Description

  The present invention relates to a packaging body such as a packaging box or an envelope, and a ruled line structure for opening a sealing sticking allowance in the packaging body.

  The packaging box includes an outer peripheral wall having a pair of side walls and end walls. Inner flaps are connected to the side walls, and outer flaps are connected to the end walls. And the opening part of an outer peripheral wall bends an outer flap (sticking margin for sealing) after folding an inner flap (sticking wall), and sticks these with the adhesive which consists of hot-melt resin (hot melt). Is sealed. The envelope includes an outer peripheral wall composed of a front surface and a back surface, and a flap (sealing sticking margin) is continuously provided on the front surface. And the opening part of an outer peripheral wall is sealed by sticking the sticking allowance for sealing on the back surface (to-be-adhered wall).

  These packaging bodies such as packaging boxes and envelopes have the effect of being able to reliably maintain the sealed state because the adhesive margin for sealing is adhered to the adherend wall with an adhesive, but the difficulty in opening work is poor. There is.

  Therefore, in the packaging box of Patent Document 1, folding lines extending obliquely from the front edge to the side edge are provided on both sides of the front end of the outer flap, which is the sealing margin, and the front corner of the outer flap has a triangular shape. A gripping part is formed. Since the user can grip the grip portion and pull the outer flap outward, the opening workability is improved.

  Moreover, in the packaging box of patent document 2, it is a side wall which continues from the starting point of a front-end edge so that it may be located in the center side with respect to the sticking part with one inner flap in the outer flap which is the sticking allowance for sealing. A folding curve for assisting opening is provided to extend toward the boundary line. As a result, the user grasps the center portion of the outer flap and pulls it outward to peel off the side of one of the inner flaps while breaking the folding assist folding curve. Can be peeled off. That is, the opening force is applied so that one of the pair of sticking portions is peeled off, and then the other is peeled off after opening one. As a result, the opening can be performed with a small force, and the opening workability is improved.

  Although these packaging boxes of Patent Documents 1 and 2 can improve the opening workability of the outer flap, which is the sealing allowance for sealing, there is still room for improvement in labor saving of the opening work.

The bill is peeled from the sticking part (R). For this reason, since the sealing allowance for sealing can be peeled off using the so-called lever principle, labor saving regarding the opening operation can be achieved, and the opening workability can be surely improved.

  In this package, it is preferable that the folding assist folding curve is composed of a curved line in which the distance from the sticking portion (R) gradually approaches the sealing sticking portion (P2). If it does in this way, even if it is a site | part (action point) farthest from the holding | grip part (power point), the sticking part (R) will peel gradually from the tip edge side of the sticking allowance for sealing, and is small. It can be peeled off with force.

  And a pair of second wall portions adjacent to the first wall portion and having a lateral width shorter than that of the first wall portion, and each of the first wall portions is covered with the cover. Adhering walls are continuously provided, the sealing margin for sealing is connected to each second wall portion, and both side portions of the sealing margin for sealing are attached to the adherend wall by the adhesive portion (R). It is preferable that it is stuck. If it does in this way, after peeling off the sticking part (R1) on the side close to the gripping part, the sticking part (R2) on the far side is subsequently used with the boundary line between the sealing allowance for sealing and the end wall as a fulcrum. It can be peeled reliably with a small force.

  In the packaging body and the ruled line structure for opening of the present invention, the folding assist folding curve located on the opposite side of the holding part (R) with respect to the gripping part is used as a fulcrum, and so-called lever application is used for sealing. Since the dressing allowance can be peeled off, labor saving regarding the opening operation can be achieved, and the opening workability can be surely improved.

These are provided so as to be alternately and linearly continuous in the lateral direction. Among these, the margin part 13 for adhering to the side wall 11B located in the right end part is connected to the side edge of the end wall 12A located in the left end part. The boundary portion between the end wall 12A and the side wall 11A, the boundary portion between the side wall 11A and the end wall 12B, the boundary portion between the end wall 12B and the side wall 11B, and the boundary portion between the glue margin 13 and the end wall 12A are respectively A first folding line 14 is provided which is formed with a ruled line from the back liner 3 side so as to compress the thickness.

  The side walls 11A and 11B are the first wall portions of the present invention that face each other in the assembled state. The end walls 12A and 12B are the second wall portions of the present invention that are adjacent to the side walls 11A and 11B and face each other in the assembled state. And end wall 12A, 12B which is a 2nd wall part is formed in the dimension whose lateral width is shorter than side wall 11A, 11B which is a 1st wall part. Note that the outer peripheral wall of the packaging box 10 of the present embodiment has a quadrangular shape in plan view having a pair of side walls 11A and 11B and end walls 12A and 12B, but a surface between the walls 11A, 11B, 12A and 12B. It may be an octagonal shape in plan view provided with a take-up wall.

  Upper side inner flaps 15A and 15B are connected to the upper ends of the side walls 11A and 11B, and lower side inner flaps 16A and 16B are connected to the lower ends. On the end walls 12A and 12B, upper outer flaps 17A and 17B are connected to the upper end, and lower outer flaps 18A and 18B are connected to the lower end. A second folding line 19 similar to the above is provided at the boundary between these walls 11A, 11B, 12A and 12B.

  The upper flaps 15A, 15B, 17A, and 17B constitute a canopy that seals the upper end opening 20 (see FIG. 4) of the outer peripheral wall, and the lower flaps 16A, 16B, 18A, and 18B are lower end openings ( A bottom wall for sealing (not shown) is formed. Each of the flaps 15A, 15B to 18A, 18B is protruded with a dimension setting in which the leading edges of the flaps 15B, 15A-18B, 18A facing each other in the sealed state are abutted. The outer flaps 17A, 17B, 18A, and 18B have a narrower lateral width than the inner flaps 15A, 15B, 16A, and 16B by setting the widths of the end walls 12A and 12B.

  In the present embodiment, the outer flaps 17A, 17B, 18A, 18B constitute a sealing sticking allowance for maintaining the opening 20 in a sealed state. Moreover, inner flap 15A, 15B, 16A, 16B comprises the to-be-adhered wall by which the both sides of outer flap 17A, 17B, 18A, 18B are stuck to an outer surface side by sticking part R1, R2. Adhesion part R1, R2 is comprised with the adhesive agent which consists of hot-melt resin (hot melt). In addition, since the outer flaps 17A, 17B, 18A, and 18B of the present embodiment have a narrow lateral width and a long projecting dimension, the sticking portions R1 and R2 extend from the second folding line 19 toward the leading edge. It is comprised so that a shape may be made.

  The outer flaps 17A, 17B, 18A, and 18B, which are sealing margins, are provided with opening ruled lines having grip folding curves 21A and 21B and opening assist folding curves 23A and 23B. In the present embodiment, these are constituted by reverse rules formed by putting rules from the front liner 2 side. However, the configuration is not limited to the reverse ruled line, but the same folding line as described above with the ruled line from the back liner 3 side, the half cut line (half cut line) obtained by cutting the front liner 2 or the back liner 3, and the folding line. You may comprise by the lead ruled which provided the cutting line with the predetermined space | interval.

  As shown in FIG. 7, the folding curves 21A and 21B for gripping are from the part P1 located on the extension line of the sticking parts R1 and R2 at the tip edges of the outer flaps 17A, 17B, 18A, and 18B. The outer flaps 17A, 17B, 18A, and 18B located on the outer side of R2 are provided so as to extend at an angle of about 45 degrees toward the portion P3 on the side edge of the outer flaps 17A, 17B, 18A, and 18B. By the folding curves 21A, 21B for gripping, gripping portions 22A, 22B having a right isosceles triangular shape are formed at the corners of the outer flaps 17A, 17B, 18A, 18B.

  The folding assist fold lines 23A and 23B are outwardly directed from the portion P2 on the leading edge of the outer flaps 17A, 17B, 18A and 18B to the portion P4 on the second fold curve 19 beyond the sticking portions R1 and R2. It is provided to be curved and extend. The part P2 that is the starting point of the folding assist folding curves 23A and 23B is located on the center side of the gripping folding curves 21A and 21B, that is, inside the sticking portions R1 and R2. In the present embodiment, the portion P2 is set at the center of the front edge of the outer flaps 17A, 17B, 18A, and 18B by setting the width of the outer flaps 17A, 17B, 18A, and 18B. The part P4 that is the end point of the folding assist folding curves 23A, 23B is on the second folding curve 19 located on the extension line of the sticking portions R1, R2. The folding assisting folding lines 23A and 23B of the present embodiment have a parabola (1/4 ellipse) in which the distance from the sticking portions R1 and R2 gradually approaches from the front edge portion P2 of the outer flaps 17A, 17B, 18A, and 18B. ) It is provided to make a shape.

  In the blank of the packaging box 10, for example, the side wall 11B is bent with respect to the end wall 12B, and then the end wall 12A is bent with respect to the side wall 11A. And the margin part 13 superimposed on the outer surface side of the side wall 11B is fixed by a vinyl acetate emulsion system or hot melt.

  In use, for example, the lower inner flaps 16A and 16B are bent, and then the lower outer flaps 18A and 18B are bent and attached by hot melt on both sides of the lower outer flaps 18A and 18B. Thereafter, the upper inner flaps 15A and 15B are folded, and then the upper outer flaps 17A and 17B are folded and attached by hot melt on both sides of the upper outer flaps 17A and 17B. When the inner flaps 15A, 15B, 15A, 15B and the outer flaps 17A, 17B, 18A, 18B are attached by hot melt, the unfolding folding curves 23A, 23B of the present embodiment are formed of curved lines. It can be applied easily and reliably.

  When taking out the commodity stored in the packaging box 10, for example, the upper outer flaps 17A and 17B are peeled from the upper inner flaps 15A and 15B, and the upper end opening 20 is opened. For example, as shown in FIG. 2, one holding portion 22B of the upper outer flap 17A is bent along the holding folding curve 21B and raised outward. Thereafter, the gripping portion 22B is gripped and the upper outer flap 17A is pulled outward. Thereby, as shown in FIG. 3, the upper outer flap 17 </ b> A is bent along the folding assist folding curve 23 </ b> B.

  Here, the folding assist folding curve 23B is located on the opposite side of the gripping portion 22B with the sticking portion R2 interposed therebetween. Then, the folding assist folding curve 23B is used as a fulcrum by the valley fold, and the half region of the upper outer flap 17A acts away from the sticking portion R2 as in the so-called lever principle. As a result, the upper outer flap 17A can be peeled off from the sticking portion R2 with a small force. Moreover, as the peeling progresses, the distance from the gripping part 22B, which is the power point, to the peeling part of the sticking part R2, which is the action point, increases, but the opening assist folding line 23B has a tip edge part P2 with respect to the sticking part R2. Therefore, even if it is a part farthest from the grip portion 22B, it can be reliably peeled off with a small force.

  When the gripping portion R2 on the near side thus gripped is finished, the other sticking portion R1 can be subsequently peeled off. That is, when the grip portion 22B is subsequently pulled outward while being gripped, the second folding curve 19 that is the boundary line between the upper outer flap 17A and the end wall 12A is used as a fulcrum to move away from the sticking portion R1 on the far side. Directional force acts. As a result, as shown in FIG. 4, the sticking portion R <b> 1 can be reliably peeled off with a small force according to this principle. Of course, the other gripping part 22A may be gripped again and peeled off from the sticking part R1.

  Thereafter, the upper outer flap 17B is peeled off in the same manner to open the upper end opening 20 and take out the product inside.

  As described above, in the packaging box 10 to which the opening ruled line structure of the present embodiment is applied, the gripping portions 22A and 22B are positioned on the opposite side with respect to the gripping portions 22A and 22B with the sticking portions R1 and R2 interposed therebetween. The outer flaps 17A, 17B, 18A, and 18B can be peeled using the principle of the lever by using the folding assist folding lines 23A and 23B as fulcrums. Therefore, labor saving regarding the opening work can be achieved, and the opening workability can be reliably improved.
