MANUAL PUMP DISPENSER AND A METHOD OF MANUFACTURING THE SAME
A manual pump dispenser has a body having an annular wall portion (467) and an insert (416) having a central core (416a) and a closure member (460) extending radially from the core for cooperation with the annular wall portion to define a pump chamber (105). An inlet arrangement for the pump chamber comprises a pair of axially spaced sealing portions (462, 464) on an outer circumferential region of the closure member that define an inlet chamber (463) and a fluid passageway (461) within the insert fluidly connecting the inlet chamber with a fluid source. A downstream one (462) of the spaced sealing portions is operative to allow fluid to flow into the pump chamber from the inlet chamber but to prevent fluid from flowing in the opposite direction.
A precompression valve has a body(314) defining a fluid inlet, a fluid outlet and a fluid passage (373) from the inlet to the outlet. A resiliently deformable valve member (372) is located in the passage. The valve member has a resiliently deformable body (372a) smaller than the bore and a resiliently deformable sealing skirt (388) mounted to part of the body to engage with a sealing surface of the passage to prevent fluid flowing through the passage when the body portion and sealing skirt are both in initial resiliently biased configurations. The valve member body (372a) deforms when subjected to a force causing the sealing skirt (388) deform or move to open a flow path through the valve. During at least part of the deformation of the body, the sealing skirt (388) is deformed and held in the sealing position by the pressure of the fluid acting upon it. The valve is arranged so that when a minimum fluid pressure level is reached, the sealing skirt (388) is moved sufficiently to open a fluid flow path through the valve. As the pressure differential across the sealing skirt equalises, it is then able to at least partially reform to its original shape increasing the area of the fluid flow path.
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.
A pump dispenser (20) for mounting to a liquid container comprises a cylindrical type pump arrangement of the type having a mounting member (25) for mounting the dispenser to the container, a generally cylindrical body (23) located within the mounting member for projection into the container, a turret collar (24) for positioning the body within the mounting member, an elongate piston (22) movably mounted within the body, a seal member (26) operative between the piston and an inner surface of the body to define a liquid pump chamber (43) within the body and an actuator (21) mounted to, or operatively connected with, the piston. The dispenser is adapted to provide an air pump chamber (50) at least partially within the actuator and an outlet passageway arrangement of the dispenser includes at least one constricted orifice (36) through which liquid from the liquid pump chamber is passed.
A pump dispenser (20) has a pump arrangement for mounting to a reservoir (not shown) for holding a liquid to be dispensed. The pump arrangement includes a liquid pump chamber (43) for pumping liquid from the reservoir, an air pump chamber (50) for pumping air and a common actuator (21) to simultaneously actuate the liquid pump and the air pump. An outlet fluid passageway arrangement (31, 33, 34, 35, and 52) fluidly connects the liquid pump chamber and the air pump chamber with an outlet (36). The dispenser has an outlet valve arrangement (26, 26, 53) for controlling release of liquid from the liquid pump chamber and air from the air pump chamber during a dispensing cycle. The dispenser is configured such that the ratio of air to liquid dispensed varies over the course of each dispensing cycle. Preferably, the ratio of air to liquid is lower during a main dispensing phase, when the pressure of the liquid is at its highest, than during at least one of an initial phase and an end phase during which the pressure of the liquid is lower than during the main phase.
A manually actuated pump dispenser for dispensing a mixture of air and at least one other fluid, the dispenser comprising a final outlet, a cylinder (722), a plunger assembly (714) slidably received in the cylinder to define within the cylinder a main pump chamber (724) of variable volume, a final outlet including an outlet valve arrangement, an air inlet for admitting ambient air into the main pump chamber, wherein the plunger assembly (714) comprises a plunger body and a traveller member (752) mounted to the plunger body within the cylinder, at least part of the traveller member being movable relative to the plunger body to define with the plunger body a fluid dosing chamber (772) of variable volume, a fluid dosing chamber inlet connected to a fluid source and a fluid dosing chamber outlet through which the fluid can be dispensed together with pressurised air from the main pump chamber.
A manual pump action dispenser for dispensing at least one liquid from a container, the dispenser comprising a base and a cap (114) having an outlet (144) for the liquid, the base being mountable to or forming part of a container and the cap (114) being mountable to the base for movement relative to the base between a rest position and an actuated position, the dispenser further comprising a flexible insert (116) locatable between the base and the cap (114) to define a first pump chamber (122) for dispensing said at least one liquid, the insert being adapted to engage with the base to define an inlet through which said at least one liquid to be dispensed can enter the first pump chamber, the dispenser further comprising an inlet valve operable to enable liquid to enter the first pump chamber (122) through the inlet and an outlet valve arrangement operable to control the release of liquid from the first pump chamber through the outlet, in which the insert also defines a second pump chamber (123) for dispensing a second fluid.
A pressurised dispenser valve (110) has a valve housing (111) with at least one fluid inlet (127, 128) though which a fluid present in an associated dispenser may pass to enter the valve housing. The at least one fluid inlet is formed at least partly by, or in a resiliency deformable portion (124, 125) of the valve housing. The deformable portion (124, 125) is arranged such that, in use when the valve is opened, it deforms from an initial resiliency biased configuration in which the fluid inlet (127, 128) has an initial cross sectional area to a deformed configuration in which the fluid inlet has an altered cross sectional area in response to a pressure differential between the interior of the housing and the exterior of the housing. The change in cross sectional area of the inlet can be made to vary independence on the pressure in the canister and can be used to control the rate of flow of the fluid through the inlet as the pressure in the canister falls during use.
A combined preform and blow moulding apparatus (10) has at least two processing stations (12, 14, 16) arranged one above another, including an upper, preform moulding station (12) having a preform moulding cavity (18a) and a lower, blow moulding station (14) having a blow moulding cavity (26). The cavities (18a, 26) being interconnected by means of an internal passageway (18) and the apparatus further comprising a transport system (32, 42, 42, 66) for moving a preform (49) downwardly from the upper, preform moulding cavity (18a) to the blow moulding cavity (26) along the passageway. The apparatus may also include an intermediate processing station (16) in which the preform (49) may be retained for cooling/normalization prior to being transported to the blow moulding station (14).
