Abstract
The object of this invention is to provide a releasable hinge for swingable portions such as a cover and bottom of a container or the like. The releasable hinge comprises a pair of spaced apart, laterally flexible spring fingers projecting from one wall of one portion of the container into a blind notch on an opposed wall of another portion of the container. The side surfaces of the notch are arranged and spaced to flex the fingers together until lateral porjections at the ends thereof nest into complimentary recesses in the side surfaces for hingedly coupling the container portions together. When the container portions are rotated about the projections to a maximum open position of the container, back surfaces on the fingers engage and pivot about the blind end of the notch. Further open movement of the container portions causes the projections to be forced out of the recesses for releasing the hinge and preventing damage to the hinge and/or container portions.
