57 ABSTRACT A stackable safety ash tray having a flattened disha sd .bqs y wit .21 .ypwardly. exte ldinuiqewall 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 snufiing 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.
5 Claims, 5 Drawing Figures STACKABLE SAFETY ASH TRAY This invention is directed to a stackable ash tray. It is more specifically directed to a stackable safety type ash tray which provides a transverse elevated barrier positioned within the ash tray having integrally formed snuffing devices for a lighted cigarette.
As is well known, there are many ash trays on the market which provide pedestals and corrugations for the holding of a lighted cigarette. Anyone who has used this type of ash tray, however, is well aware that accidents do occur, such as when a lighted cigarette rolls from the edge of the ash tray onto furniture or carpets. Considerable damage and possible loss of life can result from accidents of this nature.
A problem also arises in the handling of ash trays when it is desired to store or carry these items. They are not only generally bulky, but because of the extensions, pedestals and the like, they seldom lend themselves to being stored in a small, compact area. This is especially true if a large number of ash trays must be stored or transported.
It is therefore an object of the present invention to provide an ash tray device which is easily stacked with a plurality of identical units, so as to provide an integral arrangement for easy carrying and storage.
A further object of the present invention is to provide an ash tray having snuffing devices provided centrally within the body which can be used to hold and quickly extinguish a lighted cigarette.
It is also an object of the present invention to provide an ash tray device which holds the cigarette in a position well within the boundaries of the outer edge of the ash tray to prevent the cigarette from rolling or falling from the device.
The present ash tray device consists of a relatively flat dish-shaped body having a narrow, generally vertical sidewall extending around the outer edge. A barrier for holding lighted cigarettes is arranged across the ash tray body. The central portion of the barrier is elevated above the sidewalls with the corners or ends of the barrier sloping downward, so that the barrier is joined to the sidewall at a point below the upper edge. Cylindrical recesses along the upper edge of the barrier are provided for holding the barrel of a lighted cigarette. The downward sloping ends of the barrier prevents a cigarette from being rested between the barrier and sidewall to prevent the cigarette from being overbalanced and possibly fall outside of the ash tray. One or more cigarette snuffing devices are incorporated in the barrier so that, by simply inserting the lit end of the cigarette without pressure, the cigarette will quickly be extinguished. By locating the snuffing devices close to the center of the ash tray, the cigarette is again prevented from accidentally falling from the ash tray.
The undersurface of the ash tray body, including the outer edge of the body and that portion under the barrier and snuffing devices, are recessed to conform to the upper surfaces of an identical ash tray, so that a plurality of the ash trays can be telescoped together in a stacked arrangement. When stacked, the ash trays form a continuously closed sidewall arrangement but still allow space within the ash tray cavity for cigarette stubs and ashes. This feature provides an additional advantage in that any burning material in the body cavity of the lower ash trays, when stacked, will be extinguished or suffocated. This feature is due to the telescoping of the outer edges of the sidewalls, which seals the cavity, cutting off the air to any lighted embers contained therein.
The ash trays described herein can be molded or formed as a one-piece unit which renders their manufacture simple and low-cost. They may be formed from any material desired, such as metal, ceramics, heat resistant plastics or the like. Manufacturing tolerances are not critical but must be adequate to provide a desirable close fit for stacking and removing of the units.
Other features of this invention will appear in the following description and appended claims, reference being made to the accompanying drawings forming a part of the specification wherein like referenced characters designate corresponding parts in the several views.
FIG. 1 is a perspective view of an ash tray device according to the present invention;
FIG. 2 is a top plan view of the ash tray device;
FIG. 3 is a side elevational view showing the elevated barrier and a second ash tray device in phantom lines in a stacked position;
FIG. 4 is a partial sectional view of the elevated barrier taken along line 4-4 of FIG. 2; and
FIG. 5 is a sectional view of the ash tray device taken along line 5-5 of FIG. 2 showing the recessed cavity formed in the underportion of the device.
Referring more specifically to FIG. 1, the safety ash tray device is shown as having a shallow, dish-shaped body 11 with a generally vertically narrow sidewall 12 disposed around the perimeter of the body 11. For the sake of illustration, the ash tray device shown herein is of a circular configuration. It is to be understood that any outer configuration, such as square, rectangle, oval or the like or even an irregular shape, can be provided as desired. The only requirement is that all stackable units must be of the same size and shape.
A barrier device 13 for supporting or holding lighted cigarettes is provided across the depression or cavity of the body. The barrier 13, again for the sake of iIlustra-' Y tion, is shown as a straight unit which is diammetrically arranged across the ash tray body 11. It, however, can be arranged in any position such as to form a chord of a circle or to form various segments by the use of a plurality of short sections. It is to be understood that any arrangement can be used as long as all units are identical.
The central portion 14 of the barrier device 13 is elevated above the upper edge 15 of the sidewall 12 and includes cylindrical depressions 13a for holding a lighted cigarette. (See FIG. 3) The outer comers l6, 17 of the barrier device 13 are bevelled downwardly at a sufiicient angle so that the barrier 13 is joined to the sidewall 12 at a point below its upper edge 15. The purpose in attaching the barrier at a point below the edge of the sidewall is to prevent a cigarette from being balanced or supported between the sidewall 12 and barrier 13. In this way, a cigarette can only be supported'within the confines of the outer sidewall of the ash tray, rendering it impossible for the cigarette to be overbalanced and fall from the ash tray.
Snuffing devices 18 are arranged generally vertical with respect to the barrier device 13. A tapered or bevelled upper edge 19 connecting with the internal stepped bore 20 of the snuffing device 18 is provided to aid in the insertion of a lighted cigarette. The diameter of the upper portion 21 of the bore 20 is large enough to permit the insertion of the cigarette therein, while the lower portion 22 of the bore 20 is of a smaller diameter, which restricts the passage of the cigarette. The intersection between the portions 21 and 22 forms a squared shoulder or step 20a which supports the lighted end of the cigarette. Thus, when a lighted cigarette is placed in an inverted position in the snuffing device, the tire is extinguished by suffocation without the necessity for crushing the end of the cigarette.
lower end 23 of the snuffing bore is open to the ash The tray cavity 28 and is tapered at an angle, so that the bore will remain open and not be clogged by cigarette debris.
As can be seen in FIGS. 4 and 5, recesses 24, are
provided in the undersurface of the ash tray device. In
the embodiment shown herein, the barrier device 13 is fabricated with an inverted V-shaped cross section which forms a recess 24 which is widest at the bottom edge, so that the upper end of a similar barrier device may be telescoped into the cavity provided. The internal recess 24 of the barrier device also communicates with an open, recess 25 formed by housing 26 which is provided directly under the snuffing devices and forms to the outer configuration of these devices.
With only the upper portion of the barrier device eleso that an ash retention cavity 28 will be retained within the ash tray. The outer recess 27 also provides a quasi-seal which restricts the passage of air into the cavity 28 when several ash trays are stacked together, so as to extinguish or suffocate any burning embers or materials that may remain within the ash tray. Thus, by
simply stacking a plurality of the ash trays together and leaving these units for a short period of time, a person can be certain that all burning materials within the ered ash trays have been extinguished.
It is important that the recess cavities 24, 25 formed COV- in the lower portion of the ash tray be positioned directly below and sized to correspond with the barrier configuration and snufiing devices used in the ash device. In this way, all units can be readily stacked, stored and removed, providing utmost convenience.
The thickness of the body and sidewall can be modified as desired to provide an easily molded structure which has sufficient strength to be a lasting and durable unit.
Although the individual parts of the ash tray may be machined and assembled, it may be more economical to form the ash tray according to this invention by a molding process where all parts are formed as an integral, one-piece unit.
While a stackable, safety type ash tray has been shown and described in detail, it is obvious that this invention is not to be considered as being limited to the exact form disclosed and that changes in detail and construction may be made therein within the scope of this invention without departing from the spirit thereof.
