[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is a paper container having a sheet cutting function capable of winding and storing a sheet of synthetic resin film, paper, or processed paper in a roll shape, and pulling out the end portion of the sheet to a predetermined length and cutting Regarding

[0002]

[Prior art]

 As is well known, synthetic resin films and aluminum foils used for packaging foods at home are stored in cardboard containers by winding them around a paper tube in a roll shape. Then, if necessary, the end of the film or aluminum foil is pulled out and cut with a cutting tooth provided on the front surface of the container or the tip side of the lid.

[0003]

[Problems to be solved by the device]

 By the way, the cutting teeth 2 provided in the conventional container 1 are made of metal, and have a chevron shape with a central portion 3 protruding to the bottom plate side 4 as shown in FIG. 8, and a film pulled out when cutting the film F. Is sandwiched between the flange 5 of the lid having the incisors 2 and the front plate 6 of the container 1, and then the container 1 is rotated downward to make an incision at the central portion 3 of the incisors 2 and pull the film as it is. The cut is expanded along the cutting teeth 2 in the width direction and cut. However, since the film F has a high tensile strength and elongation property, even if an attempt is made to cut the film F at the central portion 3 of the incisors during cutting, the film often stretches and the cut is not made well. Therefore, there is a drawback that the film F cannot be cut cleanly.

The present invention was made to eliminate the drawbacks of the above-mentioned conventional paper machine with incisors. The purpose of the present invention is to easily cut the stored items such as films and foils, and after cutting. The purpose of the present invention is to provide an incision paper container that does not wrinkle or get tangled in the film.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention integrally forms a main body composed of a bottom plate, a front plate, and a back plate with a single mount, and a lid for covering the opening of the main body, and a flange connected to the lid. In a container provided with sheet cutting incisors, the incisors are made of vulcanized fiber and have a shape projecting from both ends toward the center toward the bottom plate side, and in the center there are sharp conical teeth and both sides. It is characterized in that a protrusion formed of at least a pair of incision teeth having a tooth height lower than that of the conical teeth formed in the above is provided.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is an exploded view showing a paper container 10 having a sheet cutting function, and a box 11 made of paperboard and a cut piece integrally formed therewith. And teeth 12.

The box 11 is composed of a paperboard P as shown in the development view of FIG. That is, a rectangular bottom plate 13 is defined on the paperboard P, and front and rear plates 16 and 17 of the same shape are connected to the opposite long sides through folding lines 14 and 15, respectively. The adhesive pieces 20 and 21 are extended through the folding lines 18 and 19. On the other hand, on the opposite short sides of the bottom plate 13, a gable plate 23 with a flap 22 is continuously provided via a folding line 24. A lid 26 is connected to the long side of the back plate 17 via a folding line 25, and a flange 28 is connected to the lid 26 via a folding line 27. The flange 28 is divided into a cutting tooth holding piece 30 and an adhesive piece 31 by a break line 29 projecting from both ends toward the bottom plate 13 side.

Next, the cutting teeth 12 attached to the box body 11 will be described. The cutting teeth 12 are made of vulcanized fiber, and in this embodiment, have a thickness of about 0.5 mm and have a chevron shape projecting from both ends toward the center as shown in FIG. . The hypotenuse has the same inclination angle as the break line 29 provided on the flange 28 of the box body 12, and the edge of the hypotenuse is provided with serrated cutting teeth 12a having a blade height of 2 mm and a pitch of about 2 mm. At the same time, a protrusion 12b is formed on the top of the hypotenuse. As shown in the enlarged view of FIG. 3, the protruding portion 12b has a lower tooth height than the conical teeth 32 protruding in the central portion and the conical teeth 32 protruding on both sides thereof, and incision teeth 33, 3 having different heights. 4 and the length L of the protrusion 12b is at least 5 mm or more. In this embodiment, the apex angle θ of the intersection point P of the extension line connecting the vertices of the left and right incision teeth 33, 34 is an acute angle, but this angle may be an obtuse angle, and the incision teeth may be a pair of left and right teeth. But it's okay. The cutting teeth 12 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 water-resistant vulcanized fiber for the incisors and to coat the punched incisors with a size agent.

In assembling the container of the present invention having the above structure, first, the cutting teeth 12 are attached to the flange 28 of the lid 26. That is, as shown in FIG. 2, the cutting teeth 12a and the protruding portions 12b are projected from the breaking line 29 to the cutting tooth holding piece 30 which constitutes the flange 28, and are bonded and fixed using the hot melt adhesive H. Then, the front plate 16, the rear plate 17, and the end plate 23 are vertically raised with the bottom plate 13 as the center through the fold lines 18, 19, and 24, and the adhesive pieces 20 and 21 are positioned inside the end plate 23 to be adhered. Then, a rolled product G such as a synthetic resin film is stored in the box body 11, the opening surface is covered with the lid body 26, and the flange 28 is superposed on the front plate 16 to form the adhesive piece 31 constituting the flange. The adhesive H is spot-bonded to the front plate 16.

When opening the container 10 with the above-described configuration and taking out the product, first, as shown in FIG. 4, when the end portions of the adhesive pieces 31, 31 partitioned into the flange 28 are picked and pulled outward, the adhesive The piece 31 is torn along the breaking line 29, peeled from the front plate 16 and opened. Then, the end of the film wound into a roll is picked up to pull out a desired length, and after covering the object to be packaged, the base end of the film F is sandwiched between the incisor holding piece 30 and the front plate 16 to form a container. 10 is rotated downward (FIGS. 5 and 6). At the center of the cut surface of the film F pulled out by the rotation of the container, a hole is first bored by the conical tooth 32 of the protrusion 12b formed in the central part of the incisal tooth 12 (FIG. 7), and then both sides of the conical tooth 32 are cut. The holes are widened in the width direction by the cutting teeth 33 and 34 provided in, and the cutting surface is widened in the film width direction by the cutting teeth 12a to cut the film.

Since the container 10 of the present embodiment has the above-described structure, it is possible to surely form the cut hole at the center of the film F against the tensile strength and elongation of the film at the start of cutting the film F. The cutting work can be done reliably with a small force. In addition, the use of vulcanized fiber incisors, which have high elasticity and rigidity, does not cause tooth deformation or chipping due to external forces, and can be incinerated after use. Furthermore, the incisors of the container do not hurt your fingers.

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

[0013]

[Effect of the device]

 Since the present invention is configured as described above, it is possible to provide a container capable of safely and reliably cutting a film or foil with a small force. In addition, when used, not only the box but also the incisors can be incinerated at the same time, preventing the generation of dust pollution associated with non-combustible waste.
