Improvements in containers are provided, and in particular improvements in containers for preparing and dispensing foamable beverage and food products. The package may contain at least a liquid primary ingredient and a secondary ingredient and comprises at least one wall defining a chamber at least partially filled with the primary ingredient, an outlet for dispensing the prepared product, and a capsule surrounding the primary ingredient separating the secondary ingredient from the primary ingredient. The capsule may be attached to insides of opposing walls of the package such that as the opposing walls are moved further apart the capsule breaks. At least one of the ingredients may include a foaming agent such that the foamed product is produced when the capsule is broken and the primary and secondary ingredients mix.

A package for preparation of a foamed beverage or food product containing at least a liquid primary ingredient and a secondary ingredient, the package comprising at least one wall defining a chamber at least partially filled with the primary ingredient, an outlet for dispensing a prepared product

1. A package for preparation of a foamed beverage or food product containing at least a liquid primary ingredient and a secondary ingredient, the package comprising at least one wall defining a chamber at least partially filled with the primary ingredient, an outlet for dispensing a prepared product, and a capsule surrounding the primary ingredient separating the secondary ingredient from the primary ingredient, the capsule being attached to insides of opposing walls of the package with the ability to break when the opposing walls are moved further apart, wherein at least one of the ingredients includes a foaming agent for producing a foamed product when the capsule is broken and the primary and secondary ingredients mix; and an air inlet device for selectively enabling ingress of air into the chamber,wherein the air inlet device comprises a one way valve in the at least one wall. 2. The package as claimed in claim 1, wherein the package is resiliently deformable between a normal expanded position and a compressed position so that movement from the compressed position to the expanded position breaks the capsule. 3. The package as claimed in claim 2, wherein manual pressure is applied to break the capsule. 4. The package as claimed in claim 1 further comprising a device for selectively opening and closing the outlet. 5. The package as claimed in claim 1, wherein the outlet provides the air inlet device. 6. The package as claimed in claim 1, wherein the outlet comprises a nozzle. 7. The package as claimed in claim 6, wherein the outlet provides a path, the construction of which aids generation of foam. 8. A package for preparation of a foamed beverage or food product containing at least a liquid primary ingredient and a secondary ingredient, the package comprising at least one wall defining a chamber at least partially filled with the primary ingredient, an outlet for dispensing a prepared product, and a capsule surrounding the primary ingredient separating the secondary ingredient from the primary ingredient, the capsule being attached to insides of opposing walls of the package with the ability to break when the opposing walls are moved further apart, wherein at least one of the ingredients includes a foaming agent for producing a foamed product when the capsule is broken and the primary and secondary ingredients mix; and an air inlet device for selectively enabling ingress of air into the chamber,wherein the air inlet device comprises a plurality of apertures in the at least one wall of a size which allows the ingress of air into the chamber but substantially prevents egress of liquid from the chamber. 9. The package as claimed in claim 8, wherein the package is resiliently deformable between a normal expanded position and a compressed position so that movement from the compressed position to the expanded position breaks the capsule. 10. The package as claimed in claim 9, wherein manual pressure is applied to break the capsule. 11. The package as claimed in claim 8 further comprising a device for selectively opening and closing the outlet. 12. The package as claimed in claim 8 wherein the outlet provides the air inlet device. 13. The package as claimed in claim 8, wherein the outlet comprises a nozzle. 14. The package as claimed in claim 13, wherein the outlet provides a path, the construction of which aids generation of foam. 15. A method of preparing a foamed beverage or food product from a liquid primary ingredient and a secondary ingredient from a package as claimed in claim 1, comprising the steps of breaking the capsule separating the secondary ingredient from the primary ingredient to enable the primary and secondary ingredients to mix and foam, opening the outlet and squeezing the package to dispense the prepared product via the outlet.
