A container () includes an oxygen-sensitive beverage, for example a vitamin C-containing beverage. A closure () seals the mouth () of container (). 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.

Scavenging oxygen

A reservoir assembly () comprises a container (), a support assembly () on which the container () is mounted and fixed and a rotary electric vibrator device () coupled to the support assembly (). The container holds a shear thinning additive for a plastics material. The reservoir assembly is arranged so that on operation of the device (), an appropriate frequency and amplitude of vibration is applied to the container () 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.

Delivering liquid additive

A food container () includes a rigid thermoformed plastics carton () which holds a dry foodand is closed by a removable film closure (). The film () incorporates a hydride which is arranged to generate hydrogen on contact with moisture. Additionally, the film () is arranged to have relatively high water vapour permeability and relatively low hydrogen gas permeability. In use, water vapour from air surrounding the container () passes into the film () and reacts with the hydride to generate hydrogen. Due to the relatively low hydrogen permeability of the film (), 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 (), thereby to scavenge oxygen within the container () and protect the food () from oxidation.

A polymer additive for improving the reheat characteristics of a polymer or polymeric composition comprises an inorganic material which is such that a 2.5 mm thick polyethylene terephthalate plaque incorporating the inorganic material has, when tested, an absorption ratio of less than 0.9, wherein the absorption ratio is either the ratio of A/Aor the ratio A/A, wherein:

Polymeric materials and additives therefor

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.

Polymer compositions and articles having improved reheat characteristics

A process for recycling a coloured thermoplastic material comprising an absorbed disperse dye comprises contacting the optionally comminuted coloured thermoplastic material with a caustic wash and recovering an at least partly colour-modified thermoplastic composition from the caustic wash.

Recycling

A part may be manufactured in a desired color from virgin or recycled polymeric material by selection of a color formulation to be used in a first location; relaying color information to a centralized match prediction systemas regards the desired color and other information concerning a polymeric material which is to be made in the desired color. The systemincludes a database and associated software and is able to take the color information and predict how to reproduce the colors using an associated color dispense system. A devicecontrols dispense stationsandwhich may be conveniently situated at customer sites or the like. The dispense stations dispense colors for use.

Polymeric materials

A polymer additive for improving the reheat characteristics of a polymer or polymeric composition comprises an inorganic material which is such that a 2.5 mm thick polyethylene terephthalate plaque incorporating the inorganic material has, when tested, an absorption ratio of less than 0.9, wherein the absorption ratio is either the ratio of A1/A2 or the ratio A1/A3, wherein: Preferred inorganic materials are titanium nitride, indium tin oxide and lanthanum hexaboride.
