    • A packaging container (10, 50) contains a liquid product formed of two or more parts at least one of which is a liquid. The parts are held in the container in separate chambers one of which contains a gas under pressure, e.g. carbon dioxide. The chambers are separated by a wall which is permeable to the gas so that after the container has been closed permeation of the gas through the wall will establish an equilibrium raised pressure throughout the container. When the container is subsequently opened for dispensing the release of pressure from the container causes the wall to be grossly ruptured and allows the parts of the product to be mixed intimately together for dispensing. In the described embodiments an insert (18, 26) in the container holds a gas-free product such as whisky and the container outside the insert holds carbonated water at an elevated pressure of carbon dioxide gas; at least a part of the insert is moulded from a thermoplastic material which is highly permeable to carbon dioxide.
    • 包装容器(10,50)包含由两个或多个部分形成的液体产品,其中至少一个是液体。 这些部件被保持在容器中的分开的室中,其中一个包含一个在压力下的气体。 二氧化碳。 这些室被可渗透气体的壁分开,使得在容器已经闭合之后,气体通过壁的渗透将在整个容器中形成平衡的升高压力。 当容器随后打开用于分配从容器释放压力时,壁会严重破裂,并允许将产品的部分紧密地混合在一起用于分配。 在所描述的实施例中,容器中的插入件(18,26)容纳诸如威士忌的无气体产品,并且在插入件外部的容器在二氧化碳气体的升高的压力下容纳碳酸水; 插入件的至少一部分由对二氧化碳具有高度可渗透性的热塑性材料模制而成。
