DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blister pack container comprising a combination of a mount and a plastic molded product.

[0002]

2. Description of the Related Art A transparent plastic sheet is formed into a shape substantially the same as the contents by vacuum molding, and the contents are housed between the plastic molded product thus produced and a backing sheet, and the two are sealed by, for example, heat sealing. BACKGROUND ART Blister pack containers having a structure to be adhered have been often used for packaging various kinds of products, because the contents can be easily seen from the side of a plastic molded product and the product has a display effect.

[0003] Further, as described in, for example, Japanese Utility Model Application Laid-Open No. 1-94269, for the purpose of stably holding stored goods and improving designability,
A blister pack container has also been proposed in which a plastic molded product containing a product is sandwiched between two mounts.

[0004]

By the way, recently, from the viewpoint of ecology and the like, various systems for collecting and recycling after using packaging materials such as packaging materials for transportation and merchandise sales have been considered. In some countries (for example, Germany), government ordinances have been enacted that require product manufacturers and retailers to collect and recycle packaging materials. Therefore, in consideration of such recycling, in the case of a composite container such as the above-mentioned blister pack container, it is desirable that the composite container can be separated and collected for each material after the use of the packaging material. However, in the above-mentioned conventional blister pack container, since the mount and the plastic molded product are firmly bonded to each other by heat sealing or the like, peeling does not occur at the interface between the mount and the plastic molded product, and peeling occurs between layers of the mount. However, there is a problem that it is very difficult to completely separate these two.

Although the above publication discloses a plastic molded product sandwiched between two mounts, the publication also discloses that the mount is plastically welded to the plastic molded product. The present invention has been made in view of the above problems, and easily separates a mount and a plastic molded product in a blister pack container. The purpose is to be able to.

[0006]

According to the present invention, there is provided a blister pack container comprising a mount, a plastic molded product having a convex portion for accommodating contents and a flange portion provided on the periphery of the convex portion. A blister pack container comprising a combination, wherein the mount is composed of a front-side mount and a back-side mount, and a punching hole is provided in the front-side mount, and a convex portion of a plastic molded product is fitted into the punching hole to form a flange-like portion. Is sandwiched between the backing sheet and the backing sheet, so that the front sheet and the backing sheet do not cover the flange section outside the flange section.
