It uses plastic (non-paper) material as substrate to change the structure of original plastic material fixed box body. The side surfaces and the bottom surface (or other surfaces) of the box body are linked by movable joints, so that all the side surfaces can be freely folded inwards under an unconstrained condition. When the box body is loaded, the side panels can be firmly vertical to the bottom surface under the restraint of the ectopic barbs and the tenon lock catches, and the use is not different from the fixed box body. When no-load, as long as contact heterotopia barb and the restraint of drill bit hasp, just can conveniently fold in, make the side board closely knit the stack in order on the bottom panel, reduce the space and occupy, be of value to the reuse of thing flow box, be of value to "green commodity circulation".)

1. The utility model provides a production and operation of formula commodity circulation case that can superpose used repeatedly of infolding, it is one kind and changes fixed connection of fixed side board and bottom panel of box into swing joint, makes the box that the contained angle can be changed to the bottom panel to the side board. When the side panel is restrained by the ectopic barb and the tenon lock catch, the included angle between the side panel and the bottom panel is 90 degrees; when the restraint is relaxed, the bottom panel and the side panel can be in a parallel shape or tend to be in a parallel shape, and the logistics box can be compactly and compactly folded.

2. The connection between the side panels is fixed by the tenon lock catch, and the tenon lock catch utilizes the elasticity of the material to prevent the side panels from easily moving (see figure 8 in detail).

3. The ectopic barb is used in the logistics box, so that the longitudinal bearing force and the lifting force of the side panel can be enhanced, the side panel can be restrained from inclining inwards, and the state of being vertical to the bottom panel is kept.

4. The movable relation of the connection of the bottom panel and the side panel in the box adopts a special structure of oblique insertion and vertical use, namely, the box is obliquely inserted and installed during installation, and after the box is rotated for a certain angle, the side panel is perpendicular to the bottom panel and then stressed, so that the bearing area can be enlarged, namely, the movable joint can be smaller under the condition of certain stress (detailed figures are 7-5-1 and 7-6-1).

5. After the box is stacked in an empty state, the box is still in a complete and integrated shape, no additional accessory is added, and the box can be stabilized only by using the existing bayonet. If the box cover is needed, see fig. 6, and if the box cover is not needed, see fig. 5, the box cover is flexible and convenient.

The technical field is as follows:

in recent years, with the rapid development of the logistics field, the usage amount of the logistics boxes is increased day by day, which causes the synchronous improvement of garbage and the waste of a large amount of resources. Therefore, the people have proposed "green logistics" and "recycling economy" advocating that logistics packages can achieve "reduction, reuse, recycling". However, because of the material and structure of the traditional logistics packaging box, the reduction and reuse are still in the advocated stage and are difficult to implement. Some of the scattered and non-packaged articles like fruits and vegetables lack reusable and foldable packaging logistics boxes.

The invention provides an inward folding type foldable reusable novel logistics box (box) in the field of logistics, which can be folded inwards, so that the occupied space during no-load (no-load refers to the condition that no articles are contained in a packaging box) is greatly reduced, and the novel logistics box is more convenient to reuse.

Background art:

the traditional paper packaging box (corrugated paper carton) is difficult to reduce and reuse due to poor durability, easy stain, difficult cleaning and the need of a large amount of adhesive tapes for matching use. At present, although a large amount of recycling is carried out on the cartons, a large amount of resource and energy are still wasted. The presence of plastic logistics boxes, while overcoming various drawbacks of the cartons, is not structurally advantageous. For example, the appearance of the current plastic logistics box mainly comprises a fixed cuboid and a table hexahedron. Because of the fixed cuboid, the box also occupies the same appearance space regardless of whether the box is filled with articles or not, so that the recycling cost is high; although the table hexahedron can be stacked when in no-load state and part of space when in no-load state is compressed, any side surface of the table is not perpendicular to the bottom surface due to the limitation of table shape, longitudinal stress and stacking height are affected, and the upper bottom and the lower bottom of the table type packaging box have different areas and different side lengths, and can be used only by being covered with a cover when being stacked, so that the stacking height not only needs to enhance the thickness of the side surface of the box body, but also needs to enhance the thickness of the side surface of

The invention content is as follows:

based on plastic materials (non-low-quality materials), the invention (but not limited to plastic raw materials, and the search for renewable materials which are more durable, more pressure-resistant, easier to clean and lighter in weight still works in the direction of 'reduction and reuse'), the structure of a fixed box body of a traditional cuboid (hexahedron) is reformed, four side surfaces of the box body are hinged relative to a bottom surface (or other surfaces) by movable joints, the box body can be rotated and folded, a pair of side surface ectopic barbs are attached, and four pairs of tenon type lock catches are matched between every two side surfaces. When the commodity circulation case was unloaded, dystopy barb and four hasps all were in lax (not atress) state, and each side can freely internal deflection rotate to fold together with bottom surface (or other faces), form the whole that reduces, greatly reduced occupation space, the space that makes "reuse" in-process recovery, storage transportation reduces, thereby practices thrift the cost. When the logistics box is used (loaded), the ectopic barbs on the pair of side surfaces are tightly supported, so that the longitudinal bearing force and the lifting stress of the logistics box are enhanced, the inward inclination of the side surfaces is effectively limited, then the four side surface connecting positions are respectively buckled by the four tenon type lock catches, and under the action of the one-way function of the lock catches and the corresponding limiting baffle plates, the movement of the side plates is limited, so that the side plates are firmly perpendicular to the bottom surface (or other surfaces) and the fixed logistics box is not different from the fixed logistics box when the side plates are used, which is the main content of the invention.

The details are as follows: 1, upper cover (1 piece) indicated by the number in fig. 2; 2. a movable snap ring (4 pieces) of the tenon lock catch; 3. flexible tenons (4 pieces) of the tenon lock catch; 4. an upper cover buckle ring (2 pieces); 5. long side panels (2 pieces); 6. bottom panel (1 piece); 7. ectopic barbs (2 pieces); 8. short side panels (2 pieces). Instructions for use: FIG. 1 is a perspective view of the loading (application) state of the material flow box, which is shown in FIG. 2 after the material flow box is applied and the upper cover is opened to take out the contents; as shown by the arrow in fig. 2, the tenon lock catch is firstly released, and then the short side panel is turned outwards to be in the shape shown in fig. 3; turning the long side panel inwards as shown by the arrow in fig. 3, breaking the upper cover buckle and turning the short side panel outwards as shown by the arrow in the figure, and forming a shape of fig. 4; then, according to the arrow in fig. 4, the inward-folded short side panels, the inward-folded ectopic barbs and the upper cover plate are in the shape of fig. 5; finally, the upper cover is pressed downwards according to the arrow direction of fig. 5, so that the upper cover plate is buckled on the movable joint of the short side panel, and the state of fig. 6 is formed. That is, fig. 1 is the load (use) state of the logistics box, fig. 6 is the inner folding state of the logistics box when the logistics box is in no-load state, the no-load space is greatly reduced, and the side panel cannot move and bounce due to the constraint of the ectopic barb and the tenon lock catch when the logistics box is in use (fig. 1), and the situation is the same as that of the fixed box. The present sequence is transferred from the active state to the unloaded state, i.e. from fig. 1 to fig. 6. From the idle state to the active state, the sequence from fig. 6 to fig. 1 is in order and the directions of the operation arrows are reversed. If the occasion that does not need the upper cover: for example, the upper cover plate can be removed when transporting fruits and vegetables, and the box body can be hollowed or sealed according to the use requirement from fig. 2 to fig. 5. FIG. 7 (FIGS. 7-1, 7-2, 7-3, 7-4, 7-5-1, 7-6-1, 7-7, and 7-8) is a view of each component to be explained, and FIG. 8 is a working principle diagram of the tenon lock catch, i.e. 1, before the two side plates are embedded, the tenon is close to the base of the buckle, so that the tenon is forced outwards; 2. when the tenon is embedded into the retaining ring, the elasticity is recovered, so that the tenon is blocked in front of the retaining ring base; 3. when the retaining ring is rotated to buckle the tenon, the front part of the tenon is slightly larger, and the tenon is pressed inwards; 4. when the retaining ring enters the fixing position, the tenon is removed by external force and the original shape is recovered, and the tenon protrudes from the two sides and is respectively clamped by the retaining ring and the base and cannot be flicked.

The specific implementation scheme is as follows:

the invention is suitable for the packaging of various articles in the logistics process, can replace all the existing logistics boxes, and has the advantages that the logistics boxes can be folded into a whole when no load exists, thereby greatly reducing the use space, being convenient for recovery, storage and transportation and being beneficial to reuse. If can rent the use, will reduce the consumption of present packing box by necessity, realize green commodity circulation.
