Abstract

Roll-on depilatory and self-heating wax through a chemical reaction. Roll-on that where it is not necessary to heat the wax by external means (microwave, water bath, electric heater, etc.) but through an exothermic chemical reaction that occurs in an annexed compartment where the wax is. The roll-on consists of a body where the wax is located, a boiler or tank where the chemical reaction is carried out, a roller and a head. Joining two or more chemicals in the boiler produces an exothermic chemical reaction, which increases the temperature inside the boiler and will transmit heat through the walls to the wax. The amount of heat needed will depend on the type of wax and its melting point and is obtained by modifying the amount of reagents.

Description

Depilatory wax roll-on and self-heating through a chemical reaction.

Technical sector

The present invention, as expressed in the enunciated of this descriptive memory, falls within the sector of hair removal products, more specifically in those that use depilatory wax and Roll-On type to dose this one.

State of the art

The chemical reactions have been used in many occasions to produce heat (exothermic reactions) or cold (endothermic reactions).

These reactions have many utilities such as in heating kits (anhydrous CaCl2 + H2O) or for cooling (NH 4 NO 3 + H 2 O), to heat containers (cans) with coffee, etc.

Depilatory wax is a commonly used method. known for hair extraction. It heats up reach its melting point and subsequently applied on the skin. After cooling, by a pull (to the wax or to some bands adhered to the wax), the hair is removed.

Wax application methods that exist They are as follows:

-

Remove the wax from the container where it is has heated with a spatula or similar utensil. (Like the one who extract butter).

-

Roll-On: system that by middle of a roller spreads a thin film on the skin wax. This is stored in an attached warehouse.

In the case of Roll-On, the form of heating the wax has always been by external means to it, for example:

one.

Electric system. A roll-on is inserted into a device with a electrical resistance that heats a tank in which Find the wax.

2.

He Wax roll-on is heated in the microwave, when water bath or other external method.

3.

Two inner one tanks with very low melting point wax contained in another in which hot water is poured.

Explanation Technical problem raised

It would be desirable to obtain a system that we allow to heat the wax when we do not have external means to do it (at the campsite, beach, ...) and the wax reaches the suitable temperature to be able to dose with the Roll-On on the skin.

Solution

The technical problem is solved by activating a exothermic chemical reaction that develops in a reservoir next to the wax and transmitting the necessary heat to it to be applied

What we have is a Roll-On with independent compartments One where the wax will be stored until the heat is transmitted and can be applied to the skin to through the roller. In another compartment the exothermic chemical reaction and through its walls will transmit the heat to the wax compartment.

This compartment where the chemical reaction can be subdivided into compartments independent in which each of the products is stored. Communicating these compartments and mixing will react. Other option will be to have in this compartment one (or none) of the products and add the others to cause the reaction.

Technical advantage provided by the invention

The technical advantage provided by this invention is mainly that you don't need external means to heat the wax.

The Roll-On is purchased with chemicals, wax, roller, etc., and the user must only activate the reaction and wait for the wax to take a temperature to start applying it. This fact gives the user great flexibility when using it.
(in campsites, beach, boats, etc.). Places where hot water, microwave, kitchen are not available. ...

Compared to the three systems or methods of heating mentioned above

Facing the electrical system: you don't need a nearby electricity source nor is it necessary to own a device Heater.

Facing to heat it in the microwave or bathroom Maria, we don't need a water heater, or a stove or other source of energy or a microwave oven.

Facing the hot water method, we have Also numerous advantages. Wax does not have to have a point melting so low, so it pulls more hair to be more effective. In addition we do not need a means of obtaining water hot (hot running water or heater, microwave, ...). The small amount of water that might be needed (if it were the case) to activate the chemical reaction, it can come in the container included

Description of the drawings

Figures 1 and 2.- Front view and profile of a Conventional roll-on

It has three distinct parts:

\ sqbullet

The Body, which is nothing else than the deposit where the wax is stored.

\ sqbullet

The head, which is the element which serves to hold the roller. It is usually attached to the body by a thread or pressure system.

\ sqbullet

The roller that serves to be able to apply the wax in the form of a thin film. It revolves around its axis that is skewered in the head.

Figures 3 and 4.- Front and profile views self-heating roll-on

It is identical to a roll-on conventional except that included in the body is a compartment (which in turn can be subdivided) where it It will produce the chemical reaction. We will call it a boiler.

In the boiler will be all or several of the chemical products and after adding those that remain or after making come into contact (for example by breaking a barrier of separation) the chemical reaction will occur.

Figures 5 and 6.- Example of realization self-heating roll-on

This is an explanation of a way of realization.

Figure 5 shows the system without Activate.

The boiler is divided into two compartments for a double plastic sheet. In each of the compartments We have the products that will react to heat.

Figure 6 shows the form of activate it

Pulling the ring we communicate the compartments Waving we will make it homogenize and when activated the heat reaction will be transmitted through the walls of the wax boiler.

Description of embodiments

Initially we have to decide a reaction Chemistry that is very exothermic, and cheap products, at the same time it is not necessary to add a lot of energy for the reaction start

One that seems quite appropriate may be the which is produced by joining calcium oxide with water to give hydroxide Calcium more heat.

2CaO + H 2 O ? 2 CaOH + Hot

This reaction practically starts without contribution of energy, just shake the products a little so that mix well.

Mode one

The calcium oxide would be stored in the boiler, and would be separated from the water by a double sheet of plastic attached to the walls of the boiler, so that the water cannot transfer the plastic sheet (See drawing 3).

When the ring is pulled, the plastic sheet is separated from the boiler walls, which causes the water to mix with the calcium oxide. However, being double, the products do not go abroad.
rior.

Once they mix, just shake and wait a few minutes. The temperature can reach 90º, so that heat will be transmitted through the walls of the boiler On the wax.

Of course the amount of CaO and Water will depend of the volume of wax contained in the Roll-On.

Once the wax has warmed, it proceeds application.

Mode 2

Another option is to have the CaO in the boiler and introduce (Via a syringe, ampoule, etc.) the amount of water necessary and shake.

The tank where the reaction will occur chemical and water is either added later or found in another deposit included in this one. To activate the reaction it would be enough to communicate the two deposits so that the water pour over the calcium oxide and stirring.

Industrial application

The Industrial application is evident in Roll-
On can be manufactured and sold to compete with other wax products that are used when there are no external means to heat the wax (Cold wax bands, depilatory foams, ...)

Roll-On manufacturing is something more expensive than that of a conventional Roll-On, but not much else.

Calcium oxide and water are products abundant and cheap.
