Abstract:
1. An assembly for aseptically storing a substance in a flexible pouch, dispensing multiple portions of stored substance therefrom, and maintaining substance remaining in the flexible pouch in an aseptic condition sealed with respect to ambient atmosphere, wherein the assembly is receivable within a relatively rigid housing and adapted to cooperate with a pump for pumping discrete portions of the substance from the flexible pouch and through a one-way valve to dispense the substance therefrom, the assembly comprising: the 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 connectible in fluid communication with the substance from the variable-volume storage chamber and including a valve seat; and a valve portion overlying the valve seat, wherein the valve portion defines an interference fit with the valve seat, the valve portion and the valve seat define a normally closed valve opening therebetween, and the valve portion is movable 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 away from the valve seat to allow passage of substance from the variable-volume storage chamber through the valve opening, wherein in the normally closed and open positions the one-way valve maintains the substance remaining in the variable-volume storage chamber in the aseptic condition and sealed with respect to the ambient atmosphere; and a pump operatively coupled between the variable-volume storage chamber and the one-way valve, and a control unit electrically coupled to the pump to control operation of the pump and, in turn, control dispensing of substance within the variable-volume storage chamber, through the one-way valve, and out of the assembly.
