In the drawings referred to below, the same reference numerals denote the same components. In addition, the dashed-dotted line in a figure shows a folding part. In the following description, the “left-right direction” is the width direction of the stored sheet, and refers to the up-down direction on the paper surface in FIG.

  The sheet packaging box according to the present invention will be described in detail with reference to FIGS.

  The sheet packaging box of the present invention includes a main body 100, a lid body 200, and a cutting blade 300, and a winding roll 400 of a sheet 401 is accommodated in the main body 100 to form a packaging body.

  As shown in FIG. 1, the sheet packaging box of the present invention can be formed by cutting out from one sheet material except for the cutting blade 300, bending it, and fixing a predetermined portion with an adhesive or the like. The sheet material used for the packaging box of the present invention is usually paper having elasticity and flexibility, and those having a surface appropriately coated with a resin layer are also preferably used. Further, the cutting blade 300 is separately formed from metal, resin, and paper, and is attached to a predetermined position of the lid 200.

  The sheet 401 stored in the sheet packaging box of the present invention is mainly food, cooking wrap film, aluminum foil, and cooking sheet. However, the use is not particularly limited as long as it is a similar sheet. These sheets 401 are provided in the form of a long sheet, wound around a cylindrical core material, or wound into a cylindrical shape without using a core material to form a wound roll 400, and the main body of the sheet package of the present invention 100.

  As shown in FIGS. 1 and 2, the main body 100 includes a bottom plate 10, a front plate 20 that is connected to each of the four sides of the bottom plate 10 via folding portions, and a side plate 30 a on the left and right (up and down direction in FIG. 1). , 30b and a back plate 40. Then, the front plate 20, the side plates 30a, 30b, and the back plate 40 are bent at 90 ° through the folding portions and raised from the bottom plate 10 to form the box-shaped main body 100. In the present embodiment, auxiliary pieces 21a and 21b are provided on the left and right sides of the front plate 20 via folding parts, and auxiliary pieces 41a and 41b are provided on the left and right sides of the back plate 40 via folding parts, respectively. Therefore, when the front plate 20, the side plates 30a and 30b, and the back plate 40 are respectively raised from the bottom plate 10, the auxiliary pieces 21a and 41a are respectively connected to the front plate 20 and the back plate 40 through the folding portions. The auxiliary pieces 21b and 41b are bent from the front plate 20 and the back plate 40 to the inner side of the side plate 30b by folding them at 90 ° through the folding portions, respectively. It can be stuck and fixed via an agent.

  In the present invention, the upper edge 22 of the front plate 20 is at the same position as or lower than the ends of the upper edges 32a, 32b of the side plates 30a, 30b on the front plate 20 side. In the embodiment shown in FIG. 4, the upper edge 22 of the front plate 20 is at a position lower than the end of the upper edges 32a and 32b of the side plates 30a and 30b on the front plate 20 side, The height H1 on the face plate 20 side is higher than the height H3 of the front plate 20 by h2.

  The lid 200 has an upper surface plate 50 connected to the upper edge of the back plate 40 of the main body 100 via a folding portion, and a suspension plate 60 connected to the front edge of the upper surface plate 50 via the folding portion. . Therefore, the upper plate 50 is bent from the rear plate 40 through the folding portion, and the suspension plate 60 is bent from the upper plate 50 through the folding portion and fixed by 90 °, thereby fixing the boundary between the suspension plate 60 and the upper plate 50. The lid body 200 in which the angle of the folded portion is fixed at 90 ° is formed. In the present embodiment, auxiliary pieces 51 a and 51 b are provided on the left and right sides of the upper surface plate 50 via folding parts, and auxiliary pieces 61 a and 61 b are provided on the left and right sides of the suspension plate 60, respectively. Therefore, the auxiliary pieces 51a and 51b are bent from the upper surface plate 50 to 90 ° via the folding portion, and similarly, the auxiliary pieces 61a and 61b are bent from the suspension plate 60 to 90 ° via the folding portion, and the auxiliary pieces 51a and 61a and 51b are bent. The lid body 200 can be easily formed by laminating and 61b.

  2 and 3, a cutting blade 300 for cutting the sheet 401 is attached to the lid 200, and the cutting blade 300 extends from the tip of the suspension plate 60 to the tip of the cutting blade 300. Is attached to the inside of the suspension plate 60 so as to protrude.

  In this embodiment, as shown in FIG. 1, an opening plate 70 connected to the suspension plate 60 via a perforation 80 is disposed at the tip of the suspension plate 60, and the opening plate 70 is used as a front plate of the main body 100. The lid body 200 is fixed to the main body 100 by being attached to the body 20 with an adhesive or the like. At this time, the tip of the cutting blade 300 attached to the inside of the suspension plate 60 is covered with the opening plate 70, and when opening, the lid 200 is opened by separating the opening plate 70 at the perforation 80 as shown in FIG. The tip of the cutting blade 300 is exposed and the sheet 401 can be cut.

  1 and 3, the upper edges 32a and 32b of the side plates 30a and 30b of the main body 100 are inclined downward from the back plate 40 side toward the front plate 20 side. There is. That is, the height H1 on the front plate 20 side is lower by h1 than the height H2 on the back plate 40 side of the side plates 30a, 30b.

  In the present invention, the upper edge 22 of the front plate 20 is located at the same position as or lower than the ends of the upper edges 32a and 32b of the side plate 30 on the front plate 20 side, and therefore is shown in FIG. Thus, when the sheet 401 is pulled out, the lid 200 is closed and the upper surface plate 50 is pressed so as to contact the upper edges 32a and 32b of the side surface plates 30a and 30b, the upper surface plate 50 also has the upper edges 32a and 32b. Is inclined from the back plate 40 side toward the front plate 20 side. The angle of the corners formed by the upper edges 32a, 32b of the side plates 30a, 30b and the end on the front plate 20 side is an obtuse angle exceeding 90 °, whereas the suspension plate 60 is folded from the top plate 50. It is bent at an angle of 90 ° through the part. Therefore, the suspension plate 60 in contact with the side plate 30a, 30b side edge on the front plate 20 side is more strongly pressed against the edge of the front plate 20 on the tip side than on the top plate 50 side.

  Furthermore, in the present invention, the width W2 of the top plate 50 is formed to be equal to the width W1 of the side plates 30a, 30b. Since the upper edges 32a and 32b of the side plates 30a and 30b are slightly longer than W1 and W2 due to the inclination, the upper plate 50 contacts the upper edges 32a and 32b and the lid 200 is closed. The upper surface plate 50 is pulled in the width direction, and the suspension plate 60 is strongly pressed against the edge of the front plate 20.

  Since the left and right sides of the suspension plate 60 are strongly pressed against the end sides of the side plates 30a and 30b, the entire suspension plate 60 is strongly pressed against the front plate 20 without a gap, and is attached to the inside of the front end edge of the suspension plate 60. The cutting blade 300 thus pressed is strongly pressed against the front plate 20 toward the inside of the main body 100. Therefore, when cutting the sheet 401, the front plate 20, the sheet 401, and the tip of the cutting blade 300 are in close contact with each other, and the sheet 401 can be cut well. In particular, the force that presses the tip of the cutting blade 300 against the front plate 20 is the strongest at the edge of the front plate 20 and has the highest adhesion at that position, so that the sheet 401 can be cut without being left uncut.

In the present invention, the degree of inclination of the side plates 30a, 30b, that is, the upper edges 32a, 32b with respect to the width W1 of the side plates 30a, 30b in the direction parallel to the folded portion where the side plates 30a, 30b and the bottom plate 10 are continuous . If the ratio (h1 / W1) of the height difference h1 between the front and the back is too small, sufficient force to press the tip of the cutting blade 300 against the sheet 401 cannot be obtained. It becomes difficult to contact the upper edges 32a and 32b of 30b, and conversely, it becomes difficult to cut the sheet 401. Although it depends on the value of W1 corresponding to the type of sheet 401, the material of the package, and the outer diameter of the wound roll 400 to be stored, h1 / W1 is preferably 0.022 to 0.067. For example, in the case of W1 = 45 mm in aluminum foil or wrap film packaging boxes that are widely sold, h1 is preferably about 1.0 to 3.0 mm.

  Further, in the present embodiment, the upper edges 32a and 32b of the side plates 30a and 30b are provided with auxiliary pieces 31a and 31b connected via a folding portion, so that the upper edges 32a and 32b are provided with the auxiliary pieces 31a. , 31b, the strength is improved as compared with the case without 31b.

  In the present invention, when the height H1 of the side plates 30a and 30b on the front plate 20 side is higher than the height H3 of the front plate 20 by h2, as shown in FIG. 20 does not come into contact with the upper edge 22, a gap of h2 is secured, and the sheet 401 can be pulled out without difficulty. The height of h2 is preferably about 1 to 3 mm.

  Further, as described above, in the present embodiment, by using the opening plate 70, the cutting blade 300 is not exposed until just before opening, and the opening body 70 can be easily opened by separating the opening plate 70. . Here, by making the total width H5 of the suspension plate 60 and the opening plate 70 equal to the width H4 of the back plate 40, when assembling the packaging box, the front end of the opening plate 70 is set to the lower end of the front plate 20. If attached together, even if the upper edges 32a and 32b of the side plates 30a and 30b are inclined, the upper surface plate 50 is not inclined forward and backward. Even if H5 and H4 are not equal, if H5 <H4, the top plate 50 is moved by shifting the tip of the opening plate 70 from the lower end of the front plate 20 when the opening plate 70 is attached to the front plate 20. Can be parallel to the bottom plate 10.

  Thus, the shape of the package can be a rectangular parallelepiped by assembling the top plate 50 so as to be parallel to the bottom plate 10. As a result, similar to the conventional package, there is no fear of slipping even when stacked in the vertical direction, and transportation and display can be performed as in the conventional case.

  In the sheet packaging box of the present invention, as described above, since the tip of the cutting blade 300 is closely attached to the front plate 20, the sheet 401 pulled out from the winding roll 400 is linearly formed from the start to the end at a desired position. It can cut well. Further, since the package is a rectangular parallelepiped, it can be handled in the same manner as a conventional package during transportation and display.
