  • a hair-removing tweezer device having resilient tweezer legs for removing unwanted facial and other body ha by heat electrically generated at the outer ends or tips of the tweezer legs as a result of the hair being squeezed between the outer ends or tips of the tweezer legs, said tweezer legs being in the form of a pair of resiliently- closeable electrodes of stainless steel or other such electrically * conductive material adapted to be connected by an electrical lead to a suitable source of electrical power for heating the outer ends or tips of the tweezer legs and insulated from each other in an electrically insulated hand for a user to hold when the tweezer device is in use -and tipped at the outer ends with tungsten carbide or other suc highly electrically resistant material for generation of a suitable degree of hea.t at the outer ends or tips of the tweezer legs wh.en the outer ends or tips of the tweezer leg meet by pressing the twee
  • the present invention provides a portable electrical appliance adapted to be battery operated or electrical power point operated at home or else where by a user for the removal of unwanted facial and othe body hair, said appliance comprising a hair-removing tweezer device having resilient tweezer legs for removing unwanted facial and other body hair by heat electrically generated at the outer ends or tips of the tweezer legs as a result of the hair being squeezed between the outer ends or tips of the tweezer legs, connected by an electrical lea to an electric battery or to an electrical transformer hous in a casing, the electrical transformer having an electrica lead for connection to an electrical power point mains supp said tweezer legs being in the form of a pair of resilientl closeable electrodes of stainless steel or other such ** electrically conductive material insulated from each other in an electrically insulated handle for the user to hold when the tweezer device is in use and the outer ends of the tweezer legs tipped with tungsten carbide or other such highly electrically resistant material
  • the outer ends or tips of the tweezer legs have pads or inserts of tungsten carbide or other such highly electrically resistant material, forming the inner opposite surfaces for contacting engagement when the tweezer legs are pressed together for the purpose.
  • Said pads or inserts may be flat or plane-faced however in a further preferred embodiment, the contacting surfaces of the pads or inserts at outer end or tips of the tweezer legs are serrated for sawtooth-point engagement, so that a hair is more effectively gripped by the contacting serrations.
  • a safety device is incorporated in the electrica circuit whereby the electrical supply to the tweezer legs i automatically cut-off should said legs inadvertently stay closed together or should said legs be accidently placed on an electrically conductive material which closes the electrical circuit; and/or an electrical overload protectio device is incorporated in the electrical circuit whereby th electrical supply is automatically cut-off should an electrical overload occur in the operation of the tweezer device.
  • The. electrical energy supply to the tweezer device preferably is such that an electrical current of about 1-5 amperes can pass between the outer ends or tips of the tweezer legs wh.en they meet ' by pressing the tweeze legs so as to close the outer ends or tips together, and the electrical circuit preferably incorporates a resistor say of 2.5 ohm ' s to provide for the electrical energy suppl to the tweezer legs to have a minimum and a maximum settin within the range of 1-5 amperes, more suitably within the range of 2-4 or 2-3 amperes.

  • AC alternating current
  • direct current power sources in providing for an electrical current of about 1-5 amperes to pass between the outer ends or tips o the tweezer legs in order to heat the outer ends or tips o the tweezer legs to the requisite degree for the purpose indicated.
  • Use of AC electrical power source with an electrical transformer is preferred since it can be accomm dated in a smaller housing and thus provide a smaller size * portable, appliance, without over--heating problems, and is relatiyely cheaper to produce.
  • tweezer legs and/or pads or inserts which are too small can have insufficient electrical resistance, with the result that insufficient heat is created for the purpose of the invention, whilst, on the other hand, tweezer legs and/ or pads or inserts which are too large, can have excessive electrical resistance, with the result that excessive heat is created.
  • the electrical power supply needs to be adjusted to suit the size and nature of the tweezer legs and/or the size and nature of the pads or inserts.
  • a setting of 1-5 amperes can be used, the preferred setting is 2-3 amperes-
  • the hair has to be held for a much longer period in order for the hair to b freed from the follicle, whereas at a setting of 5 amperes the hair can be freed very quickly.
  • Tweezer legs having pads or inserts at the outer ends with serrated opposite surfaces for sawtooth engagemen is desirable since coarse or thick hair may prevent the electrical circuit from closing, hair being a non-conductiv fibre and a coarse body hair could prevent the tips or pads from meeting.
  • the points of the serration can meet more or less regardless of the thickness of the hair, making it possible for the electrical circuit to close effectively.

  • Fig. 6 is a plan view of a serrated pad or inser shown in Fig. 5.
  • the hair-removing tweezer device 1 has resilient tweezer legs 2 in the form a pair of resiliently-closeable electrodes of stainless st or other such electrically conductive material, connected an electrical lead 3 to a suitable source of electrical power for heating the outer ends or tips 4 of the tweezer legs 2 and insulated from each other in an electrically insulated handle 5 for a user to hold when the tweezer device 1 is in use.
  • the outer ends or tips 4 of the tweez legs 2 have pads or inserts 6 of tungsten carbide or other such highly electrically resistant material for generation of a suitable degree of heat when the outer ends or tips 4 of the tweezer legs 2 meet by pressing the tweezer legs 2 together for h ⁇ purpose indicated.
  • Electrically insulated handle 5 conveniently consists of a rubber protective cover 7, enclosing the inn end portions of the stainless steel tweezer legs 2, said inner end portions being set in an epoxy resin body 8 whic is held in a polytetrafluoroethylene cap 9.
  • Nickel/silver wires 10 join the inner ends of the stainless steel tweeze legs 2 to the connecting ends of the electrical lead 3 by silver soldering or brazing, the opposite ends of the electrical lead 3 being fitted to a plug 11 -for plugging i a terminal 12 in the casing 13 which houses an electric battery or an electrical transformer adapted to be connect to an electrical power ' point mains supply.
  • Casing 13 which houses the electrical battery electrical transformer, is in miniaturised console form, t back of the console having a terminal to receive a plug-in electrical lead 14 when electrical mains supply is used vi the electrical transformer.
  • the front of the console casi 13 is provided with a contact-button 15 for switching-on o switching-off the electrical connection between the electr battery or the electrical transformer and the tweezer devi and a signal-light 16 to indicate when the tweezer device actively switched-on to the electrical battery or the electrical transformer, as well as the plug-in terminal 1 for connecting the tweezer device to the electrical batte or the electrical transformer.
  • Figs. 1-3 of the drawings illustrate a tweezer device 1 in which the tweezer legs 2 have flat or plane- faced pads or inserts 6 of tungsten carbide or other such highly electrically resistant material
  • Fig. 5-6 of the drawings illustrate a tweezer device 1 in which the tweezer legs 2 have serrated-faced pads or inserts 6A of tungsten carbide or other such highly electrically resista material.
  • Pads or inserts 6/6A may be silver soldered or brazed to the outer ends of the tweezer legs 2 in either instance.
  • the appliance In use, the appliance is adjusted to apply appr priate electrical power to the tweezer device 1 and a hair is firmly held between the pass or inserts at the outer en of the tweezer legs 2. After about 1-2 seconds, the hair comes away by the root without any sensation of pain. Removal of a number of hairs on the upper lip, which is a very sensitive area was effected in this way, and it was possible to remove the hair and root without apparent pain or discomfort.
  • the appliance of the invention is simple to use by a person; provides for home treatment; an is simple to produce.
  • Stainless steel is the preferred electrically conductive material for construction of the tweezer legs 2, since the denseness of that material localizes the heat generated at the outer end or tips 4 of the tweezer legs 2,
  • a suitable portion of the length of each said tweezer legs 2 may be provided with a coating or sleeve of any appropriat heat/electrical insulating material.
  • Tungsten carbide is the preferred electrically resistant material for the construction of the pads or inserts 6 at the outer ends or tips 4 of the tweezer legs 2 since that material is highly electrically resistant, and relatively easily attached to the outer ends or tips 4 of tweezer legs 2, and is readily serrated for the formation serrated pads or inserts 6, and is relatively economical t employ for the purpose.
  • Nichrome alloy and titanium metal are other electrically resistant materials that might be used in place of tungsten carbide, however, nichrome alloy" is much less preferred since it does not readily lend itself to serrating for the formation of serrated pads or inserts 6, and flat or plane-faced pads 6 are inclined to stick to each other when heated and pressed together, whil titanium metal is much less preferred since it is highly costly.
