Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a plastic case for storing various types of equipment or various small items packaged in boxes.

BACKGROUND TECHNOLOGY A plastic case consisting of a case body and a lid, in which the lid can be opened and closed using a hinge, is already known, as described in Japanese Patent Publication No. 49-44112, and is used in various products. It is widely used as a case of

Problems that the invention aims to solve: A plastic case consisting of a case body and a cover body that can be opened and closed has a storage recess formed inside, and the items to be stored can be placed in the storage recess and the lid body closed. However, if you carelessly leave the case upright when opening the case, or if you open the case with the lid side facing down, the stored items may fall out of the case. As a result, there are inconveniences such as damaging the stored items and taking time to store them again.

Therefore, in view of the drawbacks of the conventional ones, the present invention has been devised to securely and firmly hold the stored items stored in the storage recess with an elastic string that stretches across the storage recess so that the stored items are always kept under tension. The object of the present invention is to provide a plastic case that has no possibility of slipping out.

Means for Solving the Problems The plastic case according to the present invention has at least one of the case body and the lid as an integral structure with a hollow double wall, and the case body or the lid as an integral structure with a hollow double wall. , larger than the entire circumference of the stored item,
A storage recess that expands in the opening direction and is lower than the height of the article to be stored is formed, and a locking hole that penetrates the hollow part of the hollow double wall structure is provided on the opposite wall surface of the storage recess, and a rod-shaped and intermediate part is provided. An elastic string member is provided with rotatable locking members attached to both ends of the elastic string member, and the tip of one of the locking members of the elastic string member is inserted into the hollow part of the case through the locking hole and rotated to lock the elastic string member. It is characterized by having the following configuration.

Function To store items in a plastic case, open the lid to the case body, and insert the stored items into the storage recess formed on at least one side of the case body or lid while pulling up the elastic string member. When the stored item is stored and the lid is closed, both sides of the stored item are supported by the protrusions, and the stored item is held in an immovable state within the storage recess by the tensioned elastic string member that spans the top surface. be done. Therefore, even if the case is transported or falls over, the stored items will not swing unnecessarily and will be reliably protected. Moreover, even if the case is left upright when opened or the lid is turned downward, the stored articles will not fall out of the storage recess. The elastic string member that presses the top surface of the stored items is locked by inserting the locking members at both ends into the locking holes, so it can be easily attached and detached, and the storage recess is expanded in the opening direction. Therefore, it is easy to store or take out items, and it is extremely convenient.

Example An embodiment of the present invention will be described with reference to the drawings.

In Figures 1 to 3, 1 is a case body, and 2 is a lid body, and the case body 1 and the lid body 2 are connected by a hinge 3 which is compressed and thinned and molded to be flexible. The lid body 2 can be opened and closed with respect to the case body 1. Both the case body 1 and the lid 2 have a hollow double wall structure by blow molding, but the lid 2 may have a single wall structure.

A plurality of storage recesses 4 are formed in the case body 1, and the storage recesses 4 are slightly larger than the stored articles A, expand in the opening direction, and are formed lower than the height of the stored articles A. has been done.
In the storage recess 4 of the case body 1, two protrusions 5 are formed on each side wall of the storage recess 4 to support the side surfaces of the stored articles A.
By increasing the amount of protrusion in the opening direction of the storage recess 4
Even if the opening is expanded in the opening direction, the stored article A is supported in contact with the opening. Further, a weld rib 4a is formed in the storage recess 4 by welding and integrating the inner and outer walls.

An elastic string member 6 is attached between the end faces of both side walls of a series of adjacent storage recesses 4, with both ends thereof being locked across each storage recess 4.
This elastic string member 6 is used to press down the upper surface of the article A to be stored in the storage recess 4. That is, rotatable, rod-shaped locking members 7 are attached to both ends of the elastic string member 6, and locking holes 9 that follow the grooves 8 are formed in the end surfaces of both side walls of the plurality of storage recesses 4. The locking member 7 of the elastic string member 6 is locked in the locking hole 9 (see FIGS. 4 and 5). A plate member 10 for holding down the elastic string member 6 is fixed to the end face of the partition wall of the plurality of storage recesses 4 with rivets 11 or the like, and the elastic string member 6 is fixed thereto. 12 is a concave portion in which the elastic string member 6 is housed, and 13 is a concave portion in which the plate member 10 is housed. 14 is a latch, and 15 is a latch receiver.

In the plastic case constructed as described above, the stored articles A stored in each of the storage recesses 4 of the case body 1 are supported by the protrusions 5 on their side surfaces, and are supported by the elastic string members 6 on the top surface. Since the stored article A is held down by the handles, the stored article A remains immobile and is reliably protected. Even if the case is left standing or opened with the lid 2 facing downward, the stored articles A will not fall out unnecessarily.

In addition, since the elastic string member 6 is held down by the plate member 10 for each storage recess 4, each storage recess 4
It is possible to securely hold down the stored article A at each time. Also,
As shown in FIG. 2, the articles to be stored can also be stacked and held in two tiers. If the elastic string member 6 becomes an obstacle when storing or taking out the stored article A, it is convenient because it can be temporarily removed. In addition, the case body 1 that constitutes the storage recess 4
Alternatively, the lid body 2 may have a partially single-wall structure by cutting out a portion of the inner wall, for example, the inner wall that constitutes the bottom surface of the storage recess 4.

Effects of the invention According to the invention, the case body or lid has an integral structure with hollow double walls, is larger than the entire circumferential side of the stored items, expands in the opening direction, and is lower than the height of the stored items. Since the storage recess is formed, the elastic string member that is locked across the top surface of the stored items is always in a tensioned state, and can securely and firmly hold the stored items, and expand in the opening direction. A protrusion can be formed in the space to facilitate storage and removal of stored items. In addition, a locking hole penetrating the hollow part of the hollow double wall structure is provided on the opposite wall surface of the storage recess, and an elastic string member is provided at both ends with locking members that are rod-shaped and rotatable in the middle part. Since the tip of one of the locking members of the elastic string member is configured to be inserted into the hollow part of the case through the locking hole and rotated to be locked, the elastic string member can be easily and securely attached. The locking member is not exposed and does not interfere with article storage, and the shape around the storage recess is simplified, making it safe and convenient to use.
