Description

Technical Field

[0001] The utility model relates to the technical field of paper packaging, in particular to a packaging paper tube which is anti-deformation and durable in use. Background Art

[0002] A paper tube is a tubular object made of paper, mainly used for packaging, transporting and storing various items. Most paper tubes are spiral paper tubes and seamless paper tubes. Because the material of paper tubes is relatively soft, they are easily dented after impact, which affects their use.

[0003] Based on the above problems, the existing patent with publication number CN216763906U discloses a deformation-resistant and durable paper tube. The paper tube relies on a support structure layer to improve the hardness and strength of the paper tube. At the same time, by providing an anti-corrosion layer, its moisture resistance can be improved, and it has a certain survival ability in a humid environment. At the same time, the center can be supported by the support structure during transportation to avoid depression due to extrusion.

[0004] However, when implementing the above-mentioned anti-deformation durable paper tube, it was found that there were at least the following problems. When the paper tube is stacked, pressed or knocked against the corner of the table during daily transportation, the outer wall of the paper tube is easily depressed by the force, and a dent is generally left on the outer wall of the paper tube. It is difficult to restore and affects the appearance of the paper tube. Moreover, when the paper tube is used for support, the paper tube is easily folded or bent along the dent, reducing the supporting force of the paper tube. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example: See Figures 1 to 4 According to an embodiment of the present invention, a technical solution is provided: a deformation-resistant and durable packaging paper tube, a paper tube body formed by composite winding, which includes an outer tube body 31 and an inner tube body 32; multiple first reset sheets 1, every two first reset sheets 1 are connected end to end and fixed, the first reset sheet 1 has two supporting ends one and an arc surface end one, the arc surface end one is against and fixed to the outer tube body 31, and the two supporting ends one are against and fixed to the inner tube body 32; multiple second reset sheets 2, every two second reset sheets 2 are connected end to end and fixed, the second reset sheet 2 has two supporting ends two and an arc surface end two, the arc surface end two is against and fixed to the inner tube body 32, and the two supporting ends two are against and fixed to the outer tube body 31; the first reset sheet 1 and the second reset sheet 2 are cross-fixed, and a force-bearing gap 4 is provided between the arc surface end one and the arc surface end two.

[0026] The above-mentioned structure is used for anti-deformation and a durable packaging paper tube is used. When the packaging paper tube is squeezed, the first reset piece 1 is forced to shrink downward, and because the second reset piece 2 is fixed to the first reset piece 1, part of the squeezing force can be absorbed, thereby reducing the influence of the squeezing force on the packaging paper tube. After being subjected to force, the first reset piece 1 and the second reset piece 2 can rebound, thereby maintaining the beauty of the outer wall of the packaging paper tube and preventing dents from appearing on the outer wall of the packaging paper tube. This solves the problem in traditional technology that after the outer wall of the paper tube is depressed by force, dents are generally left on the outer wall of the paper tube, which is difficult to restore and affects the beauty of the paper tube. In addition, when the paper tube is used for support, it is easy to fold or bend along the dent, thereby reducing the supporting force of the paper tube.

[0027] In this embodiment, in order to reduce production costs and increase the resilience of the first reset plate 1 and the second reset plate 2, the material of the first reset plate 1 and the second reset plate 2 is set to plastic. While reducing production costs, the plastic itself has a good rebound effect and is lightweight, thereby increasing its support and reset effect on the packaging paper tube.

[0028] In this embodiment, in order to prevent the support end 1 of the first reset plate 1 and the support end 2 of the second reset plate 2 from causing damage to the outer tube body 31 and the inner tube body 32 during the force application process, support plates 5 are fixed at the end where the first reset plate 1 and the second reset plate 2 are connected. The support plates 5 located between the first reset plates 1 are fixed to the outer tube body 31, and the support plates 5 located between the second reset plates 2 are fixed to the inner tube body 32, so that the support plates 5 are in contact with the outer tube body 31 and the inner tube body 32, thereby reducing the damage to the outer tube body 31 and the inner tube body 32 caused by the support end 1 and the support end 2.

[0029] In this embodiment, in order to ensure the strength and durability of the paper tube body 3, the outer tube body 31 and the inner tube body 32 are both made of kraft paper. Kraft paper is relatively thick and has high strength and durability, and is suitable for supporting and protecting the paper tube body 3.

[0030] In this embodiment, when drying and stacking the paper tube body 3, the paper tube body 3 generally needs to be hung vertically for drying or stacked vertically. During the stacking or drying process, the opening of the paper tube body 3 is often depressed inward by force. When supporting it later, it is difficult to directly insert the tool along the opening of the paper tube body 3. After the depression, the paper tube body 3 is prone to stratification. If it is stored in a relatively humid place, moisture can easily enter the paper tube body 3 from the delamination, affecting the paper tube body 3. Therefore, both ends of the opening of the paper tube body 3 are provided with tapered vertical support members 6. The support member 6 has a first end with a smaller inner diameter and a second end with a larger inner diameter. The first end can be inserted into the inner tube body 32, and the outer wall of the second end can be against the inner wall of the inner tube body 32. A limit block extends outward from the opening of the second end. When the support member 6 is placed vertically on the inner wall of the inner tube body 32, the limit block is against the opening of the paper tube body 3. The inner wall of the inner tube body 32 is supported by the vertical support member 6 to prevent the paper tube body 3 from sinking, and the opening of the paper tube body 3 is covered by the limit block. When stacked vertically, the limit block can be supported against the ground to reduce moisture and wear of the paper tube body 3.

[0031] In this embodiment, in order to prevent the vertical support member 6 from being subjected to a large force, thereby causing a dent to affect the paper tube body 3, a cross-arranged support rod 7 is provided at the second end of the vertical support member 6, so that both ends of the support rod 7 are fixed to the vertical support member 6, and the vertical support member 6 is supported by the support rod 7 to prevent it from being dented.

[0032] Working Principle: When the packaging paper tube is squeezed, the first reset piece 1 contracts downward under the force, and because the second reset piece 2 is fixed to the first reset piece 1, it can absorb part of the squeezing force, reducing the impact of the squeezing force on the packaging paper tube. After the force is applied, the first reset piece 1 and the second reset piece 2 can rebound, maintaining the beauty of the outer wall of the packaging paper tube and preventing dents on the outer wall of the packaging paper tube;

[0033] When drying and stacking the packaging paper tubes, the vertical support 6 can be inserted into the inner wall of the inner tube body 32 to support the inner tube body 32 to prevent the paper tube body 3 from sinking, and the opening of the paper tube body 3 can be covered by the limit block. When stacking vertically, the limit block can be supported by the ground to reduce moisture and wear of the paper tube body 3.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
