ABSTRACT: A skin massaging and stimulating method wherein a sheet or mitt is formed of a poromeric, coriaceous material (corfam) and is useful per se, or in conjunction with cosmetic compositions, The coriaceous material serves to effect massaging and removal of dead skin when moved across the skin.
INVENTOR. uoyo MOTZ A 7' TORIVEYJ' DERMATOLOGICAL COSMETIC PROCESS This invention relates to a method of using dermatological cosmetic apparatus and, more specifically, to an improved cosmetic sheet or mitt structure formed of a poromeric material for massaging a subjects skin, either per se or in conjunction with a cosmetic preparation.
It is an object of the present invention to provide improved skin massaging and more specifically, an object of the present invention is employing cosmetic massaging and applicator apparatus, formed of a poromeric material, which is extremely soft to the touch while being sufficiently abrasive to efi'ect massaging and dead skin removal; and which is extremely durable and capable of retaining its form and utility over a prolonged period of use.
The above and other objects and features of the present invention are realized in specific illustrative embodiments thereof presented hereinbelow in conjunction with the accompanying drawing in which:
FIG. 1 depicts a cosmetic mitt employing operative poromeric surfaces of the type shown in FIG. 2.
FIG. 2 illustrates in greatly expanded form a representation of an operative poromeric surface employing the principles of the present invention.
Referring now to FIG. 2, there is shown in greatly expanded employed as an applicator.
Poromeric skin-treating apparatus can also be fabricated in laminar fonn to have active surfaces on each exposed side thereof. For example, referring now to FIG. 1, there is shown a cosmetic mitt formed of two poromeric planar sheets each having 'an exposed outer surface 11 and an inner surface 12.
. The two sheets are joined at the periphery thereof, with the form a surface portion 20 of a poromeric material, such as Corfam (a trademark of the DuPont Corporation). Poromeric materials, and Corfam in particular, are nonwoven coriaceous sheets comprising a urethane polymer base reinforced with polyester.
The upper Corfam portion 20 comprises a urea foam and, I
for the present application, advantageously comprises a suede or otherwise matted surface wherein the upper urea foam is characterized by sharp and hard, but very small edges 21. Such a Corfam surface may be purchased directly from the DuPont Corporation or prepared for example, by sharply crosscutting or mechanically buffing a poromeric sheet.
The poromeric material in FIG. 2 may be employed per se in sheet or other form as a skin-massaging cosmetic apparatus. The active surface 11 of the material feels extremely soft and pleasant to the skin while the small, but sharp and durable urea edges 21 locally stimulate the skin and enhance the circulation therein. Also, the poromeric surface 11 abrades and removes dead skin and scale during the mechanical massaging operation.
Alternatively, the Corfam material illustrated in FIG. 2 can be used in conjunction with cosmetic preparations as an applicator therefor, e.g., as a powder pull to apply facial powder or the like. The poromeric material serves as a good carrier and applicator for such preparations and, moreover, performs space between the sheets being adapted to accommodate a user's hand for manipulation purposes. The two outer poromeric surfaces 11 are formed as the like-numbered surface in FIG. 2, and the inner surface 12 may be the Corfam backer or, alternatively, any desired liner material selected for aesthetic or utility purposes. The mitt 10 can be used to massage and stimulate a subject's skin per se or to do so while applying any cosmetic preparation.
The two planar poromeric sheets may be joined to form a mitt 10 by any conventional method such as sewing, gluing or the like. Alternatively, these surfaces may be joined by placing the edges thereof into an abutting relationship and directing a stream of ultrasonic energy transversely through the laminate. The ultrasonic energy will be principally dissipated at the discontinuity where the surfaces join, with the expended energy producing heat which locally melts and fuses t e poromeric layers. This ultrasonic method for joining the Corfam layers is disclosed in a copending application of Messrs. H. R. Jacobsen and E. W. Jensen, Ser. No. 718,938, filed Apr. 4, 1968.
Each of the above-described poromeric durable cosmetic structures is extremely durable, and thereby exhibits a prolonged serviceable life. Also, the poromeric material may be washed or otherwise cleaned periodically without harming its useful properties. I
It is to be understood that the above-described concepts are only illustrative of the principles of the present invention. Numerous other arrangements and modes of operation may be devised by those skilled in the art without departing from the spirit and scope of the present invention.
What I claim is:
l. A method for cosmetically treating skin area comprising rubbing-a nonwoven coriaceous sheet material comprising a urethane polymer base reinforced with polyester against said skin.
2. A method as in claim 1 wherein said polyester reinforced urethane polymer material includes a matted surface.
3. A method as in claim 1 wherein said polyester reinforced urethane polymer material comprises sueded Corfam.
4. A method as in claim 1 further comprising the step of impregnating said polyester reinforced urethane polymer material with a cosmetic preparation prior to said rubbing step.
