Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a paper case having a gusset for storing a CD (compact disk), a handkerchief, a scarf, a gift certificate, and other extremely thin items.

[0002]

[Prior art]

 A thin paper case for holding a handkerchief or the like is conventionally known. However, in the case of a thin paper case, the stiffness of the paper becomes relatively strong, so that the machine can only manufacture the blank until the blank is punched out, and the subsequent folding has to rely on manual labor. For this reason, the case was divided into a body and a lid, and the body was folded in itself to maintain a box structure, and the lid had a similar box structure. In order to assemble with a box making machine, the box must be completed by gluing, but an ultra-thin gusseted paper case with such a configuration is not yet known. Therefore, an ultra-thin gusseted paper case consisting entirely of one blank is also unknown.

[0003]

[Problems to be solved by the invention]

 The present invention has been made in view of the above points, and an object thereof is to provide an extremely thin gusseted paper case which is entirely formed of one blank and assembled by a box making machine.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides an ultra-thin gusseted paper case which is entirely formed of one blank and assembled by a box making machine, comprising: a front plate having a predetermined shape and size; The back plate, which overlaps with the front plate, and the lid, which serves as the lid of the case body, are connected in one direction by providing a gusset that gives the thickness to the case body between each plate. The front and rear panels are provided with similar gussets, and the left and right panels are bent, and the front and rear panels are bent. The lid has substantially the same shape and the same size as the front plate so as to hold down when the and the rear plate are joined, and the structure is formed at least double.

[0005]

[Embodiment of the invention]

 The present invention is an ultra-thin gusseted paper case made entirely of one blank. In the case of the present invention, in which the case is composed of the body (case body) and the lid, the whole means both the case body and the lid. Assembly becomes possible. The box-making machine includes the usual gluing means and performs the gluing process.

[0006] A blank is a blank that has only been punched out of a paper case material. However, the fold is made with a fold line to facilitate bending, and the separation part is in a separated state. In addition, the glue may be attached to the glue.

[0007] One blank is composed of a front plate, a back plate, a lid, and a connecting piece, and a gusset portion (also referred to as a lug portion) that gives the case body an extremely thin thickness between the plates. ) Intervenes. The front plate, back plate, and lid plate are continuous in one direction, and the joining pieces are located on the left and right of the front plate or back plate. Therefore, when the front plate is symmetric, one blank is left to one direction. It becomes right symmetric. The connecting piece is used as a margin.

[0008] There is no particular definition for the case of being extremely thin. However, since the device of the present invention is assembled by a box making machine, it can be said that a device having a gusset part thin enough to be not assembled by a conventional box making machine corresponds to an extremely thin type.

Although it has already been described that the paper case of the present invention has not only the case body but also the lid integrally, the lid has the same shape and the same size as the front plate, and has at least two layers. It is desirable to have this structure. By providing a double or more structure, the lid becomes twice as heavy and has at least the combined weight of the front plate and the back plate. This is because it is a holding down in a state in which are combined.

[0010] The paper case of the present invention further includes a cover part in a state where the case is assembled by bending the front plate, the back plate, the left and right connecting pieces, and at least the double cover. A detachable engaging projection and an engaging concave portion for fixing to the case main body can be provided on the cover plate portion and the case main body. The engaging protrusion and the engaging concave portion may be, for example, a tongue-like shape and a cut-out shape into which the tongue-like shape can be inserted, and these can also be formed at the same time when the blank is punched.

【Example】

 Hereinafter, the ultra-thin gusseted paper case 10 according to the present invention will be described in more detail with reference to the drawings. FIG. 1 shows a first embodiment, in which double lids 15 each composed of a substantially square front plate 11, a rear plate 12, and two parts 13, 14 are arranged in a line in the same order. Are provided with gusset parts 16 and 17. On both left and right sides of the front plate 11, connecting pieces 18 and 19 are provided via gussets 21 and 22, respectively.

A fold line 20 for facilitating folding is formed on the side of the boundary between the front plate 11 and the back plate 12 and the left and right connecting pieces 18 and 19. Although the fold line 20 is represented by a dashed line in FIG. 1, this is not intended to represent a perforation.

The left and right sides of the back plate 12 to which the bent connecting pieces 18 and 19 can come into contact are provided with portions 23 and 24 corresponding to the margins. The similar portion 25 is provided also at a place where the double lid 15 is bonded.

Therefore, when each part is bent along the folding line 20, the front plate 11 and the back plate 12 are closed on three sides, and the case body 27 having the opening 26 on the other side and the lid 15 are formed. A paper case 10 is formed. In FIG. 2, reference numeral 28 denotes an inner case, which accommodates a plate-like article 29 such as a CD.

The completed ultra-thin gusseted paper case 10 of the present invention has the same shape and size as, for example, a plastic CD case (see FIG. 3). The portion 30 can accommodate two or more CDs even in the same size as the plastic case (see FIG. 4).

FIG. 5 shows a second embodiment in which the left and right pieces of the lid 15 are closed by ear pieces 31 and 32, and the inside of the lid can be used as a gusset-free storage bag. From the opening 33 facing inward, for example, a thin pamphlet or the like can be stored. Reference numerals 34 and 35 denote portions where the ear pieces 31 and 32 extend. Since other configurations may be the same as those in the first embodiment, reference numerals are used and detailed description is omitted.

FIG. 7 shows a third embodiment in which the lid 15 can be fixed to the case body 27 by a detachable engagement protrusion 36 and an engagement recess 37. The engaging protrusion 36 is provided so as to cut and raise a part of the lid 15, and the engaging concave portion 37 has a structure in which a cut is made at a position of the case body 27 corresponding to the position of the engaging protrusion 36. In this example, an article 38 such as a gift certificate is to be stored, so that it has a horizontally long shape. Therefore, the description is omitted by using the reference numerals.

[Effect of the invention]

 Since the present invention is constructed and operates as described above, it is possible to provide an extremely thin gusseted paper case which is composed of the case body and the lid, and is entirely constituted by one blank. The whole is composed of one blank with the front plate, back plate, and lid body continuously arranged in one direction, so that it can be assembled automatically by a box making machine, making it extremely thin. However, as a gusseted paper case, there is an effect that articles can be stored neatly without being pressed or wrinkled.
