CA 2158837

An insert (10, 12) for use in providing a creamy head on a carbonated beverage dispensed from a beverage container (50) comprises a restricted orifice (20) for providing communication between its inside and outside, and a pressurised gas contained inside. The restricted orifice (20) is separated from the pressurised gas by a closure (22) which is arranged to be permanently and irreversibly opened on being subjected to a temperature above a predetermined threshold, or on being subjected to a pressure difference in which the pressure outside the insert (10, 12) exceeds that within. This enables the insert to be pre-pressurised and completely closed and stable during insertion into the container (50) and during filling. Then the closure (22) is permanently and irreversibly opened during a subsequent pasteurisation step to ensure that all of the gas is vented from the insert (10, 12) on opening the container (50).

Elément rapporté (10, 12) utilisé pour produire un faux-col crémeux au-dessus d'une boisson gazeuse versé d'un récipient (50) contenant de la boisson, comprenant un orifice restreint (20) qui assure la communication entre l'intérieur et l'extérieur, et un gaz sous pression enfermé à l'intérieur. L'orifice restreint (20) est séparé du gaz sous pression par un dispositif de fermeture (22) qui est prévu pour être ouvert de manière permanente et irréversible lorsqu'il est soumis à une température supérieure à un seuil prédéterminé ou lorsqu'il est soumis à une différence de pression telle que la pression à l'extérieur de l'élément rapporté (10, 12) est supérieure à sa pression interne. Ceci permet à l'élément rapporté d'être préalablement mis sous pression et d'être entièrement fermé et totalement stable lorsqu'on l'introduit dans le récipient (50) et lorsqu'on remplit ce dernier. Le dispostif de fermeture (22) s'ouvre ensuite de manière permanente et irréversible pendant une étape de pasteurisation subséquence afin que la totalité du gaz soit expulsée de l'élément rapporté (10, 12) lorsqu'on ouvre le récipient (50).
