Description

Technical Field

[0001] The utility model belongs to the technical field of boxes and relates to a foam box. Background Art

[0002] When engine parts need to be transported and stored, foam boxes are usually used for transportation and storage to reduce shock during transportation and storage of engine parts. However, during transportation, multiple foam boxes usually need to be stacked, resulting in the foam boxes having a higher load-bearing capacity.

[0003] For example, Chinese patent application [application publication number: CN115593787A] discloses a high load-bearing turnover foam packaging box, which is made of hard foam. The packaging box includes a box body and a cover body. The inner side of the edge of the box opening of the box body is provided with a covering protrusion, the inner side surface of the cover body is provided with a covering groove matching the covering protrusion, the outer side surface of the cover body is provided with a overlapping protrusion, and the bottom of the box body is provided with an overlapping groove. The outer edge of the overlapping protrusion, the outer edge of the overlapping groove, and the outer edge of the covering protrusion coincide with the orthographic projection of the horizontal plane.

[0004] The above structure is achieved by making the packaging box out of hard foam, and in order to improve the load-bearing capacity of the packaging box, a reinforcing rib structure is added inside the box, and the stacking stability is improved by setting overlapping protrusions and overlapping grooves, and the structural strength of the entire box is also improved. However, in actual use, when multiple boxes are stacked together, the bottom few boxes will still be subjected to heavier pressure, causing the box to still deform after being squeezed, and because the entire box cannot provide a large deformation space, the box is easily broken after being squeezed, affecting the specific use of the foam box. Utility Model Content

[0005] The purpose of the utility model is to propose a foam box in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is: how to solve the problem that the prior foam box is easily squeezed and broken after being squeezed.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A foam box comprises an upper box body and a lower box body, wherein a plurality of corresponding partitions are arranged in the upper box body and the lower box body, and the character is that a plurality of circumferentially distributed clearance notches are provided on the lower edge of the upper box body, and the clearance notches are all concave upwards, and downwardly concave deformation grooves are provided on the left and right ends of the upper edge of the upper box body, and the deformation groove is arranged in correspondence with one of the clearance notches, and the clearance notch corresponding to the deformation groove is located within the projection range of the deformation groove.

[0008] Working principle: Place the parts to be stored in the space formed by the partition, the upper box body or the enclosure of the upper box body, and the space formed by the enclosure of the partition itself. Then cover the upper box body and the lower box body to achieve the storage of the parts. There are deformation grooves opened at both the left and right ends of the upper edge of the upper box body. The deformation grooves are recessed downward, and there are a plurality of first relief notches opened circumferentially along the upper edge of the lower edge of the upper box body. By setting the deformation groove corresponding to one of the first relief notches up and down, when the foam boxes are stacked, the upper box body of the foam box is subjected to a relatively large bearing pressure. By opening the deformation groove, after being squeezed, the deformation of the upper end of the upper box body can be directed towards the deformation groove. The upper box body has a certain deformation space, and when deforming, under the setting of the deformation groove, the upper end of the upper box body deforms in the direction of the deformation groove, resulting in the lower end of the upper box body also deforming in the direction of the deformation groove. Therefore, setting the two first relief notches corresponding to the deformation groove up and down facilitates providing a certain deformation space after the lower end of the upper box body deforms. And in order to ensure the abutting stability of the upper box body and the lower box body, the above structure adopts the setting of opening the deformation groove and the first relief notch, so that the upper box body can quickly provide a deformation space when being squeezed, avoiding its extrusion and rupture, and does not affect the abutment of the upper box body and the lower box body. When ensuring there is enough deformation space, it can also improve the supporting force of the lower end of the upper box body as much as possible. The first relief notch can also be used for the fingers to be inserted when opening the box, facilitating the opening of the upper box body and the lower box body. And by opening grooves or openings, the production materials of the upper box body are reduced, saving its production cost.

[0009] For the partition in this application, it can be set to follow the parts to be placed.

[0010] In the above-mentioned foam box, the two deformation grooves are symmetrically arranged left and right along the center line of the upper box body.

[0011] The setting of this structure enables the upper box body to deform quickly along the direction of the two deformation grooves after being squeezed, having a certain symmetry and improving the stability of the upper box body after deformation.

[0012] In the above-mentioned foam box, the upper edge of the lower box body is provided with second relief notches corresponding to the first relief notches one by one. The second relief notches are all recessed downward. The opening of the first relief notch faces downward, and the opening of the second relief notch faces upward. The first relief notch and the corresponding second relief notch enclose a through hole in a circular or strip shape.

[0013] The setting of the second relief notch, on the one hand, encloses a through hole with the corresponding first relief notch, facilitating the user's fingers to pass through more quickly. On the other hand, when the bearing pressure of the upper box body is relatively large, the upper end of the lower box body can also have a deformation space, further improving the bearing capacity of the foam box and also enhancing the stability and convenience of use.

[0014] In the above-mentioned foam box, the first clearance gap passes through the upper box body in the horizontal direction, and the second clearance gap passes through the lower box body in the horizontal direction.

[0015] The setting of the first and second clearance gaps makes it easier for the user's fingers to pass through, so that the user can apply better force when opening the upper box body, thereby improving the convenience of using the foam box.

[0016] In the above-mentioned foam box, the corners of the lower bottom wall of the deformation groove have rounded chamfers.

[0017] The setting of the rounded corners improves the ability of the upper end of the upper box body to be squeezed along the rounded corners after being subjected to force, and also facilitates the resetting of the upper box body, thereby improving the stability of the foam box in use.

[0018] In the above-mentioned foam box, at least one reinforcing rib is provided on the bottom wall of the upper box body and the bottom wall of the lower box body.

[0019] The provision of reinforcing ribs further strengthens the structural strength of the upper box body and the lower box body.

[0020] Compared with the prior art, the foam box has the following advantages: the structure is provided with a deformation groove and a clearance notch, so that the upper box body can quickly provide deformation space when squeezed to avoid its squeezing and rupture, and it does not affect the abutment between the upper box body and the lower box body. While ensuring that there is sufficient deformation space, the supporting force of the lower end of the upper box body can be increased as much as possible, and the clearance notch can also be used as a finger to be inserted when opening the box, which facilitates the opening of the upper box body and the lower box body, and by providing a groove or a mouth, the production materials of the upper box body are reduced, saving its production cost.

[0031] like Figures 1 - 4As shown, two deformation grooves 12 are symmetrically arranged on the left and right along the center line of the upper box body 1. The width of the deformation groove 12 is greater than the width of the corresponding first relief notch 11.
