A fluid dispenser device including a body; a reservoir containing one or two doses of a fluid, the reservoir including a stopper that closes the reservoir in leaktight manner before actuation; a dispenser head that is provided with a dispenser orifice; and dispenser mechanism for dispensing at least a portion of the fluid through the dispenser orifice during actuation. The device further includes a needle having a tip that is adapted to pierce the stopper during actuation, the reservoir being filled with the fluid and being closed with the stopper under a vacuum, so that the residual volume of air present in the reservoir between the fluid and the stopper is substantially zero.

A reusable, refillable airless fluid pump dispenser that is leakproof and designed specifically for travel. To operate the dispenser, the user presses an ergonomic depression on the top of the dispenser to engage the pump and cause a platform within the dispenser to rise, evenly distributing a fluid from the dispenser. The user can twist off the top and remove it from the body of the dispenser, which permits access to the interior of the dispenser to refill or wash as needed. The user may access the platform, raising it or pushing it back down to either adjust the amount of product they would like to fill or to reuse once product has been depleted. The attached outer cap of the top twists to lock, both blocking the nozzle from distributing any product and also preventing the top from depressing and engaging the pump.

A flow device having a body mounted in a sealing manner on a vessel, a spout arranged on an end opposite the vessel, a flow duct having a flow outlet situated on the spout and a flow inlet situated in the fitting portion, an air supply duct having an air inlet is situated on the body and an air outlet. The flow device also has a cap which is translationally moveable with respect to the body, the cap having a first valve and a second valve which cooperate respectively with a first valve seat formed by the flow outlet and a second valve seat which is separate from the first valve seat and is formed by the air inlet. A restoring element exerts a restoring force on the cap so as to keep the valves closed in the absence of an opposing force.

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 fluid dispenser including a body, a chamber coupled to or formed as part of the body and configured to contain a quantity of fluid, and a piston coupled to the body and rotatable within the chamber to different position. The piston is movable relative to the chamber in a first direction along an axis to draw fluid into the chamber, and the piston is movable relative to the chamber in a second direction opposite the first direction to discharge fluid from the chamber. The piston has stroke lengths that are selectable via the different rotational positions of the piston and that are associated with metered quantities of fluid to be drawn into the chamber. An anti-reversal feature is disposed between the piston and the body. The anti-reversal feature inhibits reversal of the piston during movement of the piston in the first direction or the second direction.

A portable chargeable spray bottle is disclosed comprising a body comprising an upper part and a lower part; a spray nozzle assembly equipped on the upper part, and a liquid charging structure placed at the bottom part. It is further comprises an exhaust structure comprising an exhaust hole penetrating the body, whereby exhaust air flow can escape via the exhaust hole to outside the bottle.

A device has a first part with a valve seat and storage chamber, and a second part with a flexible valve cover and actuator. The storage chamber may be formed from a pre-form blow-molded into a flexible pouch defining a variable-volume storage chamber. The flexible valve cover and valve seat form a normally closed valve seam therebetween. The valve cover is movable in response to fluid at an inlet to the seam exceeding a valve opening pressure of the one-way valve between (i) a normally closed position with valve cover and valve seat in contact with each other and defining the normally closed seam, and (ii) a second position with at least a portion of the valve cover spaced away from the valve seat to allow the fluid to pass through the seam. The one-way valve may have anti-spritz features for using the device to dispense a substance, such as to the eye. The device may contain prostaglandins without the device material absorbing the prostaglandins material and/or without the material being adsorbed into the drug.

A spray head for a spray bottle includes a spray mechanism connected to a tube that extends into the spray bottle. The spray mechanism draws fluid from a bottom of the spray bottle, through the tube, to produce a spray of the fluid. A threaded female fitting attaches to a threaded top of the spray bottle. The threaded female, when screwed on to the threaded top of the spray bottle, securely attaches the spray head to the spray bottle. A refill valve, when opened, provides a conduit to refill the spray bottle so that fluid can be poured into the spray bottle without unscrewing the threaded fitting and removing the spray head from the spray bottle. A refill valve cap, when in a shut position, closes the refill valve to prevent spilling of the liquid when the spray bottle is not being refilled.

Rechargeable containers and dispensers, in particular spray bottle dispensers including structures such as strips, pouches, pills, capsules and the like for providing concentrates of chemical agents for charging or recharging the spray bottle dispenser, preferably, individual chemical refill charges containing chemical concentrate are deployed within the spray bottle dispenser to fully contain any inadvertent spillage of chemicals, and to insure a high degree of safety against accidental spills or ingestion. The device is specifically designed for reuse, having a wider opening which is easier to fill, clean and refill without spills, readily accommodates concentrate inserts in any format, minimizes trigger failure, and has a wide base for stability.

A dispenser for dispensing a fluid includes a rigid vial that has a main fluid chamber containing a fluid, and a pump assembly that is in fluid communication with the main fluid chamber and is configured to dispense a predetermined quantity of fluid from the main fluid chamber. A flexible bladder is provided which is located within the main fluid chamber and is configured to expand to fill the ullage created within the main fluid chamber during dispensing of fluid by the pump assembly. The resilient bladder tends to force itself outwardly toward the rigid vial and, in turn, increases the pressure within the main fluid chamber in comparison to the interior of the bladder to thereby prevent the ingress of air or vapors through the bladder or otherwise into the main fluid chamber.
