(under subclass 592) Process including inwardly deforming the walls of an extant end portion of an article containing or material containing receptacle to decrease the size of the end opening and thereby prevent escape of contents of the receptacle.
(1) Note. In the patents here classified the "container" has a fixed, or more or less permanent, relationship with the material encapsulated rather than being merely a temporary or transient cover to form a package; for example, in this subclass may be found metal bottles for gas storage the claims reciting the association of the metal bottle with an absorbent material for holding the gases which association of metal cover and absorbent material is a permanent
relationship. The mere association of the metal bottle with the contained gases only, however, is an example of the type of transient association that is not provided for in this class but may be found in other appropriate classes. See the Search Notes below.
