DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 to 6,
Reference numeral 1 denotes a tuner (hereinafter, referred to as a packaged object) which is used by being connected to a television receiver, which is formed by assembling an expanded corrugated cardboard having left and right sides cut as shown in FIG. It is protected by the produced buffer 2 and put in a packaging box 3 made of corrugated cardboard for packaging.

The buffer 2 will be described in detail.
The buffer 2 has a main body 4 made by assembling a single corrugated board, and two side plates 5, 5 made of the same corrugated board to close both ends of the main body 4. It is composed of An opening 6 is formed in the center of the main body 4 so that one of the left and right sides of the packaged object 1 can be fitted therein. 7, a bottom plate portion 8 connected to the lower end of the central plate portion 7, an upper plate portion 9 connected to the upper end of the central plate portion 7, and a bottom plate portion 8 connected to the bottom plate portion 8 in parallel with the central plate portion 7. A rear-side plate portion 10 that is vertically oriented and has a half width of the central plate portion 7; and the central plate portion 7 that is connected to the upper plate portion 9.
A rear plate 11 which is parallel to the upper and lower direction and is half the width of the central plate 7, and is approximately the same as the bottom plate 8 and the upper plate 9 which are connected to these rear plates 10 and 11, respectively. Plate portions 12 and 13 which overlap each other in width, and plate portions 14 and 15 which are respectively connected to the plate portions 12 and 13 and which have substantially the same width as the plate portions 10 and 11 and which overlap the inner surface of the central plate portion 7. ing. More specifically, a plate portion sequentially provided from the bottom plate portion 8
Plate part 1 connected in order from 10, 12, 14, and upper plate part 9
1, 13, 15 are bent together with the bottom plate 8 and the upper plate 9 so as to form a rectangular cylinder, and insertion pieces 16 and 17 formed at the tips of the plates 14 and 15 are connected to the central plate 7 and the bottom plate. A slit 18 formed along a fold curve with the portion 8 and along a fold curve with the central plate portion 7 and the upper plate portion 9;
It is configured so as to be fitted into and locked to the 19 to hold a rectangular cylindrical shape. Further, an L-shaped recessed portion is pushed into the L-shape across the plate portions 12 and 14 and at the position of the opening 6 of the central plate portion 7.
20 is formed, and is pushed into the L-shape over the plate portions 13 and 15 to form an L-shaped recess 21 at the position of the opening 6 of the central plate portion 7. 20, 21
Thus, it is configured to receive the side portion of the article to be packaged 1 fitted into the opening 6. By the way, the opening 6 is provided with plate portions 22 and 23 overlapping with the plate portion 12a of the concave portion 20 and the plate portion 13a of the concave portion 21 so as to be freely bent. At the tips of the plate portions 22 and 23, the plate portions 12a and 14a of the concave portion 20 are provided.
Slit 24 and the recess formed along the fold curve of
Insertion pieces 26 and 27 are provided which are fitted and locked in slits 25 formed along the bent curves of the plate portions 13a and 15a of the 21. The inserted pieces 26 and 27 are fitted and locked in the slits 24 and 25. By doing so, the plate portions 14 and 15
Are kept on the inner surface of the central plate portion 7. Further, a concave portion 28 is formed which is pushed inward over the bottom plate portion 8 and the rear plate portion 10, and is similarly pushed inward over the upper plate portion 9 and the rear plate portion 11. Recess 29 is formed. Further, slits 30 and 31 are formed at both longitudinal ends of the plate portions 12 and 13, respectively.

On the other hand, the respective plate portions 5 for closing the openings at both ends of the main body portion 4 are formed so as to be bent in a U-shape.
The slits 30 or 31 are provided in the bent pieces 5a, 5a.
Are formed, and the slits 5b of the bent portion 5a of the plate portion 5 are formed.
b, 5b are the plate portions at both ends of the main body portion 4
The buffer 2 is formed by fitting the bent pieces 5a, 5a of the plate portion 5 into the openings at both ends of the main body 4 so as to be engaged with the slits 30 and 31 of 12 and 13, respectively.

FIGS. 3 and 4 show the assembled shock absorber 2. Two shock absorbers 2 are prepared, and both sides of the article to be packaged 1 are fitted into openings 6 facing each other. In this state, it is put into a packaging box 3 made of a cardboard board and packaged. FIGS. 5 and 6 show a state in which both sides of the package 1 are fitted into the openings 6 of the buffer 2 facing each other, and the package 1 is recessed in the opening 6 of the buffer 2. Two
Sides are received by 0,21. In this manner, the article to be packaged 1 is placed in the corrugated cardboard packaging box 3 and packaged with both sides protected by the two buffers 2. Accessories and the like are stored in the recesses 28 and 29 as needed.
