Definitions

  • This arrangement enables the insert to be charged with gas and stored at atmospheric pressure, with the valve preventing gas leakage.
  • the charging pressure can be increased during the pasteurisation of the beverage.
  • the valve opens as the pressure increases during pasteurisation and recloses as the pressure drops on cooling. During this procedure, gas, beverage, or a mixture from the container, enters the insert and is retained in the insert. The valve remains closed after the container is opened and gas or gas/beverage mixture is jetted solely through the second orifice.
  • Plastics have substantial advantages for ease of manufacture of an insert, but provide a substantial disadvantage.
  • the insert should be made of a material which permits recycling.
  • Fig.22 is a graph, similar to Fig.21, for a similar film, which has been soaked in beer, the film being at room temperature;
  • the strip 26 has sufficient rupture strength to permit prolonged storage of the insert in dry conditions. Within the can, however, the exposure to the can contents weakens the strip. The differential pressure across the strip in the can is insufficient to rupture the strip, but the sudden drop in pressure, on opening the can, causes rupture and the seal bursts open to permit jetting of gas into the can contents.
  • the strip 26 may be made of an ethylene vinyl alcohol (EVOH) copolymer film.
  • the copolymer preferably includes 40% or less of ethylene monomers and in one example comprises 32% ethylene monomers.
  • a suitable material is commercially available as type EF-XL. This film is 15 microns thick and is biaxially oriented.
  • the arrangement shown in Fig 2 is modified by provision of a gas barrier layer on the internal face of the disc 23 of the insert body, the jetting orifice being in the disc instead of a substrate, as in Fig 6.
  • the disc 123 has a jetting orifice 125 closed by a sealing member 126 and the lower chamber 152 contains a gas, which may be air, under atmospheric, or low pressure.
  • the control member 231 is constructed to withstand the pressure differentials caused by the pasteurisation and cooling steps.
