7 Claims. 1

This invention relates to an improved hair curler.

Among the objects of the invention is the provision of an improved hair curler which is comfortable to wear, which is effective in operation, which is easy to use and relatively simple and inexpensive to manufacture.

Further objects will be apparent from the fol-v lowing detailed description of the drawings in which- Fig. 1 is a perspective view of a curler embodying our invention showing it in open position ready to be used;

Fig, 2 is a perspective view of the curler showing it in its initial operating position with the end of the hair gripped between the flap and body portion;

Fig. 3 is a perspective View showing the curler in the final operative position with the hair wrapped thereon and with the curler inclosed" position; 7

Fig. 4 is a sectional view in the direction of the arrows on the line 44 of Fig. 3;

Fig. 5 is a perspective View brokenaway at both ends showing one economical manner in which the curlers maybe made;

Fig. 6 is a perspective view of a modified form of curler in open position;

Fig. '7 is a perspective View of the modified curler showing it in closed position with the hair wrapped thereon; and I Fig. 8 is a perspective view showing an economical manner of manufacturing the modified type of curler.

Our curler is preferably made from a yielding resilient material so that it will be comfortable when worn and for this purpose we may employ rubber, synthetic rubber, vinyl resin or the like.

Referring to the first form of our invention, we have shown a unitary structure made from a tubular piece of rubber. The structure comprises a tubular body portion or mandrel I0,- an integral flap II and a retaining piece or strip I2. The tubular body portion I 0 may be 'perfo'rated as shown at I3 so as to provide ventilation and serves as the support around which'the hair is wound.

The flap II is concave-convex in cross-section so that it may rest flat against the body portion as shown in Figs. 2, 3 and 4. It is integrally connected at one end to the end or the tubular body portion I0 and is extended through the keyhole type of slot l4 formed in the wall of the tubular body portion opposite the point of connection between the body portion and flap. By forming the slotin keyhole fashion it facilitates the insertion of the flap through the opening but at the same time resists or prevents accidental withdrawal thereof. In this connection the flap is preferably slightly narrower through the area which normally projects through the keyhole slot. It will be seen that the flap may be shifted from open position as shown in Fig. 1 to closed position in engagement with the tubular body portion. The flap is of such a length as to extend to or within a short distance from the opposite end of the tubular body portion and the end thereof may be rounded as shown.

The retaining strip I2 is an elongated memberwhen the device is in closed position as shown in in production so that the successive pieces may be inter-fitted together as it will appear from Fig. 5.

As shown in Fig. 5 the curler may be made from a tube of rubber or the like.

relationship. Thus, it will be seen that the keyhole slot I4, perforations I3, retaining means I2, loop I5, and flap II may be die-cut or otherwise formed in the tube. At the inner end of the flap, circular apertures I8 may be provided to form a.

better hinge and also to provide a narrower portion of the flap for extending through the keyhole aperture it. By referring to the right-hand end of Fig. 5, it will be seen that a second hair curler may be simultaneously cut by arranging it in op- A recess I'I corr e- Successive hair curlers may be out from the same tube in opposite posite and inverted relationship to the first one and that the portions of loop l interfit with each other perfectly when out in this manner. Thus, the curlers may be cut from the tube with a minimum of waste material.

After the curlers have been cut in the manner indicated in Fig. 3, they are individually assembled by projecting the flap I through the keyhole opening it in the manner indicated in Fig. 1. When thus assembled the curler is ready for use.

In using the curler, the end of the hair to be curled is gripped between the flap H and the tubular body portion Ill. The curler is then rotated to wind the hair around the body portion and the outer surface of flap In this connection the hair is wound from the free end towards the roots. When thus wound, the retaining strip I2 is then closed in the manner shown in Fig. 3 to retain the hair and curler in position. This is accomplished by grasping the tab IS in the hand, drawing it towards the opposite end of the curler and the loop portion I5 is then caused to encircle the end of the body portion ID.

A modified form of curler in which a separate retaining strip is employed is shown in Figs. 6 to 8. Thus, I have shown a curler having a tubular body portion 2|], an integral fiap 2| and a separate retaining strip in the form of a loop 22. As in the first form of my invention, the parts are made of yielding, resilient material such as rubber, synthetic rubber, vinyl resin or the like. The body portion may be perforated to provide ventilation as shown at 23 and a keyhole opening 24 similar to the opening I4 is provided through which the flap 2| is extended.

The retaining strip or loop 22 extends through the opening 25 between the connected end of flap 2| and the body portion 20. In this connection, the loop is placed over the flap 2| before it is inserted through the keyhole aperture 24. The opposite end of body portion 20 is provided with slots or apertures 26 with which the free end of loop 22 is engageable when in closed position as shown in Fig. 7. i

Flap 2| is preferably of corresponding length to flap II and terminates a short distance from the end of the body portion 2!). Loop 22 is of such a length as to be fully extended or slightl stretched when engaged in the slot 26.

The curlers may be economically cut from a tube in the manner indicated in Fig. 8. Thus, adjacent curler are cut in inverted and opposite relationship with the flaps 2| overlapping each other. Around the connecting portions of the flaps, the apertures 25 are formed so as to provide a reduced hinge portion which will extend through the aperture 24. The curlers may be die-cut from the tube or, if preferred, may be cut in any other manner.

After the tube is thus cut, loop 22 is placed over the connecting end of the flap 2|, and the flap is projected through the loop and through aperture 24, producing the assembled curler as shown in Fig. 6. The curler is used in a similar manner to the first form of curler.

It will thus be seen that we have provided an improved hair curler which is comfortable to wear, effective in operation, easy to use and relatively simple to manufacture. Modifications may be made in the illustrated embodiment of our invention without departing from the invention as set forth in the accompanying claims.
