Description

This invention molds synthetic resin sheets that are used for storing and suspending and selling eggs such as raw eggs, boiled eggs, hot spring eggs, smoked eggs, fruits, fruits and vegetables, sundries, etc. It relates to a thin-walled container for packaging.

As disclosed in the following Patent Document 1 and shown in FIG. 6, a conventional thin-walled container that displays and sells one or a small number of items is a body part 1, a lid part 2, and these two parts 1. 2 and a tongue portion 7 and 8 for hanging, and a synthetic resin sheet is integrally formed by vacuum molding or blow molding.

On the flange 11 of the body part 1, a ridge 12 is formed on the entire circumference, and on the flange 21 of the lid part 2, a step portion 22 is formed that fits with the ridge 12 of the body part 1.

  When an article is put in the body part 1 and the lid part 2 is closed and hung, the tongue parts 7 and 8 are continuously formed on the body part 1 and the flanges 11 and 21 of the lid part 2 which are in contact with the top part. This tongue piece overlaps to form a round hole when the body part 1 and the lid part 2 are closed, and as shown in FIG. 6, one is a bowl-like tongue piece 7 and the other is a protrusion. What is the tongue piece 8 is illustrated.

Patent Document 2 listed below discloses a tongue-like shape in which both tongue pieces 7 have the same shape as shown in FIG. When the body part 1 and the lid part 2 are closed, as shown in FIG. 7B, the end portions of the tongue pieces 7 are overlapped to form a horizontally long circular hole 6.

Japanese Patent No. 4038801 Japanese Patent No. 5152787 JP 2007-45495 A JP-A-7-33155

When an article is placed in a thin wall container configured in this way and closed, the ridge 12 of the body part 1 and the lid part 2
The step 22 is fitted and does not open carelessly.

However, since the tongue piece is formed by molding a synthetic resin sheet, it is difficult to be deformed in a direction parallel to the surface of the sheet, but is easily bent in a direction perpendicular to the surface of the sheet.

Therefore, when a thin-walled container that has become heavier with goods is suspended from a bar using a round hole formed by overlapping tongues, the tongue is stable when the tongues are perpendicular to the bar. However, as shown in the perspective view of FIG. 8, when the container rotates and the tongue piece 7 crosses the bar 71 obliquely, the bar 71 expands the two overlapping sheets and opens a gap between the tongue pieces. In some cases, the bar 71 enters the gap and the thin-walled container is dropped.

In order to solve the problem of tongues opening and dropping when hanging and selling thin-walled containers containing goods, it is conceivable to make a round hole in each of the two tongues.

However, the thin-walled container manufacturing process 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 molding or blow molding, and the molded container. The punching process is completed by punching the entire circumference of the container to complete the thin-walled container.

In order to make a round hole, in addition to the molding process and the punching process, a drilling process is required, and there is a problem that the manufacturing cost increases. Furthermore, when the round hole is punched out, fragments are scattered and become garbage, so care must be taken in the processing of the fragments.

In spite of the problems to be solved in the thin-walled containers for hanging and selling in this way, there is still a demand for utilizing the three-dimensional space of the sales floor effectively.

The thin-walled container according to the present invention is a thin-walled container integrally formed with a body part, a lid part, and a hinge part that flexibly connects the body part and the lid part, and the thin-walled container is closed and suspended. In addition,
A pair of tongues are formed on each side of the body part and the lid part corresponding to the top side, and the pair of tongue parts overlap to form a hole when the lid is closed, and at the overlapping part of the tongue piece The hook part which consists of a fitting convex part and a fitting recessed part is formed.

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