A snap closure for a container includes an annular snap bead in a skirt portion. A top portion extends upwardly from the skirt portion, the top portion having horizontal slits. When the snap closure is engaged with a container, the snap beads snap onto a mating locking ring of the container. An upwards force is applied to the snap closure to disengage the closure from the container. The horizontal slits enable the top portion to flex axially to provide additional rotational leverage for disengaging the snap beads from the annular locking ring.
