Description

[Detailed Description of the Invention] The present invention relates to a cushioning material used in the corners of product packaging boxes.

Traditionally, reinforcing materials or cushioning materials have been used at the corners of packaging boxes to protect products, and with the development of synthetic resin manufacturing methods and the expansion of fields of use, styrofoam materials have become widely used for these purposes. It has come to be used extensively.

On the other hand, because the incineration of Styrofoam is closely related to the pollution problem that has become a particular problem recently, companies that ship large quantities of products are currently being forced to change the material of their packaging cushioning materials. .

Focusing on this point, the present invention uses corrugated paper, which does not produce toxic gas even when incinerated, and creates a form that can be easily folded into a single sheet and used as reinforcing and cushioning material for the corners of packaging boxes. It is something.

The gist of the present invention will be explained below with reference to the drawings.

FIG. 1 is a developed view of the cushioning material according to the present invention. They are connected to each other via curves A, 3, A, and 1, and each oblique side of the triangular pieces L, O, and W is provided with an obliquely elongated edge edge, Y, Y, and E through folded lines 10, 11, and 13, respectively. , connect the edges of one edge, y, y, and y, respectively, through folding lines 9, 12, and 14, to make a triangular piece in the shape of a right-angled isosceles triangle, connect the hypotenuses of y, tsu, and make the triangular piece, y.

A notch of width N is provided along two sides sandwiching the right angle of A, and a fan-shaped circular arc portion centering on A is provided on sides A and 4 of the triangular piece W through folding lines A and 7. , and connect the hypotenuse of the right-angled isosceles triangular protrusion N to the sides A and 2 of the triangular piece R through a folding line, and further connect the oblique side of the right-angled isosceles triangular protrusion N to the sides A and 2 of the triangular piece A, and further form a sector-shaped part from the protrusion N to the center A. The gist of the present invention is a packaging cushioning material characterized by a structure in which a corrugated cardboard plate cut into sections is folded so that the sections are inserted into each other so that the triangular trilateral parts support each other. It is something.

To manufacture the cushioning material of the present invention, use a square-shaped corrugated paperboard with side length a, draw phase lines 1, 2 and 3, 4 that divide it into four equal parts, and 2, connect the center point 5 and point 2, and then connect the point 5 and the center A of the whole.

An arc (
90°), cut out the outside defined by points 2, 5, 6° 7.4, and draw arcs 6, 8 and straight lines 8. A and straight line 6
．． Cut out the part surrounded by A and leave the arc part E.

In the figure, take the same dimensions (it is better to make the insertion side a little smaller) that correspond to when folding, and cut out the notch at a constant depth.

Dividing the quadrilateral into four equal parts, centering on the diagonal line of the three parts of each quadrilateral, draw phase lines 9 and 10 with the distance opening that will be the thickness during assembly.
11.12 and 13.14, and cut out a triangular shape at each end as shown.

Bend all the previous phase lines at right angles as valley folds, bend them sequentially as shown in Fig. 2, insert the arc part E shown in Fig. 1 between the triangular piece and the triangular piece, When assembled by inserting the protruding part E between the triangular piece W and the triangular piece A, the configuration shown in Fig. 3 is obtained, with the circular arc part E being sandwiched between the right side of the triangular piece and the surface of the triangular side L, and The protruding part is sandwiched between the upper side of the triangular piece and the surface of the triangular piece and is fixed respectively, so that the triangular piece and the triangular piece are firmly connected.

Furthermore, by adhering the internal seams with adhesive tape C or the like, the product is completely completed.

As explained above, the present invention uses a single piece of cardboard as a material and is constructed so that the thick triangular bodies support each other by bending it, which significantly increases its rigidity and makes it strong. At the same time, the air that exists between each near body (thickness) acts as a buffer and supplements the impact resistance.
It has sufficient qualities as a cushioning material or reinforcing material for packaging, and can be produced simply and at low cost.

Claims (1)

[Claims for Utility Model Registration] Three right-angled isosceles triangles, the first triangle, the second triangle, and the third triangle have their right-angled vertices touching each other at the center point A, and the second triangle A first triangular piece O and a third triangular piece Wa are connected to each other via folding lines A, 3, A, and 1 on both sides of the piece O, and furthermore, the first triangular piece O, the second triangular piece O, and the third triangular piece O are An elongated first edge edge, a second edge edge edge, and a third edge edge edge each having a constant width are connected to each hypotenuse of the triangular edge warp via folding lines 10, 11.13, and the first edge edge edge, On the opposite side of the second edge piece and the third edge piece, there is a fourth triangular piece in the form of a right isosceles triangle, a fifth triangular piece, and a sixth triangular piece, respectively, via folding lines 9, 12, and 14. Connect the hypotenuses of and form the fourth, fifth and sixth triangular pieces. A cutout portion of a constant width is provided along the two sides that sandwich the right angle of the edge, and the side A and 4 that are not connected to the second triangular piece O and the third edge piece of the third triangular piece W are bent. The fan-shaped circular arc portions E centered on the center point A are connected via the edges A and 7, and the first
The side A and 2 that are not connected to the second triangular piece O and the first edge single edge of the triangular piece L are connected to the oblique side of the right-angled isosceles triangular protrusion N via folding lines 2 and 8, and further the protrusion A corrugated board in the shape of a fan-shaped portion centered on the center point A is folded at right angles to the valley fold on all the above folding lines, and the above circular arc portion E is folded into the first triangular piece and the fourth triangular piece. A packaging cushion characterized in that the protrusion is inserted between the pieces and the protrusion is inserted between the third triangular piece and the sixth triangular piece so that the triangular pieces support each other.
