Patent ID: 6942118

Claim:
A closure arrangement comprising a base component defining a closable opening, a closure for said opening and hinged to said base component for movement between closed and open positions, a catch mechanism for maintaining said closure in said closed position, juxtaposed lugs provided respectively on said base component and said closure in the region of the hinging axis of said closure, each lug having at or adjacent its free end a receptor, and an elastic link locate in and extending between said receptors of said lugs, said receptors of said lugs being off-set from the hinging axis of said closure and in a spaced apart relationship parallel to the direction of said hinging axis, said receptors of said lugs being arranged such that said elastic link is stretched when said closure is at its closed position, the straining of said elastic link varying as said closure is moved between its closed and open positions and is least when said closure is at its open position wherein said variation in strain moves said closure from said closed position to said open position upon release of said catch mechanism and wherein said base component forms a part of a lid assembly for a container.
