Abstract:
The invention is an integrally blow-moulded bag-in-container and preform and a method 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.

Claim (Index 19):
The method according to  claim 17 , wherein the inner and outer layers of the preform are separated over a substantial area of the preform's body by a gap containing air and which is in fluid communication with at least one interface vent, and wherein the blow-moulding operation further comprises the following two stages: feeding a gas in a first stage into the space defined by the inner layer to stretch the preform, whilst the air in the gap separating the preform inner and outer layers is prevented from being evacuated by closing said at least one preform interface vent with a valve located in said fixing means; and opening said valve in a second stage, when the air pressure building up in said gap reaches a preset value, thus allowing evacuation of the air enclosed in the gap.
