In addition to printing ink, the printing unit 74 is provided with display and decoration by various means such as surface treatment of unevenness.

  Next, an example of an assembly method of the packaging box 10 of this embodiment will be described. Here, FIG. 3 is a view of the surface of the box-forming piece 12. The folding method in which the surface of the box-forming piece 12 is convex is referred to as normal folding, and the folding method in which the back surface is convex is referred to as reverse folding. .

  First, the glue 76 is applied to the surface of the glued piece 22. The glue 76 is applied in a pair of straight lines along the crease line 30 and the side edge portion 22a of the glued piece 22, and the portion surrounded by the zipper line 68 and the extended line of the cutting line 70 is avoided and is not applied. Next, the crease line 28 is folded forward and the crease line 24 is folded forward. Thereby, the surface of the glued piece 22 is glued to the back surface of the side surface 14. The box-forming piece 12 is in a folded state, and is shipped in this folded state.

  Thereafter, the crease lines 24, 26, 28, and 30 are each normally folded at 90 ° to form a rectangular box in a factory or the like for storing and packaging the contents. The flaps 32 and 40 are normally folded at the crease lines 34 and 42 at one opening of the cylinder assembled from the side surfaces 14, 16, 18 and 20, and then the inner lid piece 44 is folded at the crease line 46. To do. Then, paste 78 is applied to the back surface of the outer lid piece 36. The glue 78 is applied linearly along the end of the outer lid piece 36 opposite to the crease line 38. The outer lid piece 36 is normally folded at 90 ° by the crease line 38, whereby the back surface of the outer lid piece 36 is glued to the surface of the inner lid piece 44, and one opening of the packaging box 10 is closed. In this state, the contents are put into the box from the other opening, and the flaps 32 and 40 are similarly folded along the crease lines 34 and 42, and the inner lid piece 44 is folded forward along the crease line 46. Then, paste 78 is applied to the back surface of the outer lid piece 36, the outer lid piece 36 is normally folded at 90 ° along the crease line 38, and the other opening of the packaging box 10 is closed. Thereby, packaging is completed as shown in FIG.

  The glued piece 22 is located on the back side of the side surface 14, the glued piece 22 is exposed from the slit 52 and the opening through hole 54, and is reliably packaged without communicating with the inner space of the packaging box 10. . Further, the paste piece 22 is provided with a printing portion 74 different from the side surface 14 so that the positions and shapes of the slit 52 and the opening through-hole 54 are visually easy to understand, and the end portion 71a of the cut portion 71 can be easily confirmed. The Since the slit 52 and the opening through-hole 54 are stepped from the surface of the side surface 14, the position and shape can be recognized by touch when touched by a hand.

  In addition, the cut lines 58 formed on the opening lines 50 and 48 on the side surfaces 16, 18, and 20 have a strong impression with a continuous circular shape, and are visually easy to understand. When the cut line 58 is touched by hand, a portion surrounded by the cut line 58 is pushed into the box to form a step, and the continuous portion of the step is touched by hand so that the position, shape, and length of the excision part 71 are increased. Easy to understand by touch. The crease line 30 between the side surface 20 and the glued piece 22 has a portion where a pair of crease lines 72 are provided on both sides of the crease line 30 and the pair of crease lines 72 are bent at an obtuse angle. The ridgeline formed by the crease line 30 has a chamfered shape, and the end 71a of the cut portion 71 is located in the chamfered portion, and a space is created between the end 71a and the glued piece 22 for easy holding. Become.

  When taking out the contents from the packaging box 10, first, the end portion 71 a that is held to remove the cut portion 71 is searched. Since the slit 52 and the opening through-hole 54 are easy to understand visually and tactilely, the position and shape of the end portion 71a can be confirmed even by a person with reduced visual acuity. When the end portion 71a is held and pulled up, the gap between the pair of slits 52 is easily caused, and when further pulled up, the gap between the opening through holes 54 is cut and the side surface 14 is divided. The cutting line 56 passes the ridge line bent by the crease line 24 and reaches the side surface 16, and is further lifted with respect to the side surface 16 so that the portion between the cutting lines 58 is cut so that the cutting lines 58 are continuous. And the side surface 16 is divided. At this time, a convex portion 80 is continuously formed on the side surface 16 by the circular uncut portion 60 at the side edge portion where the cut portion 71 is removed by the cut line 58. Further, the cut portion 71 is pulled up and divided with respect to the side surface 18, and the side surface 20 is divided in the same manner. A sound is generated each time the opening through holes 54 or between the cut lines 58 are cut, and it is confirmed by hearing that the cuts are made. The packaging box 10 is in a state in which the two divided parts are connected by the glued piece 22 and is opened to take out the contents. Furthermore, the zipper wire 68 of the glued piece 22 may be cut to take out the contents in the separated state shown in FIG.

  According to the packaging box 10 of this embodiment, the position and shape of the excision part 71 are easy to understand by visual and tactile sense with a simple structure, and a relatively sound is generated when opening, and the opening can be confirmed by hearing. . Thereby, it can open easily also to the person whose visual acuity fell. Moreover, since the printing part 74 different from the side surface 14 is visible and conspicuous from the slit 52 and the opening through-hole 54, the end part 71a of the excision part 71 is easier to understand and can give a strong impression to the consumer. The opening through-hole 54 and the cut line 58 are rounded and have high decorativeness. Since the opening through-hole 54 is formed larger near the end 71a of the cut portion 71, it is easy to cut from the end 71a. The cut-out portion 71 has a space between the end portion 71a and the glued piece 22 and is easy to hold, and since it is sandwiched between the slits 52, it is easy to start pulling up and can be opened even for people who have difficulty with their hands. It is easy. The opening lines 48 and 50 are provided with cutting lines 56, 62, 64, and 70 at the corners between the side surfaces that intersect the crease lines 24, 26, 28, and 30 that are ridge lines of the corners. Therefore, it can cut smoothly beyond the ridgeline. A sound is generated each time the opening between the opening through holes 54 or between the cut lines 58 is cut when opening, so even a person with reduced visual acuity can confirm opening by hearing. .

  Furthermore, after opening the packaging box 10 of this embodiment, the circular convex part 80 is continuously formed in the side edge part from which the cutting part 71 was removed, and it can give decorating property. Moreover, since the convex part 80 is a curve, even if it touches with a hand, there is no possibility of injury and it is safe. Irregularly small protrusions are formed in the portion where the box-forming piece 12 is broken, but the portion obtained by cutting the box-forming piece of this embodiment is located in the valley between the pair of convex portions 80. It is safe without touching it. After cutting the zipper wire 68 of the glued piece 22, irregular small projections are formed, but since they are located on the back surface of the side surface 14, they are safe without touching them. Since the distance between the cut lines 58 in the diametrical direction parallel to the opening lines 48 and 50 is the shortest distance, the box-forming piece 12 is cut in the diametrical direction and cut cleanly without leaving the side. be able to.

  Note that the packaging box of the present invention is not limited to the above embodiment, and the size and shape of the box can be appropriately changed according to the shape and number of the contents, and the position of each unsealing line and The number of opening holes and cut lines provided in each opening line can be appropriately changed according to the box. The opening line may be provided on the upper surface or the like in addition to the side surface, or may be provided only on one side surface. In addition to boxes, it can be used for various types of packaging such as envelopes. The shape of the score line may be other than the above-described embodiment, and may be provided with different sizes, as long as it cuts reliably. The printing part of the glued piece can be designed freely, and a pattern may be provided even on a plain.
