Description

Technical Field

[0001] The utility model relates to the technical field of paper boxes, in particular to a leak-proof corrugated paper box for packaging. Background Art

[0002] Corrugated boxes are the most widely used packaging products, and their usage has always been the highest among all packaging products, including calcium plastic corrugated boxes. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers with their superior performance and good processing properties.

[0003] Traditional packaging cartons are an indispensable part of modern logistics. They play the role of containment and protection, and the requirements for cartons are constantly increasing. Most traditional cartons are made directly of corrugated cardboard. This leads to liquid leakage inside the carton. The liquid damages the structure of the carton material and affects the movement and handling, thus causing economic losses. To address the above problems, we propose a leak-proof corrugated carton for packaging. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A leak-proof corrugated paper box for packaging includes a box body 1 and an upper cover 14. The box body 1 is provided with a rotating groove 2, and a rotating ring 4 is rotatably provided in the rotating groove 2. The box body 1 and the rotating ring 4 are respectively provided with a plurality of ventilation holes 3 and matching holes 5. The number of the ventilation holes 3 and the matching holes 5 are twelve, and the ventilation holes 3 and the matching holes 5 are evenly spaced in the circumferential direction. As shown in the figure, the aperture sizes of the ventilation holes 3 and the matching holes 5 are the same. When the ventilation holes 3 and the matching holes 5 coincide with each other, ventilation and air exchange operations of the items placed in the box body 1 can be realized.

[0022] A positioning rod 15 is installed on the bottom wall of the upper cover 14, and a collecting groove 8 is provided on the bottom wall of the box body 1, and a waterproof groove 9 is provided in the collecting groove 8. A drainage hole 10 is provided on the collecting groove 8 and the box body 1, and a sealing plug 11 is provided in the drainage hole 10. The surface of the waterproof groove 9 has a waterproof coating, and the liquid flowing into the collecting groove 8 will accumulate on the waterproof groove 9, thereby effectively preventing leakage from polluting the environment or causing damage to the box body 1. The sealing plug 11 can be pulled out to realize the falling and collection operation of the above-mentioned liquid. As shown in the figure, the inner walls on both sides of the collecting groove 8 and the waterproof groove 9 are inclined to facilitate the final convergence in the waterproof groove 9.

[0023] The rotating ring 4 and the box body 1 are both provided with a first positioning groove 6 corresponding to the positioning rod 15, and a second positioning groove 7 is provided near each first positioning groove 6 on the rotating ring 4. When the ventilation hole 3 coincides with the matching hole 5, the first positioning groove 6 on the rotating ring 4 and the box body 1 are combined to form a circle. Correspondingly, when the ventilation hole 3 and the matching hole 5 are staggered, the second positioning groove 7 on the rotating ring 4 corresponds to the first positioning groove 6 on the box body 1.

[0024] The first positioning groove 6 is arranged corresponding to the ventilation hole 3, and the second positioning groove 7 is located between the two matching holes 5. Since there are twelve ventilation holes 3 and matching holes 5 in this scheme, the rotating ring 4 can rotate 30 degrees relative to the box body 1 to achieve the overlap of the ventilation hole 3 and the matching hole 5, and rotate 15 degrees to achieve the staggered arrangement of the two, and each matching hole 5 is located in the middle of the two ventilation holes 3.

[0025] A plurality of inner bearing blocks 12 are provided on the inner bottom wall of the box body 1, and a plurality of outer bearing blocks 13 are provided on the inner side wall of the box body 1. The inner bearing blocks 12 and the outer bearing blocks 13 make up for the hole gaps of the collecting groove 8, ensuring the contact area so that the items placed in the box body 1 are well supported.

[0026] A folding plate 16 is installed on the bottom wall of the upper cover 14, and a gripping rod 18 is also provided on the upper cover 14. The folding plate 16 is elastic, which realizes the pressing operation of putting materials into the box body 1, and the upper cover 14 can be stably covered on the box body 1 by any means of the existing technology and is easy to open and disassemble.

[0027] A hidden groove 17 is provided on the outer surface of the upper cover 14, and a gripping rod 18 is arranged in the hidden groove 17. After the palm enters the hidden groove 17 and grips the gripping rod 18, the upper cover 14 can be conveniently lifted to facilitate the opening of the box body 1. Compared with the exposed setting, its hidden setting is more convenient for stacking and use.

[0028] When the utility model is used, articles are put into the box body 1, and the articles are effectively supported by the inner bottom wall of the box body 1, the inner bearing blocks 12 on the inner bottom wall, and the outer bearing blocks 13 on the inner side walls. After the upper cover 14 is covered, the folding plate 16 presses down the articles to ensure their stability in the box body 1, and then the upper cover 14 can be fixed by relying on the existing technology.

[0029] If the item does not need ventilation, the rotating ring 4 rotates in the rotating groove 2, and the first positioning groove 6 on the rotating ring 4 corresponds to the first positioning groove 6 on the box body 1. At this time, the ventilation hole 3 is staggered with the matching hole 5. At this time, the positioning rod 15 on the upper cover 14 is inserted into the above-mentioned first positioning groove 6. Since the upper cover 14 is fixed and cannot rotate relative to the box body 1, the rotating ring 4 cannot rotate in the rotating groove 2 either.

[0030] If the items need to be ventilated, the rotating ring 4 rotates in the rotating groove 2, and the second positioning groove 7 on the rotating ring 4 corresponds to the first positioning groove 6 on the box body 1. At this time, the ventilation hole 3 coincides with the matching hole 5. At this time, the positioning rod 15 on the upper cover 14 is inserted into the above-mentioned first positioning groove 6 and the second positioning groove 7. Since the upper cover 14 is fixed and cannot rotate relative to the box body 1, the rotating ring 4 cannot rotate in the rotating groove 2 either. The ventilation of the items in the box body 1 can be achieved with the help of the ventilation hole 3 and the matching hole 5.

[0031] If liquid leaks from the box 1, it will slide down the inclined inner wall of the collecting groove 8 into the waterproof groove 9 and be collected by the waterproof groove 9 to prevent pollution and damage to the box 1 caused by leakage. To collect the above liquid, you only need to pull out the sealing plug 11 and let it fall from the waterproof groove 9.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
