  • Patent number: 5374255
    Abstract: The present invention is an improved needle cover assembly for a syringe. The needle cover assembly includes a first half and an opposite unequal second half with an arc shaped inner shell such that the first half encloses the arc shaped inner shell of the second half of the needle cover assembly. The arc shaped inner shell of the second half extends over the tip of the needle and the first half of the elongated cover member extends over both the arc shaped inner shell and the tip of the needle for providing double protection. The two halves of the needle cover assembly are attached to a frustum shaped base member such that a hollow hub member can be press-fitted into the frustum shaped base member. A rotatable collar surrounds the frustum shaped base member, and when the rotatable collar is rotated approximately 90.degree.
