The invention relates to an epilating apparatus, a cooling/heating pad for an epilating apparatus, and a cooling/heating pad add-on kit for an epilating apparatus.
An epilating apparatus comprising an auxiliary member for cooling the skin is for example known from WO-A-00/76363. With the known epilating apparatus hairs are mechanically extracted from the skin. The hair removing member of the known epilating apparatus comprises a series of clamping discs which are rotatably supported in an epilation head. During rotation of the clamping discs the clamping discs are tiltable in pairs, from a hair catching position, in which hair catching spaces are present between the pairs of clamping discs, to a clamping position in which the pairs of clamping discs are clamped against each other near their edges. Hairs that penetrate the hair catching spaces when the clamping discs are in the hair catching positions are subsequently clamped between the clamping discs and extracted from the skin under the influence of the rotating movement of the clamping discs.
The auxiliary member of the known epilating apparatus is provided with a skin contact element and a holder which is in thermal contact therewith. In the holder there is provided a substance having a comparatively high cold capacity. The auxiliary member is detachably coupled to a main housing of the hair removing device. Before using the hair removing device, the substance should be cooled to a comparatively low temperature by placing the auxiliary member, for example, in a refrigerator for some time. If the auxiliary member is coupled to the main housing, the skin contact element is situated, viewed in a direction wherein the hair removing device is to be displaced over the skin, directly in front of the hair removing member. Consequently, during displacing the hair removing device over the skin, the skin is first cooled by the auxiliary member and immediately after that treated by the hair removing member.
By previously cooling the skin the pain that is usually felt when hairs are extracted is masked. This masking effect can be attributed to the fact that pain stimuli generated during extracting the hairs by pain receptors present around the hairs, are only partially passed on via the nervous system because said nervous system is partially blocked to pain stimuli by the cold stimuli already present in the nerves system and generated by the cold receptors present around the hairs. By virtue of this masking effect the extraction of hairs is experienced as considerably less painful.
A similar pain reduction can be reached by heating the skin before it is treated. Additionally or alternatively it is also possible to cool or heat the skin after treatment. This also reduces the pain and can, for example, be realized by mounting the auxiliary member behind the epilating area with reference to the moving direction.
However, there is a problem in that the known auxiliary member and therefore the whole known epilating apparatus is costly. The known attempts to heat the skin before treatment are also costly.
It is therefore the object of the invention to provide a cheaper possibility for cooling/heating the skin to be treated.
The above object is solved by an epilating apparatus comprising a compartment for receiving a cooling/heating pad. The compartment accommodates the pad in such a way that, when the epilating apparatus is in an operating position relative to the skin, the pad is at least partially in direct or indirect thermal contact with the skin. As regards the compartment, such a compartment can be formed within a stiff overall housing, for example between a main body and a rigid sleeve attached thereto. However, it is also possible that the compartment is provided within a flexible bag-like housing which is intended to receive a state of the art epilating apparatus having no cooling/heating means and a separate cooling/heating pad. In such a case the flexible bag-like housing can, for example, be made of a textile or the like and can also function as a connector for the state of the art epilating device and the cooling/heating pad.
At least during use of the epilating apparatus it is preferred that a cooling/heating pad is removably arranged within the compartment. The term cooling/heating pad is intended to cover any member that does not comprise a completely rigid or substantially undeformable housing or covering portion, but comprises a cushion-like member having a deformable or flexible housing or covering portion accommodating a heating or cooling medium. The deformability or flexibility of the cooling/heating pad is an important advantage, because it allows a better contact of the cooling/heating pad with the skin during operation, so that cooling/heating of the skin is improved when the cooling/heating pad is directly in contact with the skin during operation. It is also possible that a core of the cooling/heating pad is surrounded at least partially by a flexible material to form the cooling heating pad. Furthermore, the cooling/heating pad can be insulated at least partially. For example, the cooling/heating pad can be made of a welded plastic foil which at least partially is filled by a cooling/heating medium having a comparatively high cold/heat capacity. Such a cooling/heating pad can be produced significantly cheaper than the known cooling members, and therefore the total costs are reduced. As with the known epilating apparatus mentioned at the beginning, the cooling/heating pad should be cooled to a comparatively low temperature by placing the cooling pad, for example, in a refrigerator for some time, before the epilating apparatus is used. Alternatively, the cooling/heating pad can be placed, for example, in a microwave, if it is desired to heat the skin before treatment to reduce the pain.
With preferred embodiments of the epilating apparatus in accordance with the invention, the cooling/heating pad comprises a bag portion containing a cooling/heating medium and a fixing portion for fixing the cooling/heating pad within the compartment. Also in this case the whole cooling/heating pad can, for example, be made by suitably welding a plastic foil. Of course it is also possible that the cooling/heating pad is formed without welding, for example by molding. It is preferred that the dimensions of the cooling/heating pad are at least essentially adapted to the dimension of the compartment. It is further preferred, but not mandatory, that the fixing portion contains no cooling/heating medium.
It is preferred for the epilating apparatus in accordance with the invention that the fixing portion of the cooling/heating pad at least partially is a flat portion. In such a case the fixing portion is preferably arranged within a handle portion of the epilating apparatus, wherein the flat fixing portion makes it possible to keep the dimensions of the handle portion so small that the handle portion can be gripped easily.
With highly preferred embodiments of the epilating apparatus in accordance with the invention, the cooling/heating pad contains a cooling/heating medium which comprises a gel. In such a case the cooling/heating pad can be referred to as a gel pad. Gel pads as such are known to be suitable for cooling or heating, for example, parts of the body, particularly in case of an injury. Any gel known to the person skilled in the art in this connection can be used as cooling/heating medium for the cooling/heating pad.
Furthermore, it is preferred that a ledge provided in the compartment interacts with the fixing portion of the cooling/heating pad. The ledge can, for example, be a bolt that extends through a hole provided in the fixing portion of the cooling/heating pad and additionally connects different parts of the epilating apparatus, for example a main body and a sleeve. In such a case the fixing portion of the cooling/heating pad can be clamped between the sleeve and the main body. It is also possible, that the fixing portion of the cooling/heating pad comprises no hole, but is fixed by clamping only.
In accordance with a further development of the epilating apparatus in accordance with the invention the compartment is formed between a main body of the epilating apparatus and a sleeve. The sleeve can, for example, be a plastic part which preferably also forms at least a section of the handle of the epilating apparatus. For example, the ledge mentioned above and provided in the compartment can be capable for securing the sleeve to the main body. However, this is not compulsory and the sleeve can be attached to the main body in any suitable manner. If the ledge is provided on the sleeve, it can, for example, engage into a recess provided in the main body. Such a connection can be made, for example, by force and/or form closure. Furthermore, it is preferred that the sleeve is movable with respect to the main body. The sleeve can be completely detachable or movable via, for example, a sliding or hinging movement. If the sleeve is movable with respect to the main body, it is easier to remove and insert the cooling/heating pad.
With preferred embodiments of the epilating apparatus in accordance with the invention the sleeve at least partially comprises an insulation. Such an insulation on one hand keeps the cooling/heating pad cool/hot for a longer period and on the other hand guarantees that the hands do not become to cold/hot during use of the epilating apparatus. Any suitable insulation material can be used for this purpose, for example, plastic foams, polystyrene and the like.
Particularly in connection with add-on kits it is also possible that the compartment is formed within pick-up means surrounding the epilating apparatus at least partially. In such a case the epilating apparatus in accordance with the invention is formed by a state of the art epilating apparatus comprising no compartment and the pick-up means.
Furthermore, it is preferred for the epilating apparatus in accordance with the invention, that the cooling/heating pad comprises an active cooling/heating portion arranged adjacent to an active epilating portion. The active cooling/heating portion is preferably arranged to directly contact the skin. It is also possible, that the active epilating portion is surrounded completely or at least in part by the active cooling/heating portion. In such a case it is also possible to use more than one cooling/heating pad, for example one on each side of the active epilating portion.
To solve the above object, the invention also provides a cooling/heating pad for an epilating apparatus, wherein the cooling/heating pad comprises a bag portion containing a cooling/heating medium and a fixing portion for fixing the cooling/heating pad to the epilating apparatus. Such a cooling/heating pad is suitable to be used with the epilating apparatus described above. As already mentioned, the cooling/heating pad can, for example, be made of a welded plastic foil. In any case the cooling/heating medium should have a comparatively high cold/heat capacity to store a sufficient amount of cold/heat. As regards the cooling/heating pad and the preferred embodiments thereof mentioned below, reference is again made to the above description, to avoid repetitions.
With preferred embodiments of the cooling/heating pad in accordance with the inventions, the cooling/heating medium comprises a gel. In such a case the cooling/heating pad can be referred to as a gel pad.
In accordance with a further development of the cooling/heating pad in accordance with the invention, the fixing portion comprises at least one recess intended to receive at least one ledge of the epilating apparatus.
Furthermore, it is preferred for the cooling/heating pad in accordance with the invention that the fixing portions at least partially is a flat portion.
The invention is also directed to a cooling/heating pad add-on kit for an epilating apparatus, the cooling/heating pad add-on kit comprising a cooling/heating pad and pick-up means for removably picking up the cooling/heating pad and the epilating apparatus. For example, it is possible that a compartment for receiving the cooling/heating pad is provided within a bag which is further intended to receive a state of the art epilating apparatus having no cooling/heating. The bag can be a flexible bag, for example, be made of a textile or the like. Alternatively, it is possible that the bag is made from a relative stiff material like plastic. The pick-up means can function as a connector for the state of the art epilating device and the cooling/heating pad.
