The lid R will be described with reference to FIG. 2 which is a plan view of the lid R and FIG. 3 which is a cross-sectional view taken along the line II in FIG. A lid flange 10 having a concave portion 10 ′ is provided near the edge of the lid R over the entire periphery of the lid R, and the concave portion 10 ′ of the lid flange 10 is fitted with the fitting rib 5 of the container body B.
Is configured to be inserted. Reference numeral 11 denotes a cover rib which is provided upright along the entire periphery of the cover R in the vicinity of the edge of the cover R. The cover rib 11 is configured to fit into the concave portion 6 'provided in. 12 is the lid rib 1
The reinforcing ribs are provided so as to be substantially orthogonal to 1 and can be appropriately protruded as needed.

Reference numeral 13 denotes a horizontal depression 1 having a continuous shape of a girder.
A recessed portion consisting of 3 'and a vertical recess 13 "is provided, and 14 is an island-shaped convex portion provided at a portion where the horizontal recess 13' and the vertical recess 13" in the shape of a girder cross. With this configuration, the horizontal direction and the vertical direction of the lid R (for convenience of explanation, the horizontal direction in FIG. 2 is compared with the concave portion provided concentrically along the peripheral edge of the conventional lid). A large number of undulations can be provided with respect to the horizontal direction (the vertical direction is referred to as the vertical direction), so that the bending rigidity of the lid R can be increased. It is preferable that the lid R is also integrally formed of a synthetic resin similarly to the container body B.

Next, the container stacking will be described with reference to FIG. 4, which is a partially enlarged sectional view showing a state in which the container main bodies B are stacked and the lid R is put on the uppermost container main body B. As shown in FIG. 4, the fitting rib 5 protruding from the horizontal flange 4 of the container body B2 located below fits into the recess 6 'of the lower flange 6 of the container body B1 located above. And the horizontal portion 4 "of the horizontal flange 4 of the container body B2 located below and the lower flange 6 of the container body B1 located above.
And a horizontal part 6 "of the container body opposes to form a kind of labyrinth structure, so that the airtightness between the container body B1 located above and the container body B2 located below is ensured, and the air ventilation with the outside air is effectively performed. Therefore, it is possible to solve the problem that stored foods, fruits, agricultural products, etc. are dried and the quality or the commercial value is reduced, and it is also effective in infiltration of foreign substances such as dust and garbage. Can be prevented.

The fitting rib 5 protruding from the horizontal flange 4 of the lower container body B2 is fitted into the recess 6 'of the lower flange 6 of the upper container body B1. The stacked container bodies B can be stably stacked in a stable state, so that the container bodies B can be prevented from collapsing and between the container body B1 located above and the container body B2 located below. Since no lid R is interposed in the container, more container bodies B can be stacked in a stable state.

In FIG. 4, a lid R is placed on the uppermost container body B1 which is stacked, and a fitting rib 5 of the container body B is provided in a concave portion 10 'of a lid flange 10 provided on the lid R. Inserted and horizontal part 4 "of horizontal flange 4

As shown by p, the packing member is arranged in the concave portion 6 'of the lower flange 6 of the container body B, whereby the airtightness of the further stacked container bodies B is ensured, and the air with the outside air is secured. Ventilation can be suppressed. Of course,
Such a packing member p can be arranged in the concave portion 10 'of the lid flange 10 of the lid R. Alternatively, instead of being arranged in the concave portion 6' of the lower flange 6 of the container body B, the horizontal flange of the container body B can be used. 4 can be attached to the fitting rib 5.

[0014]

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects. Since the container bodies are stacked one on top of the other via a labyrinth structure, the airtightness between the container bodies can be improved, and the intrusion of foreign matter such as dust and dirt can be reliably prevented.

Since the container bodies can be stacked without interposing a lid while maintaining airtightness, a stable stacking can be ensured and more container bodies can be stacked.

[0016] Stacking can be carried out simply by covering only the uppermost container body with a lid, so that the workability of stacking is greatly improved.

Since the girder-shaped depression is provided on the lid and the island-shaped projection is provided at the intersection of the depression, the bending rigidity of the lid can be increased, and the strength of the lid can be greatly increased.
