  However, in the packaging box opening means as described above, for example, in the case of a packaging form in which a partition is sandwiched between products, the partition becomes an obstacle and the tongue piece 55 can hardly be pushed in, which makes it difficult to open the package. There is.

  In addition, a tear strip made of cut tape or liner cut is provided around the entire outer wall of the packaging box, and an H-shaped cut is made in the outer wall as the starting end, the inside of the cut is pushed in, the tear strip is pulled, and the outer wall is cut Even with the opening means, there is a problem that it is difficult to push the starting end portion.

  Then, this invention makes it a subject to make it easy to open a packaging box irrespective of the shape and packaging state of a content.

  In order to solve the above problems, in the present invention, a cut line is provided on the outer wall of the packaging box, and a pressing portion facing the cutting line is provided, and a finger is inserted into a finger hole formed along with the pressing of the pressing portion, and the outer wall is By pulling outward, the cut line is broken and the outer wall is opened. In the opening means of the packaging box, a straight line is bent between the adjacent tops of the same phase of the cut line that has the corrugated cut line. A fold line-shaped mountain fold line is inserted and formed at the part between the cut line and the mountain fold line, and a valley fold line is inserted from the bent part of the mountain fold line to the top of the opposite phase of the cut line in the middle part of the indentation It was.

  In the packaging box provided with the opening means according to the present invention, even if the pushing portion facing the wavy cut line is pushed, the pushing portion does not go so deeply into the box that a finger can be sufficiently inserted by a small pushing portion. The packaging box can be opened by putting a finger into the finger hole and pulling the outer wall outward to break the score line.

  In addition, since the score line facing the pushing portion is wavy, when the side plate is pulled, it is difficult for pressure to act locally on the finger and it is difficult to feel pain on the finger.

  Further, no dust is generated after opening as in the case of opening means by a cut tape or liner cut.

  In addition, the packaging box provided with the opening means does not need to be attached with a cut tape or a liner cut, and can be manufactured at a low cost by using a flexo-glue die cutter that performs printing and gluing.

  First, a cardboard packaging box provided with an opening means according to a first embodiment of the present invention will be described with reference to FIGS.

  In the packaging box blank shown in FIG. 1, the width and long side plates 1 and 2 forming the surrounding outer wall are alternately arranged, and the bottom and top surfaces of the packaging box are closed at the lower and upper ends of the side plates 1 and 2. The flaps 3 and 4 are continuously provided. In addition, a passage piece 5 is connected to the outer edge of one side plate 2.

  On one side plate 1, a continuous wave-like cut line 6 that travels in the lateral direction is inserted as a means of opening up to a position slightly away from the boundary with the side plate 2. It is put to the boundary with three. The cut line 6 is a zipper type in which curved cuts are intermittently connected via a connecting portion, and the cut line 7 is mainly a zipper type in which hook-shaped cuts are intermittently formed.

  Further, as shown in FIG. 2, the side plate 1 is provided with a pushing portion 8 facing each of the wave forming portions at both ends of the score line 6. The pushing portion 8 is formed in a portion sandwiched between the score line 6 and the mountain fold line 9 by inserting a fold line-shaped mountain fold line 9 having a straight line between adjacent tops of the same phase of the score line 6. .

  A valley fold line 10 is inserted from the bent portion of the mountain fold line 9 to the top of the opposite phase of the score line 6 in the intermediate portion of the pushing portion 8.

  Here, the mountain fold line 9 is a ruled line entered from the back side of the cardboard, and the valley fold line 10 is a ruled line entered from the surface of the cardboard.

  When assembling a packaging box from such a blank and packaging a packaged item with a cap E containing a campaign prize on the head of a beverage can C as a product, as shown in FIG. The side plates 1 and 2 are bent into a square tube shape, the passage piece 5 is attached to the opposite side plate 2 to form a peripheral wall, and the bottom side flaps 3 and 4 are sequentially bent and bonded together to close the bottom surface.

  Then, a cardboard pad 12 is laid on the bottom of the packaging box, the cans C with caps E are arranged in a predetermined arrangement, the cardboard partitions 11 are sandwiched between the cans C in each row, and the caps E A cardboard pad 13 is placed on the upper surface, and the top surface side flaps 3 and 4 are sequentially folded and bonded together to close the top surface.

  On the other hand, as shown in FIG. 4, when the packaging box is placed vertically with one side plate 1 facing upward and the can C with the cap E is taken out of the packaging box, as shown in FIG. The part 8 is pushed in, the part which faces the pushing part 8 of the score line 6 is broken, and a finger is inserted into the finger hole formed along with the pushing.

  Next, as shown in FIG. 6, after putting a finger on the edge of the pushing portion 8 and pulling one of the cut lines 6 of the side plate 1 outward to open, the other of the cut lines 6 as shown in FIG. Hang your finger on the edge and pull outward to release. When the side plate 1 is thus opened, the can C with the cap E can be taken out from the opening.

  Further, even when the packaging box is placed horizontally with the flaps 3 and 4 as the bottom surface, it can be opened as in the case of placing it vertically.

  In such an opening means, when the pushing portion 8 is pushed in, the pushing portion 8 does not enter the box so deeply that the small pushing portion 8 avoiding the position of the inscribed portion of the can C and the partition 11 in the side plate 1. Even so, it is possible to form a finger hole into which a finger can sufficiently enter.

  Moreover, since the score line 6 that faces the pushing portion 8 is wavy, when the side plate 1 is pulled, it is difficult for pressure to act locally on the finger and it is difficult to feel pain on the finger.

  Further, no dust is generated after opening as in the case of opening means by a cut tape or liner cut.

  In addition, the packaging box provided with the opening means does not need to be attached with a cut tape or a liner cut, and can be manufactured at a low cost by using a flexo-glue die cutter that performs printing and gluing.

  In the above embodiment, the cut line 6 is composed of a plurality of continuous waves, and the cut line 7 extends in the orthogonal direction from both ends thereof. However, like the unsealing means according to the second embodiment shown in FIG. Alternatively, the score line 6 may be one wave and the score line 7 may extend obliquely from both ends thereof.

  Further, the cut line 7 may extend not only in the direction in which the pushing portion 8 is pushed and pulled as it is when the outer wall is cut, but also in the direction in which the finger is placed on the opposite edge and pulled.

  Moreover, you may make it the cut line 7 extend in parallel toward one of the orthogonal directions from the both ends of the cut line 6 of one wave like the opening means which concerns on 3rd Embodiment shown in FIG.

  Furthermore, like the opening means according to the fourth embodiment shown in FIG. 10, the cut line 7 may be continuous from both ends of the cut line 6 of one wave so as to draw a plurality of arcs.

  In addition, the valley fold line 10 may be placed in a V-shape or Y-shape that is bifurcated from the bent portion of the mountain fold line 9 to the top of the opposite phase of the score line 6, or may be placed in parallel. .
