【Example】

 The present invention will be described in detail with reference to the illustrated embodiments. FIG. 1 is a perspective view showing a first embodiment of the present invention, and FIG. 2 is an exploded view showing a carton with a cutting tooth 1 in the drawing, which comprises a box body 2 made of paperboard and a cutting tooth 3 attached thereto. Composed.

The box body 2 is composed of a paperboard P as shown in the development view of FIG. That is, a rectangular bottom plate 4 is defined on the paper board P, and front and rear plates 7 and 8 of the same shape are connected to the opposite long sides through folding lines 5 and 6, respectively. Adhesive pieces 11 and 12 are extended through fold lines 9 and 10. On the other hand, end plates 14 are connected to each other via fold lines 15 on opposite short sides of the bottom plate 4. A lid 17 is connected to the long side of the back plate 8 via a fold line 16, and a joint piece 19 is connected to the lid 17 via a fold line 18. The joining piece 19 is divided into a cutting tooth holding piece 21 and an adhesive piece 22 by a V-shaped breaking line 20 inclined from both ends toward the center. In FIG. 2, reference numerals 23 and 24 are flaps for adhesion provided on the lid body 17 and the incisal tooth holding piece 21, and 25 is a folded piece continuous with the front plate 7.

Next, the cutting teeth 3 attached to the box body 2 will be described. The incisor 3 is made of vulcanized fiber, and in this embodiment, it has a thickness of about 0.35 mm, a width of about 8 mm, and a length slightly shorter than the long side of the bottom plate 4. It is inclined toward the part and has a V shape. The inclination angle is the same as the V-shaped breaking line 20 provided on the joining piece 19 that is connected to the lid body 17 of the box body 2, and is about 2 degrees in this embodiment. Further, a sawtooth-shaped common tooth 3a and a conical tooth 3b having a blade height higher than that of the common tooth 3a are formed on the inclined surface (FIG. 3). In this embodiment, the common teeth 3a have an apex angle of 60 degrees, a blade height of 1,4 mm and a pitch of 1,6 mm, and the conical teeth 3b have an apex angle of 50 degrees, a blade height of 2,2 mm and a pitch of 2 mm. One is provided at the center of the incisor 3 and two are provided at both ends of the common tooth 3a at a pitch of 5 peaks. The cutting teeth 3 can be easily obtained by punching a plate made of vulcanized fiber with a press or the like. Since vulcanized fiber is inferior in water resistance, it is preferable to use vulcanized fiber that is water-resistant and moisture-proof for cutting teeth, or to coat punched cutting teeth with a size agent or the like. In this embodiment, since the base material is continuously punched out to form the cutting teeth 3, an uneven surface opposite to the tooth top is formed on the end surface opposite to the tooth top.

In assembling the carton of this embodiment having the above-described structure, first, the cutting teeth 3 are attached to the cutting-tooth holding piece 21 that constitutes the joining piece 19. That is, it is attached using the hot melt adhesive H in a state in which the tips of the cutting teeth 3 project when the adhesive piece 22 is broken from the breaking line 20 portion. Then, the front plate 7, the rear plate 8 and the end plate 14 are vertically raised by the fold lines 5, 6 and 15 with the bottom plate 4 as the center, and the adhesive pieces 11 and 12 are positioned inside the end plate 14 to be adhered and folded. The piece 25 is folded inside the front plate 7. Next, the rolled product F such as a synthetic resin film is housed in a carton, and the adhesive flap 24 provided on the joining piece 19 is adhered to the inside of the flap 23 of the lid body 17 to cover the opening surface and join. The piece 19 is superposed on the front plate 7, and the adhesive piece 22 divided into the joining pieces 19 is adhered to the front plate 7 with the adhesive H.

When opening the carton with the vulcanized fiber tooth having the above-mentioned structure and taking out the product, first, as shown in FIG. 4, when the end of the adhesive piece 22 divided into the joining piece 19 is picked and pulled outward, 22 is torn along the breaking line 20 and peeled off from the front plate 7 to be opened. Then, the end of the film wound into a roll is picked up to pull out a desired length, and the film is hung down from the upper edge of the front plate 7 along the front plate 7. Then, the opening is covered with the lid 17 and the film F Is clamped by the front plate 17 and the incisor holding piece 21. Next, as shown in FIG. 5, the film F that has been pulled out is placed on the object to be packaged G, and the central portion of the incisor holding piece 21 is pressed by the thumb of the hand holding the carton 1, and the hand holding the film F and the carton 1 By pulling the holding hand in the separating direction, cut with the incisors 3. That is, when the cut portion of the film F is brought into contact with the cutting tooth 3 at a right angle and pulled in the separating direction, first, the cutting tooth 3 is V-shaped and both ends thereof protrude, and the cutting edge 3 has a blade height higher than that of the common tooth 3a. Since the high conical tooth 3b is projected, a hole is made in the film F by the conical tooth 3b, and the hole is expanded by the common tooth 3a in the width direction of the film by pulling the hole. It is to cut. The opening is closed with the lid 17 after use.

Since the carton of this embodiment has the above-described structure, it is not necessary to rotate the carton and the film up and down as in the conventional case when cutting the film, and the film can be cut by simply pulling it to the left and right. It is possible to prevent wrinkles and overlap of the film edges that occur during rotation.

In the above embodiment, the incisor 3 is composed of the common tooth 3a and the conical tooth 3b having a higher blade height, and the conical tooth 3b is arranged at the center and both ends, but the invention is not limited to this. For example, the arrangement as shown in FIG. 6 may be used instead.

Further, it is needless to say that the present invention is not limited to the above-described embodiment, and various modifications and design changes can be made without departing from the spirit of the invention.
