[0099] In some embodiments, a depilatory resin is characterized by its ability to solidifies upon cooling. Such a resin is will be referred to herein as hard wax. The primary compounds in hard wax may include natural or synthetic resins, oils, and additives. These components contribute to the wax's flexibility, adhesiveness, and melting properties.

[0100] Natural resins such as rosin or colophony may be used in some embodiments. For example, these may have a melting point range from approximately 60 C. to 80 C. Synthetic alternatives, like polycyclopentadiene, may also be utilized. The synthetics may provide a broader melting point range of 50 C. to 90 C. For example, in total all of these components may make up 25 to 65% by weight of the hard wax.

[0101] Oils, such as mineral oil or vegetable oils like coconut or olive oil, may be incorporated. For example, these oils may enhance the pliability and skin conditioning properties of the wax. The oil content can vary widely, ranging from 5% to 30% by weight, depending on the desired consistency and application method.

[0102] Additives such as titanium dioxide or zinc oxide may be included. For example, these additives may improve the opacity and/or reduce skin irritation. These additives might constitute 1% to 10% of the formulation, contributing to the wax's overall texture and performance.

[0103] In some formulations, plasticizers like lanolin or beeswax may be added. For example, these ingredients may increase flexibility and/or reduce brittleness. The concentration of plasticizers can range from 2% to 15%, depending on the specific requirements of the hard wax.

[0104] The hardness of hard wax can be measured using a durometer, with values typically ranging from 30 to 70 Shore A. This property influences the ease of application and removal, as well as the wax's ability to adhere to hair rather than skin.

[0105] Adhesiveness is a property of hard wax with formulations exhibiting sufficient tack to grip hair effectively. The adhesiveness may be adjusted by varying the resin-to-oil ratio, allowing for a balance between hair removal efficiency and user comfort.

[0106] Density is another important characteristic, often ranging from 0.9 to 1.2 g/cm.sup.3. This parameter affects the wax's spread ability and the amount required for effective hair removal.

[0107] In some embodiments, colorants or fragrances may be added to enhance the aesthetic appeal of the wax. These components are typically used in small quantities, less than 1% of the total formulation.

[0108] The application temperature of hard wax is generally between 45 C. and 55 C., allowing it to be applied comfortably to the skin while maintaining its functional properties.

[0109] Hard wax formulations may also include stabilizers to prolong shelf life and maintain consistency over time. These stabilizers might be present in concentrations ranging from 0.5% to 5%.

[0110] In certain cases, hard wax may be formulated to include exfoliating agents, such as fine pumice or ground apricot seeds. This substance may provide additional skin benefits during the hair removal process.

[0111] In some embodiments, a depilatory resin is characterized by application in a thin layer and removed using cloth or paper strips. This formulation will be referred to as soft wax. Soft wax may include a combination of resins, oils, and other additives to achieve the desired properties.

[0112] The resin component of soft wax may include rosin or a synthetic alternative, with a melting point range of 50 C. to 70 C. This allows the wax to remain pliable at lower temperatures compared to hard wax. The resin component may make up 15 to 60% of the depilatory resin.

[0113] Oils, such as paraffin or soybean oil, may be included. For example, the oils may be used to adjust the viscosity and spread ability of the wax. The oil content in soft wax formulations can range from 10% to 40% by weight.

[0114] Additives like mica or silica may be incorporated into the depilatory resin. For example, the additives may enhance the texture and reduce stickiness. These additives might constitute 1% to 8% of the formulation.

[0115] The hardness of soft wax is generally lower than that of hard wax, with durometer values typically ranging from 10 to 40 Shore A. This softer consistency facilitates easier application and removal with strips.

[0116] Soft wax, which must effectively adhere to both hair and the removal strips. The resin-to-oil ratio can be adjusted to optimize this balance, ensuring efficient hair removal.

[0117] The density of soft wax is often in the range of 0.8 to 1.1 g/cm.sup.3, influencing the wax's application properties and the amount needed for effective coverage.

[0118] In some embodiments, a sugar paste depilatory resin will be used. For example, the sugar paste may be composed primarily of sugar, water, and citric acid or lemon juice. This formulation offers a natural option for hair removal with distinct properties.

[0119] 2. The sugar content in sugar paste can range from 60% to 80% by weight, providing the necessary consistency and adhesiveness for effective hair removal.

[0120] 3. The addition of citric acid or lemon juice, typically in the range of 1% to 5%, facilitates the inversion of sugar, contributing to the paste's pliability and ease of application.

[0121] In some embodiments, various depilatory resins described herein offer a range of compositions and properties tailored to different hair removal needs. Each formulation may be adjusted in terms of resin type, oil content, additives, and other components to achieve a desired balance of performance characteristics.

[0122] In some embodiments, a wax capsule designed for use in a wax applicator may exhibit various shapes and forms to accommodate different functionalities. Optionally, the capsule may have an elongated shape (e.g., a length to width ratio of between 1.5:1 to 3:1 and/or between 3:1 to 5:1 and/or between 5:1 to 10:1. The capsule may be cylindrical with a circular cross-section, or it may be tapered to inhibit sticking and residue within the wax chamber. For instance, a tapered design may facilitate the movement of the capsule within the chamber by reducing the spreading of wax against the chamber walls. Alternatively, the capsule may have a non-circular cross-section, such as a D-shape, which can aid in self-orientation when inserted into the chamber. The dorsal side of the capsule might be flat or convex, while the ventral side could be faceted or irregularly shaped to fit the chamber's inner wall.

[0123] The wax chamber itself is configured to accommodate these various capsule shapes and may include an opening for insertion and another for the exit of melted wax. A cover is optionally provided to seal the chamber, preventing wax spillage and leakage. This cover may slide or hinge between open and closed positions and could include a locking mechanism to inhibit opening during use. The chamber's design may also encourage proper alignment of asymmetric capsules, ensuring efficient wax deployment.

[0124] In some embodiments, the wax capsule may be wrapped with a material that could be removed before use or remain intact during deployment. The wrapping material might be resilient, protecting the wax prior to use, and could be meltable or soluble in the wax, dissolving upon heating without affecting the wax's function. Alternatively, the wrapper may be crushed during use, allowing for more complete ejection of the wax. In some designs, the wrapper may be in the form of a cartridge that remains in the chamber after the wax is deployed, facilitating easy removal post-use.

[0125] The cartridge design may vary, with some embodiments featuring a hollow structure that surrounds the wax capsule. The cartridge may be preloaded with the wax capsule, allowing the pushing element of the applicator to push the wax through the cartridge's hollow and out of the chamber. The cartridge might have a shape that matches or differs from the wax capsule, such as a D-shaped outer cross-section with a circular cylindrical hollow.

[0126] The wax capsule's wrapping material may be non-meltable, remaining in the chamber post-use, or it may be recyclable. Materials such as foil, paper, cardboard, or flexible polymers might be used, depending on the desired properties. Alternatively, the wrapping material could be meltable or soluble, integrating into the wax upon heating. This could enhance the wax's application and improve the user's skin condition. The wrapping material may include additives like polymers or oils to further enhance the wax's functionality.

[0127] In some embodiments, the wax capsule, wrapper, and cartridge are designed to provide flexibility and efficiency in wax application. Various shapes and materials may be used in these components. For example, this may allow for a customizable and user-friendly experience, accommodating different types of wax and application preferences.

DETAILED EXPEMPLARY EMBODIMENTS

[0128] Referring now to FIGS. 1A-B schematically illustrating, according to an exemplary embodiment, perspective partial views of a wax applicator, showing two states of a pushing element. FIGS. 1A-B show various embodiments of the components of the wax applicator.

[0129] As can be seen for example in FIG. 1B, The wax applicator 1 comprises: a wax chamber 10 having an opening 103; a heating element 20 attached to the wax chamber 10, configured to heat at least a portion of the wax in the wax chamber 10, thus giving rise to melted wax; and a pushing element 30 configured to push the melted wax out of the wax chamber 10 through an opening 103 the opening.

[0130] According to one embodiment, shown in FIGS. 1A-B, the wax chamber 10 comprises one opening 102. The opening 102 allows insertion of wax into the wax chamber 10, and opening 103 allows exit of melted wax from chamber 10. The opening 103 allows insertion of wax into the wax chamber 10, and exit of melted wax from the wax chamber 10. According to another embodiment, the wax chamber 10 comprises multiple openings 102, 103, for example two openings 102, 103a first opening and a second opening. For example, the first opening 102 is configured to allow insertion of wax into the wax chamber 10, and the second opening 103 is configured to allow exit of melted wax from the wax chamber 10.

[0131] According to some other embodiments, the wax chamber 10 comprises an opening 102 that is configured to allow insertion of wax into the wax chamber, and an opening 103 that is configured to allow exit of melted wax from the wax chamber 10. The opening 102 that is configured to allow insertion of wax into the wax chamber 10 includes a cover (not shown) configured to open for the insertion of wax into the wax chamber 10, and to close while the wax is heated within wax chamber 10. The cover may be configured to slide between open and closed configurations. The cover may include a hinge configured for rotation between open and closed configurations. The cover may be configured to seal opening 102 when in a closed configuration and/or to prevent the spillage and/or leakage of wax from wax chamber 10. Optionally, the cover may include a locking mechanism. Optionally, the locking mechanism may prevent opening of the cover while the applicator 1 is in use and/or the wax is melted and/or heating element 20 is active. Optionally, the locking mechanism may be a magnet, and/or a catch, and/or a fastener.

[0132] According to one embodiment, the wax chamber 10 is configured to accommodate any type of wax, particularly wax that is used for hair removal. The way may be solid wax in any size and shape, for example wax bars, wax flakes, capsules, and the like. Additionally, or alternatively, the wax in a paste-like texture, for example partially melted wax; or liquid wax with a honey like texture, for example fully melted wax. The partially melted wax and the fully melted wax are obtained by heating solid wax.

[0133] The heating element 20 that is attached to the wax chamber 10 is configured to heat the wax that is in the wax chamber 10, thus giving rise to melted wax. Any type of heating element 20 is under the scope of the present subject matter. The heating element 20 is configured to heat the wax, and thereby melt the wax, namely cause the wax to be in a paste-like texture, or in liquid form. Since the melting temperature of most types of wax is substantially 40 C., or above, the heating element 20 is configured to heat the wax that is in the wax chamber 10 to a temperature of at least substantially 40 C.

[0134] According to one embodiment, the wax chamber 10 is configured to keep melted wax inside the wax chamber 10 in a melted state for an extended period of time, also without needing to heat the melted wax. In other words, the wax chamber 10 is configured to keep high temperatures inside it for an extended period of time, for example substantially 10-15 minutes. This can be achieved, for example, by an embodiment according to which the wax chamber 10 is made of a heat insulating material. According to some embodiments, is that the wax chamber 10 is closed, and therefore loss of heat from inside the wax chamber 10 is greatly eliminated. This feature of the wax chamber 10 allows saving energy, since there is no need to operate the heating element 20 constantly in order to keep the wax in the wax chamber 10 in a melted state.

[0135] Referring now to FIG. 2, schematically illustrating, according to an exemplary embodiment, a back perspective view of a wax applicator. FIG. 2 shows external components of the wax applicator 1.

[0136] According to one embodiment, a component of the wax applicator 1 is electrically operated, and the electrically operated component is electrically connected to an electrical power supply. Any type of electrical power supply is under the scope of the present subject matter, for example, mains electricity, an electrical power source, like any type of electrical battery such as a disposable battery, a rechargeable battery, and the like.

[0137] According to one embodiment, the electrical power supply is the mains electricity, and the wax applicator 1 is configured to electrically connect to the electricity mains, for example with an electrical cord and plug. Thus, as shown in FIG. 2, according to another embodiment, the wax applicator 1 further comprises an electrical socket 40 electrically connected to the electrically operated component of the wax applicator 1, and is configured to electrically connect to the electricity mains, for example, with a cord and plug.

[0138] According to another embodiment, the electrical power supply is an electrical power source 55, shown in FIGS. 4B-C, hereinafter. Thus, according to this embodiment, the wax applicator 1 further comprises an electrical power source 55 electrically connected to the electrically operated component of the wax applicator 1. According to yet another embodiment, when the electrical power source 55 is rechargeable, like a rechargeable battery 55, the rechargeable power source 55 is electrically connected to the electrical socket 40.

[0139] According to one embodiment, the heating element 20 is an electrical heating element 20. Thus, according to this embodiment, the heating element 20 is electrically connected to an electrical power supply. When the electrical power supply is the electricity mains, the electrical heating element 20 is electrically connected to the electrical socket 40; and when the electrical power supply is an electrical power source 55, the electrical heating element 20 is electrically connected to the electrical power source 55.

[0140] Returning now to FIG. 1B. According to one embodiment, the wax applicator 1 further comprises a thermostat 25 and a temperature sensor 27 configured to sense a temperature of wax in the wax chamber 10, wherein the thermostat 25 is electrically connected to the heating element 20, and the temperature sensor 27 is signally connected to the thermostat 25. The temperature sensor 27 is configured to sense the temperature of the wax that is in the wax chamber 10 and transmit a signal indicative of the sensed temperature to the thermostat 25. The thermostat 25, in its turn, is configured to compare between the sensed temperature and a predetermined threshold temperature and accordingly switch-on or switch-off the heating element 20. When the sensed temperature is lower than the threshold temperature, the thermostat 25 is configured to allow operation of the heating element 20, or switch-on the heating element 20. When the sensed temperature is higher than the threshold temperature, the thermostat 25 is configured to switch-off the heating element 20. Thus, this embodiment ensures that the wax that is in the wax chamber 10 is kept at a predetermined threshold temperature, and that the temperature of the wax in the wax chamber 10 does not raise above the threshold temperature.

[0141] Returning now to FIG. 2. According to one embodiment, the wax applicator 1 further comprises an on-off switch 42 electrically connected between the electrical power supply and the electrically operated component. When the electrical power supply is the electricity mains, the on-off switch 42 is electrically connected between the electrical socket 40 and the electrically operated component of the wax applicator 1. Alternatively, when the electrical power supply is the electrical power source 55, the on-off switch 42 is electrically connected between the electrical power source 55 and the electrically operated component of the wax applicator 1. The on-off switch 42 is configured to allow switching-on and switching-off operation of components of the wax applicator 1, for example operation of the heating element 20, or operation of other components that will be described hereinafter.

[0142] Still remaining in FIG. 2, according to one embodiment, the wax applicator 1 further comprises a temperature setting switch 28 electrically connected to the thermostat 25 and configured to allow determination of the threshold temperature. For example, as can be seen in FIG. 2, the wax applicator 1 comprises two temperature setting switches 28, one temperature setting switch 28 for increasing the threshold temperature, and another temperature setting switch 28 for decreasing the threshold temperature. It should be mentioned, though, that this embodiment is only exemplary. Any type of mechanism for determining the threshold temperature is under the scope of the present subject matter.

[0143] Still remaining in FIG. 2, according to one embodiment, the wax applicator 1 further comprises a display 29. The display 29 is configured to display parameters indicative of the operation of the wax applicator 1. For example, the display 29 is configured to indicate whether the heating element 20 is on or off, indicate the predetermined threshold temperature, indicate the sensed temperature of the wax in the wax chamber 10, indicate status of the electrical power source 55for example a level of charging of the rechargeable power source 55, indication whether there is a need to replace or charge the electrical power source 55, and the like. Additional parameters that can be displayed in the display 29 will be described hereinafter.

[0144] The pushing element 30 is configured to push melted wax that is in the wax chamber 10, and force exit of the melted wax through the opening 103 as described above. Any type of pushing element 30 is under the scope of the present subject matter. For example, according to one embodiment, the pushing element 30 is a kind of piston. Thus, the piston-like pushing element 30 is configured to be pushed inside the wax chamber 10, thereby push melted wax from the wax chamber 10 through the opening 103.

[0145] According to one embodiment, the pushing element 30 is manually actuated. Thus, according to this embodiment, the wax applicator 1 further comprises a manual actuator for manually actuating the pushing element 30, for example in a form of a trigger that is mechanically attached to the pushing element 30. Manually pressing the trigger causes movement of the pushing element 30 inside the wax chamber 10. Alternatively, the manual actuator can be in a form of an outer knob that is attached to the pushing element 30, and configured to be manually pushed, thereby causing movement of the pushing element 30 inside the wax chamber 10. It should be noted that the aforementioned embodiments are only exemplary embodiments of the manual activator, and they should not be considered as limiting the scope of the present subject matter.

[0146] According to another embodiment, the wax applicator 1 further comprises a motor 50 mechanically attached to the pushing element 30, and configured to actuate the pushing element 30. Any mechanism for actuating the movement of the pushing element 30 by the motor 50 is under the scope of the present subject matter. The motor is shown in FIGS. 4A-C, hereinafter, and an exemplary embodiment of the mechanism of actuation of the pushing element 30 by the motor is illustrated in FIGS. 1A-B.

[0147] Returning now to FIGS. 1A-B. FIGS. 1A-B schematically illustrate two states of the pushing element 30, optionally actuated by a motor. FIGS. 1A-B show a pushing element 30 in a form of a piston. In FIG. 1A, the pushing element 30 is in a fully pulled position, mostly distant from an opening 103 that allows exit of melted wax from the wax chamber 10. In FIG. 1B, the pushing element 30 is in a fully pushed position, mostly adjacent to the opening 103 that allow exit of melted wax from the wax chamber 10. Thus, the pushing element 30 is configured to be pushed and pulled between these two positions, either manually, or with a motor 50, as mentioned above.

[0148] An exemplary mechanism for pushing and pulling the pushing element 30 by the motor 50 is described in the following embodiment. The motor 50 is shown in FIGS. 4A-C hereinafter. According to one embodiment, seen in FIGS. 1A-B, the wax applicator 1 further comprises a screwed shaft 35 positioned between the motor 50 and the pushing element 30. The motor 50 is configured to turn the screwed shaft 35 in two directions - clockwise and counterclockwise. When the screwed shaft 35 is turned in one direction, for example clockwise, the screwed shaft 35 is pushed forward and thereby push the pushing element 30 in the wax chamber 10 toward an opening 103 that allows exit of melted wax from the wax chamber 10, as seen in FIG. 1B. This, in turn, causes exit of melted wax from the wax chamber 10 through the opening 103 that allows exit of meted wax. On the other hand, when the screwed shaft 35 is turned in an opposite direction, for example counterclockwise, the screwed shaft 35 is pulled backward and thereby pull the pushing element 30 in the wax chamber 10 away from the opening 103 that allows exit of melted wax from the wax chamber 10, as seen in FIG. 1A. This position of the pushing element 30, shown in FIG. 1A, allows insertion of wax into the wax chamber 10. It should be noted, though, that this mechanism for actuating the pushing element 30 by the motor 50 is only exemplary, and should not be considered as limiting the scope of the present subject matter.

[0149] According to one embodiment, the motor 50 is an electrical motor 50. Thus, similarly to the heating element 20, the motor 50 is electrically connected to the mains electricity, for example through the electrical socket 40, shown for example in FIG. 2, and/or to the electrical power source 55, shown for example in FIG. 4C. According to another embodiment, the wax applicator 1 further comprises a direction switch 52 configured to control the direction of the turning of the motor 50, thereby controlling the direction of movement of the pushing element 30, as shown in FIG. 2. According to yet another embodiment, the wax applicator 1 comprises two direction switches - one direction switch 52, when actuated by a user, prompts operation of the motor 50 in a manner that pushes the pushing element 30 forward, thus causing exit of melted wax from the wax chamber 10; and another direction switch 52, when actuated by a user, prompts operation of the motor 50 in a manner the pulls the pushing element 30 away from the opening 103 that allow exit of melted wax from the wax chamber 10. In another embodiment, the display 29 is configured to display the direction of movement of the pushing element 30.

[0150] According to a further embodiment, the wax applicator 1 further comprises a speed switch 54, also shown in FIG. 2.

According to yet a further embodiment, the display 29 is additionally configured to display, in the display 29, the speed of movement of the pushing element 30.

[0151] Referring now to FIG. 3, schematically illustrating, according to an exemplary embodiment, a side perspective view of a wax applicator. FIG. 3 particularly shows a wax application head 60 attached to the wax applicator 1. According to one embodiment, the wax applicator 1 further comprises a wax application head 60 configured to attach to an opening 103 that allows exit of melted wax from the wax chamber 10, and allow passage of the melted wax through the wax application head 60. According to one embodiment, the wax application head 60 is hollow, and comprises an attachment portion 62 at one side of the wax application head 60, configured to attach to the opening 103 that allows exit of melted wax from the wax chamber 10, and a nozzle 64 at an opposite side of the wax application head 60, configured to allow application of a controlled amount of the melted wax on the skin of the user. Thus, when the wax application head 60 is attached to the opening 103 that allows exit of melted wax from the wax chamber 10, and when the melted wax is pushed out of the wax chamber 10 by the pushing element 30, the melted wax enters into the wax application head 60, passes through the wax application head 60, and exits through the nozzle 64.

[0152] According to one embodiment, the wax applicator 1 comprises a set of multiple wax application heads 60. The attachment portion 62 of the wax application heads 60 is similar in all the wax application heads 60, in order to allow attachment of all the wax application heads to the opening 103 that allows exit of melted wax from the wax chamber 10. On the other hand, the size and shape of the nozzle 64 of the wax application heads 60 is different in each wax application head 60. This allows a user to apply the melted wax on the skin of the user in various amounts and textures of the applied melted wax, as well as to adjust the amount and texture of the applied melted wax to the area of the skin on which the melted wax is applied, simply by changing the wax application head 60 that is attached to the opening 103. For example, a wide and big nozzle 64 allows application of a large amount of melted wax over a wide area of the skin, while a narrow and small nozzle 64 allows application of a small amount of melted wax over a narrow area of the skin.

[0158] In some embodiments, a wax capsule 205a may have the form of a cylinder with a circular cross section. Alternatively or additionally, the capsule 205b may be tapered. For example, the back 209 side of the capsule 205b may taper away from the wax emitter opening. In some embodiments, the taper of the capsule 205b may reduce sticking and/or residue on the sides of the chamber of the applicator. For example, as the wax is pushed out of the applicator the back 209 end of the capsule may be crushed and/or spread outward. The tapered shape of the capsule may inhibit the spreading of the back 209 of the capsule causing the wax to be pressed against the walls of the chamber that as the capsule is pushed towards the emitter head. Alternatively or additionally, the capsule 205c may have a cylindrical shape with a non-circular cross section. For example, capsule 205c has a D-shape with a flat dorsal 310 face towards door 208 and a convex ventral 211 side bulging into chamber 203. Additionally or alternatively, the dorsal 310 side of the capsule 205c (e.g., facing the door 208 outward from the chamber 203) may be convex and/or concave (e.g., with a larger radius of curvature than the ventral side 211). For example, the radius of curvature of the ventral 211 side of the capsule 205c may be less than 8 mm and/or of between 3 to 7 mm. For example, the radius of curvature of the dorsal 310 face may be greater than 10 mm and/or greater than 20 mm. Optionally, the ventral 211 side of the capsule may be faceted (e.g., the cross section may be a polygon (e.g., a hexagon and/or a rectangle)) and/or irregular shape (e.g., curved with a changing radius of curvature and/or an irregular polygon). For example, the cartridge may have a vertex and/or a minimum radius of curvature at the center line of the ventral 211 face thereof. Optionally, the ventral face 211 of the capsule may fit the inner wall of chamber 203 and/or the capsule 205c may be self-orienting when inserted into the chamber 203. Additionally or alternatively, a capsule may be tapered with a non-circular cross section.

[0159] According to some embodiments, the opening 207 that is configured to allow insertion of wax into the wax chamber 203 includes a cover 208 configured to open for the insertion of wax into the wax chamber 203, and to close while the wax 205 is heated within wax chamber 203.

Optionally, the cover 208 may include a locking mechanism. Optionally, the locking mechanism may prevent opening of the cover while the applicator 199 is in use and/or the wax is melted and/or heating element is active. Optionally, the locking mechanism may be a magnet, and/or a catch, and/or a fastener.

[0160] According to one embodiment, the wax chamber 203 is configured to accommodate any type of wax, particularly wax that is used for hair removal. The wax capsule 205a, 205b, 205c may include solid wax in any size and shape, for example, wax bars, wax flakes, wax pellets, wax capsules, and the like. Additionally, or alternatively, the wax may have a paste-like texture, for example, partially melted wax; or liquid wax with a honey-like texture, for example, fully melted wax. The partially melted wax and/or the fully melted wax are obtained by heating the wax. The partially melted wax and/or the fully melted wax are obtained by heating solid wax. The wax may be configured as a capsule 205a, 205b, 205c. The wax chamber 203 may be shaped to fit the wax capsule 205a, 205b, 205c. For example, for capsules (e.g., capsules 205b, 205c) with asymmetric shapes, the chamber 203 and/or the insertion opening 207 may be designed to encourage proper alignment of the capsule 205b, 205c. The wax capsule 205a, 205b, 205c may include bare wax.

[0161] In some embodiments, the wax capsule 205a, 205b, 205c may be wrapped with a wrapping material. The wrapping material may be resilient and/or configured to protect the wax prior to use. The wrapping material may be removed, at least in part, from the capsule prior to insertion into the wax chamber. The wrapping material may be meltable on heating of the wax, e.g., the wrapping material may melt at the temperature used to melt the wax on heating by the heating element within the wax applicator. The wrapping material may be soluble in the wax, e.g., the wrapping material may dissolve in the wax on heating of the wax to a liquid or semi-liquid state. The melted and/or dissolved wrapping material may not affect the function of the wax and/or its physical properties. Alternatively or additionally, the wrapper may remain in the chamber of the applicator. For example, the wrapper may be crushed as the capsule 205a, 205b, 205c is use and/or as the pusher advances. In such a case, the tapered capsule 205c may have an advantage over the cylindrical capsules 205b, 205c. For example, as the wrapper of the tapered capsule is crushed it may form a substantially flat disk and/or allow more complete ejection of the wax. Alternatively or additionally, the wrapper may be in the form of a cartridge. For example, the cartridge may include a hollow cylinder whose interior is filled with the wax and/or whose exterior fits the shape of the wax chamber of the applicator. Optionally, the pusher of the wax applicator passes through the cartridge and/or pushes the wax out of the cartridge. Optionally, when the wax is finished the cartridge remains intact in the surround chamber of the applicator. After use the pusher may be retracted and/or the empty (or partially empty) cartridge may be removed.
