ABSTRACT:
A container closure of the so-called spout type comprises a female element and a male element. The female element is attachable to a flexible container wall section, and the male element is attachable to an opposite wall portion, such that a container, for instance a four sided edge sealed pouch of the giant size type, is closable by arranging the female element and the male element in a sealing engagement for forming a closure. An axially operating arrangement for providing relative axial movement between the male and female elements, for instance of the bayonet type is arranged for providing an axial or relative movement of the female and male elements, such that an axial sealing ring will be compressed. The sealing of such ring may be supplemented by the sealing effect obtained by means of the ribs and grooves of the device. As a further specific feature the seal may include bacteria killing material, for instance of the ZEOLIT-type. According to a further aspect of this invention a device is sealed gas and vapour tight, against the female element and forms a barrier layer, such that a buffert space is formed between the barrier layer and the male element, said buffert space being highly sterilizable, for instance by gamma radiation, together with the rest of the container.
