Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a U-shaped laminate formed by winding a single stage.
[0002]
[Prior art]
In the conventional U-shaped laminate, the side walls formed by bending from both sides of the back wall are in a parallel positional relationship.
[0003]
[Problems to be solved by the invention]
The conventional product has poor fitting and fixing ability because the side walls are parallel to each other, and if the laminate is not stored in the outer box in the fitted state and the laminate is not fixed, it may fall off and the edge area will swell In the package that has become, it became an unstable package to wiggle. The object of the present invention is to solve the problems of the prior art.
[0004]
In order to achieve the above-mentioned object, it consists of laminated single-sided corrugated paper, and by narrowing the interval between the leading edges of the a wall and the b wall that are bent from both ends of the back wall in parallel with the corrugated ridge line of the single-sided corrugated paper , The base of wall a and wall b acts as a spring to pinch the packing material and prevent it from falling off.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The product of the present invention is manufactured using single-sided corrugated paper (corrugated paper with a flat plate bonded on one side of a corrugated sheet) as a raw material, the opening is the front, the a wall is the top, the front back (front and back), top and bottom (top and bottom) ) Positional relations such as left and right are displayed with reference to the front, and the folding direction described in the mountain or valley fold is displayed with reference to the outside.
[0006]
In FIG. 1 of the upper right front perspective view, the top and bottom ends of the back wall 1 are folded forward to form the a wall 2 and the b wall 3, and the opening 4 is formed between the leading edges of the a wall 2 and the b wall 3. If the vertical width of the opening 4 is obviously narrower than the vertical width of the inner surface 5 of the inner surface of the inner wall 1, the manufacturing method of the present application will be described in detail. The molding method according to the prior art is to apply a paste to the corrugated ridge of one step and wind it into a cylindrical shape, put it in a U-shaped female mold in a state where the glue does not dry (raw dry), In order to make a U-shape by pressing the mold into the shape of this application, with the glue of the U-shaped molding buffer being dry, press the isosceles triangle or trapezoidal mandrel on the inner surface and open the opening It is desirable to wind the string while the 4 is narrowed and dry it. Another method is to use a trapezoidal shape when forming a U-shape. It may be a method of narrowing the openings 4 in using a mold.
[0007]
In FIG. 2 of the right-hand side view of the use state, in the case where the edge region of the package 6 is swollen, the narrowed opening 4 sandwiches and fixes the package 6 from above and below. Since the base part (between the back wall 1) and the b wall 3 acts as a spring, it helps the opening part 4 to close.
[0008]
【The invention's effect】
Since the opening is narrowed, the base of the wall a and wall b acts as a spring to prevent the package from being pulled out, and even if the package has a bulging edge, b The leading edge with the wall sandwiches the packaged item, so it can be packed in a stable state without being overgrown.
