Description

  The present invention relates to a packaging container, and more particularly to a packaging container referred to as a so-called blister container.

  Conventionally, a blister container is known as a packaging container. A blister container is composed of a container part made of a transparent resin and a mount (substrate part) for fixing the container part, and is often used as a container for various objects to be packaged such as a toothbrush and a dry battery. (For example, refer to Patent Document 1).

  Since this blister container has a good display effect because the packaging container packaged from the outside can be seen, it can be expected to increase the customer's willingness to purchase the packaged items when displayed at the store. For this reason, recently, blister containers are frequently used as cosmetic packaging containers.

  7 and 8 show a general blister container 1 (packaging container) disclosed in Patent Document 1. FIG. The blister container 1 has a battery 4 as an object to be packaged. As shown in FIG. 7, the blister container 1 is roughly composed of a blister part 2 and a mount 3.

  The blister part 2 is made of a transparent resin, and is formed with a storage part 5 for storing the battery 4 and a collar part 6 for fixing to the mount 3. The mount 3 is made of paper, and a product name or the like is printed on the surface thereof, and a synthetic resin film is formed on the surface. Then, after the battery 4 is mounted in the storage portion 5, the blister portion 2 is attached to the mount 3 by thermally welding the collar portion 6 of the blister portion 2 to the synthetic resin film formed on the mount 3 using a heating tool. The battery 4 is packaged in a blister container 1 as shown in FIG.

In addition, the blister container 1 having this configuration has a problem that the fixing force of the heat-welded portion between the blister part 2 and the mount 3 is strong, and it is troublesome to take out the battery 4 from the blister container 1. For this reason, for example, a blister container has been proposed in which the mount can be slidably mounted on the blister part as disclosed in Patent Document 2, thereby improving the take-out property of the package.
