Abstract
Abstract A cap type closure for a container of the type having a depending cylindrical flange surrounding the neck of the container is further provided with a locking ring disposed adjacent the lower edge of the flange which when disposed in smooth external alignment with the outer surface of the cap will provide an interfering engagement with a flange on the neck of the container to prevent axially directed movement of the cap relative to the axis of the container neck. The locking ring or a portion thereof may be pivotally connected at one side to the flange whereby the ring may be eccentrically disposed relative to the cap flange to provide clearance with respect to the flange on the neck of the bottle to allow the removal of the cap. Alternatively, the annular ring may be mounted for transverse sliding movement on the flange of the cap to allow for shifting the ring from the locking position where it is aligned with the cap flange to an eccentric unlocked position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
95 words
A container having cover means, said container having a neck defining an opening into said container, said cover means having a circumferential flange extending about said neck, complementary fastening means on said cover means and said neck, locking ring means, pivot means for pivotally connecting said ring means on said cover flange for movement transversely relative to said neck and cover flange, complementary locking means on said neck whereby upon operative locking engagement of said locking ring means with said complementary locking means, manipulation of said fastening means to remove said cover means is prevented.
Claim 2
Dependent Claim
95 words
A container having cover means, said container having a neck defining an opening into said container, said cover means having a circumferential flange extending about said neck, complementary fastening means on said cover means and said neck, locking ring means, pivot means for pivotally connecting said ring means on said cover flange for movement transversely relative to said neck and cover flange, complementary locking means on said neck whereby upon operative locking engagement of said locking ring means with said complementary locking means, manipulation of said fastening means to remove said cover means is prevented.
Claim 3
Dependent Claim
118 words
A container as set forth in claim 1, wherein said locking ring means is comprised of an annular ring having a cylindrical external surface with the same radius as the radius of said cover flange and an internal surface disposed eccentrically relative thereto, said complementary locking means comprising an annular locking rib formed on said neck whereby when said cover means is secured in locked position on said neck the external surface of said annular locking ring will be flush with the external surface of said cover flange and a portion of the upper surface of said locking ring will be disposed below said locking rib to prevent axial movement of said cover means relative to said Neck.
Claim 4
Dependent Claim
108 words
A container as set forth in claim 1, wherein said locking ring means is comprised of an annular ring having an external cylindrical surface with a radius equal to the radius of the cover flange and having an internal surface eccentrically disposed relative thereto, an undercut notch being provided in the portion of said locking ring having the greatest radial dimension to define a locking tooth, said complementary locking means comprising a plurality of locking lugs formed on and protruding radially outwardly from said neck for engagement by said tooth when the external surface of said locking ring is flush with the external surface of said cover flange.
Claim 5
Dependent Claim
48 words
A container as set forth in claim 1, wherein said cover flange and said locking ring means are of integral one piece construction joined by narrow post means acting as a torsional pivot member normally maintaining said locking ring means and said cover flange in flush aligned relation.
Claim 6
Dependent Claim
40 words
A container as set forth in claim 5, wherein the complementary engaging faces of said locking tooth and said locking lugs are formed as arcs of a common circle whose center is concentric with the axis of said pivot means.
Claim 7
Dependent Claim
48 words
A container as set forth in claim 5, wherein the complementary engaging faces of said locking tooth and said locking lugs are formed as arcs of circles having the same radius but with the centers thereof being offset from each other to provide a snap action interference fit.
