As the band is cut off, the band becomes longer, which makes it easier to cut the opening band 23 in the middle, or because the perforation 22 does not go as expected. Further, the separated opening band 23 is liable to become garbage, and even as a packaging box before opening, if the fingertip hangs on the opening band 23 when the box body 20 is grasped from above, the perforation 22 is easily formed by bending of the band. There is a problem that the box body 20 is cut and the box body 20 is broken.

[0004] The packaging box having the above-mentioned opening means, which is also used as an accumulation box, is being increasingly 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. Especially in the case of individually wrapped products with heavy contents such as infusion liquids, cardboard can be used for the box, so it is very convenient.However, the conventional one will damage the box unless carefully opened. It is desired to have a structure that can be easily opened as much as possible, and that the remaining amount can be easily confirmed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to form a strip-shaped opening portion in the upper portion of a box so that the opening is facilitated. Another object of the present invention is to provide a packaging box which can be stored in a box as it is while keeping the alignment of the packaging boxes, and also serves as a new easy-to-open stacking box for easily checking the remaining amount.

[0006]

SUMMARY OF THE INVENTION According to the present invention, there is provided a series of opening perforations in which the upper surface of a four-walled plate before, after, and on both sides of a box is formed along the upper edge of the box. , The cut end of the opened portion is formed by perforating the plate surface other than the rear wall plate from the upper edge of the box body, and the cut end is cut at the corner of the upper edge of the rear wall plate. Perforations are provided, and the opening perforations of the front wall plate and the rear wall plate are diagonally provided in the same direction, and the opening edge of the box body after cutting off the opening portion is formed obliquely. It is also a thing.

Further, in the present invention, the upper surface of the four-walled plate before and after forming the box is divided into a band-shaped opening portion by a series of opening perforations provided along the upper edge of the box. The cut end of the opening is formed by perforating the plate surface of the rear wall plate from the upper edge, and thereafter, the upper edge of the wall plate is perforated for cutting.

According to the present invention, when the cut end of the strip is strongly pressed, the perforation is cut, and the cut portion is cut off from the plate surface so as to be pinched by a fingertip, thereby forming an end of the unsealing portion. When the end is pinched and pulled sideways, the perforation for opening and tearing or the perforation for opening and separating is cut off, the perforation for opening the four-wall plate is cut off, and the upper part of the box is separated. Then, the box is opened to form an accumulation box in which the stored products are arranged in an aligned state. In the present invention, since the opened box is used as an accumulation box, the perforation for opening is preferably a perforation having a shape that does not leave a dent at an opening edge of the accumulation box formed by opening.

You will be cut off. As a result, the perforations 9 at the corners are not broken, and when the opening portion 10 that has been cut off is pulled upward as if it were drawn outward, the perforations of the rear wall plate 2, the side wall plate 5, and the front wall plate half are removed. 9 is easily separated and the upper part of the box is completely separated.
The stacking box has the same form as the conventional stacking box shown in FIG.

In the second embodiment shown in FIGS. 5 and 6, the perforations 9 of one of the side wall plates 3 are shifted downward, and the perforations 9 of the other side wall plate 5 are connected to the perforations 9 of the other side wall plate 5. The perforations 9 of the rear wall plate 2 and the front wall plate 4 are obliquely formed in the same direction, and the opening 10 of the front wall plate 4 is provided.
The cut end 11 is formed on one side of the front wall plate 4 closer to the one side wall plate 3 than the gluing position 14 with the lid plate 6 by forming the perforations 12 obliquely from the upper edge, The notch 15 for cutting and raising is cut diagonally along the perforation 12 at the upper edge of the cut end 11 so that the front wall plate 4 can be opened from the side wall plate 3 side.

In such an embodiment, the box body 1 used as a packaging box is, after the opening portion 10 is cut off, a stack in which an opening edge 21 as shown in FIG. The box 20 is formed, and the upper part of the individually wrapped product 40 from the opening edge 21 is an accumulation box 20 in an aligned state.

In each of the above embodiments, the cut end 11 of the opening portion 10 is formed by diagonally forming the perforation 12, but the cut end 11 is omitted in FIG.
May be formed vertically. Also, the position of the cut end 11 may be formed at any position of the side wall plates 3 and 5 other than the front wall plate 4, and even if the formation position is different, there is no change in the sealing and unsealing functions. In the present invention, the formation of the cut end 11 is not limited to the illustrated embodiment.

The third embodiment shown in FIGS. 7 to 9 shows a case in which the cut end 11 of the opening 10 is formed on the rear wall plate 2. The perforation 12 forming the cut end 11 is provided vertically from the center of the upper edge 2a of the rear wall plate to the perforation 9 for opening, and a perforation 16 for separation is provided over the entire upper edge 2a of the rear wall plate. The box 1 can be opened from the back side.

In such a box 1, when the perforation 12 of the cut end 11 is first pressed, a part of the perforation 16 of the rear wall upper edge 2a is cut off together with the perforation 12, and the cut end 11 is cut. Can be cut and raised. Then, when both the cut ends 11 are pulled forward, the perforation 9 of the rear wall plate 2 and the perforation 16 are cut to the corner,
The opening portion 10 of the rear wall plate 2 is cut off in a strip shape, and the upper portion of the rear wall plate is cut open. When a user puts a finger on the upper edge and pulls the box top plate with the lid plate 6 upward, the perforations 9 are formed on both sides. Wallboard 2,
5 is cut off to the front wall plate 4, the upper part of the box is completely separated, and the box 1 is opened. The box 1 after opening is shown in FIG.
It can be used as a stacking box having the same form as the conventional one shown in FIG.

The box 1 according to the present invention has a perforation 9 for opening around the four sides of the box as described above.
Since the structure of the box itself is not different from that of a normal paper box, the lid plate 6 connected to the rear wall plate 2 is opened, a large number of individually packaged products are stored, and the packaging box is closed by closing the lid. It is safe to use it. In addition, a strip-shaped opening portion 10
The upper edge is supported by the lid plate 6 and the flaps 7 and 8 in the closed state, so that it is difficult to bend. Therefore, even if the front and rear surfaces of the box body 1 are gripped and held, the perforation 9 for opening is cut and the box There is no body torn. In addition, since opening only requires separating the upper part of the box, there is no generation of dust like the opening band seen so far.
