Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper packaging box which can be used as an accumulation box for products after opening a box containing a large number of individually packaged products.

[0002]

As this type of packaging box, a front and rear wall plate for forming a box body so that the opened box body can be displayed and stored in an aligned state as a collection box as it is. And, on both sides of the side wall plate, a perforation is formed in the upper and lower two strips to form an opening band around the four-peripheral wall plate, and the opening band is pulled from a cut in the middle, and the box is opened by separating the perforation. What you do is known.

[0003] In the opening of the box with such an opening band,
As the perforation separation progresses, the opening band becomes longer,
As a result, the opening band is easily cut in the middle, or the perforation does not go as expected. Also, the opening band after opening is apt to become garbage, and even as a packaging box before opening, if the fingertip is hooked on the opening band when grasping the box, the perforation is easily cut due to the bending of the opening band and the box body Has problems such as tearing.

[0004] Further, a cut line formed by a single perforation is formed around the four wall plate of the box, and an opening portion of the cut line is formed in an arc shape by detouring the cut line downward on the plate surface of the side wall plate. There is a case where a partition is formed, the arc-shaped plate surface is strongly pushed into the box body, a perforation of the side wall plate is cut off, and a fingertip is applied to a gap created thereby to open the box, but in such a packaging box, The arc-shaped plate surface must be pushed deeply until all the cut lines on the arc-shaped plate surface are cut off and a bent edge due to the pushing is formed at the upper portion of the arc-shaped plate surface. For this reason, if there is not enough room for pushing in the box body, the product inside will be an obstacle to pushing, and it will be difficult to form an opening cue. Therefore, it may not be used for a packaging box for storing a product individually packed in a paper box in a full box.

[0005] The packaging box having the above-mentioned opening means and also serving as an accumulation box is increasingly being used for medical products and pharmaceuticals in addition to individually packaged confectionery and retort foods. In pharmacies and dispensing rooms, medicines are often stored in boxes, so they can be kept in their original storage condition after opening and can be easily taken out of packaging. The box is handy. In particular, in the case of individually wrapped products with heavy contents such as drip solutions, cardboard can be used for the box, so it is very convenient.However, in the past, the box could be damaged unless opened carefully. Or, because of the difficulty in forming the opening cue, it is desired to have a structure that can be opened as easily as possible and furthermore the remaining amount can be easily confirmed.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a packaging box having an opening line with one perforation on at least a three-wall plate of a box body.
The opening clues on the side of the box can be easily opened by pulling the plate surface of the side wall plate. From there, the upper part of the box can be easily opened simply by pulling up or pushing up. An object of the present invention is to provide a new easily-openable packaging box that can be used as an accumulation box for storing while keeping the alignment at the time of storage.

[0007]

SUMMARY OF THE INVENTION The present invention according to the above object has an opening line formed by perforations in a three-walled or four-walled plate of the front and rear wall plates and one of the side wall plates. A packaging box in which the perforations of the front and rear wall plates of the line are continuously formed in the same direction, and the perforations of the one side wall plate are provided in a downwardly convex shape to define an opening tongue piece on the plate surface. The opening tongue is pulled outward, and a finger-hook portion that allows the perforation to be cut off is formed in the plane of the opening tongue.

[0008] Further, the present invention provides that the perforations of the front and rear wall plates of the opening line continuously formed on the three-wall plate are arranged from the upper corner end of the boundary with the other side wall plate to the end of the perforation of one side wall plate. Each of them is formed to be inclined so that the upper part of the box body can be separated and opened upward from the opening line while the other side wall plate remains as it is.

[0009] The perforation line of the opening line in the above configuration is preferably a perforation shape having no jagged edges on the opening edge because it is used as an accumulation box after opening. Further, it is preferable that the opening tongue and the finger hook are weakened by a ruled line to facilitate bending, and the cover plate of the box body is not limited to the one-sided cover but may be a double-sided cover.

According to the present invention, the perforation of the opening line for forming the opening tongue of the side wall plate is detached by hooking a fingertip on a finger hook portion in the plane of the opening tongue. The tongue can be used as a clue for opening, and by simply pulling the upper part of the box upward while holding the fingertip, the upper part of the box can be separated and opened. In this case, the breakage of the side wall plate can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. In the drawing, reference numeral 1 denotes a box, which is an auto-bottomed tuck-in box formed by assembling one paper plate shown in FIG. Receiving flaps 8 and 9 are connected.

The box 1 has an opening line 6 formed by perforations 6a, 6b, 6b on three wall plates 2, 4, 5 extending between one of the side wall plates 2, 3 and the front and rear wall plates 4, 5. Perforations 6a of one side wall plate 2 forming a part of the opening line 6
Is an opening tongue piece 1 which can be used as a clue for opening when separated.
In order to generate 0 on the plate surface, it is curved downwardly convexly, and cuts 11 are formed inward at both ends.
In the plane of the tongue 10 for opening, a finger hook portion 12 is formed in a semicircular shape by perforations 12a, and between the ends of the perforations 6a, 12a is a weakened line 13 of a ruled line for facilitating bending. , 14 are given.

The perforations 6b and 6b of the opening line 6 of the front and rear wall plates 4 and 5 are connected to the end of the perforation 6a of the side wall plate 2 and located at the upper corner end of the boundary with the other side wall plate 3. The upper portion of the box body can be separated from the opening line 6 while the side wall plate 3 is kept as it is.

However, even with such a box 1, the structure of the box itself is not different from that of a normal paper box, so that the lid 7 connected to the rear wall 5 is opened, and A large number of packaged products 30 (see FIG. 3) may be stored vertically and used as a packaging box with the lid closed.

In the box 1 having the above configuration, when the finger hook 12 of the side wall plate 2 is pushed in with the fingertip, the perforation 12a is cut off, and the finger hook 12 becomes a finger hook hole. When a fingertip is hung on the edge of the hole and pulled toward the user, the perforation 6a on the plate surface is cut off, and the tongue 10 for opening by a part of the side wall plate 2 is moved to the position shown in FIG.
As shown in FIG. 7, the sheet is bent from the weakening line 13 and cut out on the side surface of the side wall plate 2.

Subsequent to the cutting of the opening tongue 10, the opening tongue 10 is pulled upward, so that the perforations 6 on the front and rear wall plates 4, 5 connected to the perforation 6a.
b, 6b are separated from the side wall plate 2 side. The perforations 6b, 6b are cut off to the upper corner end of the boundary between the side wall plate 3 and the side wall plate 3 because the other side wall plate 3 is not provided with the perforation line 6. Is left as it is and separated from the opening line 6, and the box 1 is opened.

As a result, in the box 1 used as a packaging box, the top of the box is separated and opened, and the top of the individually packaged product 30 appears in an aligned state from the oblique upper edge 21. The stacking box 20 is obtained.

FIGS. 5 and 6 show front and rear wall plates 4 and 5 of box 1.
This shows another embodiment in which the opening line 6 is circulated around four wall plates of both side wall plates 2 and 3. This opening line 6
The perforation 6a of one of the side wall plates 2 forming a part thereof is convex downward so that an opening tongue piece 10 serving as a clue for opening is formed on the plate surface as in the embodiment of FIG. The perforations 6b, 6b of the opening line 6 of the front and rear wall plates 4, 5 are provided horizontally from the perforations 6a of the one side wall plate 2 to the upper part of the other side wall plate 3. It is continuously formed diagonally toward the perforation 6c.

Also, in the plane of the tongue piece 10 for opening, a finger hook portion 12 is formed in a semicircular shape by a perforation 12a similarly to the above embodiment, and the perforations 6a, 12a are formed.
Between the ends of the line of weakness of the ruled line to facilitate bending 13,
14 is given.

In this embodiment as well, the opening tongue 10 on the plate surface is pulled to form an opening clue, from which the opening tongue 10 is pulled upward, and the opening tongue 10 is pulled to another three-wall plate. The perforations 6b and 6c of the opening line 6 can be separated. As a result, as shown in FIG. 6, the box body 1 used as a packaging box has the upper part of the box body separated and opened, and the upper part of the individually packaged product 30 starts from the upper edge 21 formed obliquely. The stacking boxes 20 appear in an aligned state.

As described above, in any of the above-described embodiments, the perforation 6a that defines the opening tongue piece 10 on the plate surface of the side wall plate 2 is formed by the finger hook 1 in the plane of the opening tongue piece 10.
2 can be pulled open and used as a clue for opening, so that the upper part of the box can be separated and opened. Since the pulling can be performed, the product in the box does not obstruct the opening unlike the conventional one in which the opening cue is formed by pushing. Therefore,
