  The container part of a blister pack is shape | molded according to the shape and number of articles | goods which a cup part accommodates. That is, when storing a plurality of articles in one container part, if the number of articles to be stored changes, a blister pack is manufactured using a container part having a cup part having a different shape and size according to the number. Become. For example, if the article is a cylindrical battery, a different number of cylindrical batteries, such as two, four, or eight, may be stored in the container portion even at the same size. At the blister pack manufacturing site, a plurality of types of container portions corresponding to the number of batteries are prepared, and blister packs are manufactured using the different types of container portions.

  Thus, in the conventional blister pack, unless the number of articles to be stored is specified, the container portion cannot be shared, and it is difficult to manufacture the blister pack at a lower cost. Recently, automated factories that can manufacture different types of products on a single line by sharing parts with different products have also been realized, but the shape of the container part differs depending on the number of items in conventional blister packs. Therefore, it becomes necessary to separate the production line for each product having different storage numbers, and it becomes more difficult to reduce the production cost.

  Of course, it is possible to prepare only one type of container part to store a certain number of articles and change the number of containers by arranging a plurality of container parts on the mount, but a flange part is formed around the container part. As a result, the container portions adjacent to each other on the mount are greatly separated from each other, and a larger mount is required even if the number of stored articles is the same, resulting in an increase in cost. If the container parts are largely separated from each other, the beauty when the blister pack is displayed as a product at the store is also impaired. Further, if it is attempted to reduce the width of the flange portion in order to reduce the distance between the container portions, sufficient adhesion strength between the mount and the container portion cannot be ensured. In particular, when a relatively heavy article such as a battery is stored, its own weight is always applied, and it is not preferable to lower the adhesive strength.

  Therefore, an object of the present invention is to provide a blister pack in which the number of articles can be flexibly changed and the mount and the container are bonded with sufficient strength while having high space efficiency at a lower cost.

The present invention for achieving the above object is a blister pack in which a container part in which an article is stored is bonded to one main surface side of a mount,
Two directions orthogonal to each other in the plane of the mount are defined as a left-right direction and a front-rear direction. The container portion is made of integrally molded resin, and opens to one main surface side of the mount to serve as a storage space for the article. The flange part which protrudes in the shape of a bowl toward the outside is formed in the periphery of the cup part,
A plurality of the container parts are provided, and each container part is arranged side by side in the left-right direction, the front- rear direction, or the left-right front-rear direction, and between adjacent containers, the flange parts are stacked in the vertical direction. The surface that is bonded and in contact with the one main surface of the mount in the flange portion is bonded to the mount,
It is a blister pack characterized by this. The plurality of container portions may be blister packs having the same shape.

The manufacturing method of the blister pack is also within the scope of the present invention.
Using a frame-shaped jig in which a plurality of openings corresponding to each of the plurality of container parts are opened upward,
The frame-shaped jig includes a heating means on the frame-shaped upper end surface, and opens so that each opening has a planar shape of the cup of the corresponding container portion,
In the frame-shaped jig, the frame that separates the adjacent openings has a width for laminating the flanges of the adjacent container portions when the container portions are dropped with the flange portions upward in the respective openings,
The mount is coated with a thermoplastic adhesive on the one main surface,
In the state in which the article is stored inside the cup portion of each of the plurality of containers, the cup portion of each container portion is dropped into the corresponding opening portion in the frame-shaped jig, whereby the plurality of containers are removed from the frame. A container mounting step to be mounted on the jig,
The flange portion is mounted by the heating means while placing the mount on the plurality of container portions in a state where the main surface is directed downward and mounted on the frame-shaped jig, and pressing the mount downward. And an adhesive step in which the region in contact with the mount in the flange portion is bonded by the thermoplastic adhesive and the stacked regions are welded to each other by heating the mount and the mount The blister pack manufacturing method is characterized.

  The blister pack according to the present invention can flexibly change the number of articles stored. In addition, the mount and the container are bonded with sufficient strength while having high space efficiency. It can also be provided at a lower cost. And according to the manufacturing method of the blister pack of this invention, the blister pack of this invention can be manufactured efficiently.

In any case, between the adjacent container parts (10-10), it is only necessary that the flange parts 12 are bonded in a laminated state. Of course, the shape of the mount 20 is not limited to a rectangle.

=== Production Method of Blister Pack ===
Next, as a method of manufacturing the blister pack according to the embodiment of the present invention, a manufacturing procedure of the blister pack 1a shown in FIGS. FIG. 6 shows an outline of the production method. FIG. 7 shows the flow of the manufacturing method. As shown in FIG. 6, in order to manufacture the blister pack 1 a according to the embodiment of the present invention, two container parts 10 and a mount 20 having the same shape and a battery 30 to be stored in the container part 10 are prepared. A frame-shaped jig having openings 41 corresponding to the number of the parts 10 (hereinafter also referred to as a frame-shaped jig 40) is prepared. In addition, the container part 10 used here shape | molds a film-like PET (polyethylene terephthalate) resin with a well-known vacuum foam. The mount 20 has a front surface 21 coated with a thermoplastic adhesive. In the following description of the manufacturing procedure, the vertical direction is defined with the back surface 23 side of the mount 20 as the upper side. About the parallel direction of the two container parts 10, it is set as the left-right direction as mentioned above.

  The frame-shaped jig 40 is constructed by laying a heating wire 43 such as a nichrome wire along the peripheral shape of the opening 41 on the upper surface of a frame-shaped base 42 in which openings 41 aligned in the left-right direction are formed above. . In this example, a frame-shaped flat plate (hereinafter also referred to as a frame-shaped sheet 44) made of a fluororesin or the like and opened in the same planar shape as the opening 41 is attached to the base 42, and the heating wire 43 is It is sandwiched between the upper end surface of the base 42 and the frame-like sheet 44. Thereby, in the area | region which circulates the opening part 41 in the upper surface 46 of the frame-shaped jig | tool 40, the heat | fever generate | occur | produced in the linear heating wire 43 will generate | occur | produce on a surface. A lead wire 45 for supplying electric power to the heating wire 43 is led out of the base 42. Of course, a ribbon-like heater may be laid on the upper end surface of the frame-shaped jig 40. In the illustrated example, guide pins 47 for aligning the mount 20 with its outer shape are implanted around the upper surface 46 of the frame-shaped jig 40.

  Next, each part of the frame-shaped jig 40 will be described in more detail. The upper surface shape of the opening 41 is the same as the planar shape of the cup portion 11 in the container portion 10, and the frame body 48 that separates the adjacent opening portions 41 is used. The width w1 substantially coincides with the width w2 of the flange portion 12 (w1≈w2).

  Next, the flow of the manufacturing method according to the embodiment will be described in the order of (A) to (E) of FIG. First, two container parts 10 are prepared (A), and the battery 30 is accommodated in the cup part 11 of each container part 10 (B).
