Patent ID: 7959430

Claim:
A device for producing a container having an outer rigid container and an inner deformable pouch, a space between outer container and inner deformable pouch, and an opening to the container, comprising: means for inserting a plug into the container opening to seal the opening, a pressure sensor configured for insertion into the inner pouch, at least one outer container wall penetrating tool having a channel in a head of the tool, a pressure medium source connected to the channel in the head of said tool and the inner pouch, at least one drilling station carrying said tool, said drilling station having a control drive for advancing and retracting said penetrating tool, and a control device operatively connected to said pressure sensor, said pressure medium source and said drilling station for advancing the tool to penetrate a wall of the outer container and introduce a pressure medium into the space between the outer container and the inner pouch after penetration of the wall of the outer container, stopping the advance movement of the tool when a predetermined first pressure threshold value has been reached in the inner pouch, continuing to introduce pressure medium into the space between the outer container and the inner pouch until a predetermined second threshold pressure value has been reached in the inner pouch, retracting said tool from the container to relieve pressure in the space between the outer container and the inner pouch, and introducing a pressure medium into the inner pouch to place the inner pouch, which has detached from the rigid container wall, against the rigid container wall.
