Wax-warmer for depilation with ejection device

Description

[0001] The present invention concerns a wax-warmer for depilation of the type comprising a casing open at one end, designed to contain a depilation wax package and provided with resistive means for warming and smelting the wax contained in the package.

[0002] The depilation wax at room temperature is solid or, however, pasty thus making it impossibile to apply onto the skin. Therefore, it is necessary to warm the wax in order to smelt it, so as to make it possible to apply onto the skin where, cooling down, it solidifies forming a single layer together with the hair; by pulling away this layer, the hair included in the wax layer is eliminated.

[0003] Wax-warmer devices containing a depilation wax package or cartridge, which have a wax distributor roller at the upper end, are well-known. By electrically supplying the resistive means of the wax-warmer, the wax contained in the package is warmed at a temperature sufficient to smelt it so that, holding the wax-warmer containing the wax package in hand, it is possible to spread the smelted wax onto the skin without the risk of burns. Obvoiusly, as soon as the wax is sufficiently smelted, the electric supply to the resitive means is interupted. When the application of the wax on the skin is terminated, the wax package, which remains inside the wax-warmer, cools and the wax contained therein solidifies again.

[0004] Once the wax package is exhausted, they have to substitute it with a new one, whereby it is necessary to remove the old one.

[0005] However, the continuous smelting operations, applications of the wax onto the skin and its solidifying, make the wax, which comes out from the distributor roller, able to dirty the upper part of the wax package creating different problems. In fact, when trying to extract the empty package, the user easily gets dirty and, furthermore, due to the unctuosity of the wax, the package becomes slippery hampering the extraction of the empty package. Another drawback is due to the fact that the user does not notice when the wax package is getting exhausted unless, every now and then, he extracts the package to verify the wax level contained therein with all the problems, previously stated. Document WO-9826687 discloses the preamble of claim 1.

[0006] The aim of the invention is that of eliminating all the drawbacks cited with reference to the described prior art.

[0007] The aim is reached with a wax-warmer of the above-mentioned type, that is a wax-warmer for depilation of the type comprising a casing open at one end, designed to contain a depilation wax package and provided with resistive means for warming and smelting the wax contained in the package, characterized in that it comprises ejection means of said package from said casing.

[0008] In such a way, in order to eject the package, it is sufficient to operate onto the ejection means which allow an easy extraction of the package without, furthermore, running the risk of getting the hands dirty.

[0009] The ejection means are of manual-operated type, consequently they are simple, cheap and reliable. Moreover, the wax-warmer comprises elastic means which return the ejection means to their original position after they have ejected the wax package, so as to allow the new package to enter.

[0010] The wax-warmer is provided with a little transparent window which is resistant to a minimum of 60°C, in order to check the wax level contained inside the package, and therefore to substitute the package when the wax therein is exhausted.

[0011] The resitive means are preferably made of an electric resistance with a positive temperature coefficient, namely of the PTC type in order to limit the maximum value of the electric current intensity as the temperature rises.

[0012] These and other advatages of the invention will be more evident from the following detailed description of an embodiment made for exemplifying and not limiting the scope, with reference to the subsequent figures wherein:

• figure 1 ia a side view of a wax-warmer according to the present invention;
• figure 2 is an elevation cross-section of the wax-warmer of figure 1 taken along the section line II-II in which the ejection device is represented in an inoperative postion;
• figure 3 is an enlarged view of the ejection device represented in figure 2;
• figure 4 is an elevation cross-section similar to those of figure 2 wherein the ejection device is represented in an operative position.

[0013] In figures 1, 2 and 4 a wax-warmer for depilation is completely represented with reference 10. The wax-warmer 10 comprises a casing 12 consisting of a base 12a, a side wall 12b defining an upper opening 12c and a double bottom 12d. The side wall 12b and the double bottom 12d define a housing seat 14 designed to house wax packages 16.

[0014] The wax package 16 consists of a cartridge 18 containing depilation wax having an upper end in which a roller distributor 20 is mounted. In the casing 12 an electric resistance 22 of the PTC type (positive temperature coefficient) is positioned so that as the temperature rises, the value of the electric resistance 22 increases, thus limiting the maximum value of the electric current's intensity, avoiding in such a way problems due to overheating.

[0015] The wax-warmer 10 is provided with a manual-operated ejection device for the wax package 16, indicated in its entirety with reference 30. The ejection device 30, best illustrated in figure 3, comprises an ejector 32 formed with a plate 36, the opposite surfaces of which respectively have a semisphere-like knob 38 and a pin 40.

[0016] Inside the casing 12, between the base 12a and the double bottom 12d, a parallelepipedic chamber 42 is formed, longitudinally delimitated by two opposite walls: a lower wall 42a and an upper wall 42b both having dimensions substantially equal to those of the plate 36. Inside the chamber 42 the plate 36 longitudinally slides freely. The lower wall 42a has a hole 44 from which the knob 38 is free to come out, whereas the upper wall 42b has a hole 46 in which the pin 40 slides. The double bottom 12d also has a hole 48 from which the end of the pin 40 is free to come out.

[0017] Finally, the lower wall 42a is recessed in respect to the base 12a of the casing 12, so that when the plate 36 is positioned against the lower wall 42a of the chamber 42 and the knob 38 completely comes out from the chamber 42, the latter does not project outside with respect to the base 12a of the casing 12. Inside the chamber 42, between the plate 36 and the upper wall 42b of the chamber 42 an helicoidal spring 50 is interposed.

[0018] The functioning of the manual-operated extraction device 30 is as follwing. By completely inserting a wax package 16 inside the casing 12 by means of the upper opening 12c, the package 16 is contained in the housing seat 14 and abuts against the double bottom 12d. The pin 40 is almost completely housed in the chamber 42 and it does not project form the hole 48 of the double bottom 12d, the plate 36 is positioned against the lower wall 42a, and knob 38 completely comes out from the chamber 42. The ejection device 30 is in the rest or inoperative position, as illustrated in figures 2 and 3.

[0019] When the wax package 16 is exhausted and one has to proceed with its substitution, it is sufficient to press the knob 38 so as to move the plate 36 towards the upper wall 42b thus compressing the spring 50. The pin 40 slides inside the hole 46 of the upper wall 42b and comes out from the double bottom 12d through the hole 48, thus pressing on the bottom of the wax package 16. The ejection device 30 is in the operative position for ejecting the package 16, as represented in figure 4. After holding the wax package 16 in hand and extracting it completely from the casing 12, the knob 38 is released and the ejection device 30 returns to the original position again, illustrated in figures 2 and 3.

[0020] In the side wall 12b of the casing 12, near the double bottom 12d a substantially rectangular small window 60, which is transparent and resistant to a minimum of 60°C, is provided. Thus, it is possible to verify the wax level remaining inside the package 16 and, then, to notice when the package is exhausted in order to proceed with its substitution by a new package, obviously using the ejection device 30, as described above.

[0021] For example, it is possible to use a spring which reacts when strained, that is, when one uses the ejector 30 in order to eject the wax package 16, the spring is strained instead of being compressed.

[0022] For a better sliding, pin 40 may be provided with two guiding tongues which slide inside corresponding slots designed in the side walls of the chamber 42.
