1. A dispensing apparatus for dispensing fluid comprising:
- (a) a fluid dispenser comprising;
(i) a housing assembly including a housing having a fluid reservoir, said reservoir having a fluid inlet for filling said reservoir with fluid and a fluid outlet for permitting fluid flow from said fluid reservoir, said housing assembly having a dispenser connector; and
(ii) stored energy means for acting upon the fluid contained within said reservoir to cause the fluid to controllably flow through said outlet, said stored energy means comprising a compressively deformable, elastomeric member carried within said reservoir, said elastomeric member being expandable to cause fluid flow from said reservoir toward said fluid outlet; and
(b) a reservoir fill assembly for filling said reservoir with the fluid to be dispensed, said reservoir fill assembly comprising;
(i) a container subassembly including a container having a body portion, a fluid chamber, and first and second open ends;
closure means for sealably closing said first open end of said container; and
a plunger telescopically movable within said container from a first location proximate said second open end to a second, spaced-apart location;
(ii) an adapter subassembly comprising a hollow housing having an annular passageway and a first open end for telescopically receiving a part of said body portion of said container of said container subassembly and a second end, said hollow housing further including an adapter connector mateably interconnectable with said dispenser connector for removably interconnecting said adapter subassembly with said fluid dispenser; and
(iii) an adapter sleeve telescopically receivable with said annular passageway said sleeve subassembly including pusher means for engagement with said plunger to move said plunger within said container between said first and second locations.

Abstract
A compact fluid dispenser for use in controllably dispensing fluid medicaments and a cooperating reservoir fill assembly for controllably filling the fluid reservoir of the fluid dispenser. The fluid dispenser component includes a novel stored energy source in the form of an expandable, elastomeric member of unique construction that provides the force necessary to continuously and substantially uniformly expel fluid from the reservoir of the dispenser component. The fluid dispenser component further includes a fluid flow control assembly that filters and precisely controls the flow of the medicament solution from the reservoir of the dispenser container.
