Description

Paper tube assembly {PAPER TUBE ASSEMBLY}

The present invention relates to a paper tube assembly, and more particularly, to a paper tube assembly that prevents discoloration, migration, shrinkage, odor, and bacterial growth and mold generation of raw materials wound on a paper tube.

A flexible material such as paper, film, or fiber is supplied by winding it in the form of a wound roll, and a core exists at the center of the roll, which serves as a center point during initial winding, and has a cylindrical shape for ease of use.

In addition, the core has various materials depending on the environment in which it is used, such as paper, wood, plastic, metal, and ceramic, and a paper tube made of paper is generally used.

These paper tubes are products that have been traditionally used in industrial fields such as paper (pulp paper) and textiles. Recently, they have been developed in various ways as paper tubes for mounting high-temperature sensors, paper tubes for construction, or packaging containers, and the field of application is diversified. It is a trend that is becoming

13 to 14 , the paper tube according to the prior art winds up raw materials such as pulp paper or fiber fabric, or yarn constituting the fiber fabric, and then seals the outside with a vinyl and then distributes and stores it.

However, the paper tube sealed with vinyl according to the prior art has a serious problem in that it cannot provide clean raw materials to consumers because it lacks a solution to the problem of deformation of raw materials due to internal humidity and internal air.

That is, in the paper tube sealed with vinyl, discoloration, migration, shrinkage, odor emission, bacterial growth, and mold occurred in the wound raw material due to the internal humidity and internal air.

After all, since the paper tube of the prior art has no functionality, there were many cases where each of them was concerned about moisture-proof, anti-bacterial, and deodorization.

For example, in order to solve the above-described problem, even if a desiccant is simply put in a hollow of a plastic tube or a paper tube, the dehumidifying function cannot be efficiently performed.

That is, by first coupling the functional composition pack 200 to the paper tube cap 300 , and coupling the paper tube cap 300 to which the functional composition pack 200 is coupled to the paper tube 100 , the paper tube assembly (A') may be implemented. have.

Alternatively, unlike shown, a composition having an antibacterial and dehumidifying function may be internally added to the branch tube cap 300 itself.

In some embodiments, the paper tube cap 300 including the functional composition pack 200 does not serve as a cap at both ends of the paper tube 100, but along the hollow 120 as shown in FIG. 5 ( 100) may be inserted into the inner space to be fixedly coupled. That is, both ends of the paper tube 100 may be in an open state after the paper tube cap 300 is coupled.

In some embodiments, as shown in FIG. 6 , a through hole for expressing the functionality of the functional composition pack 200 provided inside the paper tube assembly (A''') to the outside of the paper tube assembly (A''') They 310 may be provided in the branch tube cap 300 . In this case, relative degradation occurs in the diffusion rate and range of the antibacterial and moisture-proof ability than in the case where a plurality of through-holes 110 are provided in the branch tube 100 itself, as shown in FIGS. 1 to 5, but the functionality of the present invention The composition pack 200 and the paper tube cap 300 have the advantage of being applicable to the conventional paper tube disclosed in FIG. 13 .
