Abstract
This relates to a closure unit which may be inserted into an open end of a tubular container body, particularly one formed of paperboard or plastic material, and which will have an automatic interlock with the container body and a seal sufficient to hold the closure unit in sealed relation with respect to the container body under all normal usages without the use of adhesive. The interlock between the closure unit and the container body is in the form of a plurality of retaining lugs which are resiliently deflected when the closure unit and container body are assembled and which have a pressure engagement with the interior surface of the container body to form an interlock therewith.
