Abstract
Abstract A universal gas cap adapted to lock to gas tank filler necks of different sizes. The cap includes a cup-shaped member having a transverse wall and perimetral flange or skirt depending therefrom which is adapted to engage the outer surface of a large diameter filler neck. A central cylinder which carries latching tongues that are biased toward the skirt or flange is carried by the transverse wall and is concentrically located with respect to the skirt. The outer surface of the cylinder is adapted to engage the inner surface of a small diameter filler neck and the tongues are arranged to engage notches provided in the flange portion of either neck to secure the cap to the neck. Annular gasket means mounted to the cylinder sealingly engage the filler neck top.

A gas cap adapted for universal use with both large dimension and small dimension filler necks, said cap comprising, in combination: an inverted cup-shaped cap member of a maximum diametral dimension larger than the greatest diameter of the large dimension filler neck, said cup-shaped cap providing a downwardly extending perimetral flange and a transverse wall, a plurality of circumferentially-spaced and radially inwardly extending and axially elongated ribs on the perimetral flange terminating at their radially inner edges along the perimeter of an outer circle just slightly larger than the greatest diameter of the large dimension filler neck so as to provide an outer guide for telescopically receiving the end of a large dimension filler neck, a central cylinder extending downwardly from adjacent the transverse wall of the cup member to a point below the lowermost edge of the cylindrical perimetral flange and located concentric with said outer circle and having a maximum diameter just slightly less than the least diameter of the small dimension filler neck so as to provide an inner guide for telescopically entering the end of a small dimension filler neck a pair of substantially radially reciprocable latching tongues carried by the central cylinder with the adjacent sides of said tongues substantially at a diameter of the cylinder, the size of the latching tongues and range of movement thereof being selected so that when withdrawn within the central cylinder they do not interfere with telescoping movement of the central cylinder into a tubular filler neck and when projected outwardly they extend substantially to the perimeter of the outer circle, the positioning of the latching tongues on the central cylinder being such that the latch edges thereof lie in a plane located between the transverse wall of the cap and the distal axial ends of the ribs on the perimetral flange of the cap, and annular gasket means grippingly fitted onto the central cylinder and located axially in the space between the latch edges of the latching tongues and the transverse wall of the cap.
