Description
Technical Field
the utility model relates to a paper tube technical field specifically is a paper tube that can use repeatedly many times.
Background
The paper tube is a tubular object processed by paper, most of the paper tubes are spiral paper tubes and seamless paper tubes, most of the existing paper tubes are disposable paper tubes, and the disposable paper tubes are poor in moisture-proof capacity and structural strength, so that the disposable paper tubes are easy to deform or damage after being used and cannot meet the requirement of repeated use.
SUMMERY OF THE UTILITY MODEL
The utility model provides a paper tube that can use repeatedly many times is relatively poor with the dampproofing ability, the structural strength that solve above-mentioned current paper tube that provides, produces deformation or damage easily after the use, can't satisfy the problem that repetitious usage required.
The utility model provides a paper tube that can use repeatedly many times, including paper tube, paper tube stopper, its characterized in that, the paper tube stopper inlays the both ends face at the paper tube, the internal surface bonding of paper tube stopper has sealing rubber, the paper tube includes outer tube core, inner tube core is located the inboard of outer tube core, the surface bonding of outer tube core has outer waterproof layer, the internal surface fixedly connected with circular arc gusset of outer tube core, it has the pearl sponge to fill between circular arc gusset and the outer tube core, the root fixedly connected with support of circular arc gusset, the surface of tube core including the support is inlayed, it has the blotter to fill between support and the inner tube core, the internal surface bonding of inner tube core has interior waterproof layer.
Furthermore, the arc rib plates are in a semi-arc shape and are hollow inside, and the arc rib plates are distributed symmetrically and uniformly around the axis of the paper tube.
Furthermore, the upper surface of the arc rib plate is tangent to the inner surface of the outer tube core.
Furthermore, the sealing rubber is tightly attached to two end faces of the paper tube.
A paper tube capable of being repeatedly used has the following beneficial effects:
Through outer waterproof layer, interior waterproof layer, sealing rubber can make the paper tube have good dampproofing and waterproofing ability, through inside and outside tube core and circular arc gusset structure, can alleviate paper tube gravity and save material the time, can also improve the anti extrusion deformation ability of paper tube, improve the life of paper tube, can be to paper tube used repeatedly many times.

Detailed Description
Please refer to fig. 1 to 3:
The utility model provides a paper tube which can be repeatedly used, comprising a paper tube 1 and a paper tube plug 2, wherein, the paper tube plug 2 is embedded on the two end surfaces of the paper tube 1, and the inner surface of the paper tube plug 2 is bonded with a sealing rubber 201; specifically, the paper tube plug 2 can protect the end face of the paper tube 1 and reduce damage to the end face, and the sealing rubber 201 can be tightly attached to the end face of the paper tube 1 and can prevent moisture from entering the paper tube 1 to prevent moisture from entering the left end and the right end of the paper tube 1;
The paper tube 1 comprises an outer tube core 4 and an inner tube core 7, wherein the inner tube core 7 is positioned on the inner side of the outer tube core 4, an outer waterproof layer 3 is bonded on the surface of the outer tube core 4, an arc rib plate 5 is fixedly connected to the inner surface of the outer tube core 4, a pearl sponge 6 is filled between the arc rib plate 5 and the outer tube core 4, a support 8 is fixedly connected to the root part of the arc rib plate 5, the support 8 is embedded on the outer surface of the inner tube core 7, a cushion pad 9 is filled between the support 8 and the inner tube core 7, and an inner waterproof layer 10 is bonded; and specifically, outer waterproof layer 3, interior waterproof layer 10 can adopt the drenching membrane paper, materials such as parchment paper prevent that aqueous vapor from permeating into outer tube core 4, inner tube core 7, play dampproofing effect, and circular arc gusset 5 utilizes its hollow circular-arc, can alleviate the weight of paper tube 1 and save the material, the circular arc shape can improve the anti extrusion deformability of paper tube 1 simultaneously, and support 8 can play the supporting role, blotter 9 can play some shock attenuation cushioning effects behind circular arc gusset 5 atress, pearl sponge 6 of filling simultaneously, also can play the shock attenuation, dampproofing effect.
