Folding box

Abstract

The invention discloses a folding box. A base is provided with a plate-shaped body and two pairs of opposite protection edges surrounding the periphery of the plate-shaped body, and two pairs of opposite side plates are hinged to the protection edges of the base and can be folded relative to the base. Side plate hinge parts are arranged at the bottoms of the side plates, corresponding base hinge parts are arranged on the protection edges of the base, and the side plate hinge parts are hinged to the base hinge parts to hinge the side plates to the base. At least one pair of protection edges in the two pairs of opposite protection edges are internally provided with first closed cavities extending in the length extending direction of the protection edges and / or second closed cavities distributed in the plate-shaped body, and the second closed cavities protrude out of a main surface of the plate-shaped body. The folding box is high in strength, convenient to operate and easy to wash.

Description

technical field [0001] The present invention relates to containers, in particular to folding boxes. Background technique [0002] When the existing folding box is in use, the side panels should be relatively unfolded and upright, and the four side panels are interlocked to form a relatively closed space to accommodate the goods. After the goods are emptied, the box body needs to be recycled, in order to maximize cost savings , Fold the side panels of the box so that more boxes can be recovered in the same space. It should be easy to clean during the recycling process, especially when the folding box is used to load fresh fruits and vegetables, etc., cleaning after use is particularly important. At the same time, the box body must not only ensure the safety and reliability of the goods loaded in it during use, but also the side panels must be easily and quickly unlocked and folded when the goods in the box are emptied.

AI Technical Summary

Problems solved by technology

[0003] Existing folding box patents, such as the folding box disclosed in US7100786B2, the main structure of the box body is composed of thin walls and the arrangement of reinforcing ribs on its surface, and the installation position of the base hinge is single and weak due to the need for elastic installation.

After the base is formed, there are many unclosed cavities, and the concave parts of the grid ribs are prone to residue dirt during quick cleaning, which is inefficient

Especially at the edge protection position of the base, due to the hinge assembly of the side panels and the need for base molding, there are a large number of deep cavities in the base. When cleaning this area, a large amount of sewage will flow in, which is not easy to discharge and easy to breed bacteria.

[0004] In addition, this single-thin-walled structure has a single ability to resist bending and compression, especially at the hinge joint between the side plate and the base. At this time, the inner surface of the base is compressed and dented downwards. At this time, the side plate is hinged to the edge of the base due to its hinge, and the edge will bend inward with the depression in the base. The side of the side plate close to the hinge is also randomly protected. bending inwards and downwards due to traction

Therefore, in the existing folding box, when the load of the side plate near the hinge is increased, it cannot resist the inward deformation of the base guard, which makes the box base more likely to sag inward, causing the base guard to lie inward and further causing Deformation in the side panel

When using its multi-layer box for stacking, the goods on the upper layer will deform and sink with the thin wall of the base and the goods in the box below it will be under pressure, which will pose a safety hazard to the goods to a certain extent, and when the box is reused , the frequent high and low temperature environment of the box is used under stress and deformation, which can easily lead to fatigue damage and shorten the service life of the box
