Definitions

  • the present invention relates to improvements made to the shutters for screwed necks and it relates more particularly to a shutter of the kind in question comprising a capsule whose inner part is associated with a seal.
  • Such a shutter must ensure an excellent seal, or even a good resistance to pressure on bottles to be subjected to different heat treatments such as pasteurization or even sterilization in certain extreme cases.
  • the shutters in question are intended to be used on returnable bottles whose dimensions of the neck bore have large tolerances, in other words the value of this diameter is variable in large proportions.
  • the bottles considered also have a large dispersion in terms of the shape of the "drink", that is to say the outside of the neck.
  • the shutters currently used do not generally give satisfaction to users whether they are made in one piece or in two elements.
  • the improvements which are the subject of the present invention aim to allow the production of a two-piece obturator, either a rigid capsule and a molded seal fixed inside this capsule, and which has a flexible lip suitable for being turned against the bottom of the capsule, the fixing of this seal being carried out by means of an elastic chimney which covers the seal so that the sealing is effected by intimate contact with the inside, the outside and the top of the neck. .
  • a shutter according to the invention comprising a capsule 1 and a seal 2 made respectively of polypropylene and ethylene-vinyl acetate (EVA).
  • EVA ethylene-vinyl acetate
  • the capsule 1 has a bottom 1a, the central part 1b of which is offset towards the outside so as to constitute a depression lc in the capsule.
  • the inner face of the skirt 1d of the capsule is provided with a thread 1e.
  • a tubular chimney 1f is made integral with the central offset part 1b of the bottom, that is to say that its origin is located in the depression Ic and at its junction with the bottom la.
  • This chimney is provided conical with opening towards the bottom, its free edge 1g being slightly opened in the direction of the skirt 1d.
  • the joint 2 is produced in the form of a heel or bowl 2a, the free edge of its side wall being extended by a frustoconical partition or lip 2b open in the direction opposite to that of the bowl 2a.
  • the capsule 1 When the shutter is placed on the neck 3 of a bottle, the capsule 1 is moved axially because its thread cooperates with that 3a of said neck. This displacement causes the entry of the tubular chimney If into the bore 3b of the neck 3 so that the corresponding part of the lip 2b of the seal 2 is applied elastically against the outlet of this bore.
  • the face lh of the capsule Ic squeezes another part of the lip of the seal 2 against the end 3c of the neck.
  • the action in question of the capsule produces a pinching of the lip rim considered between the interior of the skirt of the capsule 1 and the periphery of the neck 3 (fig. 3).
