth embodiment is implemented with metal foil instead of an easy peel film body. It is preferable that the metal foil is made of aluminum. The aluminum foil has an area to cover a short plate 310 or a lower end of a body 333 and to allow its outer area to reach a portion of inside tube 215. The aluminum foil body according to the present invention is implemented with aluminum foil. It should be understood that the present invention is not limited to aluminum foil. For example, the present invention may be implemented with a multi-layer stack fabricated by metal foils and synthetic resin. In that case, it has various properties such as heat- resistance, watertightness, air-permeability, antibiosis, etc., which makes applicable to a variety of uses, such as a heat-resistance bottle, pouch bottle, etc. The aluminum foil body 550 of the present invention is configured to include aluminum foil 551 and a hot-melt adhesive layer 552 coated on the surface of the aluminum foil 551. The aluminum foil 551 may be variously formed, however, it is preferable that the aluminum foil 551 is 40-50 μm thick. The hot-melt adhesive layer 552 may be implemented with a commercial hot-melt adhesive that can be fused and bonded. It is preferable that the hot-melt adhesive layer 552 is 2~3 μm thick. The hot-melt adhesive layer 552 may further form a synthetic resin polymer layer of 2-3 μm thick, which is made of polyethylene terephthalate, etc., on its one surface to repel humidity. This additional coating may be performed according to the user's request or the characteristic of product. When performing an additional coating, the inside tube 215 must tightly close the lower end of the body 333 (short plate 310), which makes it easy to separate the aluminum foil body 550 from the lower end of the short plate 310 by the force supporting the lower end of the inside tube 215 when the short plate 310 is lifted up.

In embodiment 7 of Figure 16 and embodiment 8 of Figure 17, the opening member 300 and the additional container 330 are individually installed thereto. Therefore, if the additional container 330 is made of glass, heat-resistance material, ceramic, and special synthetic resin for antibiosis in order to achieve a certain purpose and other elements, such as the opening member 300 and the storing member, are made of general synthetic resin, the manufacturing costs can be reduced and assembling work can also be easily performed. In that case, the manufacturing process can be achieved individually using various materials. Therefore, the present invention can be used for a variety of fields, for example, a medical product, a children's product, a special purpose, etc.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
