Each of the buffer portions W is connected to both longitudinal edges of the main body portion V via trapezoidal folds C.

The trapezoidal fold C includes a fold C1 in contact with both edges of the rectangular bottom surface 1 and a diagonal fold C2 extending outwardly from both ends thereof at an angle of 45 degrees with respect to the fold A.
C2.

As shown in FIG. 4, the buffer portion W has a total of four parallel folds for bending this portion into a substantially rectangular tube shape in a direction perpendicular to the longitudinal direction of the main body portion V. D1 to D4 are provided. As a result, the buffering portion W has the fitting recess S
The end face inner wall 6, the top face 7, the end face outer wall 8, the bottom face 9, and the engagement piece 10 which are the side walls in the longitudinal direction are formed separately through folds.

The end face inner wall 6 is provided with a fold E extending from the end of the parallel fold A and having a fold in the opposite direction. Further, cuts 11 reaching the fold E are provided at both ends of the parallel fold D1 in a cut shape.

As a result, trapezoidal standing auxiliary pieces 12 are formed on both sides of the inner wall 6 of the end face and are surrounded by the oblique fold C 2, the fold E and the cut 11. The fold C1 has a fold in the same direction as the parallel fold A.

As shown in FIG. 4, the engagement piece 10 serves to bufferly support both ends of the main body V bent in a gutter shape from the back side thereof, It serves to fix the shape. Therefore, a rectangular notch 13 for fitting the fitting concave portion S is provided on the edge side of the engagement piece 10.

Next, a procedure for folding the paper packing 201 from the cardboard 101 will be described. First, as shown in FIG. 3, the main body portion V is bent in a gutter shape while the outer wall 3 is folded over the outer side of the inner wall 2 according to a predetermined folding habit. Then, the end face wall 6 is also erected from itself by the action of the erecting auxiliary piece 12 provided with the oblique fold C2 provided on the buffer portion W side.

Next, the main body portion V (not shown) which has been folded into a gutter shape is turned over, and each buffer portion W connected to both ends thereof is
As shown in FIG. 4, when the engagement piece 10 is engaged with each of the fitting cuts 4 provided on the outer wall 3 of the main body V while being bent into a substantially rectangular cylindrical shape, the paper packing 201 is formed. Are folded at once, and the folded shape is securely fixed.

As shown in FIGS. 4 and 6, the folded paper packing 201 is formed with a fitting recess S for fitting the side end portion of the packaged article 300 for buffer support. At both ends of the fitting concave portion S (that is, the main body portion V), buffer portions W which are bent into a substantially rectangular tube shape are engaged with each other in an orthogonal shape.

As shown in FIG. 4, the bottom surface 1 of the fitting concave portion S is cushioned and supported by the engagement piece 10 while being lifted from the bottom surface 9 of the buffer portion W.
The longitudinal side wall of the fitting concave portion S has an end face inner wall 6,
A double wall structure with the end face outer wall 8 is provided.

Further, as shown in FIG. 4, both ends in the cylinder axis direction of each buffer portion W project outside the outer wall 3 of the fitting concave portion S, and serve as buffer ribs. Will fulfill. Therefore, folded paper packing 201
Despite its relatively simple form, it exhibits extremely excellent cushioning performance.

Next, the effect of the provision of the cutouts a at the respective corners of the outer wall 3 of the main body V will be described. As shown in FIG. 6, the packing article 300 has a paper packing 201 (or a paper packing 202 described later) on each of both side ends.
And placed in a cardboard box 400. Incidentally, the packaged article 300 may of course be placed sideways. In this packing state, the corners of the buffer section W bent into a substantially rectangular cylindrical shape are applied to the corners in the cardboard box 400.

This corner portion is a place where the impact force from the outside is likely to be intensively received during cargo handling. If this portion is buckled and deformed, the deformation force is applied to the corner portion of the buffer portion W. Will be extended. At this time, if the notch a is provided at the corner of the outer wall 3, the corner of the buffer W is relatively easily buckled and deformed, so that the impact force is effectively attenuated and the main body V ( It is prevented from directly reaching the fitting recess S).

Next, FIG. 5 shows another embodiment of the present invention, in which a portion of one corrugated cardboard 102 serving as a material of the paper packing 202 of this embodiment shown in the lower part of FIG. It is a top view. This paper packing 202 is different from the above-described paper packing 201 in that, as shown in FIG. 6, two meshing pieces 10 are stacked in order to increase the cushioning property or the load resistance. It is in.

That is, the cardboard 102 is made up of the cardboard 101
Is provided with a form in which a meshing piece 10 of the same shape is connected symmetrically via a fold F to each of the meshing pieces 10. When the two packing pieces 10 are folded up when the paper packing 202 is folded up, the ability to cushionly support the fitting recess S from the back side thereof is further enhanced.
If necessary, three or more meshing pieces 10 may be overlapped.
