Abstract

A cotton swab that can be used favorably for cleaning the ear canal as a daily consumable.
A cotton swab includes a shaft body and a fiber assembly portion having a substantially triangular prism shape in which fibers are wound and bonded to at least one end of the shaft body. The periphery of the peripheral side surface 21 of the fiber assembly part 2 may have a cross-sectional shape in which three or more circular shapes are assembled. On the other hand, the peripheral edge of the peripheral side surface 22 of the fiber assembly portion 2 may have a cross-sectional shape of approximately 60 °.

Description

  The present invention relates to a cotton swab that can be used for daily cleaning tools and other various applications.

(1) Conventionally, a cotton swab in which fibers are formed in a lump shape at the end of a shaft has been used as a cleaning tool for the ear canal. In general, those having a spherical fiber body (cotton ball part) formed from fibers at the tip are used.
(2) In addition to the spherical cotton swab described in the preceding paragraph, a fiber body having an irregular shape perpendicular to the axial direction is provided at the tip of the shaft body.
(3) An agglomerated portion at the tip of the shaft is provided with adsorptivity.

(1) When removing the earwax from the ear canal using the cotton swab having the shape of claim [0002] (1), if the cotton ball part is pulled out in the direction of the ear canal while making contact with the inner surface of the ear canal, The range that can be removed is only the contact surface with the block. In this case, it is necessary to insert and remove the cotton ball part many times in order to remove the earwax around the inner periphery of the ear canal.
(2) Similarly, when removing earwax from the ear canal using a cotton swab having the shape of claim [0002] (1), after inserting the cotton ball part into the inner surface of the ear canal and bringing the cotton ball part into contact with the inner surface of the ear canal The method of removing the ear wax on the inner surface of the ear canal by rotating the cotton swab itself is predicted to be unable to be completely removed by one rotation because the ear wax adhering to the cotton ball part contacts the inner surface of the ear canal again.
(3) When the swab having the shape of claim [0002] (2) is used, the fibrous body is uneven in a direction substantially perpendicular to the rotation direction even by the method of rotating the swab itself described in (2) above. The range in contact with the inner surface of the ear canal is smaller than the range using the swab of [0002] (1).
(4) When the swab having the shape of claim [0002] (3) is used, the lump portion at the tip has adsorbability, so even if the swab itself is rotated, it is adsorbed on the inner surface of the ear canal. However, since it rotates, it gets caught and smooth removal of the earwax is not easy.

  Said problem is solved by providing the lump part at the tip of a cotton swab with the recessed part parallel to a shaft.

  The above-mentioned problem is solved by forming a part of the lump at the tip of the swab into a triangular prism shape.

(1) By providing a concave portion parallel to the shaft body in the lump portion at the tip of the cotton swab, it is possible to collect ear wax in the concave portion while ensuring a contact range with the inner surface of the external ear canal, so that the removed ear wax is again applied to the inner surface of the ear canal Can reduce contact.
(2) The same effect as the above [0006] (1) can be expected by forming a part of the lump at the tip of the swab into a triangular prism shape.

It is a perspective view of the cotton swab which concerns on one Embodiment of this invention. It is a side view of the cotton swab which concerns on one Embodiment of this invention. It is a partial expanded sectional view which shows the fiber assembly part of a cotton swab.

  Hereinafter, the cotton swab of the present invention will be described with reference to the drawings. FIG. 1 shows a cotton swab according to an embodiment of the present invention.

  As shown in FIG. 1, a cotton swab according to an embodiment of the present invention includes a shaft body 1 and a fiber assembly portion 2 at one end or both ends of the shaft body 1.

  Examples of the shaft body 1 include a paper shaft, a plastic shaft, and a wooden shaft. In the case of a paper shaft, for example, it is manufactured by applying an adhesive to one side of a paper sheet punched into a rectangle and winding it small. Examples of the cross-sectional shape of the shaft body 1 include a circle, an ellipse, a flat shape, and a square. The tip surface of the shaft body 1 may be chamfered or curved.

  As shown in FIG. 3, the fiber assembly portion 2 is formed by winding and bonding fibers around the end portion of the shaft body 1. The fiber assembly portion 2 is formed in a shape 21 having a circumferential side surface in which three cylinders having the same diameter are aggregated except for a lower end and an upper end of the circumferential side surface, or a substantially triangular prism shape 22 having substantially the same side length. . The tip end (top surface) of the fiber assembly portion 2 is hemispherical. Therefore, it is possible to remove the earwax adhered to the inner surface of the ear canal without damaging the inside of the ear canal when inserted into the ear canal. Further, an adhesive that is harmless to the human body may be applied to the peripheral side surface and the front end surface of the fiber assembly portion 2 to adhere ear wax or the like.

  The ratio of the outer diameter and the length of the fiber assembly part 2 is preferably about 1: 5. The length of the fiber assembly part 2 is preferably about 5 to 20 mm, and the outer diameter is about 2 to 5 mm.

  Examples of the fibers forming the fiber assembly part 2 include various natural fibers (cotton, silk, wool, etc.), regenerated fibers (rayon, cupra, etc.), synthetic fibers (polyester fibers, polypropylene fibers, etc.), and the like. However, cotton fibers such as absorbent cotton having particularly good hygroscopicity are preferably used. These fibers may be used alone or in combination of two or more.

  The fiber assembly part 2 is formed by applying a lower paste to the fiber assembly part shaft body 2 and then winding and bonding the fibers. Examples of the lower paste used when the fiber assembly portion 2 is bonded to the fiber assembly portion shaft body 2 include starch paste, polyvinyl alcohol, ethylene vinyl acetate copolymer, and carboxymethyl cellulose.

In the cotton swab, when the fiber assembly part 2 is formed only at one end of the shaft body 1, the other end side of the shaft body 1 is different from the grip part that is easy to hold and the fiber assembly part 2. You may provide the fiber assembly part (not shown) etc. of a shape (for example, spiral shape, spoon shape, etc.). Moreover, when the fiber assembly part 2 is formed in the both ends of the shaft 1, the dimension, shape, etc. of each fiber assembly part 2 may differ.
Furthermore, when the fiber assembly part 2 is impregnated with a solvent or the like, the cotton swab is preferably sealed with a container or bag until just before use.
