Hypodermic syringe tray

Claim 2

In a package bottom tray comprising a bottom, side walls and end walls, constructed to house at least one sterile, disposable hypodermic syringe equipped with a deformable cannula cover and containing a sterile liquid, the improvement which comprises cannula cover- and plunger-securing means disposed in such manner as to minimally exert an equal and opposite force to that exerted against said cannula cover and plunger by thermal expansion of liquid contained within said syringe, said cannula cover securing means abutting the distal end of the syringe ferrule, locking said cannula cover thereo.

Claim 3

A package bottom tray as described in claim 1 in which said sterile liquid contains a medicament.

Claim 4

A package bottom tray as described in claim 1 in which said cannula cover-securing means is a vee block disposed in such manner in relationship to said cannula cover to exert a frictional force in an opposite direction to that of liquid expansion within said syringe.

Claim 5

A package bottom tray as described in claim 1 in which said plunger-securing means is the end wall of said package bottom tray.

Claim 6

A package bottom tray as described in claim 1 in which said plunger-securing means is a finger integral with said end wall, projecting substantially perpendicular from said end wall to contact the plunger bushing.

Claim 7

A plunger-securing means as described in claim 5 in which said finger is cylindrical.

Claim 8

A plunger-securing means as described in claim 5 in which said finger is a truncated conical projection.

Claim 9

A package bottom tray as described in claim 1 in which there is at least one septal cradle to support said syringe barrel.

Claim 10

A package bottom tray - hypodermic syringe assembly comprising the package bottom tray of claim 1, having disposed therein at least one hypodermic syringe comprising a cartridge and hypodermic needle joined by a ferrule, said needle being disposed in a cannula cover, said cartridge and needle housing a sterile liquid contained by a plunger disposed within said cartridge and a core pin disposed to seal the open end of said needle, said cartridge resting on a septal cradle disposed in the bottom tray with said cannula cover being held by cannula cover-securing means which prevent longitudinal displacement of the cover while permitting vertical removal of the entire syringe, said cannula cover-securing means abutting said ferrule and preventing movement of the open end of said cartridge from said tray end wall.

Claim 11

A package bottom tray - hypodermic syringe assembly as described in claim 9 in which said sterile liquid contains a medicament.
