摘要:
A metering dispenser for simultaneously or selectively discharging two media, including an outlet opening, a first reservoir for a first medium, a first metering-conveyor device for conveying the first medium from the first reservoir, a second reservoir for a second medium, a second metering-conveyor device for conveying the second medium from the second reservoir, a mixing chamber arranged upstream of the outlet opening and in which the first medium, conveyed by the first metering-conveyor device, and/or second medium, conveyed by the second metering-conveyor device, is stored temporarily, and an output-conveyor device for conveying the medium or media from the mixing chamber to the outlet opening. The first metering-conveyor device has the form of a metering-pump device with a variable-volume metering chamber, an inlet fluidically connected to the first reservoir and having an inlet valve, and an outlet fluidically connected to the mixing chamber and having an outlet valve.

A fluid dispenser pump including a first piston, a second piston, and a dispenser head with a dispenser orifice, for actuating the pump, a shutter arranged upstream from the dispenser orifice, the shutter movable between closed and open positions. The second piston is formed outside a hollow part and is slidable inside the dispenser head. The first piston is slidable inside the hollow part, the hollow part including an axial opening defined by a radial edge through which passes a stem portion of the shutter. The stem portion is between a proximal radial shoulder and a distal radial shoulder of the shutter, the shutter being moved from its closed position to its open position by the radial edge of the hollow part co-operating with the distal radial shoulder, and being moved from its open position to its closed position by the radial edge co-operating with the proximal radial shoulder.

A shut-off system for a dispenser includes a pinch member that moves relative to a guide and which is normally biased against a flexible outlet tube that is disposed therebetween. The flexible outlet tube that carries material, such as soap, supplied from a pump to an outlet nozzle. The pump and the pinch member are in operative engagement with an actuator, such that when the actuator is not engaged, the pinch member closes the outlet tube to prevent residual material retained in the outlet tube from flowing or drooling out of the outlet nozzle. Correspondingly, when the actuator is engaged, the pump is compressed, and the pinch member is moved away from the outlet tube, allowing the material to be pumped through the outlet tube and dispensed from the outlet nozzle.

A dispenser has a body with a variable-volume storage chamber for storing product. A compression chamber is in fluid communication with the storage chamber for receiving substance therefrom. A one-way valve of the dispenser includes valve seat and flexible valve cover seated on the valve seat and defining a normally-closed seam therebetween forming a fluid-tight seal between the valve cover and valve seat. The flexible valve cover is movable relative to the valve seat to allow the passage of substance through the seam and out of the dispenser. A manually-engageable actuator connected to the dispensing portion is movable between first and second positions to dispense substance within the compression chamber out of the dispenser.

A fluid application system includes a diluent reservoir, a chemical container, a sprayer housing, a manifold located in the sprayer housing, and a pump assembly in fluid communication with an outlet of the manifold. The manifold includes a diluent inlet in fluid communication with the diluent reservoir, a chemical inlet in fluid communication with the container, a mixing chamber in fluid communication with the diluent inlet and the chemical inlet and the outlet of the manifold. The pump assembly draws a mixture of the chemical and the diluent from the manifold and sprays the mixture of the chemical and the diluent from the nozzle.

A container includes a nozzle having rubber elasticity in a constriction part, and a lever for nipping the nozzle indirectly. The nozzle has a storage part, a base, and a valve. The storage part is provided in the constriction part, and is intercepted with the main body by contacting inner walls at the communicating part when the nozzle is nipped and flattened by the lever. The valve is opened when the internal pressure of the storage part exceeds predetermined pressure while operated state and spouts liquid in the storage part. The constriction part expands by being nipped with the lever until the internal pressure of the storage part reaches to predetermined pressure. Liquid in the storage part is jetted since the constriction part shrinks by the rubber elasticity when the valve is released.
摘要:
A dispensing apparatus for containing a pressurized composition, said dispensing apparatus comprising: a reservoir for containing a composition; an actuator head comprising a side wall having an interior surface, said actuator head forming a dispensing orifice through said side wall; a displaceable flow conduit comprising a proximal end in fluid communication with said reservoir and a distal end forming a flow conduit orifice, said distal end being movably engaged with said interior surface of said actuator head; and an intermediate member interposed between said interior surface and said distal end and forming an aperture; and wherein said displaceable flow conduit is biased to an at-rest position and can be movably actuated to at least partially engage said intermediate member in a dispense position, thereby at least partially aligning said dispensing orifice with said flow conduit orifice.

A foamer pump for dispensing foam has a simple construction and utilizes a single piston to reduce the volume of both a fluid chamber and an air chamber. A portion of the actuating mechanism helps to unseat a check valve at the outlet of the fluid chamber. The foamer pump has a fluid chamber, and an outlet of the fluid chamber is connected to a mixing chamber. An air chamber has an air channel that connects the air chamber to ambient air in a first position and to the mixing chamber in a second position. A piston causes the volume of air chamber and the liquid chamber each to be reduced, forcing air from the air chamber and foamable fluid from the liquid chamber into the mixing chamber where they blend to form an air/liquid mixture.

The application describes small hand-held dispensers suitable for use with creamy flowable products such as cosmetics. The dispensers are of a kind having a top plate (4) with a dished pick-up surface (42), and a product discharge opening (43) opening into the pick-up area (42). Specific proposals include positioning the pick-up surface (42) and an actuator (8) side-by-side on the top plate. The actuator (8) operates a pump (6), desirably positioned beneath the actuator and offset from the pick-up surface (42). A corresponding transverse outlet conduit (69) may be provided. The container (1) may be plastics or a metal container. Embodiments using plastic pump springs and resiliently deformable pump chamber walls are also described. Also, embodiments in which actuation is by tilting of the top plate in its entirety, the pick-up area then optionally being central.
