Ash tray equipped with disposable ash pocket
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an ash tray, and more particularly to an ash tray equipped with a plurality of disposable ash pockets having extinguisher. 
     2. Description of the Prior Art 
     In general, a home or a shop is provided with ash trays which are made of glass material or heat-resisting plastic material for the convenience of smokers. When the ash tray is filled with cigarette ashes and cigarette-butts, the ash tray should be cleaned out. In case of a shop such as a coffee shop, a used ash tray filled with ashes and cigarette-butts should be replaced with a cleaned ash tray whenever a customer is changed. Furthermore, the used ash tray should be cleaned to be reusable. 
     However, the work that every ash tray made of glass or heat-resisting plastic material should be replaced and cleaned whenever a customer is changed is troublesome and insanitary. In addition, since a smoker usually extinguishes cigarette by rubbing a light portion of the cigarette against an ash tray, the light of the cigarette may not be completely extinguished but remain for a long time, thereby causing smoke to rise from the cigarette for a long time. 
     SUMMARY OF THE INVENTION 
     The present invention has been made in view of the above-described problems occurring in the above-mentioned ash tray and an object of the invention is to provide an ash tray for eliminating the troublesome and insanitary work that it should be replaced and cleaned whenever a customer is changed. 
     In accordance with the present invention, the object of the invention can be accomplished by providing an ash tray comprising: an ash box; a plurality of disposable ash pockets inserted in the ash box which are stacked one in another; and means for extinguishing light of a cigarette which is disposed at a corner of the plurality of ash pockets. 
     The extinguishing means may be a conical extinguisher integrally formed with the ash pocket or a separable conical extinguisher.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Embodiments according to an ash tray of the present invention will be described with reference to the accompanying drawings hereinafter. 
     Referring to FIG. 1, there is shown an ash tray according to the invention. As shown in the drawing, the ash tray of the invention includes a cigarette box &#34;CA&#34; for receiving cigarette cases &#34;C&#34;, a match box &#34;FC&#34; for receiving matches &#34;F&#34; and an ash box 1 disposed between the cigarette box &#34;CA&#34; and the match box &#34;FC&#34;. The ash box 1 is provided therein with a plurality of disposable ash pockets 2 each having an extinguishing means at a corner. The plurality of disposable ash pockets 2 made of heat-resisting sheets are stacked one in another. 
     Referring to FIG. 2, there is shown the disposable ash pocket 2. As shown in the drawing, the disposable ash pocket 2 is formed at a corner with the extinguishing means. The extinguishing means comprises a conical extinguisher 3 which is formed by curling a portion of the sheet extended from the corner of the ash pocket 2. The extinguisher 3 has an upper diameter larger than a lower diameter. 
     In this embodiment, the disposable ash pocket 2 is prepared in such a manner that a vertical edge of the sheet forming the ash pocket is curled inward to form the extinguisher 3 and the other vertical edge is attached to the extinguisher 3. 
     Referring to FIGS. 3A and 3B, there are shown a plurality of stacked disposable ash pockets 2 illustrating usage thereof. When the plurality of disposable ash pockets 2 are stacked one another, the extinguisher 3 is folded to be flat, as shown in FIG. 3A. When the smoker uses the disposable ash pockets 2, the folded extinguisher 3 of the innermost ash pocket 2 is expanded into a conical shape by means of appropriate means. 
     When the innermost ash pocket 2 is filled with cigarette ashes and cigarette-butts, the innermost ash pocket 2 containing the ashes and cigarette-butts is taken out of the ash box 1 and then discarded. After the innermost ash pocket is taken out, the next innermost ash pocket 2&#39; is automatically prepared with the folded extinguisher 3&#39; and then the folded extinguisher 3&#39; is also expanded into a conical shape. 
     In this embodiment, since the folded extinguisher 3 or 3&#39; is disposed at a corner of the ash pocket 2, the extinguisher 3 may be bulged inward if the plurality of ash pockets 2, 2&#39; are stacked in the same orientation. For overcoming the bulging problem, the plurality of ash pockets 2, 2&#39; are stacked one another in such a manner that the adjacent extinguisher 3, 3&#39; are disposed at interval of the right angle in one direction. 
     Referring to FIG. 4, there is shown an ash pocket according to another embodiment of the invention. As shown in the drawing, the ash pocket 2&#34; is a simple hexahedron opening upward and a plurality of ash pockets 2&#34; are stacked one another. The stacked ash pockets 2&#34; are provided therein with a separable extinguisher 3&#34; having a clip 4. Therefore, the separable extinguisher 3&#34; can be mounted on the ash pockets 2&#34; by means of its clip 4. The ash pocket 2 equipped with the separable extinguisher 3&#34; according to this embodiment has the same effect as that of the previous embodiment. 
     As apparent from the above description, since the ash tray of the invention includes a plurality of stacked disposable ash pockets and an extinguisher integrally formed with or detachably attached to the ash pockets, the innermost ash pocket can be taken out of the next ash pocket to be discarded and the next fresh ash pocket can be prepared automatically after the innermost ash pocket is filled with ashes and cigarette-butts. Therefore, the ash tray of the invention can eliminate a troublesome job of replacement and cleaning of a used ash tray. 
     Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
