Fire-safe disposal bags for smokers' receptacles

Abstract

A disposable, fireproof receptacle for combustible debris for use in a cigarette receptacle is disclosed. The liner may be made from a metallic foil or other inexpensive, fire resistant material. The liner may be used in combination with or without a pail inside the receptacle. The metallic foil makes the liner resistant to fire and is inexpensive enough to also be disposable. When filled with debris the liner can be removed and sealed to allow convenient, safe disposal of the grimy and potentially hot debris inside the liner.

1 . A receptacle for combustible debris comprising:
 a base having at least one wall defining an interior chamber;   a removable cover atop the base having an opening for receiving the combustible debris;   a pail positioned under the opening of the removable cover and inside the interior chamber;   a fireproof, disposable liner inside the pail.   
   
   
       2 . The receptacle for combustible debris of  claim 1 , wherein the fireproof, disposable liner is metallic foil. 
   
   
       3 . The receptacle for combustible debris of  claim 2 , wherein the metallic foil is selected from the group consisting of aluminum, aluminum alloys, steel and steel alloys. 
   
   
       4 . The receptacle for combustible debris of  claim 2 , wherein the metallic foil has a gauge of about 0.5 mil to about 5 mils. 
   
   
       5 . The receptacle for combustible debris of  claim 4 , wherein the metallic foil has a gauge of about 1 mil to about 4 mils. 
   
   
       6 . The receptacle for combustible debris of  claim 1 , wherein the liner has a volume of about 1 quart to about 30 quarts. 
   
   
       7 . The receptacle for combustible debris of  claim 1 , wherein the liner comprises a single radial wall attached to a liner bottom. 
   
   
       8 . The receptacle for combustible debris of  claim 1 , wherein the liner comprises two opposing sheets of metallic foil sealed, wherein the each sheet is sealed to the other along at least two edges. 
   
   
       9 . A receptacle for combustible debris comprising:
 a base having at least one wall defining an interior chamber;   a removable cover atop the base having an opening for receiving the combustible debris;   a fireproof, disposable liner positioned under the opening of the removable cover and inside the interior chamber.   
   
   
       10 . The receptacle for combustible debris of  claim 9 , wherein the fireproof, disposable liner is metallic foil selected from the group consisting of aluminum, aluminum alloys, steel and steel alloys. 
   
   
       11 . A method of emptying a cigarette butt receptacle comprising the steps of:
 removing a cover from the cigarette butt receptacle;   removing a fireproof liner at least partially filled with cigarette butts or other debris;   folding and rolling a top edge of the fireproof liner upon other portions of the top edge of the fireproof liner to close the liner;   disposing of the liner and debris;   positioning a new liner into the cigarette butt receptacle; and   replacing the cover on the cigarette butt receptacle.
