Description

[Detailed Description of the Invention] The present invention relates to a packaging body in which a product (an object to be packaged) is covered with a cushioning body from both ends, and these are wrapped around an exterior body made of a corrugated board to package the object to be packaged.

Various packaging bodies of this type have been known in the past, and one example is a cushioning body made of styrene foam that fits over both ends of the packaged body, with L-shaped notches provided at four corners of the outer end side. Some cases have an L-shaped engagement plate formed on the exterior body so as to engage with each of the notches, but in order to engage the engagement plate with each of the notches, each retaining plate is manually pressed. It was necessary to push it inward at right angles, making the packaging process cumbersome.

This invention was made to deal with such problems,
The present invention will be explained below based on drawings showing an example of implementation.

In the figure, reference numeral 1 denotes an exterior body made of a corrugated board, in which a cushioning body 3 made of foamed polystyrene is fitted onto both ends of a packaged body 2 through recessed portions 3a, and is integrally wrapped therein.

Notches 4 in the shape of a right-angled isosceles triangle are formed at some of the four corners on the outer end side of the buffer body 3, and the exterior body 1 is formed along the slope 5 of each of the notches 4. Engagement plate portions 6 are formed at both ends of the bent portion.

This engagement plate portion 6 includes both front and rear plate portions 7, which constitute the exterior body 1.
8 and bottom plate part and top plate part 10 [top plate forming flap 11
．． 12) is formed so as to span between adjacent plate parts at both ends, and the folding lines of each of the plate parts 7 to 10 are formed between the engagement plate parts 6, 6 at both ends.

Further, a cut groove 13 is formed between each retaining ply plate part 6 and the end of the folding line, and furthermore, two folding lines 14 and 14 are formed at both ends of each engagement plate part 60. When the plate part 6 is bent at a right angle to the adjacent plate part, the engagement plate part 6 is formed to be inclined between the two plate parts.

At that time, the engagement plate part 6 forms the hypotenuse of the right triangle, but since the total length of the engagement plate part 6 is the same length as the base + height of the right triangle, the length of the hypotenuse is the same as the length of the hypotenuse. The extra length can be absorbed between the two folding lines 14 and 14 at each end.

By the way, the upper plate part 10 has upper plate forming flaps 11 which are connected to the upper ends of the front plate part 7 and the rear plate part 8 and overlap each other.
．． 12, and the upper flap 12 is provided with an insertion piece that fits into a groove 15 formed on the folding line between the lower flap 11 and the front plate part 1, and the lower flap 11
A locking piece 17 in the shape of ``] is cut out between the front plate part 7 and the front plate part 7. This locking piece 17 is fitted into a groove 18 formed on the folding line between the flap 12 and the insertion piece 16. I'm starting to get it.

Next, the learning order will be explained.

First, shock absorbers 3 made of styrofoam are attached to both ends of the packaged object 2.
3 is placed on the bottom plate part 9 of the outer package 1, and the outer package 1 is wrapped around the packaged object and the buffer bodies 3, 3. As a result, each of the engagement plate parts 6 is attached to the buffer bodies 3, 3. The engagement plate portion 6 abuts along the slope 5 of each notch portion 4.
The waist exterior body 1 is engaged with the side surface 4a of the body 1, and the waist exterior body 1 is engaged with the shock absorbers 3, 3.

Finally, assembly is completed by fitting the insertion piece 16 of the upper flap 12 into the groove 15 and fitting the locking piece 17 into the groove 18.

By the way, in the embodiment described above, two folding lines 14.14 are formed at each end of the engagement plate part 6, and these folding lines 14.14
Although the extra length with respect to the hypotenuse of the right triangle is absorbed by the gap, it is also possible to provide two folding lines at only one end to absorb the extra length.

Furthermore, instead of providing the notch 4 on the outer end side of a part of the corner of the buffer body as shown in the drawings, it may be provided on the inner end side or the middle part (edge) of a part of the corner, in which case the engagement plate Needless to say, the position of section 6 will also change.

The packaging body of the present invention can be implemented as described above, and the engagement plate portion of the exterior body can be held in the notch of the buffer body by simply wrapping the exterior body around the packaged body and the buffer bodies at both ends. There is no need to manually push the engaging plate portion inward as in the conventional case, and the packaging operation can be performed extremely easily.

1. Moreover, since the engagement plate portion is provided with two folding lines at least at one end thereof, the length of the triangular notch portion relative to the oblique side of the right triangle can be absorbed.
