Abstract

Abstract A stackable safety ash tray having a flattened dish-shaped body with an upwardly extending sidewall around the outer edge. An elevated barrier having integrally formed cigarette snuffing devices is arranged across the ash tray body and is attached to the sidewall at a location below the upper edge of the sidewall. The snuffing devices are positioned in a generally vertical arrangement with stepped internal bores for insertion and extinguishing a lighted cigarette. The undersurface of the body is formed with recesses which conform to the upper surface of an identical ash tray whereby a plurality of the ash trays may be positioned in a stacked arrangement. When stacked, the cavity of each of the lower ash trays is sealed so that any burning material contained therein will be extinguished.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 405 words
A stackable safety ashtray comprisiNg: a. a generally dish-shaped body means having a substantially flat base means and upwardly extending side wall arranged continuously around the outer perimeter of said base means so as to form an open interior cavity within said body means, the outer surface of said sidewall being arranged generally perpendicular to said base means, said sidewall having parallel upper and lower edges and the upper edges of said sidewall lying in a plane which is generally parallel to said base means, b. a barrier means disposed across the interior cavity of said body means and attached to the inside surface of said sidewalls, the intermediate portion of said barrier means being arranged to extend above the upper edges of said sidewalls and including cigarette holding means for resting a lighted cigarette so that both ends are positioned over the interior cavity of said body means to prevent the cigarette from falling outside of the sidewalls of the ashtray, the end portions of the barrier means being sloped downwardly so that the upper surface of said barrier means intersects the sidewall at a point which is substantially below the upper edge of said sidewall to prevent a lighted cigarette from being positioned between the barrier means and said sidewalls, c. at least one cigarette snuffing means attached to the side of the intermediate portion of said barrier means and arranged for extinguishing a lighted cigarette which is merely inserted therein, and d. recessed means formed in the undersurface of said body means to permit similar ashtrays to be stacked, said recess means including means providing a recessed cavity formed in the bottom surface of said base means and a recessed notch formed around the perimeter of the lower edge of said sidewalls, said recessed cavity means being separated from said recessed notch means, said recessed cavity means being shaped to receive the upper intermediate portion of the barrier means of a similar ashtray, said recessed notch being sized to fit the upper edge of the sidewall of a similar ashtray whereby a plurality of ashtrays can be stacked with the edges of the sidewalls telescoped to form a seal around the upper edge of the body means of the lower ashtrays so that the interior cavity of each of the lower stacked ashtrays is substantially sealed to exclude air and extinguish any burning materials that may be present in the interior cavities.

A stackable safety ashtray comprisiNg: a. a generally dish-shaped body means having a substantially flat base means and upwardly extending side wall arranged continuously around the outer perimeter of said base means so as to form an open interior cavity within said body means, the outer surface of said sidewall being arranged generally perpendicular to said base means, said sidewall having parallel upper and lower edges and the upper edges of said sidewall lying in a plane which is generally parallel to said base means, b. a barrier means disposed across the interior cavity of said body means and attached to the inside surface of said sidewalls, the intermediate portion of said barrier means being arranged to extend above the upper edges of said sidewalls and including cigarette holding means for resting a lighted cigarette so that both ends are positioned over the interior cavity of said body means to prevent the cigarette from falling outside of the sidewalls of the ashtray, the end portions of the barrier means being sloped downwardly so that the upper surface of said barrier means intersects the sidewall at a point which is substantially below the upper edge of said sidewall to prevent a lighted cigarette from being positioned between the barrier means and said sidewalls, c. at least one cigarette snuffing means attached to the side of the intermediate portion of said barrier means and arranged for extinguishing a lighted cigarette which is merely inserted therein, and d. recessed means formed in the undersurface of said body means to permit similar ashtrays to be stacked, said recess means including means providing a recessed cavity formed in the bottom surface of said base means and a recessed notch formed around the perimeter of the lower edge of said sidewalls, said recessed cavity means being separated from said recessed notch means, said recessed cavity means being shaped to receive the upper intermediate portion of the barrier means of a similar ashtray, said recessed notch being sized to fit the upper edge of the sidewall of a similar ashtray whereby a plurality of ashtrays can be stacked with the edges of the sidewalls telescoped to form a seal around the upper edge of the body means of the lower ashtrays so that the interior cavity of each of the lower stacked ashtrays is substantially sealed to exclude air and extinguish any burning materials that may be present in the interior cavities.
Claim 3
Dependent Claim 36 words
An ashtray as defined in claim 1 wherein: the barrier cigarette holding means includes means providing at least one semi-circular recess in the upper edge of said barrier means for holding the barrel of a cigarette.
Claim 4
Dependent Claim 130 words
An ashtray as defined in claim 1 wherein: said snuffing means includes means providing a generally vertical stepped open bore having a bevelled upper end for guiding the insertion of the lighted cigarette and having a lower open end slanted at an angle with the longitudinal axis of said bore means to prevent clogging by cigarette debris, the upper portion of the stepped bore means having a diameter sized for free insertion of said cigarette and the lower portion of said bore means being coaxial with the upper portion and having a smaller diameter sized to prevent the cigarette from passing therethrough, the intersection between said bores means forming a step which supports said cigarette so that it is held in a position which will cause it to be extinguished.
