Description

Technical Field

[0001] The utility model relates to the technical field of paper tube structures, in particular to a novel compression-resistant and waterproof paper tube. Background Art

[0002] A paper tube refers to a tubular object processed from paper, which is widely used for the bearing and packaging of various films and can also be used for the protective packaging of items. However, the existing paper tubes are formed by winding paper. When fragile items are placed inside the paper tube, the weight of the paper tube itself will increase. When the paper tubes are stacked and transported in large quantities, it is easy for the paper tubes to be squeezed against each other, causing them to deform and bend, resulting in damage to the packaged items. For this reason, we propose a novel compression-resistant and waterproof paper tube. Content of the Utility Model

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a novel compression-resistant and waterproof paper tube.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme. A novel compression-resistant and waterproof paper tube includes a supporting inner sleeve and end supporting sleeves sleeved and installed at both ends of the supporting inner sleeve. A group of protective air bags with air pressure inside are sleeved and wrapped outside the supporting inner sleeve. An assembly groove is formed on the periphery of the end supporting sleeve, and a group of elastic sheets are arranged inside the assembly groove. A paper tube structure is formed by winding outside the end supporting sleeve, and sealing covers capable of sealing and protecting the ends of the paper tube structure are arranged at both ends of the supporting inner sleeve.

[0005] Preferably, the periphery of the protective air bag and the elastic sheet are in mutual support and fitting, and the side of the elastic sheet corresponding to the paper tube structure and the inner side of the paper tube structure are in mutual support and fitting.

[0006] Preferably, when the outside of the paper tube structure is compressed, the paper tube structure is in a supporting and buffering state through the elastic sheet. When the paper tube structure squeezes the protective air bag through the elastic sheet, the protective air bag is in a supporting and buffering state against the elastic sheet.

[0007] Preferably, one end of the sealing cover is integrally formed with a connecting end, and fitting threads that match each other are formed on the periphery of the connecting end and a partial position on the inner side of the supporting inner sleeve. The sealing cover is in threaded connection and cooperation with the inner side of the supporting inner sleeve through the fitting threads on the periphery of the connecting end.

[0008] Preferably, polyethylene film layers are arranged on the inner side of the supporting inner sleeve and the periphery of the paper tube structure, and the polyethylene film layer itself has waterproof properties.

[0009] The utility model provides a novel compression-resistant and waterproof paper tube. It has the following beneficial effects:

[0010] 1. For this new type of compression-resistant and waterproof paper tube, in this article, the paper tube structure is formed by winding outside two sets of end sleeves. When items are stored inside the support inner sleeve, when the outside of the paper tube structure is stacked and squeezed, the paper tube structure can first be preliminarily elastically supported and cushioned by the elastic sheets placed inside the assembly grooves. When the elastic sheets continue to be compressed and deformed, the protective air bags sleeved outside the support inner sleeve can provide elastic support force and cushioning effect to the elastic sheets through the air pressure inside the protective air bags, increasing the compression resistance of the paper tube structure itself, avoiding excessive compression and direct deformation and bending, so as to achieve the effect of improving the compression resistance of the paper tube structure itself and ensuring the safety of item packaging.

[0011] 2. For this new type of compression-resistant and waterproof paper tube, a polyethylene film layer is provided on both the inner side of the support inner sleeve and the periphery of the paper tube structure. The polyethylene film layer itself has waterproof characteristics. In this way, through the provided polyethylene film layer, liquid can be effectively prevented from directly contacting the paper tube structure itself and getting damp, so as to achieve the effect of improving the waterproof effect of the paper tube structure.
