Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a device for changing the height of a long container made of synthetic resin in the shape of an elongated box with an opening at the top. Regarding the technology to be used.

[Background Art] Conventionally, a box-shaped elongated container made of synthetic resin and open at the top has both end walls in the length direction, both walls in the width direction, and the bottom surface formed integrally in series, and the height is determined by handling. Due to the standardization of logistics, some items are difficult to store in an integrally formed container due to the standard, and for this reason, when handling tall items,
Containers of various heights are prepared, and therefore producers create molds of various heights to produce containers of various heights. The current situation is that this places a significant financial burden on people. By the way, with long containers, just because the height is changed, the strength of the end walls, side walls, and bottom plate does not have to be changed each time; it is only necessary to increase the height of goods storage. It is. By the way, in order to increase the height of a container, end wall materials for changing the height are erected on the end walls at both longitudinal ends of the container, and side walls are constructed between these end wall materials. Although it is conceivable to increase the height of the container, such a structure would weaken the strength of the corner portion connecting the end wall material and the side wall.

[Purpose of the invention] The present invention was devised in view of these problems, and its purpose is to make it easy for both the producer and the user to change the height. This eliminates the need to prepare a large number of molds with different heights, greatly reducing the economic burden on the user side, and further improving the strength of the corner of the container at that point while increasing the height. To provide a tool for changing the height of a long container, which can maintain the container in a high state.

[Disclosure of the invention] The height changing tool for a long container of the present invention is a box-shaped container with an open top and a long container main body 1 assembled at a constant height on end walls 2 at both longitudinal ends. An end wall material 3 for height change that is installed upright, and a side wall 4 of the container body 1 extending in series from both ends of the end wall material 3 in the container width direction on the corner side of the container body 1, respectively. A height changer main body 7 having a substantially U-shape in plan view is formed by the side wall holding members 6 , 6 erected on the side wall holding member 5 for assembling and holding the side wall holding members 6 .
The mounting portion 8 for mounting the side wall 4 with increased height is formed on the container main body 1 to constitute the mounting means 9 for mounting the height changer main body 7 to the container main body 1.
An insertion groove 10 is formed in the upper part of the side wall holder 5,
An insertion groove 1 is provided in the lower part of the end wall material 3 of the height changer main body 7.
A horizontal piece 36 that can be inserted and connected to the end wall material 3 is provided in a protruding manner, and an insertion groove 29 that can be inserted and connected to the end wall material 3 is formed in the upper part of the end wall material 3. By configuring it in this way, the above object has been achieved. That is, the height changer main body 7, which has a U-shape in plan view, is erected on the end wall 2 of the assembled container main body 1 and the side wall holders 5, 5 on both ends of the end wall 2, and the height changer main body 7 is erected. Means 9 for attaching the tool body 7 to the container body 1

Moreover, the height can be easily changed not only by the producer but also by the user, and the producer does not have to prepare a large number of molding molds with various heights. As a result, the economic burden on the consumer can be reduced. Moreover, since the height changer main body 7 is formed in a U-shape in plan view, it is possible to maintain the strength at the corner portion of the container with increased height, and the attachment means can be attached to the side wall of the container main body. An insertion groove is formed at the top of the tip of the holder, and a horizontal piece that can be inserted into and connected to the insertion groove is protruded from the bottom of the tip of the end wall material of the height changer main body. By forming an insertion groove into which the horizontal piece can be inserted and connected, the horizontal piece of the height changer body can be inserted into the insertion groove of the container body to attach the height changer body to the container body. If you want to increase the height further, you can insert and connect the horizontal piece of the height changer main body into the insertion groove of the lower height changer main body. The height can be increased one after another, and since the connections are made in the horizontal direction, the connections in the height direction cannot be accidentally disconnected without using any connectors.
