A sheet take-out port 24 for taking out the sheet is formed so as to straddle the cover lid piece 22 through the sewing machine hole. Sheet cutting teeth 26 are formed on the upper edge of the front plate 23 facing the sheet outlet 24. The cooking paper wound on the winding core is housed in the box. As shown in FIG. 7C, the roll sheet 27 is pulled out from the opened sheet take-out port 24 to the outside of the storage box by a required length, and the pulled sheet 27 is cut at the upper edge portion of the front plate. Cut with teeth 26.

[0004]

However, in the prior art example shown in FIG. 7, when the pulled-out sheet 27 is cut by the tooth portion 26 formed at the upper edge of the front plate, the cutting point of the sheet is cut. However, the strength of the front plate is weak and the front plate 23 itself tends to bend inward or outward due to the force of the pressed sheet. Further, since the tooth portion 26 is composed of one front plate, it is easily bent by the force of the sheet pressed by the tooth portion itself. Therefore, when a sheet that is easily stretched or has high strength is pulled out and cut, the tooth cutting function is inferior and the sheet is difficult to cut.

The present invention has been made in view of the above-mentioned problems of the conventional type.
A roll sheet in which the opening lid of the sheet take-out port is folded back to make it a truss structure to have strength, and teeth are projected at the edge of the take-out port to facilitate cutting of the roll sheet. The purpose is to provide a storage box.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a development view of a storage box with a roll sheet cutting function of the present invention, and FIGS. 2 to 4 are perspective views showing a usage state of the storage box. Note that FIG. 3 and FIG.
Shows the state in which the roll sheet is omitted so that the structure of the box can be easily understood.

In FIG. 1, a rectangular back plate 1, a top plate 2,
The front plate 3 and the bottom plate 4 are continuously provided in one direction via folding lines a to c along the long side. Each of these plates 1 to 4 has the same size, and a joining piece 5 is attached on an extension of one long side d of the bottom plate 4. Further, inner and outer flaps 6 to 9 serving as side lids are attached to both left and right short sides of each plate through folding lines e and f. These are formed by using paperboard as an example.

On the top plate 2, a hinge portion 12 is formed so as to be openable and closable so as to be parallel to the long side. A plurality of tooth portions 16 are formed on the hinge portion 12 by a chevron notch so as to project into the outlet 11 intermittently or continuously. Further, cutout perforation lines 13 are formed so as to reach the central portion of the front plate 3 from both ends of the hinge portion 12 beyond the folding line b. This cut out perforation line 1
3, a sheet take-out port 11 is formed which extends over the top plate 2 and the front plate 3 so that the roll sheet can be taken out. Inside the cut-out perforation line 13, there is a hinge 1
A lid plate 11 a that closes the sheet outlet 11 is connected to the top plate through the line 2. Then, a cut-out knob / insertion holding piece 11b is formed on the front end side of the lid plate 11a through a fold line g. A slit 14 is formed in the rear of the hinge portion 12 provided on the top plate 2 in parallel with the hinge portion.

In order to assemble the box constructed as described above from the unfolded state, the back plate 1, the top plate 2, the front plate 3 and the bottom plate 4 are connected to each other through the joining piece 5 in a rectangular tube shape, and then, A roll sheet 20 such as a cooking paper or a paper towel wound in a roll shape is put in the inside of the rectangular tubular body, and both end openings of the tubular body are closed by inner flaps 6 and 8 according to a standard method, and outer flaps 7 and 9 are superposed on the outside thereof. And adhere to obtain an assembled box as shown in FIG.

In use, the roll sheet 20 is fed from the inside of the box.
In order to take out the sheet, the cut-out knob / insertion holding piece 11b is first sandwiched by the thumb and forefinger, and the sheet take-out port 11 at the center of the front plate 3 and the top plate 2 is opened along the sewing machine 13 (see FIG. 3). .

Next, the lid plate 11a is pinched and turned backward via the hinge portion 12. Then, the cut-out knob and insertion holding piece 11b on the tip side of the lid plate is inserted into the slit 14 at the rear of the hinge portion 12 and fixed on the top plate 2,
The lid plate 11a is bent into a triangular shape so as to have a truss structure and then held (see FIGS. 4 and 5).

At this time, as shown in FIG. 5, the hinge portion 12 is formed so that a plurality of chevron-shaped tooth portions are projected into the outlet 11 intermittently or continuously. After the roll sheet 20 is pulled out from the inside of the box by a desired length with a finger, the cut portion of the sheet is pressed against the tooth portion 16 to cut the sheet.

In this case, since the lid plate 11a has a truss structure of high strength, which is bent and fixed on the top plate so that the cross section has a triangular shape, the lid plate 11a is pressed by the force of the pressed sheet.
The corners are not crushed, and the teeth provided on the hinge are not warped or bent. Since the tooth portion is formed at the apex of the V-shape where the top plate and the lid plate intersect at an acute angle, the tooth portion can easily cut the sheet (see FIG. 5).

The tooth portion may be hardened with a resin, or a cutting member may be separately attached to the tooth portion.
