Clear chaffer fuel canister

Abstract

The clear chaffer fuel canister of the present invention allows the users to determine the hours of burn time remaining in relation to the volume of fuel remaining. Visual indicators on the clear base vessel correspond to the predetermined burn time remaining. The volume of fuel, as it reaches the visual indicators provides the user a quick and reliable means of determining the burn time remaining with the clear chaffer fuel canister. The burn time remaining is an essential feature, as clear chaffer fuel canisters are generally used in the food industry in maintaining the proper temperature of prepared food. The burn time remaining provides an indication to the users and allows the users to determine the optimal time to replace the clear chaffer fuel canister and maintain the appropriate temperature of the displayed food.

1 . A clear chaffer fuel canister comprising:
 a) a clear base vessel having a transparent composition and constructed with an attachment lip surrounding a cavity orifice defining a cavity;   b) a chaffer vessel lid set within the cavity orifice of the clear base vessel and sealed to produce a water tight seal through an interaction between a step hook of the chaffer vessel lid and the attachment lip of the clear base vessel;   c) fuel encapsulated within a cavity of the clear base vessel;   d) a protruding neck formed on an outer surface of the chaffer vessel lid for receiving a wick partially submerged into the fuel within the clear base vessel cavity and extending partially out of the protruding neck; and,   e) the fuel within the cavity of the clear base vessel consumed when an extended portion of the wick is ignited;   wherein the fuel housed within the clear base vessel can be viewed and its current volume assessed in relation to burn time remaining through visual inspection.   
     
     
         2 . The clear chaffer fuel canister of  claim 1 , further comprising a clear base vessel with a wall thickness between 0.60 cm and 1.20 cm. 
     
     
         3 . The clear chaffer fuel canister of  claim 1 , further comprising a clear base vessel with an attachment lip thickness between 0.25 cm and 0.45 cm. 
     
     
         4 . The clear chaffer fuel canister of  claim 1 , further comprising a clear base vessel with a plastic composition containing polypropylene. 
     
     
         5 . The clear chaffer fuel canister of  claim 1 , further comprising a clear base vessel with a plastic composition containing polypropylene and a resin. 
     
     
         6 . The clear chaffer fuel canister of  claim 1 , wherein the clear base vessel comprises a plastic material having a softening point between 120° C. and 130° C. 
     
     
         7 . The clear chaffer fuel canister of  claim 1 , wherein the fuel is diffused to the extending portion of the wick through capillary action of the wick. 
     
     
         8 . The clear chaffer fuel canister of  claim 1 , further comprising a clear base vessel with visual indicators outlining the burn time remaining as based on fuel remaining within the clear base vessel. 
     
     
         9 . The clear chaffer fuel canister of  claim 1 , wherein the step hook of the chaffer vessel lid is mechanically molded around the attachment lip of the clear base vessel to produce a water tight seal. 
     
     
         10 . A method of manufacture of the clear chaffer fuel canister of  claim 1  comprising of the following steps:
 a) a plastic or plastic mix is chosen and liquified through addition of heat up to 165° C. for 15-30 minutes; 
 b) the liquified plastic or plastic mix is inspected for complete liquification and mixed thoroughly; 
 c) the liquified plastic or plastic mix is injected into a precast mold die representing the clear base vessel; 
 d) pressure is applied to the liquified plastic or plastic mix which has been injected into the precast mold die; 
 e) the liquified plastic or plastic mix is allowed to set within the mold die for 15 to 45 minutes; 
 f) the liquified plastic or plastic mix is allowed to cool, using a cooling technique that prevents formation of crystals within the plastic; 
 g) the solid clear base vessel, which is formed from the solidification of the liquified plastic or plastic mix is removed from the mold die; 
 h) the clear base vessel is inspected for any irregularities and if found, is recycled back to the plastic or plastic mix that is to be heated to 165° C.; 
 i) the precast chaffer vessel lid is set within the cavity orifice of the clear base vessel; 
 j) the step hook of the precast chaffer vessel lid is aligned with the attachment lip of the clear base vessel; 
 k) a modified chuck is run across the step hook thereby mechanically sealing the step hook onto the attachment lip of the clear base vessel; 
 l) fuel is poured into the aperture of the chaffer vessel lid and a wick is set partially within the cavity of the clear base vessel; 
 m) the wick is sealed within the bore of the protruding neck of the chaffer vessel lid; and, 
 g) a flame cap is fastened onto the protruding neck of the chaffer vessel lid.
