Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush and is intended to remove dental plaque or the like with improved cleaning ability.

[0002]

2. Description of the Related Art Conventionally, there are toothbrushes having different bristle shapes. The conventional toothbrushes can be classified according to their shapes as shown in Conventional Examples 1 to 5 in Tables 1 to 5.

According to the method of Conventional Example 1, as shown in Table 1, the tufts (1) having the same tuft lengths are tufted on the tufting base (2), and the tips of the tufts (1) are flattened. It was formed in.

Further, the method of Conventional Example 2 is a double-sided bristles in which the flocking lengths are arranged on both sides of the surface of the flocking base (2) as shown in Table 2.
Flock (3). And, in the widthwise spacing of the both-sided bristles (3), long bristles having a longer flocked length than the both-sided bristles (3).
(4) flock the flocking base (2) in the longitudinal direction. By this flocking, the tip shape in the flocking direction is formed into a convex shape.

Further, the method of Conventional Example 3 is a double-sided tufted hair with the length of flocked on both sides of the surface of the flocked base (2) as shown in Table 3.
Flock (3). In addition, the short bundles (5) having a shorter length than the two-sided bundles (3) at the widthwise intervals of the both-sided bundles (3).
By implanting hair, the tip shape in the width direction is provided in a concave shape.

In addition, in the method of Conventional Example 4, taper bristles (6) having a tapered tip end are flocked on a flocking base (2) as shown in Table 4, and the length of the flocking base (2) is changed. The shape in the depth direction is formed into a plurality of chevron shapes.

Further, in the method of Conventional Example 5, long tufts (4) having a long tufting length and short tufts (5) having a short tufting length are alternately arranged as shown in Table 5. (2) is flocked, and the tip shape in the length direction is formed into a plurality of concavo-convex shapes.

[0008]

However, the shape of the teeth is generally rounded and the surface portion is arcuate. Therefore, in the above conventional toothbrush, Table 1 to Table 5
As is clear from the description of "Conventional cleaning effect" in No. 1, it is difficult to clean the groove formed in the gap between the teeth and the boundary between the tooth and the gum at the same time, and the cleaning effect is It was low.

That is, in the method of Conventional Example 1, as shown in Table 1, since the tips of all the bundles (1) are formed flat,
The boundary between the tooth (7) and the gum (9), and the groove formed between the tooth (7) and the tooth
Up to (10), the tufts (1) could not come into contact with each other, and the cleaning effect was extremely low.

[Table 1]

Further, in the method of Conventional Example 2, the long tufts (4) planted at the intervals of the tufts (3) on both sides enable cleaning of the boundary between the tooth (7) and the gum (9). However, in this method, the tip of the long tufts (4) in the longitudinal direction of the flocking base (2) is
Since it is flat as shown in Fig. 7, it is impossible to contact the long tufts (4) to the grooves (10) between the teeth (7) and the teeth, and the cleaning effect on this portion is low. .

[Table 2]

Further, in the method of Conventional Example 3, the double-sided tufts (3) having a long length of flocked can wash the boundary between the tooth (7) and the gum (9). However, according to this method, the tips of the tufts (3) on both sides in the length direction of the flocking base (2) are made flat as shown in Table 3, so that the teeth (7) and the teeth (7) are The tufts (3) on both sides could not come into contact with the groove (10) between them, which was not suitable for washing this portion.

[Table 3]

Further, in the method of Conventional Example 4, the tip of the taper bundle (6) is formed into a plurality of chevron shapes in the length direction of the flocking base (2). The tip of the tooth is the tooth (7)
Allows cleaning of the groove (10) between (7). However, in this method, the tip of the taper bristles (6) is made flat as shown in Table 4 in the width direction of the flocking base (2), so that the teeth (7) and gums (9) are Tapered bundles (6) to the boundary
However, the cleaning effect was low.

[Table 4]

In the method of Conventional Example 5, the tips of the long bristles (4) and the short bristles (5) in the lengthwise direction of the flocking base (2) are
Since it is formed in multiple uneven shapes, the tip of this convex shape
Allows cleaning of the groove (10) between the (7) and the tooth (7). However, according to this method, the tips of the long tufts (4) in the width direction of the flocking base (2) are made flat as shown in Table 5, so that the teeth (7) and gums (9) are It was difficult to wash this part because the long bundles (4) did not reach the boundary.

[Table 5]

As described above, the conventional toothbrush cannot clean both the boundary between the tooth (7) and the gum (9) and the groove (10) between the tooth (7) and the tooth (7). Therefore, the plaque on the uncleaned portion cannot be removed.

The present invention is intended to solve the above-mentioned problems, and it is possible to simultaneously clean the boundary between the teeth and the gum and the groove between the teeth, which has been difficult to clean in the conventional toothbrush. By doing so, it is intended to surely remove plaque.

[0016]

In order to solve the above-mentioned problems, the present invention provides a plurality of double-sided hair bundles with uniform lengths of hair on both sides of the surface of a hair-implanted base provided at the tip of the handle. The hairs are flocked in the length direction of the flocking base via a flocking interval, and the flocked hairs are flocked to the distances of the flocking bases in the widthwise direction of the bristles on both sides. It is configured by hair transplants of the same length and hair transplants shorter than the two-sided hair bundles.

Further, the long and short flocks of the interval tufts alternate between long tufts having the same tuft length as the tufts on both sides and short tufts of tufts shorter than the tufts on both sides. It may be formed in.

The long and short flocks of the interval tufts form long tufts having the same tuft length as the tufts on both sides and short tufts of tufts shorter than the tufts on both sides. However, two short bundles may be arranged at intervals of the long bundles.

The long and short tufts of the interval tufts are formed by forming a pair of tufts having a tapered tip, and long tufts having the same length as the tufts on both sides. The short flock may be formed shorter than the bunch on both sides.

The long flock and short flock of the spacing tufts are formed by forming a pair of tufts having tapered tip portions and tapering the tip of the tufts at a distance between the tufts of the chevron shape. Short tufts shorter than the long tufted long tufts may be arranged.

The double-sided hair bundles and the space-side hair bundles may be made of nylon.

The both-side hair bundles and the space hair bundles may be made of polyester.

The both-side hair bundles and the space hair bundles may be made of polyolefin.

The both-side hair bundles and the interval hair bundles may be formed of natural hair.

[0025]

With the above-mentioned structure, the method of brushing the teeth can be carried out by the conventional bath method or the like. The double-sided bristles, which are long and have the same length of flocked hair, can come into contact with the boundary between the tooth and the gum by brushing the teeth, and this portion can be washed. In addition, the hair of the interstitial tufts formed between the tufts on both sides to be shorter than the tufts on both sides can clean the tooth surface portion. In addition, for both side bundles and interval bundles, nylon, polyester,
It can be formed of polyolefin, natural hair, or the like.

Further, the bristles of the spacing tuft provided with the same length as the both tufts of the tuft contact the groove between the teeth, and this portion can be washed.

As described above, since the bristles on both sides and the spacing bristles positioned at the bristling interval are formed such that the bristling length is partially lengthened or shortened in accordance with the shape of the teeth, the conventional toothbrush is not used. The boundary between the teeth and the gums that could not be contacted and the groove between the teeth can be cleaned by the conventional brushing method such as the bath method, and the plaque can be reliably removed.

The long and short flocks of the interval tufts are alternated between long tufts having the same tuft length as the tufts of both sides and short tufts of tufts shorter than the tufts on both sides. If formed into
The distance between the long tufts can be reduced, and even when a child with a small gap between the teeth and the tooth groove is used, the long tufts come into contact with this groove to ensure plaque It can be removed.

Further, the long and short flocks of the interval tufts form long tufts having the same tuft length as the tufts on both sides and short tufts of tufts shorter than the tufts on both sides. However, if you arrange two short tufts in the distance between the long tufts, you can increase the distance between the tufts between the long tufts. The long tufts come into contact with the groove of the tooth, and the plaque can be reliably removed.

The long and short tufts of the spacing tufts are formed by forming a pair of tufts having tapered tip portions and forming the long tufts of the same length as the tufts on both sides. If the short tufts are formed shorter than both sides of the tuft, the tapered tip of the tuft of the tuft can come into contact with the groove between the teeth and the boundary between the teeth and the gums, resulting in a great cleaning effect. Things are possible.

The long and short tufts of the spacing tufts are formed by forming a pair of tufts having tapered tip portions, and the tip of each tuft is flattened and tapered in the distance between the tufts of the tufts. If short short bristles that are shorter than long bristles are placed, the tapered tip of the interstitial bristles cleans the gaps between the teeth and between the teeth and the gums, and also shortens the short bundles. The flat tips of the bristles allow for extensive cleaning of the tooth surface.
