Japanese Utility Model Publication No. 56-49723

  However, the packaging box is intended to improve the convenience of packaging work and shape retention in the packaging state, and for example, it has not been possible to obtain a sales promotion effect in a business negotiation.

  Then, this invention makes it a subject to provide the packaging box excellent in appealing property which can give a strong impression at the time of opening.

  In order to solve the above-mentioned problems, the present invention is provided with a lid that is openably and closably connected to the upper end of the peripheral wall, and the flaps extending from both sides of the lid and the upper end of the peripheral wall via a triangular connecting piece. In the packaging box in which the boundary with the diagonal fold line, interlocking the opening and closing of the lid and the flap, put the middle fold line in the flap, form a hook portion at the tip of the flap, provide a guide piece that engages the hook portion, When the lid was opened, the hook part was slid along the edge of the guide piece, and the flap was bent in a mountain shape along the middle fold line so that it was raised.

  In the packaging box according to the present invention, when the lid is opened as it is opened, the flap gradually rises and becomes three-dimensional in conjunction with the lid. It can be attracted and high appeal can be obtained.

  First, a first embodiment of the present invention will be described with reference to FIGS.

  This packaging box is formed from a cardboard blank as shown in FIG. In this blank, as a constituent member of the peripheral wall 16, the side wall 2, the rear wall 3 and the side wall 2 are sequentially connected to one side of the front wall 1, and the passage piece 4 is continuously connected to the other side of the front wall 1. Yes. A bottom plate 5 is connected to the lower ends of the front wall 1 and the rear wall 3, a bottom plate 6 is connected to the lower end of the side wall 2, a lid 7 is connected to the upper end of the rear wall 3, and a flap 8 is connected to the upper ends of the pair of side walls 2. However, a guide piece 9 is connected to the upper end of the front wall 1.

  Both sides of the lid 7 and the flap 8 are connected via a triangular connecting piece 10, and the boundary between the flap 8 and the connecting piece 10 is 45 ° that bisects the right angle formed by the side wall 2 and the lid 7. A diagonal line 11 is entered. The oblique line 11 is a lead rule where the crease and cut are intermittent.

  The flap 8 is provided with a middle folding line 12 in the width direction at an intermediate portion, and the middle folding line 12 is also a lead rule in which a crease and a cut are intermittent. A hook portion 13 that curves outward is formed at the distal end portion of the flap 8, and a stopper portion 9 a that contacts the hook portion 13 and restricts the opening degree of the lid 7 is formed on both sides of the distal end edge of the guide piece 9. Has been.

  An insertion piece 14 is provided at the center of the distal end of the lid 7, and a slit-like insertion hole 15 is provided along the ridge line with the front wall 1 at the center of the base end of the guide piece 9.

  In order to assemble such a blank and wrap a product, as shown in FIG. 2, the front wall 1, the pair of side walls 2 and the rear wall 3 are bent into a rectangular tube shape, and the passage piece 4 is attached to the other side wall 2. The peripheral wall 16 is formed by pasting, the bottom plates 5 and 6 are bonded together one by one, and the bottom plates 5 are closed by engaging the opposing bottom plates 5 with each other.

  Next, the product is stored in the box, the guide piece 9 is folded inwardly in the horizontal direction, the oblique fold line 11 is folded in the valley, the connecting piece 10 is folded, the flap 8 and the lid 7 are closed, and the hook portion 13 is guided. The insertion piece 14 is inserted into the insertion hole 15 and sealed so as to be engaged with the guide piece 9 so as to be pushed downward of the piece 9.

  On the other hand, when the manufacturer's sales representative explains the product packaged in this way in order to obtain a handling contract with a distributor in the distribution industry, as shown in FIG. The piece 14 is pulled out from the insertion hole 15, and the lid 7 is opened so that the product can be seen.

  Along with this, the base end side of the folding line 8 of the flap 8 is pulled up to the connecting piece 10 and the hook portion 13 is slid along the edge of the guide piece 9 while the flap 8 is bent in a mountain shape along the folding line 12. It gets excited.

  For this reason, in the packaging box described above, if the flap 8 is printed to enhance the image of the product, the flap 8 that is three-dimensionally opened can attract the purchaser's interest and strengthen the impression. A promotion effect can be expected.

  Next, a second embodiment of the present invention will be described with reference to FIGS. Here, only parts different from the first embodiment will be described.

  The packaging box is made of paperboard, and the blank is composed of an outer lid plate 7a and an inner lid plate 7b in which the lid 7 is sequentially connected from the rear wall 3, as shown in FIG. Further, the middle folding line 12 is inserted in a V shape so that the outer end of the base portion of the connecting piece 10 is a valley, and an arcuate edge 9b is formed at the center of the end edge of the guide piece 9 by cutting.

  When assembling this blank, as shown in FIG. 5, the outer lid plate 7 a and the inner lid plate 7 b are bonded together to form the lid 7.

  Then, when the lid 7 is opened, the flap 8 rises up with a triangular top surface, and the gap between the openings between the opposing flaps 8 increases toward the rear, The opening at the time of change can strengthen the impression at the time of opening.

  Next, a third embodiment of the present invention will be described with reference to FIGS. In this case, only the parts different from the first and second embodiments will be mentioned.

  This packaging box is made of a paperboard blank shown in FIG. 6, and as shown in FIG. 7, in the assembled state, the peripheral wall 16 forms a hexagonal cylinder, and the side wall 2 has an obtuse angle on both sides. It is connected to. The bottom surface is closed by a single hexagonal bottom plate 5, and the bottom plate 5 and the side wall 2 are fixed by pasting the respective passage pieces 5a, 2a to the other party. The outer lid plate 7 a and the inner lid plate 7 b are also hexagonal, the guide piece 9 is also beveled on both sides, and the passage piece 9 c is attached to the side wall 2.

  In such a packaging box, not only the packaging state but also the impression at the time of opening can be strengthened by the characteristic shape of the hexagonal column and the flap 8 that is three-dimensionalized while opening, and a sales promotion effect can be expected. .

  In each of the above embodiments, the lid 7 is illustrated as being continuously provided only at the upper end of the rear wall 3. However, the lid 7 is continuously provided at the upper ends of the front wall 1 and the rear wall 3 so as to be open. Thus, a guide piece 9 may be provided in a partition between the inner surfaces of the opposing side walls 2, and the hook portion 13 of the flap 8 may slide along the guide piece 9.

The figure which shows the blank of the packaging box which concerns on 1st Embodiment of this invention The perspective view which shows a packaging state same as the above The perspective view which shows an open state same as the above The figure which shows the blank of the packaging box which concerns on 2nd Embodiment of this invention The perspective view which shows an open state same as the above The figure which shows the blank of the packaging box which concerns on 3rd Embodiment of this invention The perspective view which shows an open state same as the above
