[Industrial applications]

 The present invention relates to a paper box.

[0002]

[Prior art and its problems]

 Conventionally, in a paper box that stores small items such as confectionery products, various measures have been taken to improve the appearance and enhance the design. However, if the design is improved, the structure of the paper box itself becomes extremely complicated, and it becomes impossible to manufacture the paper box using the assembly machine.Therefore, there is a disadvantage that the manufacturing cost is significantly increased. Attempts to improve the design of paper boxes made them unsuitable for mass production.

In view of the above-mentioned circumstances, the present invention has an object to improve the design of the paper box so that the sack can be attached to match the machine, and the paper box having the excellent design can be mass-produced. The purpose is to enable low-cost manufacturing.

[0004]

[Means for Solving the Problems]

 The present invention has been made in consideration of the above-mentioned problems, and an outer top plate, a side plate, a bottom plate, a side plate, and an inner top plate are sequentially connected to each other through folding lines, and the inner top plate is connected to the inner top plate. An outer top plate that covers almost the entire surface of the box is bonded to form a box body, and a lid plate that opens and closes both side openings of the box body is formed on the opposite sides of the inner top plate. The top plate and the inner top plate are connected to each other via folding creases that are curved so as to be convex toward the center of the top plate, and when the lid plate is folded into the body opening across the curved crease lines. To solve the above-mentioned problems, a paper box is provided, which has a shape-retaining auxiliary process for facilitating the lifting of the laminated top surface.

[0005]

[Action]

 In the present invention, the lid plate is continuously provided on each side of the inner top plate forming the top surface of the box body via the folding ruled line that is bent so as to be convex toward the center of the inner top plate. However, by bending this lid plate from the above-mentioned folding ruled line, the top surface of the box body is lifted, and the box shape becomes extremely novel. Further, the outer top plate, the side plate, the bottom plate, the side plate, and the inner top plate are sequentially connected via folding ruled lines, and the outer top plate is attached to the inner top plate to form the box body portion. The structure is similar to that of the pasted box, and this box can be assembled by a machine and automatically assembled.

【Example】

 Next, the present invention will be described in detail based on the embodiment shown in FIGS. In the drawing, 1 is a paper box, and as shown in the blank state of FIG. 1, the paper box 1 has an outer top plate 2, a side plate 3, a bottom plate 4, a side plate 5, and an inner top plate 6 in order via a fold line a. The side plates 3 and 5 are arranged in series, and the flaps 7 are connected to the respective sides (upper and lower sides in the drawing) opposite to the direction in which the side plates 3 and 5 are connected, respectively, via folding creases b, and The lid plate 8 is provided on each of the opposite sides (upper and lower sides in the drawing) in a direction different from the above-described continuous installation direction of the plate 6 via a fold line c curved so as to be convex toward the center side of the inner top plate. The cover plate 8 is continuously provided with an insert piece 9 via a fold line d. Then, the box body 10 is formed by adhering the outer top plate 2 that covers almost the entire surface of the inner top plate 6 to the inner top plate 6, that is, by attaching the sack, and the flap 7 is folded. After folding down, the paper box 1 is obtained by covering both openings of the box body 10 with the cover plates 8.

On the inner top plate 6, shape retention assisting 11 is applied between the folding ruled lines c. This shape-preserving auxiliary processing 11 is one in which half cuts by multiple lead blades, perforations and folding lines are put in parallel on the inner top plate 6, and the top surface A of the paper box 1 faces upward as described later. It is designed to be easily lifted. The side of the inner top plate 6 facing the side plate 5 is located slightly on the side plate 5 side, as shown in FIG. 1, and the connecting portion 12 of the outer top plate 2 and the side plate 3 is positioned. An engaging portion 13 is provided. That is, the edge of the inner top plate 6 is recessed from the edge of one lid plate 8 through the edge of the inner top plate 6 to the edge of the other lid plate 8, and this step is The continuous portion 12 is fitted into the engaging portion 13 formed by the above so that the outer top plate 2 is properly attached to the inner top plate 6. FIG. 2 shows a state before the outer top plate 2 is attached, and the outer top plate 2 is slightly open.

When the lid plate 8 is folded down from the curved crease line c, the top surface A formed by bonding the outer top plate 2 and the inner top plate 6 is curved and lifted, and the lid plate 8 Also, the folding line c is dented, and the paper box 1 obtained by inserting the insertion piece 9 of the lid plate 8 has a novel shape in which the top surface A is lifted in an arc shape and the top surface side of the lid plate 8 is dented as shown in FIG. It becomes a shape. Here, the shape retention auxiliary processing 11 provided on the inner top plate 6 fulfills the following characteristics. That is, in the paper box of the present invention, by bending the cover plate 8, a force is exerted to the inner and outer top plates via the fold line c. However, this force works well at the edges of the inner and outer top plates, but becomes weaker toward the inside. As a result, the edges of the inner and outer top plates are lifted upward, and the inner portion (center portion) is not lifted sufficiently upward, which may result in a recessed state, which is not desirable in appearance. Shape-relieving auxiliary machining functions to eliminate this phenomenon. In other words, by performing this shape-preserving auxiliary processing, it is possible to improve the bending resistance of the inner top plate in the direction parallel to the shape-preserving auxiliary processing (long side direction in Fig. 2). The upward force applied to the edge is sufficiently transmitted to the inside of the inner top plate and lifts upward. In the shape retention assisting process, the inner top plate is easily curved in the direction orthogonal to the shape retention assisting process (short side direction in Fig. 2). Due to the two functions added by the shape-preserving auxiliary processing, the inner and outer top plates can be easily and beautifully lifted upward during assembly. In addition, since the shape-preserving processing is provided only on the inner top plate, this part is covered by the outer top plate after the box is assembled, so there is no adverse effect on the appearance of the box. In the paper box of this embodiment, it is possible to change the width and the like of each plate member, and various paper boxes with different balances can be obtained. The outer top plate need only have a size and shape that cover almost the entire surface of the inner top plate, and does not necessarily have the same size and shape. In other words, the minimum requirement is that the shape and shape of the inner top plate should be covered during assembly, and any other shape can be freely set in consideration of the external appearance of the design. In addition, the inner and outer top plates may be attached entirely or partially.

4 to 6 show a second embodiment. The second embodiment is different in that the folding ruled line c in the above embodiment is a mountain-shaped folding ruled line e, and a half cutting is performed by one lead blade between the tops f of the folding ruled line e. The difference is that shape-preserving auxiliary processing 11 consisting of perforations and folding lines is applied. FIG. 5 shows a state before the outer top plate is attached, and the outer top plate is drawn as if it is slightly open. Also in this second embodiment, the top plate A is lifted up like a roof with the part provided with the shape-retaining auxiliary processing 11 as the tip by folding the cover plate 8 down, and the cover plate 8 also has the folding line f side. It becomes a dented state and becomes a paper box 1 with a novel shape. Also in this embodiment, it is possible to change the width and the like of each plate material, and various paper boxes with different balances can be obtained.

[Effect of device]

 As described above, in the paper box of the present invention, the outer top plate, the side plate, the bottom plate, the side plate, and the inner top plate are sequentially connected through the folding ruled lines, and the inner top plate is almost entirely over the inner top plate. A box body is formed by adhering outer top plates that cover the inner top plate, and cover plates that open and close both side openings of the box body are provided on opposite sides of the inner top plate and on the center side of the inner top plate. Consecutive creases that are bent so as to be convex are provided continuously, and the outer top plate and the inner top plate are attached to each other when the lid plate is folded into the body opening across the bent crease lines. It is characterized by shape-retaining auxiliary processing that makes it easier to lift the surface. In this way, the box body is obtained by bonding the inner top plate and the outer top plate with the side plate and the bottom plate interposed, so that it can be reassembled in the same manner as a normal sack-attached paper box. It became possible to bond them using a machine, and it was possible to mechanize this paper box to be assembled by a machine, and the size and shape could be freely set at a low cost, and it had an outer top plate, and the top surface, It offers a highly practical effect, such as being able to provide a paper box with a novel shape in which the lid plate is deformed.
