Apparatus for delivering a volatile material

An apparatus for delivering a volatile material comprising a delivery engine comprising:

• a. a liquid reservoir comprising a volatile material mixture, said mixture comprising about 90% to about 100%, by total weight of said mixture, of volatile materials each having a VP at 25° C. of less than about 0.3 torr;
• b. a rupturable substrate secured to said reservoir;
• c. a compressible flange positioned adjacent to said rupturable substrate for rupturing said rupturable substrate;
• d. a collection basin in fluid communication with said liquid reservoir upon rupturing said rupturable substrate;
• and
• e. a microporous, ultra-high molecular weight polyethylene membrane enclosing said liquid reservoir, said rupturable substrate, said compressible flange, and said collection basin, wherein said membrane comprises a silica filler, an average pore size of about 0.01 microns to about 0.06 microns, and a thickness of about 0.01 mm to about 1 mm.

An apparatus for delivering a volatile material comprising a delivery engine comprising:

• a. a reservoir comprising a volatile material mixture;
• b. a rupturable substrate secured to said reservoir;
• c. a rupture element;
• d. a microporous membrane enclosing said reservoir, said rupturable substrate,
• and said rupture element;
• wherein said rupturable substrate is position subjacent said rupture element and said rupture element is positioned subjacent said microporous membrane, and wherein, when said rupturable substrate is breached by actuating said rupture element, said volatile material mixture passes transversely through said rupturable substrate and said rupture element and contacts said breathable membrane for diffusion to the atmosphere.
