16. A kit comprising:
a container; and
a closure system,
wherein the container comprises an opening for accessing an interior of the container and a boundary surface adjacent to the opening,
wherein closure system comprises a stopper member, a cage member, a cover member reversibly mountable to the cage member, and a lock activation formation,
wherein the stopper member is made of an elastic material and has a plug portion configured to fit into the opening of the container and a cover portion configured to abut the boundary surface adjacent to the opening of the container,
wherein the cage member is made of a shape-retentive material, and
wherein the closure system is configured to be in an assembled state in which the plug portion of the stopper member is fitted into the opening of the container, the cover portion of the stopper member abuts the boundary surface of the container and the cage member is mounted to the container,
wherein the cage member has a locking structure,
wherein the locking structure of the cage member is configured, in the assembled state of the closure system, to be in a detached position in which the locking structure of the cage member is disengaged from the container, and in a fixed position in which the locking structure engages a corresponding structure of the container,
wherein the lock activation formation is configured to interact with the cage member such that the cage member changes from the detached position to the fixed position,
wherein the lock activation formation has a surrounding member configured to, in the assembled state of the closure system, at least partially surround the locking structure of the cage member, and
wherein the lock activation formation comprises an activator configured to, in the assembled state of the closure system, move the surrounding member of the lock activation formation from a non-activating position to an activating position, and wherein the cover member has at least one through hole and the activator of the lock activation formation is shaped to access the surrounding member of the lock activation formation through the at least one through hole of the cover member.
