Abstract
A cover for covering closure plugs and openings and the like comprises a generally circular plate with axially positioned and extending latching fingers for engaging the corners of intersecting walls of a tool cross slot upon rotation of the cover for releasably retaining the cover in place over the plug.
Claims14
A cover assembly for a closure comprising in combination:
- a closure having a generally circular cylindrical configuration with an axis, a generally flat planar top surface and a threaded generally cylindrical portion on the opposite side thereof from said top surface for threadably engaging and securing to the opening of a receptacle;
- a cross slot recess formed of slots having vertical walls intersecting at a right angle and forming corner edges parallel to said axis at the intersection of said slots in said top surface;
- and
- a flat planar cover for covering said closure, said cover having a releasable gripping means comprising a plurality of elastic fingers extending from a surface thereof in a circular array for selectively extending into said slots at a first rotary position of said closure and for selectively engaging and gripping the corner edges at a second rotary position for retaining said cover in position over said closure.

A closure and cover assembly comprising in combination:
- a cylindrical sleeve having an outer surface for engaging and bonding into a cylindrical opening in a receptacle and a threaded inner bore for receiving a threaded closure;
- a closure having a generally circular configuration with a generally flat planar top surface and a threaded cylindrical portion on the opposite side thereof from said top surface for threadably engaging and securing into the threaded bore of said sleeve for closing the opening of a receptacle;
- a cross slot recess formed of slots having vertical walls intersecting at a right angle forming corner edges parallel to the axis of said closure in the center of said top surface for receiving a tool for applying a torque thereto;
- and
- a circular flat planar cover for covering said closure said cover having releasable gripping means comprising a plurality of elastic fingers, each having a step tapered forward end defining a gripping edge disposed in a circular array extending from a surface at the axis thereof for extending into said slot recess at a first rotary position and for selectively engaging the corners formed by the intersecting walls of said slots at a second rotary position for releasably retaining said cover in position over said closure.
