Description

Nail thermoformable prosthesis and device heater.

The present invention, applicable in the market and the industry of the aesthetics of the hands, refers to a nail prefabricated prosthesis with the acrylic material known as "porcelain to sculpt nails", which once manufactured is It can be thermoformed by heating it with a designed thermal device for this purpose, the device generates heat and when transferred by contact with the acrylic porcelain prosthesis, it softens, allowing to vary its shape adopting that of the natural nail where it It intends to install when pressed on it evenly. This prosthesis is designed to fulfill the function of improving the aesthetic appearance of the hands when installing an artificial nail prefabricated with porcelain and adaptable by manual thermoforming to the shape of the natural nail where it will be fixed with the same material with The one that is manufactured, make it easy to install durability and natural appearance

Background of the invention

Various products are currently known and procedures aimed at manufacturing and installing nails artificial, particularly those that refer to the sculpted nail construction, known in the guild as "nails of porcelain ", directly on the fingers on the nails natural, applying a mixture of a powder acrylic multimeter with a liquid acrylic monomer and give this mixture a nail shape before it polymerizes, once hardened it finishes forming as a nail with files and strawberries to give the thickness and final finish adequate, which makes this practice a work specialized and handmade where skill is required to sculpt in addition to an important time investment in your process.

They are also known as "gel nails acrylic "those that use an acrylic resin sensitive to ultraviolet rays which hardens when exposed to them, the procedure for the construction of a gel nail is similar to of the porcelain.

There are also previously manufactured nails of various plastics, which have to be attached to the nails natural with glues that are generally not efficient and they end up falling apart, besides the end result is not It looks as natural as porcelain.

However, the existence of a prefabricated artificial nail made of acrylic material (porcelain) that: is thermoformable at temperatures bearable by the man, can fulfill the function of nail prosthesis, can install directly on the natural nail and be adaptable by thermoforming to the shape of the nail where it will be fixed, and also Be stable, durable, good looking natural, easy application and does not require to be sculpted or of a specialized ability to be installed.

The obvious solution to this problem would be the previously build the prosthetic nails with the same material with which are made of sculpted porcelain nails, which are susceptible to being thermoformed at no high temperatures and so manual to adapt to the required form, in addition to being able to fix to natural nails with a small portion of the same material with which is made, which is already known to adhere excellently to the natural nail and is welded to the nail prosthesis.

Description of the invention

Prefabricated and thermoformed prosthetic nails that the invention proposes, are constituted by curved sheets nail-shaped acrylic material (porcelain), and are manufactured previously with appropriate molds for this purpose, also the invention includes a heating apparatus.

The molds are composed of two parts the which are joined by pressure through a press, one of the parts It is concave with the proper curved shape to a nail, the other part is convex and corresponding to the front part of the mold, when assemble, between the two parts of the mold will be a space adjusted to the thickness and shape that is intended as Outcome.

The convex part of the mold contains some blades that will cut the material and define the final contour of the product.

A heating device will supply heat to the convex part of the mold to accelerate the process of polymerization, hardening and drying of porcelain. The material to be used to manufacture the "prosthetic nails thermoformable porcelain "is composed of a polymer acrylic powder and a liquid acrylic monomer which at mix polymerize and result in a rigid material, highly adherent, susceptible to being thermoformed, known as "nail porcelain", so an item is required insulator between the mold and the mixture of the acrylic polymer powder and the liquid acrylic monomer, which, without establishing limitation some may be, two thin sheets of polyethylene, this material which is not adherent to porcelain.

One of these sheets is shaped previously equal to the useful surface of the concave mold, that is achieved through a thermoforming process of the film of polyethylene providing heat and subjecting it to the action of a rigid mold through pressure.

Once the thermoformed film of polyethylene, is placed on the useful surface of the concave part of the mold making it coincide and fitting it into it, the cavity concave covered by polyethylene film is filled with liquid acrylic monomer, then the acrylic polymer is applied in powder until the liquid is absorbed, if parts of the powder remain moisten, more monomer is supplied until the powder remains completely dissolved in the liquid.

Next, another flat film of polyethylene on the surface of this part of the mold already loaded with the acrylic mixture to be molded.

The next step is to match the two parts of the mold, which are provided with appropriate guides for your exact match, in this step you have to take in Consideration that the other part of the mold, the convex, is properly hot. Once this is done, both parties submit at the pressure of a press that will force the acrylic material to take the internal shape of the mold once it is assembled.

After the prosthesis nails come out of the mold, can be softened by providing heat with a device thermal to give a proper shape to the natural nail where it goes to install.

The thermal device has a electrical resistance calculated for a power that supplies the necessary heat, for which the device heat dissipation capacity, where it is resistance is installed according to the design that has been done.

This thermal device, in addition to the resistance, must have a metal part or any material that is a good conductor of heat and will be the one that will be in contact with the electrical resistance, in addition to having a indicator system that lets you know when it is on or off, you must also have a power supply or a means of connection to the mains, also covering heat insulating material or little conductor of this for easy manipulation, a hinge system and mechanical pressure (it can be a spring) to hold the "nail thermoformable prosthesis porcelain "which when coming into contact with the conductive material of heat, already hot, transfer the heat to the nail causing it softens, a state that will keep enough time to be able to place it on the natural nail and adapt to its shape.

Optionally these devices can Equip with temperature indicating sensors and / or timers

The procedure to install the nail prefabricated to the natural nail consists of applying a portion of acrylic polymer powder moistened with liquid acrylic monomer on the natural nail which has previously been prepared by scraping it with a nail file or with a chemical capable of make porosities in it and extract the fats or elements that prevent adherence, this does not set any limitation the way the natural nail can be prepared, any procedure capable of conditioning it for good adhesion of the porcelain on it is acceptable, once the nail is prepared natural and after having impregnated the acrylic polymer in powder moistened with liquid acrylic monomer is placed on top the porcelain nail prosthesis already thermoformed by providing some uniform pressure, as a consequence of this, the acrylic polymer in powder moistened with the liquid acrylic monomer will be fixed firmly to the natural nail and will be welded to the nail prosthesis porcelain, resulting in a uniform and compact body just as if he had been sculpted in the way he is currently make.
