    Abstract: A flexible pouch defining a variable volume storage chamber and one-way valve assembly for aseptically storing a substance, dispensing multiple portions of the stored substance therefrom in cooperation with a pump, and maintaining substance remaining in the pouch in an aseptic condition sealed with respect to ambient atmosphere. The one-way valve includes a valve seat and elastic valve cover portion overlying the valve seat forming an interference fit therewith defining a normally-closed seam therebetween. The valve portion is movable radially between (i) a normally closed position with the valve portion engaging the valve seat, and (ii) an open position with at least a segment of the valve portion spaced radially away from the valve seat to allow substance from the storage chamber through the valve opening. The one-way valve maintains substance remaining in the variable-volume storage chamber in an aseptic condition sealed with respect to the ambient atmosphere.

    Abstract: A container and valve assembly for storing and dispensing substances including edible substances. The container has a body that has a storage chamber for storing the substance and a head portion for holding the valve assembly. The valve assembly includes a valve body and a valve seat surrounded by a flexible outer cover that includes a valve portion. A seam between the valve portion and valve seat form a one-way release valve wherein a portion of the seam remains closed when the substance is dispensed. To dispense the substance, pressure is applied to the body forcing the substance into the valve assembly, which in turn, controls the flow and release of the substance without exposing the remaining substance to the external atmosphere; thus, the sterility of the storage chamber and remaining substance is maintained, and the shelf life of the substance is increased.

    Abstract: An ophthalmic dispenser and method of filling and dispensing fluid stored therein. The dispenser includes a rigid housing defining a fluid-receiving chamber, a flexible bladder receivable within the fluid-receiving chamber, a pump coupled in fluid communication with the fluid-receiving chamber, and a nozzle having a valve defining an annular, axially-extending valve seat, an outlet aperture coupled in fluid communication between the valve seat and the pump, and a flexible valve cover extending about the valve seat and forming an annular, axially-extending interface therebetween. The valve interface is connectable in fluid communication with the outlet aperture, and at least part of the valve cover is movable between (i) a normally closed position with the valve cover engaging the valve seat to close the interface and form a fluid-tight seal therebetween, and (ii) an open position with at least part of the valve cover spaced away from the valve seat in response to pumped fluid flowing through the outlet aperture at a pressure greater than a valve opening pressure to allow the passage of pressurized fluid therebetween. The rigid housing is mountable within a cartridge which, in turn, is mountable within a dispenser housing including an eyelid depressor and a trigger for simultaneously actuating the eyelid depressor and pump.

    Abstract: An apparatus has a valve body defining a first passageway, a valve seat, and a flow aperture extending through the valve body and coupled in fluid communication with the first passageway. A valve cover of the apparatus is formed of an elastic material and includes a cover base mounted on the valve body and fixedly secured against movement relative thereto, and a valve portion overlying the valve seat. The valve portion defines a predetermined radial thickness and forms an interference fit with the valve seat. The valve portion and the valve seat define a normally closed, axially-extending valve opening therebetween. The valve portion is movable between a normally closed position with the valve portion engaging the valve seat, and an open position with at least a segment of the valve portion spaced away from the valve seat to connect the valve opening in fluid communication with the flow aperture to thereby allow the passage of fluid from the flow aperture through the valve opening. A hermetically sealed variable-volume storage chamber stores therein multiple portions of the fluid and is connectible in fluid communication with the one-way valve assembly. A pump is coupled between the variable-volume storage chamber and the one-way valve assembly, and is configured to pump discrete portions of fluid from the variable-volume storage chamber, through the flow aperture, and through the valve opening to dispense the portions of fluid through the valve assembly.
