## Abstract

Typical dispensers of liquids such as for beer often induce froth into the liquid as it is dispensed. This is not always desirable especially if too much froth is produced leading to waste. A liquid dispensing device (10) comprising a plurality of tubes (30) each tube having a diameter less than 2 mm is described to address the issue of over-frothing.

## Claims

### Claim 1

A beer dispensing device comprising a plurality of more than 100 tubes each tube having a diameter less than 0.75 mm, wherein each tube has a length in the range 40 to 7000 mm and wherein the tubes have a length:diameter ratio configured to establish laminar flow of the beer dispensed therethrough, in use; wherein the bores of the plurality of tubes are parallel with one another and the plurality of tubes are encased within an inner housing by friction-fit or by bonding.

### Claim 2 (depends on 1)

The beer dispensing device according to claim 1, comprising more than 200 tubes.

### Claim 3 (depends on 1)

The beer dispensing device according to claim 1, wherein the plurality of tubes has straight bores.

### Claim 4 (depends on 1)

The beer dispensing device according to claim 1, wherein the plurality of tubes has bores that are not circular.

### Claim 5 (depends on 1)

The beer dispensing device according to claim 1, wherein the plurality of tubes is fabricated as a single component.

### Claim 6 (depends on 1)

The beer dispensing device according to claim 1, wherein the device has an inlet end and an opposite outlet end, and the axes of the plurality of tubes at the inlet end are substantially parallel to the axes of the plurality of tubes at the outlet end.

### Claim 7 (depends on 1)

The beer dispensing device according to claim 1, wherein substantially all of the spaces between the plurality of tubes are blocked.
