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, catalyzed 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.

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.

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.
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.

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.

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.

A method for additive delivery during a plastics processing is disclosed. The method includes establishing a network of components in a control loop that uses a feedback method to drive at least one pump (46), thus enabling continuous, robust proportioning of additive in a difficult to control environment. The feedback method includes sending at least one signal from at least one sensor associated with a plastics melting machine to a controller (43), sending one or more signals from the controller to the at least one pump (46), monitoring the pressure in the at least one pump (46) and sensing the position of an injection nozzle valve (49), and sending one or more signals to the injection nozzle valve (49) instructing the valve (49) to open or close.
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.
A formulation for foaming a thermoplastic polymer, for example PVC, comprises a carrier, exothermic and endothermic chemical blowing agents and 1 wt%, preferably less than 0.2 wt% of water. The liquid formulation can readily be used for foaming PVC and other thermoplastics.

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.
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. Thereafter, a reaction between the hydrogen and oxygen takes place, catalysed by a catalyst associated with the container thereby to scavenge the oxygen.

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.

Polymer compositions, for example of polyethyleneterephthalate bottles or preforms, include a reheat additive which has reducing transmission/increasing absorbance across the IR region as the wavelength increases. The reheat additive may be a titanium nitride, made by a plasma vapor deposition technique. Advantageously, the material may be used at a lower level than hitherto known materials or may be used at the same levels as hitherto but provide a greater reheat effect. Example 3a shown in the figure illustrates the absorbance of a preferred material.
