11 Claims.

This invention relates to certain improvements in hair waving pads for use where a pre-formed tress of hair is subjected to the action of an exothermic material contained within the pad, which exothermic material whenmoistened will, of itself, generate heat sufficient to impart a socalled permanent wave to the pre-formed tress.

My improved hair waving pad comprises an outer wrapper, an envelope containing an exothemic material and having a perforated face, a sealing flap folded over and removably adhered to the perforated face of the envelope for sealing its perforations, an absorbent sheet adapted to be placed upon the perforated face of the envelope after the sealing flap has been stripped therefrom, and an inner flap adapted to be folded over onto the moistened absorbent sheet.

The object of my invention is to produce a hair waving pad of the above character in which the step 0 perforating the envelope containing the exothermic material immediatelybefore the application of moisture thereto, is eliminated, thus permitting the pad to be shipped with the face of the envelope already perforated and temporarily sealed.

Practical embodiments of my invention are represented in the accompanying drawing, in which:

Fig. 1 represents an inside plan view of one form of pad;

Fig. 2 represents 'a similar view of another form of pad;

Fig. 3 represents a similar view of a third form I of pad; and

Fig. 4 represents a similar view of a fourth form of pad.

The outer wrapper 1 of the pad is shown as comprising a once folded sheet of impervious material, such for instance as parchment paper, foil, or the like.

The envelope 2 which contains the exothermic material 3, such for instance as calciumoxid in powdered form, has its face perforated as shown at 4. This envelope is also of impervious material, such for instance as foil.

A flap 5 of impervious material, as foil, is folded over and adhered to the perforated face of the envelope 2 for temporarily sealing the perforations 4. The sealing adhesive may be of some suitable material, such it. instance as petroleum jelly, which will not injuriously affect the pre-formed hair tress or the exothermic action of the material within the envelope, when the pad is in use.

A sheet 6 of absorbent material is shown as a flap projecting from the pad in position to be moistened and then folded over onto the perforated face of the envelope 2 after the sealing flap 5 has been stripped from the perforated face of the envelope.

A sheet 7 of impervious material, such. for instance as foil, is interposed between the envelope 2 and the outer wrapper 1, which sheet is shown as extended to produce a flap 8 adapted to be folded over onto the flap 5 after the moistened flap 6 has been folded over onto the perforated face of the envelope and the sealing flap 5 has been folded over onto the moistened flap 6. This flap 5 may form an extension of the sheet 7.

In the form shown in Fig. 1, the flap 8 is perforated and the sealing flap 5 unperforated, the perforations in the flap 8 being denoted by 9. In the form shown in Fig. 2, the inner flap 8 is shown as unperforated and the sealing flap 5 is shown as perforated, the perforations 10 being out of alinement with the perforations 4 of the envelope 2. In the form shown in Fig. 3, the inner flap 8 and the sealing flap 5 are both unperforated. In the form shown in Fig. 4, both the inner flap 8 and the sealing flap 5 are shown as perforated.

These different forms permit the more or less direct action of the heat on the pre-formed tress when the pad is in use.

In practice, the pre-formed tress of hair, not shown herein, may be moistened either before or after it is wound, with a suitable hair waving solution. The inner flap 8 is turned back and the sealing flap 5 is stripped from the perforated face of the envelope containing the exothermic material. The absorbent flap 6 ismoistened and folded over onto the perforated face of the envelope. The inner flap 8 and the sealing flap 5 are then folded over onto the moistened flap 6. The pad is then wrapped around the pre-formed tress in the usual manner and the exothermic action starts at once. Heat is thus set up within the pad sufficient to impart a so-called permanent wave to the pre-formed tress without requiring application of heat from an outside source.

From the above description it will be seen that by sealing the perforated faces of the envelopes containing the exothermic material the pads may be shipped in quantities and the emthermic material protected from deterioration by exposure tovarying atmospheric conditions until the time comes for using the pads. When it is desired to use the pads, the sealing flaps are stripped from the perforated faces of the envelopes, as above described.

The form of pad shown and described in Fig. 4, in which the inner flap and the sealing flap are both perforated, forms the subject matter of my divisional application filed March 3, 1933, Serial No. 659,475.

It is evident that various changes may-be resorted to in the construction, form and arrange- 4 ment of the several parts without departing from the spirit and scope of my invention, and hence I do not wish to be limited to the particular embodiments herein shown and described, but
