Description

  The present invention relates to a blister container.

  Conventionally, in a heat-seal type blister container (blister pack), various products in which goods (container goods in which liquid chemicals, liquid cosmetics, etc. are contained in a container) are packaged by a blister container are displayed at a storefront or in a packaging box In order to improve the handling of the blister container, it is required to have a structure that can stand on its own (standing type blister container).

  As a structure that can stand by itself, it has been devised to provide a leg portion at the bottom of a bulging portion (blister dome) that accommodates an article inside. The leg is, for example, a ledge with a bottom area that can stand by itself. In the blister container, the technology of providing legs is disclosed in JP-A-9-221170 (Patent Document 1), JP-A 2003-54629 (Patent Document 2), JP-A 2007-137443 (Patent Document 3), and JP-A 2008. No. 18964 (Patent Document 4), Japanese Unexamined Patent Application Publication No. 2009-173343 (Patent Document 5), and the like.

  Here, in order to make the blister container self-supporting, it is necessary to design a low center of gravity by bringing the position of the container to be contained close to the lowermost part in order to maintain self-supporting stability.

  In order to lower the center of gravity, there is a possibility that the drop impact will be transmitted directly to the contained container article, with the contained article lowered to the lowest position, and the container may be damaged. Therefore, it is necessary to raise the bottom so that the inner container is not the lowermost part.

  It is necessary to design the bottom of the blister container so that the molded shape is not deep drawn.

  When the molding die is deep drawn, the thickness of the resin raw material is reduced (generally, there is a case where the thickness of the raw material is 300 to 400 μm and when it is deep drawn, the thickness is reduced to about 10 μm). Due to non-uniform pressure contact pressure of heat seal, seal failure or the like occurs.

  In addition, when a part of the leg portion is designed as a clog shape and can be heat sealed, deep drawing is often performed. In order to avoid deep drawing, if a flange portion for heat-sealing the lower part of the leg portion is provided, when the blister container is self-supporting, the forward tilt becomes too tight and the blister container cannot be self-supporting.

  Therefore, it has been impossible to effectively seal the legs of a conventional standing type blister container.

  Conventionally, as described above, when the leg is not sealed, a gap is formed between the dome and the mount, and the airtightness of the blister container cannot be maintained. This causes inconveniences in prevention and fouling prevention.

  As shown in FIGS. 1 and 3, the blister container according to the embodiment accommodates a vertically long article (substantially cylindrical shape such as a push-type spray container) 10 in a vertical direction. The accommodating portion 12 a bulges along the outer periphery of the article 10. And in order to support the article | item 10 stably in the accommodating part 12a, the article | item 10 is clamped by the part 12a1 dented toward the article | item 10 side, and intensity | strength is increased by the bulging part 12a2 bulging outside.

  As shown in FIG. 2, the peripheral portion 12 b of the blister dome 12 is attached to the mount 14. The central part around the article 10 is not attached, and the peripheral part 12b is mainly attached.

Examples of the resin of the blister dome 12 include, but are not limited to, PET resins such as A-PET and PETG, PP, PS, and PVC.
The mount 14 can be made of paper or resin, or a laminated sheet of resin and paper.

  The blister dome 12 is provided with a convex portion 16 for self-supporting at the lower part of the blister dome 12. The blister dome 12 is formed in a substantially semi-cylindrical shape in which the accommodating portion 12a is long in the length direction of the article 10, and the convex portion 16 is continuous with the accommodating portion 12a at the lower end portion of the blister dome 12. It is formed in a rectangular parallelepiped shape protruding in the bulging direction (vertical direction of the mount). The convex portion 16 is formed at a position where the lower end portion thereof coincides with or substantially coincides with the lower end portion of the mount 14, and the blister container can be self-supported by bringing the lower end portion of the convex portion 16 and the mount 14 into contact with a mounting surface such as a desktop. It is formed into a configuration.

  The convex portion 16 is provided with a portion 16a in which the article 10 is recessed upward and is raised at the bottom.

  In addition, the breather dome 12 is provided with a seal portion 18 at the peripheral portion 12b (which is also a peripheral portion of the mount 14) with a space between the accommodating portion 12a and a seal around the convex portion 16 adjacent to the convex portion. A portion 18 is provided. Moreover, the lower part around the convex part 16 is not sealed, and the seal part 18 is provided only on the side part and the upper part. The seal portion 18 can be formed by welding or adhesion.

  The seal portion 18 is formed in a key shape 18 a on the left and right sides of the convex portion 16 to the vicinity of the article 10 so as to wrap around from the side portion of the convex portion 16 to the upper portion.

  According to the blister container of the embodiment, the blister dome 12 is provided with a convex portion 16 for self-standing at the lower part of the blister dome 12, and the convex portion 16 has the article 10 at the bottom upward. Since the bottom-up portion 16a is provided, the article 10 can be supported by the bottom-up portion 16a when the convex portion 16 is self-supporting, and the impact is transmitted to the article 10 even if an impact is applied to the blister container. It is difficult to protect the article 10 reliably.

  Further, since the seal portion 18 is provided adjacent to the side portion and the upper portion around the convex portion 16, the adhesion of the convex portion 16 is improved, and there is no gap between the bottom portion of the blister dome 12 and the mount 14. 10 can be reliably prevented, the packaged article 10 can be prevented from falling off, and contamination can be prevented.
