Description

Slot structure for mouth

This creation is about a patch structure for oral use, especially a dental patch structure containing whitening ingredients.

People suffer from abnormal life or immune disorders, causing oral ulcers in the mucous membrane or epithelium around the mouth and lips. It is usually applied with powder or ointment, and it is not easy to heal quickly. On the other hand, in the era when people are getting closer and closer, the treatment of tooth whitening is getting more and more attention. At present, many dental clinics have treatments that increase whitening teeth, such as cold whitening, laser whitening, etc. Even TV shopping channels have a variety of teeth whitening products.

U.S. Patent No. 6,419,906 discloses a patch suitable for tooth whitening comprising a thermoplastic polyoxyethylene and a solid percarbonate as a tooth whitening agent which may be present with a peroxide. It is highly compatible, but it has a low adsorption force with teeth. Therefore, the strip made of this material has poor wearability.

At present, the patch for whitening teeth is made into a thin layer of tooth whitening agent and adhered to a polyethylene patch. The patch of whitening teeth is wet, but its adsorption strength is not large. In addition, the colloid in the patch is easy to fall off and smash, which causes problems for consumers and manufacturers.

In addition, the current dental patch on the market has insufficient fit to the teeth. Even if the flatness or the large gap is not tight, it will not fit tightly, resulting in poor whitening effect. In addition, many products also have gels that are more resistant to water adhesion due to water absorption, which causes the user's dental patches to fall off easily, often failing to achieve the desired whitening effect.

In order to solve the above problems, the creator improved the patch structure of the traditional oral use to obtain the present creation. The patch structure of the mouthpiece of the present invention has a multi-directional stretchable isolation layer, which allows the user to feel soft and comfortable and has a good applicability, and the adhesive does not decrease after the colloidal water meets the desired effect.

The "mouth" in this creation includes, but is not limited to, moist areas of the mouth water, such as the lips, the inside of the mouth such as teeth and oral mucosa.

The present invention provides an oral patch structure comprising: a barrier layer having a multi-directional stretchability; and a glue layer comprising a backing material and a colloid coated thereon, the backing material being attached to the multi-directional Stretching ability on the barrier layer. The multi-directional stretchable isolation layer is used to isolate the adhesive layer from contact with the external environment. In a preferred embodiment, the barrier layer having a multi-directional stretchability is a polyurethane film layer.

The colloid used in the patch structure of the present invention can increase the viscosity when it is in contact with water, and its composition includes, but not limited to, ethanol (accounting for 40-60% of the total weight of the colloid), and polyethylene glycol (PEG) (Polyethylene Glycol, PEG). 5% by weight of the colloid, polyvinylpyrrolidone (PVP) (15-30% by weight of the colloid), Hydroxyethyl Cellulose (10-15% by weight of the colloid) )Wait.

The back material of the patch structure of the present invention can carry a colloid, and the back material and the colloid form a glue layer to fit on the separation layer with multi-directional stretching ability, and the back material is composed Including but not limited to fiber paper (such as long fiber paper), nylon mesh, PU, PET, PP, non-woven fabric, and the like.

The oral patch structure of the present invention contains a gel layer and at least one active ingredient (such as an anti-inflammatory drug or a whitening substance), which may have different components and ratios depending on the product. Therefore, the oral patch structure of the present invention can be prepared as an oral patch for oral ulcers in the oral cavity and the mucosa or epithelium around the lips, which can contain an anti-inflammatory drug. In a preferred embodiment, the oral patch structure of the present invention can be prepared as a tooth whitening patch, the active ingredient being a tooth whitening substance; in a more preferred embodiment, the tooth whitening substance is peroxidized. Peroxide, which includes, but is not limited to, hydrogen peroxide (Hydrogen Peroxide), which comprises from 3% to 15%, preferably 6%, based on the total weight of the colloid and active ingredient.

The oral patch structure of the present invention may further comprise a release layer, such that the adhesive layer may be attached to the release layer to protect the adhesive layer. In a preferred embodiment, the release layer is made of a non-transparent or transparent material. In a more preferred embodiment, the release layer comprises polyethylene terephthalate, polyproylene, polyethylene, release paper or crepe film.

The oral patch structure of the present invention is for covering the tooth surface of the tooth and the back of the tooth; in a preferred embodiment, the patch structure of the mouth is curved, circular or planar.

Figure 1 is a schematic view showing the structure of the oral patch of the present invention.

1 is a schematic view of a die structure 100 of the present invention, comprising: a spacer 101 having a multi-directional stretchability; and a glue layer 102 comprising a backing material 1021 and a colloid 1022 coated thereon. The backing material 1021 is attached to the isolation layer 101 having a multi-directional tensile capability, and further comprises at least one The release layer 103 is used to protect the combination of the adhesive layer 102 and the isolation layer 101.

In detail, the mouth piece structure 100 of the present invention first prepares a main body layer composed of 53% ethanol, 14% polyethylene glycol, 21% polyvinylpyrrolidone and 12% hydroxyethyl cellulose. Then, the active ingredient hydrogen peroxide is added to the main body layer in an amount of 3% by weight based on the total weight of the main body layer plus hydrogen peroxide. The gel is applied to the long polymeric fibers and baked in an oven to completely evaporate the alcohol components. After the isolation layer is applied to the non-coating surface of the long polymer fiber, a combined layer of the adhesive layer 102 is adhered to the separator 101, and the combined layer is subjected to punching into a semi-finished product. Finally, two release films (release layers 103, 103') are respectively attached to the colloidal surface and the isolation layer of the semi-finished product, or a release film 103 is attached to the adhesive surface to prepare the adhesive for the creation. Slice structure.

In the patch structure of the present invention, the multi-directional stretchable barrier layer 101 and the adhesive layer 102 can be bonded by an adhesive, a low-sensitivity adhesive or a hydrophilic or hydrophobic adhesive.

The oral patch structure 100 of the present invention is used to cover the tooth surface and the back of the tooth; in a preferred embodiment, the dental patch structure 100 is curved, but not limited thereto. The shape of the covered teeth can be used.

When the present invention is used, the multi-directional stretchable barrier layer 101 and the glue-containing layer 102 coated thereon are peeled off from the release layer 103 and applied to the teeth due to the multi-directional stretching ability. The barrier layer 101 has a multi-directional stretching ability, can be applied to the uneven tooth surface and deep into the teeth, and can cover the tooth surface and the back of the tooth, so that the tooth patch of the creation can achieve better whitening or the skin. The effect to be achieved.

Although the present invention is disclosed above in the foregoing embodiments, it is not intended to limit the present invention, and anyone skilled in the art can make some changes without departing from the spirit and scope of the present invention. The scope of patent protection of this creation is subject to the definition of the patent application scope attached to this specification.
