Abstract

<P>PROBLEM TO BE SOLVED: To provide a swab permitting easy cleaning a detail part of a precision apparatus. <P>SOLUTION: Ends of a shaft 1 are wrapped with very thin non-woven fabric 3 which is bonded to the shaft 1. An adhesive agent 3 is impregnated into the non-woven fabric 3 to give adhesiveness to extra-fine cleaning parts 2 and 2a formed of the non-woven fabric 3, so that dust or the like is made to adhere to the cleaning parts 2 and 2a. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

The present invention relates to a cotton swab used mainly as a cleaning tool for details of precision equipment such as tape recorders and personal computers.

Conventional cotton swabs are provided with a cotton ball at the end of the shaft, and are widely used as ear cleaning tools, medical tools, precision machine cleaning tools, and the like.
However, the standard size of the cotton swab is about 80 mm in total length, about 2.5 mm in shaft diameter,
Because the outer diameter of the cotton ball at the tip is about 5 mm, for example, the cotton ball cannot be put into a dense part such as a connector portion connecting a personal computer and an external peripheral device. It had a drawback that the dirt could not be removed.
Even if the cotton balls are forced to enter, the cotton fibers are easily separated and scattered by the uneven parts of the internal parts of the precision equipment, and there is a risk that the scattered cotton fibers may cause a failure of the precision machine. .
Therefore, the applicant of the present application has invented a cotton swab in which the end of the shaft rod is encapsulated with a very thin nonwoven fabric and the shaft rod and the nonwoven fabric are bonded together (see, for example, Patent Document 1), thus eliminating the above-mentioned drawbacks.

However, no matter how good the cotton swabs are, if they are not used skillfully, the dust entangled with the non-woven fabric will be dropped during removal, or when dust is raked out from a fine gap, I couldn't even cover this kind of human error.

In view of the above problems, the present invention encapsulates the end of a shaft rod with a very thin non-woven fabric, adheres the non-woven fabric to the shaft rod, and infiltrates the non-woven fabric with a pressure sensitive adhesive, thereby forming an ultra-fine material formed of the non-woven fabric. The above-mentioned problem is solved by making the cleaning part of the shape have adhesiveness.

In short, the present invention encloses the end of the shaft rod with a very thin non-woven fabric, adheres the shaft rod and the non-woven fabric, and permeates the ultra-thin cleaning portion formed of such a non-woven fabric, thereby having adhesiveness. So, just put the cleaning part into the details of precision equipment, etc. and let it come into contact with dust etc., you can attach dust etc. to the cleaning part. It can be removed reliably without dropping it, and its practical effect is significant.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of a cotton swab according to the present invention, and FIG. 2 is a partial cross-sectional front view of a cleaning unit.
The cotton swab according to the present invention is provided with cleaning portions 2 and 2a at both ends of a shaft rod 1 made of a suitable material such as a metal such as aluminum, paper, plastic, or wood, and the cleaning portions 2 and 2a The adhesive is infiltrated.
As an adhesive, use acrylic adhesive, urethane adhesive, rubber adhesive, etc.
The adhesive may be applied to the surfaces of the cleaning units 2 and 2a, or the cleaning units 2 and 2a may be immersed in the adhesive and the adhesive may be attached to the surfaces of the cleaning units 2 and 2a.

The shaft rod 1 has a length of about 70 mm and a shaft diameter of about 1.5 mm, and is formed into a uniform round bar shape, square bar shape, or other polygonal bar shape over the entire length.
Each of the cleaning portions 2 and 2a is formed by encapsulating the end portion of the shaft rod 1 with a very thin nonwoven fabric 3 and bonding the shaft rod 1 and the nonwoven fabric 3 with a polyethylene-based adhesive. It has an extremely thin cylindrical shape and an outer diameter of about 2 mm.
As the nonwoven fabric 3, for example, Ben Rize (registered trademark) of Asahi Kasei Fibers is good.
It is not limited to this, and is made of cotton fiber, chemical fiber (staple fiber), or mixed fiber thereof, and has a thickness of about 0.25 mm. It is sufficiently strong against tension and breakage, and further absorbs water. It is sufficient that the property and water retention are good and the surface is formed smoothly.
In addition, although the cleaning parts 2 and 2a formed in the both ends of the axial rod 1 were illustrated, you may form in only one end.
Further, the dimensions of the shaft 1 and the cleaning parts 2 and 2a are merely examples, and are not limited.

Next, the operation of the cotton swab according to the present invention will be described.
The cleaning parts 2 and 2a are formed in a very thin cylindrical shape at the end of the shaft 1, and the cleaning parts 2 and 2a are impregnated with an adhesive. It is possible to get into the details without difficulty, and to bring the dust into the cleaning parts 2 and 2a by hitting the desired minute part with a hit.
Further, even if the shaft 1 is rotated while being rotated, the side surfaces of the cleaning parts 2 and 2a are not caught by the uneven portions on the periphery, and the surrounding dust and the like can be attached to the cleaning parts 2 and 2a.
