Fluid delivery apparatus
First Claim
1. A fluid container assembly for use with a fluid delivery apparatus of the character having a base and a stored energy means for forming in conjunction with the base a fluid reservoir having an inlet and an outlet, said stored energy means being adapted to expel fluid from the fluid reservoir, said fluid container assembly comprising:
- (a) a container having a fluid chamber having an inlet and an outlet;
(b) a plunger telescopically movable within said fluid chamber of said container as a result of fluid pressure being exerted thereon by fluid introduced through said inlet; and
(c) inlet valve means disposed between said plunger and said inlet for controlling fluid flow into said chamber, said inlet valve means including a valve member movable in response to fluid pressure from a first valve closed position to a second valve open position.

Abstract
A fluid container assembly which can be aseptically filled in the field with selected fluids and one which is specially designed for sterile coupling and use with fluid dispensing and delivery devices of the character that embody stored energy sources such as compressible cellular masses and distendible elastomeric membranes that form, in conjunction with a cooperating base, fluid chambers for containing the fluid to be dispensed.
