Abstract

Soiled and/or contaminated objects often have to be collected before they are specifically disposed of.

According to the invention, in order to prevent blockages in toilets and sewers, a contactlessly operating container (1) is used which has a lid (2) which opens when a hand or an object approaches a proximity detector (50).

The container (1) is suspendable from a supporting housing (12) accommodating the entire control means, the drive and the power supply.

A preferred use of the device is the disposal of sanitary towels (14) which are immersed in a gel (15). The container (1) is periodically replaced by a clean container so that satisfactory hygiene conditions can also be maintained in frequently used toilet areas.

Claims

1. A device for the disposal of soiled and/or contaminated materials, comprising a container closeable by a lid pivotable between a first closed position and a second open position, a drive mechanism having a motor and comprising means for pivoting the cover from the first closed position to the second open position during motor activation and for pivoting the cover from the second open position to the first closed position without motor assist when the motor is deactivated, and a proximity detector coupled to said motor.

2. The device of claim 1, wherein said drive mechanism further comprises a transversely-extending pivoting lever coupled to the motor by a cable connected to a first end of the pivoting lever, the pivoting lever being pivotly mounted at a second end, said pivoting lever second end being coupled through a transmission to a transversely-extending rocker arm having at least one cam at an end thereof for deflecting the pivotable lid into said second open position when the motor is activated.

3. A device according to claim 1, characterised in that the drive mechanism and the proximity detector are mounted on a common supporting housing (12).

4. A device according to claim 1, characterised in that it has a self-contained power supply (63).

5. A device according to claim 1, characterised in that the transmission (32, 32′

) comprises two gearwheels.

6. A device according to claim 5, characterised in that the gearwheels are gearwheel segments (32, 32′

) and are formed in part as bevel gears.

7. A device according to claim 6, characterised in that the gearwheel segments (32, 32′

) are each frictionally connected to the pivoted lever (29) and the rocker arm (8).

8. A device according to claim 3, characterised in that at least one carrying tab (59), from which the container (1) is suspendable, is provided on the supporting housing (12).

9. A device according to claim 8, characterised in that a microswitch (33) is provided in the region of one carrying tab (59) and switches on the power supply when the container (1) has been mounted.
