STATES PATENT OFFICE 2,116,079 SACHE‘T‘ FOR ‘TREATING AND' WAVING ' HAIR Pierre Lucien Moulin, Paris, France, assignor to Eugene, Ltd., New York, N. Y_., a corporation of New York‘ Application March 21, 1936, Serial No. 70,154 In Great Britain March 23, 1935 5 Claims. This invention relates to the permanent Waving» and similar treatment of hair and particularly to the practice of applying sachets or treating pads to hair tresses wound and stretched upon curling rods carried by hair clamps preparatory to the application of heat. In the conventional practice the tress is ?rmly clamped near the scalp and after winding the tress upon the curler and vmounting the curler 10 with the tress wound thereabout upon the clamp, the sachet or other treating pad is applied upon 15 20 2 30 3 .10 and over the wound tress and the ends of the pad pinched about the sides of the wind for the treating operation. Irrespective of the care exercised in positioning and applying the sachet, the under side of the wound tress, namely, that portion adjacent the clamp, is either imperfectly contacted or not contacted at all by the treating pad and an imperfect closure of the win-d is obtained with the result that the wound tress is non-uniformly treated and leakage of the hot fluid and vapors often occurs with injury to the scalp. Moreover, when external heaters are employed the latter sometimes burn the exposed or imperfectly shielded tress. One of the objects of the invention is the eirective closure, protecting and treating of the wound hair tresses, whereby the whole circumference of the wound tress is intimately contacted by the treating pad with resultant uniform treating and waving of the tress. A further object is to effect a, Substantially complete enclosure of the wound hair tress within the sachet or treating pad, notwithstanding the mounting of the curlers upon the suppgrting clamps, whereby the whole circumference of the wound tress is uniformly treated and leakage in the neighborhood of the unwound part of the tress near the roots avoided, A further object of the invention is ‘a novel sachet or treating pad for use in hair waving. Further objects of the invention will hereinafter appear. .

Fig. 8 is a perspective view of the pad Shown in Fig. 7. Referring to the drawing the scalp is indicated 15 at A and tress of hair to be waved and treated is indicated at B. A COI1Vehti0nal hair clamp 01‘ protec'wl‘ is indi cated at I, the details of which are omitted from the drawing for convenience in illustration, it “o being of any conventional type for ?rmly clamp ing the tress of hair B Heal“ the scalp- The Clamp or protector l carries the conventional curler or T001 2, the latter being Carried by the holders or lugs 3 mounted on the clamp. At 4 is indi- 25 Gated the sachet or treating pad for enclosing the Curler rod having a tress of hair Wound there abollli- A Protecting Dad 01" Shield 5 of rubber, felt 01‘ the like is disposed beneath the Clamp l and preferably this protecting pad 5 is separate 30 from the clamp l, although the clamp l is often itself provided with a rubber or felt protector on its under Side FigS- 1 and 2 Show the tress of hair wound ready fOI‘ treatment. It is noted that in addition 35 t0 the pl‘?tectihg Shield 01‘ pad 5 GiSDOSBd beneath the Clamp l, the Satchet 01‘ treating pad 4 eXtendS between the clamp l and the curler carrying the wound tress B, leaving no part Of the Wind ex posed and thereby forming a double seal or pro- 40 tection against the hot vapors and ?uid reaching the scalp- MOI‘BQVBI‘, the sachet Completely eh circles and encloses the Whole circumference of the wound tress of hair which ensures a thorough and uniform treatment of the Wound tress. 45 Figs. 3 t0 6- When a protecting Dad 5 Sepa rate from the clamp is utilized it is ?rst threaded upon the tress 13, this Pad usually having a Slit or opening in it for the reception of the tress. The clamp I is then caused to grip the tress at a 50 point adjacent the pad 5. The sachet or treat ing pad 4 is provided with a transverse slit 4’ intermediate its ends and edges, as indicated, for the reception of the tress in a closely ?tting man ner. The sachet is threaded over the tress and '55 2 2,1 16,079 brought down upon the clamp l with the tress passing through the slit 4'. Fig. 4 illustrates a convenient way of threading the tress through the slit 4', when the slit is closed at both ends and stops short of both sides of the pad as illus trated, a hook 6 being employed in this operation. The tress is then wound from the tip towards the roots (Fig. 5) upon the curler 2 to form a substantially cylindrical wind, whereupon the 10 curler 2 is then inserted upon the holders 3 of the clamp l. The wind is then tensioned and stretched by applying a key or wrench to the spindle of the curler and turning it in the con ventional manner. The sachet is then brought upwardly from both sides about the wound tress 15 of hair and the ends are caused to overlap as indicated at In and II. The wound tress thus formed and totally enclosed in the sachet 4 is then ready for the application or production of 20 heat utilized in the treatment of the hair It is thus apparent that the whole circumfer ence of the wound tress is brought into efficient hair treating relation with the sachet 4, the lat ter entirely enclosing the wound tress. A uni 25 form and thorough treatment of the hair tress is thereby effected. Moreover, the wound tress, being entirely enclosed within the sachet itself, is thoroughly shielded against and protected from any other part of the appliance, such as a con 30 ventional heater clamped thereto. The internal heat is maintained and preserved more efliciently and the vapors and liquids cannot escape and drip upon or burn the scalp. The slit or ori?ce 4’ is so dimensioned as to afford passage ex 35 actly to the tress of hair and is effectively sealed by the tress of hair passing therethrough thus preventing the escape of vapors or ?uid along the unwound root part of the tress. For more effec tively forming the seal at the slit the latter may be reinforced as, for example, by absorbent elas tic material so that on the tress of hair being drawn through the slit the material adjacent the slit may be pressed down for the purpose of tightly clamping the hair tress at the position at 45 which it extends through the sachet. Thus the body of the sachet 4 rests against the underneath side of the wound tress and directly in contact with the clamp protector or support or in con tact with another protecting layer which rests 50 upon the clamp. The sachet is wrapped around the curler and tress of hair from the bottom' and away from the scalp contrary to the conven tional practice of wrapping the sachet from the top of the wind and only partially encircling the 55 wind. In the preferred practice of the invention the sachet is inserted with the tress passing through the slit 4', as the next step immediately follow ing the clamping of the tress by the clamp I and, 60 as indicated above, the tress may be passed through the slit 4' by the use of a suitable instru ment or hook 6. In the particular embodiment illustrated, the sachet or pad is adapted to the accommodation of a single tress of hair, but, 65 obviously, if more than one tress of hair is to be treated by the use of the same pad the latter should have for best results a slit for each tress. The sachet 4 may otherwise be of any conven tional character. For example, it may comprise 70 an outer envelope 12 of thin metal foil, piece of tinsel or a sheet of material that is a good conductor of heat, an absorbent lining l3 of soft, thick flannel or cotton or otherwise spongy, 76 ?brous or napped material, and ?nally an inner shield M of parchment paper or equivalent sheet material which is perforated or provided with a multiplicity of small pin point holes l5. These parts may be fastened together by seams Hi to form a unitary structure. The absorbent lining l3 serves the usual purpose in hair waving, name ly,—it may be impregnated or soaked in advance or at the moment of operation upon the hair by a liquid or a paste or any other substance which will facilitate that operation. It may be dipped in the vaporizable solution for use in 10 the hair waving operation. This solution does not come into direct contact with the tress of hair B, wound around the curler since the per forated layer I4 retains the liquid which permits the vapors from the liquid to pass through the 15 numerous small openings, thereby forming jets of vapor which penetrate the tress of hair for treat ment. The tress of hair is usually moistened in advance by any suitable material which together with the vapors passing through the perforations 20 from the absorbent layer results in the proper treatment of the hair. The paper shield [4 may, if it be necessary, be extended to form an insert between the soft thick piece [3 and outer_ en velope I2 of the sachet 4 and this part of the 26 paper need not be perforated. Where an external heater is clamped around the curler and the wound tress for applying heat externally, as for example as shown in Fig. '7, the sachet is preferably provided underneath with 30 skirts or ?ange pieces I9, 20 disposed on the opposite sides of the slit for the purpose of shield ing the unwound part 2| of the tress extending between the slit and the clamp from the heat of the heating elements. These protecting skirts l9, 35 20 project between the heater jaws 22 on the one hand and the tress 2i and clamp on the other hand and thus prevent the heater jaws from touching the tress of hair at the point where it comes through the slit 4' or effectively insu 40 late the jaws. These protecting skirts or ?ange pieces of the sachet may be formed in any suitable manner, as by folds of its envelope I2 alone, or by folds of this envelope and the absorbent lining I3 and 45 of its shield 14, as shown. The two superposed folds l9 and '20 form two double lips, triple lips, or quadruple lips, more or less opened out, which are disposed between the hair and the jaws 22 of the heater. Preferably, the protecting skirts 50 form an integral part of the envelope l2, the ab sorbent lining l3, and the paper shield M. The whole may be made as shown in Fig. 8 in such wise as to form an X structure with a central slit 4’ for the passage of the lock of hair. Two 55 groups or separate parts 23 and 24 are secured together face to face along the line 25, as by clips 26 to leave a slit 4’ for the passage of the hair tress and the shorter parts or edges l9, 2!] form the protecting skirts. 60 The two ends of the envelope 12 of the wrapper or sachet may be of different areas, in order that the one of them may be pulled down to the neigh borhood of the base of the other for the purpose of enclosing the wrapper that is pressed down by 65 the jaws 22 of the heater. It is this form of con struction of the sachet which Figure 6 shows diagrammatically. While a heater having the jaws 22 is shown for applying heat externally to the sachet, it is under 70 stood that the invention is not limited to this method of heating, as any conventional method of developing or applying heat in the hair waving art may be employed. Likewise, the invention is not limited to the particular type of curler or 76 2,116,079 clamp as any conventional appliance may be used which includes means; for tensioning the coiled tress and locking the curler on the clamp against uncoiling. The sachet may be varied in construc tion, according to conventional practice within the limitations described above. I claim: 1. A sachet pad for use with a ?at clamp in treating and waving hair in the croquignole proc 10 ess comprising two separate, identically con structed parts fastened together face to face along a line adjacent one edge with the fastening means discontinued through a part of the width to form a slit for the reception of a tress of hair, 15 the short projecting ends forming protecting skirts to overlie the clamp and underlie the jaws of a croquignole heater when placed about the wound tress. 2. A sachet pad of the character set forth in 20 claim 1 which comprises an inner absorbent pad disposed between an outer metallic foil and an inner ?nely perforated parchment paper with the metallic foil projecting at one end beyond the absorbent pad for forming a closed tube about 25 a cylindrical wind. 3. A sachet pad for treating and waving hair in the croquignole process having absorbent ma- 7 terial disposed between a metallized paper and 3 a perforated paper shield, with a double fold formed therein and with the double fold forming two lips with a slit in the center line of junction, the ends of the sachet pad situated to either side of the slit being adapted to be folded about a cylindrical wind in overlapping fashion, the double fold forming skirts which insulate the jaws of the heaters from the hair and head. 4. A sachet pad for use in the croquignole proc ess having a transverse slit formed intermediate the ends thereof for accommodating the insertion of a sachet pad about a flat band of hair and having protecting skirts ?rmly attached to it, said skirts extending from either side of the cen ter line of the slit through which the flat band of hair passes, and being adapted to be disposed between the heater elements and that portion of a tress of hair between the clamp and the wind. 5. A sachet pad for treating and waving hair having a transverse slit formed intermediate the 20 ends thereof to accommodate‘ the passage of a lock of hair therethrough prior to the hair being coiled on the curler, whereby said pad may be rolled up over itself after the wind is formed about the curler and in such manner as to form a 2 complete protective and treating tube thereabout.
