Abstract
Abstract A die cut wick for use in a burner having a rectangular body that contains two half sections that are folded back into a face to face alignment. Each half section further contains a tab upwardly disposed from the top surface of the body, the tabs being centrally positioned on the half sections with the top surface of the body extending laterally to either side to form a shoulder. The tabs of the wick are folded against each other and passed upwardly through a hollow stud secured to the lid of the fuel container. The shoulders of the tabs abut the bottom surface of the lid to prevent the tabs from being drawn entirely through the stud and the body is secured to the bottom of the lid using holt melt glue or the like. The end of the tabs extend beyond the top of the stud to form the flame region of the burner. The end of the tabs extend beyond the top of the stud to form the flame region of the burner. The burning rate and heat output of the flame is controlled by separating the exposed ends of the tabs.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
130 words
A die cut wick that is formed from a single sheet of wicking material for use in a disposable burner that includes a body having a planar top surface, said body containing a slit extending along a portion of its longitudinal axis to divide the body into two half sections, each half section further including a tab upwardly disposed from said top surface, each tab being centrally positioned upon the half section and having a width that is less than the width of the half section so that the top surface of the body forms a laterally extended shoulder at the base of each tab whereby the wick can be folded back upon itself along the line described by the slit to place the tabs in face to face alignment.
Claim 2
Dependent Claim
130 words
A die cut wick that is formed from a single sheet of wicking material for use in a disposable burner that includes a body having a planar top surface, said body containing a slit extending along a portion of its longitudinal axis to divide the body into two half sections, each half section further including a tab upwardly disposed from said top surface, each tab being centrally positioned upon the half section and having a width that is less than the width of the half section so that the top surface of the body forms a laterally extended shoulder at the base of each tab whereby the wick can be folded back upon itself along the line described by the slit to place the tabs in face to face alignment.
Claim 3
Dependent Claim
21 words
The wick of claim 1 whereby the width of the said tabs is about half the width of each half section.
Claim 4
Dependent Claim
30 words
The wick of claim 1 whereby the slit formed in the body is completely surrounded with wick material and is at least one third the entire length of the body.
Claim 5
Dependent Claim
24 words
The wick assembly of claim 3 wherein the slit is located at the upper part of the body immediately below the top surface thereof.
Claim 6
Dependent Claim
175 words
A burner unit that includes an open topped container for holding a quantity of liquid fuel, a single piece wick having a body that is divided along a longitudinal axis into two half sections, each half section further including a raised tab that is positioned upon the top surface thereof, each tab having a width that is less than the width of the half section and being folded over into face to face alignment whereby a shoulder extends to either side of the tabs at their base, a lid for closing the top of the container, a raised stud vertically mounted in the lid having a length that is less than the extended length of said tabs, said stud having an opening that passes into the container for slidably receiving the tabs therein with the tab shoulders in abutting contact against the bottom surface of the lid and the ends of the tabs extending above the top of the stud, and means to secure the body of the wick to the bottom of the lid.
Claim 7
Dependent Claim
175 words
A burner unit that includes an open topped container for holding a quantity of liquid fuel, a single piece wick having a body that is divided along a longitudinal axis into two half sections, each half section further including a raised tab that is positioned upon the top surface thereof, each tab having a width that is less than the width of the half section and being folded over into face to face alignment whereby a shoulder extends to either side of the tabs at their base, a lid for closing the top of the container, a raised stud vertically mounted in the lid having a length that is less than the extended length of said tabs, said stud having an opening that passes into the container for slidably receiving the tabs therein with the tab shoulders in abutting contact against the bottom surface of the lid and the ends of the tabs extending above the top of the stud, and means to secure the body of the wick to the bottom of the lid.
Claim 8
Dependent Claim
29 words
The burner assembly of claim 5 wherein the length of the stud is less than that of the tabs so that a predetermined length of the tabs is exposed.
Claim 9
Dependent Claim
36 words
The burner assembly of claim 5 wherein the body of the wick contains a slit along a portion of its longitudinal axis whereby the half sections can be folded back along the line of the slit.
Claim 10
Dependent Claim
18 words
The burner assembly of claim 5 that further includes seam means for sealing the lid to the container.
Claim 11
Dependent Claim
27 words
The burner assembly of claim 5 that further includes an elongated cap that is capable of being press fitted upon the stud to close the stud opening.
Claim 12

The burner of claim 5 wherein the means for securing the body of the wick to the lid is a hot melt glue.
Claim 13
Dependent Claim
104 words
A die cut wick that is formed from a single sheet of wicking material suitable for use in a fuel burner, said wick including a body having a plannar top surface that can be folded back upon itself along a lateral centerline that is perpendicular to said plannar surface to form two half sections, each half section including at least one tab that is upwardly disposed from said plannar surface and having a width that is less than the width of the half section so that the top surface of the body forms a shoulder that extends laterally from the base of each tab.
Claim 14
Dependent Claim
104 words
A die cut wick that is formed from a single sheet of wicking material suitable for use in a fuel burner, said wick including a body having a plannar top surface that can be folded back upon itself along a lateral centerline that is perpendicular to said plannar surface to form two half sections, each half section including at least one tab that is upwardly disposed from said plannar surface and having a width that is less than the width of the half section so that the top surface of the body forms a shoulder that extends laterally from the base of each tab.
