    Abstract: A method for storing fluid and dispensing multiple portions of the stored fluid uses a container defining a variable-volume storage chamber; a dispensing valve including a valve inlet coupled in fluid communication with the variable-volume storage chamber, and an elastic valve member in fluid communication with the valve inlet and defining a normally-closed valve opening; a manually engageable actuator; and a pump including a compressible member defining a compression chamber coupled in fluid communication with the variable-volume storage chamber. Multiple portions of the stored fluid are hermetically sealed in the variable-volume storage chamber. The actuator is manually engageable and movable between (i) a first position wherein the compression chamber defines a first volume, and (ii) a second position wherein the compression chamber defines a second volume less than the first volume. In the second position the fluid in the compression chamber exceeds a valve opening pressure and, in turn, moves the elastic valve member between (i) a normally closed position hermetically sealing the one-way valve and variable-volume storage chamber with respect to ambient atmosphere, and (ii) an open position permitting fluid flow through the valve opening.

    Abstract: A flexible pouch and valve assembly is provided for aseptically storing a substance, dispensing multiple portions of the stored substance therefrom, and maintaining substance remaining in the pouch in an aseptic condition sealed with respect to ambient atmosphere. The flexible pouch and valve assembly are receivable within a relatively rigid housing, and are adapted to cooperate with a pump for pumping discrete portions of substance from the pouch and through the one-way valve to dispense the substance therefrom. The assembly comprises a flexible pouch defining therein a variable-volume storage chamber sealed with respect to the ambient atmosphere for aseptically storing therein multiple portions of the substance. A one-way valve of the assembly includes a valve body defining an axially-extending valve seat and at least one flow aperture extending through the valve body and/or the valve seat. A valve cover is mounted on the valve body, and includes an axially-extending portion formed of an elastic material overlying the valve seat and covering a substantial axially-extending portion thereof. 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 an axially-extending seam therebetween forming a normally closed, axially-extending valve opening, and 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 connect the valve opening in fluid communication with the at least one flow aperture and thereby allow the passage of substance from the variable-volume storage chamber through the valve opening. In the normally closed and open positions, the one-way valve maintains substance remaining in the variable-volume storage chamber in an aseptic condition and sealed with respect to the ambient atmosphere.

    Abstract: A container and method are provided for storing fat containing liquid products, such as infant or baby formula, or other milk-based products. The container includes a body defining a storage chamber for receiving the aseptic fat containing liquid product, and a first aperture in fluid communication with the storage chamber. The body does not leach more than a predetermined amount of leachables into the fat containing liquid product and does not undesirably alter a taste profile of the fat containing liquid product. A container closure assembly includes a stopper receivable within the first aperture for hermetically sealing the storage chamber. The stopper includes a first material portion defining an internal surface in fluid communication with the storage chamber forming at least most of the surface area of the container closure that can contact any fat containing liquid product within the storage chamber and that does not leach more than a predetermined amount of leachables into the fat containing liquid product or undesirably alter a taste profile of the fat containing liquid product. A second material portion of the stopper either (i) overlies the first material portion and cannot contact any product within the storage chamber, or (ii) forms a substantially lesser surface area of the container closure that can contact any product within the storage chamber in comparison to the first material portion. The second material portion is needle penetrable for filling the storage chamber with product, and a resulting needle aperture formed in the second material portion is thermally resealable such as by the application of laser energy to seal the product within the storage chamber. A sealing portion of the container closure is engageable with the body prior to needle filling the storage chamber to thereby form a substantially dry hermetic seal between the container closure and body.
