Abstract
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.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
70 words
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.
Claim 2
Independent Claim
70 words
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.
Claim 3
Dependent Claim
54 words
A method of vaporizing active substances as claimed in claim 1 wherein said active substance is a member selected from the group consisting of deodorants, aromas, antimicrobial agents, insect control agents, air fresheners, attractants, repellents, rust inhibitors, spoilage control agents, drugs for absorption from the respiratory organ, skin or mucosa, and presence effect aromas.
Claim 4
Dependent Claim
22 words
A method of vaporizing active substances as claimed in claim 2 wherein said aromas are scents, phytoncides or aromas for aroma therapy.
Claim 5
Dependent Claim
19 words
A method of vaporizing active substances as claimed in claim 1 wherein the inhibition of vaporization is removed thermally.
Claim 6
Dependent Claim
19 words
A method of vaporizing active substances as claimed in claim 1 wherein the inhibition of vaporization is removed physically.
Claim 7
Independent Claim
67 words
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.
Claim 8
Independent Claim
67 words
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.
Claim 9
Dependent Claim
22 words
An apparatus for vaporizing active substances as claimed in claim 6 wherein said tape is accommodated or accommodatable in a casette case.
Claim 10
Dependent Claim
16 words
An apparatus for vaporizing active substances as claimed in claim 6 wherein said tape is non-endless.
Claim 11
Dependent Claim
16 words
An apparatus for vaporizing active substances as claimed in claim 6 wherein said tape is endless.
Claim 12
Dependent Claim
24 words
An apparatus for vaporizing active substances as claimed in claim 6 wherein said tape is one not to be supplemented with said active substance.
Claim 13
Dependent Claim
24 words
An apparatus for vaporizing active substances as claimed in claim 6 wherein said tape is one that can be supplemented with said active substance.
Claim 14
Dependent Claim
40 words
An apparatus for vaporizing active substances as claimed in claim 6 wherein said drive means includes a supply reel and a takeup reel, whereby said tape is paid out from said supply reel and taken up on said takeup reel.
Claim 15
Dependent Claim
29 words
An apparatus for vaporizing active substances as claimed in claim 6 wherein said drive means includes a drive roll by which said tape is driven relative to said head.
Claim 16
Dependent Claim
34 words
An apparatus for vaporizing active substances as claimed in claim 6 wherein said drive means includes a drive belt driven in contact with the tape, whereby said tape is driven relative to said head.
Claim 17
Dependent Claim
30 words
An apparatus for vaporizing active substances as claimed in claim 6 wherein said tape has an active substance or substances with variegated functions as supported on the base material thereof.
Claim 18
Dependent Claim
35 words
An apparatus for vaporizing active substances as claimed in claim 6 wherein said tape has an active substance or substances with variegated functions as supported on the base material thereof in a plurality of lanes.
