Description

[Detailed Description of the Invention] The present invention relates to a simple box for storing trash and other items.

Hereinafter, the present invention will be described in detail based on specific embodiments shown in the accompanying drawings.

The present applicant is Utility Application No. 58-88357
No. 13935) has already been filed as a ``simple box,'' and the present invention relates to its improvement. The first point is that when opening the folded simple box, the free folded piece that is not attached firmly contacts the inner wall of the upper opening of the square-bottomed bag from the inside, and the outside of the wall of the upper opening of the square-bottomed bag. When the simple box is opened, the movement of the lower end of the side of the folded piece to the outer position is delayed than the movement of the upper edge of the wall of the upper opening of the square bottom bag to the outer position. The fold line is attached so as to be located slightly above the upper edge of the square bottom bag, so that the simple box can be reliably and easily opened into a square shape. The second feature is that a protrusion is provided on the side of the folded piece in order to maintain the squarely opened state, and an engagement hole is provided at the position of the square bottom bag corresponding to the protrusion.

Folded pieces 3 and 4 are formed around the four sides of a square paperboard top cover 2 in which a hole 1 is bored. One opposing bent piece 3 is formed so as to come into contact with the inner wall of the upper opening of the square-bottomed bag 5 that can stand on its own, and the other opposing bent piece 4 is formed on the outer wall surface of the upper opening of the square-bottomed bag 5. The folded piece 4 is pasted so that the fold line 6 is located slightly above the upper edge of the wall surface of the square bottom bag 5 by about 5 to 10 mm. A fold line 7 is carved from the center of one of the opposing folded pieces 3 to reach the hole 1. Projections 8 are provided to protrude outward from the lower ends on both sides of the bent piece 3, and engagement holes 9 are bored at positions of the square bottom bag 5 (upper corners of the wall surface) corresponding to the projections 8. Reference numeral 10 is a fold line of the square bottom bag.

FIG. 3 shows a state in which the simple box is folded by bending the fold line 7 of the top cover 2. When using this simple box, as shown in FIG.
is made to stand vertically, and the protrusion 8 of the bent piece 3 is fitted into the engagement hole 9 of the square bottom bag 5.

As described above, the present invention forms a folded piece around a square top lid having a hole, and forms one opposing folded piece so as to abut against the inner wall of the upper opening of the square bottom bag. , Attach the other opposing folded piece to the upper opening wall surface of the square bottom bag so that the fold line of the folded piece is located slightly above the upper edge of the square bottom bag, and make a hole from the center of the one opposing folded piece. This is a simple box in which a fold line is carved, a protrusion is protruded from the side of the folded piece, and an engagement hole is bored at the position of the square bottom bag corresponding to the protrusion. Since it is attached, the box can be provided at low cost and can be used as a disposable trash can. Moreover, since the present invention can be folded into a sheet shape, it is not bulky and takes up little space, making it convenient for transportation and storage. Furthermore, the present invention can be finished with a good appearance by adding a different color to the top lid, and can be used as an interior part. Moreover, the present invention can be easily assembled during use by a one-touch operation of unfolding the top cover into a flat shape and vertically standing the folded pieces.

In the present invention, the fold line of the folded piece is attached so that it is located slightly above the upper edge of the wall of the square-bottomed bag, so when opening the simple box, the position is outside the upper edge of the wall of the upper opening of the square-bottomed bag. The movement of the free folded piece to the outer position of the lower end of the side of the unattached piece is delayed than the movement to the outer position, and the folded piece is securely abutted against the inner wall of the upper opening of the square bottom bag from the inside, and the square bottom bag is closed. The box is not located outside the wall surface of the upper opening of the box, and the simple box can be reliably and easily opened into an angular shape.

Furthermore, in the present invention, a protrusion is provided on the side of the bent piece, and an engagement hole is bored at the position of the square bottom bag corresponding to the protrusion, so that the protrusion fits into the engagement hole and opens into a square shape. Ensure that the state is maintained.
