Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a packaging paper box, and more particularly to a packaging paper box that is easy to open.

[Conventional technology]

A packaging paper box in which a conventional paper box is formed into a rectangular tube shape, an item is inserted inside, and the item is sealed.It is used to make it easier to open the box and take out the contents, or to print information on the inside, for example. Real table No. 57-500001,
There is a method disclosed in Utility Model Application Publication No. 61-48120.

Figures 3a, b, and c are examples of paper boxes disclosed in Utility Table No. 57-500001.

FIG.
Fold in this order and assemble by joining the adhesive flap and end plate. As shown in the figure, adhesive flaps 8,
Cut lines 17 and 18 connecting the respective corners are provided on the surface of the side plate 2 on which the numbers 9 are connected.

Figure b is an assembly diagram, but when opened, cut line 17
By cutting the sheet and then cutting along the two score lines 18, the package could be opened into a sheet of paperboard as shown in FIG. 3c.

The example shown in Fig. 3 does not open with one cut line cutting operation, but requires three push-cutting operations, which is cumbersome to open, and when printing information on the inside. Even if one side of the side plate 2 where the cut line is printed, it cannot be read after the package is opened, and as a result, the amount of information printed on the box is reduced because it cannot be printed.

An example of Utility Model Application No. 61-48120 is shown in Figure 4. Figure a is a developed front view, and figure b is a perspective view showing an unsealed state after assembly.

As shown in figure a, both sides have inner flaps 1.
0 and 11 are connected in a row, a cut line 19 connecting the two corners of one side adjacent to the other side plate or the inner flap side edge on the outside thereof in the square cylinder forming state is the middle part. A score line 20 is provided on both side edges of the other side plate 4 which is spaced apart from that side and which is adjacent to the side plate 4 and extends over the entire length. FIG. 4b is a perspective view showing the unsealed state after assembly.
By pushing it in further and lifting it, the cut line 2
0 was cut, and the opening was completed in the state shown in FIG. 4b.

However, in the example shown in FIG.
Because of this, the durability against bending of the end plates or inner flaps is significantly reduced. Therefore, when packaging with commonly used automatic paper box packaging machines, the end plates are It is necessary for the inner flap to absorb a certain amount of load, which can cause problems, and in extreme cases, during the subsequent flap folding and forming process.
There was a problem in that the end plate or inner flap could be cut, and special measures were required in the packaging machine to implement it.

In addition, in terms of practicality, the cut line provided on the end plate or inner flap part is far from the point of application to start opening, so the breakage at the cut line does not proceed as expected, causing the box to deform. There are also points.

[Problem that the invention attempts to solve]

In order to solve the above-mentioned problems, the purpose of the present invention is to provide a packaging paper box that can be easily opened and the contents can be easily taken out, and which also has information on the inner surface of the paper box. To provide a packaging paper box that is easy to read when printed.

[Means for solving problems]

The above object of the present invention is to, in the packaging paper box shown in FIG. This was achieved by a packaging paper box characterized by having a score line 16 that again intersects the fold line and extends to the gluing allowance.

〔Example〕

FIGS. 1a and 1b are developed front views of one embodiment of the packaging paper box according to the present invention.

In Fig. 1a, side plates 1, 2, 3, 4 connected via fold lines 14, 15, gluing allowance 5, inner flaps 10, 11, 12, 13, adhesive flaps 8, 9
A packaging paper box is assembled using paperboard made of.

First, the gluing allowance 5 and the side plate 1 are joined and formed into a rectangular tube shape, and then articles are inserted inside and the inner flaps 10, 12, 11, 13, adhesive flaps 8,
9. The end plates 6 and 7 are joined to seal the article.In the present invention, from the fold line 15 that constitutes the gluing allowance and a part of the outer edge, the fold line 1 is
5 and extends to the side plate 4, and after intersecting the fold line 15 again, it has a score line 16 that reaches the outer edge.

A similar packaging paper box can also be assembled using an exploded view as shown in FIG. 1b.

FIG. 2a is a perspective view of the assembled paper box. When taking out the contents of the paper box, the side plate 1 is cut by pulling the cut line 16 toward the push-cut side plate 1. The inner flap 1 peeled off from the glue area 5 and the adhesive surface of the side plate 1 along with the part surrounded by the line of sight.
0 and 11, the package could be easily opened, and the contents could be easily taken out.

FIG. 2b is a perspective view showing the state in which the package is opened in this manner.

Furthermore, when information was printed on the inner surface of the packaging paper box of the present invention, it was possible to read it even if it was printed on any of the side panels except for the part for gluing.

[Effect of idea]

The cut line guides the fracture surface when the rupture progresses to the adhesive surface which has the lowest strength among the parts constituting the square tube of the paper box of the present invention, and ensures that the square tube breaks from the adhesive surface, Compared to the conventional technique of creating a score line on the side plate, it is possible to reduce the length of the score line on the side plate by half or less, and it is possible to reduce the length of the score line on the side plate by half or less, and it is possible to reduce the length of the score line on the side plate by 1/2 or less. Since it can be inserted, the breakage at the cut line is ensured and the breakage does not proceed to the side plate parts other than the cut line.

Therefore, when printing information on the inner surface of the box, it is possible to print information on the area excluding a portion of the gluing allowance from the four sides of the side panels.

Furthermore, the length of the score line on the side plate is short, and the area surrounded by the score line and crease line is also small, so before forming the square tube, items can be inserted into the paper box in the form of a two-fold flat plate and sealed. In the packaging process, there is no problem when packaging with currently commonly used packaging machines, and the hindrance to design and design printing on the box surface can be kept to a minimum.

Thus, according to the present invention, it was possible to provide a packaging paper box that is easy to open, easy to take out the contents, and easy to read when information is printed on the inner surface of the paper box.
