Abstract
Abstract A hinge structure for a round cover member adapted to be utilized on a rounded base member in a manner such that the cover can be nested partially around the base and removed from the base only when the cover is in a substantially open position. The flange, forming part of the hinge, has an open slot disposed at a pre-determined angle and rests on a post member which is disposed on each side of the base and off-center to serve the dual function of positive opening and closing of the cover with retention of the cover through the inability of the flange to pass over the extended sidewall of the rounded base.

Total Claims: 9
Claim 1
Independent Claim
181 words
A hinge structure for a rounded base and cover member providing free retention of said cover member and partial nesting of said cover member around said base comprising two oppositely disposed support members mounted externally on said rounded base member, two oppositely disposed flange members extending from said cover member, an open slot provided in each flange, said slot constructed and arranged to engage said support member and to rest on the end wall surface of said slot, said rounded cover member being of a substantially larger diameter than said base member so as to permit a portion of said rounded cover member to encompass a portion of said rounded base member, said support members being comprised of post members positioned off center on said rounded base member and said open slot in said flanges is disposed at an angle to direct said flange toward an extending sidewall of said base member except when said cover is in a substantially open position whereby said cover is captively retained on said base except when said cover is in a substantial open position.
