A dispenser for discharging pharmaceutical liquids, in particular in the form of individual drops. Such a dispenser is designed as a side-actuation dispenser with an actuation button on the dispenser in the region of a lateral surface of the housing and has a liquid store, a pump device with a pump chamber which has a variable volume, and a dispensing opening for dispensing the liquid. The actuation button is a spring-loaded toggle switch, the volume of the liquid channel is reduced using an insert, and a special housing design is provided for the purpose of adapting the dispenser to the customer's needs.

An apparatus (100) for metered dispensing of a liquid from a container (3) and a spray applicator having the apparatus (100). The apparatus (100) comprises a base body (5) and a nozzle body (16) having an outlet nozzle. The nozzle body (16) is mounted so as to be displaceable relative to the base body (5) from a dispensing to a clamping position. The apparatus (100) comprises a reset spring (14) for moving the nozzle body (16) from the clamping to the dispensing position. The nozzle body (16) and the valve body form a burst chamber (19). By pressure on the trigger mechanism (26), the locking of the valve body (10) is triggered and the spray burst spring (7) presses the valve body (10) in the nozzle direction. A non-return valve is arranged upstream in the valve body. The spray burst chamber is connected to the outlet nozzle.

A liquid dispenser having a liquid reservoir and a discharge head secured thereto, an outlet valve with a pressure chamber and an opposite valve chamber. The liquid reservoir and the valve chamber are each connected at least in phases to a surrounding atmosphere by a ventilation channel. The two channels provided for this purpose, the reservoir ventilation channel and the valve ventilation channel, are separate channels with separate inlets on an outer face of the discharge head.

A dispenser for dispensing liquid or pasty materials has a head part with a dispenser opening. The dispenser opening is formed by lip sections which lie directly on top of each other. A lip section for opening the dispenser opening can be lifted from the other lip section by means of a lifting part that engages on the lip section. The lifting part acts on the lip section with a loading direction that runs transversely to a dispensing direction of the material.

A trigger type liquid ejector includes an ejector body and nozzle, the ejector body includes a vertical supply pipe, ejection barrel, trigger, piston, and cylinder, a recovery passage brings the cylinder in communication with the vertical supply pipe via a space between a piston body and a piston guide of the cylinder formed in the ejector body, the vertical supply pipe has a lower inner tube part where the recovery passage opens, the trigger type liquid ejector further includes an upright and inverted posture adaptor attached into the lower inner tube part where communication between the recovery passage and an inside of a container body is blocked, and a communication passage brings the recovery passage in communication with the inside of the container body forms between an outer circumferential surface of the upright and inverted posture adaptor and an inner circumferential surface of the lower inner tube part.

Spray dispenser for nasal drugs includes a non-pressurized bottle for storing medical fluids in particular of drugs and other sterile fluids, a mounting body mounted to the top of the bottle and an actuating body, wherein the bottle, the mounting body and the actuating body are aligned along a longitudinal axis, and wherein the actuating body is slideably attached to the mounting body along the longitudinal axis and movable between an actuating position and a non-actuating position, wherein the spray dispenser includes an applicator nozzle and an actuating section for moving the actuating body into the actuating position, characterized in that the applicator nozzle has a nozzle axis which is inclined with respect to the longitudinal axis, the applicator nozzle facing away from the actuating section.

A discharge device for a liquid medium includes a storage container for receiving a medium, a discharge head which can be secured on the storage container and comprises a discharge opening for discharging the medium out of the storage container, an outlet valve which is paired with the discharge opening and comprises a pretensioned valve element that delimits a valve pre-chamber by means of a pressure application surface formed on a membrane. The pressure application surface has a stationary clamping region on the outside, and a pressure equalization channel which opens into the storage container and comprises a filter assembly that operates microbiologically and is inserted into the pressure equalization channel. The pressure equalization channel is separated from a medium path from the storage container to the discharge opening via the valve pre-chamber, and the pressure application surface has a cap-like edge protrusion as a clamping region which can be placed on a plate edge of the inner component of the discharge head on the inside. The plate edge has a stop that extends outward radially and forms a support surface for the edge protrusion while being spaced from the pressure application surface by a head surface of the plate edge.

Disclosed is a pump head with a specially configured elastic valve which enables secure closure of the pump head. It is ensured by the valve that complete emptying and, at the same time, secure closing of the pump head is ensured so that no residues of fluid to be metered remain in the storage state of the pump head. In addition, the present invention relates to a metering device which can be configured for example as squeeze bottle, as non-airless system or as airless system, the metering device comprising a pump head according to the invention.

The present invention relates to a modular closure device (7) for a device for dispensing a product, comprising: —an outlet nozzle (9) comprising: an outlet orifice (15) at the front, a rear opening, a product intake orifice, —top valve comprising a shut-off member (17) that closes of the outlet orifice, a deformable membrane (22) that seals the rear opening closed, designed so that a depression inside the nozzle forces the shut-off member toward its closed position, and a rigid frame extending between the outlet orifice and the membrane; —a bell housing having an end wall and base opening opposite this end wall, the edges of the base opening being fixed to the nozzle, the membrane sealing the base opening closed. The invention also relates to a dispensing device comprising this closure device.

The invention relates to a pump head (I) with a specially designed flexible valve (20) which securely connects the pump head. The valve ensures the pump head is securely closed. The invention also relates to a metering device which can be designed, for example as a squeeze bottle, as a non-airless system or as an airless-system. Said metering device comprises the claimed pump head.
