1. A releasing stopper, suitable for and/or intended to be removably coupled with a container and configured to contain and selectively release a substance in the container,
the stopper comprising:
a first body configured to be directly coupled with the container and comprising a coupling element suitable for allowing the removable fastening of the releasing stopper in correspondence of an opening of the container defining a first mounting configuration of the releasing stopper on the container wherein, preferably, the releasing stopper closes the container;
a second body, coupled and movable with respect to the first body and defining with the first body at least one reservoir configured to contain the substance, the reservoir being insulated from the outer environment in at least a first closed configuration of the releasing stopper, wherein the reservoir, at least in said first closed configuration of the releasing stopper, progressively reduces its volume as a result of a movement of the second body with respect to the first body,
a closing element, positioned on the first body and constituting at least a portion of a wall of the reservoir and facing the inside of the container in the mounting configuration, the closing element being configured to be selectively openable and/or breakable, defining at least a second open configuration of the releasing stopper, through the action of a perforation or opening element different from the releasing stopper and housed within the container, to make the reservoir be in communication with the inside of the container;
the second body comprising a cavity configured to allow the removable engagement of an ending portion of the perforation or opening element;
wherein, in said at least a first closed configuration of the releasing stopper in which said reservoir is insulated from the outer environment, the second body cooperatively interacts with the first body for defining, with said first body, said at least one reservoir configured to contain the substance insulated from the outer environment.
