Abstract
For a lubricant press (1), a follower piston (13) is proposed that can be inserted into a cartridge (4) and is matched to a closing wall (6) of a cartridge holder (3), such that the follower piston (13) in the used-up cartridge (4) lies against the closing wall (6) in a planar manner.
Claims19
A lubricant press set (26), comprising:
- a lubricant press (1) and a cartridge (4), the lubricant press including a press head (2) with a cartridge receptacle (3), the cartridge receptacle (3) having a closing wall (6) in which a passage (7) leads to a high-pressure chamber (8), a pressing plunger (9) movably arranged in the high-pressure chamber (8), the pressing plunger (9) is in operative connection with a hand lever (11) mounted on the press head (2) and the high-pressure chamber (8) leads to an outlet opening (12);
- a follower piston (13) inserted into the cartridge (4);
- the cartridge (4) includes a cartridge sleeve (27) surrounding a filling volume (5), and the follower piston (13) being movably inserted in the cartridge sleeve (27) to seal off the filling volume (5), a shape of the follower piston (13) is matched to the cartridge (4) such that the filling volume (5) is adapted to be emptied without leaving any residue;
- the follower piston (13) having a top side (15) that faces the closing wall (6) in an operating position, and the top side has a contour that matches a contour of the end wall (6) so that the top side (15) of the follower piston (13) is in planar contact with the closing wall (6) at least in a partial area (16) when a content of the cartridge (4) is used up, and the passage (7) in the closing wall (6) is at least partially arranged outside of the partial area (16).

A method of dispensing lubricant from a cartridge (4) with a lubricant press set (26), comprising:
- providing the lubricant press including a press head (2) with a cartridge receptacle (3), the cartridge receptacle (3) having a closing wall (6) in which a passage (7) leads to a high-pressure chamber (8), a pressing plunger (9) movably arranged in the high-pressure chamber (8), the pressing plunger (9) is in operative connection with a hand lever (11) mounted on the press head (2) and the high-pressure chamber (8) leads to an outlet opening (12);
- providing a follower piston (13) having a shape that matches the cartridge (4) and having a top side (15) that faces the closing wall (6) in an operating position, and the top side has a contour that matches a contour of the end wall (6);
- providing the cartridge (4) including a cartridge sleeve (27) surrounding a filling volume (5) filled with lubricant;
- opening the cartridge (4) at the top and that prior to removal of the lubricant from the cartridge (4);
- inserting the follower piston (13) into the cartridge (4) on an underside in order to close a filling volume inside the cartridge;
- operating the hand lever in order to dispense the lubricant;
- and
- after complete emptying of the lubricant from the cartridge (4) the follower piston (4) is in planar contact with the partial area (16) with the top side (15), and the passage (7) in the closing wall (6) is at least partially arranged outside of the partial area (16).
