  • Patent number: 10906680
    Abstract: The present invention relates to a puncture resistant sealable vapour barrier sterilisation bag capable of withstanding a steam sterilisation process whilst providing an effective microbiological barrier having a first sealable opening suitable for receiving items to be sterilised and a second sealable opening adapted to couple to a sterilisation conduit. A third sealable opening may be provided in the bag to facilitate circulation within the bag via the second and third openings when the first opening is sealed. The bag forms the means for sterilising an article(s) solely within the plastic bag in conjunction with a sterilisation services supply device. The bag is preferably formed of plastics. Preferably a multilayer construction including a puncture resistant outer layer and a heat-sealable inner layer. The bag may include a covert marking technology and/or a readable unique identification code such as a tamper-resistant label applied to the bag to facilitate uniformity and traceability.

  • Publication number: 20150314899
    Abstract: A method of sterilising items by placing items to be sterilised into a puncture resistant sealable vapour barrier sterilisation bag, performing steam sterilisation under pressure via a conduit coupled to the bag whilst maintaining a heated compensating pressure environment around the exterior of the bag during steam sterilisation so as to reduce mechanical stress on the hag and sealing the bag at the completion of sterilisation. There is also provided a sterilisation services apparatus for sterilising the contents of a sterilisation bag including a pressure compensating compartment having a sealable door that maintains a heated compensating pressure environment around the exterior of a sterilisation bag during steam sterilisation so as to reduce mechanical stress on the bag.

  • Patent number: 8327606
    Abstract: A method and apparatus for sterilization in which items to be sterilized are placed in an impervious sealable package and the sterilization process is carried out within the package. The apparatus (10) includes a cabinet (18) in which a package (P) preferably with a carrier (11) located within, can be positioned. A snorkel (17) is inserted into the package (P) and via connector (23) vacuum, pressure and sterilant can be applied to the interior of the package (P). A sealing arrangement (14b, 22b) can seal the package closed after the sterilization process has been completed.

  • Publication number: 20080286422
    Abstract: Apparatus for producing cheese blocks. The apparatus includes a cheese former for forming blocks of cheese. A plurality of moulds formed by a base (40) and lid (41). A loading station (20) in which a bagged block of cheese (14) is engaged in a mould base (40) and then enclosed by a lid (41). The bagged blocks of cheese in the moulds (40, 41) are then conveyed to a cooler for rapid cooling. Following this the moulds are moved to an unload station whereupon the blocks of cheese are removed from the moulds.
