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: 10053545Abstract: A method of introducing an additive into a polymeric material comprises using a liquid formulation comprising an additive, for example a colorant, and a vehicle comprising an aliphatic or aromatic tri- or di-carboxylic acid covalently linked by ester bonds to two or more chains. The method involves contacting the liquid formulation with the polymeric material in a melt processing apparatus. The cavity transfer mixer may be used in the process. A fiber is suitably subsequently produced.Type: GrantFiled: December 19, 2011Date of Patent: August 21, 2018Assignee: COLORMATRIX HOLDINGS, INC.Inventors: John Goulbourn, Andrew Stuart Overend, Christine Leeming

Patent number: 9611081Abstract: 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 vapor 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: GrantFiled: April 9, 2010Date of Patent: April 4, 2017Assignee: COLORMATRIX HOLDINGS, INC.Inventors: Ronald James Valus, Mark Rule, Andrew Stuart Overend, Christine Leeming, Steven Burgess Tattum, James Stuart Leeming

Patent number: 9550315Abstract: A reservoir assembly (40) comprises a container (4), a support assembly (42) on which the container (4) is mounted and fixed and a rotary electric vibrator device (44) coupled to the support assembly (42). The container holds a shear thinning additive for a plastics material. The reservoir assembly is arranged so that on operation of the device (44), an appropriate frequency and amplitude of vibration is applied to the container (4) and, therefore, its contents. As a result, a liquid dispersion in the container is shear thinned and recovery of dispersion from the container is increased.Type: GrantFiled: March 26, 2010Date of Patent: January 24, 2017Assignee: COLORMATRIX HOLDINGS, INC.Inventors: Brian Jones, Keith Bell, Andrew Stuart Overend, Mark Frost

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: 9139704Abstract: A method of introducing an additive, for example a dye, into a polymeric material comprises using a liquid formulation comprising the additive, a vehicle and an active compound added to increase the melt viscosity of the polymeric material. The active compound may be a multi-functional anhydride. The liquid formulation is suitably contacted with the polymeric material in a melt processing apparatus and suitably a cavity transfer mixer is used in the process. A fiber is suitably subsequently produced.Type: GrantFiled: December 19, 2011Date of Patent: September 22, 2015Assignee: COLORMATRIX HOLDINGS, INC.Inventors: John Goulbourn, Andrew Stuart Overend, Christine Leeming, James Leeming

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
