Abstract
A closure system for a receptacle having a neck in which an opening is formed and provided with outwardly projecting external threads each extending between a first end further from the opening and a second end closer to the opening, the system comprising a cap having a side wall that surrounds the neck and that fits substantially snugly over the shape of the external threads thereof. The cap is made of a material that is elastically deformable, and at least some of the threads of the neck are spaced apart in pairs by a circumferential distance around the neck that decreases progressively between the first and second ends of the threads.
