Definitions

  • This invention relates to a pierceable membrane type safety seal suitable for use on multi-dose bottles. It relates, more specifically to a simplified opening and closing device concurrently forming a safety seal for the contents.
  • Sealing systems for bottles or open vials have long been known in the pharmaceutical field; these consist, essentially, of a real rubber sealing element, tightly secured on the mouth of a vessel by a metal operculum caulked on the rim of the bottle neck and having in its center part an opening or a stress-raising line for removal of a metal disc corresponding to an underlying thinned portion of the rubber membrane apt to be easily perforated.
  • the object of this invention is to provide a type of plastic closure which allows an easy access to the elastic membrane to be perforated, without the aid of tools, while protecting the content of vessel against possible tampering.
  • the sealing device consists substantially of a plastic cover movably secured to a metal closing and locking element tightly applied by caulking to the mouth of the bottle or vial, with a pierceable elastic membrane interposed between.
  • cover 1 consists of a plastic disc 2, provided with a cylindrical circumferen tial flange 3, obtained by integrally moulding with disc 2.
  • a second cylindrical flange 4 located centrally and facing in the same direction as circumferential flange 3, is provided in disc 2 and is coaxial with respect to the cylindrical circumferential flange 3.
  • central cylindrical flange 4 is discontinuous or interrupted; in this position and slightly offset in a radial direction a wedge 5 is provided, the development of which slightly exceeds the interruption or discontinuity of cylindrical central flange 4 and the maximimum thickness of which is equal to about one third the height of central flange 4.
  • the locking metal element or capsule 6, as shown in Figs. 3 and 4, is provided with a cylindrical circumferential flange 8 the height of which considerably exceeds that of circumferential flange 3 of plastic cover 1.
  • An opening 9 is provided in the center of metal disc 7; the size of said opening is sufficient to permit access to the pierceable rubber membrane to be applied on the mouth of the container to be sealed. At one of its diameters opening 9 extends in two symmetrical eyelets 10.
  • an outer circumferential rib 11 can be formed by drawing in a radial direction with respect to eyelets 10.
  • the metal securing element 6 thus constructed is inserted in the hollow part of cover 1 of adequate size, so that the outer surface of disc 7 and cylindrical flange 8 coincide exactly with the inside surface of the plastic disc 2 and relevant circumferential flange 3. To achieve this it is necessary that the higher portion of wedge 5 penetrates in one of the two eyelets 10, while the cylindrical center flange 4 enters exactly into hole 9 projecting inside the metal element 6.
  • the integral assembly thus obtained is then applied to the mouth of the bottle or vial to be sealed (on which the sealing elastic membrane has been previously applied) and is firmly secured by a caulking procedure.
  • plastic cover 1 once it has been removed, cannot be returned to its original position of engagement with metal element 6, due to the particular structure of its component elements, it can however be re-utilized as a temporary covering and protection for metal element 6 and for the underlying rubber membrane when the contents of the bottle are to be partially used.
