DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case for storing a wrap film, which is widely used for packaging foods and the like, wherein the case is made of plastic and used permanently, and only used-up film rolls are replaced. Related to wrap film case.

[0002]

2. Description of the Related Art Conventionally, wrap films widely used at home are provided with a cutter inside one side of a rectangular paper box.
In general, a film roll is stored in a box, and the paper edge of the cutter section is broken, the film end is pulled out as a lid with a cutter, cut, and used.

[0003]

However, in this type of wrap case, the film roll may fly out of the box, or the roll may return after cutting and lose sight of the film end.
There is a lot of waste in taking this time and throwing it away.

[0004] In addition, the exposed portion of the cutter may cause injuries to the fingers, which is inconvenient in handling. In addition, even if a used paper box is treated, the metal cutter is used, and the combustible dust is harmful. And the trouble of having to separate each non-burnable garbage.

[0005]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to improve the inconvenience of using such a paper wrap case and the inconvenience of disposing of garbage after use. In the present invention, the wrap case A is permanently used only by replacing the disposable paper box with a plastic outer box and replacing the film roll.

The wrap case A can smoothly open and close the upper lid, take out the wrap film F and cut the film with one hand, do not rewind the wrap film F, and attach the magnet plate B to the back of the case A. By attaching it, it became possible to attach it to a metal plate such as a refrigerator.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing the entire wrap case A of the present invention, and FIG. . FIG. 3 is a cross-sectional view of FIG. 2XX, and FIGS. 4 and 5 are examples of main parts, respectively.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, (1) shows an upper lid of a wrap case A having an L-shaped cross section, and (2) shows a receiving box for accommodating a film roll F. The receiving box (2) has a U-shaped cross section as shown in FIG. 3 and is formed on a curved surface (3) so that one corner thereof receives the film roll F, and the base end of the upper lid (1) and the receiving box ( One end of 2) is joined by a leaf spring (4). A cutter (5) is provided at the tip of the L-shaped upper lid (1).

Then, a locking piece (6) is protruded from the center of the front end of the upper lid (1). Also, a spherical projection (7) is formed at the end of the curved surface (3) of the receiving box (2), and the locking piece (6) on the upper lid side and the spherical projection (7) on the receiving box side are connected to the upper lid (1). ) And the receiving box (2) are engaged with each other against the leaf spring (4) provided at the joint portion, so that the wrap case A is in the lid closed state, so that the wrap film F can be pulled out and cut.

This engagement is locked by the spherical projections (7), so that even if a film is inserted between the locking portions, the film can be easily pulled out and the film can be completely used up. As shown in FIG. 3, when the user replaces the cover, the finger can be pressed lightly on the side of the box as shown by arrow P to disengage the upper cover and open the upper cover (1) by the action of the leaf spring (4). A state is reached to facilitate removal of the film roll. (8) in the figure is a hole for inserting a finger, which makes it easier to take out a used roll.

Further, referring to FIG. 2, arc-shaped protrusions (9) are provided at both longitudinal ends of the receiving box (2) to prevent the film roll from jumping out. 9-1)
And is fitted in an arc shape to the core of a film roll (a cardboard cylinder) to facilitate pushing and pulling of the roll.

Also, a magnet plate B can be provided on the back of the receiving box (2), which can be attached to a metal plate such as a refrigerator, so that the wrap film can be easily taken out even during cooking.

[0013]

As described above, the present invention has been described. The wrap case of the present invention is made of plastic, so that the opening and closing of the upper lid, the taking out of the wrap film and the cutting of the film can be smoothly performed with one hand, and also the winding of the film roll. There is no return, and the magnet plate B is provided on the back side so that it can be attached to the side of the refrigerator etc. so that it can be conveniently used even during cooking because it can be used conveniently. In comparison with the above, the present invention has an excellent operational effect in that refuse disposal can be performed very easily.
