Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a conventional prefabricated one-piece box comprising a box body and a lid connected with each other and made of a sheet of paper cannot be closed in such a way as to cover all side walls of the box body made of the body with the lid and this is a fatal disadvantage of the one-piece box. <P>SOLUTION: This one-piece box is constituted by connecting the body box having the side walls on all the peripheral sides of a box body bottom face, and a lid box having side walls on all the peripheral sides of a lid box top face with a hinge part having a length smaller than the height of the side wall of the body box at each apex part of the side wall of one side, and sticking a part or the whole face of the hinge part with the outer side face of the side wall of the body box from the connecting part. It is possible thereby to cover the lid on all the side walls of the body box. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

The present invention relates to a novel hinge structure technique for an assembly-type one-piece box in which a body made of a piece of paper and a lid are integrated.

The body box and the lid box, which have been used for Japanese confectionery boxes and shoe boxes, are completely independent, and there is a normal paper box on the body box that covers the entire side wall of the body box. On the other hand, there is what is called a one-piece box with a structure in which one side of the body box and the lid box is connected. In particular, a one-piece box made of a piece of paper with its body and lid is easy to manage and easy to use in the production process and at the stage of use because the body and lid do not fall apart. One-piece boxing has been attempted even in a pasting box format (for example, see Patent Document 1 and Non-Patent Document 1) and a seal stamp format (for example, refer to Patent Document 2), which are not suitable for making a sandwich box. For example, a one-piece box is widely used in an inexpensive take-out assembly box type (see, for example, Patent Document 3).

In the one-piece box of the sticker box type, both side walls of the center part of the box are cut out and bent at the center part to make the body and lid, so there is no back side wall of the body box as a basic box when the lid is opened The structure lacks the function of. In addition, the stamp box type one-piece box is surely a one-piece box and lid box, but an inner box is required inside the box. In the assembly box format, the lid has a low specification as a lid function at the level of attaching a side wall to both sides of the lid, or a piece of paper having a tongue inserted into the body box at the tip.
JP2000-142669 (page 7, Fig. 7) Japanese Patent Laid-Open No. 11-301657 (page 4, FIG. 1) Utility Model Registration 3074292 (Page 2, Fig. 1) "Stokes News", Kubo Seisakusho October 1995 No. 1, One Piece Box

In the case of a one-piece box with a pasting box method as shown in Patent Document 1 and Non-Patent Document 1, when the lid is opened, the body box is not completely surrounded by the side wall, and as a container for small contents In addition to being unsuitable, it also lacks hermeticity as a confectionery container and is unsanitary. In addition, the side wall ends (hinge side) on both sides of the lid are not fixed, and the appearance is poor, which impairs the sense of quality.

  In the seal type one-piece box as shown in Patent Document 2, the body box and the lid box are one-piece boxes connected by a single sheet of paper, but a separate inner box is required and is different from the original one-piece box. .

  Moreover, in the assembly box as shown in Patent Document 3, the body box has a side wall on each side, but the lid has only one top surface or a simple lid such as inserting the tip of the lid into the body box. Did not exist. In addition, even if the lid is attached to the lid by any method, the lid can only be connected to the uppermost end of the body box side wall, so the side wall of the entire top surface of the lid cannot be obtained, and the side walls on both sides of the lid are not fixed. The situation is not different from the problem with the above-mentioned one-piece box.

  The present invention is intended to solve the problem of such a conventional configuration, and covers all the side wall surfaces of the body box against the body box while being a one-piece box made of one sheet of paper. The present invention is to provide an unassembled one-piece box that can be covered with a side wall.

  In order to achieve the above-mentioned object, the present invention consists of a sheet of paper having a side wall around the entire bottom of the chest and a lid box having a side wall around the top of the lid. Connect the tip of one side wall with a hinge that has a length that does not exceed the height of the side wall of the body box (see FIGS. 1 and 2), and cover the whole side wall of the body box when the lid is closed. (See FIGS. 3, 4, 5, and 6).

  Further, the second problem solving means is to bond a part or all of the hinge part to a part or all of the hinge part on the outer side surface of the side wall of the body box to which the hinge part is connected. The structure is fixed to the side wall (see FIGS. 4, 6, and 8).

  The operation of the first problem solving means is as follows. In a one-piece box made of a sheet of paper according to the prior art, a lid or lid box that covers all the side walls of the body box cannot be made because a part of the lid or the lid box is directly connected to the tip of the side wall of the body box. According to the present invention, by providing a hinge portion between the body box and the lid box, the hinge position of the lid with respect to the body box can be removed from the tip portion of the side wall of the body box. A one-piece box that can be covered with a lid box having a side wall that surrounds all sides of the top surface of the lid box can be formed on a body box having a surrounding side wall.

  Further, the second problem solving means can fix the hinge position of the lid by adhering a part or the whole of the hinge part to the outer side wall of the body box to which the hinge part is connected. The effect of facilitating closing is exhibited (see FIG. 8). If the hinge part and the side wall of the body box are not bonded and fixed, the hinge position is not fixed when the lid is closed, and the lid cannot be closed properly (see FIG. 7).

  As an unexpected effect, it turned out that it was easy to put the product in the body box and stop the lid box in a half-closed state from one-third, and the display effect at the time of sale could be simplified.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. In the figure, 1 is the bottom of the body box, and 4, 5, 6, and 7 are side walls of the body box. Similarly, 3 is a top surface of the lid box, and 8, 9, 10, and 11 are side walls of the lid box. A hinge portion 2 is connected to the body box side wall 5 and the lid box side wall 11. The length connecting the hinge box and the lid box should not exceed the height of the side wall 5.

  Side walls other than the body box side wall 5 and the lid box side wall 11 are doubled in order to be folded back into side walls. The corner folds are connected to the side wall directly connected from the bottom of the body box and the top of the lid box, 19a and 18a at both ends of 4b, 20a and 21a at both ends of 6b, and 22a at both ends of 8b. 24a and 25a are bonded to both ends of 10b, and the bonded corners are covered by folding 4a and 6a in the body box and 8a and 10a in the lid box inside the box. 7a and 9a are folded inside the body box and the lid box so that the tip folds 13 and 16 of 7a and 9a hold down the tip folds 12, 14, 15, and 17 of 4a, 6a, 8a, and 10a from above. It has become.

  The hinge part 2 and the side wall 5 of the body box are partly or entirely bonded from the connecting part to the lower side of the side wall to save the movement of the hinge part.

  The size of the lid box is such that the length of the side walls 9 and 11 is longer than that of the body side walls 5 and 7 by at least the paper thickness. Further, the lengths of the lid box side walls 8 and 10 need to be longer by the paper thickness than the diagonal lengths of the body box side walls 4 and 6 assuming that the lid is closed from the state shown in FIG.

  The paper used in the present invention is not limited, but a type called high-quality paper or high-quality coated paper which is usually commercially available is desirable. Further, the present invention is not limited to any method of making a body box and a lid box, and it is obvious that the present invention can be adopted by an assembly box system other than the embodiment.
