Abstract
A cap intended to be mounted on a container includes a base, a lid with a stopper, structure articulating the lid with respect to the base, with a hinge, a structure for locking the lid on the base, and structure for unlocking the locking structure.The lid is arranged to resist any relative movement between the lid and the base and to store mechanical energy by plastic deformation of at least one of the lid and the base and the unlocking structure is arranged in the form of a detent allowing the stored mechanical energy to be released in order to propel the lid to the open position.
