Abstract
Abstract A method and apparatus for mixing a beverage includes a body through which a first stream of pressurized beverage concentrate is directed into a mixing zone in a spout, through which a second stream of water is directed and onto the first stream in such mixing zone, and through which a third stream of air is aspirated into the mixing zone by said first and second streams in the same general direction but away from the point of engagement between the first and second streams. The included angle between the first and second streams is gentle, but because of pressures used, the mixing is rather violent.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
A mixing device for beverage dispenser, comprising: a. a body having a beverage concentrate passage with an inlet for pressure concentrate, and a water passage with an inlet for pressurized water, said passages having spaced outlets, the axes of said passages converging at a point beyond said outlets; and b. a separate spout detachably secured to said body, said spout having a mixing portion in which said point is located, the axis of the mixing portion being horizontal, and a discharge portion of circular cross-section extending transversely to the axis of the mixing portion, the axis of said water passage being substantially tangent to said circular cross-section for swirling the mixture about the axis of said discharge portion, the cross-sectional flow area of said spout being at all points larger than the combined flow areas of said passage outlets.
Claim 2
Dependent Claim
139 words
A mixing device for beverage dispenser, comprising: a. a body having a beverage concentrate passage with an inlet for pressure concentrate, and a water passage with an inlet for pressurized water, said passages having spaced outlets, the axes of said passages converging at a point beyond said outlets; and b. a separate spout detachably secured to said body, said spout having a mixing portion in which said point is located, the axis of the mixing portion being horizontal, and a discharge portion of circular cross-section extending transversely to the axis of the mixing portion, the axis of said water passage being substantially tangent to said circular cross-section for swirling the mixture about the axis of said discharge portion, the cross-sectional flow area of said spout being at all points larger than the combined flow areas of said passage outlets.
Claim 3
Dependent Claim
33 words
A mixing device for a dispenser according to claim 1 in which said body has mounting means by which said beverage concentrate passage and said water passage are maintained in a horizontal plane.
Claim 4
Dependent Claim
31 words
A mixing device according to claim 1 in which the axis of said water passage in said body is substantially perpendicular to the axis of said discharge portion of said spout.
Claim 5
Dependent Claim
21 words
A mixing device according to claim 1 in which said passage outlets lie in a single flat surface of said body.
Claim 6
Dependent Claim
26 words
A mixing device accorDing to claim 1 in which the flow area of the water outlet is smaller than the flow area of the concentrate outlet.
Claim 7
Dependent Claim
31 words
A mixing device according to claim 1 in which said body has an air passage therethrough, the outlet of which is disposed adjacent to a surface extremity of said mixing portion.
