Description

Technical Field

[0001] The utility model relates to the technical field of display modules, and in particular to a polarizer packaging box. Background Art

[0002] Please participate Figure 1 The structure of conventional polarizer packaging box is as follows Figure 1 As shown, the box body and lid are rectangular in shape, with a storage space formed within the box body. The lid covers the top of the box body, and the outer side and bottom surfaces of the box body are both flat. The outer top surface of the lid is also flat. Polaroids are stacked and placed in the storage space of the box body, and the inner wall of the box is also provided with foam for cushioning. During transportation and storage, multiple boxes are stacked. Due to the structure of the outer surfaces of the box body and lid, the following problems arise: 1. The upper box is prone to sliding off; 2. The lid is difficult to remove from the box; 3. When multiple layers are stacked, the polaroids in the lower box will bear some of the force, resulting in risks such as crushing.

[0003] Therefore, the existing technology has defects and needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a polarizer packaging box.

[0005] The technical solution of the present invention is as follows: The present invention provides a polarizer packaging box, comprising: a box body and a box cover covering the opening above the box body, the box body comprising a rectangular bottom plate, and side panels surrounded at the four edges of the bottom plate, the side panels comprising connected side wall portions and a box body step portion, the box body step portion comprising a first step and a second step both facing the inner side of the box body, reinforcing ribs are arranged on the outer side of the side wall portion, the box cover comprises a box cover plane and box cover step portions arranged at the four edges of the box cover plane, and the formation of the box cover step portion matches the shape of the box body step portion; when the packaging boxes are stacked, the bottom plate of the packaging box on the upper layer is arranged on the box cover plane of the packaging box on the lower layer, and the side wall portion of the packaging box on the upper layer is positioned by the box cover step portion of the packaging box on the lower layer.

[0006] Furthermore, the height of the step portion of the box cover is higher than that of the step portion of the box body.

[0007] Furthermore, the reinforcing ribs are not provided at positions of the side walls close to the bottom plate. When the packaging boxes are stacked, the lower portions of the reinforcing ribs of the packaging boxes on the upper layer are positioned by the step portions of the box lids of the packaging boxes on the lower layer.

[0008] Furthermore, the box cover and the box body cooperate to form a receiving space, and cushioning foam is provided on six sides of the receiving space close to the packaging box.

[0009] By adopting the above scheme, the beneficial effects of the utility model are: the upper packaging box can be positioned by the step portion of the box cover to avoid sliding displacement; the provided reinforcing ribs can play a supporting role to avoid deformation of the lower box body and pressure on the polarizer; and it is more convenient to remove the box cover from the box body.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Please refer to Figures 2 to 4 The utility model provides a polarizer packaging box, comprising: a box body 1 and a box cover 2 covering the upper opening of the box body 1, the box body comprising a rectangular bottom plate 11, and side panels 12 surrounded at four edges of the bottom plate 11, the side panels 12 comprising connected side wall portions 121 and box body step portions 122, the box body step portions 122 comprising a first step and a second step both facing the inner side of the box body 1 and connected, wherein the upper portion is the second step and the lower portion is the first step, and reinforcing ribs 13 are provided on the outer side of the side wall portion 121, the box cover 2 comprises a box cover plane 21 and box cover step portions 22 arranged at four edges of the box cover plane 21, the formation of the box cover step portions 22 matches the shape of the box body step portions 122; when the packaging boxes are stacked, the bottom plate 11 of the packaging box on the upper layer is arranged on the box cover plane 21 of the packaging box on the lower layer, and the side wall portions 121 of the packaging box on the upper layer are positioned by the box cover step portions 22 of the packaging box on the lower layer.

[0016] Furthermore, the height of the box cover step 22 is higher than the box body step 122. When the box cover 2 needs to be removed from the box body 1, the part of the box cover step 22 that is higher than the box body step 122 can be conveniently taken to separate the box body 1 and the box cover 2.

[0017] Furthermore, the reinforcing rib 13 is not provided at the position of the side wall portion 121 close to the bottom plate 11. When the packaging boxes are stacked, the lower portion of the reinforcing rib 13 of the packaging box on the upper layer is positioned by the box cover step portion 22 of the packaging box on the lower layer. Therefore, the box cover step portion 22 of the packaging box on the lower layer can position the side wall portion 121 and the reinforcing rib 13 of the packaging box on the upper layer, thereby ensuring a good positioning effect and avoiding displacement of the packaging box on the upper layer.

[0018] Furthermore, the box cover 2 and the box body 1 cooperate to form a receiving space, and cushioning foam is provided on the six sides of the receiving space close to the packaging box, which can provide a cushioning effect for the placed polarizer and achieve better effect.

[0019] In this solution, the box body 1 and the box cover 2 can both be made of PET, and the box body 1 and the box cover 2 can both be integrally formed by a blister forming process.

[0020] In summary, the beneficial effects of this solution are: the upper packaging box can be positioned by the step portion of the box cover to avoid sliding displacement; the provided reinforcing ribs can play a supporting role to prevent the lower box body from deforming and causing pressure on the polarizer; and it is more convenient to remove the box cover from the box body.

[0021] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
