Patent

CA 2375227

A beer container comprises an inner hollow shell (11) of blow moulded PET to hold beer, an outer hollow shell (12) of moulded high density polyethylene enclosing and supporting the inner shell and a spear structure (13) including a dispenser tube (14) extending from a bottom interior region of the inner shell (11) through to a dispensing outlet (16) at the top of the outer shell (12). Spear structure (13) incorporates valves (25, 26) for supply of pressurising gas into the interior of inner shell (11) and for dispensing beer through the dispensing outlet (16), both valves being formed of PET. When the container has been emptied of beer, the outer shell (12) can readily be separated from the inner shell (11) and spear structure (13) to allow separate recycling of the high density polyethylene material and the PET material.

L'invention concerne un récipient de bière, comportant une coque creuse intérieure (11) constituée de PET moulé par soufflage et destinée à contenir la bière, une coque creuse extérieure (12) de polyéthylène à haute densité moulé renfermant et supportant la coque intérieure, ainsi qu'une structure de lance (13) comprenant un tube de distribution (14) s'étendant d'une région inférieure intérieure de la coque intérieure (11) à un orifice de distribution (16) situé sur la surface supérieure de la coque extérieure (12). La lance (13) comprend des obturateurs (25, 26) pour alimenter l'intérieur de la coque intérieure (11) en gaz de pression et pour distribuer la bière à travers l'orifice de distribution (16). Les deux obturateurs sont constitués de PET. Lorsque le récipient ne contient plus de bière, la coque extérieure (12) peut facilement se séparer de la coque intérieure (11) et de la lance (13) pour permettre un recyclage séparé du polyéthylène à haute densité et du PET.
