Abstract: A discharge head for the nasal application of pharmaceutical liquid from a pressure reservoir which has an outlet valve with a valve connector, to which force can be applied counter to a spring force in order to open the outlet valve. The discharge head has a nasal applicator which extends outward from an actuating surface and at the end of which a discharge opening is provided. The discharge opening is connected in a fluid-communicating manner to a hollow tube through an applicator channel of the nasal applicator for connection to the pressure reservoir. The nasal applicator has an inner component connected integrally to the actuating surface and an outer component separate from the inner component and attached to the inner component in a surrounding manner. The discharge opening is provided in the outer component, and the outer component and the inner component together bound the applicator channel.

Abstract: 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.

Abstract: An oral dispenser for discharging a liquid in atomized form. This oral dispenser has a liquid reservoir of variable internal volume for receiving the liquid prior to the discharge, and a spring mechanism. When the spring mechanism is loaded, the liquid in the liquid reservoir is placed lastingly under positive pressure. The oral dispenser moreover has an atomization nozzle unit with at least one nozzle opening, and an outlet channel connecting the liquid reservoir to the atomization nozzle unit. An outlet valve in the outlet channel can adopt an opened state and a closed state. A mouthpiece is provided for inhaling the liquid atomized by the atomization nozzle unit. A refill opening is separate from the atomization nozzle unit and connected to the liquid reservoir, wherein the spring mechanism is loaded by liquid fed through the refill opening into the liquid reservoir.

Abstract: A massage applicator for massaging cream-type fluids into the skin, provided with an end wall with a massage region, on which massage elevations are provided. The end wall is penetrated by at least one outlet channel for the cream-type fluid. The massage applicator is provided with suitable markings in the massage region for measuring the fluid to be used, the applicator is provided with a cover which can be blocked in an open position and/or secured in a closed position, and an assembly of two valves is used in order to secure against unintentional discharge.

Abstract: A vented protective cap for a liquid dispenser, and a venting insert, in particular for such a protective cap. The protective cap has a cap wall which surrounds a cap interior. The cap wall has a venting aperture which is spanned by a flexible sheet-like structure. A boundary region of the sheet-like structure is fixed in an encircling manner to a boundary of the venting aperture. The sheet-like structure consists of at least two layers which bear directly against one another but, at least in a central region of the sheet-like structure, are not connected fixedly to one another.

Abstract: An inhalation device having a reservoir for storing liquid before being discharged, and a discharge head for dispensing the liquid in droplet mist. The discharge head has a nozzle arrangement for generating the droplet mist and housing on which a discharge channel is provided for use as a respiration piece or for attachment of a separate respiration piece. A main axis of extent of the discharge channel encloses an angle of >0° with a central dispensing direction. In alignment with the central dispensing direction of the nozzle arrangement, either an aperture is provided in the housing through which aperture the droplet mist emerges from the discharge head if it is not sucked into the discharge channel by respiration of the user, or a liquid buffer is provided for receiving the droplet mist if it is not sucked into the discharge channel by respiration of the user.

Abstract: Liquid dispenser for discharging pharmaceutical liquid having a discharge head and a cap, the cap body of which has a ventilation opening. The dispenser includes an injection-moulded pull-off portion which, in the delivery state, covers the ventilation opening and is connected to the cap body by a substance-to-substance bond. The pull-off portion, together with a tamper-evident portion, which, with the dispenser in the delivery state, prevents removal of the cap body, is part of a common segment which is detachable from the cap body of the cap. Alternatively, the ventilation opening is provided with a filter membrane for filtering the air which flows through it, and the cap body includes two part-bodies which together form a receiving space for the filter membrane.

Abstract: Two sub-methods are used together to produce a nozzle unit for a liquid dispenser. The methods include adding a nozzle plate into a nozzle channel of a nozzle unit using an assembly tool which elastically expands the nozzle channel. The assembly tool is inserted in the nozzle channel and expands same, thus moving the nozzle plate into its final position where it remains after the assembly tool is removed. The methods also include attaching a filter to a nozzle unit carrier. In a preparation step, a flat filter material is positioned on the end face of the carrier. Only after the filter material is positioned and a connection of the filter material to the end face is established, a separation process is carried out by which the filter material is cut to surround the end face. The filter material positioned on the end face and cut in situ remains.

The at least one locking tooth passes over the counter tooth when the protective cap is rotated relative to the applicator tip in a first direction, and the locking tooth and the counter tooth prevent rotation in a direction opposite the first direction. The protective cap and the applicator tip are adapted to each other such that the discharge opening contacts a lid region of the protective cap after the locking tooth has passed over the counter tooth, and the discharge opening can be closed in a sealed manner by the protective cap. The protective cap is deformable to disengage the locking tooth and the counter tooth.
