The invention provides a container of substantially form-retaining material, for instance aluminum, steel or other metal, or PET (polyethylene terephthalate) or other plastic, for a liquid, which must be provided prior to consumption with a foaming head, such as chocolate milk, cappuccino, milkshake
The invention provides a container of substantially form-retaining material, for instance aluminum, steel or other metal, or PET (polyethylene terephthalate) or other plastic, for a liquid, which must be provided prior to consumption with a foaming head, such as chocolate milk, cappuccino, milkshake, which container comprises: a circumferential wall; a base which is connected along its whole periphery to this wall or is integrally formed therewith; a cover which, after filling of the container with the liquid, is optionally arranged on the side remote from the base and which is connected to this wall along its whole periphery; and; a cartridge present in the container and in the filled and closed situation of the container at least partially filled with a gas under pressure serving as foaming medium in the wall of which cartridge is situated at least one continuous hole for passage of gas.

The invention claimed is: 1. Container of substantially form-retaining material, which container is filled with a liquid, which must be provided prior to consumption with a foaming head, which liquid comprises dissolved therein a first gas, which container comprises: a circumferential wall; a base
The invention claimed is: 1. Container of substantially form-retaining material, which container is filled with a liquid, which must be provided prior to consumption with a foaming head, which liquid comprises dissolved therein a first gas, which container comprises: a circumferential wall; a base which is connected along its whole periphery to this wall or is integrally formed therewith; a cover which, after filling of the container with the liquid, is connected to the circumferential wall along its whole periphery; and a cartridge present in the container and at least partially filled with a second gas which under pressure serves as foaming medium, in the wall of which cartridge is situated at least one continuous hole for passage of gas; and in the free container space a second gas creating over pressure in the closed container; wherein the first gas is nitrous oxide, and the second gas is nitrogen, and wherein the nitrous oxide and nitrogen, in combination, provide the liquid with a stiff foaming head that is stable for 15 minutes at refrigerator temperatures. 2. Container as claimed in claim 1, wherein the gas contains an aromatic component. 3. Container as claimed in claim 1, comprising: a cartridge which is coupled to the base and extends from the base over some axial distance and which defines two passages, the first of which is situated in an end wall of the cartridge remote from the base and the second of which is situated in the region of the base; which cartridge has the general shape of a beaker which beaker is coupled with an edge zone of its mouth to the base of the container by means of coupling means; wherein the coupling means are exclusively mechanical and are embodied such that between the edge zone of the cartridge and the base of the container there remains some space, which space defines the second passage. 4. Container as claimed in claim 3, wherein the base has an axially displaced part with at least partly undercut peripheral zone; and the edge zone of the cartridge takes an at least partly undercut form; which peripheral zone and which edge zone mutually engage while retaining a clearance such that the cartridge is coupled to the base. 5. Container as claimed in claim 4, wherein the coupling means comprise snap means. 6. Container as claimed in claim 4, wherein at least one of the peripheral zone and the edge zone is compressed at least partially in axial direction while enclosing the other. 7. Container as claimed in claim 3, wherein the first passage has a form narrowing toward an area outside of the cartridge. 8. Container as claimed in claim 7, wherein the first passage has length of (3짹1) mm, an entry diameter of (0.9짹0.2) mm and an exit diameter of (0.25짹0.05) mm. 9. Container as claimed in claim 3, wherein the first passage is formed by perforation. 10. Container as claimed in claim 7, wherein the first passage is made by perforating with a bradawl having a conical tip. 11. Container as claimed in claim 10, wherein the tip of the bradawl has a shape corresponding with the shape of the passage and is displaced relative to the end wall of the cartridge over an axial distance corresponding with the desired shape of the passage. 12. Container as claimed in claim 3, wherein the exit of the first passage does not protrude axially beyond the peripheral edge of the end wall. 13. Container as claimed in claim 12, wherein the end wall has a recess. 14. Container as claimed in claim 1, wherein the cartridge consists substantially of the same material as the container. 15. Container as claimed in claim 1, wherein at least a part of the inner surface of the container and the surfaces of the cartridge are provided with a coating. 16. Method for preparing a beverage container containing a consumable liquid so that the liquid will provide a foaming head upon opening the container for consumption, comprising the following steps: providing a container comprising a circumferential wall, a base which is connected along its whole periphery to this wall or is integrally formed therewith, and a cover which, after filling of the container with the liquid, is connected to the circumferential wall along its whole periphery; accommodating a cartridge in the container, the cartridge being at least partially filled with nitrogen under pressure serving as foaming medium; filling consumable liquid into the container, dissolving nitrous oxide in the liquid, and closing the container, and wherein the nitrous oxide and nitrogen, in combination, provide the liquid with a stiff foaming head that is stable for 15 minutes at refrigerator temperatures. 17. Method according to claim 16, wherein nitrous oxide is dissolved in the liquid after filling the liquid into the container. 18. Method according to claim 16, wherein the liquid is selected from chocolate milks, cappuccinos, and milkshakes. 19. Container as claimed in claim 1, wherein the said form-retaining materials is selected from the group consisting of aluminum, steel, other metal, polyethylene terephthalate, and other plastic. 20. Container as claimed in claim 1, wherein the liquid is selected from chocolate milk, cappuccino, and milkshake. 21. Container as claimed in claim 15, wherein the coating is a lacquer coat. 22. Container as claimed in claim 1, wherein the liquid is non-alcoholic. 23. Method as claimed in claim 16, wherein the liquid is non-alcoholic.
