Description

Tooth whitening patch {tooth whitening strip}

Industrial use field

The present invention relates to a patch for whitening teeth, and more particularly to a whitening patch that provides a sufficient amount of adhesion and contact time to whiten teeth.

Patches include tooth whitening agents and films.

More specifically, it is a one-time tooth whitening patch that is easy to use, inexpensive, and can be applied to several adjacent teeth at once.

Prior art

The most commonly used tool for dental health is a toothbrush. The toothbrush removes foreign matter or plaque by the mechanical action of the bristles. Toothpaste has been used to increase the effectiveness of the toothbrush mechanical action.

Toothpaste is mainly composed of abrasives and foaming agents, but with the development of technology, active ingredients such as fluorine, antibacterial and anti-inflammatory agents are used to enhance dental hygiene. Consumers are also interested in whitening teeth. Professional tooth whitening procedures by dentists have been offered to people and are still taking place. However, the treatment of this dental clinic is far from the interest of many consumers due to a lot of time, cost and inconvenience.

In addition, whitening toothpaste has been developed to provide teeth whitening in the range of everyday life, but its effect is so small that it is difficult to identify a significant effect in a short period of time. To solve these problems, tooth whitening products of various formulations and related technologies and patents have recently appeared.

Among them, professional whitening gel should be visited by a doctor 1 or 2 times for initial treatment. After that, the whitening agent should be applied to the mouth tray at home, and the period is 2-4 weeks. Therefore, there is a disadvantage that is inconvenient and expensive.

In order to overcome this drawback, Japanese Lions has disclosed a sheet-type oral patch in Japanese Patent No. 10017448. The tooth whitening agent used in this patent claims that ascorbic acid derivatives, urea peroxide, yeast acid and various salts are effective. These ingredients are acidic and can cause problems with your teeth by reducing the pH.

Pienzi Co., Ltd. in the United States of the United States Patents 5879691, 589407, 5891453 discloses an oral whitening strif applied to the teeth by applying a whitening agent to a thin film. The method of use has been improved very easily, but the whitening agent is difficult to penetrate into the curved part of the tooth and deep between the tooth by increasing the viscosity to improve the adhesiveness, attach the strip to the tooth and resist the pressing strength when pressed. There is a disadvantage that it is difficult to obtain the effect.

Colgate in the United States discloses a method in which the active ingredient is rotted in a compound (Dow Corning 3179 Dilatant Compound) in US Patent 530563 to remove it after use. However, since the active ingredient is difficult to be applied to the tooth surface in a short time, a long term is required to obtain a whitening effect.

-LG Ciasa used methacryloyl ethyl betaine / methacrylate copolymer (Yukaformer) as a film former in the support layer in Korea Patent Publication No. 2001-010020, but it is difficult to have a suitable strength and shape to use There is an inconvenience that is broken or difficult to apply

To solve the above inconvenience problems

The tooth whitening patch is attached to several adjacent teeth by the wearer. When attaching, the whitening agent can be maintained as it is by forming a support or column on the film to prevent the whitening agent from escaping from the film by various actions, and the whitening agent can be maintained as it is. It provides a tooth whitening patch that can be easily penetrated into difficult to penetrate.

Means to solve the problem

In order to achieve the above object of the present invention, the present invention is a patch for tooth whitening comprising a film and a tooth whitening layer.

film

The film is waterproof and substantially prevents the saliva of the mouth from coming into contact with the whitening layer to dissolve or eroding the whitening layer by the user's lips, tongue and other tissues.

The film is made of a material such as polymer, natural or synthetic woven fabric, nonwoven or foil, paper, rubber and combinations thereof.

The film may be a single layer of material 12 or one or more layers 13.

The material may consist of a single polymer or a mixture of polymers.

Suitable polymers can include polyethylene, ethylvinylacetate, ethylvinylalcohol, polyester, teflon.

The film may be planar and may be shaped with various types of supports capable of supporting the whitening layer.

This support prevents the whitening layer from being pushed out of the film by the user when the patch is attached to the tooth and by the movement of the lips or tongue after attachment. These supports may be of various shapes, such as pillars 15, islands 17, meshes 19, cylinders 15, triangular horns 18, etc., which are attached to the support on the film. It may be formed by forming a film or by compression when forming a film.

If the strength of the film is too weak, it is difficult to handle it because it is folded or bent when attached to the teeth.

Whitening layer

The whitening layer is a composition capable of whitening teeth. Teeth whitening includes, but is not limited to, stain removal, stain bleaching, plaque removal, tartar removal tooth surface restoration, and the like.

The whitening layer may be mixed or rotted, such as a millennium and a net-like material such as nonwoven or nonwoven or polymer synthetic resin.

The whitening layer is a liquid, gel, or paste that has a moderate viscosity so that it can easily penetrate into the curved area of the tooth and the gap between the tooth and the tooth, or it can be mixed with the saliva in the oral cavity to become the liquid, gel, or paste state. Or in the solid phase. The whitening layer's range is less than 10000 cps, so it is difficult to maintain its shape. At more than 2 million cps, it is too viscous to penetrate the narrow gap between the teeth.

Hereinafter, the present invention will be described in detail.

In order to use as a patch for tooth whitening agent, a film of moderate viscosity containing a whitening ingredient, a whitening layer 11 in a paste state, is used on the film 12 and the film is too thick when the whitening patch agent (FIG. 1) is used. To reduce discomfort when attaching to teeth by thinning or folding it, use the appropriate bending strength and also prevent the large amount of whitening layer from leaking to the outside when the user presses the whitening patch with the intention of making it stick to the teeth. In order to install a support between the film and the whitening layer so that a certain amount remains. In addition, instead of the support 14, a natural or synthetic woven or nonwoven fabric or a net-like polymer or plastic is installed between the film and the whitening layer (FIG. 4) to prevent the whitening layer from falling out of the film. In addition, because of this support, the viscosity of the whitening layer can be lowered to a certain level, so that the whitening layer can be easily penetrated to the teeth, the teeth, or the curved part.

The tooth whitening deodorant of the present invention is a whitening layer having a suitable viscosity is applied on a film having a support of a suitable shape. Easy to use on teeth, excellent whitening effect and even whitening effect on every surface of tooth.
