Patent ID: 6994270

Claim:
A semi-enclosed gel system for release of volatile materials, wherein the dimensions of the gel system, in the x, y, and z dimensions, are such that: x i /y i >1.5, a. H i /z i >2.0, b. x F /y F >2.0, c. d. ⁢ ⁢ ( A D ) ⁢ ⁢ final / ( A D ) ⁢ ⁢ initial ( A P ) ⁢ ⁢ final / ( A P ) ⁢ ⁢ initial > 0.19 , wherein: A D =Surface Area of the gel that is directly exposed to ambient flowing air A P =Area available for permeation of vapors generated within the enclosure e. ⁢ ⁢ ( A D ) ⁢ ⁢ final ( A D ) ⁢ ⁢ initial > 0.65 , and f. ⁢ ⁢ ( AP ) ⁢ ⁢ final ( AP ) ⁢ ⁢ initial < 4.0 , wherein: x i =the longest dimension measured in the x direction of the projection of the directly exposed region of the gel system in the x-z plane at the initiation of volatilization; y i =the longest dimension measured in the y direction of the projection of the directly exposed region of the gel system in the x-y plane at the initiation of volatilization; z i =the longest dimension measured in the z direction of the projection of the directly exposed region of the gel system in the x-z plane at the initiation of volatilization; H i =the longest dimension measured in the z direction of the projection of the entire gel system in the x-z plane at the initiation of volatilization; x F =the longest dimension measured in the x direction of the projection of the directly exposed region of the gel system in the x-z plane at the end of volatilization; y F =the longest dimension measured in the y direction of the projection of the directly exposed region of the gel system in the x-y plane at the end of volatilization; z F =the longest dimension measured in the z direction of the projection of the directly exposed region of the gel system in the x-z plane at the end of volatilization; and H F =the longest dimension measured in the z direction of the projection of the entire gel system in the x-z plane at the end of volatilization.
