Description

[Detailed Description of the Invention] The present invention relates to a paper box that can be easily unpacked and that can form a relatively complicated pattern on the paper box body after unpacking.

Paper boxes are already known which are provided solely with a zipper or cut line formed by two rows of intermittent score lines.

By the way, if a zipper or cut line is provided on the side plate,
A method of unpacking in these parts (so-called seppuku type)
With conventional paper boxes, it has not been possible to form complex patterns on the paper box body after unpacking. This is because if the zipper on the paper box has a complicated shape, tears may occur in areas other than the cut lines when it is peeled off, causing the zipper to taper and damaging the paper box itself. Furthermore, if an attempt was made to unpack a paper box using only the cut lines, it would be extremely difficult to unpack, and at the same time, tearing would easily occur in areas other than the cut lines.

In view of the above-mentioned current situation, the inventors of the present invention thought that it would be beautiful and interesting to the taste if a pattern that matched the pattern was formed on the paper box body after the paper box was unpacked. Thought. That is, an object of the present invention is to provide a paper box that can be easily unpacked without tearing, etc., and that can form a complicated pattern on the paper box body after unpacking.

The inventors of the present invention have conducted various studies on paper boxes in order to achieve the above objectives, and have found that, in particular, when a combination of zippers and cut lines are installed on the side panels of paper boxes,
The paper box is first opened with a zipper, and then it is better unpacked by cutting off the remaining cut line. I learned that the strength against compression and vibration is greater than the conventional one that only has a

The present invention was made based on the above findings, and the gist thereof is that two rows of intermittent T-shaped or approximately T-shaped cut lines are formed on the side plate along its circumferential direction. A strip-shaped zipper and a cut line forming a pattern of an arbitrary shape are provided, one end of the cut line substantially joins a starting notch at one end of the zipper, and the other end of the cut line The end portion is a paper box provided so as to substantially join each of the two rows of score lines at the other end of the zipper.

Hereinafter, the structure of the paper box of the present invention will be explained based on the drawings.

As shown in FIGS. 2 and 3, the side plate 2 of the paper box 1 of the present invention is provided with a zipper 3 and a cut line 4 connecting with the zipper 3 along the circumferential direction of the side plate 2.

First, the zipper 3 is formed by two rows of intermittent score lines 5, and as shown in FIG. It consists of a straight part 7 that communicates with the cut line 5 of the.

In this invention, the cut line 5 forming the zipper 3 is
The shape is T-shaped or approximately T-shaped. By forming the cut lines 5 that form the zipper 3 as described above, the zipper 3 can be shaped like a conventional zipper.
Compared to the Y-shaped case, the parts other than the cut line 5 are less likely to be torn, the cuts after peeling off are not irregular and beautiful, and the strength of the paper box 1 against compression and vibration is reduced. Less is.

Further, at the beginning of the zipper 3, a starting notch 9 of an appropriate shape is provided, preferably starting from the crease 10. In this case, the starting notch 9 is raised at the crease 10, making opening easier.

In addition, as shown in FIG. 3, the width between the cut lines 5' formed on the zipper 3 in front of the part overlapping with the adhesive piece 11 is determined by the width of the cut line 5' formed on the adhesive piece 11. It can also be made slightly narrower than the width between the zipper 3 and the adhesive piece 1.
Even if the cut lines 5 formed on the zipper 1 are attached with a slight deviation, the peeling force is reliably transmitted between the cut lines 5'', and the zipper 3 can be peeled off well.

In addition, as shown in FIG. 3, at the part where the zipper 3 joins with the cut line 4 described below, for example, the straight part 7-a of the cut line 5 of the zipper 3 is formed into a curved shape toward the cut line 4. You can also. In the above case, the tear is smoothly transmitted from the zipper 3 to the cut line 4. In addition, zipper 3 is
Unless the shape is particularly complicated, it may be provided at an angle with respect to the bottom surface of the paper box 1.

Next, the cut line 4 provided on the paper box 1 of the present invention
is formed by, for example, a single line cut, a perforation line, or a combination thereof. In the present invention, the cut line 4 is provided in an arbitrary shape, for example, along the outline of the pattern 12 drawn on the paper box 1.
In this case, if the cut line 4 is provided with a combination of a notch in a relatively large curved part and a perforation line in a small curved part, tearing is less likely to occur in the part other than the cut line 4.

The zipper 3 and the cut line 4 are such that one end of the cut line 4 is substantially connected to the starting notch 9 at one end of the zipper 3, and the other end of the cut line 4 is connected to the other end of the zipper 3. It is provided so as to be substantially joined to each of the two rows of cut lines 5 at the end portion of.

Further, the paper box 1 of the present invention is not limited to the hexahedral shape shown in the drawings, but can have various shapes. Also,
As for the material of the paper box 1, a wide variety of materials can be used, such as ordinary cardboard and corrugated cardboard.

When unpacking the above-mentioned paper box 1, first peel off the zipper 3 from the starting notch 9 to the part where it joins the cut line 4, and then remove the remaining cut line 4 by pulling the lid. Cut by operation.

As described above, the paper box of the present invention can be opened smoothly using the zipper, and can be cut and unpacked by a simple operation along the cut line. In addition, the paper box body after unpacking is formed with a pattern that matches the design, making it beautiful and highly palatable, and making it easy to take out the stored items. Furthermore, it has greater resistance to compression and vibration than conventional zippers that only have a zipper.
