Abstract
Abstract A device for dispensing a vaporizing composition to the surrounding atmosphere characterized by a hollow tubular body with end members sealing the open ends and apertures through the end members, a porous core member impregnated with a vaporizing composition, having a multiplicity of passages defined through the core member communicating between the end members and having end surfaces displaced from the end members, and a mounting means to maintain the device in a position such that there is free access of the atmosphere through the apertures of both ends. The device provides a continuous dispensing of a vaporizing composition and can provide a greatly increased dosage to the atmosphere as required from time to time. One specific feature of a preferred embodiment of our invention is a pumping means to further aid in rapid dispensing of vapors. A primary application is the deodorizing of a room.

Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
91 words
A device for dispensing a vaporizing composition to the surrounding atmosphere, comprising: a hollow, tubular body having two ends; two end members sealing said ends, each of said end members defining at least one aperture therethrough; a core member within said body impregnated with said vaporizing composition, said core member defining a multiplicity of passages communicating between said end members and having end surfaces displaced from said end members; and mounting means for said body member maintaining free access of the atmosphere through the apertures of both of said end members.
Claim 2
Independent Claim
91 words
A device for dispensing a vaporizing composition to the surrounding atmosphere, comprising: a hollow, tubular body having two ends; two end members sealing said ends, each of said end members defining at least one aperture therethrough; a core member within said body impregnated with said vaporizing composition, said core member defining a multiplicity of passages communicating between said end members and having end surfaces displaced from said end members; and mounting means for said body member maintaining free access of the atmosphere through the apertures of both of said end members.
Claim 3
Dependent Claim
12 words
The device of claim 1 wherein said body is of cylindrical configuration.
Claim 4
Dependent Claim
17 words
The device of claim 2 wherein said core member comprises convoluted corrugated cardboard concentric with said body.
Claim 5
Dependent Claim
30 words
The device of claim 3 wherein at least one of said end members has a substantially flat portion normal to the axis of said body, said portion defining said apertures.
Claim 6
Dependent Claim
25 words
The device of claim 4 wherein said core member has at least one end slant cut with respect to said axis and said flat portion.
Claim 7
Dependent Claim
21 words
The device of claim 3 wherein said displacement is achieved by spacing means between said end members and said core members.
Claim 8
Dependent Claim
19 words
The device of claim 2 wherein said mounting means comprises a pedestal connected to one of said end members.
Claim 9
Dependent Claim
38 words
The device of claim 2 wherein at least one of said end members is slidably sealed to said body and has apertures positioned to be adjustably closed by relative axial movement of said end member and said body.
Claim 10
Dependent Claim
12 words
The device of claim 1 further including means to seal said apertures.
Claim 11
Dependent Claim
22 words
The device of claim 1 further including movable means associated with said tubular body to pump vaporized composition from within said body.
Claim 12
Dependent Claim
53 words
The device of claim 10 wherein said pump means comprises said core member being of dimensions with respect to said tubular body such that void space is defined completely therearound when said core member is in a central position in said body, thereby allowing free movement of said core member within said body.
Claim 13
Dependent Claim
16 words
The device of claim 10 wherein said body is of substantially uniform cross-section along an axis.
Claim 14
Dependent Claim
39 words
The device of claim 12 wherein said tubular body comprises inner and outer telescoping members in substantially air-tight slidable contact, each of said telescoping members having an extreme and a medial end, said end members sealing said extreme ends.
Claim 15
Dependent Claim
26 words
The device of claim 13 wherein said inner telescoping member has a third end member sealing its medial end, said third end member defining apertures therethrough.
Claim 16
Dependent Claim
17 words
The device of claim 14 wherein said inner telescoping member is longer than said outer telescoping member.
Claim 17
Dependent Claim
38 words
The device of claim 13 wherein said apertures in said end member attached to said outer telescopinG member are located in a position such that they can be adjustably closed by relative axial movement of said telescoping members.
Claim 18
Dependent Claim
17 words
The device of claim 13 wherein said core member comprises convoluted corrugated cardboard concentric with said body.
Claim 19
Dependent Claim
37 words
The device of claim 17 wherein at least one of said end members attached to said inner telescoping member has a substantially flat portion normal to the axis of said body, said portion defining said apertures therein.
Claim 20
Dependent Claim
25 words
The device of claim 18 wherein said core member has at least one end slant cut with respect to said axis and said flat portion.
Claim 21
Dependent Claim
21 words
The device of claim 17 wherein said displacement is achieved by spacing means between said end members and said core members.
Claim 22
Dependent Claim
19 words
The device of claim 13 wherein said mounting means comprises a pedestal attached to one of said extreme ends.
Claim 23
Dependent Claim
12 words
The device of claim 13 further including means to seal said apertures.
Claim 24
Independent Claim
