PCT No. PCT/NO96/00291 Sec. 371 Date Jul. 17, 1998 Sec. 102(e) Date Jul. 17, 1998 PCT Filed Dec. 18, 1996 PCT Pub. No. WO97/22542 PCT Pub. Date Jun. 26, 1997A device in the form of a funnel (1) and comprising a holder (2) and a folded bag (36), for filling a container (8) such as an oil barrel or a standard container such as a type IBC, in such a manner that the bag forms an insulated lining between the product, e.g. oil, with which the container has to be filled, and the actual container. The device further comprises a lining (24) for mounting in the container's filling opening (10), and in the lining there is mounted a bottom member (22) which is surrounded by the bottom of the bag (36), the latter and the bottom member being pushed into the bag's main part from the top and down through the bag's opening (23). When the container is filled the funnel (1) is first screwed by means of the lining (24) into the filling opening (10), and a supply pipe (14) with enclosed push rod (18) is pushed down through the holder (2), passing the bag (36) in an evacuated state down to the bottom of the container. Special design of the bag (36), axial slots (16) at the bottom of the supply pipe (14) and guide elements (46, 46') ensure that the bag is expanded in the correct manner during filling. At the bottom of the push rod (18) there is a closing/push piston (20) which closes the supply pipe during the final phase of filling. After filling the lining (24) is kept screwed into the container and is closed by a lid (19), until the container is empty and a new funnel has to be mounted thereon.
