Abstract

(57) [Summary] [Purpose] To provide a paper shaft that is made of recycled paper and is suitable for shafts such as cotton swabs and ear picks. [Structure] The raw paper 2 is a recycled paper made from waste paper using long fibers. The paper shaft 1 is made by winding the raw paper 2 solidly, and when winding the paper, the axial direction is made to coincide with the direction of the fibers 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper shaft used as a shaft of a cotton swab or an earpick.

[0002]

[Prior art]

 Conventionally, plastic shafts and paper shafts are usually used for the shafts of cotton swabs and earpicks. Of these, the paper shaft is made from groundwood pulp as a main raw material, and the paper is cut in the longitudinal direction according to the required axial length and has the required thickness (diameter of about 1 to 2 mm). It is made by winding.

[0003]

[Problems to be solved by the device]

 Swabs and earpicks are now mostly disposable. For this reason, expensive shafts cannot be used. Conventionally, the reason why the paper made from groundwood pulp is used as the raw material paper for the paper shaft is mainly because it is inexpensive. However, all pulp used here is virgin pulp. No waste paper pulp is used. Since paper shafts such as cotton swabs need to have a certain level of strength, it is not possible to use waste paper pulp with poor strength. However, the use of virgin pulp for the paper axis of a disposable cotton swab is extremely wasteful in terms of resource utilization and is a great waste of global resources.

In view of such a point, the present invention intends to effectively utilize resources by using recycled paper from waste paper pulp, and to provide a paper shaft excellent in strength.

[0005]

[Means for Solving the Problems]

 The technical means of the paper shaft of the present invention uses recycled paper made from waste paper using long fibers as the raw paper, and when winding the raw paper, make the axial direction match the direction of the paper fibers. It's about winding.

In addition, it is preferable to use recycled paper made from waste paper of a milk carton as the raw paper.

[0007]

[Action]

 The paper shaft of the present invention uses recycled paper made from waste paper using long fibers as the raw material paper. Therefore, even after the stage of recycling, the fibers are sufficiently long and have the necessary strength as a raw material for the paper shaft. In the case of machine making, paper fibers are aligned in the machine direction, that is, in the feed direction of the paper machine. Therefore, when winding the raw paper, if you wind it with the axial direction aligned with the direction of the fiber, the finished paper shaft will have strong strength against bending and will not easily break, because the fibers are oriented in the axial direction. It becomes a paper axis.

Since the milk carton paper has very high quality and long fibers, the recycled paper made from this waste paper is extremely excellent as a raw paper.

[0009]

【Example】

 An embodiment of the paper shaft of the present invention will be described with reference to the drawings. Reference numeral 1 is a paper shaft, which is made by winding a raw paper 2 into a solid. As the raw paper 2, recycled paper made from waste paper pulp is used. However, the waste paper used as the raw material for pulp is not normal waste paper, but is limited to long-fiber waste paper, such as milk pack paper.

When winding the raw paper 2, the axial direction of the winding work is made to coincide with the direction of the fibers 3 of the paper. Since the fibers 3 of the paper are aligned in the longitudinal direction of the paper, that is, in the feeding direction of the paper machine, the longitudinal direction is defined in the axial direction of winding. As a result, in the finished paper shaft 1, the fibers 3 are oriented in the axial direction, and the strength against bending is high. In the conventional paper shaft manufacturing, since the paper is wound from the drum winding state and continuously manufactured while being wound, the fibers are oriented in the winding direction, and the finished paper shaft has low bending strength.

The dimensions of the paper shaft of the present invention are usually about 0.5 to 5 mm in diameter and about 5 to 15 cm in length, but can be appropriately determined depending on the application. Since the paper shaft of the present invention has a high bending strength, it can be made thinner or longer than usual.

FIG. 2 shows a shaft of a cotton swab, in which cotton 5 is wound around the end of the paper shaft 1. FIG. 3 is used for the shaft of an earpick, and a curved flat portion 6 is formed on the end portion of the paper shaft 1 by press working. Since such press processing is performed during the manufacture of earpicks, it is necessary for the shaft to have high strength, and the paper shaft of the present invention also meets this requirement.

The present invention is not limited to the above-described embodiment, and can be freely modified and implemented within the scope of the utility model registration claim.

[Effect of device]

 The paper axis of the present invention uses recycled paper as the raw paper, and is therefore superior in terms of effective use of resources. In addition, since recycled paper made from waste paper using long fibers is used and the axial direction of winding is matched with the direction of the fiber, the finished paper axis has the fibers oriented in the axial direction and It has high strength, is hard to break, and has excellent performance as a paper shaft such as a cotton swab.

According to the second aspect of the present invention, since recycled paper made from waste paper of a milk carton is used, the length of the fiber is sufficient and it is relatively easy to obtain, which is advantageous in manufacturing.
