Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, and in particular to a cardboard box with bottom moisture-proof function. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. They are sealed by bonding the top and bottom cardboard together. When stacked normally, the bottom is easily damaged by moisture. However, a cardboard box with bottom moisture-proof function, as described in the patent application CN 217199359 U, directly connects the moisture-proof board to the bottom of the box. This is not conducive to raising and supporting the bottom of the box, and it is easy for the lower sides to get damp and erode the inside. It has poor stability and is also not conducive to protecting the sealing area of ​​the cardboard, so the protection is not high. Therefore, we propose a cardboard box with bottom moisture-proof function. Utility Model Content

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] like Figure 1-5 As shown, this utility model is a cardboard box with a bottom moisture-proof function, including a cardboard box body 1. Top cardboard 11 is provided on both sides of the upper surface of the cardboard box body 1. It can be fixed by adhesive tape after being closed from both sides, allowing for sealing at the top for convenient protection. Bottom cardboard 12 is provided on both sides of the lower surface of the cardboard box body 1. Both sides of the bottom cardboard 12 are fixedly coated with a polyurethane moisture-proof layer 13. It can be fixed by adhesive tape after being closed from the bottom, forming a bottom for placing items. The polyurethane moisture-proof layer 13 can isolate moisture and improve the moisture-proof effect. Side support strips 14 and a middle support strip 15 are fixedly adhered to the lower surface of the bottom cardboard 12. The side support strips 14 are closer to the outer side, and the middle support strip 15 is closer to the inner side. The two bottom cardboard 12 are symmetrical on both sides, forming four support positions, resulting in high stability. This reinforces the bottom cardboard 12, improves its ability to support items, and increases the bottom height. The side support strips 14 and the middle support strips 15 are provided with transverse clearance seams 16 on their lower surfaces, which can be threaded through to bind and reinforce the carton body 1. The bottom position will not be worn, avoiding breakage, which is convenient for packaging and can form anti-slip texture, making it highly adaptable. The side support strips 14 and the middle support strips 15 are provided with reinforcement components 2 on their sides. The reinforcement components 2 include support blocks 21 and adhesive surfaces 22 for connecting support blocks 21. The adhesive surfaces 22 are fixedly attached to the upper surface of support blocks 21. The adhesive surfaces 22 are directly coated with adhesive, which can bond and fix support blocks 21, increase the connection area, improve the reinforcement effect, and ensure the stability of the bottom support, which is convenient for placement and positioning. The support blocks 21 are fixedly attached to the lower surface of the bottom cardboard 12 through the adhesive surfaces 22. The support blocks 21 are evenly distributed on the sides of the side support strips 14 and the middle support strips 15. In practical use, the bottom cardboard 12 can be closed and positioned, and then tape can be used to seal and position the seam. Then, the support blocks 21 can be aligned with the sides of the side support strips 14 and the middle support strips 15 respectively. They can be glued and fixed to enhance the structural strength and positioning stability, which can also raise the bottom height of the carton body 1. When placed, it will not directly contact the ground, avoiding ground moisture from corroding the bottom cardboard 12, improving the moisture-proof effect, and facilitating combined use. Furthermore, both the side support strip 14 and the middle support strip 15 are provided with alignment grooves 24 on their sides, and the alignment grooves 24 correspond to the positions of the support blocks 21. Furthermore, the support block 21 is provided with an alignment head 23 at its end. The alignment head 23 is inserted into the alignment groove 24. By inserting the positioning head 23 into the alignment groove 24, the support block 21 can be accurately connected. Then, it can be fixed by pasting the adhesive surface 22, which is convenient for quick installation and shaping, facilitates auxiliary support, and has high adaptability. Furthermore, the side of the middle support strip 15 is provided with a protective component 3. The protective component 3 includes a transverse slot 31 and a protective baffle 32. The protective baffle 32 is inserted between the two middle support strips 15 through the transverse slot 31. By snapping the protective baffle 32 between the two middle support strips 15, the seam of the bottom cardboard 12 can be isolated and protected, effectively reducing the entry of moisture and ensuring safety and stability. Furthermore, a clamping head 33 is fixedly connected to the inner side of the transverse slot 31. The clamping head 33 clamps the lower surface of the protective baffle 32. The clamping head 33 adopts a spherical plastic head structure. By clamping with the clamping head 33, positioning can be assisted and loosening and falling off can be prevented. Furthermore, the upper end of the protective baffle 32 is provided with an isolation surface 34, which is attached to the seam of the bottom cardboard 12. The lower end of the protective baffle 32 is provided with a push block 35. The isolation surface 34 is formed by directly coating polyurethane material onto the surface of the protective baffle 32, which can isolate moisture. Furthermore, the protective baffle 32 is provided with elastic edges 36 on both sides, and one end of the elastic edge 36 is provided with a free end 37. The elastic edge 36 presses against the inner side of the transverse groove 31. The elastic edge 36 on both sides presses against the inner side, which is conducive to auxiliary positioning, increases the frictional resistance of the surface connection, and ensures the stability of the plug-in installation. During the connection process, the protective baffle 32 can be inserted along the opening of the transverse slot 31 and pushed and connected by the push block 35. It can be installed separately between the two intermediate support bars 15, which is conducive to the connection and fixation with the bottom surface of the bottom cardboard 12. The isolation surface 34 can be attached to the seam of the bottom cardboard 12, thereby isolating and protecting, improving the moisture-proof effect, and facilitating installation and use.

[0017] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
