Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a cushion material used for wrapping or packaging articles.

``Prior Art'' Conventional cushion materials use four corner cushion pieces independently at the four corners, making them inconvenient to handle and use. Therefore, 1 at the four corners of the bottom plate.
Corner members were provided on the body, but although this was convenient for handling and use, the stacking volume was bulky when transporting and storing, making it difficult to reduce transport and storage costs.

``Problems to be Solved by the Invention'' The present invention attempts to reduce the stacked volume of cushion materials in which corner materials are provided at the four corners of a bottom plate.

``Means for Solving the Problems'' The present invention provides corner cushion pieces that stand upward along the orthogonal edges of the square plate at the four corners of the plate, and the orthogonal edges are used as two sides. The cushion material is characterized in that folding lines are formed at the four corners along the bottom sides of the right-angled triangle, and the cushion piece is formed so as to be bent downward at the folding lines as boundaries. It is composed of

"Function" Therefore, the four bottom corners of the rectangular article are fitted into the corner cushion pieces of the present invention, and the article is housed or packed in a packaging box with the bottom surface supported by the rectangular plate of the present invention. The rectangular article is stored and transported. The rectangular article mentioned above includes a plurality of stacked rectangular tiles for building floor surfaces. When the manufacturer transports the cushion material to the user, the corner cushion piece is folded downward from the folding lines formed at the four corners, and the square plate is turned upside down (up and down) in this state. The ridge pieces are raised at the four corners of the square plate, and the central part of the square plate can be brought into contact with the floor surface. Therefore, when the center portions of the same rectangular plates are stacked one after another, the raised cushion pieces at the four corners also fit into the ones on the lower tier and are stacked, so that they can be stacked with little gap between the upper and lower tiers.

"Example" Rectangular board or square board 1-4 by corrugated board
The corner portion 2 is formed by pipe molding on three orthogonal surfaces 3,
One side 5 of the corner cushion piece 6 having 4,5
The two orthogonal surfaces 3 and 4 are made to stand above the board 1 along the orthogonal edges 7 and 8 of the board 1 (this state is shown in FIG. 1).
At each of the four corners 2 of the square plate 1, a folding line 9 is formed along the bottom of a right triangle whose two sides are the orthogonal edges 7 and 8, and with the folding line 9 as a boundary, the cushion piece 6 is bent downward. (A reversed state of this is shown in FIG. 2.Also, as shown in FIG. 4, the square plate 1 and the corner cushion piece 6 can be integrally molded by pulp molding, but in this case, the corner One surface of the cushion piece 6 forms the four corners 2 of the rectangular plate 1.The one indicated by 10 in the figure is formed between the three orthogonal surfaces 3, 4, and 5 of the corner cushion piece 6, that is, the contact surfaces. The elastic groove, 11 in FIG. 4, is a raised receiving surface formed on the upper surface of the central portion of the rectangular plate 1, and 12 in FIG. 1 is an adhesive.

Therefore, when the square plate 1 is turned upside down and placed on the floor 13, the center part of the square plate 1 touches the floor 13 and the 4
As shown in FIG. 2, the corner cushion pieces 6 are bent from the folding line 9 and protrude upward, so that they can be stacked and hung on a rope as shown in FIG. 3 and transported to the user.

"Effect" Since the present invention is configured as described above, the square plate 1
and the corner cushion pieces 6 of the four corner portions 2 are integrally formed to easily cover and protect the bottom surface and the four bottom corners of a rectangular article (wrapping object), thereby providing a cushion material that is easy to use. In addition, since they can be stacked with little space and do not take up much space, they have the effect of reducing transportation costs.
