Abstract
Abstract A dispenser (100) for solder flux includes a first solder flux reservoir (110) with a dispensing tip (118) at one end thereof for dispensing solder flux (112) in response to a frictional pressure applied to the tip. A second solder flux reservoir (102) is also included having a dispensing channel (106) for dispensing solder flux (104) responsive to a pressure applied to the flux (104) within the second solder flux reservoir (102).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
98 words
A dispenser for solder flux, comprising: a first solder flux reservoir having a dispensing tip at one end thereof for dispensing solder flux responsive to a frictional pressure applied to the tip; and a second solder flux reservoir substantially surrounding the first solder flux reservoir and dispensing solder flux separate from the first solder flux reservoir, and having a dispensing channel for dispensing solder flux responsive to pressure applied to the flux within the second solder flux reservoir, the first and second solder flux reservoirs being capable of dispensing the solder flux substantially independent one of the other.
Claim 2
Dependent Claim
98 words
A dispenser for solder flux, comprising: a first solder flux reservoir having a dispensing tip at one end thereof for dispensing solder flux responsive to a frictional pressure applied to the tip; and a second solder flux reservoir substantially surrounding the first solder flux reservoir and dispensing solder flux separate from the first solder flux reservoir, and having a dispensing channel for dispensing solder flux responsive to pressure applied to the flux within the second solder flux reservoir, the first and second solder flux reservoirs being capable of dispensing the solder flux substantially independent one of the other.
Claim 3
Dependent Claim
38 words
The dispenser of claim 1, wherein the first solder flux reservoir includes an air channel for providing a volume of air into the first solder flux reservoir to facilitate the dispensing of the solder flux from the tip.
Claim 4
Dependent Claim
30 words
The dispenser of claim 1, wherein the first solder flux reservoir includes an absorbent member for holding the solder flux in the first solder flux reservoir until it is dispensed.
Claim 5
Dependent Claim
23 words
The dispenser of claim 1, wherein the tip of the first solder flux reservoir comprises a felt tip having an angled end portion.
Claim 6
Dependent Claim
67 words
A dispenser for solder flux, comprising: an inner solder flux reservoir having a dispensing tip at one end thereof for dispensing solder flux responsive to a frictional pressure applied to the tip; and an outer solder flux reservoir substantially surrounding the inner solder flux reservoir and having a dispensing channel for dispensing solder flux responsive to pressure applied to the flux within the outer solder flux reservoir.
Claim 7
Dependent Claim
67 words
A dispenser for solder flux, comprising: an inner solder flux reservoir having a dispensing tip at one end thereof for dispensing solder flux responsive to a frictional pressure applied to the tip; and an outer solder flux reservoir substantially surrounding the inner solder flux reservoir and having a dispensing channel for dispensing solder flux responsive to pressure applied to the flux within the outer solder flux reservoir.
Claim 8
Dependent Claim
32 words
The dispenser of claim 5, wherein the inner solder flux reservoir includes an air channel for providing a volume of air to facilitate the dispensing of the solder flux from the tip.
Claim 9
Dependent Claim
30 words
The dispenser of claim 5, wherein the inner solder flux reservoir includes an absorbent member for holding the solder flux in the inner solder flux reservoir until it is dispensed.
Claim 10
Dependent Claim
23 words
The dispenser of claim 5, wherein the tip of the inner solder flux reservoir comprises a felt tip having an angled end portion.
