Description

  The present invention punches a sheet formed of a highly transparent plastic into a predetermined shape, folds it along a folding ruled line formed on its surface, assembles it into a polyhedron, and stores and sells cosmetics, daily necessities and other articles The present invention relates to a packaging case made of a plastic sheet suitable for use in exhibitions, and to a configuration that can be applied to an automatic box making machine and a packaging machine.

Cosmetics such as foundations, lipsticks, mascaras, and perfumes that women often carry in their bags are filled in beautifully designed cosmetic containers made of plastic or glass, and wrapped in a transparent packaging case. They are displayed and sold on display shelves at retail stores.
Such cosmetics often have cosmetic containers designed according to the sales image of the product, and depending on the form of the cosmetic container, for example, as shown in FIG. In this state, there is a space between the cosmetic container 101 and the inner surface of the case, so that the cosmetic container 101 moves up and down and left and right during transportation, damages the container surface, lowers the product value, and the cosmetic container 101 tilts. In some cases, the cosmetics are biased inside the container to deteriorate the quality, or the cosmetic container 101 is displayed while being tilted on the display shelf, and the appearance of the product may be deteriorated.

In order to prevent the movement of the cosmetic container in the packaging case, conventionally, a positioning tray having a recess on the surface is formed separately from the packaging case, and this is stored in the packaging case together with the cosmetic container. The cosmetic container is fixed in the recess of the positioning tray.
Further, as shown in FIG. 11, a plurality of inward projections 111 are formed along the outline of the article housed in the front and back side plates of the case 110 as a packaging case in which the article can be fixedly housed inside the case. There is known a configuration in which the inner protrusion 111 supports the article stored in the case 110 so that the article is held in the storage position (see, for example, Patent Document 1).
