Abstract: A device and a method for forming at least a liquid tight joint between two elements. Either or both elements have sealing portions, which in an area intended for abutment of the elements provide said joint when said elements are brought together in the abutment area. The sealing portion is formed as a seal which by being formed by sequential injection moulding technique is molecularly integral with an area directly adjacent to said seal. The injection moulding technique allows a choice of a relatively softer material for the sealing portion and a high degree of design freedom, including designs of high hygiene standards, especially well suited for aseptic or sterile packaging systems.

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.
