Abstract
Abstract A thermal sensitive deodorant wafer is disclosed which is used to neutralize odors caused by subjecting certain materials to elevated temperatures. A pad (2) is impregnated with a heat releasable deodorant and is encapsulated in a thermal sensitive shell (4) to form a wafer-like element (6). The shell decomposes when subjected to the elevated temperatures whereupon the deodorant is released to neutralize the odors.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
92 words
A thermal sensitive deodorant wafer, comprising: a thermal sensitive thin walled shell; a pad impregnated with a heat releasable deodorant encapsulted within the shell, with the shell and the pad encapsulated therein providing the thermal sensitive deodorant wafer; the shell of the wafer being of a material sensitive to elevated temperatures for decomposing and exposing the pad when subjected to said temperatures; and the deodorant on the exposed pad being of a composition responsive to the elevated temperatures for being released from the pad and thereupon being effective for neutralizing offensive odors.
Claim 2
Dependent Claim
92 words
A thermal sensitive deodorant wafer, comprising: a thermal sensitive thin walled shell; a pad impregnated with a heat releasable deodorant encapsulted within the shell, with the shell and the pad encapsulated therein providing the thermal sensitive deodorant wafer; the shell of the wafer being of a material sensitive to elevated temperatures for decomposing and exposing the pad when subjected to said temperatures; and the deodorant on the exposed pad being of a composition responsive to the elevated temperatures for being released from the pad and thereupon being effective for neutralizing offensive odors.
Claim 3
Dependent Claim
61 words
A thermal sensitive deodorant wafer as described by claim 1, wherein: the pad is of a relatively absorbent material; and the deodorant with which the pad is impregnated is an essential oil deodorant which vaporizes when the exposed pad is subjected to the elevated temperatures so as to be released from the pad and thereupon being effective for neutralizing offensive odors.
Claim 4
Dependent Claim
123 words
A thermal sensitive deodorant wafer for neutralizing offensive odors caused by subjecting certain substances to elevated temperatures, comprising: a relatively absorbent pad impregnated with an essential oil deodorant; a thin walled shell of a thermal sensitive material encapsulating the impregnated pad and forming therewith the thermal sensitive deodorant wafer; the thin walled shell being of a material sensitive to the elevated temperatures to which the certain substances are subjected so as to decompose when subjected to said temperatures, and to thereupon expose the pad encapsulated therein; and the essential oil deodorant with which the exposed pad is impregnated being of a composition responsive to the elevated temperatures for vaporizing so as to be released from the pad and thereupon neutralizing the offensive odors.
Claim 5
Dependent Claim
123 words
A thermal sensitive deodorant wafer for neutralizing offensive odors caused by subjecting certain substances to elevated temperatures, comprising: a relatively absorbent pad impregnated with an essential oil deodorant; a thin walled shell of a thermal sensitive material encapsulating the impregnated pad and forming therewith the thermal sensitive deodorant wafer; the thin walled shell being of a material sensitive to the elevated temperatures to which the certain substances are subjected so as to decompose when subjected to said temperatures, and to thereupon expose the pad encapsulated therein; and the essential oil deodorant with which the exposed pad is impregnated being of a composition responsive to the elevated temperatures for vaporizing so as to be released from the pad and thereupon neutralizing the offensive odors.
