Abstract A fuel cap has a cover-handgripping portion and a threaded closure portion, which portions are maintained in assembly by a ring member. The ring member has integrally molded therewith a plurality of outwardly extending flexible fingers in a hinged relationship. The closure portion is inserted in the ring member prior to assembly within the handgripping portion. At assembly, the fingers of the ring member pivot inwardly at the hinge position to become engaged with an annular groove formed in the handgripping portion. The movement of the fingers results in an inner portion of the ring member being displaced to form a support shelf for the threaded closure. Engagement of the fingers with the groove portion of the handgrip prevents removal of the ring and therefore the closure member from the handgripping portion.
An improvement in fuel caps having a cover portion and a closure portion retained in said cover portion, said improvement comprising; a ring member having a central cavity with an axially extending wall; a plurality of flexible fingers molded integrally with said wall and each connected thereto by a hinge portion, each said finger extending outwardly from said wall and having an inner surface coextensive with said wall, said closure being freely insertable in said ring prior to assembly in said cover; and said cover having a wall portion with an annular groove formed therein so that upon assembly of said ring member in said cover said fingers will be pivoted on said hinge portion by abutment with said wall portion to displace said inner surface to a position oblique to said wall portion of said cover to prevent removal of said closure and said fingers being engageable in said annular groove to prevent separation of said ring and said cover.
