Description

[Detailed description of the invention] <Industrial application field> This invention makes it possible to pull out rolled objects such as aluminum foil and plastic film from the box in a stable state. This relates to a roll storage box.

<Prior art> Conventionally, as shown in Japanese Utility Model Publication No. 61-34265 and Japanese Utility Model Publication No. 61-43702, which were already developed by the applicant of the present invention, roll objects have been constructed so as to be pulled out from inside the box in a stable state. The technology of roll storage boxes is known.

<Problem to be solved by the invention> However, in the above-mentioned known technology, a cutout or folded piece is provided in a part of the end plate of the box, and these are inserted into the paper that becomes the core material of the roll stored in the box. The mechanism was pushed into the hollow part of the tube to stabilize the roll in the box, but it was difficult for consumers who purchased the roll to recognize the mechanism itself, or they did not recognize it. However, the pushing operation method is troublesome and time-consuming, so it is rarely used in practice and is of no use.

Recently, as shown in Japanese Utility Model Application Publication No. 59-22725, U-shaped spaces are bored in both corners of the outer tip of the folding tongue provided on the upper edge of the box.
There is also a known technique in which the tips of the folding tongues are inserted into the inner periphery of both ends of a stored roll, and the film wound around the roll is passed through the U-shaped space of the folding tongue. However, in the case of this technique, the folding tongue piece folded into the inside of the box is pressed by both ends of the rolled material stored in the box, and the whole folding tongue piece comes into close contact with the inside of the box. There were problems such as the glyph space part not functioning at all.

The box according to the present invention relates to a completely new technology developed in view of these drawbacks of the conventional technology.

<Means for Solving the Problems> The present invention is a technology that fundamentally improves the conventional problems mentioned above, and its gist is that the bottom plate, front and rear side plates, end plates, cover plate, insert plate, etc. In the roll storage box, folding tongues that can be folded into the box are connected to the upper ends of both end plates, and a cutting line is formed from approximately the center of the folding tongues to one outer corner edge. A ridge-shaped protrusion piece is formed on the outside of the corner part by being separated from the folding tongue piece body,
When the folding tongue piece is folded along the inner wall surface of both end plates, the mountain-like protrusion piece is separated from the main body of the folding tongue piece and projects diagonally downward from the upper part of the inside of the box.

<Function> As mentioned above, the roll storage box according to the present invention has a bottom plate. In a roll storage box consisting of front and rear side plates, both end plates, a lid plate, an insert plate, etc., a folding tongue piece that can be folded into the box is connected to the upper end of both said side plates, and approximately Since a cutting line was drilled from the center to the outer corner edge to form a mountain-like projection piece at the corner part, when the folding tongue piece was folded into the inner wall surface of both end plates of the storage box, this Since the mountain-like protrusion piece is separated from the main body of the folding tongue piece and protrudes diagonally downward from the top of the box, the outer peripheral surface of the rolls stored in the box must always be pressed by this mountain-like protrusion piece. I can do it. Therefore, it is possible to stabilize the rolled object within the box and prevent the rolled object from jumping out of the box.

The main body of the folding tongue is separated from the mountain-shaped protruding piece of the folding tongue by a cutting line cut from the center to the corner edge, so when the folding tongue is folded into the box, The mountain-like protrusion piece can be automatically made to protrude obliquely within the box. In addition, even if the main body of the folding tongue piece is pressed by a rolled object stored in the box, the ridge-like protrusions are not affected by this and press the outer circumferential surface of the roll object with the ridge-like protrusions. I can do it.

<Example> An embodiment of the box according to the present invention will be specifically explained with reference to figures. In Figs. 1 to 4, A is a blank plate of the box according to the present invention, and the folding line is The front side plate 1, the bottom plate 2, the rear side plate 3, the cover plate 4, and the insertion plate 5 are connected in order through The folding tongue pieces 8 are connected in sequence, and insertion grooves 9 into which the corner parts of the insertion plate 5 can be inserted are formed on both sides of the front and rear plates 1. Furthermore, a predetermined distance a from the approximate center of the folding tongue piece 8, that is, the side adjacent to the end plate 7.
An arcuate cutting line 10 in the shape of a box or an inverted box is bored from the center of the grip toward the corner on the front side plate 1 side, and a mountain-like protrusion piece 8 is formed on the outside of the tip corner.
a is constructed separately from the main body portion of the folding tongue piece 8.

In constructing the box according to the present invention, a saw-blade cutter 11 is attached to the upper edge of the front plate 1, as in conventional boxes of this type, and the entire blank plate A is arranged around the bottom plate 2. It is constructed by folding it. With this structure, the box can store rolled objects 12 such as aluminum foil sheets.

Next, when using the box of the present invention, as shown in FIG. After being folded along, the roll 12 can be stored. When storing the roll object 12 in this way, since the folding tongue piece 8 is provided with the mountain-like protrusion piece 8a separated from the main body part through the arcuate cutting line 10, the mountain-like protrusion piece As shown in FIG. 4, the protrusion 8a is obliquely protruded from the top to the bottom inside the box, and the outer circumferential surface of the roll 12 can be pressed by the protruding mountain-like protrusion piece 8a. Thereby, as shown in FIG. 5, when the tip of the roll object 12 is pulled out, it is possible to prevent the stored object from flying out.

In the above embodiment, the folding tongue piece 8 is provided with an arcuate cut line 10, but this cut line 10 is a straight cut line 10a as shown in FIGS. It may also be a oriented arcuate tangential line 10.

<Effects of the invention> As mentioned above, the box according to the invention has a folding tongue piece that can be folded into the box connected to the upper edge of both end plates,
In addition, since the outer cutting line of the corner part is formed at a predetermined position of this folding tongue piece to form a mountain-like protrusion piece, the outer peripheral surface of the rolled object is held down by this mountain-like protrusion piece, and the rolled object is folded into a box. It can prevent them from jumping out.

In addition, as mentioned above, when storing roll items in a box, the mountain-like protrusion piece can automatically operate separately from the main body of the folding tongue piece, so that it is possible for consumers to It is characterized by the fact that there is no need to operate a mechanism to prevent the device from popping out, and it is safe and reliable to handle.
