Abstract

Claims (23)

1. A lubricant dispenser comprising:

a reservoir filled with lubricant and having a downwardly directly floor end face;

an outlet port on the floor end face;

a pump;

a housing holding the pump and having an upwardly directed housing end face juxtaposable with the floor end face of the reservoir;

an intake port on the housing end face, the housing being releasably connectable to the reservoir for connection of the intake port to the outlet port with the end faces closely juxtaposed;

an electric controller on and connected to the pump for, when the housing is connected to the reservoir, conveying lubricant from the outlet port of the reservoir into the intake port of the housing;

an electronic data carrier on the reservoir and carrying information identifying the reservoir;

a first contact array connected to the data carrier of the reservoir, carried on the floor end face, and directed toward the housing end face when the reservoir is connected to the pump housing; and

a second contact array connected to the controller, on the housing end face, and directed toward the reservoir, the first and second arrays being simultaneously mechanically brought together and electrically contacted on mechanical connection of the pump to the reservoir for transfer of the information on the data carrier to the controller.

2. The lubricant dispenser according to claim 1 , wherein the first contact array is pluggable into the second contact array and is thereby electrically contacted, or conversely the second contact array is pluggable into the first contact array and is thereby electrically contacted.

3. The lubricant dispenser according to claim 1 , wherein the data carrier is integrated into the first contact array or is formed with the first contact array.

4. The lubricant dispenser according to claim 3 , wherein the first contact array is an electronic circuit board having or forming the data carrier.

5. The lubricant dispenser according to claim 4 , wherein the second contact array is a printed circuit board jack into which is insertable the printed circuit board of the first contact array as the first contact array, the printed circuit board jack being connected to the controller.

6. The lubricant dispenser according to claim 1 , wherein the electronic data carrier is connectable wirelessly to the electronic controller and can be read out wirelessly by the controller.

7. The lubricant dispenser according to claim 6 , wherein the data carrier has an RFID transponder and the pump or the controller is equipped or connected to an RFID reader.

8. The lubricant dispenser according to claim 1 , wherein the data carrier has a memory in which information can be stored.

9. The lubricant dispenser according to claim 1 , wherein the floor is provided externally with a mechanical retainer in which the data carrier is held mechanically.

10. The lubricant dispenser according to claim 1 , wherein the data carrier is readable by the controller of the pump and information can also be written in the data carrier.

11. The lubricant dispenser according to claim 1 , wherein the reservoir is a collapsible container or has a collapsing inner container that is a cylindrical, flexible cup casing or a concertina-like side wall designed as a bellows, the cup casing or container casing being connected to a rigid base component having or forming the floor.

12. The lubricant dispenser according to claim 1 , wherein the reservoir has an upper top-side container cover that, on emptying of the collapsing container, is lowered toward the floor and the pump, a sensor being provided in or on the pump to detect an approach of the container top wall to the floor in order to detect an empty state.

13. The lubricant dispenser according to claim 12 , further comprising:

a detectable label on the container cover and detectable by the sensor.
