A pump assembly for generating and dispensing of particles of a solid material with or without dispensing of a fluid. The pump assembly preferably includes a fluid pump which in a cycle of operation draws the fluid through a fluid inlet and dispenses the fluid out a fluid outlet. The pump assembly carries a block of the solid material coalesced together and a rasp member, which during the cycle of operation, moves relative the rasp in engagement with the block whereby the rasp member disengages particles of the solid material from the block which particles drop under gravity downwardly adjacent the fluid outlet, for example, onto a user's hand as in the case that the fluid is a hand cleaning fluid and the solid is a solid soap.

A multi reservoir dispenser includes a first reservoir for holding a first fluid and a second reservoir for holding a second fluid. The dispenser further includes a pump mechanism that includes a pivotable trigger and a first plunger cavity that is disposed along the first flow path for receiving the first fluid and a second plunger cavity for receiving the second fluid. The pump mechanism also includes a first plunger that is disposed and movable within the first plunger cavity and a second plunger that is disposed and movable within the second plunger cavity. A selectable actuator is movable between: (a) a first position in which only the first plunger of the pump mechanism is actuated for discharging only the first fluid through a first orifice of a nozzle by causing the first fluid to flow along a first flow path; and (b) a second position in which only the second plunger of the pump mechanism is actuated for discharging only the second fluid through a second orifice of the nozzle by causing the second fluid to flow along a second flow path.

A device for dispensing fluid products includes one or more containers, each storing one fluid product, a unique pump provided with a dosage chamber enclosing a dose of mixture of the fluid products, and including an actuating member, and a manifold associating the pump to the containers for dispensing the fluid products. The manifold includes one or more hollow tubes each extending into a container and forming a channel for the flow of the fluid product from the container towards the pump. As well, the tubes of the manifold are rigid and at least one tube of the manifold includes means for regulating the volumetric ratio of the fluid product flow, these regulating means being integrated inside the rigid tube.

A two-component piston for a cartridge includes a piston cover and a piston body. The piston cover has a radially extending attachment portion, a rear side and a front side. The piston body includes a front side and a rear side. The rear side of the piston cover is arranged adjacent to at least a part of the front side of the piston body and includes a valve member configured and arranged to be received within the piston body and to extend into the piston body towards the rear side of the piston body. The piston cover moves relative to the piston body upon actuation of the valve member, and the piston cover is non-releasably connected to the piston body by a part of the piston body being overmolded to the radially extending portion of the attachment portion of the piston cover.

A trigger head for a dispensing device for at least two substances including a pumping system to compress the substances separately and simultaneously before dispensing.

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 container for fluid products, particularly pharmaceutical, cosmetic, medical products or the like includes an hollow body divided into: a first tank containing a first fluid substance and communicating with a first dispensing hole of the first fluid substance; a second tank containing a second fluid substance and communicating with a second dispensing hole of the second fluid substance; a neck associated with the hollow body and on which are formed the first dispensing hole and the second dispensing hole; a selector element associated with the neck by interposition of rotation means able to rotate the selector element around an axis of rotation, and the selector element includes an outlet channel able to dispense selectively, due to the rotation of the selector element, the first fluid substance or the second fluid substance.

Systems and apparatuses include a prime mover, a pump driven by the prime mover, and a sprayer receiving a flow of water from the pump. The sprayer includes a sprayer housing, a first fluid reservoir coupled to the sprayer housing, a second fluid reservoir coupled to the sprayer housing, a chemical selector coupled to the sprayer housing and movable between a first chemical position and a second chemical position, a high pressure selector coupled to the sprayer housing and movable between a high pressure position and a chemical spray position, and a nozzle assembly in communication with the chemical selector and the high pressure selector.
