Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
134 words
A space deodorizer composed essentially of sintered powdered aluminum adapted to hold a controllably entrained normally volatile liquid space deodorizer which comprises a shaped sintered aluminum powder compact substantially impervious to the passage therethrough of the deodorizer, the shaped compact having a top platform portion and a peripheral sidewall portion extending downwardly from the platform portion to define an interior recessed portion below the top platform portion, a porous mass of sintered aluminum powder in fixed sintered weld contact with the interior recessed portion of the shaped compact capable of being impregnated with a supply of said deodorant, the sidewall portion of the shaped compact being provided with at least one laterally positioned opening communicating with the porous sintered mass which permits escape to the ambient atmosphere of deodorant volatilized from said supply thereof.
Claim 2
Dependent Claim
134 words
A space deodorizer composed essentially of sintered powdered aluminum adapted to hold a controllably entrained normally volatile liquid space deodorizer which comprises a shaped sintered aluminum powder compact substantially impervious to the passage therethrough of the deodorizer, the shaped compact having a top platform portion and a peripheral sidewall portion extending downwardly from the platform portion to define an interior recessed portion below the top platform portion, a porous mass of sintered aluminum powder in fixed sintered weld contact with the interior recessed portion of the shaped compact capable of being impregnated with a supply of said deodorant, the sidewall portion of the shaped compact being provided with at least one laterally positioned opening communicating with the porous sintered mass which permits escape to the ambient atmosphere of deodorant volatilized from said supply thereof.
Claim 3
Dependent Claim
49 words
A space deodorizer according to claim 1 in which the sides of the interior recessed portion are defined by a retaining wall integrally formed with the impervious compact and extending downwardly from the underside of the top platform portion and spaced inwardly from the sidewall portion of the compact.
Claim 4
Dependent Claim
26 words
A space deodorizer according to claim 1 in which a moisture-impervious barrier is secured across the lower edge of the peripheral sidewall portion of the compact.
Claim 5
Dependent Claim
25 words
A space deodorizer according to claim 2 in which a moisture-impervious barrier is secured across the lower edge of the retaining wall of the compact.
