DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transparent resin sheet which can be put on a box containing grapes, cherries and the like in a state where the contents can be seen. A removable adhesive sheet that can be removed, stored in a box again, covered with the same sheet, and adhered.

[0002]

2. Description of the Related Art Grapes and cherries, which are stored items, do not rot at once, and decay proceeds in units of grains. Conventionally, when putting in and out, the bottom part of the box is opened and closed, and a thick plastic plate with a certain degree of stiffness is bent in a U-shape and covered with cellophane tape on both sides. Was.

[0003]

When opening and closing the bottom of the box, it is necessary to have a special box structure. When the contents are taken in and out, the stored items are easily damaged because the top and bottom are turned upside down, The fruit juice was attached to the box and the appearance became worse. If the box was lifted without the bottom, the bottom could fall off and the strength was weak. In the method of bending in the shape of “U”, it is necessary to have a moderate waist, so it is necessary to increase the thickness, which requires more material, increases the cost, increases the amount of garbage, and adds extra tape It took time and effort.

[0004]

Means for Solving the Problems The box for storing is made of corrugated cardboard, so that it can be peeled off after the sheet is adhered by using a method that can be peeled off and adhered again. Then, the paper was peeled off and stuck to the sheet, and it was not possible to repeat sticking and peeling. Therefore, by providing a protective film made of resin between the sheet and the paper box, the protective film protects the surface of the box from peeling, so that the sheet can be repeatedly attached and peeled, and opening and closing of the box bottom becomes unnecessary.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view partially showing the right side of the product of the present invention. The second adhesive layer 2 is provided leaving an appropriate deduction band to the outside, and appropriately protrudes to the lower surface via the second adhesive layer 2 from the outer edge of the second adhesive layer 2 to the outside. Protective film 3 is provided at a position that is appropriately inward from the outer edge, and sheet 1
A region not having the second adhesive layer 2 at the side end is provided as a second handle region 4, and the outer edge of the upper surface of the protective film 3 does not have the second adhesive layer 2. A deduction area band having no deduction area is provided as a deduction area 8, the second adhesive layer 2 uses a double-sided adhesive tape, and a surface adjacent to the sheet 1 is strongly bonded (hereinafter, referred to as a strong adhesion). Is weakly adhered (hereinafter referred to as "weakly adhered"), the first adhesive layer 5 is provided with the inner and outer edges on the lower surface of the protective film 3 aligned, and the inner surface is moderately attached to the lower surface via the first adhesive layer 5. The release paper is provided in such a state that the outer edge is aligned with the outer edge of the sheet 1, and the material of the release paper is made of opaque paper and is coated so as not to adhere.
In the case where a region band having no first adhesive layer 5 inside the release paper 6 is provided as a first handle region 7, the first adhesive layer 5 is also made of a double-sided adhesive tape, and both sides are strongly adhered and used. If the first handle area 7 on the inside is picked and peeled outside, the second adhesive layer 2
Since the inner edges of the protective film 3 and the first adhesive layer 5 are aligned vertically, only the release paper 6 is peeled off.

In FIG. 2 which is a partial front view of the right side showing an example of use of the present invention, after the release paper 6 of FIG.
The first adhesive layer 5 is adhered to the upper part of the side surface, and the sheet 1 is adhered and fixed to the outer layer via the protective film 3 and the second adhesive layer 2.

In FIG. 3, which is a partial front view of the right side showing an example of use of the present invention, the sheet 1 is peeled from the protective film 3 by unraveling the second handle area 4 and pulling it upward. From the front and back surfaces of the second adhesive layer 2, the protective film 3 on the back surface is weakly bonded, and the sheet 1 on the front surface is strongly bonded. The protective film 3 is left adhered to the box 9 because both the front and back surfaces of the first adhesive layer 5 are strongly adhered to each other, and the box 9 made of corrugated paper is provided by the presence of the protective film 3. Is protected, the sheet 1 can be repeatedly attached and detached, and the presence of the deduction area 8 makes it easier for the second adhesive layer to be detached from the protective film 3.

In FIG. 4, which is a perspective view showing a state in which the sheet of the present invention is covered, both ends of the sheet 1 are adhered to the upper side of the box 9, the shape of the box 9 is a rectangular parallelepiped, and the thickness of the peripheral wall is thick. The wall is provided with a structure called a picture frame, and the seat 1 is provided with a plurality of air holes 10 for gas exchange.

In FIG. 5, which is a cross-sectional view taken along the line AA in FIG. 4, the upper portion of both sides of the box 9 is provided via the first adhesive layer 5, the protective film 3, and the second adhesive layer 2. Both ends of the sheet 1 are adhesively fixed, and the second handle area 4 at both ends of the sheet 1 is provided.
By picking and pulling it up, the end of the sheet 1 can be peeled off and opened, and only rotten particles such as grapes and cherries, which are stored items, can be picked up and stored again and sealed.

[0010]

The present invention can be opened and closed by sticking the sheet to be sealed on the top, so that it can be applied to any open box on the top, and the strength is strongly maintained because the bottom is not opened and closed. Since both sides of the sheet are adhered and fixed, there is no need to use a stiff sheet, and it is not necessary to stop using a cellophane tape.
