Apparatus for delivering a volatile material

摘要

An apparatus for delivering a volatile material in a continuous manner is disclosed. The apparatus includes a delivery engine having a reservoir for containing a volatile material; a rupturable substrate secured to the reservoir; a rupture element positioned adjacent to the rupturable substrate; and a breathable membrane enclosing the reservoir, rupturable substrate and rupture element. In some embodiments, the apparatus includes a housing having a notch for compressing the rupture element and breaching the rupturable substrate as it is inserted into the housing.

1. An apparatus for delivering a volatile material comprising:
a. a delivery engine comprising:
i. a reservoir for containing a volatile material mixture;ii. a rupturable substrate secured to said reservoir;iii. a rupture element positioned adjacent to said rupturable substrate; andiv. a microporous, ultra-high molecular weight polyethylene membrane enclosing said reservoir, said rupturable substrate, and said rupture element, wherein said membrane comprises 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; wherein, when said rupture element is actuated in a first direction towards said reservoir, said rupturable substrate is breached in said first direction and said volatile material mixture crosses through said rupturable substrate and crosses through said rupture element contacting said membrane for diffusion to the atmosphere; and b. a housing comprising a base, a shell, and a hollowed core, said hollowed core comprises a notch for compressing said rupture element upon insertion of said delivery engine in said housing.
