Filed July 19, 1968, Ser. No. 746,182 Int. Cl. A45d 2/14 U.S. Cl. 132-40 3 Claims ABSTRACT F THE DISCLOSURE This invention relates to hair curlers and particularly to a hair curler suitable for use in public beauty salons.

The increased popularity of the use of beauty treatments and cosmetics by the public has led to a rapid eX- pansion of the beauty salon industry. The operators of these salons have sought a hair curler for use in permanent waves and hair sets which would meet the requirements of rapid manipulation and effective holding.

One device which has been used in curling human hair is a curler generally comprising a cylindrical casing formed by a coiled spring, a net surrounding the casing and a brush having bristles projecting radially from a central core said brush being dimensioned to be inserted inside of the casing. When assembled, the brush bristles protrude slightly beyond the casing and serve as spikes to engage the hair as it is rolled upon the casing. This curler has been used by beauty salons because of its simplicity of operation and its good holding ability; but there are shortcomings attendant with its use.

One disadvantage of the curler just described is that the protruding bristles have a tendency to prick the scalp when the curler is secured close to the head. The principal disadvantage in the use of a brush-encased curler in public beauty salons is that it is difficult to sanitize. When used on successive patrons dandmlf and other foreign matter collects on the brush bristles and on the net surrounding the coiled spring thereby producing an un'sanitary condition. Efforts to devise an effective cleaning technique have been unsuccessful. On this basis, some licensing boards for public beauty salons have found the curler objectionable.

The present invention provides a hair curling device which eliminates the problem of sanitizing curlers in public beauty salons because it is disposable, yet it enjoys the advantages of ease of operation and effective holding characteristics.

I provide a hair curler comprising a perforated hollow cellulose tube open at each end and a strip of resilient, sponge-like material fixed at one end to one end of the tube and adapted to pass over hair curled on the tube and have its opposite end inserted in the end of the tube opposite the fixed end of said strip. Preferably, the tube has a plurality of spaced notches formed in one end and the strip of sponge-like material is fixed to the end of the tube opposite the end having said notches. I prefer to provide that the sponge-like materal is foam rubber.

In the foregoing general description of the invention, I have set out certain advantages, purposes and objects of this invention. Other objects, purposes and advantages will be apparent from the following description and the accompanying drawings in which:

FIGURE l is an isometric view of a curler according to my invention with a portion of the curler body broken away to show interior structure;

FIGURE 2 is an isometric view of the curler of FIG- URE l rotated axially degrees and turned end-to-end showing the beginning of the curling operation; and

FIGURE 3 is an isometric view ofI the curler in the same orientation as in FIGURE 2 showing the completed curl on the curler.

Referring to the drawings, I have illustrated a hollow cellulose tube 10 having perforations 12. Preferably the tube 10 is constructed of four-ply paper. The length and diameter of the tube 10 can be of any convenient and desired dimensions although generally the length will be about three inches and the diameter about one inch. Attached to one end 18 of tube 10 is a strip of resilient sponge-like material 14. Preferably the strip of spongelike material 14 isfoamed material such as foamed natural ruber, foamed synthetic rubber, foamed polyurethane, foamed polystyrene and the like. The strip of spong-like material 14 is dimensioned to exceed the length of tube 10 when attached thereto. The preferable amount of excess is about one-half of the tube length. The width of the strip may be as desired but I have found that a width equal to about one-fourth of the circumference of the tube is convenient. The manner and position of attachment of the sponge-like strip 14 to the tube 10 may vary. I have shown one technique in FIG. l. There the sponge-like strip 14 is cemented to the interior surface 11 of tube 10. Preferably the opposite end 16 of the tube 10 from the end 18 to which the sponge-like strip 14 is attached hasv notches 20 formed therein for reasons which will appear below.

The operation of the curler is as follows:

The end of the hair 22 is placed on the tube 10 and rolled around the tube 10. When the curl has been completed, the sponge-like strip 14 is passed over the completed curl. A slight amount of tension is applied to the strip 14 and the end 24 is forced into the open end 16 of the tube 10 opposite its connection with the strip 14. The notches 20 help to prevent slippage of the strip 14. When desired, the end 24 of the strip 14 is removed from the hollow end 16 of the tube 10 and the `hair unwound from the curler. The curler may be disposed of or used repeatedly in the same manner.

The curler of this invention represents an improvement over the curler described in my U.S. Patent No. 2,972,994. That structure is advantageous in that it eliminates the need for removal of the curler between the steps of treating with curling solution and neutralizing during a permanent wave treatment. It also eliminates the undesirable indentation in the hair caused by conventional tie devices on hair curlers. The present invention equally enjoys these advantages with the further advantage of overcoming the problem of slipping of the curler which sometimes occurred with the curler of U.S. Patent No. 2,972,994. The hank of wool described in the patent was not resilient and therefore had a tendency to slip from its frictional engagement inside of the tube. The hair rolled around the tube would then become less tightly curled and the effectiveness of the curling operation would thereby be impaired. The use of a resilient, sponge-like strip in the present invention overcomes that shortcoming.

I claim:

1. A disposable hair curler comprising a perforated hollow paper tube and an elongated strip of resilient, sponge-like material having one end thereof attached to an end portion of said tube, said strip having a length which substantially exceeds the length of said tube such that the free end of said strip may be passed over hair curled on said tube and tucked into one end of said tube frictionally engaging the interior surface of said tube, whereby said resilient, sponge-like material is securely held within the hollow of said tube.
