Finally, the lid plate 16 is bent along the bending line 25 and the insertion piece 17 is inserted inside the side plate 11, thereby positioning the stored item holding portion 46 having the article holding hole 47 at a predetermined height from the bottom surface. A bottom structure in the open state is obtained.

In this state, the space between the first fold line 41 and the second fold line 42 and the space between the third fold line 44 and the fourth fold line 45 located on both sides of the stored article holding portion 46. Are set to be equal to each other, the stored item holding portion 46 is in a state parallel to the lid plate 16 on the bottom surface. Further, since the locking piece 48 is sandwiched between the inner lid plate 18 and the lid plate 16, the stored item holding portion 46 can be reliably held at a predetermined position.

On the other hand, in the opening on the upper side, after the first stored item holding piece 33 is bent toward the inside of the case by the first folding line 31, the first folding line 32 is further extended to the first folding line 32.
The tip of the stored item holding piece 33 is bent in a direction toward the lower opening. Bending at the portion of the second bending line 32 is because the bending line 32 is formed in an arc shape, so that the first stored item holding piece 33 is bent toward the tip side of the bending line 32 and inside the case. A restoring force is generated in the direction of coming into contact with the side surface of the stored article.

The stored article holding pieces 33 are brought into contact with each other, and the bottom of the article 51 is fitted into the article holding hole 47. Therefore, since the bottom of the article 51 is held in the article holding hole 47 of the second stored article holding piece 43 and the body is held by the first stored article holding piece 33, the article 51 is smaller than the case body 10. Even when 51 is stored, the article 51 can be reliably held in the case.

That is, padding is put in the case,
Since a small article 51 can be stored in a case of a desired size without providing an article holding member, it is possible to improve the appealing effect of the article at the time of display at the store and the risk of theft. Is also significantly reduced.

As shown in the above-described embodiment, by providing the article holding hole 47 in the second stored article holding piece 43 to hold the bottom of the article 51, the width and depth of the case body 10 can be made smaller than that of the case body 10. An article having a small part size can be held at a predetermined position in the case. However, if the width and depth dimensions of the case body 10 correspond to the body size of the article 51, the article holding hole 47 is provided. You don't have to. Depending on conditions such as the shape and weight of the article 51, the article 51 may be stored in the case only by providing the first stored article holding piece 33 on the upper side without providing the second stored article holding piece 43 on the bottom side. It can be held in position. In this case, the bottom side of the case may have a normal bottom structure, for example, a hell bottom. Further, although the above-mentioned form example illustrates the hanging case, a normal box-shaped case can be similarly formed.

[0019]

As described above, according to the plastic case of the present invention, even when a small article is stored in a case formed by folding one plastic sheet,
Since it is possible to store the article while securely holding it in a case of a desired size without the need for another member,
A larger case can be used compared to the article. As a result, the display effect at the time of display at the store is improved, the product can be positively appealed to contribute to the sales promotion of the product, and it is also effective for the theft prevention measures for small articles.
