Definitions

  • the invention relates to a closure device for a cylinder comprising a collar provided with a bead outside at its free end and intended for a dispenser of liquid of the “water fountain” type.
  • the distribution of water by generally refrigerated fountains is a very common in countries such as the United States of America and some Asian countries.
  • the water to be distributed is delivered in cylinders with a capacity of five gallons (19/20 liters) which are placed upside down on the dispenser, the latter allowing distribute the water in smaller volumes, for example in glasses.
  • the invention relates more particularly to plugging devices commonly called “non-spill”, that is to say which allow, thanks to an internal valve system which releases the passage of water out of the cylinder only when the latter is in place on the distributor, to set up the cylinder on the distributor and remove it from the dispenser, even before it is empty, without risk the contents of the cylinder.
  • Such a device generally comprises a plastic capsule comprising a transverse end wall from which project in the same direction, on the one hand a substantially cylindrical outer skirt, provided with an inner bead for the hanging behind the bead of the neck of the cylinder and, on the other hand, a chimney substantially cylindrical interior intended to receive a withdrawal cannula provided on the distributor to come fit into the chimney from the transverse wall end of the capsule, when placing the bottle on the dispenser.
  • the device may include a tamper-evident seal molded in one piece. with the capsule and located at the start of the chimney, on the side of the transverse wall, so as to close off the chimney, the said cover being intended to be irremediably and visibly destroyed during the fitting of the withdrawal cannula in the chimney
  • a seal is generally placed against the inner face of the transverse wall of the capsule, between the outer skirt and the chimney.
