Description

The present invention molds a synthetic resin sheet that stores eggs such as raw eggs, boiled eggs, hot spring eggs, smoked eggs, fruits, fruits and vegetables, miscellaneous cargo, etc., and hangs them for display and sale. Regarding thin-walled containers for packaging.

As shown in FIG. 6, the thin-walled container disclosed in Patent Document 1 below and exhibited and sold by suspending one or a small number of conventional items includes a body portion 1, a lid portion 2, and these two portions 1. It is composed of a hinge portion 3 for flexibly connecting 2 and 2 and tongue pieces 7 and 8 for suspending, and a synthetic resin sheet is integrally molded by vacuum forming or blow molding.

The flange 11 of the body portion 1 is formed with ridges 12 all around, and the flange 21 of the lid portion 2 is formed with a step portion 22 that fits with the ridges 12 of the body portion 1.

When an item is put in the body portion 1 and the lid portion 2 is closed and hung, the tongue pieces 7 and 8 are formed continuously on the flanges 11 and 21 of the body portion 1 and the lid portion 2 which correspond to the apex. When the body portion 1 and the lid portion 2 are closed, the tongue pieces overlap to form a round hole. As shown in FIG. 6, one is a hook-shaped tongue piece 7 and the other is a protrusion. The tongue piece 8 is illustrated.

As shown in FIG. 7A, Patent Document 2 below discloses a tongue piece 7 having the same shape and a hook shape. When the body portion 1 and the lid portion 2 are closed, as shown in FIG. 7B, the tips of the tongue pieces 7 overlap to form a horizontally long round hole 6.

When the item is put in the thin-walled container configured in this way and closed, the ridge 12 of the body part 1 and the lid part 2 are closed.
The step portion 22 of the above is fitted and does not open carelessly.

However, since the tongue piece is made by molding a synthetic resin sheet, it is difficult to deform in the direction parallel to the surface of the sheet, but it is easy to bend in the direction orthogonal to the surface of the sheet.

Therefore, when a thin-walled container that is heavy with goods is hung on a bar using a round hole formed by overlapping tongue pieces, it is stable when the tongue pieces are orthogonal to the bar. However, as shown in the perspective view of FIG. 8, when the container rotates and the tongue piece 7 intersects the bar 71 at an angle, the bar 71 expands the two overlapping sheets and gaps between the tongue pieces. The rod material 71 may enter the gap and drop the thin-walled container.

In order to solve the problem that the tongue pieces open and fall when the thin-walled container containing the goods is hung and exhibited and sold, it is conceivable to make round holes in each of the two tongue pieces.

However, the manufacturing process of a thin-walled container for molding a synthetic resin sheet includes a molding process in which the sheet is heated and softened and continuously molded into the shape of the container by vacuum forming or blow molding, and the molded container. It has undergone a punching process to complete a thin-walled container by punching the entire circumference of the container.

In order to make a round hole, a drilling process is required in addition to the molding process and the punching process, which causes a problem that the manufacturing cost becomes high. Furthermore, when the round hole is punched out, the debris scatters and becomes dust, so care must be taken when disposing of the debris.

Despite the problems to be solved for the thin-walled containers for hanging, displaying and selling, there was still a request to utilize them in order to effectively utilize the three-dimensional space of the sales floor.

The thin-walled container of the present invention is a thin-walled container in which a body portion, a lid portion, and a hinge portion for flexibly connecting the body portion and the lid portion are integrally formed, and when the thin-walled container is closed and suspended. To,
A pair of tongue pieces are formed on each side of the body part and the lid part corresponding to the top, and when the lid is closed, the pair of tongue pieces overlap to form a hole and form a hole in the overlapping part of the tongue pieces. A hook portion consisting of a fitting convex portion and a fitting concave portion is formed.

According to the thin-walled container of the present invention, a hook portion consisting of a fitting convex portion and a fitting concave portion is provided on a pair of tongue pieces forming a hole through which a bar material is inserted, and the tongue pieces are fixed to each other. The pair of tongue pieces does not open and fall. This hook portion can be molded at the same time in the molding process of the thin wall container, and does not require a drilling process for inserting the bar material, so that the manufacturing cost is not increased.
