Description

  The present invention relates to a packaging paper box.

  Conventionally, there is a hexahedron-shaped packaging paper box containing a tube container or the like. Patent Document 1 proposes a folding tissue carton that can be folded into a flat shape convenient for disposal. In the above carton, the bottom piece or the top piece is divided to provide a cutting machine line for connecting the ends of the end face piece connecting edges to form the pushing piece a, and the pushing piece a is pushed open, The ruled edges can be separated and easily pushed down to form a flat shape (the scope of claim for registration of utility model, line 4 to line 2 from the bottom of page 3, line 5 to line 4 to line 10).

In the carton described in Patent Document 1, the end face piece is stuck on the end face flap, and the pushing piece a and these are separated together (see FIG. 3 (b)). In addition, when the end face piece is stuck on the end face flap and the end face portion is relatively strong and force is applied from above and below, the end of the carton is not easily deformed, and the push piece a is pushed open. The opening stability is also good.
On the other hand, as a wrapping paper box, end face pieces are not stuck on end face flaps (inner flaps), the inner flaps facing each other are folded, and the end face pieces (outer flaps) facing the outside are folded and overlapped and sealed. Some are molded. When the pushing piece formed by the above-mentioned cutting machine wire is provided at the end of this paper box, when pushing the pushing piece open, the pushing piece and the outer flap connected to the pushing piece are in a state of being sandwiched between them. There was a drawback that unsealed inner flaps were pinched together and picked, resulting in poor openability (for details, see the description in paragraph 0013).

On the other hand, if the inner flap is made smaller or eliminated so as not to pinch the inner flap, the strength of the edge of the paper box will decrease, and the edge of the paper box will be deformed when force is applied from above and below. There was a drawback that the stability was poor when the pushing piece was pushed open. In particular, if the upper edge of the inner flap is inclined downward from the root portion connected to the edge with the side plate toward the tip, it is difficult to bend the inner flap at right angles using the edge as a crease. The forming state is broken, the crease is rounded, and both ends of the cutting machine wire are easily broken. In addition, there is a defect that a gap is formed between the inner flap and the outer flap in the vicinity of the fold so that dust or the like can easily enter.

  The problem to be solved is that the inner flap is folded and overlapped, the outer flap facing the outside is folded and overlapped and sealed, and formed at the end of the wrapping paper box with a cutting machine line When the pressed piece is provided, the strength is lowered, and the unsealing property and the molded state are changed.

  The present invention comprises a top plate, a bottom plate, a pair of left and right side plates, an outer flap connected to the front and rear edges of the top plate and the bottom plate, and an inner flap connected to the front and rear edges of each side plate. A wrapping paper box formed by folding a flap and folding an outer flap opposite to the outer flap and sealing it. The top plate has an arcuate shape with the edge between this and the outer flap as a string. A substantially arc-shaped break line is provided, and an upper edge of each inner flap is provided with a linear base in a substantially horizontal direction and an inclined portion inclined downward toward the tip. The most important feature is the packaging paper box.

  The wrapping paper box of the present invention is formed by folding and overlapping the inner flap, folding the outer flap facing the outside and overlapping and sealing it, and forming a pushing piece formed with a cutting machine wire at the end. In this case, there is an advantage that the strength is hardly lowered and a good opening property and a molded state can be obtained.

  Hereinafter, the present invention will be described based on examples, but it goes without saying that various application modifications can be made without departing from the spirit of the present invention.

  FIG. 1 is a development view of the packaging paper box of the present invention. FIG. 2 is a schematic perspective view of the packaging paper box of the present invention. FIG. 3 is a schematic perspective view showing an opened state of the packaging paper box of the present invention. FIG. 4 is a schematic perspective view showing a folded state of the packaging paper box of the present invention.

  The wrapping paper box 1 of the present invention includes a top plate 2, a bottom plate 3, a pair of left and right side plates 4, 5, outer flaps 6 and 7 connected to front and rear edges of the top plate 2, and front and rear edges of the bottom plate 3. The outer flaps 8 and 9 to be connected, the inner flaps 10 and 11 connected to the front and rear edges of the side plate 4, the inner flaps 12 and 13 connected to the front and rear edges of the side plate 5, and the seal piece 14 connected to the edge of the bottom plate 3. It consists of. As the material of the wrapping paper box 1, various materials such as paperboard can be selected. The opposing direction of the top plate 2 and the bottom plate 3 is the vertical direction, the opposing direction of the side plates 4 and 5 is the left-right direction, and the opposing direction of the outer flaps 6 and 7 is the front-rear direction.

  On the upper edge (top plate 2 side) of the inner flaps 10, 11, 12, and 13, a linear base 20 is provided in the substantially horizontal direction, and an inclined portion 21 that is inclined downward toward the tip is provided. Each inner flap is substantially the same height as the side plates 4 and 5 at the base 20. When the top plate 2 and the bottom plate 3 have a lateral width of about 40 to 50 mm and the side plates 4 and 5 have a height of about 19 to 23 mm, the length of the base 20 is preferably about 7 to 8 mm. In accordance with the size, each part can be configured with the size of the above ratio. The lower edges of the inner flaps 10, 11, 12, 13 are each linear in a substantially horizontal direction. The inner flaps 10 and 12 are preferably sized so that they do not overlap when folded, but may be sized so that they are partially overlapped. The same applies to the inner flaps 12 and 13.

  The top plate 2 is provided with rupture lines 18 and 19 each having an arcuate arc shape with the edges 16 and 17 between the front and rear outer flaps 6 and 7 as strings. Both ends of the breaking lines 18 and 19 are connected to the left and right corners of the top plate 2. The breaking lines 18 and 19 can be provided in a circular arc shape, a trapezoidal shape, a mountain shape, or the like by perforations (including those of dotted lines and alternate long and short dash lines), cuts, and the like. Pushing pieces 30 and 31 are formed by providing the breaking lines 18 and 19. The rupture lines 18 and 19 and the upper edges of the inner flaps 10, 11, 12, and 13 are each of a relative shape so as to avoid the inner flap from being picked by the pushing piece when opened as described below. It is good to form in size.

When forming the packaging paper box 1, the sealing piece 14 and the side plate 4 are sealed, and the top plate 2, the bottom plate 3, and the pair of left and right side plates 4, 5 are connected to each other. Further, the opposed inner flaps 10 and 12 are bent in a direction approaching each other, and the outer flaps 6 and 8 facing the outside thereof are folded in a direction approaching each other and overlapped and sealed to close the opening. The outer flaps 6 and 8 can be stacked with any top, but it is better to have the outer flaps 8 upward. Similarly, the inner flaps 11 and 13 and the outer flaps 7 and 9 are closed. In addition, the contents such as the tube container are accommodated in an arbitrary step during the above-described closing. The wrapping paper box 1 of the present invention has a hexahedral shape in which the folds on each surface are bent at right angles, and it is difficult to form gaps at the corners, and the molding state is good.
In addition, although the break line 18 and 19 was provided in the top plate 2, and the aspect which provides the base 20 and the inclination part 21 in the upper edge in each inner flap was demonstrated, if said relative positional relationship is achieved, The bottom plate 3 may be provided with break lines 18 and 19, and the base 20 and the inclined portion 21 may be provided on the lower edge of each inner flap. The top plate 2 and the bottom plate 3 may be provided with break lines 18 and 19, and the base 20 and the inclined portion 21 may be provided at the upper and lower end edges of each inner flap.

Next, the operation and effect of the packaging paper box 1 of the present invention will be described.
As shown in FIG. 3, first, the pushing piece 30 of the closed paper box is pushed with a finger to break the top plate 2 along the breaking line 18, and the edge 16 between the top plate 2 and the outer flap 6 is broken. The opening is opened so as to reach both ends. That is, the pushing piece 30 separated from the top plate 2 and the sealed outer flaps 6 and 8 are bent forward with the edge between the bottom plate 3 and the outer flap 8 as a crease, thereby opening the opening. The pushing piece 31 and the outer flaps 7 and 9 are also opened at the same time or independently, as in the above case. The end of the paper box 1 has strength, and the pushing pieces 30 and 31 can be pushed with a finger to break the top plate 2 along the breaking lines 18 and 19 so as to be surely opened.

  In this case, for example, when the pushing piece 30 is pushed with the thumb and the outer flaps 6 and 8 are supported by the index finger, the pushing piece 30 and the outer flaps 6 and 8 are picked by the thumb and the index finger when the breaking line 18 is broken. It becomes a state. At this time, if the upper end portion (top plate 2 side) of the inner flaps 10 and 12 is about the same height as the top plate 2, this portion is placed between the pushing piece 30 and the outer flaps 6 and 8. There is a drawback that it is pinched together and unsealed. Further, if the inner flaps 10 and 12 are gripped and are torn apart, there is a problem that they become garbage. In the present invention, the upper edge of the inner flaps 10 and 12 is provided with an inclined portion 21 that is inclined downward toward the tip, thereby avoiding the drawbacks of picking the inner flap, and opening and disassembling / disposing. There is an effect that the ease is improved. The above operations and effects are the same for the pushing piece 31, the inner flaps 11, 13, and the outer flaps 7, 9.

Furthermore, in the present invention, linear base portions 20 are provided in the substantially horizontal directions at the upper edges of the inner flaps 10, 11, 12, and 13, respectively. Thereby, when the top plate 2 is supported by the base portion 20 of each inner flap at the time of closing and a force is applied from above and below, the strength of the end portion of the wrapping paper box 1 is ensured and is not easily deformed. Play. At the same time, the strength of the end of the wrapping paper box 1 is ensured, and there is an effect that the operation of pressing the pushing pieces 30 and 31 with a finger to break can be performed stably.
The packaging paper box 1 can be easily flattened by opening the front and rear openings as described above and then pushing down so that the top plate 2, the bottom plate 3, and the side plates 4, 5 are in the same plane. it can.

  Since the unsealing property is improved, the strength is ensured, and it can be easily manufactured, it can be applied to a wrapping paper box for housing a tube container or the like.

It is an expanded view of the packaging paper box of this invention. It is a schematic perspective view of the packaging paper box of this invention. It is a schematic perspective view which shows the folding state of the packaging paper box of this invention.
