Abstract
A closure for a container is formed by a plastic body part and a plastic closure part connected by a thin, integral section which forms a 'score' line of easy tearability. The closure part has an annular wall slightly smaller than an annular wall of the body part. The score line is adjacent the bottom of the annular wall of the closure part and the top of the annular wall of the body part. Thus after the plastic has been torn along the score line, the annular wall of the closure part slips within the annular wall of the body part to form a reusable closure. The annular wall of the closure part and the annular wall of the body part have conformations that interlock when the two parts are so slipped together to releasably hold the closure part in place.
