DETAILED DESCRIPTION
This invention, referred to herein as a wax dispenser, is a device for melting and dispensing wax for use in the hair removal process, otherwise known as depilatory waxing. This wax dispenser is designed to provide a portion of hot wax, of selectable quantity, for each individual client, thereby minimizing the risk of client-to-client cross contamination.
Prior to this invention a typical depilatory waxing procedure involved heating a significant quantity of wax to a temperature of between 120° F. to 140° F. in a pot similar to a crock-pot. The amount of hot wax that is thus prepared is generally sufficient for a number of clients and in kept in a communal pot, where it is kept sufficiently hot to remain melted. A wooden stick (similar to a tongue depressor or a Popsicle stick) is dipped into the hot wax and applied to the client's skin. Although illegal in many jurisdictions and certainly not best practice, it is a common practice to use and resuse the same stick for second, third and continuous applications, until the desired areas of the client's body are free of hair. This process is referred to in the trade as “double dipping.” While the esthetician may not reuse a stick with multiple clients, the process of “double dipping” serves to transfer from the client hair and in some instances fluids from the clients back to the communal pot. Since hot wax is an excellent breading and/or maintenance ground for germs and viruses, the “double dipping” technique common in the trade have been shown to increase the likelihood of cross-contamination of serious infections diseases and maladies. A variety of approaches have been proposed to deal with this cross contamination problem. The most common of which is use of roll-on waxing systems. However, this roll-on approach has been unsuccessful at solving this problem because (1) it allows wax that has touched a client's body to re-enter the roller head thereby contaminating other wax; (2) it is inconvenient because it changes the esthetician's routine and dictates the type or brand of wax that can be used; and (3) it is expensive compared to the more traditional stick application approach. Attempts by esthetician's to control costs have led some estheticians to reuse roller heads for multiple clients, thereby exasperating the cross contamination problem.
This hot wax dispenser addresses this problem directly. Cross contamination is eliminated by eliminating access to the communal pot of wax. Each client receives wax from a disposable cup containing only wax for their use. The esthetician may double dip into the client's disposable cup because, so long as a new disposable liner is used for each client, there is no risk of contaminating the wax used for subsequent clients. This wax dispenser does not require the esthetician to change their routine in any significant manner. It does, however, avoid cross contamination further by eliminating access to the wax to be used for subsequent clients. This wax dispenser is designed and adapted to accommodate most if not all types and brands of depilatory wax, whether in bead, brick or can form. Again, one of the most important features of this invention is that it provides an individual client sized disposable cup of wax, while removing access to the heated reservoir of hot wax used for subsequent clients, and thereby minimizing the cross-contamination problem caused by “double dipping” in depilatory waxing.
FIG. 1 shows a perspective view of the present embodiment of the wax dispenser 100 of this invention. A body portion 102 is provided, within which is the wax retainer, the heater assembly and the dispensing assembly. A handle 101 is provided for activating the dispensing assembly, thereby releasing melted wax to the cup 103 with its insert 106. A cup handle 104 is provided to facilitate extraction of the cup 103. Although the cup 103 is generally not removed during operation and wax can be dispensed with the cup 103 in either the in or the out position. In either situation, the insert 106 preferably stays in the heated area of the cup 103. A window 107 is provided in the cup 103 to permit a user to see the wax as it flows into the cup 103 or its insert 106 and to insure that the cup 103 does not hold wax without an insert 106 in place. A lid 105 is provided to allow access to the wax retainer. It is worth noting, however, that the lid does not provide access to melted hot wax because the wax in the retainer as it melts flows through a grate to a reservoir or bulk-heating bowl within the body portion 102. The grate insures that a user cannot reach hot melted wax in the bulk-heating bowl through the lid. These internal components are shown in more detail proximate to their assembly in FIGS. 4 and 5.
FIG. 2 shows a top view of the present embodiment of the wax dispenser 100 of this invention. This view shows the wax dispenser 100 with the support legs 201a,b attached to the body portion 102, as an extension of the handle 101. FIG. 3 shows a front view of the present embodiment of the wax dispenser 100 of this invention. This view provides additional detail of the heat selection knob 301 and its various setting locations 302a,b,c,d,e, which in the present embodiment are used as a visual guide to a smooth turn heat selection knob, on the front of the body portion 102. In the present embodiment, by adjusting the knob in a clock-wise direction the temperature of the wax in the bulk heating bowl is increased.
FIG. 4 shows a side/section view of the present embodiment of the wax dispenser 100 of this invention. This view is a section view taken from the side to show the various components in a fully assembled configuration. Under the lid 105 is heat conducting plate 401. The can or other receptacle holding the wax is positioned upside-down on the grate 405. The heat conducting plate 401 is a metal plate which conducts heat from the heater 410a in the lid 105 to the wax containing can. As the wax melts it flows through the grate 405. While in the present embodiment the wax is provided in a can, in alternative embodiments, the wax may be simply placed on the grate directly. The wax may be in the form of a brick, beads or the like. In the present embodiment, the heat conducting plate 401 is fixed to the lid 105 by a number of screws 402a,b,c so that with the lid 105 flipped open on its hinge 403 the heat conducting plate 401 can receive a can or other bulk wax holding receptacle. When the lid 105 is closed the top of the can is then reversed so that the melted wax will flow freely out of the can down into the interior of the body portion 102. Attached to the heat conducting plate 401 can be a number of spring clips 404a–e for frictionally holding the can in place. In one present alternative embodiment these spring clips 404a–e are not provided and the was or wax container simply rests directly on the grate 405. Immediately below the clips 404a–c and the can when placed below the heat conducting plate 401 is the grate 405. The grate 405 is provided with a number of openings, as shown in FIG. 5, sufficient to allow the melted wax to flow through the grate 405 to the bulk heating bowl 406 below the grate 405. A valve 408 is attached to the bottom of the bulk-heating bowl 406 is connected 407 to the handle 101. When the handle 101 is pressed, the interior of the valve is turned permitted the melted wax to flow through a valve 408 to the insert 106 in the cup 103. By pulling on the cup handle 104, the cup 103 assembly 409 is brought forward permitting the user to remove the insert 106, now containing hot wax for use on a single client. The cup 103 assembly 409 can be in either the in or the out position when dispensing wax. The insert 106 stays in the heated area of the cup 103 while the client is being waxed. The insert 106 is disposed of once the client waxing is completed. Typically, although not necessarily, the client waxing is performed with the cup 103 in an out position and the insert 106 still in the cup 103. Several heating elements 410a,b,c are provided. A first heating element 410a is located above the heat conducting plate 401. Since, typically the heat conducting plate 401 and the clips 402a–e, if used, are made of good heat conducting metal, the heat from this first heating element 410a is conducted to the can containing the bulk wax for melting this wax. A second heating element 410b is located under the under the bulk heating bowl 406 for keeping the melted wax in a liquid state. A third heating element 410c is located under the cup plate 411, which supports the cup 103, for keeping the dispensed wax in the disposable insert melted. Each of the heating elements 110a,b,c controlled by the selection knob 301, limited by a thermostatic switch 412 provided to avoid overheating for safety purposes.
