うにしてある。As shown in FIG. 1, the ridge 3 is made of two parallel vertical pieces 3a so as to be light and use less material.
Is projected outward from the base surface, and the lower end thereof is connected by a horizontal connecting piece 3b.
Is set slightly higher than the lower end of the lower half 1, and when the containers A are stacked, the lower end of the lower half 1 is the lower container A
And an engaging portion that fits into the opening of the cover or a concave portion of the lid described later.

ように若干の隙間ができるため、嵌まり合いを生じない
入れ子状の容器Ａの積み重ねが行われる。As described above, the container A in which the ridges 3 are formed in the lower half 1 and the ridges 4 are formed in the upper half 2 has the ridges 3 and the ridges 4 as shown in FIG. When formed in the opposite manner, when empty objects are stacked so that the directions are left-right opposite on the lower side and the upper side, the concave streak provided on the upper half part 2 of the lower container A shown by a solid line in FIG. 4, the ridge 3 provided in the lower half 1 of the upper container A indicated by the two-dot chain line fits therein.
Is inserted into the lower container A until the lower end of the upper half 2 rides on the upper edge of the lower container A, and there is a slight gap between the containers A as shown in FIG. Stacking of the nested containers A that do not produce a fit is performed.

放した容器Ａの積み重ねが行われる。However, when the containers A containing the articles are stacked so that the right and left are aligned, the lower container A shown by a solid line in FIG.
The concave ridges 4 provided on the upper half 2 of the container A and the convex ridges 3 provided on the lower half 1 of the upper container A shown by the two-dot chain line are different from each other.
For this reason, the ridges 3 provided on the lower half 1 of the upper container A
Engages with the upper edge of the lower container A, the upper container A rides on the lower container A, and the containers A with the opening opened as shown in FIG. 8 are stacked.

た容器Ａの積み重ねが行われる。Further, when the container A in which the articles are bundled with a regenerator or the like and covered with the lid 7 is overlaid in a free direction, as shown in FIG. Since the engagement portion is accommodated, the upper container A is mounted on the lid 7 of the lower container A so as not to be displaced, and the containers A whose openings are closed are stacked as shown in FIG.
【００２２】なお、容器Ａの下半部１に形成される凸条

重ねができる。When the ridges 3 formed in the lower half 1 of the container A and the ridges 4 formed in the upper half 2 are formed in the same arrangement as shown in FIG. When the containers A are stacked so that the left and right are aligned, the lower half 1 of the upper container A is accommodated in the upper half 2 of the lower container A, and the nested stack of the empty containers A can be formed. When the containers A are stacked such that the left and right sides are opposite, the lower end of the upper container A rides on the upper edge of the lower container A, and stacking in which the opening of the container A containing the articles is opened can be performed.

る。When the container A has a heat insulating structure, it is effective in maintaining the freshness of stored articles and preventing deterioration. For this reason, the outer wall 9 and the inner wall 10 are formed so as to form a heat insulating space therebetween as shown in FIG. 6, and the sheet heat insulating material 11 such as styrene foam or polyolefin foam is sandwiched in the heat insulating space. A structure in which the outer wall 9 and the inner wall 10 are fitted and the joining edges 9a and 10a formed on the respective upper ends are overlapped and joined, or the outer wall 9 and the inner wall 10 are fitted so that a space exists between them. Then, the space is sealed by performing vibration bonding between the joining edges 9a and 10a, and a heat insulation structure using air existing in the space as the heat insulating material 11 is adopted.

を用いることが好ましい。The joining of the outer wall 9 and the inner wall 10 is easily performed by bonding with an adhesive, vibration welding, or the like, and these joinings are convenient for forming a heat insulating space between the outer wall 9 and the inner wall 10. . However, it is not easy to separate the outer wall 9 and the inner wall 10 when the container A is recycled by bonding by adhesion or welding. For this reason, the quick pin 13 made of a synthetic resin which can easily separate the joining between the outer wall 9 and the inner wall 10 is also provided.
It is preferable to use

１を容易に取り出すことができる。The joining of the joining piece 9a and the joining piece 10a by the quick pin 13 is performed by using two holes 15 each having a counterbore 14 for each of the pieces A, B, C, and D of the container A (FIG. 3).
Only by inserting the quick pin 13 into these holes 15 and the joining edges 9a and 10a can be joined with one touch. In addition, when recycling the container A, the quick pin 13 must be connected with a tool. If you use it to remove or cut it, the separation is done with one touch.
1 can be easily taken out.
