Claim 12

The needle cap of claim 8 wherein the guard is generally flat and disk-shaped.

Claim 13

The needle cap of claim 8 wherein the guard is funnel-shaped, and opens toward the open end in the cap.

Claim 14

An improved needle cap of the type comprising a generally cylindrical hollow tubular body section, having a closed first end and an open second end for receiving the needle, the improvement comprising: (a) a funnel-shaped lip surrounding the opening in the second end, and projecting radially and axially from the second end, in combination with means for spacing the user's fingers from the second end of the cap, the said means comprising a funnel-shaped guard extending from the body section intermediate the ends, the guard opening toward the open end of the cap, the guard positioned sufficiently close to the funnel-shaped lip that it is difficult to grip the cap between the guard and the lip.

Claim 15

An improved needle cap of the type comprising a generally cylindrical hollow tubular body section, having a closed first end and an open second end for receiving the needle, the improvement comprising: (a) a funnel-shaped lip surrounding the opening in the second end, and projecting radially and axially from the second end, in combination with means for spacing the user's fingers from the second end of the cap, the said means comprising a funnel-shaped guard extending from the body section intermediate the ends, the guard opening toward the open end of the cap, the guard positioned sufficiently close to the funnel-shaped lip that it is difficult to grip the cap between the guard and the lip.

Claim 16

A safety needle cap comprising a generally cylindrical, hollow tubular body section, having a closed first end, an open second end for receiving the needle, and a funnel-shaped lip surrounding the open end and projecting radially and axially outwardly from the open end to channel needles into the open end, the lip projecting radially outwardly sufficiently to protect fingers gripping the cap, and a guard extending from the body section intermediate the two ends to intercept needles missing the funnel-shaped lip, the guard being funnel-shaped and opening toward the open end in the cap, the guard positioned sufficiently close to the lip to make it difficult for the user to grip the cap between the lip and the guard.

Claim 17

A safety needle cap comprising a generally cylindrical, hollow tubular body section, having a closed first end, an open second end for receiving the needle, and a funnel-shaped lip surrounding the open end and projecting radially and axially outwardly from the open end to channel needles into the open end, the lip projecting radially outwardly sufficiently to protect fingers gripping the cap, and a guard extending from the body section intermediate the two ends to intercept needles missing the funnel-shaped lip, the guard being funnel-shaped and opening toward the open end in the cap, the guard positioned sufficiently close to the lip to make it difficult for the user to grip the cap between the lip and the guard.

Claim 18
