Abstract
The invention is an integrally blow-moulded bag-in-container and preform for making it. The bag-in-container has an inner layer forming the bag and an outer layer forming the container, and a mouth fluidly connecting the volume defined by the bag to the atmosphere. The container further has at least one interface vent fluidly connecting the interface between inner and outer layers to the atmosphere, wherein the at least one vent runs parallel to the interface between inner and outer layers and opens to the atmosphere at a location adjacent to, and oriented coaxially with the bag-in-container's mouth. Processes for manufacturing a preform and a bag-in-container as defined above are defined too.
