Abstract
Abstract The invention discloses a machine for dispensing carbonated liquid into a cup to provide a beverage. The carbonated liquid is dispensed from a tank to an outlet through a passage which comprises a section of curved elongated form (235) and having a progressively increasing cross section so that there will be a smooth reduction in carbonation between the tank and the outlet to avoid excessive foaming of the beverage as it issues from the outlet.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
172 words
A dispenser for carbonated liquid comprising: i) a supply of carbonated liquid (11) at above atmospheric pressure; ii) an assembly comprising first and second relatively movable parts (189, 181); iii) an i (135) in said assembly and coupled to said supply (11); iv) an outlet (237) from said assembly from which carbonated liquid may be dispensed; v) a flow passage (99, 103, 235, 237) through said assembly and connecting said inlet (135) and outlet (237); vi) a valve (107, 109) in said flow passage and controlling flow of carbonated liquid through the flow passage depending upon relative movements of said parts; vii) means (191) for relatively moving said parts to control said valve (107, 109); characterised in that a length (235) of said flow passage comprises an elongated curved expansion chamber of increasing cross section in a direction towards the outlet (237) for reducing the pressure and velocity of carbonated liquid flowing into said chamber before it reaches said outlet (237) so as to minimise loss of carbonation in the dispensed liquid.
Claim 2
Dependent Claim
172 words
A dispenser for carbonated liquid comprising: i) a supply of carbonated liquid (11) at above atmospheric pressure; ii) an assembly comprising first and second relatively movable parts (189, 181); iii) an i (135) in said assembly and coupled to said supply (11); iv) an outlet (237) from said assembly from which carbonated liquid may be dispensed; v) a flow passage (99, 103, 235, 237) through said assembly and connecting said inlet (135) and outlet (237); vi) a valve (107, 109) in said flow passage and controlling flow of carbonated liquid through the flow passage depending upon relative movements of said parts; vii) means (191) for relatively moving said parts to control said valve (107, 109); characterised in that a length (235) of said flow passage comprises an elongated curved expansion chamber of increasing cross section in a direction towards the outlet (237) for reducing the pressure and velocity of carbonated liquid flowing into said chamber before it reaches said outlet (237) so as to minimise loss of carbonation in the dispensed liquid.
Claim 3
Dependent Claim
32 words
A dispenser according to Claim 1, characterised in that said relatively movable parts comprise a holder (181) having a cylindrical bore (182), and a rotatable disc (189) rotatably contained in said bore.
Claim 4
Dependent Claim
20 words
A dispenser according to Claim 1, characterised in that the said expansion chamber (235) is in said rotatable disc (189).
Claim 5
Dependent Claim
27 words
A dispenser according to Claim 3, characterised in that said expansion chamber extends around the disc (189) by an extent to subtend an angle of approximately 90°.
Claim 6
Dependent Claim
38 words
A dispenser according to any of Claims 2 to 4, characterised in that the said valve (107, 109) comprises an aperture (107) in said holder (182), an aperture (231) in the disc (189), and an O-ring seal (109).
Claim 7
Dependent Claim
36 words
A dispenser according to any of Claims 2 to 4, characterised in that the said means (191) for relatively moving the said holder (181) and disc (189) comprises a lever (191) integral with the disc (189).
