Patent

CA 2158838

An openable but sealed container (50) containing a carbonated beverage (52) held under a super-atmospheric pressure includes a hollow insert (10, 12, 70, 80) which contains gas at a super-atmospheric pressure, which has a restricted orifice (22, 79, 84), which floats on the beverage (52), and which includes, orientation means (18, 72, 86) which orientates the insert so that the restricted orifice (22, 79, 84) is submerged in the beverage (52). On opening the container (50), gas from inside the insert (10, 12, 70, 80) is jetted via the restricted orifice (22, 79, 84) into the beverage (52) to generate a close-knit creamy head as it is dispensed. The orientation means (18, 72, 86) is symmetrically arranged relative to a vertical plane containing the restricted orifice (22, 79, 84). Using a floating insert and arranging the orientation means in this way ensures that the restricted orifice (22, 79, 84) is always at the lowermost point of the insert. Thus the risk of the orifice being inadvertently exposed within the headspace in the container is minimised especially during dispensing of the beverage.

Récipient (50) fermé mais cependant ouvrable contenant une boissson gazeuse (52) maintenue à une pression supérieure à la pression atmosphérique. Ce récipient (50) comprend un élément rapporté creux (10, 120, 70, 80) qui renferme du gaz à une pression supérieure à la pression atmosphérique, possède un orifice restreint (22, 79, 84), flotte sur la boisson (52) et comprend un dispositif d'orientation (18, 72, 86) qui oriente l'élément rapporté de sorte que l'orifice restreint (22, 79, 84) soit plongé dans la boisson (52). Lorsqu'on ouvre le récipient (50) le gaz situé dans l'élément rapporté (10, 12, 70,80) est propulsé dans la boisson (52) et sort par l'orifice restreint (22, 79, 84) pour produire un faux-col crémeux et dense au-dessus de la boisson qu'on verse. Le dispositif d'orientation (18, 72, 86) est placé symétriquement par rapport à un plan vertical dans lequel se situe l'orifice restreint (22, 79, 84). Le fait d'utiliser un élément rapporté flottant et de placer le dispositif d'orientation de la sorte permet de s'assurer que l'orifice restreint (22, 79, 84) se situe au niveau le plus bas de l'élément rapporté. Par conséquent le risque que l'orifice soit, par inadvertance, exposé dans l'espace libre du récipient est minimisé, tout particulièrement lorsqu'on verse la boisson.
