A beverage dispensing apparatus is provided. The apparatus includes a container containing a beverage to be dispensed. Pressurizing means are provided for increasing the pressure in the interior of the container. A dispensing duct brings in fluid communication the liquid beverage contained in the container with the exterior environment and draws the beverage out of the container. The dispensing duct comprises a dispensing pipe opening to ambient via a valve, and a pressure reducing channel with an opening connecting in fluid communication the interior of the container with the dispensing pipe. The pressure reducing channel is disposed in a housing made of two half bodies joined together. Each body includes a matching open channel forming the closed pressure reducing channel upon joining. At least one of the half bodies is an integral part of either the container's closure or the chime.

1. A beverage dispensing apparatus for dispensing a beverage comprising: a container containing a beverage to be dispensed, wherein the container's opening is closed with a closure and the container includes a chime;pressurizing means for increasing the pressure in the interior of the container; and
1. A beverage dispensing apparatus for dispensing a beverage comprising: a container containing a beverage to be dispensed, wherein the container's opening is closed with a closure and the container includes a chime;pressurizing means for increasing the pressure in the interior of the container; anda dispensing duct bringing in fluid communication the liquid beverage contained in the container with the exterior, for drawing beverage out of the container, said dispensing duct comprising: a dispensing pipe opening to ambient via a valve; anda pressure reducing channel with an opening connecting in fluid communication the interior of the container with the dispensing pipe;wherein, the pressure reducing channel is disposed in a housing made of two half bodies joined together, each body comprising a matching open channel forming the closed pressure reducing channel upon joining, and wherein at least one of the half bodies is an integral part of the chime, and wherein the housing comprises also a through channel fluidly connecting the external surface of the first half body with the external surface of the second half body, for the injection of propellant gas into the container. 2. The dispensing apparatus according to claim 1, wherein the pressure reducing channel is curved and/or has a varying cross-sectional area. 3. The dispensing apparatus according to claim 1, wherein the two half bodies are injection moulded and joined by gluing, welding, over-injection, or by any mechanical fastening means. 4. The dispensing apparatus according to claim 1, wherein the open channel in one of the two half bodies is provided with walls and the open channel of the other half body is provided with corresponding recesses to ensure alignment of the two half bodies upon joining and to ensure fluid tightness of the closed channel. 5. The dispensing apparatus according to claim 1, wherein components of the dispensing pipe are integral parts of the half bodies. 6. The dispensing apparatus according to claim 1, which is a disposable home beer dispenser. 7. The dispensing apparatus according to claim 1, wherein the housing comprising the channel is made of polypropylene. 8. The dispensing apparatus according to claim 1, wherein the channel comprises at least one sharp bend. 9. A method for producing a pressure reducing channel for reducing the pressure of a liquid flowing through a dispensing duct of a pressure driven beverage dispensing apparatus according to claim 1, said method comprising the following steps: injection moulding two half bodies of a housing, each half body comprising on their inner surface an open channel matching the open channel of the other half;bringing the two half bodies in abutting relationship, with the open channel of one half body vis-à-vis the open channel of the other half body to thus form a closed channel; andjoining the two half bodies to yield a fluid tight channel;wherein at least one of the half bodies is an integral part of a chime of a container containing the beverage to be dispensed. 10. The method according to claim 9, wherein the joining of the two half bodies is achieved by over-injection of a polymer at the interface between the two parts, the over-injection being performed within the same tool as for the injection of the half bodies. 11. A beverage dispensing apparatus for dispensing a beverage comprising: a container containing a beverage to be dispensed, the container having an opening that is closed with a closure;pressurizing means for increasing the pressure in the interior of the container;a dispensing duct bringing in fluid communication the liquid beverage contained in the container with the exterior, for drawing beverage out of the container, said dispensing duct comprising: a dispensing pipe opening to ambient via a valve, anda pressure reducing channel with an opening connecting in fluid communication the interior of the container with the dispensing pipe;wherein the pressure reducing channel is disposed in a housing made of two half bodies joined together, each body comprising a matching open channel forming the closed pressure reducing channel upon joining, and wherein at least one of the half bodies is an integral part of the closure, and wherein the housing comprises a through channel fluidly connecting the external surface of the first half body with the external surface of the second half body for the injection of propellant gas into the container. 12. A method for producing a pressure reducing channel for reducing the pressure of a liquid flowing through a dispensing duct of a pressure driven beverage dispensing apparatus according to claim 11, said method comprising the following steps: injection moulding two half bodies of a housing, each half body comprising on their inner surface an open channel matching the open channel of the other half;bringing the two half bodies in abutting relationship, with the open channel of one half body vis-à-vis the open channel of the other half body to thus form a closed channel; andjoining the two half bodies to yield a fluid tight channel;wherein at least one of the half bodies is an integral part of a closure of a container containing the beverage to be dispensed, and wherein the housing comprises a through channel fluidly connecting the external surface of the first half body with the external surface of the second half body, for the injection of propellant gas into the container. 13. The method according to claim 12, wherein the joining of the two half bodies is achieved by over-injection of a polymer at the interface between the two parts, the over-injection being performed within the same tool as for the injection of the half bodies. 14. The method according to claim 13, wherein the over-injected polymer is the same as the polymer constituting the half bodies. 15. The dispensing apparatus according to claim 11, wherein the pressure reducing channel is curved and/or has a varying cross-sectional area. 16. The dispensing apparatus according to claim 11, wherein the open channel in one of the two half bodies is provided with walls and the open channel of the other half body is provided with corresponding recesses to ensure alignment of the two half bodies upon joining and to ensure fluid tightness of the closed channel. 17. The dispensing apparatus according to claim 11, wherein components of the dispensing pipe are integral parts of the half bodies. 18. The dispensing apparatus according to claim 11, which is a disposable home beer dispenser. 19. The dispensing apparatus according to claim 11, wherein the housing comprising the channel is made of polypropylene. 20. The dispensing apparatus according to claim 11, wherein the channel comprises at least one sharp bend.
