Abstract
The invention provides a method and an apparatus which assure a sustained vaporization of deodorants, perfumes, pest control agents and other substances intended to modify, condition on otherwise alter the atmosphere. A tape comprising a base material and, as supported thereon, at least one active substance which vaporizes at ambient temperature or under heating in a condition in which its vaporization is inhibited is driven relative to a head which is adapted to remove the inhibition of vaporization, whereby the active substance is vaporized at a constant rate.
Claims16
A method of vaporizing active substances which comprises driving a tape comprising a base material and, as carried thereon, at least one active substance which vaporizes at ambient temperature or under heating in a condition in which the vaporization thereof is inhibited relative to a head adapted to remove the inhibition of vaporization to thereby vaporize said active substance in a position where said tape contacts or approaches said head.
An apparatus for vaporizing active substances which comprises a tape comprising a base material and, as carried thereon, at least one active substance which vaporizes at ambient temperature or under heating in a condition in which the vaporization thereof is inhibited, a head adapted to remove the inhibition of vaporization thermally, physically or chemically, and a drive means adapted to drive said tape relative to said head.
