Technical Field
[0001] This utility model relates to the field of cardboard box technology, specifically to a cardboard box that is not easily deformed by pressure. Background Technology
[0002] Cardboard boxes are the most widely used packaging products, usually made of corrugated cardboard or hardboard. These materials provide a certain level of protection while being relatively lightweight, easy to process, and recyclable.
[0003] Cardboard boxes are often stacked after packaging goods, requiring them to have a certain level of compression resistance, meaning they shouldn't easily deform under pressure to provide good protection for the contents. Currently, the most common method to improve the compression resistance of cardboard boxes is to secure the cardboard tubes to the corners by nailing or gluing. However, this method is not only time-consuming and labor-intensive, but also requires additional equipment for processing the cardboard tubes and securing them to the box, increasing costs.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-2This utility model provides a technical solution: a cardboard box that is not easily deformed by pressure, comprising four vertical plates 1 connected in sequence, an upper folding plate 2 connected to the top of the vertical plate 1, a lower folding plate 3 connected to the bottom of the vertical plate 1, and a connecting part 4 connected to the outside of one of the end vertical plates 1. The vertical plate 1 and the upper folding plate 2 and the lower folding plate 3 are respectively provided with upper folding crease 2.1 and lower folding crease 3.1.
[0020] The connecting part 4 is folded into a prismatic shell structure. The connecting part 4 includes a central strip 4.1 and adhesive strips 4.2 connecting both sides of the central strip 4.1. The inner adhesive strip 4.2 is connected to the corresponding upright plate 1, and is bonded to the edge of the inner wall of the corresponding upright plate 1. The width of the central strip 4.1 is [missing information - likely a percentage] of the width of the adhesive strip 4.2. The middle strip 4.1 has an outer fold 4.02 between it and the two side adhesive strips 4.2, and the adhesive strip 4.2 has an inner fold 4.01 between it and the corresponding upright plate 1. That is, by folding the outer fold 4.02 outward and the inner fold 4.01 inward, the connecting part 4 is folded into a triangular prism shell structure with an isosceles right triangle cross section. By bonding the adhesive strip 4.2 to the inner sidewall edge of the corresponding upright plate 1, the triangular prism shell structure is firmly connected to the upright plate 1 to form a stable corner support structure.
[0021] A support portion 5 is folded between two adjacent upright plates 1. The support portion 5 has a prismatic shell structure. The support portion 5 includes a central slat 5.1 and an adhesive slat 5.2 connecting the central slat 5.1 and the upright plate 1. The adhesive slat 5.2 is adhered to the edge of the corresponding inner wall of the upright plate 1. The width of the central slat 5.1 is [missing information - likely a percentage] of the width of the adhesive slat 5.2. The middle strip 5.1 has an outer fold 5.02 between it and the two adhesive strips 5.2 on both sides, and the adhesive strip 5.2 has an inner fold 5.01 between it and the corresponding upright plate 1. That is, by folding the outer fold 5.02 outward and the inner fold 5.01 inward, the support part 5 is folded into a triangular prism shell structure with an isosceles right triangle cross section. By bonding the adhesive strip 5.2 to the inner sidewall edge of the corresponding upright plate 1, the triangular prism shell structure is firmly connected to the upright plate 1 to form a stable corner support structure.
[0022] In summary, triangular prism shell structures are formed at the four corners of the carton's interior cavity, thereby enhancing the carton's compression resistance and ensuring it is not easily deformed under pressure. Furthermore, after adhesive strips 4.2 and 5.2 are attached and glued to the inner wall of the upright plate 1, the two sides of the middle strips 4.1 and 5.1 are respectively attached to the inner wall of the upright plate 1, forming a chamfered structure at the carton's internal corners. This ensures the carton's interior cavity is regularly sized, facilitating the sealing of items.
