Abstract: A method for closing and/or sealing an open top container without subjecting the container to objectionable axial compressive forces. A closure having a skirt which forms a downwardly opening annular recess or groove and having a bead at the end of the skirt, is constrained against movement while the mouth of the container is moved upwardly into the groove. An inwardly acting compressive force then crimps the closure against the neck of the container, either by embedding the bead in the wall of the container or by gripping the wall of the container above the closure bead or by both. One form of apparatus for carrying out the method is illustrated in the drawings.
