Description

[Detailed description of the invention] This invention relates to a container for storing chiyocolate, caramel, etc.

This type of container, explained with reference to FIG. 1, consists of a combination of an outer box 1 with a rectangular frame shape in cross section and an inner box 2 with an opening at the top that is inserted into the outer box 1.
After inserting the inner box 2 into the outer box 1, it is necessary to devise a way to prevent the inner box 2 from slipping out. Conventionally, as a means for this purpose, as shown in FIG. A locking hole 4 corresponding to 3 is formed, and when the inner box 2 is pulled in the direction of the arrow and is about to come out, the locking piece 3 fits into and engages with the locking hole 4 as shown in the figure. A structure has been devised to prevent the box 2 from slipping out. However, in this method, when the inner box 2 is filled with items such as chocolate, the locking hole 4
It often happens that the upper surface is blocked and the locking piece 3 does not fit smoothly into the locking hole 4, causing the inner box 2 to fall out.

This invention focuses on the fact that the area near the inner surface of the inner box 2 is not blocked by stored items, and solves the above problem by forming locking pieces and locking holes on the side surfaces of the outer and inner boxes. The purpose is to

Hereinafter, this invention will be explained in detail based on the accompanying drawings showing one embodiment thereof.

As shown in FIG. 1, the container of this invention consists of a combination of an outer box 1 having a rectangular frame shape in cross section and an inner box 2 with an opening at the top that is inserted into the outer box 1. A locking hole in which a locking piece 3 is formed on the inner surface and stands obliquely in the insertion direction (arrow direction), and the locking piece 3 is fitted into a surface of the inner box 2 that corresponds to the inner surface of the side of the outer box 1. 4 was formed.

In the case of the embodiment, the side piece of the outer box 1 is extended, and the extending piece 5 is folded back inward to form the locking piece 3 at the tip of the extending piece 5, and the width t of the locking piece 3 is Locking hole 4
The width of the extension piece 5 is narrower than the width T of the extension piece 5.
t' is made wider than the width T of the locking hole 4. Therefore, the stepped portions of the locking piece 3 and the extending piece 5 are locked to the edge of the locking hole 4. The formation positions of the locking piece 3 and the locking hole 4 may be appropriately set depending on the amount of protrusion of the inner box 1, and the locking piece 3 may be attached separately. Further, as shown in the figure, by bending the locking piece 3 further outward in the middle, it is effective to fit into the locking hole 4 even more smoothly.

The structure of this invention is as above, and the outer box 1
When the inner box 2 is pulled out in the direction opposite to the arrow in FIG. 1 with the inner box 2 stored in the holder, the locking pieces 3 have erect kinks due to bending, so as shown in FIG. The tip of the locking piece 3 enters the locking hole 4, and the edge of the locking hole 4 engages with the stepped portion of the locking piece 3, as shown in FIGS. Further withdrawals will be blocked. During this action, the inner box 2
Since the area near the inner surface of the housing is rarely blocked by stored items, the locking piece 3 smoothly enters the locking hole 4 and is securely prevented from coming off.

As described above, according to this invention, it is possible to provide a container in which the inner box is reliably prevented from falling off without exposing the retaining mechanism on the outer surface of the outer box, which is of great practical significance.
