Patent number: 10405566Abstract: A container (22) includes an oxygen-sensitive beverage, for example a vitamin C-containing beverage. A closure (40) seals the mouth (28) of container (22). The closure includes an oxygen scavenging structure, for example a closure, which comprises a hydrogen generating means and a catalyst for catalysing a reaction between hydrogen and oxygen.Type: GrantFiled: August 21, 2012Date of Patent: September 10, 2019Assignee: COLORMATRIX HOLDINGS, INC.Inventors: Adrian John Carmichael, Andrew Elkin, Mark Frost, Steven John Moloney, Andrew Stuart Overend, Steven Burgess Tattum

Patent number: 9511909Abstract: A closure (40) includes a body (42) with a threaded portion (44) for engaging the closure with a container. 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) acts 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. Thereafter, a reaction between the hydrogen and oxygen takes place, catalysed by a catalyst associated with the container thereby to scavenge the oxygen.Type: GrantFiled: April 8, 2010Date of Patent: December 6, 2016Assignee: COLORMATRIX HOLDINGS, INC.Inventors: Adrian John Carmichael, Andrew Stuart Ovenrend, Mark Rule, Ronald James Valus, Christine Leeming, James Stuart Leeming, Steven Burgess Tattum

Patent number: 9463887Abstract: A food container (2) includes a rigid thermoformed plastics carton (4) which holds a dry food 6 and is closed by a removable film closure (8). The film (8) incorporates a hydride which is arranged to generate hydrogen on contact with moisture. Additionally, the film (8) is arranged to have relatively high water vapour permeability and relatively low hydrogen gas permeability. In use, water vapour from air surrounding the container (2) passes into the film (8) and reacts with the hydride to generate hydrogen. Due to the relatively low hydrogen permeability of the film (8), the hydrogen is restricted from escaping from the container. Instead, the hydrogen then reacts with any oxygen within the container in a reaction catalysed by a catalyst also associated with the film closure (8), thereby to scavenge oxygen within the container (2) and protect the food (6) from oxidation.Type: GrantFiled: February 1, 2012Date of Patent: October 11, 2016Assignee: ColorMatrix Holdings, Inc.Inventors: Adrian John Carmichael, Mark Frost, Andrew Stuart Overend, Steven Burgess Tattum

Patent number: 8790543Abstract: A closure (40) for a container incorporates calcium hydride and a matrix material as a hydrogen-generating composition. In use, hydrogen is generated which reacts with oxygen permeating a container associated with the closure and a catalyst associated with the container catalyses reaction of the hydrogen and oxygen to produce water, thereby scavenging the oxygen. The composition of calcium hydride and matrix is also claimed.Type: GrantFiled: April 8, 2010Date of Patent: July 29, 2014Assignee: Colormatrix Holdings, Inc.Inventors: Adrian John Carmichael, Andrew Stuart Overend, Mark Rule, Ronald James Valus, James Stuart Leeming

Patent number: 8710128Abstract: Acetaldehyde production in a polyester may be reduced by using a formulation which comprises an acetaldehyde scavenger and a phosphorous additive. The two materials appear to act synergistically in reducing acetaldehyde production. Preferred formulations comprise anthranilamide and phosphorous acid and are used in combination with aluminium or titanium catalysed PET resins.Type: GrantFiled: February 12, 2010Date of Patent: April 29, 2014Assignee: Colormatrix Holdings, Inc.Inventors: Adrian John Carmichael, Carolyn Diana Adamson, Philip Brannon

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).

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
