Abstract:
A dispenser head for dispensing a liquid or pasty medium, which dispenser head is fastenable to a container storing the medium, including an intermediate element with a receiving opening for the container and an actuating handle which is coupled displaceably in an actuating direction to the intermediate element, wherein the intermediate element and/or the actuating handle have/has at least one releasable connecting element providing a retaining force between the intermediate element and the actuating handle, which retaining force is opposed to a relative movement between the intermediate element and the actuating handle.
Abstract:
A dispenser for discharging liquids with a liquid reservoir for accommodating the liquid prior to being discharged, and a liquid outlet passage which leads to a liquid outlet opening through which the liquid reservoir communicates with a surrounding atmosphere. In a use position, the liquid outlet opening is arranged below the liquid reservoir such that the liquid flows on account of the weight thereof in the direction of the liquid outlet opening, and the liquid outlet passage in the use position does not simultaneously permit air to enter the liquid reservoir and liquid to exit into the surrounding atmosphere. In order to reduce the internal volume of the dispenser and therefore to effect a discharge of liquid, a slide is pushed manually in an actuating direction from a stroke starting position into a stroke end position.
Abstract:
A discharge device for liquids, which includes a pump chamber that is limited by two valves, which in each case include a valve body section and a valve seat. Channels are arranged concentrically and a fixing region of a valve body of one or of both valves is attached to an intermediate wall between the channels.
Abstract:
Liquid dispensers with a housing, a reservoir for receiving liquid prior to discharge, a discharge opening, and a conveyor device for conveying liquid from the reservoir to the discharge opening.The conveyor device includes a metering chamber with a cylindrical wall, and a piston adapted to the cylindrical wall to allow a sliding movement thereon. The metering chamber and the piston are displaced relative to each other between starting and end positions. An outlet side of the metering chamber is adjoined by an outlet chamber, and an inlet side of the metering chamber is adjoined by an inlet chamber. The piston is arranged in the inlet chamber when in the starting position and in the outlet chamber when in the end position. During the transition from the starting position to the end position, the liquid in the metering chamber is pressurized for discharge through the discharge opening.

Abstract:
A discharge device for discharging pharmaceutical liquids, with a housing, a liquid reservoir with a receiving space for storing the pharmaceutical liquid, and a discharge opening which is provided on the housing and which connects the receiving space to an environment and serves to dispense the pharmaceutical liquid. A pretensioned spring mechanism is provided, by means of which liquid in the receiving space of the liquid reservoir is subjected to pressure and which, in the assembled state of the discharge device, is not accessible for input of energy.
Abstract:
A discharger for a flowable medium, having a pumping device with a pumping chamber which is closed off on one side by a longitudinally movable piston, is provided.The pumping chamber on the piston side is hermetically sealed against an environmental atmosphere outside the discharger by a gas-impermeable and at least partially flexible diaphragm, and the diaphragm, in its marginal region, is fixedly connected to a housing of the discharger.The discharger is used for high sealing requirements against the ingress of impurities.
Abstract:
A discharging device for liquids.The invention relates to a discharging device for liquids, more particularly for pharmaceutical liquids, comprising a delivery device (10), a liquid storage receptical (20) communicating with an input (10a) of the delivery device for storage of the liquid (30), and a discharge orifice (12) which communicates with an outlet (10b) of said delivery device,and the liquid storage receptical (20) is at least in part in the form of a dimensionally flexible liquid-containing bag (20) and the liquid storage receptical (20) is disposed in a buffer chamber of constant volume (42).To prevent air from escaping from the buffer chamber (42), provision is made for the buffer chamber to be sealed by a protective housing from the environment (1) in a gas-tight manner, for the buffer chamber to communicate with the environment through at least one capillary passageway for the purpose of pressure compensation, or for the buffer chamber (42) to communicate with the environment (1) via a balancing passageway for the purpose of pressure compensation, while a valve (70) which opens in dependence on the pressure differential is disposed in this balancing passageway.
Abstract:
The invention relates to a discharging device (10) comprising an external housing (20), a discharge port (66), a liquid container (80), an outlet passage (58, 56, 70, 74), by means of which the liquid container (80) communicates with the discharge port (66), and a manual actuator (82) capable of being moved relatively to the external housing (20), and the manual actuator (82) is mechanically coupled to the liquid container (80) such that displacement of the manual actuator (82) causes a reduction in volume of the liquid container (80)According to the invention, there is assigned to the outlet passage (58, 56, 70, 74) a valve unit (54, 72), which, when open, permits communication between the liquid container (80) and the discharge port (66) and, when closed, blocks communication between the liquid container (88) and the discharge port (66), and the valve unit (54, 72) has a valve manipulator (68) which is accessible from outside and by means of which the valve unit (54, 72) can be transferred, from outside, from the open state to the closed state.The use thereof, more particularly as a non-returnable dispenser for discharging a single batch of a product.
