Abstract
Abstract A vapor releasing device for reodorants, pesticides or other vaporous materials is defined by a flat upper portion having opposing downwardly extending walls which contain inwardly protruding lips forming slots or openings. A flexible solid containing the vaporous material is engaged in the slot or openings. Extending downwardly from the upper portion at each end of the slot or opening is a post which prevents removal or fallout of the flexible solid when engaged.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
89 words
A vapor releasing device comprising a flat upper portion having opposing downwardly extending walls; said walls containing inwardly protruding lips running longitudinally along said walls thereby forming an open-ended slot; said upper portion having downwardly extending posts at each end of said slot and at right angles to said downwardly extending walls; said slot holding a flexible solid containing a vapor releasing material which flexible solid supportingly rests on said inwardly protruding lips and is held in place by engagement with the flat upper portion and downwardly extending posts.
Claim 2
Dependent Claim
89 words
A vapor releasing device comprising a flat upper portion having opposing downwardly extending walls; said walls containing inwardly protruding lips running longitudinally along said walls thereby forming an open-ended slot; said upper portion having downwardly extending posts at each end of said slot and at right angles to said downwardly extending walls; said slot holding a flexible solid containing a vapor releasing material which flexible solid supportingly rests on said inwardly protruding lips and is held in place by engagement with the flat upper portion and downwardly extending posts.
Claim 3
Dependent Claim
21 words
A vapor releasing device according to claim 1 wherein said device has means for attaching said device to a supporting surface.
Claim 4
Dependent Claim
16 words
A vapor releasing device according to claim 1 wherein the flexible solid is a thermoplastic resin.
Claim 5
Dependent Claim
16 words

Dependent Claim
16 words
A vapor releasing device according to claim 4 wherein the vapor releasing material is a reodorant.
Claim 7
Dependent Claim
32 words
A vapor releasing device according to claim 5 wherein the thermoplastic resin is in two pieces, the dividing line between said pieces being in a plane perpendicular to said inwardly protruding lips.
Claim 8
Dependent Claim
33 words
A vapor releasing device according to claim 6 wherein one thermoplastic resin contains a pesticide as the vapor releasing material and the second thermoplastic resin contains a reodorant as the vapor releasing material.
Claim 9
Dependent Claim
16 words

Claim 11
Dependent Claim
142 words
A pesticide vapor releasing device suitable for use in garbage cans comprising a flat upper portion having means for attaching said device to the inside of a garbage can and having downwardly extending walls containing inwardly protruding lips running longitudinally along the walls thereby forming a slot which is open at least at one end, said flat upper portion having a downwardly extending post at the open end of the slot and at right angles to the downwardly extending walls, said slot holding a flexible solid thermoplastic resin containing a vaporizable pesticide which supportingly rests on the inwardly protruding lips and is held in place by engagement with the flat upper portion and downwardly extending post, the bottom surface of the solid flexible thermoplastic resin being substantially exposed to air circulation thereby releasing pesticide vapors to the inside of the garbage can.
