Description

[Detailed description of the invention] This invention relates to a roll storage box that allows rolled items such as aluminum foil and plastic film to be pulled out from inside the box in a stable manner. A plate, a bottom plate, a rear plate, a lid plate, and a bent plate are arranged in this order, and side plates and tongue pieces are arranged in this order on both ends of the bottom plate, and one side is set at the center of the side plate with a cutting line on three sides. A folding piece in which a substantially trapezoidal folding piece surrounded by a folding line is formed so as to be bendable, and further having a diagonal cut line corresponding to the slightly inner side of the oblique side of the folding piece at the tip at both ends of the front and rear plates. This invention relates to a roll storage box characterized by having pieces connected to each other.

To explain one embodiment of the present invention in detail with reference to the drawings, in Fig. 1, a front plate 1, a bottom plate 2, a rear plate 3, a cover plate 4, and a folding plate 5 are connected in order from the bottom to the top. A side plate 6 and a tongue piece 7 are successively provided at both ends of the bottom plate 2, and inside the side plate 6, three sides close to the bottom plate 2 are surrounded by a cutting line a, and a side far from the bottom plate 2 is surrounded by a cutting line a. A trapezoidal folding piece c that can be inserted into the hollow part of the roll object surrounded by the folding line b is formed, and the front and rear plates 1,
3, the folding piece 8 having a diagonal cut line d corresponding to the slightly inner side of the oblique side of the folding piece c is successively arranged at the tip thereof to constitute the whole. Thus, the portion of the folded piece 8 outside the diagonal cut line d is defined as the inner folded piece 81.

Regarding the assembly and use of the box according to the present invention, please refer to the second section.
As shown in the figures to FIG. 5, the front and rear plates 1, 3 and the side plates 6 are erected around the bottom plate 2, and the folded pieces 8 are folded on the inner surface of the side plates 6, and the side plates 6 other than the folded pieces c are
The diagonal cut line d of the folded piece 8 corresponds to the inside of the folded piece c of the side plate 6, and the one-piece blade 9 is attached to the inner surface of the upper edge of the front plate 1. In this state, the roll material 10 is attached. The entire body is constructed by storing the tongue piece 7, the lid plate 4, and the bending plate 5 in order, and rolls 10.
When the sheet is gradually pulled out and used, the above-mentioned folding piece c is pressed from the outside and the folding piece c and the inner folding piece 81 are inserted into the hollow portions at both ends of the roll object 10.
In this state, the roll 10 can be used stably.

In the above description, when the folding piece 8 is folded over the inner surface of the side plate 6, the diagonal cut line d runs close to the inside of the trapezoidal oblique side of the cut line a and is located near the upper end. Cut e that bends strongly in the diagonal horizontal direction
It is bored so as to be connected to the end of the fold line b. Therefore, when the folding piece c is pressed into the box, the folding piece 8 near the notch e pinches and locks the upper end of the folding piece c, and the folding piece c tries to fold back outward. deter. Also, the hole f formed after the folding piece c
The portion 82 of the folding piece 8 protruding inward also prevents the folding piece c from folding back outward. Furthermore, in the present invention, the fold line b is provided approximately at the center of the side plate 6, and the cut line a is provided such that its lower end is located below the inner wall of the hollow part on the bottom plate 2 side of the roll object 10 stored in the box. be. That is, the folded piece c is formed longer than the radius of the hollow part of the roll object 10. Therefore, when the folding piece c tries to fold back outward, the tip of the folding piece c collides with the inner wall of the hollow part of the roll object 10 and causes friction, which prevents the folding piece c from folding back outward. .

As mentioned above, in the box according to the present invention, a folding piece that can be pushed into the box as necessary is formed in the center of the side plate, and the folding piece that has been pushed in is prevented from folding back outward. This mechanism allows the folding pieces to be easily pushed into the hollow parts on both sides of the rolled object during use, stabilizes the rolled object, and allows the film sheet to be pulled out smoothly. It has the feature of being able to prevent it from jumping out in the opposite direction.
