A tip cap is provided for positive sealing engagement with the tip of a syringe barrel. The tip cap includes an inner cap formed from an elastomeric material dimensioned for sealing engagement with the tip of the syringe barrel. The tip cap further includes an outer cap engaged with the inner cap to limit or prevent both axial movement and rotational movement therebetween. The outer cap includes an array of threads for threaded engagement with a luer collar. The luer collar may be a separate component mountable to a syringe barrel or an integral part of the syringe barrel.

[ What is claimed is:] [1.] A tip cap assembly for use with a hypodermic syringe barrel having a fluid-receiving chamber and a distally projecting tip with a fluid passageway extending therethrough, said tip cap assembly comprising:a collar securely engageable around the tip;an inner cap having opposed proximal and distal ends, with said proximal end sealingly engageable with the tip, said inner cap being formed of an elastomeric material, at least a portion of said inner cap intermediate said proximal and distal ends includes an annular undercut;a rigid outer cap having an open distal end to accept said inner cap with said rigid outer cap securely disposed around said inner cap and releasably engaged with said collar, said rigid outer cap including at least one inwardly extending annular rib disposed and dimensioned to engage in said annular undercut in said inner cap surface; andsaid assembly being configured so that said inner cap sealingly engages the tip when said collar is securely engaged around the tip to seal a fluid contained in the fluid-receiving chamber of the syringe barrel, and said inner cap is disengageable from the tip in response to disengagement of said rigid outer cap from said collar.
