Description

TECHNICAL FIELD [0001] The present invention relates to a pressurizing transferring chamber for a cosmetic tooth of a tooth,

The present invention relates to a cosmetic pressure transferring apparatus for a tooth to which a wax layer and a pressure-sensitive adhesive layer are adhered and transferred to a tooth surface by peeling a support after pressurization with a pressure-sensitive adhesive layer surface attached to a tooth surface, transfer seals. More specifically, the present invention relates to a cosmetic pressurizing apparatus which has a proper adhesive force necessary for achieving both simplicity and operability and a peeling force from a support, and which can impart a good color tone to a tooth without being stained (cosmetic effect) Transferring chambers and a method of making a tooth surface using the transferring chamber.

A number of coating compositions using a water-insoluble film-forming agent have been proposed as a formulation capable of temporarily changing the color tone of teeth to a cosmetic sensation (Japanese Patent Application Laid-Open No. 4-82821, Japanese Patent Application Laid- 8-325128, Patent Document 3, and JP-A-9-100215). However, even if the surface of the tooth surface is sufficiently removed before application, especially in the lower jaw, these coating compositions are wetted again with the saliva during application, so that it is difficult to apply them without staining.

On the other hand, an example of attaching a dry film composition to a tooth has been proposed (refer to Patent Document 4; Japanese Patent Publication No. 2003-526648, Patent Document 5; Japanese Patent Specification No. 2006-516654) In such a case, if the entire tooth is not covered completely, the contrast of the portion not attached with the film composition is enlarged, and the unnaturalness may be emphasized in reverse. Further, since the dry film composition is broken, wrinkled, or fragile when being put, it is also difficult to adhere to the teeth.

In order to solve these problems, there is a method of delicately cutting a film in accordance with the size of another tooth, but it requires a great deal of time and effort, has problems in operability and simplicity, and is cumbersome and less practical.

When the pH exceeds 10.0, mucous membrane peeling may occur due to contact with the gums and the like.

Examples of the pH adjusting agent include acetic acid, hydrochloric acid, sulfuric acid, nitric acid, citric acid, phosphoric acid, sodium hydroxide, potassium hydroxide, sodium acetate, sodium carbonate, sodium citrate, sodium citrate, sodium phosphate, sodium hydrogenphosphate, 1-ol, 2-amino-2-methylpropane-1,3-diol and the like.

The pressure sensitive transfer transferring chamber of the present invention can be obtained by rubbing wax on the silicone-coated surface of a support or by immersing the support in a wax solution and spreading the wax layer to form a wax layer, , A solution of a pressure-sensitive adhesive composition in which a pressure sensitive adhesive component and a plasticizer are added to a volatile solvent such as ethanol, and a white pigment or a thickening agent is added and dispersed as required (hereinafter referred to as a prior solution) is dried to form a volatile solvent To form a pressure-sensitive adhesive layer.

In the present invention, the thickness of the layer (transfer layer) including the wax layer and the pressure-sensitive adhesive layer is preferably 10 to 200 占 퐉, and more preferably 20 to 100 占 퐉. When the thickness of the transfer layer is less than 10 mu m, the physical strength of the pressure transferring chamber for cosmetic use of the teeth is too weak, so that the durability is lowered and a sufficient cosmetic effect can not be obtained. If added, the adhesive strength and durability may be further deteriorated. If the thickness is more than 200 mu m, durability may be deteriorated because not only there is a sense of discomfort at the time of attachment but also contact of the lips is increased.

The thickness of the pressure-sensitive adhesive layer is not particularly limited as far as the adhesive force is exerted on the teeth. However, the thickness of the pressure-sensitive adhesive layer is preferably 10 to 200 占 퐉, more preferably 20 to 100 占 퐉 because the wax layer is very thin It is preferable that the leading solution is preliminarily so that the range is appropriate and the thickness is within this range. The thickness of the wax layer is preferably from 0.1 to 70 mu m, particularly preferably from 1 to 35 mu m.

After the lead solution of the pressure-sensitive adhesive composition is allowed to stand, it can be dried by removing the volatile solvent by standing at 20 to 95 캜 for 1 minute to 24 hours.

In the present invention, the surface of the pressure-sensitive adhesive layer of the cosmetic pressure transferring chamber is adhered to the tooth surface, the support is peeled off, and the wax layer and the pressure-sensitive adhesive layer are adhered to the tooth surface to be transferred. And in particular, the transfer layer containing white pigment is transferred to the tooth surface, so that a more natural and uncomfortable color tone can be imparted.

The cosmetic pressure transferring chamber of the tooth of the present invention can be transferred not only to one surface of each tooth, but also to a plurality of tooth surfaces at the same time. In addition, it is also possible to improve the transferability by being used in combination with a tool to be brought into close contact with a tooth portion or the like. Examples of the method of pressurizing and transferring the pressure transferring chamber to the tooth surface include not only pressing with a finger but also a method of rubbing on a smooth surface or a tooth portion of a tooth with a stick or the like.

The tip of the stick may have a spatula shape, a flat surface, or a curved surface, and one or both ends of the stick may have different shapes. The pressing time is not particularly limited, but is about 0.1 to 10 seconds. Further, after the transfer, since the transfer layer on the tooth surface can be removed as needed, the color tone can be temporarily changed.

The pressure transferring chamber of the present invention may be formed in a shape corresponding to the above-described method of use, and may be formed in a sheet shape or the like in response to the number or area of the teeth to be treated. The width and length can be appropriately adjusted. However, In this case, it is preferable to have not only a simple rectangle but also a curved line along the cervical portion.

For example, in the case of attaching to six teeth of the upper right triple-upper right triple three, a width of 48 to 60 mm and a height of 9 to 11 mm, and a shape having a mountain-like curve along the tooth part on the side contacting the gum . When the tooth is attached to six teeth of the lower right jug 3 and lower jug 3 times, the shape is smaller than that of the upper jug and has a width of 36 to 46 mm and a height of 7 to 9 mm. . Further, in order to fit the arch of the teeth, it is preferable that the shape is such as a V-shape or a bow.

The pressure transferring chamber of the present invention preferably has a release liner for the purpose of protecting the pressure-sensitive adhesive layer, and it is preferable that the surface of the pressure-sensitive adhesive layer before application to the teeth is covered with a release liner. As the release liner, silicone-coated glycine paper, polyethylene terephthalate, polyethylene, polypropylene, or the like can be used. For example, 70GS (3) or the like manufactured by Prince Special Nippon Co., Ltd. can be suitably used.
