Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a packaging box that accommodates merchandise without a gap, and relates to a packaging box with an opening that has a function of facilitating the opening of a box in which an insertion piece is glued to the back surface of a side surface.
[0002]
Conventionally, there are packaging boxes that are stored and transported and displayed as they are in stores or used in hospitals, pharmacies, etc., and such packaging boxes are integrally punched from a single blank sheet. This is an assembly of the extracted box-forming pieces. This box-forming piece has four side surfaces connected in parallel, lid pieces formed at both end portions of the one side surface, and end portions of the side surfaces facing each other without being adjacent to the side surface on which the lid piece is formed. Is provided with an opening formed by a substantially square sewing line having an end portion as a base point. And two pairs of flaps are provided at both ends of the side surface adjacent to the side surface on which the lid piece is formed.
[0003]
In this method of assembling the packaging box, the glued pieces are glued to the back surface of the opposite side surface, and each side surface is bent to 90 degrees and assembled into a square box. Then, a pair of flaps at one end of the box is folded at 90 degrees with respect to the side surface, the lid piece and the insertion piece connected to the lid piece are folded, glued to the insertion piece, and opposed to the side surface on which the lid piece is formed Insert the plug inside the side to be closed. And after accommodating the contents, the other end of the box is also closed.
[0004]
[Problems to be solved by the invention]
In the case of the above-described conventional technique, since the insertion piece is glued on both sides, the lid piece is opened by pushing the opening with a finger and breaking the sewing machine wire. At this time, when the contents are stored without a gap, even if the opening is pushed with a finger, the opening cannot be pushed into the box body, and the sewing machine wire may not be broken.
[0005]
The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a packaging box having an effect of facilitating opening with a simple structure.
[0006]
[Means for solving problems]
The present invention comprises a box-forming piece integrally punched from one blank sheet. The box-forming piece includes a plurality of side faces, a lid piece formed at one end of the side face, An insertion piece connected to the lid piece and positioned on the side opposite to the side surface, and a notch formed at both ends of the crease line separating the lid piece and the insertion piece and slightly closer to the insertion piece; A flap connected to the end of each side surface adjacent to the side surface on which the lid piece is formed and overlapped with the lid piece, and provided at an edge portion facing the notch of each flap, and locked to the notch. that projections and are mounted on the two folding ruled lines located on either side of the side surface opposite the side surface of the lid piece is formed, the length reaching the vicinity of the distal end of the insertion piece as a base point to the end of the side surface with the perforation lines are provided is, etc. end of its perforation line Folding borders or intermittent cut lines box for it are open port with packaging provided in the side surface connecting the teeth.
[0007]
In the packaging box with an opening according to the present invention, a portion surrounded by a crease line connecting the sewing line provided on two crease lines and the end points of the sewing line becomes an opening. The product is accommodated, glue is applied to the insertion piece, and the inner surface of the opening is glued and sealed. When opening the packaging box, open the package by hooking your finger to the end of the opening, breaking the machine line, using the crease line connecting the end points of the machine line as a fulcrum, and removing the glue from the insert Can do.
[0008]
Unlike the conventional opening, the opening is not pushed into the box, but is pulled outward to open it, so that it can be opened easily even when the contents are tightly packed in the box.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a packaging box 10 with an opening according to an embodiment of the present invention. As shown in FIG. 1, the packaging box 10 has a box-shaped piece 12 made of paper or plastic. It is formed by punching a blank sheet.
[0010]
The box-forming piece 12 is formed by integrally connecting side surfaces 14, 16, 18, and 20. Further, a glued piece 22 that is glued to the inside of the side surface 14 in an assembled state is formed to be connected to the side of the side surface 20. The side surfaces 14, 16, 18, 20 and the glued piece 22 are divided by crease lines 24, 26, 28, 30, respectively.
[0011]
A lid piece 40 is connected to the end of the side surface 16, and an insertion piece 44 is provided on the lid piece 40 via a crease line 52. The lid piece 40 is separated from the end of the side surface 16 by a crease line 48. A lid piece 42 is connected to the other end of the side surface 16, and an insertion piece 46 is provided on the lid piece 42 via a crease line 54. The lid piece 42 is separated from the end of the side surface 16 by a crease line 50.
[0012]
A flap 60 is connected to the end of the side surface 14, and the flap 60 is separated from the side surface 14 by a crease line 68. A flap 62 is connected to the other end of the side surface 14, and the flap 62 is separated from the side surface 14 by a crease line 70.
[0013]
A flap 64 is connected to the end of the side surface 18, and the flap 64 is separated from the side surface 18 by a crease line 72. A flap 66 is connected to the other end of the side surface 18, and the flap 66 is separated from the side surface 18 by a crease line 74.
[0014]
The crease lines 28 and 30 are sewing lines 80 and 82 with the end portion as a base point, and a crease line 84 that crosses the side face 20 is provided by connecting the end points of the sewing lines 80 and 82.
[0015]
Next, a method for assembling the packaging box 10 of this embodiment will be described with reference to the drawings. Here, FIG. 1 is a view of the front side of the box-forming piece 12, and a folding method in which the front side of the paper surface is convex in FIG. 1 is referred to as normal folding. First, the paste 32 is applied to the paste piece 22. The crease lines 24 and 28 are normally folded, and the back surface of the side surface 14 is glued to the surface of the glue piece 22.
[0016]
Next, the crease lines 24, 26, 28, and 30 are each normally folded so as to be 90 degrees to form a rectangular box. The flap 62 is folded forward 90 degrees along the crease line 70, and the flap 66 is folded forward 90 degrees along the crease line 74. The paste 32 is applied to the surface of the insertion piece 46, the insertion piece 46 is folded forward along the crease line 54, the lid piece 42 is folded forward along the crease line 50, and the insertion piece 46 is inserted inside the side surface 20. Glue the inside of the side 20.
[0017]
Next, the product is inserted into the box from the end of the box that is not sealed. Thereafter, the flap 60 is folded forward at 90 degrees along the crease line 68 and the flap 64 is folded forward at 90 degrees along the crease line 72. The paste 32 is applied to the surface of the insertion piece 44, the insertion piece 44 is normally folded at the crease line 52, the lid piece 40 is normally folded at the crease line 48, and the insertion piece 44 is glued to the back surface of the opening 86. It is attached.
[0018]
Next, the case where this packaging box 10 is opened is demonstrated. When taking out the merchandise stored therein, it can be opened by first putting a finger on the end of the seal 86 and tearing off the sewing wires 80 and 82 and peeling off the glue with the insertion piece 44.
[0019]
【The invention's effect】
The present invention has a simple structure and facilitates opening when the contents are accommodated without gaps and when the insertion piece is glued to the back surface of the side surface. The pattern of the sewing lines 80 and 82 can be changed as appropriate, and the same effect can be obtained without any problem even if the folding line 84 is changed to a sewing line or the like.
