Definitions

  • the present invention relates in general to hair depilatory devices and methods for removing hair.
  • Wax-based preparations are used to remove body and facial hair and include both cold wax preparations, and hot wax preparations.
  • U.S. Patent No. 5,908,425 discloses a hand-held, manually operated depilatory device which removes hair located along a length of a linear axis.
  • a string-like elongated element is positioned within the frame and hair is engaged and captured by the moving twisted engagement of said element and pulled away.
  • U.S. Patent No. 5,112,341 discloses a hair removal device having multiple- tweezers element arranged to pluck hair by the plucking motion of a set of movable twist tweezers, which work in a continuously repetitive fashion.
  • the hair-plucking element comprises a set of disc-shaped tweezers elements which are in a fixed position, and an interleaved set of disc-shaped movable tweezers elements mounted on a central shaft.
  • the spaces which are formed between the elements are repetitively opened and closed by the sliding motion of the shaft against a cam which drives the movable elements in both directions in relation to the fixed position tweezers in order to trap and pluck out hair.
  • EP 287 976 discloses an epilating appliance having a tweezers arrangement which opens and closes in an oscillating fashion, the tweezers arrangement oscillates in the direction of, and away from, the hand-held supporting device, so that the gripping devices are adapted to approach the skin's surface in a spread apart position for receiving the hair, and when in the proximity of the skin, the gripping devices are movable to the gripping position in which they clamp the hair, and when in the closed condition, the gripping devices withdraw away from the skin and the hair is thus being plucked out in the process. Then, in the range of the retractive position the gripping devices move again to the spread apart position in which hair is ejected and additional cycles of removal of hair may be initiated.
  • hair to be removed is subjected to vibrations at such a frequency and amplitude that they are transmitted to the hair root or to the hair supporting elements in the vicinity of the root, and exert a force or transmit energy at an extent such as to cause the root to disconnect from the surrounding tissue or at least to considerably reduce the degree of its attachment to the surrounding tissue.
  • the term ⁇ disconnect” or “disconnection " is used herein to denote a partial or a total impairment of the connection between the hair root, or any of the hair or hair supporting elements, and the surrounding tissue.
  • Such disconnection is manifested in that the force required to subsequently pluck the hair out of the skin is less than that required in order to pluck the hair prior to subjecting it to vibrations as it is done in accordance with the invention.
  • the result of such disconnection is also manifested in that the plucking action is less painful to the individual as compared to plucking without prior vibration treatment.
  • the disconnection of the root results from one or combination of a direct effect of the mechanical energy transmitted to the roots or to the supporting elements, or as a result of the elevation in temperature of the root or the supporting elements which may be caused by the mechanical energy absorbed thereby.
  • the hair itself to be removed is used as a wave guide to transmit an amount of energy which damages the root and surrounding elements and yields the detachment of the root from the supporting elements, or the detachment of a portion of the supporting elements from the adjacent tissue.
  • tissue damaging force will be used to denote a force created by vibrations which might cause at least one of the following:
  • hair supporting element will be used to denote a structural or physiological supporting component required to support hair and maintain its viability. Hair supporting elements, include in particular the hair follicle, the papilla, the blood supply to the hair, as well as the bulge and the small muscles attached thereto in proximity to the root.
  • hair base may at times be used herein to denote collectively the hair root, hair shaft and hair supporting element.
  • the vibrations transmitted to the hair are at a frequency such as to allow the mechanical wave to travel along the hair and reach the hair base. This frequency is preferably such that with respect thereto the hair essentially behaves like a rigid body.
  • the vibrations are typically in a frequency of 10 Hz to 100 kHz, preferably in the frequency range of 50 Hz to 10 kHz, and most preferably in the range of 100 Hz to 1000 Hz.
  • vibrations transmitted through the essentially rigid hair shaft and over a period of time which depends on the intended amount of energy to be transmitted to the hair base and which in turn may depend on a variety 5 of factors, some of which are detailed below, reaches the hair root and/or a hair supporting element, and then either in direct consequence of the mechanical energy or as a result of heating thereby, the root or any of the hair supporting elements fatigues and disconnects from its surrounding tissue. Thereafter the hair may be free and can either fall out naturally or be easily removed. The greater effect may l o thus either be achieved immediately, or may be achieved after a period of time following the treatment.
  • the removal of hair in accordance with the invention has a number of advantageous results. For one, hair removal is less painful than removal by a single and abrupt plucking motion, as is in hitherto available depilatory devices. In 15 addition, in accordance with the invention, a large proportion of the hair is removed with the roots, while in prior art depilatory devices, hair would very often be torn, i.e. removed without the root. Furthermore, the destructive forces on the hair root and its supporting elements often have a long-lasting effect which, in some cases, may even lead to permanent cessation of hair growth. 20 Thus, the present invention provides a hair removal method comprising:
  • the present invention further provides a hair removal apparatus, operating through hair removal cycles, wherein each cycle starts with gripping of hair to be removed and ends with the release of said hair, the device comprising:

The various steps of the hair removal cycle will be discussed in more detail below.
  • the hair-gripping device should be of a kind that allows tight gripping of the hair at the beginning of the hair removal cycle, and permits its release at the end of the hair removal cycle.

  • the apparatus is designed such that after gripping the hair, and prior to the onset of vibrations, the hair gripping device moves away from the skin, or the skin is pressed in the direction away from the direction of the hair growth, to cause a hair tensioning state with a displacement sufficient to somewhat tension the hair, but to an extent such that would not be painful.
