ABSTRACT:
A packaging container is closed by using a double seam 152 to secure over the container body 70 a cover 74 of smaller diameter than is usual, creating a radial space 104 around the cover chuck wall 122 into which the body sidewall 72 is deformed to form a neck 76. The cover is initially placed on the body to form a sealable interface 142 therebetween, this interface being preserved throughout the seaming process. The body and/or the cover may be of plastics or metal or a laminated material. In an aseptic packaging process, a primary seal is created at the interface 142 under sterile conditions, seaming subsequently being carried out under non-sterile conditions.
