Abstract

Abstract A dispenser for solid air treating materials having a base container for the material and a displaceable cover. The base contains a socket which is adapted to receive prongs which project from the underside of the cover and to engage the prongs so as to permit the positioning of the cover in different vertically spaced positions with respect to the container and thereby to effect a corresponding release of air treating material.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 137 words
A dispenser for solid volatile materials comprising a container for said volatile material having a socket therein, said socket having two opposing walls terminating in inwardly extending sections; and a cover for said container having at least two resilient prongs extending therefrom insertable and engagingly receivable in the socket of said container, the outer surface of each of said prongs having a first detent means and at least one second detent means positioned at a greater distance from said cover than said first detent means, the positive engagement of said first detent means and said inwardly extending sections effecting the closure of the cover on said container and the positive engagement of said at least one second detent means and said inwardly extending sections resulting in the elevated positioning of said cover with respect to said container.
Claim 2
Dependent Claim 137 words
A dispenser for solid volatile materials comprising a container for said volatile material having a socket therein, said socket having two opposing walls terminating in inwardly extending sections; and a cover for said container having at least two resilient prongs extending therefrom insertable and engagingly receivable in the socket of said container, the outer surface of each of said prongs having a first detent means and at least one second detent means positioned at a greater distance from said cover than said first detent means, the positive engagement of said first detent means and said inwardly extending sections effecting the closure of the cover on said container and the positive engagement of said at least one second detent means and said inwardly extending sections resulting in the elevated positioning of said cover with respect to said container.
Claim 3
Dependent Claim 24 words
The dispenser of claim 1, wherein a section of each of said prongs below said at least one second detent means is tapered downward.
Claim 4
Dependent Claim 36 words
The dispenser of claim 1, wherein the surface of each of said prongs between said first detent means and said at least one second detent means is raised to facilitate release and compression of said prongs.
Claim 5
Dependent Claim 25 words
The dispenser of claim 1, wherein at least one end of said container has supporting means for supporting said dispenser in a vertical upright position.
Claim 6
Dependent Claim 52 words
The dispenser of claim 1, wherein said socket has an upwardly extending outer wall and said cover has a channel surrounding said prongs, the extended wall and the channel being positioned relative to one another such that they are sealingly engaged when said cover is in a closed position on said container.
Claim 7
Dependent Claim 27 words
A multi-unit dispenser for solid volatile materials comprising at least two dispensers according to claim 1 joined along their length by at least one frangible linking means.
Claim 8
Dependent Claim 60 words
The dispenser of claim 1, wherein means are positioned in said socket intermediate and parallel to said inwardly extending sections for limiting the inward resilient movement of said prongs such that when said prongs are in closest permissible proximity to one another, said at least one second detent means cannot readily pass, in an upward direction, said inwardly extending sections.
Claim 9
Dependent Claim 169 words
A dispenser for solid volatile materials comprising a container for said volatile material having support means on one end thereof to support said dispenser in an upright position and a socket centrally located therein having two opposing walls which terminate in inwardly extending sections; and a cover for said container having two resilient prongs extending therefrom, the outer surface of each of said prongs having a first detent means and a second detent means positioned at a greater distance from said cover than said first detent means, the section of each of said prongs below said second detent means being tapered downwards while the surface of each of said prongs between said first and said second detent means being raised; the positive engagement of said first detent means and said inwardly extending sections effecting the closure of the cover on said container and the positive engagement of said second detent means and said inwardly extending sections resulting in the elevated positioning of said cover with respect to said container.
Claim 10
Dependent Claim 169 words
A dispenser for solid volatile materials comprising a container for said volatile material having support means on one end thereof to support said dispenser in an upright position and a socket centrally located therein having two opposing walls which terminate in inwardly extending sections; and a cover for said container having two resilient prongs extending therefrom, the outer surface of each of said prongs having a first detent means and a second detent means positioned at a greater distance from said cover than said first detent means, the section of each of said prongs below said second detent means being tapered downwards while the surface of each of said prongs between said first and said second detent means being raised; the positive engagement of said first detent means and said inwardly extending sections effecting the closure of the cover on said container and the positive engagement of said second detent means and said inwardly extending sections resulting in the elevated positioning of said cover with respect to said container.
Claim 11
Dependent Claim 27 words
A multi-unit dispenser for solid volatile materials comprising at least two dispensers according to claim 8 joined along their length by at least one frangible linking means.
Claim 12
Dependent Claim 60 words
The dispenser of claim 8, wherein means are positioned in said socket intermediate and parallel to said inwardly extending sections for limiting the inward resilient movement of said prongs such that when said prongs are in closest permissible proximity to one another, said at least one second detent means cannot readily pass, in an upward direction, said inwardly extending sections.
Claim 13
Dependent Claim 27 words
A multi-unit dispenser for solid volatile materials comprising at least two dispensers according to claim 10 joined along their length by at least one frangible linking means.
