IMPROVEMENTS IN CONTAINERS

摘要

A filled package 10 for the preparation of a foamed beverage or food product from a liquid primary ingredient 17 and air comprises at least one wall defining a chamber 11 containing the primary ingredient 17, an outlet 14 for dispensing the prepared product and air inlet 15 for selectively enabling the ingress of air into the chamber 11. The package 11 is resiliently deformable between an initial compressed position in which air is substantially evacuated from the package and an expanded position, such that when the ingress of air is enabled the package 11 recovers from the compressed position to its normal position sucking air into the chamber thereby mixing with the primary ingredient 17.
