Abstract:
A filler neck closure apparatus comprisinga fluid conduit formed to include a fluid-conducting passageway and first and second valve seats associated with the fluid-conducting passageway, a seal mount movable in the fluid-conducting passageway, and a seal coupled to the seal mount to move therewith in the fluid-conducting passageway relative to the first and second valve seats to engage each of the first and second valve seats to establish a closed position in the fluid conduit and block flow of fluid in the fluid-conducting passageway, the seal including a body, a lower shoulder coupled to the body and arranged to engage the first valve seat upon movement of the seal to the closed position to establish a first sealed closure in the fluid-conducting passageway, and an upper shoulder coupled to the body and arranged to engage the second valve seat upon movement of the seal to the closed position to establish a second sealed closure in the fluid-conducting passageway in spaced-apart relation to the first sealed closure so that the first and second sealed closures cooperate to block flow of fluid through the fluid-conducting passageway.
