Description
This invention is directed to a cigarette-extinguishing ashtray and more particularly is direc-ted to a cigarette-extinguishing ashtray which is of simple construction, simple to use, and readily cleanable.
BACKGROUND OF THE INVENTION
Cigarette-extinguishing ashtrays have been known for many years. In one common form, holes or bores in the ashtray of a diameter slightly larger than the diameter of a regular cigarette are positioned on the ashtray, usually on the top surface thereof, and the person desiring to extinguish a cigarette simply inserts the lit end of the cigarette into the extinguishing hole, whereupon the cigarette extinguishes itself in a matter of seconds due to the walls of the hole preventing sufficient o~ygen reaching the lit end of the cigarette. An obvious advantage of this type of ashtray is that it avoids the unsightly and generally malodorous practice common with simple dish-type ashtrays of squashing the lit end of the cigarette into the ashtray, which sometimes causes burnt fingertips, burnt fingernails, particularly with women having long fingernails, and unsightly bent cigarette butts which must be removed from the ashtray.
A major disadvantage with the cigarette-extinguishing design of ashtrays available on the market or taught in the literature is that they are generally complicated in construction, difficu]t and complicated to take apart, difficult to clean, and costly because of their complex construction.
The applicant's invention is directed to a cigarette-extinguishing type of ashtray which is of simple construction, of low cost, is simple to use, is dismantleable, and is easy to clean. In its simplest form, the ashtray is constructed of two simple parts which can be snapped together. The cigarette snuffing part can be formed of any suitable fire-resistant, non-combustible material such as glass or metal, but preferably is of a heat and fire-resistant, relatively rigid plastic, such as a -thermosetting phenol-formaldehyde resin. The part underlying the snuffing part can also be formed of any suitable fire-resistant, non-combustible material such as glass or metal, but preferably is formed of a plastic which is fire and heat resistant. The plastic should be slightly elastic so that it can deform slightly when being snapped together with the snuffing part.
The cigarette-extinguishing ashtray 20 comprises:
(a) a top portion having therein at least one snuff-hole of a diameter slightly larger than the diameter of a regular cigarette, and an extinguished cigarette-butt receiving area;
(b) a base portion capable of closing off the bottom of the snuff-hole in the top portion and rotatably at-tached to the top portion (a) so that the base portion can be rotated relative to the top portion;
~s~
(c) at least one hole in the base portion (b) which can be rotated into alignment position at the base of the snuff-hole in the top portion (a) by rotating the base portion relative to the top portion (a);
(d) a groove around the circumference of the base of the snuff-hole of the upper portion adjacent the base portion (b);
and (e) a raised rim around the circumference of the alignment hole in the base portion (b) which rim corresponds in dimension with and fits within the circumferential groove (d) of the top portion when the hole in the base portion (b) is rotated into a posi-tion of alignment with the snuff hole.
An ashtray as described wherein the base portion (b) is attached to the upper portion (a) by means of a rim-groove combination, the rim on one portion and the groove on the other portion, the rim-groove combination enabling the upper portion and the base portion to be ro~ated relative to one another.
An ashtray as described wherein a raised rim with no central opening therein corresponding in dimension and shape with the groove at the base of the snuff-hole of the upper portion (a) is located on -the base portion (b) so that the base portion (b) can be rotated relative to the upper portion (a) to a position wherein the raised rim with the central opening rests ~;3~Z
within the groove at the base of the snuff-hole of the upper portion (a), this position being alternative to the position where the rim (e) rests within groove (d).
An ashtray as described wherein four snuff-holes are located in the top portion (a) and four alignment holes are located in the base portion ~b).
An ashtray as described wherein four grooves are located at the base of the four snuff-holes in the top portion (a) and four raised rims are located around the circumference of the four alignment holes in the base portion (b), and the four grooves align with the respective four raised rims when the base portion (b) is rotated to an appropriate position relative to the top portion (a).
An ashtray as described wherein four stop-rims with no central openings therein are located on the base portion in the areas between each of the four alignment hole rims and the four stop rims can be moved into alignment with -the respective four grooves at the bases of the four snuff-holes by rota-ting the base portion (b) to an appropriate position relative to the top portion (b).
An ashtray as described wherein a cigarette butt receptacle is secured below the base portion (b) of the ashtray, and extinguished cigarettes can be dropped into the receptacle through the snuff-holes when the snuff-holes in the top portion (a) and the alignment holes in the base portion (b) are in a position of alignment.
An ashtray as described wherein the top area 3~
of each snuff-hole is bevelled or rounded. The snuff-holes can be cylindrical or truncated-conical in shape.

Referring to FIGURE 1, which represents a plan view of the ashtray 1, a snuffer-top 2 is mounted on a bottom plate 3. The snuffer-top 2 is constructed in annular ring form and has a hole in the centre thereof.
Located periodically around the body of the annular ring shaped snuffer-top 2 are four snuff-holes 4. Positioned between each snuff-hole 4, and extending radially, are four rest-grooves 5, which can be used for purposes of receiving cigarettes that are still burning and intended for continued use by the cigarette-smoker. The diameter of snuff-holes 4 is slightly larger than the average diameter of a regular cigarette. Thus, snuff-holes 4 can readily receive the lit end of a lighted cigarette.
~.~53~
The tops of the snuff-holes 4 are rounded or bevelled to ease the insertion of the lit ends of the lighted cigarettes into the holes. The holes 4 may be cylindrical or truncated-conical in shape. It will be understood that while FIGURE 4 shows four snuff-holes, and four rest-grooves 5, alternative designs can be visualized having any number of snuff-hoies and any number of rest-grooves.
Referring to FIGURE 2, which represents a section view of the ashtray 1 taken through section line
2-2 of FIGURE 1, it is seen that bottom plate 3 is snapped into the central hole of snuffer-top 2 and held in place against snuffer-top 2 by means of a snap-on groove 6, with a corresponding receiving rim formed in the central hole in snuffer-top 2. This rim, which runs around the circumference of the central hole, fits in groove 6 such that snuffer-top 2 and bottom plate 3 can be rotated relative to one another about a central vertical axis that is common to both bottom plate 3 and snuffer-top 2.
Located at the bottom of snuff-holes 4 are snuff-hole base rim grooves 7. In the position shown in FIGURE 2, bottom plate 3 closes off the bottom of snuff-hole 4. In this position, the snuff-holes of the ashtray can be used for the purpose of extinguishing the lit ends of cigarettes. The extinguished cigarettes may then be discarded in the central area of the ashtray 1.
FIGURE 3, which represents a plan view of the bottom plate 3, has formed therein four equally spaced bottom plate a:Lignment holes 8, which correspond in 6~
position with the four snuff-holes 4 of snuffer-top 2.
A raised alignment hole stop-rim 9 is formed around the circumference of each alignment hole 8. These stop rims 9 are dimensioned to fit within base rim grooves 7.
Positioned spa-tially between each of the four alignment holes 8 and at a constant distance from the central axis are four stop-rims 10. The central areas of stop-rims 10 do not have any hole therethrough, such as is the case with alignment holes 8, and surrounding alignment holes stop-rims 9.
When bottom pla.e 3, as illustrated in FIGURE 3, is snapped in place against snuffer-top 2 by means of rotation groove 6 and the corresponding rim on snuffer-top 2, bottom plate 3 can be rotated relative to snuffer-top 2 such that alignment holes 8 can be brought into alignment with snuff-holes 4 of the snuffer-top 2.
The alignment hole stop-rims 9 "click" into place in respective snuff-hole base rim grooves 7 of each snuff-hole 4, to enable -the user to know readily that each snuff-hole 4 is aligned with each alignment hole 8.
In this configuration, with the holes aligned, the ashtray can be readily cleaned by simply running a brush or some other cleaning object through -the four snuff-holes 4 and the corresponding four alignment holes 8, or washing the ashtray with detergent and water, or washing the ashtray in a dishwasher, or by some other suitable means. When the ashtray is in this configuration, it is also possible to push a cigare-tte completely through any of the four holes in the ashtray, ~L5;3~
first t~lrough snuff-hole 4, and then through alignment hole 8.
When it is desired to have the ashtray 1 in cigarette-extinguishing con:Eiguration, bottom plate 3 is rotated relative to snuffer-top 2 from the position where the snuff-holes 4 and alignment holes 8 align with one another, to the position where the four stop-rims 10 "click" into place in the respective four snuff-hole base rim grooves 7 located at the base of each of the four snuff-holes 4. Since the central areas for each stop-rim 10 are solid, snuff-holes 4 are effectively sealed at the bottom thus enabling the lit end of a lighted cigarette to be easily extinguished in a matter of seconds by inserting the lit end into any one of the four snuff-holes 4 from the top. The extinguished cigarette butt can then be discarded in the central opening.
One simple alternative method of using the ashtray 1 is to extinguish the lit end of a cigarette in a snuff-hole 4, when the stop-rims 10 are in position in the rim grooves 7 at the base of the four snuff-holes 4, and then, once the cigarette is extinguished in a matter of seconds, rotate bottom plate 3 relative to snuffer-top 2, to the position where the alignment holes 8 and rims 9 "click" into position in the respective grooves 7 of the snuffer-holes 4, whereupon the extinguished cigarette can then be dropped through plate 3. When the ashtray is used in this manner, it is helpful to have a cigarette butt receptacle 11, as represented in FIGURE 4, snapped in place immediately under bottom r `~ ~
1~536~
plate 3. Cigarette butt receptacle FIGURE 11 is preferably made of some suitable fire-resistant, non-combustible material such as glass, metal, or a fire and heat-resistant plastic, so that it will readily hold extinguished cigarette butts, and can be parted ~rom bottom plate 3, if required, so that it can be emptied and the parts thoroughly cleaned. Once the extinguished cigarette butt has dropped into the receptacle, then snuffer-top 2 is rotated again relative to bottom plate 3 so that stop-rims 10 are clicked into place in groove 7 at the base of the respective snuff-holes 4.
In this orientation, the ashtray is ready to extinguish further cigarettes.
FIGURE 5 illustrates an alternative embodiment of the ashtray according to the invention. As illustrated in FIGURE 5, bottom plate 12, which can be rotated relative to snuffer-top 13, is rotatably engaged with snuffer-top 13 by means of an upwardly extending circumferentlal lip which can be snapped over rotation rim 14, formed at the base of the exterior circumfer-ential surface of snuffer-top 13. In the orientation shown, the bottom-plate alignment holes 15 align with the snuff-holes 16 of snuffer-top 13. As with the embodiments discussed above in association with FIGURES 1 to 4, the bottom plate 12 can be rotated to close the bottom openings of snuff-holes 16.
One major advantage of the applicant's construction of ashtray in its various embodiments is that it is of very simple construction, comprising in its simplest form only two parts, both of which can be -manufactured of relatively low cost materials, such as glass, metal or plastic. Another advantage is that the ashtray can be cleaned by any one of a number of suitable means in its assembled form or the respective parts can be detached from one another for a thorough cleaning of the separate parts. A further advantage is that if one part of the ashtray becomes damaged, that part can be replaced by detaching the parts of the ashtray and installing a new part. The parts are formed of hygienic washable materials and do not have any complicated recesses, springs, metal-on-metal surfaces which tend to become corroded, or any areas which tend to accumulate ashes and general dirt thereby contribu-ting to the generation of offensive odours. The simple design of the various components of the ashtray reduces construction costs because complicated molds are not required in order to form the components of the ashtray.
Moreover, the ashtray is simple to use because of the existence of the stop-rims located respectively around the circumference of the alignment holes in the bottom plate of the ashtray, and in the solid areas between each of the alignment holes. Thus the user, simply by feeling or listening for a click, and looking into one of the snuffer-holes, can immediately tell which of the two alternative types of rims are in position at the base of the snuff-holes and consequently whether the ashtray can be used for extinguishing the lit end of a cigarette.
As will be apparent -to those skilled in the art in the light of the foregong disclosure, many Z
alterations and modifications are possible in the prac-tice of this invention without departing from the spirit or scope thereof. Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims.
: '.
Located at the bottom of snuff-holes 4 are snuff-hole base rim grooves 7. In the position shown in FIGURE 2, bottom plate 3 closes off the bottom of snuff-hole 4. In this position, the snuff-holes of the ashtray can be used for the purpose of extinguishing the lit ends of cigarettes. The extinguished cigarettes may then be discarded in the central area of the ashtray 1.
FIGURE 3, which represents a plan view of the bottom plate 3, has formed therein four equally spaced bottom plate a:Lignment holes 8, which correspond in 6~
position with the four snuff-holes 4 of snuffer-top 2.
A raised alignment hole stop-rim 9 is formed around the circumference of each alignment hole 8. These stop rims 9 are dimensioned to fit within base rim grooves 7.
Positioned spa-tially between each of the four alignment holes 8 and at a constant distance from the central axis are four stop-rims 10. The central areas of stop-rims 10 do not have any hole therethrough, such as is the case with alignment holes 8, and surrounding alignment holes stop-rims 9.
When bottom pla.e 3, as illustrated in FIGURE 3, is snapped in place against snuffer-top 2 by means of rotation groove 6 and the corresponding rim on snuffer-top 2, bottom plate 3 can be rotated relative to snuffer-top 2 such that alignment holes 8 can be brought into alignment with snuff-holes 4 of the snuffer-top 2.
The alignment hole stop-rims 9 "click" into place in respective snuff-hole base rim grooves 7 of each snuff-hole 4, to enable -the user to know readily that each snuff-hole 4 is aligned with each alignment hole 8.
In this configuration, with the holes aligned, the ashtray can be readily cleaned by simply running a brush or some other cleaning object through -the four snuff-holes 4 and the corresponding four alignment holes 8, or washing the ashtray with detergent and water, or washing the ashtray in a dishwasher, or by some other suitable means. When the ashtray is in this configuration, it is also possible to push a cigare-tte completely through any of the four holes in the ashtray, ~L5;3~
first t~lrough snuff-hole 4, and then through alignment hole 8.
When it is desired to have the ashtray 1 in cigarette-extinguishing con:Eiguration, bottom plate 3 is rotated relative to snuffer-top 2 from the position where the snuff-holes 4 and alignment holes 8 align with one another, to the position where the four stop-rims 10 "click" into place in the respective four snuff-hole base rim grooves 7 located at the base of each of the four snuff-holes 4. Since the central areas for each stop-rim 10 are solid, snuff-holes 4 are effectively sealed at the bottom thus enabling the lit end of a lighted cigarette to be easily extinguished in a matter of seconds by inserting the lit end into any one of the four snuff-holes 4 from the top. The extinguished cigarette butt can then be discarded in the central opening.
One simple alternative method of using the ashtray 1 is to extinguish the lit end of a cigarette in a snuff-hole 4, when the stop-rims 10 are in position in the rim grooves 7 at the base of the four snuff-holes 4, and then, once the cigarette is extinguished in a matter of seconds, rotate bottom plate 3 relative to snuffer-top 2, to the position where the alignment holes 8 and rims 9 "click" into position in the respective grooves 7 of the snuffer-holes 4, whereupon the extinguished cigarette can then be dropped through plate 3. When the ashtray is used in this manner, it is helpful to have a cigarette butt receptacle 11, as represented in FIGURE 4, snapped in place immediately under bottom r `~ ~
1~536~
plate 3. Cigarette butt receptacle FIGURE 11 is preferably made of some suitable fire-resistant, non-combustible material such as glass, metal, or a fire and heat-resistant plastic, so that it will readily hold extinguished cigarette butts, and can be parted ~rom bottom plate 3, if required, so that it can be emptied and the parts thoroughly cleaned. Once the extinguished cigarette butt has dropped into the receptacle, then snuffer-top 2 is rotated again relative to bottom plate 3 so that stop-rims 10 are clicked into place in groove 7 at the base of the respective snuff-holes 4.
In this orientation, the ashtray is ready to extinguish further cigarettes.
FIGURE 5 illustrates an alternative embodiment of the ashtray according to the invention. As illustrated in FIGURE 5, bottom plate 12, which can be rotated relative to snuffer-top 13, is rotatably engaged with snuffer-top 13 by means of an upwardly extending circumferentlal lip which can be snapped over rotation rim 14, formed at the base of the exterior circumfer-ential surface of snuffer-top 13. In the orientation shown, the bottom-plate alignment holes 15 align with the snuff-holes 16 of snuffer-top 13. As with the embodiments discussed above in association with FIGURES 1 to 4, the bottom plate 12 can be rotated to close the bottom openings of snuff-holes 16.
One major advantage of the applicant's construction of ashtray in its various embodiments is that it is of very simple construction, comprising in its simplest form only two parts, both of which can be -manufactured of relatively low cost materials, such as glass, metal or plastic. Another advantage is that the ashtray can be cleaned by any one of a number of suitable means in its assembled form or the respective parts can be detached from one another for a thorough cleaning of the separate parts. A further advantage is that if one part of the ashtray becomes damaged, that part can be replaced by detaching the parts of the ashtray and installing a new part. The parts are formed of hygienic washable materials and do not have any complicated recesses, springs, metal-on-metal surfaces which tend to become corroded, or any areas which tend to accumulate ashes and general dirt thereby contribu-ting to the generation of offensive odours. The simple design of the various components of the ashtray reduces construction costs because complicated molds are not required in order to form the components of the ashtray.
Moreover, the ashtray is simple to use because of the existence of the stop-rims located respectively around the circumference of the alignment holes in the bottom plate of the ashtray, and in the solid areas between each of the alignment holes. Thus the user, simply by feeling or listening for a click, and looking into one of the snuffer-holes, can immediately tell which of the two alternative types of rims are in position at the base of the snuff-holes and consequently whether the ashtray can be used for extinguishing the lit end of a cigarette.
As will be apparent -to those skilled in the art in the light of the foregong disclosure, many Z
alterations and modifications are possible in the prac-tice of this invention without departing from the spirit or scope thereof. Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims.
