Reference numeral 2 denotes a peripheral wall portion formed from a long wall portion 2a and a short wall portion 2b facing each other, which are slightly inclined outward from the peripheral edge of the bottom portion 1. An appropriate number of mounting members 3 are formed on the opposing long wall portions 2a and short wall portions 2b of the peripheral wall portion 2, and the mounting members 3 partially cover the peripheral wall portion 2 and the bottom portion 1, respectively.
It is formed by bulging inward of the packing tray, and therefore, the space below the mounting member 3 is formed.

In this embodiment, the mounting member 3 described above is used.
However, two are formed on each of the opposing long wall portions 2a, but three or more can be formed. Further, one mounting member 3 is formed on each of the opposing short wall portions 2b, but the mounting member 3 may be omitted from the short wall portion 2b if necessary. Alternatively, two or more mounting members 3 are provided on the opposite short wall portions 2b, respectively.
Can also be formed. The number of the mounting members 3 depends on the size of the packing tray and the size and weight of the articles to be packed,
It can be decided in a timely manner.

The mounting member 3 has an upper horizontal portion 3a extending substantially horizontally from the vicinity of the upper end of the peripheral wall portion 2 and a direction below the tip of the upper horizontal portion 3a and away from the upper horizontal portion 3a. An inclined portion 3b extending in a vertical direction, a movement restricting wall portion 3c extending substantially vertically from a lower end of the inclined portion 3b, a mounting portion 3d extending horizontally from a lower end of the movement restricting wall portion 3c, A substantially vertical vertical portion 3e extending downward from the tip of the portion 3d
A lower horizontal portion 3f extending from the lower end of the vertical portion 3e in a substantially horizontal direction, and a mounting member 3 that extends from the tip of the lower horizontal portion 3f to the bottom portion 1 and extends toward the bottom portion 1 A skirt portion 3g that is inclined so as to gradually move away from the lower horizontal portion 3f, and an opposing side wall portion 3h that is substantially perpendicular to the long wall portion 2a and that is connected to the lower horizontal portion 3f.
It is composed of and. In addition, the movement restricting wall portion 3 is provided at the corner formed by the movement restricting wall portion 3c and the placing portion 3d.
A concave portion 3i is formed along c, and the placing portion 3d is formed in a substantially truncated pyramid shape by forming such a concave portion 3i. At least the lower horizontal portion 3f,
It is disposed so as to surround the peripheral portion of the mounting member 3, and in the present embodiment, extends to the peripheral wall portion 2.

As described above, the lower horizontal portion 3f is formed on the mounting member 3 so as to surround the mounting member 3, and the vertical portion 3e is formed.
Since the step portion is formed by the lower horizontal portion 3f and the lower horizontal portion 3f, when the drop impact is applied to the packing tray, the placing member 3 is easily deformed, so that the article placed on the placing portion 3d is easily deformed. The impact of can be absorbed and relaxed.

Further, as described above, the movement restricting wall portion 3c
By forming a concave portion 3i at a corner between the mounting portion 3d and the mounting portion 3d, the mounting portion 3d formed in a substantially truncated pyramid shape has a horizontal portion 3d.
1, a vertical portion 3e extending downward from four edges of the horizontal portion 3d1, a side wall portion 3h facing the side wall portion 3 and a side wall 3 on the side of the recess 3i.
d2, and further, the four corners formed by the horizontal portion 3d1 and the vertical portion 3e, the side wall portion 3h, and the side wall 3d2 on the concave portion 3i side are formed with rounded portions. The mounting portion 3d is formed in a mountain shape having a horizontal portion 3d1. By forming the mounting portion 3d into a mountain shape having such a horizontal portion 3d1, the mounting portion 3d
When a drop impact is applied to the article placed on, the placing section 3d is deformed as compared with the case where the concave section 3i is not formed or the four corners are angularly formed. Since it is easy, the impact on the article placed on the placing section 3d can be absorbed and alleviated.

Further, as described above, the mounting member 3 is formed below the mounting member 3 so as to surround the mounting member 3 extending to the bottom 1 and is inclined so as to gradually move away in the direction of the bottom 1. Since the skirt part 3g is formed,
When a drop impact is applied to the packing tray, the skirt portion 3g is deformed, and the impact on the article placed on the placing portion 3d can be absorbed and alleviated.

In the region of the long wall portion 2a in which the placing member 3 is arranged, the width of the placing member 3 (the interval between the side walls 3h facing each other substantially perpendicular to the long wall portion 2a) is equal to or slightly larger than that. A wide concave portion 4 is formed. By forming such recesses 4, the long wall portion 2a of the packaging tray in which the articles are packaged is provided with the placement section 3d on which the articles are placed even if an impact is applied by dropping or the like. Since the impact can be prevented from being directly applied to the placing member 3, the impact on the article can be mitigated. The recess 4 may be formed in the short wall portion 2b in which the mounting member 3 is arranged, if necessary. In addition, an elastic member such as a string or a band for pressing the articles packed by the packing tray can be inserted into the above-mentioned recess 4.

The long wall portion 2a located between the mounting members 3
A part of a lower end (a boundary line with the bottom portion 1) of the central region 2a ′ of is formed in a shape protruding outward. In this embodiment, the central portion 2a1 at the lower end of the central region 2a 'projects outward, and the side portions 2a2 located on both sides of the central portion 2a1 are inclined toward the other long wall portion 2a. Then, the upper end 2 of the central region 2a 'of the long wall portion 2a
The lower end composed of a3, the central portion 2a1 protruding outward, and the inclined side portion 2a2 is connected by a bending wall 2a ". By forming such a bending wall 2a", the article is packaged. When the packing tray is dropped or the like, the impact is particularly high, the deformation is easy, and the strength and bending rigidity of the central region 2a ′ of the long wall portion 2a are increased, so that the tray is placed on the placing portion 3d. It is possible to mitigate the impact on the existing article.

The bottom portion 1 includes a contact area 1a formed by bulging the bottom portion 1 downward, which comes into contact with the floor or the like when the packing tray is placed on a flat floor or the like, and a contact area. It is formed in two steps with a non-contact area 1b that does not contact the floor or the like formed in the peripheral area of 1a. The contact region 1a bulging downward includes a central cross-shaped convex portion 1a1 located in a central region of the bottom portion 1, corner convex portions 1a2 located near four corner portions of the bottom portion 1, and a central cross-shaped convex portion 1a1. And a strip-shaped connecting convex portion 1a3 for connecting the corner convex portion 1a2.
The central cross-shaped convex portion 1a1 located in the central region of the bottom portion 1 is
A portion 1a1 ′ along the short wall portion 2b extending substantially below a central region 2a ′ of the long wall portion 2a located between the mounting members 3 formed on the opposite long wall portions 2a, and a short wall facing the portion 1a1 ′ It is formed by a portion 1a1 ″ along the long wall portion 2a, which extends substantially below the mounting member 3 formed on the portion 2b.

As described above, the bottom portion 1 is connected to the contact area 1a.
And the non-contact area 1b are formed in two stages, so that when the packing tray in which the articles are packed falls from the bottom portion 1,
Compared to the conventional packaging tray having such a stepless bottom, the impact on the article can be mitigated. Further, by forming the corner projections 1a2 near the four corners of the bottom part 1, it is possible to absorb the shock caused by the falling of the packing tray from the corners, and thus to mitigate the shock to the article. You can Further, a strip-shaped connecting convex portion 1a3 for connecting the central cross-shaped convex portion 1a1 located in the central region of the bottom portion 1 and the corner convex portions 1a2 located near the four corner portions of the bottom portion 1
By forming the packaging tray, when the packaging tray containing the articles is placed on the roller conveyor and transported, the relatively small corner protrusions 1a2 fall between the roller conveyors, which hinders smooth transportation. It is possible to prevent the packaging tray in which the articles are stored or the articles are stored from tilting. In addition, when the packing tray is not conveyed by the roller conveyor, the band-shaped connecting convex portion 1a3 may be omitted.

When the article A is packed using the above-mentioned packing tray, as shown in FIG.
The vertical side wall portion a1 corresponds to the movement restricting wall portion 3c of the mounting member 3.
It is placed on the placing portion 3d of the placing member 3 of the packing tray so as to come into contact with or approach. Further, although a cover (not shown) is placed on the upper part of the article A, this cover may be a packaging tray having the above-described configuration, and in this case, the packaging tray is placed upside down. Next, an elastic member such as a cord or band is attached to the recess 4 formed in the long wall 2a.
And the like, the packing tray, the article A, and the cover are tightened together by the tightening member. In this way, after packing the article A, the packing tray, the article A
And the entire cover is covered with a film such as a heat-shrinkable film. Of course, it is also possible to cover only the article A with a film such as a heat-shrinkable film before packaging and to omit coating with the film after packaging. As described above, in the article A, the vertical side wall portion a1 has the movement restricting wall portion 3 of the mounting member 3.
By arranging the article A so as to come into contact with or approach c, even if the article A tries to move in the lateral direction, the movement restricting wall portion 3
Since it comes into contact with c and its movement is suppressed, the article A can be packaged and transported in a stable state.

The above-mentioned packing tray is integrally molded of synthetic resin by injection molding, blow molding, vacuum molding or the like.

[0019]

Since the present invention has the constitution described above, it has the following effects.

Since the lower horizontal portion is formed below the placing portion on which the article of the placing member is placed, the placing member is easily deformed, and accordingly, the article placed on the placing member can be easily deformed. Shock can be absorbed and relaxed.

Since the skirt portion extending to the bottom portion is formed below the lower horizontal portion, the skirt portion is deformed when the packing tray is subjected to a drop impact, and thus is placed on the placing member. It is possible to absorb and mitigate the impact on the articles.

Since the placing portion on which the article of the placing member is placed is formed in a mountain shape, the placing portion is easily deformed, and accordingly,
The impact on the article placed on the placing member can be absorbed and alleviated.
