A fluid dispenser comprising: a casing (E) that is provided with a dispenser head (11); and a refill cartridge (C) that includes a fluid reservoir (R); wherein 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 fluid dispenser being characterized in that the refill cartridge (C) and the casing (E) are provided with connection means (17, 253) for connecting 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) delivering the fluid to the dispenser head (11).

A hydration system is provided. The hydration system includes a container configured to receive and maintain a quantity of liquid, a pump connected to the container, a hose system comprising a plurality of hoses connected to the container and the pump and configured to receive liquid from the container, and an end piece connected to one of the plurality of hoses configured to be used by a user of the hydration system. The pump is configured to circulate liquid through the hose system and container to maintain a relatively similar liquid temperature for all liquid contained in the hose system and container.

A hand cleaner foam dispenser with a first pump arrangement that discharges a first liquid and first air from the atmosphere through a first foam inducing member into a mixing chamber and a second pump arrangement that discharges a second liquid into the mixing chamber, and in which there is a simultaneous discharge of the first liquid, first air and the second liquid from the mixing chamber through an outlet foam inducing member to produce a foamed product delivered onto a person's hand. Preferably, the second pump arrangement may discharge not only the second liquid, but also second air drawn from the atmosphere and discharge the second liquid and the second air through a second foam inducing member into the mixing chamber.

A push-type nozzle assembly includes a cylinder, a check valve, a plunger, a piston, a spring, a rotating member, a locking member, an upper push rod, a suction valve and a push head. When pushing the push head downward, and the outer chamber contact the locking member, the liquid in the cylinder is pushed out. When releasing the push head, the piston moves back by the spring to create a vacuum suction force to suck the liquid left in the nozzle back. When the outer chamber locks with the locking member, the bottom end of the piston rod seals the plunger to seal the cylinder so as to prevent leakage. When the outer chamber is separated from the locking member, the upper push rod seals the suction valve to avoid liquid from leakage. The inlet valve avoids the liquid from being accumulated in the cylinder and the top of the piston.

A liquid dispenser having a liquid reservoir for storing liquid, an elongated nasal applicator, a nozzle plate with a plurality of nozzle openings at a distal end of the nasal applicator through which liquid is discharged, and a conveying device conveying liquid from the liquid reservoir to the nozzle openings. The conveying device has a movable pressure element serving to pressurize the liquid for discharge. The conveying device has an actuating handle, displaceable for the purpose of actuation, from a starting position into an actuated end position. The actuating handle and the pressure element are connected via a spring accumulator loaded by displacement of the actuating handle into the end position and which accumulator subsequently moves the pressure element. The actuating force stored in the accumulator subsequently continues to move the pressure element once actuation has already concluded and thus brings about an ongoing discharge.

An ophthalmic dispenser and method of filling and dispensing fluid stored therein. The dispenser includes a rigid housing defining a fluid-receiving chamber, a flexible bladder receivable within the fluid-receiving chamber, a pump coupled in fluid communication with the fluid-receiving chamber, and a nozzle having a valve defining an annular, axially-extending valve seat, an outlet aperture coupled in fluid communication between the valve seat and the pump, and a flexible valve cover extending about the valve seat and forming an annular, axially-extending interface therebetween. The valve interface is connectable in fluid communication with the outlet aperture, and at least part of the valve cover is movable between (i) a normally closed position with the valve cover engaging the valve seat to close the interface and form a fluid-tight seal therebetween, and (ii) an open position with at least part of the valve cover spaced away from the valve seat in response to pumped fluid flowing through the outlet aperture at a pressure greater than a valve opening pressure to allow the passage of pressurized fluid therebetween. The rigid housing is mountable within a cartridge which, in turn, is mountable within a dispenser housing including an eyelid depressor and a trigger for simultaneously actuating the eyelid depressor and pump.
