Description

  The present invention relates to a tooth brushing device for improving a dirt removing function.

  In a conventional toothbrush, a rod-shaped grip member is formed of hard resin, and a brush is implanted in a head portion of the tip. In some cases, in order to improve the function of removing dirt from the tooth surface of the toothbrush, a part of the distal end head can be elastically moved in accordance with the brushing force. This type of toothbrush is described, for example, in Patent Document 1.

JP-A-2002-51838

  However, in the conventional toothbrush, since the tooth surface is polished with the brush at the tip, it is difficult for the tip of the brush to come into fine contact with the surface of the tooth, and the dirt that has entered the minute uneven surface of the tooth surface cannot be completely removed. There is a problem.

  The present invention is intended to solve such a conventional problem, and makes it possible to finely contact a tooth surface with a fine grain to scrape dirt that has entered fine irregularities on the tooth surface, and to remove dirt from the tooth surface. An object of the present invention is to provide a tooth brushing device that significantly improves its function.

  In order to solve the above-mentioned problems, a tooth brushing device of the present invention includes a grip member and a brush member, and the brush member is formed of a resin foam molded body mainly composed of melamine resin, and has a fine mesh-like shape as a whole. The gist of the present invention is to have fine fluff of the melamine resin on a contact surface with a tooth. In this case, the brush member can be constituted by a single or a plurality of blocks. Further, the contact surface of the brush member with the teeth may be formed substantially flat or may be formed non-flat. Further, the brush member may be detachably attached to the tip of the grip member. In the case of a detachable brush member, it is preferable that the grip member is provided with a storage portion for the brush member, and a replacement brush member is stored in the storage portion.

  The tooth brushing device of the present invention has the above-mentioned configuration, and a brush member made of a foamed melamine resin molded article mainly made of hard melamine resin is applied to a tooth surface and brushed by the same brushing method as a normal toothbrush. The fine fluff of the hard melamine resin on the surface of the brush member comes into fine contact with the tooth surface, so that dirt that has entered the fine uneven surface of the tooth surface can be scraped off, and the dirt removing function for the tooth surface can be removed. Can be greatly improved.

  Hereinafter, first to fourth embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment of the present invention. In FIG. 1, a tooth brushing device 1 (hereinafter simply referred to as a brushing device 1) includes a grip member 2 and a brush member 6, and is configured in a general toothbrush shape as a whole. The grip member 2 is entirely formed into a substantially rod shape with a resin such as polypropylene, and has a grip 3 on the base end side and a head 4 on the tip end. A substantially rectangular or substantially elliptical concave portion 5 is provided. The fixing portion of the brush member 6 may be provided in the form of a substantially rectangular or substantially elliptical frame instead of the concave portion 5. The brush member 6 is made of a resin foam molded product mainly composed of a hard melamine resin, has an extremely fine mesh-like structure as a whole, and has a very fine (melamine resin) fluff 7 on a contact surface with teeth. . This melamine resin foam molded body is formed by mixing foaming raw materials with melamine and formaldehyde as main raw materials, heating, foaming and molding, and hard melamine resin is formed into a single rectangular parallelepiped block with elasticity and flexibility. That is, the contact surface of the resin foam molded body with the teeth (the aggregate of the melamine resin fluff 7) is formed substantially flat. Although not described in detail here, it goes without saying that a material suitable for the oral cavity or the human body is used or processed for the brush member 6. The brush member 6 thus formed has a lower end fitted into the concave portion 5 at the tip of the grip member 2 and an upper side protruding from the front surface of the head 4. In this case, the brush member 6 and the recess 5 may be fixed by press-fitting the brush member 6 into the recess 5 by making the plane area of the recess 5 of the head 4 smaller than the plane area of the brush member 6, Alternatively, the brush member 6 and the concave portion 5 may be fixed using fixing means such as an adhesive. Further, even if the fixing portion of the brush member 6 is formed as a substantially rectangular or substantially elliptical frame as described above, the brush member 6 can be attached in the same manner.

  This brushing device 1 is used as follows. The brushing with the brushing device 1 may be performed supplementarily or as needed, separately from brushing with a general toothbrush, and brushing is performed once a week, and need not be performed every day. In use, first, a suitable amount of water is contained in the brush member 6 of the resin foam molded article. There is no need to brush this brush member 6. Then, the brush member 6 may be applied to the tooth surface and brushing may be performed by a brushing method substantially the same as that of a general toothbrush. In this case, light brushing may be sufficient, and strong brushing that damages tooth enamel and gums is not preferable. The brush member 6 of the resin foam molded body comes into contact with the tooth surface with a soft touch due to its elasticity and flexibility, and the other side, the fluff 7 of the hard melamine resin of the resin foam molded body finely contacts the tooth surface. As the brush member 6 moves, dirt that has entered the extremely fine uneven surface of the tooth surface is effectively scraped off. The dirt is absorbed into the inside (gap) of the brush member 6 of the resin foam molded body. While the brushing device 1 is used, the brush member 6 may be shaved. In such a case, the shavings may be discharged from the mouth and never swallowed.

  As described above, according to the first embodiment, the brush member 6 of the brushing device 1 is formed of a melamine resin foam molded body, and the entire structure is formed into a fine mesh structure, and the melamine resin The extremely fine fluff 7 is provided, and the fluff 7 of the melanin resin is finely brought into contact with the tooth surface with a normal toothbrush brushing method, and the dirt that has entered the extremely fine uneven surface of the tooth surface is scraped off with the fluff 7. Therefore, the yellowing of the teeth can be removed and the teeth can be whitened, so that the function of removing dirt on the tooth surface can be significantly improved.

  FIG. 2 shows a second embodiment of the present invention. This embodiment is different from the first embodiment in that the upper surface of the brush member 6 and the contact surface with the teeth are formed non-flat, and the other parts are the same as the first embodiment. Only the points will be described, and common portions will be denoted by the same reference numerals as in the first embodiment, and redundant description will be omitted. In FIG. 2, the brush member 6 of the resin foam molded body has a tooth contact surface formed in a sawtooth shape. In this case, the sawtooth shape may be formed on the entire contact surface, or may be formed on a part of the contact surface. In this way, the pointed portion of the contact surface with the teeth is easily inserted between the teeth, and the fluff 7 of the hard melamine resin comes into fine contact with the both side edges of the teeth. The dirt that has entered the very fine uneven surface of the edge surface is effectively scraped off, and the dirt is absorbed into the inside (gap) of the brush member 6 of the resin foam molded article. Even in this case, it is used in the same manner as in the first embodiment, the same operation and effect as in the first embodiment can be obtained, and further, the stains on both side edges of the teeth can be effectively removed.

  FIG. 3 shows a third embodiment of the present invention. In this embodiment, the grip member 2 is configured such that the concave portion (or frame) of the head 4 is a plurality of small concave portions 53 (or frames), and the resin foam molded body of the brush member 6 is formed by a plurality of small rectangular parallelepiped blocks 63. The configuration is different from the first embodiment, and the other parts are the same as the first embodiment. Therefore, only the different points will be described, and the common parts will be denoted by the same reference numerals as those of the first embodiment. The same description is omitted here. In FIG. 3, a plurality of small concave portions 53 are provided on the front surface of the head 4. The planar shape of these concave portions 53 may be a polygon such as a rectangle or a square, or may be a circle or an ellipse. Note that, as described above, these concave portions 53 may be replaced by frames having a substantially rectangular or elliptical planar shape. Each block 63 of the resin foam molded body of the brush member 6 is formed in a polygonal shape such as a rectangle or a square, or a columnar shape in a circle or an ellipse. The lower ends of these blocks 63 are fitted into the respective recesses 53 (or frames) at the tip of the grip member 2, and the upper sides thereof protrude from the front surface of the head 4. In this case, the plane area of the recess of the head 4 may be made smaller than the plane area of each block 63, and each block 63 may be fixed by press-fitting into each recess 53 (or frame). 63 and each recess 53 (or frame) may be fixed using fixing means such as an adhesive. By doing so, the upper surface edge of each block 63 of the brush member 6 is easily inserted between the teeth, and the hard melamine resin fluff 7 of each block 63 comes into fine contact with both side edges of the teeth, With the operation of the brush member 6, the dirt that has entered the microscopic uneven surface of the edge surface is effectively scraped off, and the dirt is absorbed into the brush member 6 of the resin foam molded body (gap). Even in this case, it is used in the same manner as in the first embodiment, the same operation and effect as in the first embodiment can be obtained, and further, the stains on both side edges of the teeth can be effectively removed.

  FIG. 4 shows a fourth embodiment of the present invention. This embodiment is different from the first embodiment in that the brush member 6 is detachably attached to the tip of the grip member 2, and the other parts are the same as the first embodiment. Only the same parts will be denoted by the same reference numerals as in the first embodiment, and redundant description will be omitted. In FIG. 4, a concave portion 5 is formed in the distal end head 4 of the grip member 2. On the other hand, the brush member 6 of the resin foam molded body is a single rectangular parallelepiped block similarly to the first embodiment, and the holding member 8 is attached around the block, and is fitted into the concave portion 5 at the tip of the grip member 2. ing. Here, the holding member 8 is a functional component that protects or reinforces the brush member 6 and also fixes and holds the brush member 6 in the concave portion 5 at the tip of the grip member 2. The holding member 8 elastically holds the brush member 6 on the inner periphery thereof and is fitted into the concave portion 5 of the grip member 2. Even in this case, it is used in the same manner as in the first embodiment, and the same operation and effect as in the first embodiment can be obtained. In addition, the brush member 6 can be removed from the grip member 2 and replaced with another brush member 6 replacement piece, and the same grip member 2 can be used repeatedly. Can be provided.

  The first to fourth embodiments can be variously modified. First, in the fourth embodiment, a storage portion for a brush member replacement piece may be provided in the grip member 2, and the brush member replacement piece may be stored in this storage portion. In this case, by providing a recess, a hole, or a frame in which the brush member exchange piece can be fitted in the grip member as a storage portion, the brush member exchange piece can be inserted into the recess, hole, or frame. By providing a detachable case, the brush member replacement piece can be put in this case. In addition, this storage portion may be either one for storing one brush member replacement piece or plural for storing a plurality of brush member replacement pieces. Further, the brush member replacement piece may have a flat or non-flat contact surface with the teeth, or may be constituted by a plurality of small blocks. When the brush member replacement piece is configured by a plurality of small blocks, the holding member is formed in a plate shape that can be press-fitted into the recess at the tip of the grip member, and a plurality of holes or recesses for inserting and fixing each small block in the plane thereof. Adopt one with a frame. Further, the holding member may be repeatedly used as an accessory part on the grip member side, or may be provided integrally with the brush member replacement piece as a part on the brush member replacement piece side. In addition, the concave portion of the grip member may be replaced with a frame, and by providing an engaging member or a fixing member for the brush member replacement piece in this concave portion or frame, the brush member replacement piece can be directly used without using a holding member. You may make it attach to a recessed part or a frame. Further, the grip member may be formed in a cylindrical shape, a brush member may be loaded inside the grip member, and a part of the brush member may be protruded from the grip member. In this case, the brush member may be the same length as or longer than the grip member, and may be configured as a plurality of replacement pieces. In any case, the brush member is fixed at the open end of the grip member. It is preferable to provide a fixing means to perform the fixing.

  Further, in the first to third embodiments, the holding member 8 shown in the fourth embodiment is not provided around the brush member 6, but the brush member is provided in the same manner as in the fourth embodiment. You may provide a holding member and protect it. In this case, a holding member made of a synthetic resin may be integrally covered over a predetermined area on the lower side around the brush member so that the upper end of the brush member protrudes from the holding member. The leading end of the member may be formed to be raised in a frame shape or a cylindrical shape to protect the periphery of the brush member fixed to the head. By reinforcing the brush member in this manner, the brush member can be used for a long time.

  Further, in the first to fourth embodiments, the shape of the grip member 2 is arbitrary, and may be formed in a block shape, for example, in addition to a rod shape. Further, as a special form (fifth embodiment), the grip member may be formed in a finger-sack shape as shown in FIG. In this case, the brush member 6 of a melamine resin foam molded article can be attached to the tip or the outer peripheral surface of the middle (of the finger cot). This results in extremely excellent portability.

  Further, in each embodiment, the brush member 6 is formed in a block shape. However, the brush member may be formed in a thin flat shape or a thin protrusion shape, and further formed in a brush shape or a thread shape ( It may be fixed as in the prior art), and even if the shape is changed in this way, the same operation and effect can be obtained. In this case, the brush member may be made into a sheet shape, for example, to have a size necessary for one use, thereby making it a single-use type. Alternatively, a thin, fine, or thread-like brush member may be attached to a stick-like grip member to be used as an interdental brush. In addition, the brush member may be changed to a spherical shape, and the spherical brush member is sandwiched between the upper teeth and the lower teeth, and is used to bite and squeeze (that is, to squeeze in the manner of tooth squeezing). As a result, the brush member deforms and wraps around the back of the tooth, so that the back of the tooth can be polished cleanly. Further, the resin foam molded body of the brush member may be formed in a circular shape around the shaft member, a bearing may be provided at the head of the grip member, and the brush member may be rotatably attached to the grip member. By doing so, brushing can be performed while rolling the brush member on the tooth surface. Further, in each of the embodiments, the brush member 6 is used with water contained therein, but the brush member may contain an aftercare agent, for example, a peel extract. In this case, by covering the surface of the brush member with a net-like covering material, the medicine contained in the brush member can be held, and the medicine can permeate while brushing with the brush member.

  Further, in each of the embodiments, the melamine resin is used as the hard resin forming the brush member 3, but may be replaced with another resin material. In this case, a resin material having approximately the same polishing performance as a melamine resin is preferable.

  Further, in each of the embodiments, the entire brushing device 1 is formed in a toothbrush shape. However, a grip member of a dental treatment device may be used as a grip member, and a brush member may be detachably attached to the tip thereof. In this way, the same grip member can be used as a dental treatment instrument and also as a tooth brushing instrument. In addition, the grip member may be a dental technic appliance or a denture repair appliance grip member, and a brush member may be removably attached to the tip thereof. In this manner, the same grip member can be used as the dental technic appliance. Alternatively, it can be used together as a denture repair device and further as a tooth brushing device.
