Benefits of technology

[0009]The present invention includes a shower cap or other piece of apparel that is worn to protect the hair or head from water, such as when taking a shower, to eliminate the need to dry wet hair or to preserve a

Problems solved by technology

The major drawback of using a supercooled liquid is that the amount of liquid used is relatively small (to generate just enough and not dangerously high heat) and does not easily contact the entire inside of the cap.

Embodiment Construction

[0016]For the purpose of this invention, the term cap is defined as any of the water impervious caps well known for use in commercial and consumer products. These caps are available in a variety of shapes, sizes, colors and may have designs or images printed or molded thereon. One such cap 11 is shown in FIG. 1 for purposes of illustration in position on a person 13 using the device. FIG. 2 illustrates a plurality of caps 11 in package 14. Cap 11, as is conventional in the industry, includes a liner 15, seen in FIG. 3. The liner 15 contacts the person's head and often serves to prevent contact by the person with the harder outer surface of cap 11.

[0017]The present invention provides a source of exothermic heat that is generated when a heat generating chemical comes into contact with an activating agent. In the prior noted U.S. Pat. No. 6,918,138, an ampoule holding a supercooled liquid is used as a heat source, and the heat is generated when a small crystalline portion of the liquid...

Abstract

A cap device for providing warmth to the head of a person including an outer cap having a water impervious outer surface and sized to fit over the hair of a person, a liner located inside the outer cap, the liner being sized to contact the hair of a person, and a heat source including a crystalline compound capable of exothermic reaction with water. The preferred heat source is calcined calcium oxide and a powdered zeolite in a ratio of from about 14 to 20 for calcium oxide and from about 7 to 10 for powdered zeolite.

Description

BACKGROUND[0001]This invention relates to a cap that can be worn in the shower or other places where the user wished to keep her or his hair from becoming wet. More particularly, the invention relates to shower cap in which an exothermic reaction contained within the cap generates sufficient heat to warm a cleaner and conditioner in the cap to cleanse and condition the users' hair.[0002]Caps that are worn in the shower to keep one's hair dry are not new. Some caps may be made of synthetic materials that are water impervious and may be used in the shower, as a protection from rain, or as a bathing cap for swimming in a pool or other body of water. The cap may be decorated to give added visual appeal.[0003]Shower caps have been modified to include additional features. U.S. Pat. No. 5,987,967 discloses a shower cap with a pouch for long hair. U.S. Pat. No. 5,455,970 discloses a shower cap using an elastic band to maintain the positioning of the cap.[0004]In some instances, it is desira...
