Tamper-resistant container utilizing a flexible seal

A tamper-resistant volatile material dispenser comprising an open-ended container having a peripheral flange surrounding an open end having a bottom surface and side walls, with at least one flexible sealing layer attached to a top surface of said peripheral flange to form an interior region wherein at least one sealing layer is permeable to a volatile material enclosed within said interior region, and having a least one integral free-standing rib extending upward from the bottom surface of said container within said interior region to a level approximately coextensive with said peripheral flange, but not attached to said flexible sealing layer said container being impermeable to said volatile material.

In combination, a tamper-resistant volatile material dispenser comprising an open-ended container having a peripheral flange surrounding an open end having a bottom surface and side walls, with at least one flexible sealing layer attached to a top surface of said peripheral flange to form an interior region wherein at least one sealing layer is permeable to a volatile material enclosed within said interior region, and having at least one integral free-standing rib extending upward from the bottom surface of said container within said interior region to a level approximately coextensive with said peripheral flange, but not attached to said flexible sealing layer, said container being impermeable to said volatile material;

• and an electrically heated vapor dispensing apparatus constructed and arranged to receive said open-ended container and whereby said apparatus heats said volatile material contained in said container causing said volatile material to diffuse into the surrounding atmosphere.
