Description

Technical Field

[0001] The utility model relates to the technical field of cartons, in particular to a high-pressure-resistant carton. Background Art

[0002] Currently, large-volume injection products are commonly packaged in 3-layer or 5-layer corrugated cartons. Due to the carton structure and cost issues, attention should be paid to issues such as environmental humidity, carton paper matching, stacking method, and stacking height during product storage and use. The compressive strength of ordinary corrugated cartons drops sharply after getting damp, and the large-volume injections contained in the carton need to bear greater pressure after the carton's pressure resistance drops, causing the product to deform or even break. Utility Model Content

[0003] In order to make up for the deficiencies in the prior art, the utility model provides a high-compression-resistant carton, which adopts a multi-point support structure and can effectively improve the compressive strength, so that the carton can remain basically unchanged after long-term stacking, preventing the products in the box from being damaged due to the deformation of the carton.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A high-pressure-resistant carton comprises an outer cardboard and an inner supporting cardboard, wherein the inner supporting cardboard is H-shaped and the four ends of the H-shape are provided with inward-turned folded edges, the outer cardboard surrounds the opening of the inner supporting cardboard, the outer cardboard is provided with outward-turned folded edges bonded to the corresponding side edges of the inner supporting cardboard, and the inward-turned folded edges are bonded to the outer cardboard.

[0006] Furthermore, the inner supporting paperboard is formed by detachably connecting two side panels and a middle panel.

[0007] Furthermore, a middle slot is provided in the middle of the side plate, and side slots are provided on both sides of the middle plate, and the side slots are plugged into the middle slot.

[0008] Furthermore, the outer paperboard is provided with a left top cover area, a left side panel area, a bottom panel area, a right side panel area and a right top cover area from left to right, and a crease line is provided at the junction of adjacent areas.

[0009] Furthermore, the outwardly turned folded edge corner is chamfered.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects:

[0011] The high-compression-resistant carton of the utility model adopts a multi-point support structure. The four corners increase the thickness and supporting force through the combined effect of the inward folding edges and the outward folding edges compared to ordinary cartons. The center then increases the line contact supporting force through the H-shaped structure, thereby improving the overall compressive strength of the carton. Tested compressive strength can reach more than 5000N, and the protection effect on the products is far superior to cartons with ordinary structures. The carton has basically no deformation after long-term stacking, and can effectively prevent the products in the box from being damaged due to deformation of the carton.

[0015] Many specific details are described in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from the description, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Example 1

[0017] like Figure 1 , 2 As shown, a high-pressure-resistant carton includes a split peripheral paperboard 1 and an inner supporting paperboard 2. The peripheral paperboard 1 is in a long strip shape, and is provided with a left top cover area 11, a left side panel area 12, a bottom panel area 13, a right side panel area 14 and a right top cover area 15 from left to right, and a crease line 16 is provided at the junction of adjacent areas. Both sides of each area of ​​the peripheral paperboard 1 are provided with an outward folding edge 17, and the corner ends of the outward folding edge 17 are chamfered.

[0018] The inner support paperboard 2 is H-shaped, which can be an integrally formed structure or a spliced ​​formed structure. In this embodiment, the spliced ​​formed structure is preferred. Specifically, the inner support paperboard 2 is composed of two side panels 21 and a middle panel 22. A middle slot 211 is provided in the middle of the side panel 21, and side slots 221 are provided on both sides of the middle panel 22. The middle panel 22 is inserted into the middle slot 211 of the side panel 21 through the side slots 221. Inward folding edges 212 are provided on both sides of the side panel 21.

[0019] The use process of the utility model is as follows: firstly, the outer cardboard 1 is laid flat on the table, and then the bottom opening of the inner supporting cardboard 2 is placed on the bottom plate area 13 of the outer cardboard 1, and the outward folded edge 17 of the bottom plate area 13 is pasted on the outer side of the side plate 21; then, the outer cardboard 1 is bent, so that the left side plate area 12 is fitted with the left opening of the inner supporting cardboard 2, and the right side plate area 13 is fitted with the right opening of the inner supporting cardboard 2, and then the left side plate area 12 and the right side plate area 13 are pasted with the inward folded edges 212 of the corresponding sides, and the outward folded edges 17 of the left side plate area 12 and the right side plate area 13 are pasted on the outer side of the side plate 21, so as to form a box body with two chambers; after the box body is filled with materials, the left top cover area 11 and the right top cover area 15 are buckled on the top opening of the inner supporting cardboard 2, and the outward folded edges 17 of these areas are pasted with the outer side of the side plate 21, so as to complete the boxing.

[0020] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
