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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
169 words
A container including a body having a neck finish, said neck finish being integral with and of the same material as said container, said neck finish being of a predetermined original nondeformed exterior configuration, permanently deformed indentation means in portions of said neck finish exterior for engaging a closure, said neck finish being defined by upwardly, outwardly and downwardly directed wall portions relative to said body with said downwardly directed wall portion carrying said indentation means, a closure having a relatively rigid peripheral skirt of an internal diameter less than a predetermined maximum diameter of said downwardly directed wall portion whereby said downwardly directed wall portion is deflected inwardly by said closure peripheral skirt to a diameter less than said predetermined meximum diameter thus increasing the frictional purchase between contacting surface portions of said peripheral skirt and said downwardly directed wall portion and thereby forming said permanently deformed means, and said closure peripheral skirt terminates in an inwardly upwardly and outwardly directed curl which forms said permanently deformed means.
Claim 2
Dependent Claim
169 words
A container including a body having a neck finish, said neck finish being integral with and of the same material as said container, said neck finish being of a predetermined original nondeformed exterior configuration, permanently deformed indentation means in portions of said neck finish exterior for engaging a closure, said neck finish being defined by upwardly, outwardly and downwardly directed wall portions relative to said body with said downwardly directed wall portion carrying said indentation means, a closure having a relatively rigid peripheral skirt of an internal diameter less than a predetermined maximum diameter of said downwardly directed wall portion whereby said downwardly directed wall portion is deflected inwardly by said closure peripheral skirt to a diameter less than said predetermined meximum diameter thus increasing the frictional purchase between contacting surface portions of said peripheral skirt and said downwardly directed wall portion and thereby forming said permanently deformed means, and said closure peripheral skirt terminates in an inwardly upwardly and outwardly directed curl which forms said permanently deformed means.
Claim 3
Dependent Claim
208 words
A container including a body having a neck finish, said neck finish being integral with and of the same material as said container, said neck finish being of a predetermined original nondeformed exterior configuration, permanently deformed indentation means in portions of said neck finish exterior for engaging a closure, said neck finish being defined by upwardly, outwardly and downwardly directed wall portions relative to said body with said downwardly directed wall portion carrying said indentation means, said downwardly directed wall portion has a downwardly opening slot formed therein and opens through a lowermost peripheral edge thereof for providing an access area for a person''s fingers to facilitate the removal of a closure from said container body, a closure having a relatively rigid peripheral skirt of an internal diameter less than a predetermined maximum diameter of said downwardly directed wall portion whereby said downwardly directed wall portion is deflected inwardly by said closure peripheral skirt to a diameter less than said predetermined maximum diameter thus increasing the frictional purchase between contacting surface portions of said peripheral skirt and said downwardly directed wall portion and thereby forming said permanently deformed means, said closure peripheral skirt terminates in an inwardly upwardly and outwardly directed curl which forms said permanently deformed means.
Claim 4
Dependent Claim
