BAG-IN-CONTAINER WITH PREPRESSURIZED SPACE BETWEEN INNER BAG AND OUTER CONTAINER

摘要

Bag-in-container having an inner layer forming a bag filled with a fluid, the bag being separatable from an outer layer forming the container. The bag-in-container has a mouth fluidly connecting the volume defined by the bag to the atmosphere and separated therefrom by a seal. The container further having at least one space vent fluidly connecting the space between inner and outer layers and to the atmosphere. A vent provides a closure to control the gas flow between the space and the atmosphere. The space contains an amount of gas (Vs,i) at a pressure (Pi) insufficient to compress the bag to drive out more than 80% of the fluid contained therein. The present invention also concerns a kit of parts including a bag-in-container and a dispensing appliance.
