A discharger includes a dispensing element and a housing, the housing having a static piston connected to the dispensing element at least in a fluid conducting manner and with the static piston being arranged within the housing. The further includes a container containing a fluid, the container being moveable relative to the static piston and the housing, with the static piston including a piercing tip adapted to pierce a membrane or seal of the container when the container is moved towards the housing.

A fluid dispenser assembly comprising a fluid reservoir (4), a dispenser member (5), and a dispenser orifice (62), the fluid reservoir (4) including a piston (42) that is movable in leaktight sliding contact in a slide cylinder (41) over a maximum stroke defined between a start position that corresponds to a substantially full state of the reservoir, and an end position that corresponds to a substantially empty state of the reservoir, the dispenser assembly being characterized in that it further comprises an RFID tag (40) that is secured to the piston (42).

A set including a pump dispenser for discharging pharmaceutical or cosmetic liquids and an external evaluation unit, which is designed to be exchangeable so that, after the pump dispenser has been emptied, the evaluation unit can be attached to a new pump dispenser. The evaluation unit can be attached to the discharging head of the pump dispenser such that the evaluation unit detects an actuation button and can be partially displaced with same. The evaluation unit can alternatively have a receiving container which is open on at least one side and into which the pump dispenser can be inserted and the force application of which is detected on actuation.

A fluid dispenser having a casing (E) provided with a dispenser head (11); and a refill cartridge (C) that includes a fluid reservoir (R). The refill cartridge (C) is axially insertable into the casing (E) in such a manner as to connect the fluid reservoir (R) to the dispenser head (11). The refill cartridge (C) and the casing (E) are provided with a connection mechanism (17, 253) that connects the refill cartridge (C) in the casing (E) by screw-fastening, so as to bring the fluid reservoir (R) into leaktight contact with the dispenser head (11). The movement, after screw-fastening, of the refill cartridge (C) in the casing (E) towards the dispenser head (11) delivers the fluid to the dispenser head (11).

An aerosol unit for an aerosol dispenser, which aerosol unit comprises an axially oriented body, having a distal inlet part and a proximal outlet part; a carrier member arranged in the body, transversally to the axis between the inlet part and the outlet part; and wherein the carrier member comprises through-holes which place the inlet part in fluid communication with the outlet part, and wherein the carrier member is insert-moulded into the body such that a contact surface between the carrier and the body forms an air-tight seal.

A liquid dispensing system includes at least one container for storing the liquid to be dispensed, the at least one container having a neck defining an fill opening for the liquid. The system includes a liquid dispensing device releasably connectable to the at least one container, an exchangeable cartridge for an additive to be mixed with the stored liquid, where the cartridge is accommodated in the neck, and means for opening the cartridge. The cartridge includes a one-piece hollow body filled with the additive and with a pressurized gas, and the opening means include at least one piercing member arranged to pierce a wall of the hollow body. A method of dispensing a liquid by using the liquid dispensing system, and a cartridge for use in the liquid dispensing system and/or method.

An apparatus for dispensing a fluid from a source of fluid comprises a roller and a tray member. The tray member comprises a pair of spaced walls having a contiguous tapered inner surface for defining an arcuate recess in an outer surface of the tray member, the outer surface tapering to an outer edge of each wall. Roller mounting means includes a pair of resilient spaced arms, each one of the arms spanning between and interconnecting the ends of the spaced wall. The tray member defines a pair ports spaced along a central longitudinal axis of the tray member for providing fluid communication between the source of fluid and the tray member. The roller is rotatably mounted to the spaced arms for receiving fluid from the tray member and applying the fluid onto a surface.

A fluid substance dispensing device includes an external container with a containment element formed of a deformable part and an essentially rigid neck featuring a first flange which abuts with a free end of the external container at one of the mouth thereof, an intermediate element with a cup-shaped part inserted into the neck and fastened to the external container so that the first flange is sandwiched between the free end and the intermediate element, the cup-shaped part including an opening in communication with an internal part of the deformable part, there being—inside the cup-shaped part—a valve element configured for displacement by the body of an airless pump so that, when the body of the pump is absent or in an unused position, the valve element is stably closed, while when the pump body is pushed into a use position, the valve element is stably open.

The present disclosure is directed to an aerosol delivery device and a holder for use with a removable substrate cartridge. In one implementation, the holder includes a first body portion and a second body portion, the first body portion defining a main body and a guide post that defines a receiving chamber extending at least a portion therethrough. The second body portion is configured to rotate about and slide along at least a portion of the guide post to and from a use position, wherein the second body portion is proximate the main body of the first body portion and the substrate cartridge is retained in the receiving chamber, and an open position, wherein the second body portion is rotated relative to and extended away from the main body of the first body portion such that the substrate cartridge can be inserted into or removed from the receiving chamber.

The present disclosure provides a new and innovative container system for mixing and dispensing a solution, such as a cleaning solution, that includes a container, dispenser, and a cartridge. The cartridge includes a reservoir containing a concentrated solution and a snap portion that closes the reservoir. The dispenser includes a sleeve that engages with the snap portion as part of a cartridge release mechanism to release the cartridge's concentrated solution into the container. As the dispenser's cap is tightened to the container, the dispenser's sleeve is forced downwards to engage the cartridge's snap portion and force the snap portion to disengage from the cartridge. The reservoir is therefore opened and its contents exit into the container's interior. As the dispenser's cap is disengaged from the container, the dispenser's sleeve is forced upwards, bringing the snap portion back to the cartridge and closing the reservoir.
