A discharge device is provided with a pressurized product filling and sealing the concentrate and the pressurizing agent P inside the container, and a discharge member discharging the concentrate by breaking through the pressurized product. The discharge member is provided with a valve which becomes a discharge passage of the concentrate, and a cap which covers the valve and is detachably mounted to the pressurized product. The discharge device is provided with a suppressing means (a maintaining mechanism, a movable lid, pressing to the bottom of the recessed part of the projecting part, a part releasing mechanism, a ratchet mechanism, a thin part and a plurality of coupling parts) for suppressing the leakage of the concentrate caused by removing the valve.

The present disclosure relates to foamable dental care compositions and their use thereof for cleaning and caring of the teeth and mouth. With the preparation in foam or aerosol form, the composition can be applied evenly, quickly and efficiently on mouth inserts, cleaning prostheses and other devices used for the simultaneous cleaning of several or all teeth at the same time. The handling is considerably simplified.

Dispensing devices are provided. Such devices utilize a combination of Flair® technology, pre-compression valves and aerosol-like pressurization of the dispensed liquid. An example dispensing device has, for example, a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring. The device further has a piston and a piston chamber which draws liquid from a container and fills the pressure chamber with that liquid as a user operates a trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve. Liquid exiting the piston chamber under pressure enters a central vertical channel which is in fluid communication with both the pressure chamber and a dome valve, with pre-defined opening pressure, provided near the outlet channel at the top of the dispensing head.

Embodiments herein describe a portable device for administering a physiologically active liquid that includes a container for holding the liquid, pressurizing means for applying pressure to the liquid, an atomizer for atomizing the liquid, and an applicator for administering atomized liquid. The atomizer includes at least one nozzle through which liquid can be ejected from the container and an impact element on the nozzle outlet side that is functionally combined with the nozzle. Moreover, the atomizer is configured in such a way that, in a pressure range that can be generated with the pressurizing means, liquid emerging from the nozzle breaks up into droplets prior to striking the impact element.

A pouch reservoir for a pressurized dispenser casing, having a pouch and a dome provided, in its lower part, with a tubular base provided with an external profile for receiving and welding a neck of the pouch and, in its upper part, with a housing for receiving a valve for dispensing a product contained in the pouch. The tubular base and the neck of the pouch welded to the external profile are each provided with a degassing hole at the external profile.

A stem (1) for a two-way valve has a main body (10) outer face that is substantially cylindrical about a main axis, with (i) a first tubular wall (11) closed at its lower end by a first bottom wall (13) and open at its upper end (111), defining a central
channel (113); (ii) a second tubular wall (12), concentric with the first tubular wall (11) and partially surrounding it, closed at its lower end (122) by a second bottom wall (14) and open at its upper end (121), defining an annular channel (123) around the central channel (113), one or more through-holes (124) bringing the inside of the annular channel (123) in contact with the cylindrical outer face of the main
body (10); and (iii) a tubular insert (20) dimensioned so as to be able to be inserted into the annular channel (123).
