Dispensing apparatus is primarily intended for dispensing product from product containers (12) by extrusion. In controlling discharge of product a flexible tube (25) is connected to the container outlet and the tube is engageable with drive means (29, 31) for deforming the tube and controlling product discharged along the tube to an outlet nozzle (26). Usually there will be valves towards the entry (27) and exit (28) of the flexible tube and the drive means engages the tube between the spaced positions.

The invention claimed is: 1. A method of dispensing semi-solid product by extrusion from a container of product, comprising: (a) applying pressure to the exterior of the container of product to cause the product to be discharged by extrusion through a container outlet from the container into a flexible tube; (b) controlling the flow of product from the container outlet through the flexible tube to an outlet nozzle, wherein controlling the flow of product comprises using a first inlet valve between the container outlet and the flexible tube and a second outlet valve between the flexible tube and the outlet nozzle; and (c) compressing the flexible tube using a drive means to express product from the flexible tube towards the outlet nozzle. 2. The method according to claim 1, wherein the first valve is opened to admit product into the flexible tube with the second valve closed, the first valve is then closed and the second valve opened, and the drive means is then operated to compress the flexible tube and express product in the flexible tube through said outlet nozzle downstream of the second valve. 3. The method according to claim 1, wherein operation of the drive means is controlled to express a predetermined portion of the product in the flexible tube through the nozzle, the size of the portion being adjustable to range between all the product in the flexible tube and a proportion of the product in the flexible tube. 4. The method according claim 1, wherein the drive means includes a tube engagement means which is movable reciprocally towards and away from the flexible tube to compress the flexible tube. 5. The method according to claim 1, wherein the first and second valves are spaced along the flexible tube to open and close the flexible tube by reciprocal movement to engage, deform and close the flexible tube at said spaced locations. 6. The method according to claim 1, wherein the container outlet is releasably connected to the flexible tube, the flexible tube extending towards the outlet nozzle which is shaped to shape a product discharged therethrough. 7. The method according to claim 1, wherein the drive means includes a tube engagement means moveable along the flexible tube towards the outlet nozzle to discharge the flexible tube contents. 8. The method according to claim 1, wherein the container and the flexible tube are contained within a refrigerated environment, the outlet nozzle projecting outwards from said environment. 9. The method according to claim 7, wherein the tube engagement means includes a roller which engages the flexible tube towards one end thereof and moves towards the outlet nozzle after said engagement. 10. An apparatus for dispensing semi-solid product, comprising: (a) a product container, the container having an outlet; (b) a pressurizing means for applying pressure to the exterior of the container to thereby extrude product from the outlet; (c) a flexible tube comprising a first end and a second end, the first end communicating with the outlet of the container and the second end communicating with a nozzle; (d) a drive means for engaging the flexible tube to deform the flexible tube and cause product in the flexible tube to be discharged through the nozzle; and (e) a valve means for controlling the flow of product from the nozzle, the valve means comprising a first valve adjacent to the nozzle, wherein the first valve controls the flow of product from the flexible tube to the nozzle, and a second valve between the outlet and the flexible tube to control flow of product to the flexible tube. 11. The apparatus according to claim 10, wherein the drive means includes a reciprocal drive member arranged to engage the flexible tube to deform and flatten the flexible tube to cause product in the flexible tube to be discharged from the nozzle. 12. The apparatus according to claim 10, wherein the outlet and the flexible tube are releasably connected to one another and the flexible tube is removable from the apparatus for replacement and/or sanitizing. 13. The apparatus according to claim 11, wherein the reciprocal drive member is moveable along the flexible tube towards said nozzle after engaging the flexible tube. 14. The apparatus according to claim 10, wherein the container and the flexible tube are located in a refrigerated housing to keep the product frozen, the nozzle projecting outwardly from the housing. 15. A method of dispensing semi-solid product by extrusion from a container of product, comprising: (a) applying pressure to the exterior of the container of product to cause the product to be discharged by extrusion through a container outlet from the container into a flexible tube; (b) controlling the flow of product from the container outlet through the flexible tube to an outlet nozzle; and (c) compressing the flexible tube using a drive means to express product from the flexible tube towards the outlet nozzle; wherein the container outlet is releasably connected to the flexible tube, the flexible tube extending towards the outlet nozzle which is shaped to shape a product discharged therethrough. 16. A method of dispensing semi-solid product by extrusion from a container of product, comprising: (a) applying pressure to the exterior of the container of product to cause the product to be discharged by extrusion through a container outlet from the container into a flexible tube; (b) controlling the flow of product from the container outlet through the flexible tube to an outlet nozzle; and (c) compressing the flexible tube using a drive means to express product from the flexible tube towards the outlet nozzle, wherein the drive means includes a tube engagement means movable along the flexible tube towards the outlet nozzle to discharge the flexible tube contents. 17. An apparatus for dispensing semi-solid product, comprising: (a) a product container, the container having an outlet; (b) a pressurizing means for applying pressure to the exterior of the container to thereby extrude product from the outlet; (c) a flexible tube comprising a first end and a second end, the first end communicating with the outlet of the container and the second end communicating with a nozzle; (d) a drive means for engaging the flexible tube to deform the flexible tube and cause product in the flexible tube to be discharged through the nozzle; and (e) a valve means for controlling the flow of product from the nozzle; wherein the outlet and the flexible tube are releasably connected to one another and the flexible tube is removable from the apparatus for replacement and/or sanitizing.
