Abstract
A tank cap has an upper longish handle portion engageable by a user's hand to open and close the cap relative to the tank. The handle also has, on each of its two sides, an indentation into which a screwdriver or the like can be inserted to aid in rotating the cap in the opening direction, the indentation being shaped so that if the inserted screwdriver is moved in the direction corresponding to closing of the cap the screwdriver will be cammed out of the indentation without over-tightening the cap in the closing direction.
