Problems solved by technology

[0010] The toothbrush described in the previous patent document 1 has excellent interdental cleanability, a soft touch to the gums, and a high brushing feeling. However, when the bristles are planted or used, there is a problem that the bristles with a clover-shaped cross section are easy to Cracked downside
[0011] In addition, in the toothbrush described in the previous patent document 2, since the branched hairs are densely packed inside the outer peripheral position on the tip side of the bristles, there is a disadvantage that a sufficient brushing feeling cannot be obtained due to the provision of the branched hairs.

no. 1 Embodiment approach

[0072] Next, a first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0073] Figure 1A It is a figure which shows the toothbrush A implanted with the tapered bristle of 1st Embodiment. This toothbrush A has a head 2, a neck 3, and a grip 4 on which a plurality of hair bundles 1 are implanted, and the head 2, neck 3, and grip 4 are made of a hard resin material.

[0074] The hard resin constituting the head 2, the neck 3, and the grip 4 can be polypropylene resin or polyester resin, but it can also be made into a two-color molded product in which the surroundings of these hard resins are covered with soft resin.

[0075] Examples of the soft resin include elastomer resins such as polyolefin-based elastomers, styrene-based elastomers, and polyester-based elastomers.

[0076] As the resin used here, any resin suitable for general toothbrushes may be used.

[0077] The hair bundle 1 implanted in the head 2 of the too...

no. 2 Embodiment approach

[0117] Figure 3A ~B is a diagram showing tapered bristles 15 according to the second embodiment of the present invention, Figure 3A is a plan view of the top portion of the tapered bristle 15, Figure 3B is a perspective view of tapered bristles 15.

[0118] Figure 3A The tapered bristles 15 of the second embodiment of the present invention shown in ~B are implanted on the hard resin head in the same way as the tapered bristles 5 of the previous first embodiment to constitute a toothbrush.

[0119] The tapered bristle 15 of the present embodiment is as Figure 3B Shown in enlargement, four tapered bristle bodies 16 made of resin are integrated at the central side of the cross section of the tapered bristle 15 to form a tapered bristle assembly part 19, and all or a part of the sides of the integrated part are respectively It is covered with the covering part 17 made of resin. On the tip side of the tapered bristle body 16, a tapered portion 16A having a tapered tip is ...

no. 3 Embodiment approach

[0132] Figure 4A ~B is a diagram showing the tapered bristles 25 according to the third embodiment of the present invention, Figure 4A is a top view of the top portion of the tapered bristles 25, Figure 4B is a perspective view of tapered bristles 25.

[0133] Figure 4A The tapered bristles 25 of the third embodiment shown in ~B are similar to the tapered bristles of the previous embodiments 1 and 2, and are implanted on the head made of hard resin to form a toothbrush.

[0134] The tapered bristle 25 of the present embodiment is as Figure 4A As shown in the enlarged view, three tapered bristle bodies 26 made of resin are integrated at the central side of the cross section of the tapered bristles 25 to form a tapered bristle assembly part 29, and all or part of the side surfaces of the integrated part Each is covered with a resin covering part 27 .

[0135] On the tip side of the tapered bristle body 26, a tapered portion 26A having a tapered tip is formed. The port...

Abstract

A tapered bristles, including: cone -shaped bristles, which are adjacent to the cone bristles made of more than 3 resin made of more than 3 and 10 resin.They all have the cone -shaped part; and the covered part of the resin is covered with all or part of the side or part of the side of the cone -shaped bristles to integrate the side of the cone -shaped bristle body.All or part of the sides of the tapered part of the body are covered by the side or part of the side, and the external edge of the outer edge of the except cone -shaped part of the cone bristles is highlighted to the outer side of the except cone -shaped part.

Description

technical field [0001] The present invention relates to a tapered bristle having a branched tip portion, a manufacturing method thereof, and a toothbrush having the tapered bristle. [0002] this application claims priority based on Japanese Patent Application No. 2012-211159 for which it applied to Japan on September 25, 2012, and uses the content here. Background technique [0003] To prevent periodontal disease, tapered bristles (super fine bristles) with sharpened tips are widely used as bristles whose bristles are soft to the touch and can reliably clean the back of periodontal pockets. As an example of sharpened tapered hairs at the tip, there is known a tapered monofilament that is 1mm, 3mm, 5mm, 8mm away from the tapered tip for the tip of the synthetic resin monofilament. The bristle diameter of each part is specified as 25-35%, 55-70%, 80-90%, 90-100% of the outer diameter of the bristle base, and it is known that there is such a monofilament planted on the top of...
