Methods, capsule and apparatuses for the production of foamed drinks
First Claim
1. A method for the preparation of a foamed drink comprising the steps of:
- providing a capsule containing a foamable ingredient;
providing a receptacle positioned to collect fluid escaping from the capsule;
injecting liquid into the capsule to mix with the foamable ingredient;
allowing the foamable ingredient mixed with the liquid to escape from the capsule into the receptacle;
followed by injecting further liquid into the receptacle through a nozzle separate from said capsule in a jet having a diameter of from about 0.5 mm to about 2 mm to produce foamed liquid in the receptacle.

26. A method of preparing a foamed drink comprising the steps of:
-
providing a capsule comprising side walls defining an enclosed region containing a foamable ingredient, an inlet for injecting a liquid into the said region, and an outlet for allowing liquid to escape from the said region, wherein said inlet comprises a constriction for providing a liquid jet having a diameter of from about 0.5 mm to about 2 mm; injecting an aqueous liquid under pressure into the inlet; allowing the foamable ingredient to mix with the aqueous liquid in the capsule; followed by allowing the aqueous liquid to escape through the outlet of the capsule and into a receptacle as a high velocity jet.
