The invention proposes a foam dispensing system for a dispenser comprising a reservoir storing cosmetic product, said system comprising a product pump and an air pump, said product pump comprising a variable volume product metering chamber (13) defined at least partly by a deformable element (2), said system comprising at least five valves referred to as a product inlet valve for the product to enter toward the product metering chamber (13), a product outlet valve for the product to exit from the product metering chamber (13), an air inlet valve for the air to enter in an air metering chamber (14) of the air pump, an air outlet valve for the air to exit from the air metering chamber (14), an air return valve for the recovery of the air of the reservoir. The deformable element (2) comprises at least four flaps which are movable between a valve open state and a valve closed state.

A valve for a dispenser pump is carried on a circular post or tube of a pump body. A protruding, sealing flange is formed at one end, while the opposing end includes tapering ribs extend along the inner surface of the hollow, tubular valve. In function, the ribs facilitate the passage of make-up air between the inner surface and the post/tube.

A trigger sprayer is made from a single grade of polymer capable of being reused as post consumer resin. The design allows for upright and inverted actuation. A pre-compression diaphragm ensures that dispensing stroke delivers a complete and uniform amount of fluid.

A container for holding, dispensing and/or storing a preferably liquid medicament preparation is proposed, which comprises an inner space for the medicament preparation and an at least partially multi-layered wall structure defining the inner space, the wall structure comprising a first layer with a first through-opening of less than 40 μm. Alternatively or additionally, the wall structure comprises a second and third layer, a second through-opening being provided in the second layer and the third layer covering or closing off the wall structure.

A packaging for storing and dispensing fluid contents comprises a body defining a reservoir, wherein the body comprises a base with an aperture defined therein, a receptacle configured to store the fluid contents therein is received within the reservoir of the body, and a one-way valve positioned in the aperture. The packaging further comprises an actuator comprising a channel and an opening configured to dispense the fluid contents out of the packaging. An intermediate connecting member comprising a first connection portion configured to engage the actuator, a bellow, a second connection portion configured to engage the body, and a duckbill valve integrally formed thereon extends between the body and the actuator. The duckbill valve is aligned with the channel, and the fluid contents of the receptacle flow out of the duckbill valve, through the channel, and out of the opening upon a user applying an input to the actuator.

This application relates to a fluid dispenser. In one aspect, the dispenser includes a body including an opening and an accommodating space for accommodating fluid, a lid for closing the opening, a pressing unit disposed on a side of the body, and a discharge unit disposed on the side at a position diagonally higher than the pressing unit and configured to discharge a predetermined amount of the fluid from the accommodating space when a pressure is applied to the pressing unit. The dispenser may also include a pump mechanism configured to pump the predetermined amount of the fluid from the accommodating space to the discharge unit when the pressure is applied to the pressing unit, and an air intake formed on a part of the lid and configured to flow air into the accommodating space when the predetermined amount of the fluid is discharged from the accommodating space.

A method is provided for extracting liquid from a liquid dispenser The dispenser includes a liquid container and, connected to the container, a liquid dispensing device is able to take up liquid from the container and convey it along a path as far as at least one liquid outlet so as to dispense this liquid to the outside. The method includes a step of injecting a volume of extraction gas under pressure into the container so as to apply pressure to the liquid of the container in order to cause it to flow along at least part of the device and allow a predetermined quantity of liquid to be extracted from the dispenser.

A dispenser (10) to deliver a liquid medication. The dispenser (10) includes a hollow reservoir body (11) providing an interior that receives the liquid. The body (11) has a threaded neck (13) that receives a cap (58). The cap (58) includes a pump assembly (17) and a nozzle member (29). The pump assembly (17) includes a vent one-way (48) that provides for the delivery of air to the interior of the reservoir (11).

A vented pump includes a pump housing with a fluid retention cavity, a fluid inlet, and at least one vent opening therethrough. A pump dome is secured to the pump housing to form a dome cavity. Movement of the pump dome allows material from the fluid retention cavity to enter the dome cavity through the fluid inlet, and selectively allows ambient air to enter the fluid retention cavity through the at least one vent opening.

A spray dispenser is provided, the spray dispenser comprising a container for holding a liquid to be dispensed and a dispensing assembly for extracting liquid from said container, the dispensing assembly comprising a pressure-relief valve for release of excessive pressure in the container and a filter arranged to permit egress of gas through the filter, inhibit egress of liquid from the container and to inhibit ingress of contaminants into the container through the pressure relief valve. A dispensing assembly for use is a spray dispenser is also provided.
