Description

Technical Field

[0001] The utility model relates to the field of paper tubes, in particular to an antibacterial paper tube. Background Art

[0002] The paper roll is usually placed in the bathroom and fixed by the paper roll holder. Because the bathroom environment is relatively humid, the paper roll placed for a long time is prone to bacteria, which reduces the hygiene and cleanliness. In addition, the inner core diameter of the conventional paper roll is generally about 2 cm, while the diameter of the shaft rod on the paper roll holder is 0.5 cm or even thinner. Therefore, when the paper roll is hung on the shaft rod and rotates due to the paper withdrawal, it often moves, making the paper roll easily slip off the shaft rod. Therefore, the paper tube in the existing paper roll has many inconveniences when used in daily life. Utility Model Content

[0003] The purpose of the present application is to provide an antibacterial paper tube, aiming to solve the problems existing in the prior art.

[0004] The embodiment of the present application provides an antibacterial paper tube, comprising an inner support tube, an outer tube is sleeved on the outer side of the inner support tube, a drying interlayer is arranged between the inner support tube and the outer tube, a plurality of drying tubes are arranged in a single-layer ring in the drying interlayer, the drying tubes, the inner support tube and the outer tube are of equal length, and the drying tubes are half filled with desiccant particles; end caps are fixed at both ends of the paper tube, and the end caps are in a circular shape to close the ports of the drying interlayer;

[0005] A core tube is arranged inside the inner supporting tube, and the diameter of the core tube is 1 / 3-1 / 2 of the diameter of the inner supporting tube; the core tube and the inner supporting tube are connected by a W-shaped supporting paperboard.

[0006] Furthermore, the cross section of the drying tube is hexagonal, the vertices of two adjacent drying tubes are opposite to each other, and an air cavity is formed between the outside of the drying tube and the inner supporting tube and the outer surface tube.

[0007] Furthermore, an air hole penetrating the tube wall is provided on the outer tube at a position corresponding to the drying tube, and the diameter of the air hole is smaller than the particle diameter of the desiccant particles.

[0008] Furthermore, the supporting paperboard includes two radially extending straight plates and a bent plate located outside the core tube and connecting the proximal ends of the two straight plates. The bent plate is fixedly connected to the core tube, and the distal ends of the two straight plates are fixed on the inner supporting tube.

[0009] Furthermore, there are two supporting paperboards, which are symmetrically installed on both sides of the core tube.

[0010] Furthermore, the inner diameter of the end cover is equal to the inner diameter of the inner support pipe, and the outer diameter of the end cover is equal to the outer diameter of the outer pipe.

[0011] The utility model has the following beneficial effects: the utility model provides a paper tube with a drying interlayer, and the external air can contact the desiccant particles in the drying interlayer through the pores on the surface of the paper tube. When a paper towel is wound on the paper tube, the paper towel can have the effect of absorbing moisture, preventing moisture and preventing bacteria. A core tube with a smaller diameter is arranged inside the paper tube to reduce the free space between the core tube and the shaft rod of the paper roll holder, thereby reducing the slippage of the paper roll on the shaft rod when the paper roll rotates, and avoiding the problem of the paper roll slipping off the shaft rod.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1 and Figure 2 As shown, an antibacterial paper tube comprises an inner support tube 1, an outer tube 2 is sleeved on the outer side of the inner support tube 1, a drying interlayer is formed between the inner support tube 1 and the outer tube 2, a plurality of drying tubes 3 are arranged in a single-layer ring in the drying interlayer, the drying tubes 3, the inner support tube 1 and the outer tube 2 are of equal length, and the drying tube 3 is half filled with desiccant particles 4. The type of the desiccant particles 4 is conventionally selected, and is used to dry and absorb moisture on the paper tube itself and the paper towels wrapped thereon to prevent the growth of bacteria.

[0019] The half-filled desiccant particles 4 have space to roll back and forth in the drying tube 3, and a rustling sound can be generated as the paper tube is taken. On the one hand, the amount of desiccant particles 4 can be saved, thereby saving costs. On the other hand, the generated sound can form a unique sound mark, which is interesting and conducive to market promotion.

[0020] The cross section of the drying tube 3 is hexagonal, with an X-shaped paperboard fixed in the middle. The X-shaped paperboard, the outer tube 2 and the inner support tube 1 form a hexagonal shape, which can increase the internal space of the drying tube 3 to more centrally accommodate more desiccant particles 4. The vertices of two adjacent drying tubes 3 are opposite to each other, and an air cavity 5 is formed between the outside of the drying tube 3 and the inner support tube 1 and the outer tube 2.

[0021] End caps 6 are fixed at both ends of the paper tube. The inner diameter of the end caps 6 is equal to the inner diameter of the inner support tube 1, and the outer diameter of the end caps 6 is equal to the outer diameter of the outer tube 2, so that the end caps 6 are annular and close the ports of the drying interlayer. The end caps 6 are fixedly connected to the end faces of the inner support tube 1, the outer tube 2 and the drying tube 3 by gluing to seal the desiccant particles 4 inside the drying tube 3. The finished product is as follows Figure 3 shown.

[0022] In order to facilitate the desiccant particles 4 to absorb moisture from the paper towels wrapped around the paper tube, air holes 7 penetrating the tube wall are provided on the outer tube 2 at positions corresponding to the drying tube 3, and the aperture of the air holes 7 is smaller than the particle size of the desiccant particles 4. The air holes 7 allow the paper towels to be connected to the drying tube 3 by air, which facilitates the absorption of moisture from the paper towels.

[0023] like Figure 1 and Figure 2 As shown, a core tube 8 is arranged inside the inner support tube 1, and the diameter of the core tube 8 is 1 / 3-1 / 2 of the diameter of the inner support tube 1, which matches the diameter of the shaft rod on the paper roll stand for mounting the paper roll, so that the paper roll on the paper roll stand can be rolled out more stably.

[0024] The core tube 8 is connected to the inner support tube 1 through a W-shaped support paperboard 9W. The support paperboard includes two radially extending straight plates 10 and a curved plate 11 located outside the core tube 8 and connecting the proximal ends of the two straight plates 10. The curved plate 11 is fixedly connected to the core tube 8, and the distal ends of the two straight plates 10 are fixed to the inner support tube 1.

[0025] There are two supporting paperboards, which are symmetrically installed on both sides of the core tube 8 to fix the core tube 8 at a position concentric with the paper tube.

[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
