On a safety can for the storage and dispensing of liquid fuel and other volatile liquids from which the contents usually are dispensed at more or less frequent intervals, the pouring spout of the can has a cover which is at a free end of a lever which is spring biased to normally keep the cover tightly closed. The can has a fixed lifting handle in the form of a flat arch in a central area of the top of the can with the top of the arch providing a hand grip removed from the spout and its cover, a secondary handle extending above the lever on which the cover is secured and pivotally secured through an upwardly offset connection to the lever toward the free end of the biased lever terminates in a hand grip parallel with but spaced radially from the hand grip formed by the flat arch. The can may be lifted by grasping the two parallel hand grips but the spout cover will remain closed until one's hand, grasping both grips is tightened to pull the hand grip of the secondary handle in a generally horizontal, or radial, direction toward the first to controllably lift the spout cover from the end of the spout to an open position. Up and down movement of said secondary handle is ineffective to open the cover, radial movement alone being ineffective except lifting the can with the secondary lever alone held the spout cover more tightly closed.
A safety can comprising a vessel with a closed top with a pouring spout near the periphery of the top, a primary fixed lifting handle slightly off-center on the top with a hand grip extending in a direction at right angles to the radius on which the spout is centered, a first lever mounted on the cover between the spout and the handle pivoted near one end to swing in a vertical arc above said radius with its free end extending above the pouring spout, a cover for the pouring spout suspended from the free end of said lever, spring means biasing said first lever to yieldably hold the cover tightly over the pouring spout, a secondary handle comprising a second lever having a hand grip at its free end parallel with the hand grip of the primary lifting handle, said second lever having an overcenter pivotal mounting on said first lever near to but inwardly from the center of said cover, said secondary handle being arranged to transmit lifting motion to the first lever to raise the cover from the spout only when moved in the direction toward the primary lifting handle.
