As shown in FIG. 3, in the state before the case is opened, the back surface of the opening piece 17 and the front surface of the front side plate 18 of the case body 11 are bonded by the glue 19 at several spots. A wrap film W wrapped around a cylindrical core 22 is housed in the case body 11. The wrap film W is, for example, a vinylidene chloride-based, vinyl chloride-based, or butadiene-based synthetic resin film.

A metal cutting member 21 is attached to the back surface of the edge of the cover lid piece 15. A saw blade 21a is formed at the tip of the cutting member 21.
Protrudes from the edge of the covering piece 15, and the saw blade 21a is located on the back side of the unsealing piece 17 in the state shown in FIGS. The cutting member 21 has a projecting shape in which the central portion C approaches the bottom side 11 a of the case body 11. That is,
In the embodiment shown in FIGS. 1 and 2, the central portion C of the cutting member 21 is an edge, and the cutting members located on both sides of this edge extend in a straight line while being inclined with respect to the bottom side 11a of the case body 11. Has become. Corresponding to this, the perforation 16 serving as the boundary between the covering lid piece 15 and the unsealing piece 17 is also formed in a protruding shape, and the covering lid piece 15 has a substantially triangular shape.

Further, as shown in an enlarged manner in FIG. 5, the front side plate 18 of the case body 11 has its upper edge bent to the inside of the case, and the bent piece 18a and the back surface of the front side plate 18 are separated from each other. It is adhered by the adhesive tape 23. As shown in FIG. 2, a cutout 18b is formed in the front side plate 18, and the adhesive tape 23 is exposed in the cutout 18b. The adhesive tape 23 exposed from the notch 18b allows the front side plate 18 to remove the wrap film W that is pulled out from the inside of the case body 11 and remains after being cut.
Function to hold in position. Furthermore, the cover piece 1
The U-shaped notch 15a is made in 5 and the portion sandwiched by the notch 15a is the pressing piece 1.
It is 5b. As shown by the chain line in FIG. 5, the pressing piece 15b can be deformed inward of the covering piece 15. When the pressing piece 15b is pressed by a finger when the wrap film W is cut by the cutting member 21, the pressing piece 15b is deformed inward, and the wrap film W pulled out in front of the front side plate 18 is inside the notch 18b. Although it is pressed against the adhesive tape 23, the rectangular coordinates XYZ are superposed on the storage case as shown in FIGS. 1, 2, 6, and 7 for convenience of explanation of the usage. The X axis is an axis perpendicular to the surfaces of the back plate 13 and the front plate 18,
The direction from the back side plate 13 to the front side plate 18 is (+), and the direction from the front side plate 18 to the back side plate 13 is (-). The Y-axis is the axis perpendicular to the surfaces of the side plates 28 and 29, and

The Z axis is an axis perpendicular to both the X axis and the Y axis, and the direction from the bottom side 11a to the opening 12 is (+), and the direction from the opening 12 to the bottom side 11a is (-).
Is.

A method of using the storage case for the wrap film W according to the above-mentioned embodiment after the XYZ axes are superposed in this manner will be described. When opening the case, the opening piece 17 adhered to the front side plate 18 of the case body 11 is peeled off and separated from the covering piece 15 along the perforations 16.
When the unsealing piece 17 is removed, as shown in FIG.
The saw blade 21a of the cutting member 21 is exposed from the edge portion of No. 5. After removing the unsealing piece 17, the upper edge H of the back plate 13 of the case body 11 serves as a hinge, and the lid 14 and the covering piece 15 can be opened and closed with respect to the opening 12 of the case body 11.

After opening the case, the wrap film W wound around the core 22 is pulled out from between the front side plate 18 and the covering piece 15. After pulling out the wrap film W for the required length,
For example, as shown in FIG. 6, the storage case is held by the left hand, and the covering lid piece 15 is pressed by the thumb. Alternatively, the lid 14 is pressed with the thumb. Further, the wrap film W grasps the central portion of the tip portion thereof with the right hand. Since the saw blade 21a of the cutting member 21 protruding from the edge of the covering lid piece 15 has a projecting shape whose center portion C is an edge, when the center portion of the wrap film W is pulled in the + X direction by the right hand, the saw blade 21a The central portion of the wrap film W is cut by the edge of the central portion C of 21a. When the wrap film W is pulled as it is, the notches progress along the saw blades 21a toward both edges of the film, and the wrap film W is cut cleanly. As described above, since the wrap film W can be cut by simply pulling it in the + X direction with respect to the storage case, wrinkles do not occur on the wrap film W after cutting, or the films do not adhere to each other in a twisted state. Therefore, if you cut down the wrap film W after cutting with your right hand as it is toward the object to be packaged such as food and trays, the wrap film W will have a sufficient area in a substantially horizontal (XY plane) state. And is installed on the article to be packaged. The above is the method of using the storage case of the present invention.

Further, when the wrap film W is cut in the state of FIG. 6, if the pressing piece 15b formed by the notch 15a of the covering lid piece 15 is pressed with the thumb of the left hand, the pressing piece 15b is pushed to the back side thereof. The positioned wrap film W can be pressed into the inside of the notch 18b formed in the front side plate 18 of the case body 11. Therefore, the wrap film W left between the covering lid piece 15 and the front plate 18 after the cutting is completed is held by the adhesive tape 23 in the notch 18b, and the wrap film W is completed after the packaging is completed. It is prevented from being rewound inside.

In the second embodiment shown in FIG. 7, the covering lid piece 15 and the cutting member 21 attached to the covering lid piece 15 are made to project in a substantially trapezoidal shape at the center thereof. In this case, the method of cutting the wrap film W is the same as that of the embodiment shown in FIG. 6, and the saw blade 21a located at the trapezoidal projection J is simply pulled by pulling the central portion of the film in the horizontal direction. Thus, the wrap film W is cut from the central portion and cut cleanly. Further, in this second embodiment, if the front side plate 18 of the case body 11 is provided with a substantially arcuate cutout 18c, after the wrap film W is cut by a required length, the protrusion J is formed in the cutout 18c. Will be able to plug in. With this, the lid 14 when not in use
Can be prevented from opening.

In each of the illustrated embodiments, the cutting member 2 is used.
1 has a shape that is deformed at an acute angle such as a substantially triangular shape or a trapezoidal shape, but the cutting member 21 may be formed in an arc shape so that the central portion projects. Further, the edge of the central portion C shown in the embodiment of FIG. 2 or the protruding portion J in the embodiment of FIG. 7 does not necessarily have to be provided at the center of the cutting member 21, and may be provided in any of the longitudinal directions of the case. It may be provided in a biased position.
