TUBE FOB PERMANENT WAVING.

Application filed August 6, 1925.

My invention relates to containers for enclosing strands of hair which have been prepared for the heating operation in a permanent waving process.

It is customary in permanent wavin processes to first treat the hair with a so tening solution, aftenwhich the hair is gathered into strands which are wound around and held in a stretched condition upon curler rods. The strands are then prepared for the heating operation, and usually are treated with a softening solution of borax or oil,

which is held therewith by a coverin A container, usually in the form of a tu e, is then secured around each strand and serves to prevent the hot solution from burning the scalp and also to provide what may be termed an ovenv in which the solution is steamed into the strands. It is desirable that such tubes be secured so that they are leak proof, with respect to the scalp, and clamps are generally applied in the effort to effect such a result. The application of clamps requires considerable time which adds materially to the time required for forming permanent waves in the human hair.

An object of my invention is to provide a tube, for enclosing a strand of hair during the heating operation of a permanent wav ing process, which is of such a character that it can be readily secured, in a self-securing and substantially leak proof relation against the strand.

A further object of my invention Is to provide a tube which can be sealed in sub-v stantially leak proof relation with a strand of hair, and which will efficiently distribute heat substantially uniformly to the wound portions of the strand therein which are surrounded by a heater.

Another object of my invention is to provide as an article of manufacture an improved tubular envelope adapted to be telescoped over a wound strand of hair and to transmit heat through its walls to the strand and which will prevent the transmission of an undue amount of heat from the envelope towards the scalp of the patient.

These and other objects will appear in the following specification, in which I describe a specific embodiment of the invention.

In the accompanying drawin s, Figure 1 is a side elevation of a tube em dying my invention; Fig. 2 is a medial longitudinal Serial No. 48,590.

section of the same taken on line 2-2 of F1g. 1; and Fig. 3 is a perspective view of the elements forming the tube as they are associated bular form.

The container, or tube, is preferably formed of sheet material and in the embodiment illustrated, consists of a sheet of paper 10, a sheet of metal foil 11 and another sheet of paper 12. The paper is preferably of the thermal quality of a sheet of writing linen, and the foil is preferably formed of aluminum, or material having a melting point and properties of pliability of a similar nature.

The inner sheet of paper 10 is referably rectangular in outline and one end 13 thereof is folded over the edge of an end of the sheet of aluminum foil 11. The sheet of foil is of substantially the same width as the sheet of paper 10 upon which it is placed and is somewhat longer, thusproviding an end 14 which projects beyondthe sheet 10. The sheet of paper 12 is preferably rectangular in outline and is placed lengthwise across the sheet of foil. The sheet 12 is of such length and is placed so that its sides 15 extend beyond the sides of the sheets 10 and 11, and the end edge 16 thereofis spaced from the folded end of the sheet 10. The end edge 17 of the sheet 12 is preferably in alignment with the end of the sheet 10.

It will be seen that the-sheet of foil is interposed intermediate the sheets of paper, and the sheets are rolled into tubular form with the sheet 10 forming theinterior wall and the sheet 12 forming the exterior wall. The tube is maintained in tubular form by sealing the sides 15 of the sheet 12 together when rolled into overlapping relation. With the sheets secured in such relation a portion 18 of the foil will be exposed intermediate the end 16 of the sheet 12 and the folded end 13 of the sheet 10.

The tube thus formed is moved endwise over a strand of hair which has been previously prepared upon a rod for the heating operation, and with the end 13 of the sheet 1Q jin advance. The folded end 13 will thus enclose the end of the foil adjacent the scalp so that the heat therefrom during the application of the heater will not be objectionable. When the tube is located in the proper position upon the strand, a crimping ust prior to being rolled into tutoql can be applied to the exposed portion strand of hair therein. The tube will thus be sealed against the strand adjacent the scalp and'will be self retaining clue to the inherent ualities of the foil. The paper sheet 10 orms the inner wall of the tube and the portion adjacent the portion 18 of the foil will be crimped therewith, and the hair treating solution will therefore not come in contact with the metal foil.

The sheets of the tube are perforated at 20, referably after the tube is formed, and in t is manner the steam can escape from the tube when the end of the foil 14 is crimped against the strand of hair, or is otherwise closed. I preferabl seal both ends of the tube and cause t e steam to escape from the end adjacent the scalp, because the larger end of the strand will thus be subjected to the escapin steam to accomplish a better waving e ect adjacent the scalp.

The foil provides an oven, which will distribute heat uniformly within the tube when a heater is applied ar und the exterior thereof. The inner and outer walls of the tube are formed of aper with intermediately disposed foil WhlCh is to be rotected from the heater and from the solution with which the hair is treated. It will be seen that I have provided a tube which can be readily ap lied and removed from a strand of hair, and which will distribute heat evenly to the strand so as to obtain the best results from the heating operation.

It will be understood that various changes could be made in the structure described without departing from the spirit of my invention and the scope of the appended claims.
