System and method for distribution and dispensing of beverages
A method for the distribution and dispensing of beverages utilizes a one-way system including a disposable and freestanding container. The container is blow-molded in one piece from a preform of plastics. The system also includes a tube to be inserted in the container and a closure cap. The container can be filled, distributed to an end user and connected to standard beverage dispensing structure. After use, the empty container is collapsed and discarded.
1. A method for distribution and dispensing of draught beer beverages, comprising the steps of:
providing a preform of plastics;
blow moulding said preform into a container configured for draft beer beverage, said container having a capacity of 10-40 liters, a container wall of the container having a barrier against oxygen and carbon dioxide, said container having a mouth portion, a shoulder portion, a base portion and a body portion extending between the shoulder portion and the base portion, said container being freestanding on a plurality of support legs which form part of the base portion, said container being freestanding without the provision of an outer supporting structure on the plurality of supporting legs, said container comprising a one piece construction and being disposable;
filling said container with a draft beer beverage;
providing the container with a tube structure comprising an elongate tube to be inserted in the container and having an inner conduit for beverage, and a closure element to be connected to the mouth portion of the container, wherein—in use—an inner end of the tube is located adjacent to the base portion of the container and beverage is passed from said inner end, through said conduit and to the closure element for dispensing;
closing the filled container by means of the closure element which is connected to the mouth portion, said closure element acting as a closure cap, wherein said filled and capped container forms a unit for distribution; and
collapsing the container to a smaller volume after the container is substantially empty,
wherein a sidewall thickness of the container body portion is approximately 0.2-0.6 mm.
2. The method of claim 1 , further comprising the step of:
sealing the mouth portion of the container with a tamper and/or dust seal applied to the closure element.
3. The method of claim 1 , further comprising forming the container to withstand a super-atmospheric internal pressure sufficient to dispense the draught beer from the container.
4. The method of claim 1 , wherein the sidewall thickness of the container body portion is approximately 0.35-0.40 mm.
5. The method of claim 1 , further comprising forming the container base portion as a petaloid base.
6. The method of claim 1 , further comprising forming said barrier by a multilayer technique or blend technique.
7. The method of claim 1 , further comprising forming said barrier by application of a coating.
8. The method of claim 1 , further comprising forming said barrier by a metal ion doping.
9. The method of claim 1 , further comprising providing at least a portion of the tube structure with a scavenger or coating.
10. The method of claim 1 , wherein the step of providing the preform of plastics comprises providing the preform of plastics to a producer of draught beer.
11. The method of claim 10 , wherein the step of blow moulding said preform into a container is performed by the beverage producer.
