JP3104356U - Boss type upright cylindrical toothbrush - Google Patents

Abstract

An object of the present invention is to provide a boss-type continuous cylindrical toothbrush which is gentle on gums, oral mucosa, and enamel, is hygienic, and can be mass-produced.
A boss portion (b) is formed on one or both sides simultaneously with the welding of a thread material group, and a length of the disc-shaped boss-equipped brush end portion (a) is arbitrarily set.

Description

The present invention relates to a brush for brushing teeth.

The present inventors have previously proposed a cylindrical toothbrush (Japanese Patent Application No. 2003-376298) in which the brush of the toothbrush corresponds to 360 ° with respect to the tooth surface.
The contents are 1. 1. A toothbrush in which the handle shaft is used as a through hole and an appropriate number of annular bristle brushes are passed through, and the leading end of the through hole is welded. To arrange the appropriate number of annular bristle brushes at equal intervals with the handle shaft as the through-hole, the toothbrush with the bristle bristle brush and washer alternately passed through and the tip end of the through-hole welded is there.

In the cylindrical toothbrush 1 in which the brush of the conventional toothbrush described above corresponds to 360 ° with respect to the tooth surface, the brush density is high and not only between the teeth, but also the polishing power is strong. I was worried about getting hurt. Solving these problems

Solved the problem that the brush density was too high, so that even after washing after use, ventilation was poor and drying took time and was unsanitary

In the case of the cylindrical toothbrush 2 corresponding to 360 ° in which the annular bristle brush and the washer were alternately passed, foreign matter was mixed between the brush and the washer, and was unsanitary. Mitigating this problem

It takes a long time to alternately pass through the annular bristle brush and washer, which solves the enormous assembly cost, stabilizes product standards, realizes mass production, and significantly reduces sales prices.

Significant increase in strength of annular bristle brush

The bosses, b and e, are formed on one or both sides simultaneously with the welding of the thread group (see FIG. 2).

The length of the brush end portion a with the disk type boss is arbitrarily added and molded (see FIG. 1).

By forming the bosses b and e on one or both sides, a space is created between the brushes, and there is no fear of damaging the gums, oral mucosa, and enamel due to the reduced brush density.
In addition, by making the length of the brush tip portion a with the disc type boss arbitrarily, it is more gentle on the gums, oral mucosa, and enamel, and the brush tip portion reaches the interdental and last molars, so that accurate brushing can be performed It became so. (For 0003 descriptions)

In terms of hygiene, by forming the bosses b and e on one or both sides, the ventilation is good and the use of a brush alone does not use a washer or the like.
(For 0004,0005 description)

The work of alternately passing the annular bristle brush and washer was time consuming.
Since this work is performed with a single brush having bosses b and e on one or both sides, the assembling time is reduced by half, and mass production and a drastic reduction in selling price are realized. (0006 description section)

By forming the bosses b and e on one or both sides, the welding area was increased and the strength was increased (description of 0007).

The brush material can be made from a nylon thread to a material having a sterilizing and antibacterial action (such as an ionic effect material made of pine ore), which has a more hygienic effect.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

1 and 2 are a plan view and a side view, respectively, of a brush with a disk-type boss.
Unlike a conventional annular bristle brush, there is a single boss b or both bosses e over the entire outer periphery of the central hole c.

The tip a of the brush with the disk-shaped boss is formed of a portion having a length of about 2 m / m. This part also enabled brushing between teeth and the last molar part.

Insert the appropriate number of disk-type bossed brushes (FIG. 1) into the handle g, and weld the handle tip welding portion f to complete the toothbrush.

Unlike a cylindrical toothbrush (Japanese Patent Application No. 2003-376298), in which the brush of a conventional toothbrush corresponds to the tooth surface by 360 °, the length and width of the brush tip can be formed at the same time as the brush molding.

If a material having a melting component such as nylon is the main component, it is easy to manufacture a brush with a disk-type boss even if a natural stone component such as pine ore is included.

Claims (3)

A boss-type upright cylindrical toothbrush made of a plurality of stacked cylindrical toothbrushes, the thread material group of which is opened in a radial direction, a central portion is welded in a ring shape, and a disk-shaped boss having an arbitrary protrusion on one or both sides thereof. With brush alone A brush with a disk-shaped boss having a brush tip portion divided into long and short parts according to claim 1. A boss type upright cylindrical toothbrush in which a large number of disk type bossed brushes according to claim 1 and 2 are inserted into a toothbrush handle and the tip portions are welded.
