In addition, perforations M and M are provided on both side panels 12 and 14 obliquely in succession to the notch j on the upper side of the zipper J. Further, the rear panel 13 is provided with a broken line i that is continuous with the perforations M, M. Therefore, by lifting the knob T, tearing the zipper J of the front panel 11, and tearing the perforations M, M of the side panels 12, 14, a lid that can be opened and closed with the broken line i as a hinge can be formed.
[0017]
In addition, the bottom panel 14 and the glue margin panel 15 are formed in a portion wider than the end side at a portion that overlaps with the end side of the knob portion T of the zipper J of the front panel 11 when assembled in a carton at a substantially central portion of the broken line d. The fold line d14 and the fold line d15 are provided in an arcuate shape on the bottom panel 14 side and the glue margin panel 15 side so as to form a recess O when bent at a right angle along the fold line d. That is, the polygonal line d14 and the polygonal line d15 have a convex lens shape.
[0018]
Further, in the portion adjacent to both sides of the zipper J on the edge of the front panel 11, as shown in the partial enlarged view of FIG. 5, cut according to the shape of the broken line d 15 of the glue margin panel 15 for forming the recess O. It is good also as a shape which provided the chip | tip P. By adopting this shape, the knob portion T is more easily picked and is preferable in appearance.
[0019]
In the second embodiment as well, the width of the recess O with respect to the knob T of the zipper J is set wider than the width of the knob T in the present embodiment. If it becomes easy to pick, it is good also as the same width or a narrow width.
[0020]
Moreover, the shape of the recessed part O should just form a recessed part so that the knob | pick part T of the zipper J may be easily picked in the ridgeline which the edge of the zipper J overlaps, and other than the convex lens shape shown in the present Example, As in the case of the embodiment, various shapes can be used.
[0021]
FIG. 6 is a perspective view of an example of a third embodiment of a carton with a zipper according to the present invention. In the carton C with a zipper according to the present invention, a zipper J- is provided on the top of the top panel 16. And the front-end | tip part forms the picking part T by putting the cut lines t and t from the front-end | tip. Further, a concave portion O is formed on the ridge line of the carton where the ends of the knob portion T overlap to form a wide gap between the knob portion T and the carton.
[0022]
FIG. 7 is a developed view of the blank of the carton C with zipper of FIG. In the blank C1, the front panel 11, the side panel 12, the rear panel 13, the side panel 14, and the adhesive margin piece 15 are continuously provided via the broken lines a, b, c, and d. The top panel 16 is connected to the upper side of the front panel 2 via a broken line e, the bottom panel 17 is connected to the lower side of the front panel 2 via a bent line e, and the folded pieces 18 are connected to the upper and lower sides of the side panel 12. 19 is connected to the upper side of the rear panel 13 via a broken line g, and the bottom panel 21 is connected to the lower side of the rear panel 13 via a broken line g.
