Date Apr. 8, 1994A method for filling and closing a package which is initially open on its upper side and has sealable plastic material about the periphery (2) of that side. The package is first conveyed to a location (6), where it is filled. Thereafter, a covering foil sheet (12) is sealed to periphery (2) to cover the open side. The package is brought to a standstill at the filling location (6), and filled through an opening (11) in a strip of the covering foil (7). The strip of covering foil (7) is then moved in a direction (10) lateral to the direction of conveyance (5) of the package, until the open side of package (1) is covered by the foil strip (7). A foil cover piece is then punched from the foil strip (7), leaving a new opening (11), and is sealed to the periphery (2) of the open side of the package (1). The sealed package (1) is then moved from filling location (6) by the conveyor belt (4). The strip of covering foil (7), with the new opening (11), remains stationary until the filling and sealing operation upon the next package (1).
