A dispensing closure for a container includes a base having an annular wall extending circumferentially around a central axis, a top wall coupled to the annular wall, and a controller mount coupled to the top wall. The dispensing closure also includes a product-discharge controller coupled to the controller mount of the base.

A protective cap for a dispenser for discharging liquids, wherein the dispenser has a liquid reservoir and an outlet opening through which the liquid is discharged into a surrounding atmosphere. The protective cap has an inner cap and an outer cap, the inner cap having a ventilation opening for communication between an interior of the protective cap and an external environment. Before use, the outer cap is mounted on the inner cap in a first position with the inner cap and the outer cap in sealing contact with each other and the ventilation opening is separated in an airtight and germproof manner from the environment, and the outer cap is movable relative to the inner cap from the first position to a second position in which the inner and outer caps are out of sealing contact with each other and the ventilation opening communicates with the environment.

The closure system includes an applicator having a closing member (7) which is realized for closing an outlet opening (11) as a result of the restoring force of a resilient restoring element. A blocking element (19) is movable such that, in a blocking position, it retains the closing member (7) in the closed position, but in the open position allows the outlet opening (11) to open.

A discharge head for mixing two media and discharging the mixed liquid, having a dosing chamber, a first inlet, a second inlet, and an outlet through which the mixed liquid is discharged from the dosing chamber. A displacer is movable in an actuation direction between first and second end positions to force the mixed liquid through the outlet. A volume-compensating mechanism has a wall portion which is deflectable between a minimal position in which the volume of the dosing chamber is not enlarged and a maximal position in which the volume of the dosing chamber is enlarged to a maximum extent. Deflection of the wall portion in the direction of the maximal position enables an auxiliary volume to be made available in the dosing chamber through which, with the dosing chamber already filled with the first media, the second media can still be introduced into the dosing chamber.

Disclosed is a container, such as a filled and closed ampoule, comprising at least one plastic material, having a container part for receiving container contents and having ahead part which can be separated from the container part along a separation point and which is integrally connected to the container part before separation, wherein the container has a valve device which, in its closed position, blocks a fluid-conducting connection into the container part and, in its open position, releases this connection.

A dispenser according to an embodiment of the present disclosure includes an outer cap fastened to an inlet of a container capable of increasing internal pressure by an external force and having a nozzle discharging contents contained in the container; a support portion having a plurality of support columns spaced apart from each other around the nozzle in the outer cap; an inertial member guided by the plurality of support columns, moving toward the nozzle when the internal pressure of the container increases, and opening and closing the nozzle; and an elastic member pushing the inertial member away from the nozzle, wherein a first inflow path is formed by a space between the plurality of support columns in a discharge direction of the nozzle, and wherein the first inflow path is configured to allow the contents to press the inertial member when the internal pressure of the container increases.
