Tamper-Evident Pen Needle Outer Cover

Abstract:

A pen needle outer cover (10) has a molded plastic distal cover (20), and a molded plastic proximal cover (22) in place of the conventional paper-foil label. The proximal cover (22) may be snap-fit over the opening of the distal cover (20). A user-separable section (26) with a finger pull tab (32) is defined by a reduced-thickness membrane (24), which functions as a tear line to allow that section (26) to at least partially separate from the proximal cover (22). A living hinge (27) may be provided to keep the user-separable section (26) from completely separating from the proximal cover (22). The finger pull tab (32) may be configured to enable re-covering of a pen needle (30) that is still within the outer cover (10).
