Description

Container and bottle blank thereof

Technical Field

The utility model relates to a packaging container field of product specifically is to relate to a container, the container can form packaging container with assorted container closing means combination together.

The packaging container can be widely applied to the packaging of products such as medicines, drinks, drinking wine, health-care foods, formula foods for special medical purposes, common foods, medical instruments, hygienic products, cosmetics, daily necessities and the like, and is particularly suitable for the sealed packaging, storage and mixed blending of products containing liquid materials in the packaging container. The invention also relates to a packaging composition for the packaging container, a method for assembling the closure and use thereof.

Background

In many applications, such as mixed packaging of different materials, it is very necessary to discharge or release and mix the materials into the materials in the container shortly before the mixture of the various materials is used. Storing the product in a pre-mixed form is often not possible or desirable because when the product is stored as a mixture for a period of time, it can undesirably react with each other or cause the mixture to degrade. Common examples are e.g. two or more pharmaceutical components which have better stability and longer shelf life when not mixed than when mixed.

The utility model provides a can be in the same place with assorted container closing means combination to satisfy packaging container's functional need, various requirements sealed, assembly.
