Definitions

  • the present invention concerns a closure system for a receptacle.
  • Such a closure system comprises in a known manner:
  • Such a configuration of the retaining collar and the retaining elements allows, during the unscrewing of the closure cap, immobilizing the tamper-proof ring and therefore causing a breakage of the frangible elements connecting the fastening skirt and the tamper-proof ring.
  • Such a breakage of the frangible elements ensures an easy check of any prior opening of a receptacle equipped with the aforementioned closure system.
  • the retaining elements in view of the flexibility of the retaining elements, in rare cases, these may be elastically deformed and bypass the retaining collar during an unscrewing of the closure cap. In such cases, the tamper-proof ring is likely to fall by gravity into a container into which the content of the receptacle equipped with the closure system is intended to be poured, and therefore to be ingested by the consumer.
  • the present invention aims to overcome this drawback.
  • the technical problem underlying the invention therefore consists in providing a closure system for a receptacle which has a simple and economical structure, while ensuring a reliable retention of the tamper-proof ring on the neck portion.

  • the closure system may further have one or more of the following features, considered alone or in combination.
  • the tamper-proof ring is intended to be mounted on the neck portion.
  • the neck portion and the tamper-proof ring are configured such that the retaining collar defines an annular hooking housing at least until the first screwing back of the closure cap on the neck portion after breakage of the frangible elements.
