Abstract: A dual dispenser includes a first container adapted to hold a first product, the first container including an end portion having at least one dispensing port and a second container adapted to hold a second product, the second container including an end portion having at least one dispensing port. The dual dispenser also includes a closure having at least one dispensing opening therein adapted to be in fluid communication with the at least one dispensing port of the first and second containers. The end portions of the first and second containers form a neck finish adapted to receive the closure. The neck finish and closure include engagement surfaces for rotatably mounting the closure on the neck finish such that the closure can rotate relative to the first and second containers.

Abstract: A cap for a container that stores and dispenses fluids or gels that includes a shroud having a shroud wall surrounding an opening and a collar connected on the shroud so that the collar selectively rotates relative to the shroud, is provided. The collar is rotatable between a closed position and an open position. The actuator is connected to the shroud, and has a contact portion. The contact portion is in the opening of the shroud. The actuator is movable in the closed position and the open position by a force that is applied to the contact portion only after removal of a tab.

Abstract: A valve is provided that includes a tip seal assembly, a mounting cup that has a hole, and a housing that is connected to the mounting cup. The tip seal assembly has a first portion through the hole forming a gap between the mounting cup and the first portion of the tip seal assembly. The tip seal assembly has a second portion in the housing. A shell seal is between the housing and the tip seal assembly covering the gap. The shell seal is deformable to form an opening between the housing and the tip seal assembly upon application of a predetermined pressure through the gap.

Abstract: An aerosol valve having a valve stem, valve stem housing, compression spring, and a hard stop formed by the interaction of valve stem and valve stem housing is provided. The hard stop prevents the compression spring from becoming fully compressed, or coil-bound, when the valve stem is pressed to dispense a product formulation from the container, thereby creating open spaces between coils of the compression spring and providing a defined flow path for the product formulation. The aerosol valve increases mixing and turbulence of the product formulation that reduce agglomerations of solids that might otherwise block the flow paths. The additional defined flow path also directs more of the product to the valve stem aperture, further increasing dispensing of the product formulation from the container. A method of using the aerosol valve is provided.

Abstract: An aerosol valve having a valve stem and compression spring geometry that create shorter flow paths, have fewer changes in flow direction, and passageways with large cross-sections to reduce resistance and back pressure is disclosed. The aerosol valve minimizes agglomeration of solids in the flow paths and reduces product failures. A method of using the aerosol valve is also provided.

Abstract: A dispensing apparatus which defines an outlet through which a metered dose of liquid from a reservoir is dispersed as an atomized spray. A droplet of liquid is metered onto a perforate membrane which is vibrated by way of a piezoelectric transducer such that atomized droplets are dispensed through the holes formed in the membrane. At each actuation of a delivery device, which provides the metered quantity of liquid, the transducer is actuated so as to vibrate the membrane for a period greater than the dispensing period required for the droplet to be dispensed. The apparatus is particularly suitable for dispensing pharmaceutical preparations.

Abstract: A dispensing device which includes a container for liquid to be dispensed, an outlet nozzle including a device to break-up a flow of liquid under pressure into a spray, a piston for forcing liquid out of the container under pressure and through the nozzle, and a drive device for moving the piston a predetermined distance to dispense a predetermined quantity of liquid from the container. The drive device includes a dose selector for selecting the predetermined amount of liquid and a plunger for moving the piston, movement of the dose selector determining subsequent movement of the plunger. The device is particularly suited to nasal administration of liquid.

Abstract: Dispensing apparatus 1 for a pressurized dispensing container has a valve, a valve actuator and a flow regulator comprising a washer 13 located in a housing 11 such that an aperture 14 of the washer forms a constriction presenting an impedance to the flow. The washer is resiliently deformable to vary the impedance presented by the constriction in response to variation in the pressure differential across the washer such that in use with a pressurized container having a finite resource of pressurizing gas the tendency for the flow rate to decrease with depletion of the gas pressure is compensated by a tendency for the flow rate to increase due to decreased impedance of the flow regulator. The washer has a recessed downstream face 16 which co-operates with a planar seat 15 of the housing such that the washer deforms towards the seat. The apparatus enables containers to be pressurized with nitrogen while maintaining a constant flow rate throughout the dispensing life of the container.
