BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Features and advantages of the present invention will become apparent to those skilled in the art from the following description with reference to the drawings, in which:

[0013] FIG. 1 depicts a side view of an embodiment of the instant invention.

[0014] FIG. 2 depicts a bottom up view of the embodiment of FIG. 1.

[0015] FIG. 3 depicts a side view of a prior art shower cap.

[0016] FIG. 4 depicts a bottom up view of a prior art shower cap.

DETAILED DESCRIPTION OF THE INVENTION

[0017] Referring to the drawings, FIG. 1 depicts a side view of the improved shower cap. The shower cap has a pull string 200, a string closer 300, a lower band covered with an overlay 100, and a hair protecting bag 400. The overlay 100 protects the inner band and the head of the user. FIG. 2 shows a bottom up view of the shower cap, the pull string 200, a string closer 300, and overlay 100 enclosing a string. In some embodiments, enclosed in the overlay is an elastic band. The hair protecting bag 400 is preferably made out of a water-proof or water-resistant material of sufficient gauge/firmness that it retains its form without the need for ribs or wires. Polycarbonate PC with a thickness of 0125 MM and other materials containing about and near some of the following the physical properties of gravity g/cm3 ASTM D792 1.2 and Water absorption % ASTM D570<0.40 and Mechanical Tensile strength MPa ASTM D882>55 and Elongation at Break % ASTM D882>90 and Young's modulus MPa ASTM D790 2000 and Thermal performance of the thermal expansion coefficient Cm/cm ° C. ASTM D696 7×10-5 and Thermal conductivity of W/m.Math.K ASTM C117 0.19 and Shrinkage % ASTM D1204<0.3 (135° C.) and Brittle transition temperature ° C. ASTM D746-130 and Vicat softening point ° C. ASTM D1525 150 and Flame retardant—UL-94 V-2 and Electrical Properties Dielectric strength kV/mm ASTM D149 30 and Dielectric constant 60 HZ/100 HZ ASTM D150 2.98/2.95 and Surface resistivity Ω ASTM D257>1×1015 and Volume resistivity Ω.Math.cm ASTM D257>1×1016 and Arc resistance sec ASTM D495 have proven effective, but any material that is comfortable and has the water-resistant and shape conforming characteristics may be used. These characteristics only show particular desired embodiments and a wide range of attributes could easily be substituted for other embodiments of the invention. In some embodiments of the invention, the hair protecting bag 400 is able to surround a volume fifty percent or greater than the volume of the hair style intended to be protected. The hair protecting bag 400 is ideally large enough to avoid contact between the shower cap and the hair to prevent the shower cap altering the hair style while protecting the hair from the elements (e.g. heat, water, wind, dust and other contaminants, processes and things that might alter the hair or its styling).

[0018] Referring to the drawings, FIG. 3 depicts a side view of a prior art shower cap. The shower cap has a lower ridge 500. FIG. 3 depicts a bottom up view of the prior art shower cap it shows the lower ridge 500 is formed from an inner elastic band 600. The invention improves upon the prior art by using the overlay 100 to protect the user's head from the ridge 500 and reinforcing the bottom edge of the shower cap. It also provides a channel for the adjustable pull string 200. By adjusting the pull string the user is enabled to adjust the tension of the lower ridge 500 around the user's head. The overlay 100 may be made out of any comfortable material, but an anti-microbial and preferably water proof material should be used. The larger hair protecting bag 400 of an antibacterial/antifungal self supporting shape conforming material replaces the need in the prior art for more expensive ribs or wire to maintain the shape of the shower cap. Having a uniform surface 400 for the hair protecting bag and an overlay 100 for the bottom ridge makes the improved shower cap, amongst other things, more effective, easier to manufacture, clean and reuse.

[0019] Thus, it is seen that the objects of the present invention are efficiently obtained, although modifications and changes to the invention should be readily apparent to those having ordinary skill in the art, which modifications are intended to be within the spirit and scope of the invention as claimed. It also is understood that the foregoing description is illustrative of the present invention and should not be considered as limiting. Therefore, other embodiments of the present invention are possible without departing from the spirit and scope of the present invention.
