Abstract:
A dispenser device for liquors, pastes or foams and the like fluid materials comprises a reservoir (10) for fluid material, an outlet (12) for said reservoir and an outlet passage (18) to connect the reservoir outlet with an outlet orifice (19) of the device. Means (21) defining a post-expansion chamber are provided between the reservoir outlet and said outlet orifice to prevent material from escaping from the outlet after use. The post-expansion chamber is configured to increase in size once actuation of the device has stopped.
Abstract:
A pump engine or unit for pump-action fluid dispenser has a fluid storage chamber (16), a final fluid outlet nozzle and a manually actuated pump for delivering fluid from the fluid storage chamber to the outlet under pressure. The engine has a body comprising two parts (48, 50) which define between them the fluid storage chamber and least one chamber (64) of the pump. The fluid storage chamber is defined between opposing wall portions (52, 54) of the two parts of the body and at least one of the opposing wall portions (54) is flexible and is configured to conform closely to the contour of the other of the opposing wall portions (52), at least when the fluid storage chamber is empty.
Abstract:
A manually actuated pump dispenser (210) has a dispenser main body (212, 214) including a first pump chamber (228) for a first fluid. An actuator (216) is mounted to the dispenser main body for movement towards and away from the dispenser main body. A flexible wall member (266) extends between the dispenser main body and the actuator to define a second pump chamber (268) between the dispenser main body and the actuator for a second fluid. The flexible wall member (266) is attached at one end to the actuator or to a part of the dispenser main body and has a distal end (266A) comprising a collar (265) which is mounted to the other of the actuator and a part of the dispenser main body to form a seal therewith. The flexible wall member may be formed integrally with the actuator or the part of the dispenser main body and the collar, for example by using bi-injection techniques. A method of manufacturing the pump dispenser is also disclosed.
Abstract:
This invention relates to pump-action nozzle devices methods of making the same. The nozzle devices of the invention comprises a body which defines an internal chamber having an inlet through which fluid may be drawn into said chamber and an outlet through which fluid present in the chamber may be expelled from the nozzle. The inlet comprises an inlet valve and the outlet comprises an outlet valve. Fluid is dispensed from the dispenser nozzles by applying pressure to an actuator member that engages and resiliently deforms or displaces a portion of the body of the device that defines the chamber, thereby compressing the chamber and actuating the dispensing of fluid. In preferred embodiments, the actuator provides a rigid actuator surface that an operator can apply a pressure to.

Abstract:
This invention relates to pump-action nozzle devices and methods of making the same. The dispenser nozzles of the invention comprises a body which defines two or more internal chambers, both having outlets and at least one of which has an inlet through which fluid may be drawn into said chamber. The inlet comprises an inlet valve and the outlet comprises an outlet valve. Fluid is dispensed from the dispenser nozzles by applying pressure to an actuator member which in turn engages a resiliently deformable/displacable portion of the body of the device that defines the chamber, thereby compressing the chamber and actuating the dispensing of fluid. The additional chamber(s) may contain further liquids or gaseous substance (e.g. air). In preferred embodiments, the actuator is an over cap or a trigger actuator.

Abstract:
The present invention relates to a device that is adapted to be placed inside a container and to permit the continuous dispensing of a liquid stored in a container by enabling the fluid to be drawn from the interior of the container into the device and from the device to the outlet of the container. The device has a body which defines an internal chamber, an inlet through which liquid may be drawn into the chamber, and an outlet through which liquid can be drawing out of the chamber. The inlet of the device is adapted to restrict the access of liquid to the chamber when the device is inverted from a upright position. The present invention also relates to a dip tube and various container assemblies that are likewise adapted to permit the continuous dispensing of a liquid stored in a container.
Abstract:
An apparatus for holding and dispensing metered doses of at least one active composition in a washing machine, a dryer or a dishwasher has at least two separate compartments for respectively receiving and dispensing an active composition and an opening mechanism for the compartments, which is operated by means which are activated by conditions prevailing in the inside of the machine. These conditions prevail solely in the course of a washing, drying or dishwashing cycle. The position of the opening mechanism and/or the compartment(s) after emptying of at least one compartment is changed relative to each other, such that the opening mechanism can then open at least one other compartment, when another activation occurs.
Abstract:
A manual pump fluid dispenser has a base (112) and a dispensing cap (114) with a dispenser outlet (144′) mounted to the base. Insert (116) is mounted between the base and the cap to define at least one pump chamber (122, 123). The insert engages with the base to define an inlet through which a liquid can be drawn into the at least one pump chamber from a liquid source. The insert has a central core (176) and a resiliently flexible upper diaphragm member (184) projecting upwardly and radially outwardly from the core for contact with the cap to define the at least one pump chamber. The insert is movable between an initial resiliently biased configuration in which the volume of the at least one pump chamber (122, 123) is at a maximum and a deformed configuration in which the volume of the at least one pump chamber is at a minimum, in the deformed configuration, the upper diaphragm (184) is at least partially folded down about itself and/or the core. Other aspects of the dispenser are described and claimed.
