Claim:
A hinged cap device for use with a syringe comprising: a base defining an interior cavity for mounting onto a tip; a cap comprising a base wall, a first side wall, and a second side wall defining an open channel, wherein the cap is connected to the base by a living hinge, and wherein the cap is moveable from a ready position to an open position to expose a needle having a needle shaft and a needle tip, and from the open position to a secured position to prevent relative rotation between the cap and the base; a first latching mechanism on the cap for engaging the needle, the first latching mechanism locatable on a first side of the needle shaft in the ready position and locatable on a second side of the needle shaft in the secured position; wherein the needle is disengageable from the first latching mechanism in the ready position, and wherein the needle is not disengageable from the first latching mechanism in the secured position; and a second latching mechanism on the cap for engaging the base to prevent relative rotation between the cap and the base when the cap is in the ready position, wherein the second latching mechanism comprises two spaced apart tabs extending in a proximal direction away from the needle tip; wherein each tab of the two spaced apart tabs is adapted to abut a respective base tab located on the base; and wherein the two spaced apart tabs are separable from the two respective base tabs on the base by moving the cap axially along a lengthwise axis of the needle relative to the base.
