Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention has a moderate massage effect on gums and the like and a high tooth surface cleaning effect, and the central part of the brush part has a metallic luster. The present invention relates to a toothbrush having high consumer suction power.

[0002]

2. Description of the Related Art In order to enhance the effect of removing plaque and adhering substances on the teeth and the effect of massaging gums, etc., or to enhance the appeal of products and the attractiveness of consumers. Various toothbrushes in which two or more kinds of bristles having different shapes, colors, etc. are planted are known. Further, a toothbrush in which different types of bristles are implanted on the inside and outside in the width direction of the flocking table is also known, for example, from Japanese Utility Model Publication No. 3-351.
No. 47 is known. However, in the toothbrush described in the utility model publication, the bristles implanted on the inner side in the width direction of the flocking table are of a high hardness containing abrasive particles or having abrasive particles adhered to the surface thereof, so that the brushing force is high. Some of them may cause excessive irritation to the gums and tooth polishing.

Accordingly, an object of the present invention is to provide a toothbrush which has a moderate massage effect on gums and the like and a high tooth surface cleaning effect, and has a novel and beautiful appearance of a brush portion, and has a high product appealing power and a high consumer suction power. To provide.

[0004]

According to the present invention, a bristle bundle B containing no metal foil is planted on at least both outer sides in the longitudinal direction of a flocking table, and a bristle bundle A containing a metal foil is placed inside the bristle bundle B. The object has been attained by providing a toothbrush having a brush portion in which hair is planted.

[0005]

According to the toothbrush of the present invention, the bristle bundle A containing the metal foil planted inside the flocking table has an appropriate hardness, and at least both sides of the bristle bundle A do not contain the metal foil. Therefore, even if brushing is performed with a strong force, a moderate massage effect and a high tooth surface cleaning effect are exhibited without damaging the gums and the tooth surface. The bristles of the bristle bundle A containing a metal foil have fine irregularities formed on the surface by the metal foil, and the irregularities further enhance the tooth surface cleaning effect.
In addition, the toothbrush of the present invention has a metallic luster at the center of the brush portion on which the bristle bundle A containing the metal foil is planted, and presents a novel and beautiful appearance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a toothbrush according to the present invention will be described below in detail with reference to the drawings.

FIGS. 1 and 2 are schematic plan views showing one example of the arrangement of flocking of two types of bristle bundles A and B in the brush portion of the toothbrush of the present invention. The toothbrush of the embodiment shown in FIG. 1 has a brush portion 1 in which a plurality of bristles bundles in which a number of bristles are bundled are planted in four rows in the width direction of the planting table 2. And the brush part 1
The bristle bundles of one row each planted on both outer sides in the longitudinal direction of the flocking table are formed from the bristle bundle B containing no metal foil, and the two rows of bristle bundles planted inside the bristle bundles,
It is formed from a bristle bundle A containing a metal foil.

Further, as the bristles containing the metal foil constituting the bristle bundle A, a metal foil such as an aluminum foil, a gold foil, a silver foil or a stainless steel foil is kneaded with a synthetic resin such as nylon, polypropylene, polybutylene terephthalate or the like. Is preferred, and among these, nylon bristles in which aluminum foil is kneaded are particularly preferred. Further, the content of the metal foil in the bristle containing the metal foil,
In the case of a synthetic resin bristle kneaded with the metal foil,
It is preferably 0.3 to 6 parts by weight based on 100 parts by weight of the synthetic resin. Preferably, the size of the metal foil kneaded in the synthetic resin is 0.001 to 0.1 mm ² in plan view and 3 to 40 μm in thickness. The bristles constituting the bristle bundle A into which such a metal foil is kneaded are, for example, TYNEX (trade name) manufactured by DuPont.
X), and such a commercially available product may be used in the present invention.

The bristle bundle B containing no metal foil is an ordinary synthetic resin bristle bundle or a bristle bundle made of natural hair such as animal hair.

The bristle bundle A may contain 40% or less of the ordinary bristle constituting the bristle bundle B, and the bristle bundle B contains a metal foil constituting the bristle bundle A. May be contained by 40% or less. The ratio between the number of the bristles bundle A and the number of the bristles bundle B is A / B = 1/18.
１５15/2 is preferred. In the toothbrush of the embodiment shown in FIG. 1, the brush part 1 is connected via a neck part 3 to a grip part (not shown) similar to a grip part in a conventional toothbrush.

Further, the toothbrush of the embodiment shown in FIG.
The bristle bundles A and B are arranged so that the bristle bundles A are all surrounded by the bristle bundles B, with all the bristle bundles at the periphery of the flocking table being the bristle bundles B. Thus, the arrangement state of the bristle bundles A and B is The other configuration is the same as the toothbrush of the embodiment shown in FIG.

The arrangement of the bristle bundles A containing the metal foil and the bristle bundles B containing no metal foil in the brush portion of the toothbrush of the present invention is not limited to the above embodiment. For example, in the embodiment shown in FIG. 1, the bristle bundles A are arranged in two rows, but the bristle bundles A may be arranged in one row or three rows. Also,
In the embodiment shown in FIG. 1, the bristle bundles B are arranged in one row on both outer sides in the longitudinal direction of the flocking table. However, the bristle bundles B may be arranged in two rows. In the embodiment shown in FIG.
The bristle bundles A in the inner row are planted one more at each of both ends in the longitudinal direction of the flocking table than the bristle bundles B in both outer rows according to the substantially elliptical flocking table. The number of bristle bundles may be the same. In the embodiment shown in FIG. 1, the ratio of the bristle bundle A to the row of the bristle bundle B is 70% or less (the number of the bristle bundles A to the number of the bristle bundles B in the row) within a range that does not impair the effects of the present invention. (Ratio of number), and similarly, it is also possible to arrange the bristle bundle B in the row of the bristle bundle A at a ratio of 70% or less. In the embodiment shown in FIG. 2, the bristle bundles A can be arranged in the above-described ratio in each of the rows of the bristle bundles B, each of which is implanted on both outer sides in the longitudinal direction of the flocking table. The bristle bundles B can be arranged at the above ratio in the row of the bristle bundles A surrounded by the bristle bundles B.
