摘要： A closure for releasably securing to a container adapted for storing foodstuff or a beverage, the closure comprising closing means (14) for closing a mouth of the container and securing means (22,23) for securing it in a closed position, the closing means and the securing means being formed of a plastics material comprising polyoxymethylene so as to provide a substantial gas barrier to the passage of oxygen and/or carbon dioxide therethrough, The closure may have a sealing member (18) formed of resilient material (compared to the rigid material of the remainder of the closure) for providing a seal between the closure and the container. The sealing member may be provided on a bore component which projects into the container so that, in use, it seals against an internal surface of the container. The sealing member may be an o-ring (18) formed of an elastomer, e.g. nitrile butadiene rubber. A foodstuff or beverage container, e.g. in the shape of a wine glass or the shape of a beer glass, having such a closure is also described. The use of a plastics material comprising polyoxymethylene for closing a container provides a barrier to the ingress of oxygen and/or to the egress of carbon dioxide to improve the shelf life of the product is also described.

摘要： A container and closure includes a closure secured to the container through projections comprising a series of horizontal, circumferentially spaced apart elements arranged so that the elements on the closure can pass though the spaces between the elements on the container and locate beneath them to secure the closure to the container. The elements of the projection on the container are separated from each other in the circumferential direction and do not overlap with each other in the vertical direction and the elements of the projection on the closure are separated from each other in the circumferential direction and do not overlap with each other in the vertical direction. The closure carries a sealing member for providing a seal with either an internal or external sealing surface of the container. The seal is driven down from a lead-in surface to engage the sealing surface as the closure is rotated.
