ABSTRACT:
A combination cap and needle unit permits a syringe tube to be capped for storage or prepared for use with the needle in operative position to inject fluid. The cap structure fits removably on the syringe tube and carries a rubber seal element that initially seals the tube outlet. The needle is connected integrally with the cap by a frangible heat seal which may be broken to release the needle so that it may be pierced through the rubber seal element.
