Publication number: 20120118764Abstract: A closure 40 for a container body includes a liner 46 which incorporates a hydrogen generating device comprising a hydride which generates hydrogen on contact with moisture. The liner may be an interference fit within the body 42. The liner 46 and other liners described may include control means for controlling passage of moisture to the hydrogen generating means and/or sealing means for sealing the closure to a container. In use, with the closure secured to a container, water vapour passes into liner 46 and contacts the hydride which generates hydrogen. A reaction between hydrogen and oxygen which has passed into the container takes place, catalysed by a catalyst, and water is produced. Thus, oxygen is scavenged.Type: ApplicationFiled: April 9, 2010Publication date: May 17, 2012Inventors: Ronald James Valus, Mark Rule, Andrew Stuart Overend, Christine Leeming, Steven Burgess Tattum

Publication number: 20120114529Abstract: A closure (40) includes a body (42) with a screw threaded portion (44) for engaging the closure with a container, for example a bottle. Inwards of portion (44) is a liner (46) comprising a hydrogen generating device, wherein the liner includes one layer (48) which incorporates a hydride dispersed in a polymeric matrix and, on opposite sides of layer (48) are arranged PET layers (50, 52). Layer (50) is arranged to act as a control layer to control the rate of passage of water vapour from the beverage in the container to the hydride containing layer (48) and thereby control generation of hydrogen by the hydrogen generating device. In use, water vapour passes through layer (50) and contacts the hydride associated with layer (48) which results in production of molecular hydrogen which combines with oxygen which may have entered a container with which the closure (40) is associated.Type: ApplicationFiled: April 8, 2010Publication date: May 10, 2012Inventors: Adrian John Carmichael, Andrew Stuart Ovenrend, Mark Rule, Ronald James Valus, Christine Leeming, Steven Burgess Tattum

Publication number: 20100028499Abstract: A container (22) includes a shell (24) made from a polymer, for example PET, and incorporating a catalyst, for example a palladium catalyst. A closure (40) incorporates a plug which includes a source of hydrogen, for example a hydride. In use, with container (22) including a beverage and closure (40) in position, the headspace in the container will be saturated with water vapor. This vapor contacts the hydride associated with plug (42) and as a result the hydride produces molecular hydrogen which migrates into the polymer matrix of shell (24) and combines with oxygen which may have entered the container through its permeable walls. A reaction between the hydrogen and oxygen takes place, catalysed by the catalyst, and water is produced. Thus, oxygen which may ingress the container is scavenged and the contents of the container are protected from oxidation.Type: ApplicationFiled: January 24, 2008Publication date: February 4, 2010Inventors: Mark Rule, Ronald J. Valus, Steven Burgess Tattum

Publication number: 20050182670Abstract: A method for arranging a life insurance transaction while managing risk exposure associated with the transaction is disclosed. In one embodiment, the method includes coordinating the initiation of an insurance policy that relates to the life of a person. Execution of a loan on behalf of an owner of the policy for the payment of premiums due on the policy is also coordinated with a lending entity. The posting of collateral for the loan by a third party is coordinated, thereby removing risk exposure from the lending entity, the policy owner, and/or the insured.Type: ApplicationFiled: February 18, 2005Publication date: August 18, 2005Inventor: Steven Burgess
