Disposable dispensing syringe vial

Claim 1

In combination, a cylindrical syringe vial having a shoulder drain point and a neck with a flanged axial opening, a flangemounted diaphragm sealing the opening and defining with the vial a vial chamber characterized by an open, unobstructed neck portion, the diaphragm having an exterior target surface pierceable for access into the vial chamber by a hub-mounted cannula having a shank sufficiently long to reach the drain point, the diaphragm including resilient elastomeric coupling means surrounding and extending outwardly from the target surface to define coaxial socket means located outside of the opening and being adapted to receive a syringe hub extension in matching fluidtight engagement, the coupling means and diaphragm preventing entry of the syringe hub into the neck portion and being sufficiently resilient to bend controllably while maintaining said fluidtight engagement to a position such that the outer end of the coupling means is substantially off-line from the central axis of the vial and the end of the cannula shank is engageable with the drain point whereby a syringe so received can be manipulated for offcenter aspiration and liquid content introduced into the vial can be aspirated from the vial without operational loss when the vial is positioned for drainage upon its drain point.
