Description

The present invention relates to a tool for removing stains (color stains) adhering to the surface of teeth.

Stain, which is a discoloration of teeth, is a nuisance that gradually adheres to teeth over a long period of time and causes yellowing and dullness, even if one does not miss daily toothbrushing. Polyphenols, which are relatively abundant in foods such as curry, chocolate, and coffee, combine with a protein called pellicle, which covers the enamel of teeth, to form stains. Since this stain does not dissolve in water, it cannot be easily removed with a mouthwash. In recent years, cigarette lovers have decreased, but this tar becomes an extremely stubborn stain.

Stain is not only difficult to remove even with daily toothbrushing, but it also causes yellowing and dullness over a long period of time. Although separate stain care is required, there has been no effective remover until now. In view of such circumstances, the present inventor previously disclosed “an oral cleaner with a polishing portion” in Japanese Patent Application Laid-Open No. 2017-217438.

This toothbrush consists of a handle 1 made of polyester resin and a head 10 having a nylon brush 11 implanted therein. is a toothbrush. The brush 11 is used for normal tooth brushing, but when removing stains from the surface of the tooth, the polishing portion 2 of melamine foam is used to rub the surface of the tooth. As a result, dirt such as stains and biofilms can be removed at the same time as toothbrushing.

Although this has the desired effect, there is a difference in life between the nylon brush 11 and the melamine foam polishing portion 2, and the polishing portion 2 is damaged first. In addition, the nylon brush 11 and the melamine foam abrasive part 2 make the head of the toothbrush large, which sometimes makes children and women feel uncomfortable. Or it may not fit in a portable case when traveling. If these are problems, I would like to solve any one or, if possible, all of them.

The above problem is a remover for removing stains adhering to the surface of teeth, which is formed by laminating an adhesive part and release paper covering the surface of the adhesive part on melamine foam formed so as to be able to contact the teeth. This is achieved by To be able to contact with the teeth means that the surface of the melamine foam is flat or curved along the curved surfaces of the teeth. Even if it has a planar shape, it may elastically deform to fit the shape of the tooth when it is brought into contact with the tooth.

In this usage, the surface of the adhesive part that appears when the release paper is peeled off is attached to, for example, the tip of the index finger, then the index finger is inserted into the mouth and the melamine foam is pressed against the surface of the tooth to rub the stain. I will try to take it. At this time, it is good to rub between the gums and between the teeth. Alternatively, as described above, it is also good to form a shape part that fits there in melamine foam. The effects of melamine foam will be described later.

Alternatively, the surface of the adhesive portion that appears when the release paper is peeled off may be adhered to a handle similar to the handle of a toothbrush. Manipulate the handle to press the melamine foam against the tooth surface to scrape off the stain.

If you have a large oral cavity, you can use the melamine foam by adhering it to the back of the brush or the handle of the toothbrush with the surface of the adhesive part that appears when the release paper is peeled off. In any case, the melamine foam of the present invention may be used only once, or it may be replaced with a new one when it is worn out. The reason why this is possible is that the melamine foam is laminated with an adhesive part and a release paper covering the surface of the adhesive part.

For convenience of carrying, etc., a cap covering the melamine foam may be provided separately, or the handle may be configured to be foldable in two, and a cap capable of covering the foam when folded in two may be provided on the handle. .

Melamine foam (melamine resin foam) has the action and effect of an abrasive and does not require the use of detergents, and is used for removing stains from tableware, kitchen counters, bathrooms, and the like. It was a great progress that this was brought to fruition in Japanese Unexamined Patent Application Publication No. 2017-217438, “Oral Cleaner with Polishing Portion”. As a result of research, it has been found that tobacco tar and tea stains adhering to the surface of tooth enamel can be removed well.

In this invention, since the tooth stain remover is made by laminating an adhesive part and release paper covering the surface of the adhesive part on the melamine foam, it is used by sticking a finger to something like a handle. I became able to do it. Such tooth stain removers can be disposable. Alternatively, it is possible to appropriately replace the melamine foam with a new one based on the state of wear of the melamine foam. Hygiene effects are also seen.

Embodiments of the invention will be described below with reference to FIGS. 1 to 6, but the invention is not limited to these.

FIG. 1(A) shows a melamine foam having a rectangular surface portion 10 and corner portions 11 formed by forming grooves around the side surface, that is, a melamine resin foam on the opposite side of the surface portion 10. This tooth stain remover 1 is provided with an adhesive layer 3 and a peelable release paper 4 so as to cover the surface of the adhesive layer 3. - 特許庁

In addition, FIG. 1B shows an adhesive layer 3 provided on the opposite side of the surface portion 20 of the melamine foam provided with the interdental contact portion 21 by shaping the square surface portion 20 in a wave shape, and this adhesive layer The stain remover 2 for teeth includes a release paper 4 releasably provided so as to cover the surface of the tooth 3.

The tooth stain remover 1 and the tooth stain remover 2 have different appearances. In either case, in this embodiment, a plurality of pieces are packaged together and sold.

FIG. 2 is an example of use of the tooth stain remover 2 of FIG. 1(B). The back of the index finger F was adhered with the adhesive layer 3 which appeared when the release paper 4 on the back surface was peeled off. In this state, when the finger is rubbed vertically and horizontally on the surface of the tooth, dirt on the tooth can be scraped off with the entire surface portion 20 of the melamine foam. Alternatively, when the surface part 20 is fitted to the teeth, the interdental contact part 21 is positioned between the teeth, so if the finger is shaken finely in this state, the interdental contact part 21 rubs the dirt between the teeth. can take

Next, the wooden handle H is made for the tooth stain removers 1 and 2, and the tooth stain remover 1 is adhered to the tip of the handle H in FIG. That is, the adhesive layer 3 that appears when the release paper 4 on the back of the tooth stain remover 1 is peeled off was adhered to the tip of the handle H. As shown in FIG. In this state, the handle H can be manipulated like a toothbrush to scrape off stains on the teeth. Square corners including corners 11 can be used between teeth.

FIG. 4 shows an example of use of the tooth stain remover 1 of FIG. 1(A). A tooth stain remover 1 was adhered to the dorsal side of a brush portion B of a commercially available toothbrush TB with an adhesive layer 3 appearing when a release paper 4 on the back surface was peeled off. In this state, it is possible to use the dirt removing function of the melamine foam while brushing the teeth. Although the use example of FIG. 4 seems to go against the gist of the present invention, the tooth stain remover 1 can be peeled off if unnecessary, and such an example of use is also possible. .

FIG. 5 is constructed so that the above-described handle H can be folded in two, and the tooth stain removers 1 and 2 are covered with caps when the handle H is folded in two. The whole is made of synthetic resin, and the first handle portion 5 and the second handle portion 51 are configured to be rotatable on a rotating shaft 53 . The adhesive bed 50 provided at the tip of the first handle 5 side is a part to which the tooth stain removers 1 and 2 are attached, and is a cap for covering the tooth stain removers 1 and 2 when folded in two. A portion 52 is provided on the second handle portion 51 side.

This can be used like a toothbrush when it is opened from a folded state and the first handle 5 and the second handle 51 are straightened. At this time, the tooth stain removers 1 and 2 are adhered to the adhesive bed 50 of the first handle 5 with the adhesive layer 3 exposed when the release paper 4 is peeled off.

After use, cleanly wash both the tooth stain removers 1 and 2, and then fold the first handle 5 and the second handle 51 in two so that they can be folded compactly. By covering the parts of the tooth stain removers 1 and 2, the tooth stain removers 1 and 2 can be kept clean.

Whether it is the finger F described above, the handle H, the commercially available toothbrush TB or the tooth stain removers 1, 2, the stain removers 1, 2 can be disposable. The melamine foam can be peeled off from the adhesive layer 3 by applying force. Alternatively, it is possible to replace the dirt removers 1 and 2 with new dirt removers 1 and 2 by judging the degree of dirt on the melamine foam. This point is also an advantage of the present invention.

There is industrial applicability in further enhancing the invention of the "oral cleaner with a polishing portion" of JP-A-2017-217438 of this invention. The present invention can be provided for caring the teeth of pets such as dogs and cats. This is also within the scope of the invention.
