Folding box

Abstract

The invention discloses a folding box. The folding box comprises a base and two pairs of opposite side plates; a protecting edge is arranged at the outer periphery of the base; and the side plates are hinged to the base, and can be folded corresponding to the base. The side plates are double-glaze side plates; and cavities are formed in the lower edges of at least one pair of side plates. When the folding box is upright, the lower edges of one pair of side plates and the lower edges of the other pair of side plates are connected to form a frame; and the frame is hinged to the base through a hinge to form a reinforcing component for resisting sinking of the base and recessing of the protecting edge. The folding box can reduce the dirt residuals in repeated use to the greatest extent after cleaning, promotes the cleaning efficiency, improves sinking of the base after loading of a box body, solves the problem of collision damage between objects caused by sinking of the base due to pressing between upper and lower layers of goods when folding boxes are stacked by multiple layers, and solves the potential safety hazard of warehousing storage caused by stacking failure due to deformation of the side plates after pressing of the side plates due to stacking of multiple layers of boxes bodies when the boxes bodies are smaller in wall thickness and higher in folding rate.

Description

technical field [0001] The invention relates to a container, in particular to a folding box. Background technique [0002] The existing folding box has a fixed thickness and height of the side panels. When 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 needs to To be recycled, in order to maximize cost savings, the side panels of the box are folded so that more boxes can be recycled in the same space, and the recycling process should be easy to clean, especially when the folding box is used for loading Cleaning after use is especially important for fresh vegetables and fruits, and 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 , and the exist...

[0002] The existing folding box has a fixed thickness and height of the side panels. When 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 needs to To be recycled, in order to maximize cost savings, the side panels of the box are folded so that more boxes can be recycled in the same space, and the recycling process should be easy to clean, especially when the folding box is used for loading Cleaning after use is especially important for fresh vegetables and fruits, and 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 , and the existing folding box patents such as US20090101640A1, the main structure of the side panel of the box body is composed of thin walls and the arrangement of reinforcing ribs on its surface. One of the side panel structures, the grid ribs are easy to remain in the recessed parts during quick cleaning dirt, inefficiency

Second, this single-thin-wall structure has a single ability to resist bending and compression, especially at the hinged part of the side plate and the base. When carrying goods, the inner surface of the base is pressed 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, and the side of the side plate close to the hinge is also randomly protected. Deformation and bending inwards due to the traction of the sides

[0003] Therefore, when the edge of the base is at a limited height, the side plate, especially near the lower edge of the hinge, can support and correct the depression in the base and the inward deformation of the edge. Therefore, the existing invention patent, the side plate The part near the hinge is composed of a single thin wall. When the load is increased, it cannot resist the deformation of the base guard inwards, which makes the inside of the box base sag, causing the base guard to lie inward and further causing the deformation of the side plate. When the side panels cannot assist and improve the depression in the base, 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, to a certain extent There are potential safety hazards for the goods, especially when the box carries fragile carriers such as beverages and milk bottles. Due to the deformation of the box base, it is easier to cause damage to the upper and lower layers during transportation or use, and when the box is reused , the frequent use of high and low temperature environment of the box is subject to large deformation and fatigue damage, which shortens the service life of the box
