The connecting head (10) is tapered toward the free end (13), wherein the outer surface has at least one first curved outer surface section (14, 14a, b), which is inclined toward the longitudinal axis (3) of the cartridge (1), and a second outer surface section (16, 16a, b) opposite from the first outer surface section (14, 14a, b). The inlet and outlet openings (20, 22, 24) are located in the first and/or the second outer surface sections (14a, b, 16a, b). The connecting head (10) is inserted in the holder (50) in the axial direction, wherein the inside surface of the holder (50) has first and second inside surface sections (54, 54a, b, 56, 56a, b) that complement at least the first and second outside surface sections (14a, b, 16a, b).
The invention relates to a device for the treatment of drinking water, having a housing (1) in the form of a stand, a mechanical filter unit (2, 3) for removing foreign bodies from the untreated water, a hand drive (4) for a gear pump (7) which supplies water pressure for operating a reverse osmosis unit (5), and a water tank (6) which receives the treated water.

LATTICE STRUCTURE, USE OF THE LATTICE STRUCTURE AND VESSEL WITH LATTICE STRUCTURE
A lattice structure (1) for the passage of a first medium against a second medium, comprising transverse elements (20) and longitudinal elements (10), lattice openings (4) having an internal width of ≤ 300 쎽m being arranged between the transverse elements (20) and longitudinal elements (10) is described. On at least one side (2, 3) of the lattice structure (1), the transverse elements (20) and/or the longitudinal elements (10) have a rib arrangement (8, 8a, 8b) composed of ribs (31, 32, 41, 42) which project at right angles to the lattice plane (6), at least one first group (30) and a second group (40) of ribs (31, 32, 41, 42) being provided, which differ at least by their rib heights H1, H2 where H1 ᡶ H2. A vessel (50) with at least one water inlet window (54) and at least one air exit window (55) is also described, both windows being provided with the lattice structures (1).
