Abstract
A windproof ashtray. A hollow, aerodynamically configured ashtray structure is provided with a plurality of generally upstanding, circumferentially spaced cigarette-receiving bores, some of which protect a burning cigarette inserted therein from extinguishment while holding it securely against the wind and others of which hold the cigarette securely but which extinguish it. The bores which hold but extinguish cigarettes inserted therein terminate at the oxygen-blocking inside bottom wall of the tray whereas the bores which do not extinguish cigarettes inserted therein terminate in a metal insert member that spaces the burning tip of the cigarette away from any oxygen-blocking surface.
Claims20
A windproof ashtray, comprising:
- a hollow housing member;
- a cavity the outer boundaries of which are defined by said housing member;
- said cavity defining an oxygen-containing, substantially dead air space where air currents are minimal;
- a first aperture member formed in a top wall of said hollow housing member;
- a cigarette-supporting base member positioned at a preselected location within said cavity, said preselected location being in substantial alignment with said first aperture member;
- said base member being small in configuration relative to the diameter of a cigarette so that only a small portion thereof supportingly abuts the burning end of a cigarette supported thereby;
- whereby the burning end of a cigarette inserted into said cavity through said first aperture member is supported by said base member and is provided with sufficient oxygen to enable it to continue burning and is protected from extinguishment by wind in the environment external to said housing.
4 more elements
A windproof ashtray, comprising:
- a hollow housing member having an oxygenated interior cavity;
- a first plurality of circumferentially spaced aperture members formed in a top wall of said housing member;
- a plurality of insert members, each insert member being adapted to be inserted into a hollow cavity defined by said housing member and being adapted to engage its associated aperture member;
- each of said insert members having a rim-engaging means that engages the rim of its associated aperture member, a cigarette-supporting base member, and an interconnecting member that interconnects said rim-engaging means and said base member;
- said respective base members having a small dimension relative to the transverse dimension of a cigarette;
- each interconnecting member having a linear configuration so that each base member is substantially aligned with its associated aperture member;
- each interconnecting member having a preselected length that positions said base member upwardly of an interior bottom wall of said housing member;
- whereby the burning end of a cigarette inserted into a first aperture member will be supported by said base member in spaced relation to an interior bottom wall of said housing member so that a smoldering fire burning in said cigarette burning end will continue burning in the oxygenated environment within said housing.
5 more elements
A windproof ashtray, comprising:
- a hollow housing member having a circular planform and an elliptical elevational form;
- a central aperture member formed in a top wall of said housing member;
- a dome-shaped member formed in a bottom wall of said housing member, centrally thereof, projecting upwardly therefrom, and having its apex positioned substantially coincident with a plane defined by said top wall member of said housing member so that said apex does not extend through said central aperture member;
- said dome-shaped member having its axis of symmetry coincident with the center of said central aperture member;
- a first plurality of circumferentially spaced aperture members formed in said top wall of said housing member;
- a plurality of insert members positioned in engaging relation to their associated aperture members;
- each of said insert members operative to supportingly engage the burning end of a cigarette inserted into its associated aperture member without extinguishing the same;
- whereby said central aperture member admits oxygen into the hollow interior of said housing member;
- and whereby said dome-shaped member provides a surface against which burning cigarettes can be extinguished and further provides a barrier means so that air currents external to said housing member are substantially barred from causing air currents within said housing member.
