Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a box that can store the contents in a light-shielded state and also allows easy removal of the contents.

[Technical background]

There have been many boxes in the past that can maintain a light-shielding condition, but even when storing contents in the form of single sheets, the structure is complicated and difficult to assemble mechanically.

Other structures include ones in which a light-shielding material is pasted on the inner surface of the box, but boxes with other materials on the inner surface like this are troublesome to put in and take out the contents, and even more difficult to store the contents in a dark place. The task of loading and unloading became even more difficult.

[Purpose of invention]

The object of the present invention is to provide an assembled box made of one material, which allows easy removal of the rolled contents, and furthermore, a box that is easy to handle in a dark place.

[Means for solving problems]

A square box with an open storage compartment at the top.
A folding piece is provided at the upper part of the four side walls of the storage part via a fold line, a top plate having the same size as the bottom is provided at a position opposite to the folding piece, and a folding part is provided between the turning piece and the top plate. This folding part has a triangular folding piece connected to the side wall, a folding corner piece connected to the return piece on one side of the folding piece, and a top corner piece connected to the top plate on the other side. .

Then, at the same time as the return piece is folded in, the folded corner piece of the folded part is folded from the fold line to the inside of the folded piece, and the top corner piece is folded to the outside of the top plate, and then folded so as to overlap the folded piece, sealing the top of the storage part. This box has a light blocking effect.

[Effect]

The upper part of the storage part can be sealed in a light-shielding state by overlapping the top plate, the folding piece, and the folding part, and there is no need to use a separate member.

〔Example〕

For example, as shown in FIG. 1, a rectangular top plate 21 with the same width, a rear wall 13 having a fold line 31 in the middle, a bottom 11, a front wall 12, a return piece 22, and a reinforcing piece 33 are connected through a fold line. Trapezoidal top corner pieces 25, 25, triangular rear folded pieces 24, 24, and trapezoidal rear horizontal side wall 1 are attached to the left and right sides of the member via fold lines, respectively.
5, 15, triangular gluing margins 41, 41, square joining pieces 32, 32, trapezoidal front side walls 14, 14 and triangular triangular gluing margins 41, 41, and triangular folding corner pieces 26, 26 and folding The front pieces 23, 23 are provided, and the members provided on the left and right of these are the top plate 21,
Rear wall 13, bottom 11, front wall 12 and return piece 2
They are sequentially connected via a fold line that is an extension of the fold line between the two.

Here, the triangular folded back piece 24 is the top corner piece 25.
The top corner piece 25 is located between the rear side wall 15 and the rear side wall 15.
It touches the upper outer edge via a fold line extending at 45°,
The triangular glue margins 41 are arranged in line-symmetrical positions with the joining piece 32 in between, and the folding corner piece 26 is located between the triangular front folding piece 23 and the turning piece 22. Further, elongated glue margins 42 are provided on the outer sides of the front horizontal side wall 14 and the front folding piece 23, respectively.

Then, adhesive is applied to the back surface of the triangular glue margin 41 and the surface of the glue margin 42 shown in FIG. 42 and then valley-folding along the fold line 31, the folded state shown in FIG. 5 can be obtained.

When storing the contents, the folded box shown in FIG. 5 is erected from both sides and the top plate is pulled up to form an opening at the top as shown in FIG. 2. In this state, the contents rolled into a roll are stored, and then, as shown in FIG. By folding the folded piece 24 outward, it is stacked on the return piece 22 and sealed as shown in FIG. 4.

〔effect〕

As explained above, the box of this invention can be made by simply folding the top plate and the return piece, stacking them together and sealing them.
It has a light-shielding effect and does not require any separate members, so it can not only be mechanically assembled easily, but also the contents can be sequentially pulled out from between the top plate and the return piece.

In addition, before storing the contents, it can be folded flat as shown in Figure 5, and when stored, by pushing the folded item from both sides, an opening is created at the top and it can be stored in a dark place. It can also be easily stored.

[Brief explanation of the drawing]

The drawings show an example of the present invention; FIG. 1 is a developed view, FIGS. 2, 3, and 4 are explanatory diagrams showing the assembled state of FIG. 1, and FIG. 5 is an illustration of the contents. It is a folded state figure before storing an object. 11: Bottom, 12: Front wall, 13: Back wall, 1
