Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The disclosed technology relates to a technology of a toothless structure which has a toothpick function in a concave groove-shaped portion between molar teeth and tooth rows, exhibits a scouring action and a toothpick action, and can perform brushing. Belongs to the field.

[0002]

2. Description of the Related Art As is well known, as citizens' lives are improved, health and hygiene are being expanded to better conditions. Oral hygiene with
Along with this, toothpaste occupies an extremely important part, regardless of age or gender.

[0003] In particular, dentifrice in growing infants and children is regarded as an important insurance and hygiene item in daily life in the process of promoting growth as well as preventive and therapeutic measures, and dentifrice in middle-aged and elderly people retains its function. As a matter of interest,
It is also considered a health maintenance issue.

[0004] Therefore, toothbrushing directly involved in such dentifrices has been extremely old in history and has been regarded as extremely important, and the east and west of the ocean has been considered in view of the huge quantity of various types used between the ports. Regardless, it is indispensable for healthy civil life.

[0005]

The general structure of the toothbrush which has been conventionally used is, for example, a so-called bayonet type toothbrush 1 as shown in FIG. Invented in Japanese Patent Application Laid-Open No. 58-93230;
Even in the case of a tapered straight-type toothbrush 1 'as shown in FIG. 9 disclosed in the invention of Japanese Patent Publication No. 5-205, a group of brushes 2, 2 planted on one surface of a hanger 4' at the tip thereof. ′, As shown in FIG. 10, the occlusal surface having a relatively high incidence of tooth decay should be formed in a vertical plane with respect to the concave molar 3.
Regardless of the down-slope shape, the horizontal arrangement of each brush tip of each of the hanging brush groups 2, 2 'is generally flat, and
The tips of the hairs 21, 21 'of the book are also flat or hemispherical as shown in FIGS. 11 and 12 (although some are spherical), and as shown in FIGS. Spots such as 5 pits and fissures of the posterior teeth 3 that are likely to occur frequently do not fit reliably, and the tooth brushing effect on the pits and fissures 5 can be obtained unless brushing is performed in the lateral direction when brushing. Therefore, when brushing the teeth of infants, children, etc., the toothbrushes 1 and 1 'handles 4 and the hangers 41 at the tips thereof are not provided.
Must be given a lateral turning motion in the longitudinal direction, and the brushing of the posterior teeth 3 in the back direction is most difficult as an operation.

[0006] This point is substantially the same as the massage effect on the gingiva in the part where the 6-year-old molars are formed, and also at the boundary with the molars and between the dentition. The disadvantage is that the effect is not as high as expected.

On the other hand, a so-called circular tooth brush and a rake-type tooth brush for further improving longitudinal brushing have been developed in part to increase brushing in all directions by a plane brushing effect and are commercially available. However, a special polishing method has to be used, and there is a problem that widespread use has not been obtained due to poor usability or high cost.

[0008] Further, for example, a group of hanging brushes as disclosed in Japanese Utility Model Laid-Open No. 52-115370 and Japanese Utility Model Laid-Open No. 55-16712 is formed and implanted in a cross-sectional direction in a mountain shape. However, when brushing with the teeth in the oral cavity, the valleys of the concave parts that need to be brushed against the upper and lower teeth on the front side are contacted by a group of mountain-shaped brushes. Also, since the hanging brush groups on both sides are simply arranged in a chevron, the inclination angles of the chevron are the same in the left and right, so that the front of the chevron is difficult to face the valley 5 such as the pit or fissure of the molar, Has a long ridge line, and a toothpick-like brushing action cannot be performed, and it is difficult to reliably perform a preferable brushing action.

[0009] Thus, it is common practice for each other to know on a daily basis, however, it is customary to use a toothpick after eating, and the brush must be cleaned prior to brushing with a toothbrush. It eliminates food residues between the middle and the dentition, prevents tooth decay by itself, and makes the brushing of the dentifrice in the subsequent stage more effective.

[0010] Especially in middle-aged people, such habits are even necessary after meals, and even if they are not used, they may even cause discomfort.

However, such toothpick use is usually poor in appearance, and is accompanied by a feeling of resistance in adolescents and women.

Since the toothpick is made of wood or resin,
The danger was not negligible, so oral hygiene had the downside of brushing teeth.

To cope with this, a so-called toothpick or the like has been developed and used, but its shape is not convenient.
There was an inconvenience that there was no generality due to complicated workability.

[0014]

SUMMARY OF THE INVENTION The purpose of the invention of this application is to solve the problem of tooth brushing which is not suitable for the dental treatment, oral hygiene and insurance based on the above-mentioned prior art. And, between the dentition most likely to lead to the occurrence of caries, and, of course, the teeth themselves, residue removal by brushing gums, plaque removal from the physiological side,
Natural and reliable brushing can be performed even on molars that tend to have tooth decay, and the removal of food can be effectively performed between dentition and gums, suppressing the occurrence of tooth decay and sufficient for oral hygiene It is intended to provide an excellent toothpaste structure that contributes to the health technology application field in the health technology industry.

[0015]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the configuration of the invention of this application, which has the above-mentioned object as a utility model registration claim, has been proposed in order to solve the above-mentioned problems. When brushing the molars of the
In addition, when removing residue between teeth and removing plaque,
At the tip of the hanging brush group planted on the hanging table at the end of the handle of a predetermined length, at least one of the brush groups should be protruded longer than the other brush groups, and the strength should be slightly increased. In the general part, in a lateral arrangement, the ridges are formed in a mountain shape with a downward slope to the left and right along the valleys of the mortar. Molar teeth are cut at an acute angle of inclination, such as along the downhill inclination angle, and are effectively sewn, lifted and lifted effectively only by moving the front and back and left and right with respect to the axial direction of the toothbrush handle used by infants and middle-aged people. Valleys such as pit fissures,
In addition, brushing of each brush tip and removal of residue can be performed effectively, as well as the entire brush group on the side portions, between teeth, and gums. And technical measures that ensured that the occurrence of dental caries could be effectively prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the invention of the present application will be described below with reference to FIGS. It is to be noted that the same parts as those shown in FIG.

In the embodiment shown in FIG. 1, reference numeral 1 """designates a toothbrush which forms the center of the gist of the invention of the present application, and a predetermined pattern 4 made of a synthetic resin or the like is a block portion at an intermediate portion. 6, the front side 4 ″ is thick and the front side 4 ′ is thin, so that it can be easily gripped. It is bent so as to be elastically flexible at the tip, and a flock made of resin or the like forming the hanging brush group 2 ″ is placed on the hanging table 41 of a predetermined size at the tip of the bent part. As shown in FIG. 3, the groups are arranged in order in the front-rear direction (axial direction) in three lateral rows.

Thus, the hanging brush group 2 '' is implanted on the hanging table 41 in the same manner as in the conventional mode.
As shown in FIG. 5, in the cross section in the transverse direction of the three rows of flocking groups, they are formed in a mountain shape with an inclination angle α, and the brush 2 at the tip end
1 has a toothpick function by making one or a few of them protrude considerably longer than the other brushes, and has a slightly larger strength in the design and has a longer length. The toothpick action is made rigid, and the brushing action can be performed by bending.

Further, the flocking group has a shape as viewed from the front, as shown in FIG.
As shown in FIG. 3, the tips 2 and 21 'of each of the implanted hairs are also sharply beveled at the tips 2, 21', and the tip brushes 21 'are formed in the shape of a pointed knife and in the shape of a knife edge. It is formed in a shape that follows the part and the pit fissure 5, and the toothpick is easily scraped and massaged like a toothpick between the teeth, and the entire brush 2 ″ group is also shown in FIG. As shown in FIG. 6, it is formed in a chevron shape with one mountain in front view, and completely removes food residues in the pit and fissure 5 and plaque on the side of the tooth in accordance with the cusp inclination angle of the occlusal surface of the molar 3. It is possible to do.

Since the brush 21 at the tip is formed in a pointed shape, the action of removing the food residue from between the teeth is sufficiently effectively performed by the toothpick function.

Therefore, in general, when the infant or child grips the handle 4 and moves it back and forth in the dentition direction, it is usually possible to use both the initial fitting posture and the brushing operation.
The brush group 2 ″ can naturally be pressed down with an average toothbrushing force following the entire valley of the molar 3, and even during the brushing operation in the forward and backward movements, the central flocking group and the left and right chevron Each hair tip 21 ', 2 as well as the flocking group
1 ″ is also protruded in the shape of a valley or fissure 5 of the posterior teeth 3 so as to be able to perform a reliable brushing action over the entire surface, and one bristle of the brush group 2 ″ 21 ', 2
Since it is formed in a 1 ″ pointed protruding shape, it can be reliably brought into contact with the valleys of the posterior teeth such as the posterior teeth 3 and the like. The brushing action ensures that the tooth teeth 3 can be brushed, and the toothpick function of brushing by the protruding brushes 21 ', 21''at the pit fissures 5, between the teeth, and at the boundary between the teeth and the gums. It is possible to achieve a cleaning action, a residue removing action, and a plaque removing action.

In this case, depending on the manufacturing design, it is possible to adopt a mode in which the protruding brush 21 'at the tip has only one brush having an appropriate thickness and strength which is slightly larger. Is prevented from occurring due to

Of course, at the tip of the handle 4 and at the corner of the hanging table 41, a round portion, a round portion, etc. are formed in order to avoid the occurrence of inflammation or the like during brushing in the oral cavity, or a flexible material is appropriately formed. Needless to say, the lining can be formed.

In the above-mentioned configuration, when the infant or middle-aged or elderly person brushes the tooth after eating, etc., the handle 4 is gripped and the brush group 2 ″ at the tip of the handle 4 is inserted into the oral cavity. '' Naturally follows the dentition automatically, and is positioned particularly along the valley of the posterior molar 3, and the protruding brush 21 at the tip is longer than the other brush groups and has a relatively large strength. When the brushing operation is performed, the long brush 21 forcibly removes food residues between the pits and fissures 5 and the teeth through the toothpick action. Exterminate, and
Remove plaque.

Since the strength is slightly higher than that of the other brush groups, even if brushing is performed frequently, the function can be maintained without causing any variation.

When the handle 4 is moved back and forth by a natural motion, a steeply sloped left and right slope at the tip of the brush-shaped brush group 2 ″ along the valley of the molar 3. The tip edge of each bristle tip is aligned with the cusp inclination angle of the occlusal surface of the tooth and securely contacts the pit fissures 5 and the like, and between the teeth and at the boundary between the teeth and the gums. Gives a natural brushing action and massage action, and also gives a toothpick action, and removes food residues and plaque by scouring action without giving a special rotation action, effective toothpaste Is performed.

Therefore, the toothpick action can be performed simultaneously with toothbrushing without removing food residues using a toothpick prior to toothbrushing, as in the prior art.

Of course, it is possible to freely make the long tooth 21 protrudingly consciously face the pit fissure 5 or between the tooth rows to perform the toothpick action.

It should be noted that the brushing of the side of the molar 3 and the side of the other dentition need not be specifically instructed, and the toothbrush 1 "" is held sideways as in the conventional dentifrice. By brushing, each of the above brushing is performed more effectively.

During normal brushing, the protruding brush 21 is bent and assumes a laid-down posture, so that it can be performed without any trouble. Since the strength and rigidity are slightly higher than those of the group, extermination of food residues can be surely performed.

Further, it is needless to say that the brushing of the front teeth in the vertical direction can also be performed with the same holding posture as in the conventional mode.

Since the toothpick action can be performed during tooth brushing, it is possible to sufficiently cope with the fact that a woman or the like has a resistance to using a toothpick before tooth brushing.

Further, the pointed brush having a spot-like toothpick function has a somewhat higher strength and rigidity than other brush groups, so that its function does not occur even when repeatedly used, and its function is sufficient. Will be maintained.

It should be noted that the embodiment of the invention of this application is not limited to the above-described embodiment. For example, a protruding brush is implanted not only at the front end of the hanging table but also at the center or base. Various modes, such as rubbing, can be adopted.

Further, it is needless to say that two or more protruding brushes can be formed into a bundle in design change.

The present invention can be applied not only to manual toothpaste but also to electric toothpaste, so-called "instant toothpaste" and "good-bye toothpaste" used in hotels, inns and the like. Of course, the present invention can be applied to disposable toothpastes such as "".

It is needless to say that the usage guidance can be performed in the same manner as in the conventional mode, regardless of the age of the infant, the elderly, etc., and the gender.

[0038]

As described above, according to the invention of this application, when brushing teeth by brushing the teeth, basically, the brush group which is planted on the hanging table at the tip of the handle of the brush as a whole. Since it is formed in a cross-sectional mountain shape in the lateral direction, just by inserting a toothbrush into the oral cavity against a molar, etc., the tip automatically sharpens automatically into the pit or fissure such as the valley of the molar. The flocking group that has been beveled into can fit into the mountain shape and adhere to it with an average force over the entire surface of the valley.
Simply, the brushing of the posterior teeth etc. can be performed more reliably as expected by the scrubbing action, there is no need to give a rotary brushing even in a circular posture etc. in an unreasonable posture, the tooth brushing effect is promoted, especially the length of the brush group In a mode in which the left and right gradients are formed at a steep angle at the leading end, the abutment posture of the posterior posterior teeth against the pit and fissure is reliably revealed, the cleaning action by brushing is promoted, and The protruding, long and strong brush has a point-intensive action on the toothpick compared with the other brush groups at the tip of the ladder, and is especially powerful at the same time as toothpaste without using a toothpick prior to toothpaste. It eliminates food residues, ensures the removal of plaque, maintains its function without repetition even in repeated use,
In addition to preventing the occurrence of tooth decay, an excellent effect of preventing tooth decay at an early stage and imparting a massage effect to gums can be obtained.

The brush tips of each brush are formed so as to be inclined at an angle in accordance with the inclination angle of the left and right brush groups. An excellent effect that the brushing can be performed on the portion is achieved.

Further, since the hanging brush groups are formed in a chevron arrangement in a transverse cross section, when brushing the side surfaces of the molars and other dentition, the tips of the flocking of each hanging brush group are replaced with other bristle brushes. Brush cleaning can be performed more reliably than the group, and especially, brushing in the mountainous part where the left and right slopes are large with respect to the back teeth etc. The toothpick effect is promoted, and the effect of being able to perform effective tooth brushing as expected without performing dexterous operation is achieved.

Thus, by simply inserting the handle in the direction along the dentition when the dentifrice is brought into the oral cavity, the set of dentifrice brushes and the tip of each tress are naturally set. In order to be in a posture along the valleys of the molar teeth, etc., if it is inserted and moved back and forth, the toothbrushing action will be assured, in addition to the lifting action without using a toothpick before toothbrushing. Can be effectively performed at the time of tooth brushing, and it has the effect of reliably removing pit fissures and food residues between teeth. Especially, natural tooth brushing operation without special instruction for infants and elderly people It has the effect of being able to perform a reliable and good tooth brushing and toothpick action, and has a great benefit to contribute to oral health and hygiene.

Such an effect can be used without a feeling of resistance for women and the like.

In addition, when the use for infants is encouraged, even before the replacement of the 6-year-old molars, the teeth can be brushed naturally in a posture that is familiar to the growing molars and the like, especially without any guidance. As a result, in the present condition of a 6-year-old molar, it has the effect of preventing the problem of being already decayed by tooth decay and the like. There is an advantage that toothpick action and brushing on gums and between teeth and gingiva can be effectively performed by the arrangement of the flocking group.
