摘要:
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.

An apparatus comprises a hermetically sealed, sterile storage chamber, a dispensing valve including a hermetically sealed, sterile inlet; a pump coupled between the dispensing valve and storage chamber; and a sealing surface located between the dispensing valve and storage chamber. The sealing surface and/or the dispensing valve is movable relative to the other between (i) a sealing position hermetically sealing the dispensing valve relative to the storage chamber to thereby prevent fluid flow therebetween, and (ii) a non-sealing position allowing fluid flow therebetween.

An apparatus for storing fluid and dispensing multiple portions of a stored fluid therefrom. The apparatus comprises a container defining a variable-volume storage chamber for receiving therein the fluid and a dispensing valve including a valve inlet coupled in fluid communication with the variable volume storage chamber, and a valve member in fluid communication with the valve inlet and defining a normally-closed valve opening. The valve member is responsive to fluid at the valve inlet exceeding a valve opening pressure to move between (i) a normally closed position, and (ii) an open position permitting fluid flow through the valve opening. The dispensing valve defines a dispensing axis defining a direction substantially along which fluid is dispensed from the valve, and further includes an outlet surface over which dispensed fluid flows oriented at an acute angle relative to the dispensing axis for preventing the collection of residual dispensed fluid thereon.

A container is provided for storing a product, such as a fat containing liquid product, and includes a body defining a chamber for receiving the product; and a container closure including a sealing portion for sealing the product within the chamber. The container closure includes a member forming a substantially fluid-tight seal between the container closure and the body; a nipple in fluid communication with the chamber that seals the chamber with respect to the ambient atmosphere during storage of the product in the chamber and that can be opened to dispense product from the chamber therethrough; and a needle penetrable and laser resealable portion that is penetrable by the needle for aseptically filling the chamber with the product, and that is thermally resealable by the application of laser radiation thereto to seal the product within the chamber.
