ABSTRACT:
A push-on filler neck cap for a fill passageway of a tank. The cap is provided with a push top and a dependent housing sized to fit within the fill passageway and with a fill passageway seal that is located at the lower inserted end of the housing and wherein the can is also provided with a restraining mechanism located between the push top and the fill passageway seat for securing the cap to the passageway in a sealed manner. The restraining mechanism is defined by a plurality of lugs which: 1) engage into a recess in the fill passageway; 2) pivot outward from the housing to engage the recess in response to movement of a spring biased lever pivotedly mounted to the push top with the recess; and (3) are biased to pivot outwardly for engagement with the recess by a spring located within the housing, which spring also urges the seal into its sealing relationship within the fill passageway.
