Abstract: A closure for a container has a base and a lid. The base is attachable to the container. The lid is pivotally connected to the base and moveable between open and closed positions. The lid or the base has operating tabs on its periphery. Each operating tab has an actuation portion and an engagement portion. The engagement portion is moveable between engagement and disengagement positions. When the lid is in the closed positioned, the engagement portion engages the other of the lid and the base in the engagement position and disengages from the other of the lid and the base in the disengagement position. The actuation portion of the operating tab is resiliently deflectable radially outward relative to the one of the lid and the base to move the engagement portion to the disengagement position whereupon release of the actuation portion, the engagement portion returns to the engagement position.
