Watertight swim cap

Abstract

A watertight swim cap has a rear skullcap section which is fabricated of silicone rubber material. The skullcap section is configured to substantially cover the head of a swimmer. A front rim section of the cap is fabricated of a silicone rubber material which is softer than the material used in the skullcap section. The top edge of the rim section is fused to the bottom edge of the skullcap section to form a single integral cap which, when worn by a swimmer, provides a watertight seal between the cap and the head of the swimmer.

1 . A swim cap comprising:
 a rear skullcap section fabricated of silicon rubber material, said skullcap section configured to substantially cover the head of a swimmer, and   a front rim section fabricated of a silicon rubber material which is softer than the silicon rubber material of the skullcap section, the silicon rubber material of the rim section being fused to the silicon rubber material of the skullcap section to form a single integral cap, wherein when the cap is worn by a swimmer, an airtight, watertight seal is formed between the cap and the swimmer.   
     
     
         2 . The swim cap as in  claim 1  wherein the rim section has a top edge which circumscribes the top of said rim section and the skullcap section has a bottom edge which circumscribes the bottom of said skullcap section. 
     
     
         3 . The swim cap as in  claim 2  wherein the rim section extends from the top edge at the forehead of the swimmer to the swimmer's neck, and the skullcap section extends from the bottom edge around the swimmer's head to where the rim section covers the swimmer's neck. 
     
     
         4 . The swim cap as in  claim 2  wherein the top edge of the rim section and the bottom edge of the skullcap section are fused together to form the cap as a single, integral, unitary cap. 
     
     
         5 . The swim cap as in  claim 3  wherein the top edge of the rim section and the bottom edge of the skullcap section are fused together to form the cap as a single, integral, unitary cap. 
     
     
         6 . The swim cap as in  claim 1  wherein the softer silicon rubber material of the skullcap section and the rim section comprise methyl, the silicon rubber material of the rim section comprising more methyl than the silicon rubber material of the skullcap section. 
     
     
         7 . The swim cap as in  claim 6  wherein the cap weight is 0.122 kgs, the silicon rubber material of the rim section having 0.03416 kgs more methyl and the silicon rubber material of the skullcap section having 0.08784 kgs less methyl. 
     
     
         8 . The swim cap as in  claim 3  wherein the softer silicon rubber material of the skullcap section and the rim section comprise methyl, the silicon rubber material of the rim section comprising more methyl than the silicon rubber material of the skullcap section. 
     
     
         9 . The swim cap as in  claim 8  wherein the cap weight is 0.122 kgs, the silicon rubber material of the rim section having 0.03416 kgs more methyl and the silicon rubber material of the skullcap section having 0.08784 kgs less methyl.
