  • Patent number: 10619128
    Abstract: A container (1) has a flexible wall (2) and at least one emptying tube (4, 4?, 4?) that projects through a wall aperture (7) into the container interior (3) surrounded by the flexible wall (2). The free end (12) of the emptying tube has an emptying opening (13) that can be set in position vertically to different emptying heights (14). The container (1) is distinguished in that an adapter piece (8), in which the emptying tube (4, 4?, 4?) is held in a longitudinally displaceable manner, is arranged in the wall aperture and in that a portion of the emptying tube (4, 4?, 4?) is surrounded by a flexible sheath (5) that is connected at a first end (11) to the emptying tube (4, 4?, 4?) and at its second end (10), which is remote from the first end (11), to the wall (2) or the adapter piece (8).

  • Patent number: 10233417
    Abstract: A container (2) has flexible walls surrounding a container interior (6). At least one electrical sensor (3, 3?, 3?, 3??, 3??) projects into the container interior (6) and has at least first and second electrically conductive plates (8, 8?, 9, 9?, 9??) for determining the conductivity or impedance of a medium that surrounds the plates (8, 8?, 9, 9?, 9??). The plates (8, 8?, 9, 9?, 9??) are connected via connecting lines (10, 11) to a control and regulating unit (4) outside the container interior (6). At least the first plate (8, 8?) is on a closed free end of a sheathing (5, 5?, 5??) and has a contact area exposed to the surrounding medium. The sheathing (5, 5?, 5??, 17, 17??) is a flexible hose (7) or bellows (19, 19??) through which the electrical connecting line (10, 11) of the plate (8, 8?, 9, 9?, 9??) is routed.
