Liquid dispenser for discharging pharmaceutical liquids, having a housing, an outlet opening and an outlet valve assigned to the outlet opening. The outlet valve includes a pressure chamber arranged upstream of a valve opening and delimited to one side by a valve plate of a valve body. By increasing the pressure in the pressure chamber, the valve can be opened. The pressure chamber has a flat form and has a large surface area in contact with liquid in relation to the volume. At least one portion of the valve plate which is in contact with liquid in the pressure chamber is of a valve plate material produced using metallocenes as catalysts.

Liquid dispenser

A discharge head for a dispenser including a base and an applicator mounted movably thereon. The base is fitted onto a liquid reservoir or is rigidly integrated on a liquid reservoir. The applicator includes a discharge opening through which liquid is released into an environment. The discharge head includes a pump mechanism or a valve mechanism arranged in a liquid channel connecting the liquid reservoir to the discharge opening. The pump mechanism is actuated by displacement of the applicator relative to the base, or the valve mechanism is opened and closed by displacement of the applicator relative to the base. The discharge head includes a cap unit with a cap for covering the discharge opening and a separate securing portion mounted securely on the base or the applicator via a securing mechanism and is designed to secure the cap releasably.

Discharge head for a dispenser for discharging a fluid and dispenser comprising a discharge head of this type and securing section for a discharge head of this type

Sublingual fluid product dispenser

A metering device is provided for metering at least one medium. The metering device includes a medium storage unit and a pumping system connected to the medium storage unit. The medium storage unit or the pumping system has a venting valve which is elastically held in the closed position. The metering device also includes a control member associated with the venting valve in such a way that the control member opens the venting valve as a result of a pumping movement of the pumping system.

Metering device for at least one medium

A discharge device for at least one medium having a medium reservoir, a medium pump and an applicator in which a filler is provided for medium guidance and which has an outlet area for a medium discharge fitted to a slender end area remote from the medium reservoir is known. According to the invention at least two outlets are provided at the outlet area. Use for medium dosing.

Discharge device for at least one medium

A piston plunger ( ) is injection molded from two longitudinal sections ( ) in parallel axial position. The shorter component ( ) is then pivoted around a hinge joint ( ) into position having the same axis as the other component ( ) and tightly connected to the latter using locking means ( ). The shorter component ( ) then forms a nozzle core ( ) and the longer component ( ) forms a piercing tip ( ) for opening a piston membrane ( ).

Dispenser for media and method for producing a dispenser

Dispenser for media

The invention relates to a dispenser, especially a disposable atomizer ( ), with a dispenser unit ( ). Said unit contains a media container ( ) which also forms the pump chamber and which is sealed by a piston-type stopper ( ). When activated, said piston-type stopper is punctured by a hollow needle ( ). The outlet nozzle ( ) surrounds the dispenser unit to a large extent. The dispenser unit ( ) can be introduced into an activating unit ( ). According to one configuration, this activating unit is pin-shaped with a loading chamber ( ). The dispenser unit is held in place by an activating push rod ( ) which can be longitudinally displaced when activated by turning ( ) and is prestressed by a spring ( ). The dispenser is activated by a trigger device ( ). The dispenser unit ( ) can also be changed after use.

Dispenser for flowable media

In order to enable application of a dry i.e. powdery or granulated active substance, said substance is kept apart from a liquid supply in a dispenser. The powder is discharged with the help of said liquid during application. The liquid serves as a carrier for the active substance and is mixed with the liquid to varying degrees prior to discharge. The dispenser ( ) has a liquid chamber ( ) in an ampoule ( ) which is provided with a closure stopper ( ) which can be pierced. The liquid flow which is released upon actuation penetrates into a medium storage chamber ( ), is mixed with the medium ( ) therein and exits via an opened discharge outlet ( ) in the form of a spray mist, jet or drop.

Application method for at least two different media and dispenser therefor

A dispenser ( ) comprises a reservoir ( ) and a plunger pump ( ), the medium inlet ( ) of which pierces a closure ( ) of the reservoir ( ), after which the medium can be discharged metered from the reservoir ( ) by repeated strokes with the pump ( ). Until used the medium thus remains hermetically sealed.

Media dispenser

A dispenser ( ) is provided for unlocking the stroke with two first and second handles ( ) configured separate from the actuator handle ( ) for actuating the pump stroke. For unlocking, the first handle ( ) firstly needs to be actuated in a first release direction ( ). Thereafter only an actuation in a second release direction ( ) is possible with the second handle ( ). It is not until after this second actuation that an unlocked position is attained, which permits implementation of the pump stroke. For the second motion ( ) a restrain drag ( ) is furthermore provided which can only be defeated by increasing the associated actuating force.

In a dispenser, particularly an atomizer, which is used for flowable substances, particularly pharmaceuticals, use is made of a pump, which must be actuated one or more times for priming purposes. Its discharge nozzle ( ) is covered by a protective cap ( ), which is suitable to collect and store the medium, which is discharged during the priming strokes and before the start of the useful strokes. During the priming strokes the protective cap ( ) is secured on the dispenser ( ). This is brought about in that a locking ( ) for the protective cap is only released when the priming strokes have been performed. This can take place by electrical actuation or by material change under the influence of the medium to be discharged. According to a variant the protective cap is not itself locked, but an actuation locking takes place if the protective cap has not been fitted for the priming strokes.

Dispenser and method for discharging media

Discharge apparatus for media

A dispenser ( ) has two remote pressure handles ( ) and lateral gripping recesses ( ) for mutually displacing two units ( ) axially and rotationally. A tear-off web ( ) prevents the two units ( ) from being actuated accidentally. A discharge stud ( ) protrudes beyond the handles ( ). The dispenser ( ) is so small that it may be fully enveloped and covered by one user's hand. Nevertheless reliable actuation for nasal application is assured.
