Description
The present invention relates to a toothbrush.
The present application claims priority based on Japanese Patent Application No. 2011-267939, filed on Dec. 7, 2011, the contents of which are incorporated herein by reference.
A general toothbrush includes a handle body having a head portion with a hairline, a handle portion to be gripped at the time of use, and a neck portion to connect the head portion and the handle portion, and a knife portion having a hair- will be.
BACKGROUND ART [0002] In a toothbrush as a cleaning appliance in the oral cavity, a plurality of inventions have been made to enhance the cleaning effect, which is the most necessary function. In order to enhance the cleaning effect, it is important that the flocking portion is brought into contact with the portion to be cleaned, and the portion to be cleaned is rubbed with an appropriate brushing pressure. The plaque attached to the tooth surface, the occlusal surface of the molar, the moving tooth, and the cervical portion can not be sufficiently removed unless the flocking portion properly contacts the cleaning target portion. If the brushing pressure is too small when cleaning the inside of the mouth, it is difficult to drop the plaque, especially the plaque of the narrow portion such as the interdental portion or the cervical portion, and if the brushing pressure is too large, there is a risk of damaging the gums and the teeth.
It is common in toothbrushes to devise such arrangements as hair arrangement, shape of appearance, hair shaping of hair, and so on, so that the hair follicle comes into contact with the area to be cleaned appropriately.
In recent years, as the hygienic orientation has become higher, it is required to further improve the cleaning effect of the toothbrush. In order to meet such a demand, a toothbrush combined with a hair shaft having a different diameter and a hair shaft having a different hair- A toothbrush has been proposed.
In addition, an attempt has been made to improve the cleaning effect by the devising of the handle body.
For example, there has been proposed a brush having a round rectangular shape or an elliptical shape with a small numerical value with respect to the other side in the thickness direction of the bristles across the entire neck (see, for example, Patent Document 1 ). According to the invention of Patent Document 1, the neck portion is thinned so as to be bent lighter and lighter, thereby alleviating the brushing pressure.
Alternatively, a toothbrush has been proposed in which the contour of the thickest portion of the grasping portion that is touched by the thumb is a hexagonal shape of a specific shape (for example, Patent Document 2). According to the invention of Patent Document 2, by changing the face touching the hexagonal shape of the thumb of the holding hand, the angle formed by the boundary line between the teeth and the gums and the bit line of the toothbrush is determined, Cleaning is planned.
However, it is effective to thin the neck portion and improve the operability in the oral cavity in order to properly dope the flocked portion with respect to all the cleaning target portions such as the tooth surface of the molar, the occlusal surface, the tooth portion, and the cervical portion.
However, if the neck portion is made thinner and the operability of the toothbrush in the oral cavity is increased, the strength of the handle body is insufficient, and the amount of deflection of the neck portion becomes too large, and the cleaning effect tends to be deteriorated. It is possible to prevent the handle body from being bent or broken by molding a handle body using a resin having a high strength (a bending elastic modulus of 2000 MPa or more). However, since the bent amount of the neck portion can not be completely controlled, There is a problem that it is not possible to chase.
It is therefore an object of the present invention to provide a toothbrush having a high cleaning effect even when the neck portion is made thinner.
As a result of intensive studies, the inventors of the present invention have found that, by changing the cross-sectional contour of the neck portion to a specific shape from the head portion side toward the handle portion side and regulating the direction in which the neck portions are bent, It is possible to improve the cleaning effect by cleaning with an appropriate brushing pressure, and have reached the present invention.
In other words, one aspect of the toothbrush of the present invention is a toothbrush comprising: a head portion having a hair-tight groove; a neck portion extending from the head portion; and a handle portion extending from the neck portion, Wherein the neck portion has a substantially circular cross-sectional contour near the head portion, and as the outline contour of the substantially circular portion faces the handle portion, the cross- (Top) is located on both sides of the substantially quadrangular cross-sectional contour of the above-mentioned rectangular cross-section toward the handle portion, and is formed into a rough polygon that is flat in the thickness direction .
It is preferable that any one side of the rough polygon flat in the thickness direction is formed on the surface of the neck portion and a side opposite to the arbitrary one side is formed on the back side of the neck portion, To the handle portion.
That is, the present invention relates to the following.
(1) A headlight device comprising: a head portion that is hollow; a neck portion that is provided in the head portion; and a handle portion that is provided in the neck portion, wherein the neck portion has a cross-sectional outline that changes from the head portion side toward the handle portion side In a toothbrush,
Wherein the neck portion has a generally rectangular cross sectional profile on the side of the head portion and a substantially rectangular cross sectional profile formed on the front side, the back side and the side face as the outline contour of the substantially circular portion faces the handle portion side, And a substantially quadrilateral cross-sectional outline of the toothbrush is located on both sides of the handle so as to form a substantially polygonal shape flat in the thickness direction.
(2) The polygonal shape flattened in the thickness direction described above is characterized in that any one side is formed on the surface of the neck portion, and the opposite side to the arbitrary side is formed on the back side of the neck portion. ≪ / RTI >
(3) The toothbrush according to (1) or (2), wherein the neck portion is enlarged from the head portion side toward the handle portion side.
According to one aspect of the toothbrush of the present invention, the neck portion has a generally circular cross-sectional contour on the side of the head portion, and the cross-sectional contour of the substantially circular cross- Sectional shape and the outline contour of the substantially quadrangular shape as described above is directed toward the handle portion side, the corner portion is located on both sides and is formed into a roughly polygonal shape flat in the thickness direction. Therefore, even if the neck portion is made thinner, .
According to an aspect of the toothbrush of the present invention, the above-mentioned roughly polygonal shape flat in the thickness direction is formed by a certain one side on the surface of the neck portion, and the side opposite to any one side is formed on the back surface of the neck portion , It is possible to further reduce the brushing pressure.
According to one aspect of the toothbrush of the present invention, since the neck portion is enlarged from the side of the head portion toward the side of the handle portion, the neck portion is bent more lighter and lighter and the brushing pressure can be made more appropriate.
