Shower cap

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.

1 . A cap device for providing warmth to the head of a person, comprising:
 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,   
   
   
       2 . The device of  claim 1 , wherein the crystalline compound is calcium oxide. 
   
   
       3 . The device of  claim 2 , wherein the calcium oxide is calcined prior to forming the crystalline mixture and the crystalline material further includes a zeolite in a ratio of from about 14 to 20 for calcium oxide and from about 7 to 10 for powdered zeolite. 
   
   
       4 . The device of  claim 3 , which further includes a quantity of exotherm delaying material coating the heat source to slow down the penetration of the actuation agent. 
   
   
       5 . The device of  claim 4 , wherein the exotherm delaying material is a polyalkyl glycol. 
   
   
       6 . The device of  claim 5 , wherein the polyalkyl glycol is polyethylene glycol. 
   
   
       7 . The device of  claim 3 , wherein the amount of calcium oxide and zeolite is sufficient to cause the cap liner to reach a controlled temperature of up to 130° F. 
   
   
       8 . The device of  claim 1 , wherein the crystalline compound is granular and is dispersed between the liner and the inside of the cap. 
   
   
       9 . The device of  claim 1 , wherein the crystalline compound is contained in a pouch having a breakable seal to permit water to contact the compound. 
   
   
       10 . The device of  claim 9 , wherein the pouch is located between the inside of the cap and the liner contacting the inside of the cap. 
   
   
       11 . The device of  claim 9 , which further includes a package for containing the cap and wherein the pouch is located in the package for activation prior to removal of the cap therefrom. 
   
   
       12 . A cap device for providing warmth to the head of a person, comprising:
 outer cap means for providing a water impervious outer surface and sized to fit over the hair of a person;   liner means located inside the outer cap means for contacting the hair of a person; and   heat source means for producing an exothermic reaction with water,   
   
   
       13 . The device of  claim 12 , wherein the heat source means is calcium oxide that is calcined prior to forming the crystalline mixture and the crystalline material further includes a zeolite in a ratio of from about 14 to 20 for calcium oxide and from about 7 to 10 for powdered zeolite. 
   
   
       14 . The device of  claim 13 , which further includes a quantity of exotherm delaying material coating the heat source to slow down the penetration of the actuation agent. 
   
   
       15 . The device of  claim 14 , wherein the exotherm delaying material is polyethylene glycol. 
   
   
       16 . The device of  claim 13 , wherein the amount of calcium oxide and zeolite is sufficient to cause the cap liner means to reach a controlled temperature of up to 130° F. 
   
   
       17 . The device of  claim 12 , wherein the crystalline compound is granular and is dispersed between the liner means and the inside of the cap means. 
   
   
       18 . The device of  claim 12 , wherein the crystalline compound is contained in a pouch having a breakable seal to permit water to contact the compound. 
   
   
       19 . The device of  claim 18 , wherein the pouch is located between the inside of the cap and the liner contacting the inside of the cap. 
   
   
       20 . The device of  claim 18 , which further includes a package for containing the cap and wherein the pouch is located in the package for activation prior to removal of the cap therefrom.
