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.
