BACKGROUND OF THE INVENTION
This invention relates generally to a receptacle for receiving and disposing of combustible articles. Particularly, this invention relates to a cigarette disposal assembly for the disposal of combustible articles such as cigarettes and the like. The disposal assembly of the invention provides an efficient means to dispose of cigarette butts, matches and the like, especially in outdoor smoking areas.
With more and more restrictions placed on public smoking, the most popular and frequently used areas to engage in smoking are now outdoors. The cigarette disposal assembly of this invention makes the maintenance of these smoking areas easy to maintain while improving the appearance of the outdoor areas designated for smoking. The cigarette disposal assembly is an economical and user friendly device that provides easy use and maintenance.
The cigarette disposal assembly may be placed in outdoor smoking areas to give employees and other smokers a sanitary disposal unit, for example. The cigarette disposal assembly may also be placed at entrances of business establishments to keep sidewalk and entrance landscapes orderly and clean.
SUMMARY OF THE INVENTION
The cigarette disposal assembly of the invention comprises a base structure and a cooperating removable top member. A centrally disposed inlet chute structure having a flared inlet and a downwardly extending conduit is positioned in the removable top member and extends into the base structure. A seal structure may be incorporated into the bottom of the top member. The seal structure is adapted to secure the inlet chute structure to the top member and to seal the removable top member to the base structure.
The inlet chute is constructed and arranged to accept combustible articles, such as cigarettes, without allowing other trash to accumulate inside the disposal assembly. Due to the constriction of the conduit portion, oxygen is limited and cigarette butts and the like are thereby extinguished and concealed to keep the surrounding property clean. The base structure preferably has a large capacity so that a large quantity of extinguished articles, i.e., thousands of cigarette butts, may be stored to thereby reduce maintenance requirements. When full, the top member may be removed and the base structure may be emptied in a manner similar to emptying a wastebasket. A steel or aluminum liner or the like may be attached or placed within the base structure, thereby eliminating the dirty job of separating the liner or container from the inside of the base structure or housing. An added weight, i.e., a quantity of sand, is provided in the base structure to make the cigarette disposal assembly stable in high traffic or windy areas.
The components of the cigarette disposal assembly, i.e., base structure, top member and seal structure, are preferably roto-molded using a polymeric resin, resistant to cracking, peeling and which provides an assembly that does not rust. A security locking system comprising a cable and lock may be provided to secure the removable top member to the base structure and to secure the cigarette disposal assembly to a fixed object to protect against vandalism and/or theft.
The disposal assembly is constructed and arranged so that emptying the disposal assembly is a clean and simple operation. The top member may be unlocked and twisted from the base structure. The entire base structure may be dumped like a waste basket. In summary, the cigarette disposal assembly is an attractive, economical and low maintenance alternative to open top ashtrays.
These and other benefits of this invention will become clear from the following description by reference to the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1 and 7, the cigarette disposal assembly 10 of the invention is shown comprised of a cylindrical base member 11 having a flared bottom portion 16. A removable top member 12 is shown mounted to the top of the base member 11. An inlet structure 13 having a flared inlet 14 is shown extending upward from the top member 12. The flared inlet 14 is preferably constructed of metal to receive combustible articles such as cigarette or cigar butts, matches, etc. A logo 20, an encircled lit cigarette, preferably in color, is shown disposed on the side of the cylindrical base member 11 to alert smokers that the disposal or receptacle assembly 10 is constructed for receiving smoking materials and combustible articles. The logo or signage 20, showing a lit cigarette, may be applied to or molded into the body of the base member 11. The base member is preferably constructed of roto-molded granite speckled color design or the like.
Referring further to FIGS. 3 and 7, the removable top member 12 is shown to have a handle member 17 extending upwardly therefrom and which may be used to grip, lock and move the assembly 10. Peripheral locking members 19 are shown extending peripherally outward from the top member 12 and which cooperate with outwardly extending pegs 18 at the top of the base member 11, as particularly shown in FIG. 3. The opposing pegs or tabs 18 are adapted to receive the peripheral locking members 19 of top member 12. The top member 12 may be removed or attached to the base member 11 by a ¼ turn or revolution of the top member 12 with respect to the base member 11. As shown particularly in FIGS. 2 and 7, the handle member 19 has an aperture 32 through which the shackle of the padlock structure 23 is secured. The loop 30 of the securement cable 22 is also shown attached to the lock structure 23.
Referring to FIGS. 5 and 6, the inlet structure 13 is shown comprised of a flared upper portion 14 and a downwardly extending conduit 25. The inlet structure 13 is preferably constructed of a non-combustible material, such as metal or the like. A combustible article such as a lit cigarette or match is extinguished on the flared upper portion 14. The extinguished cigarette butt falls through the conduit 25 and into a container 15 constructed of a non-combustible material, i.e., metal or the like, which is shown positioned adjacent the bottom of the base member 11. At the flared bottom 16 of the base member 11 a quantity of sand or like weighted material is preferably placed to provide stability for the assembly 10. Space 26 above the sand 21 allows the sand to flow and settle within the flared base bottom 16. The container 15 is preferably tightly fitted within the base member 11, for example, via a frictional fit or by fastening means. A non-combustible liner 27, i.e., metal, aluminum or the like, or other non-combustible structure is shown positioned within and adjacent the interior wall of the base member 11. Alternatively, the base member 11 may be constructed of a thermoset crosslinked polymer, i.e., crosslinked P.E., which would eliminate the requirement for the bucket member 15 or similar container or a metal liner within the base member. In the latter cases, however, means, such as a non-combustible plate, may be provided within the base to secure the sand or similar weighted material in the bottom of the base member 11.
Referring to FIG. 6, the inlet structure 13 is shown secured to the top member 12 by means of a seal structure 28 and a securement structure 29. The seal structure 28 is shown disposed in touching relationship with the inside of the top member 12. The seal structure 28 is preferably a circular member having a downwardly extending peripheral lip 31. As shown, when the top member 12 is secured to the top of the base structure 11, the side wall of the structure 11 is disposed between the top member 12 and the peripheral lip 31 of the seal structure 28. Further, the top of the liner 27 is shown in abutment with the peripheral lip 31. In this manner, the top member 12 may be secured in sealing engagement with the base structure 11 to thereby minimize the entry of air into the disposal assembly 10 and to minimize the exit of ashes and soot from the interior of base structure 11.
FIG. 6 further shows the inlet structure 13 secured to the top member 12 and the seal structure 28 by means of a securement structure 29. The securement structure 29 may be a slot cut out from the conduit 25 and which is bent into a horizontal position to secure inlet structure 13 and to provide a unitary structure comprising the top member 12, inlet structure 13 and seal structure 28.
Referring to FIGS. 2, 8 and 9, a securement cable 22, i.e., a 0.25 inch diameter steel cable approximately 5 feet long, padlock structure 23 and key structure 24 combination may be used to secure the top member 12 to the base member 11 as well as the assembly 10 to a secure object, i.e., a bench or building component. Apertures in the handle member(s) 19 may be provided for the utilization of the securement cable 22 and the padlock 23, respectively.
In use, combustible articles such as cigarette butts, for example, are put out on the flared inlet 14 of the inlet structure 13 and dropped down through conduit 25 into the container 15. The lack of oxygen supply in the base structure 11, prevents combustion and the size or diameter of the conduit 25 limits the material that can enter base structure 11. As shown in FIGS. 3 and 4, to empty the disposal assembly 10, the top member 12 is removed from base structure 11 and turned upside down to discard the cigarette butt contents.
An exemplary disposal assembly 10, as shown in FIG. 5, has a flared inlet 14 and conduit structure 25 of approximately 2 inches in length to prevent clogging, a base structure 11 having a height “b” of approximately 25 inches, a diameter “b” of approximately 7 inches and a flared base bottom 16 having a diameter “c” of approximately 9 inches. The seal structure 28, as shown in FIG. 6, would have a diameter of approximately 6 inches in this assembly 10 configuration. The seal structure 28 is constructed of a ¼ inch thick molded non-combustible material, i.e., crosslinked thermoset polyethylene. The container 15 may be a #10 metal container (one gallon content) which is affixed to the interior of the base member 11. The amount of sand 21 in the base member 11 of the cigarette disposal assembly 10 having these dimensions is approximately five pounds.
As many changes are possible to the embodiments of this invention, utilizing the teachings thereof, the description above and the accompanying drawings should be interpreted in the illustrative and not the limited sense.
