Description

The utility model relates to food storage and transportation devices.

Known "Box" RU 2110456 [1], The box is made of plastic, open on top, has a tapering body with a ribbed bottom and inclined side and end walls. In one of the end walls, there is a protrusion facing the inside of the box.

The disadvantage of the known design is low strength and rigidity.

The closest to the claimed technical solution is "Container box with a continuous stiffening element" RU 2529100 [2], containing a bottom, two end walls adjacent to the bottom, two side walls, stiffeners on the walls.

The known device has greater strength and rigidity compared to [1] due to the presence of a continuous rib.

The disadvantage of the known design is low stability with a small horizontal deflection when stacking boxes.

The technical result of the proposed solution is to increase the strength of the box.

The technical result is achieved by the fact that the box containing the bottom, two end walls adjacent to the bottom, two side walls, stiffeners on the walls, is characterized by the fact that on the upper edges of the walls there are recesses in pairs, each recess has a flat section located parallel and below the main the plane of the upper surface, horizontally oriented stiffeners are located along the upper edges of the walls.

The recesses are located mirrored symmetrically relative to the longitudinal plane of the box, located vertically along the long side and mirrored symmetrically relative to the transverse plane located vertically along the short side of the box.

Implementation of the invention:

FIG. 1 shows a general view of the box, FIG. 2 shows two stacked boxes, where:

1 - bottom;

2 - end walls;

3 - side walls;

4 - recesses;

5 - stiffeners along the upper edges of the walls;

6 - stiffeners along the lower edges of the walls;

7 - horizontal stiffeners along the central parts of the walls;

8 - vertical stiffeners

9 - holes;

10 - double walls in the corner parts of the walls;

11 - flat section of the excavation, parallel to the main site;

12 - inclined section of the excavation;

13 is the main upper platform.

The device operates as follows:

The box consists of a bottom 1, to which the end walls 2 and side walls 3 are adjacent. On the upper edges of the walls there are recesses 4 for placing the crossbars, which are not part of the box and can be made from scrap materials - sticks, pieces of bars, etc. ... The box located on top rests not only on the upper edges (ends) of the side walls of the underlying box, but also on the crossbar, which allows the stack to remain stable even when the upper box is displaced relative to the lower one until the center of gravity of the overlying boxes with loads goes beyond the perimeter lower drawer supports. Each recess has a flat section of the recess 11 parallel to the plane of the main platform 13 and a pair of inclined sections 12 on the sides of the recess, between the flat section and the main upper platform 13. Stiffeners along the upper edges (ends) of the walls are made with a flat outer surface forming the main platform and platforms above the recesses. Stiffeners are directed parallel to the bottom of the box. The area of the main site is significantly larger than the area of the excavation sites. The recesses extend from the outer side of the box to the inner, dihedral angles are formed between the planes of the recesses, the edges of which are directed from the inner side to the outer side of the side wall of the box perpendicular to the longitudinal plane of the box. In the case of mutually perpendicular walls of the box, forming a parallelepiped, said edges are perpendicular to the walls of the box. Stiffeners along the upper edges of the walls 5 and stiffeners along the lower edges of the walls 6, in addition to increasing the stability of the stack, increase the strength and rigidity of the upper and lower parts of the walls, respectively, due to the creation of the upper and lower bands of strength. Horizontal stiffening ribs 7 along the central portions of the walls increase the strength and rigidity of the central portions of the walls to form a central belt of rigidity. Vertical stiffeners 8 adjoin horizontal stiffeners along the central parts of the walls, stiffeners along the upper edges of the walls, stiffeners along the lower edges of the walls, mechanically tying them together, which allows you to optimally distribute mechanical bending forces, further increasing the strength of the box. Holes 9 allow whey to drain when cheese, curd mass is placed in a box, or to ventilate the contents when vegetables are placed in it. In addition, the presence of holes increases the wall thickness and further increases the strength of the box while maintaining weight. Double walls 10 in the corner parts of the walls make it possible to increase the strength of the box, since it is in the corner parts that mechanical overvoltages are concentrated. Designing the drawer with a slight upward extension will make it easier to remove hardened cheese or other products from the drawer.

EFFECT: increased strength of the box is achieved by the presence of stiffeners on the upper edges of the walls and in pairs located notches that increase the strength and stability under bending forces of the side walls, and, as a consequence, of the entire box. An additional increase in the strength of the boxes themselves is achieved by a system of mutually perpendicular stiffeners on the walls.

Industrial applications. The utility model can be successfully used for the manufacture and operation of strong and stable boxes.
