JPH0847422A - Toothbrush equipped with fur-scraper - Google Patents

Abstract

PURPOSE:To provide a toothbrush which can scrape fur on the tongue and also does not become dirty by a method wherein a recessed part is provided on either one or both of the rear surface and side surface of a locked part, and a fur-scraping blade is formed at a corner which is formed between the side surface of the recessed part and the rear surface of the flocked part. CONSTITUTION:For example, a recessed part 5 wherein the shape is slightly smaller than the rear surface of a flocked part, and the depth is uniform is provided on the rear surface 4 of the flocked part, and a fur-scraping blade 7 is formed at a corner between the side surface 6 of the recessed part and the rear surface 4 of the flocked part. The sharpness of the fur-scraping blade 7 is not as sharp as cutting the inside of the mouth but sharp enough to scrape fur on the tongue off. When a user brushes teeth, the fur-scraping blade 7 hits the inside of the mouth, but the fur-scraping blade 7 has a sharpness at a degree wherein the inside of the mouth is not cut, and teeth can be brushed without hurting the inside of the mouth. Before or after brushing teeth, the rear surface 4 of the flocked part is made to face the tongue, and the fur- scraping blade 7 is favorably brought into contact with the tongue, and fur on the tongue is scraped from the inside to the outside of the mouth. This motion is repeated several times. At this time, the scraping is done under a condition wherein the tongue is stiffened by applying some force.

A tongue coating scraping blade (7) is formed so that the tongue coating can be scraped off at the corner formed by the back surface (4) of the part. The recessed part (5) here means a dent, a groove, a hole,
It means an indentation such as a step. The recess (5) may be in one place or in more than one place. The tongue coating scraping blade (7) should be sharp enough not to cut the inside of the mouth. The size, shape, depth, height, etc. of the recess (5) may be changed. For example, various shapes such as a continuous groove, a circle, a triangle, a square, a polygon, an ellipse, a diamond, and a trapezoid can be considered as the shape of the recess (5) when viewed from above. The corners of the concave portion (5) where the tongue coating scraping blade (7) is not formed may be rounded so as to prevent water and dust from accumulating and to suppress the propagation of sterilization. By changing the height of the side surface (6) of the concave portion, the bottom side can be inclined, and various side surface shapes can be considered. That is, it is conceivable that the recess (5) has various sectional shapes. Also, the back side (4) of the flocked part and the side face (3) of the flocked part
Keep the sharpness of the corners so that the inside of the mouth cannot be cut. Moreover, the tip of the protrusion itself or the surface of the protrusion (10)
May be sharpened or formed to have a small roundness, and the tip itself may be a tongue coating scraping blade (7).

A toothbrush with a tongue coating scraper having a tongue coating scraping blade (7) formed by providing a recess (5) on either or both of the back surface (4) of the hair implanting portion and the side surface (3) of the hair implanting portion. You may provide a convex part (8) in a concave part (5). The height of the convex portion is preferably about the same as the depth of the concave portion. The tongue coating scraping blade (7) is formed at the corner between the side surface of the convex portion and the surface of the convex portion. Various shapes can be considered for the convex portion.

A toothbrush with a tongue coating scraper having a tongue coating scraping blade (7) formed by forming a recess (5) on either or both of the back surface (4) and the side surface (3) of the flocked portion. A tongue coating scraping brush (11) may be implanted in the recess (5). The tongue coating scraping brush (11) may have a circular shape, a long connected shape, or may be provided at one place or at one or more places.

A convex portion (8) is provided on either or both of the back surface (4) of the bristle portion and the side surface (3) of the bristle portion, and a corner formed by the side surface (6) of the convex portion and the back surface (4) of the bristle portion. It has a tongue coating scraping blade (7) formed on it. There may be one convex portion (8) or one or more convex portions. Tongue coating scraping blade (7)
The sharpness of should be such that the mouth is not cut. The size, shape, depth, height, etc. of the convex portion (8) may be changed. For example, various shapes such as continuous grooves, circles, triangles, squares, polygons, ellipses, diamonds, and trapezoids can be considered as the shape of the convex portion (8) when viewed from above. The height of the protrusions (8) may be changed, and various side shapes of these side surfaces can be considered. That is, various shapes of the cross section of the convex portion (8) are possible.
Further, the sharpness of the corner formed by the back surface (4) of the flocked portion and the side surface (3) of the flocked portion may be set so that the inside of the mouth is not broken.

A convex portion (8) is provided on one or both of the back surface (4) of the bristle portion and the side surface (3) of the bristle portion, and a corner formed by the convex side surface (9) and the convex surface (11) is formed. The tongue coating scraping blade (7) may be formed on any one or both of the corners formed by the back surface (4) of the flocked portion and the side surface (3) of the flocked portion. As for the shape of the convex portion (8), various shapes can be considered like the concave portion.

The combination of the concave portion (5) and the convex portion (8) may also be various combinations. For example, a concave portion is formed on the back surface (4) of the flocked portion and a convex portion (8) is formed on the side surface (3) of the flocked portion.

[0010]

The toothbrush with a tongue coating scraper according to the present invention is used as follows. When brushing your teeth, brush your teeth as you always have. In this state, the tongue coating scraping blade (7) hits the inside of the mouth, but since the tongue coating scraping blade (7) is sharp enough not to cut the inside of the mouth, it is possible to brush the teeth without damaging the inside of the mouth. it can. Before brushing the teeth or after brushing the teeth, slightly apply the tongue coating scraping blade (7) on the back surface (4) of the flocked portion or the side surface (3) of the flocked portion to the tongue.
The tongue is soft and deforms in various ways, so the tongue coating scraping blade (7)
Bites into the surface of the tongue. The tongue coating scraping blade (7) does not cut the inside of the mouth, but it is sharp enough to scrape the tongue coating. In this state, pull the toothbrush out of the mouth to remove the tongue coating. Can be scraped off. Repeat this several times.
