Abstract
A liquid dispenser has a liquid reservoir for storing liquid prior to discharge and a nozzle unit through which liquid is discharged in a discharge direction. The liquid dispenser also has an actuating handle actuable in a direction that deviates from the discharge direction in order to convey liquid from the liquid reservoir to the nozzle unit. The liquid dispenser has an inner housing to which the actuating handle is pivotably articulated, and an outer housing displaceable in a translational manner relative to the inner housing between a first end position and a second end position. The actuating handle and the outer housing have cooperating locking positions which prevent actuation of the actuating handle in the first end position and which allow actuation of the actuating handle in the second end position.
Claims24
A liquid dispenser for discharging a pharmaceutical liquid or a liquid containing nicotine or cannabis, the liquid dispenser comprising:
- a liquid reservoir for storing the liquid prior to discharge;
- a nozzle unit through which liquid is dischargeable in a discharge direction;
- an actuating handle actuable in a direction that deviates from the discharge direction to convey liquid from the liquid reservoir to the nozzle unit;
- an inner housing, the actuating handle being pivotably articulated to the inner housing;
- and
- an outer housing displaceable in a translational manner relative to the inner housing between a first end position and a second end position, the actuating handle and the outer housing having cooperating locking portions, the locking portions preventing actuation of the actuating handle in the first end position and allowing an actuation of the actuating handle in the second end position.
A liquid dispenser for discharging a pharmaceutical liquid or a liquid containing nicotine or cannabis, the liquid dispenser comprising:
- a liquid reservoir for storing the liquid prior to discharge;
- a nozzle unit through which liquid is dischargeable in a discharge direction;
- and
- an actuating handle actuable in a direction that deviates from the discharge direction to convey liquid from the liquid reservoir to the nozzle unit,
- wherein the nozzle unit has a nozzle plate including a plurality of nozzle openings configured to generate a spray jet without the influence of air (Rayleigh instability), and the actuating handle is configured as a pivotably movable actuating handle and has an actuating surface of at least 5 cm in length.
