A dispensing assembly having a container containing a liquid to be dispensed and a dispensing tube bringing in fluid communication with ambient the volume inside the container containing the liquid. The dispensing tube has a flexible, resilient portion ending in an outlet of diameter, D, and is engaged in a pinch valve system. The pinch valve system has a squeezing member suitable for squeezing and obturating a section of the flexible portion located at a distance, h, from the outlet. The ratio, h/D, of the distance, h, to the outlet diameter, D, is not more than 2, preferably, not more than 1.5, more preferably, not more than 1.0.

1. A pressure driven dispensing assembly comprising a container containing a beverage to be dispensed, a dispensing tube bringing in fluid communication with ambient the volume inside the container containing the beverage, and a source of pressurized gas in fluid communication with the interior of the container for pressurizing the interior of the container and driving the dispensing of the beverage out of the container through the dispensing tube, said dispensing tube having a flexible, resilient portion ending in an outlet of inner diameter, D, is at least 3 mm, and being engaged in a pinch valve system comprising a squeezing member suitable for squeezing and obturating a single section of the flexible portion located at a distance, h, from the outlet comprised between 1 and 12 mm, wherein the ratio, h/D, of the distance, h, to the outlet inner diameter, D, is not more than 1.5, so as to reduce the dripping of the beverage out of the dispensing tube when obturating the section. 2. The dispensing assembly according to claim 1 wherein, (a) the container comprises a body, a mouth, and a closure, said closure comprising at least one dispensing opening;(b) the assembly further comprises an appliance suitable for receiving said container and for dispensing a beverage contained in said container, said appliance comprising a dispensing portion comprising the pinch valve system,(c) the dispensing tube has an inlet end introduced in the closure's dispensing opening in fluid contact with the interior of the container and the flexible portion is inserted in the valve of the dispensing portion and the outlet faces downwards. 3. The dispensing assembly according to claim 2, wherein the squeezing member can be moved from a “closed” position squeezing the flexible portion to an “open” position releasing the compressive pressure on the flexible portion by actuation of a lever. 4. The dispensing assembly according to claim 3, wherein the squeezing member comprises two complementary surfaces which can be moved relative to each other to be brought together with the flexible portion of the dispensing tube caught in between, and wherein at least one of the two complementary surfaces has a rounded portion in contact with the flexible tube portion of radius comprised between 0.2 and 3 mm. 5. The dispensing assembly according to claim 4, wherein the flexible portion of the dispensing tube is made of a natural or synthetic rubber, or a thermoplastic elastomer. 6. The dispensing assembly according to claim 5, wherein the dispensing tube is encased in a cartridge, forms smooth curves, and the longitudinal axes of the inlet and outlet form an angle, α, comprised between 85 and 145 deg. 7. The dispensing assembly according to claim 6, wherein the inlet end of the dispensing tube is suitable for unsealing an initially sealed dispensing opening of the container. 8. The dispensing assembly according to claim 1, wherein the container is a bag-in-container. 9. The dispensing assembly according to claim 8, wherein the beverage contained in the container is a carbonated beverage. 10. The dispensing assembly according to claim 1, wherein the squeezing member can be moved from a “closed” position squeezing the flexible portion to an “open” position releasing the compressive pressure on the flexible portion by actuation of a lever. 11. The dispensing assembly according to 1, wherein the squeezing member comprises two complementary surfaces which can be moved relative to each other to be brought together with the flexible portion of the dispensing tube caught in between, and wherein at least one of the two complementary surfaces has a rounded portion in contact with the flexible tube portion of radius comprised between 0.2 and 3 mm. 12. The dispensing assembly according to claim 1, wherein the flexible portion of the dispensing tube is made of a natural or synthetic rubber, or a thermoplastic elastomer. 13. The dispensing assembly according to claim 1, wherein the dispensing tube is encased in a cartridge, forms smooth curves, and the longitudinal axes of the inlet and outlet form an angle, α, comprised between 85 and 145 deg. 14. The dispensing assembly according to claim 1, wherein the beverage contained in the container is a carbonated beverage. 15. The dispensing assembly according to claim 14, wherein the beverage contained in the container is beer. 16. The dispensing assembly according to claim 1, wherein the ratio, h/D, of the distance, h, to the outlet inner diameter, D, is not more than 1.0.
