Cap assembly for beverage container {CAP ASSEMBLY FOR BEVERAGE CONTAINER}

The present invention relates to a cap assembly for a beverage container, and in particular, improves the coupling structure between the cap member of the beverage container and the container stopper, so that the cap member can be capped without separating the cap member from the container stopper when the container stopper is opened according to the user's desired choice. It relates to a cap assembly for a beverage container with an improved structure so that the member and the container cap can be rotated together to open the container cap from the container body or to separate the cap member from the container cap.

In general, most liquid products in the fields of beverages, medicines, chemicals, etc. are manufactured by mixing all various ingredients, and then the liquid product is injected into containers such as glass bottles, plastic bottles, jars, etc. and sealed with a stopper. It is sealed and distributed and sold.

Recently, a functional bottle cap structure has been proposed that has an inner cap member for adding additives into the container, allowing additional additives (coffee, vitamins, etc.) to be added to the contents contained within the container.

In particular, since vitamins are very sensitive substances that are easily destroyed when exposed to heat or light, great care must be taken when storing and handling vitamin drinks. Therefore, the container containing the vitamin beverage is a brown bottle made of thick glass, which has a relatively excellent light blocking and insulating effect to prevent destruction of vitamins by light or heat. However, the shelf life or exposure time to the outside is prolonged. If it increases, the effectiveness of preventing vitamin destruction decreases.

In addition, when a drink is manufactured by mixing all ingredients, including vitamins, vitamins can be easily destroyed not only by external factors such as heat and light, but also by internal factors caused by ingredients other than the vitamins mixed in the drink. there is.

Therefore, in order to prevent the premature destruction of these vitamins, vitamins are not mixed during the production of beverages, but beverage products are produced and sold with additives such as vitamins stored in the container cap, just before the consumer drinks the beverage. A container stopper that can minimize the destruction of vitamins by putting the vitamins stored in the container stopper into the container has been developed and used.

The prior art related to the butt cap includes a lower cap that surrounds the inner cap member and is coupled to the inlet part of the container, a gasket part that is fixedly coupled to the bottom of the lower cap and seals the lower part of the inner cap, and an upper cap that is screwed to the top of the lower cap. There was a technique that included absence.

However, in the case of the conventional bottle cap, a separate gasket part is required to fill the inner cap with additives and then seal the lower part, so there is a problem in that the number of parts increases, resulting in an increase in the manufacturing process and manufacturing cost.

In addition, in the case of the gasket part coupled to the lower side of the inner cap, there was a problem of moisture leaking through the side of the coupling groove when used for a long time because it was coupled into a single watertight structure using a single coupling groove.

In addition, since the inner cap that connects to the gasket portion and the lower cap member is made of the same hard synthetic resin material as the lower cap member, it reacts sensitively to temperature and pressure changes and when the shape is deformed, the additive inside the inner cap becomes moisture and deteriorates. There was this.

Therefore, there is an urgent need for a realistically applicable bottle cap technology that can improve the sealing power of the inner cap that accommodates the additive and reduce manufacturing costs by reducing the number of parts and simplifying the manufacturing process.

The prior art of the bottle cap related to this is as disclosed in Korean Patent Publication No. 10-1525196 "Buttle cap and bottle cap manufacturing method" (registration date: 2015.05.27), which includes a container for containing additives added to the container. an inner cap formed in a rod shape with a space inside and an open lower part; A lower cap that surrounds and accommodates the outer periphery of the inner cap and is coupled to the inlet of the container, and has a watertight coupling portion inside which is coupled to the lower part of the inner cap in a multiple interference fit method to form a multi-watertight structure; And the upper cap is fixedly coupled to the upper end of the inner cap and screwed to the upper part of the lower cap.

The watertight coupling portion is formed by extending the inner side of the lower cap into the interior of the container, has an outlet on the side for discharging additives, and has a main body formed in a cylindrical shape that entirely surrounds the circumference of the inner cap; And a packing protrusion that protrudes upward from the lower bottom surface of the main body and is coupled to the lower inner surface of the inner cap in an interference fit manner.

In addition, other prior art related to container closures includes a lower body coupled to the inlet of the container and having a through hole, as disclosed in Korean Patent Publication No. 10-1528199, “Container Cap” (registration date: 2015.06.05) ; and an upper cap coupled to the lower body and having an additive receiving space therein, wherein the lower body includes an outer lower member having threads formed on an inner peripheral surface so as to be screwed to a thread on an outer peripheral surface of the inlet portion of the container, and the outer lower member. An inner lower member disposed concentrically and inserted into the inlet of the container, the outer lower member and an upper member extending upward from the inner lower member and having a thread formed on the outer peripheral surface, the center at the inner circumference of the lower end of the inner lower member It includes a bottom portion formed to be inclined downward in a conical shape, a through hole formed in the center of the bottom portion, and a plurality of arch-shaped through slots formed concentrically with the through hole at an inner circumference of the lower end of the inner lower member of the bottom portion. and; The upper cap includes an outer member having a thread formed on an inner peripheral surface so as to be screwed to a thread on the outer peripheral surface of the outer upper member of the lower body, a cylindrical member disposed concentrically with the outer member and inserted into the inner lower member of the lower body, and It is disposed in the center and includes a cylinder member formed in the shape of a cylindrical pillar; The lower end of the cylindrical member of the upper cap is sealingly coupled to the through hole of the lower body, and the lower end of the cylindrical member of the upper cap sealingly closes the plurality of through slots of the lower body.

However, the existing container cap structure simply stores additives such as ginseng powder, coffee, and vitamins within the container cap and only has an injection function to inject the additives into the interior of the container at the same time as the container cap is opened. Since the container stopper is opened by turning the container stopper in one direction after separating the member from the container stopper, the cap member and the container stopper must be opened separately to open the container stopper, and after opening is completed, the container stopper and the cap must be opened again. There is the inconvenience of having to assemble each member individually.

Korean Patent Publication No. 10-1525196 “Buttle cap and bottle cap manufacturing method” (Registration date: 2015.05.27) Korean Patent Publication No. 10-1528199 “Container Cap” (Registration Date: 2015.06.05)
