Container and closure combination

Abstract

Abstract This disclosure relates to a container of thermoformed plastic material having a metallic closure, the closure being of a conventional construction and including a channel terminating in a relatively rigid peripheral skirt, the container having a body terminating at an upper end portion in a bead having a peripheral skirt normally disposed upon the upper end portion of the container body, and the peripheral skirt of the closure being of an internal diameter less than the predetermined maximum diameter of the container peripheral skirt whereby the container body peripheral skirt is deflected inwardly by the closure peripheral skirt to a diameter less than the predetermined maximum diameter thus increasing the firctional purchase between contacting surface portions of the peripheral skirt due to the inherent tendency of the resilient container peripheral skirt to rebound radially outwardly toward its predetermined maximum diameter. In addition, the container peripheral skirt includes an exterior surface formed with circumferentially spaced axially extending lands and valleys, and being constructed from pressure-deformable material whereby the lands are depressed at the contacting surface portions of the skirts as the container peripheral skirt rebounds toward its normal position thus producing a ''''selfthreading'''' or ''''self-locking'''' feature of the invention.
