Technical Field

The invention relates to the field of packaging containers for products, in particular to a container closure device mounted on a container neck, a component thereof and a packaging container.

Background

In many applications, such as the mixing packaging of different materials, it is highly necessary to release each material into another material shortly before the use of the mixture of the various materials. Storing the products in a pre-mixed form is often not possible or desirable because, after a period of time when the products are stored as a mixture, they may undesirably react with each other or cause a degradation of the mixture. Common examples are, for example, two or more pharmaceutical components which have better stability and longer shelf life when unmixed than when mixed, and for mixed liquid products such as drinks, liquid pharmaceuticals, special medical use formula meal, liquid cosmetics, liquid reagents and the like, for which two or more different materials in the product need to be stored separately during the shelf life of the product in order to make it more advantageous for stability, freshness, functional assurance or other quality improvement of the product.
