Patent Application
20240101333
The present invention relates to a mixing container, and more particularly to a mixing container including a material-containing part, a bottle end, and a bottle end clamp, which is manufactured through injection molding.
Among various products which are extensively used in recent years, there are products which are intended to obtain a desired effect or a better effect when two or more kinds of components are mixed with each other and products in which two kinds of components are distributed in the state of being contained in respective containers and are mixed with each other just before use.
Examples thereof may include hair dyes for dyeing hair, injectable drugs and distilled water, liquid resins which begin to cure when mixed with a curing agent, drinkable vinegar, alcoholic beverages mixed with green plum concentrated liquid, healthy drinks containing vitamins, cosmetic products, medicines, foodstuffs and the like.
Because the above-mentioned components may immediately metamorphose or cannot be stored for a long period when mixed with each other, it is common that the components are stored and distributed in the state of being isolated from each other and are mixed with each other immediately before use.
Because such products, which are stored and distributed in the state of being isolated from each other, are distributed in the state of being contained in separate containers, there is a disadvantage in that a kind of material contained in a container must be injected into another container containing another kind of material or an additional mixing container must be used.
In order to compensate for the disadvantage, research and development of various solutions, which are intended to enable containers containing different kinds of materials to be coupled to each other so as to be mixed with each other, has been actively conducted.
As an example of the solution, there is Korea Unexamined Patent Publication No. 10-2012-0085539 (referred to hereinafter as “Patent Document 1”), which is proposed by the present applicant.
Patent Document 1 discloses a container equipped with a pair of openings, which are capable of being coupled to each other so as to allow different contents contained therein to be mixed with each other.
However, Patent Document 1 does not disclose a concrete processing method for providing the structure disclosed therein. Here, when the container having the disclosed structure is manufactured through a method such as a cutting process, there are disadvantages in that a great deal of time and effort are required and it is very difficult to apply a blowing process which is extensively used for reduction of production cost.
Furthermore, the container disclosed in Patent Document 1 uses rubber as a material of a membrane configured to seal the container to prevent the contents contained in the container from flowing to the outside. However, the container exhibits a disadvantage in that the membrane is likely to rupture so that the contents flow to the outside during distribution when the container contains, for example, a carbonated drink or beer having high internal pressure.
Accordingly, in order to solve these disadvantages, there is a need to provide a container, which is capable of reducing time and cost required for manufacture, has high pressure resistance, and is capable of being easily coupled to another container so as to allow different contents to be mixed.
The present specification refers to plural research papers and patent documents over the entire range thereof, and the citation thereof is mentioned therein. The cited research papers and patent documents are incorporated in the specification by reference in their entirety in order to more clearly explain the level of the technical field to which the present invention belongs and the contents of the present invention.
The inventors of the present invention have found that, because a conventional mixing container equipped with a bottle end is constructed such that a material-containing part and the bottle end are attached to each other through a seaming or hot melt process, the manufacturing process becomes complicated or a problem of environmental pollution caused by the hot melt process occurs. Therefore, the inventors have intensively studied in order to solve the problem. As a result, the inventors have found that, when a material-containing part is manufactured through injection molding so as to form a bottle end coupled at the lower side thereof and a bottle end clamp capable of coupling a bottle end to the material-containing part is applied, the manufacturing process becomes simple, and recycling becomes easy, thereby solving the problem of environmental pollution, and thus have achieved the present invention.
Accordingly, an object of the present invention is to provide a mixing container manufactured through injection molding.
It is another object of the present invention to provide a bottle end clamp.
Other objects and advantages of the present invention will be clearly understood from the following detailed description, claims, and the attached drawings.
