Abstract
Abstract A box-shaped container has at its upper end an outwardly extending horizontal flange provided on one longitudinal side with at least two slots so as to form two hinge pins of substantial square cross section between each slot and the outer edge of the flange. The cover is provided along its longitudinal edge with two pairs of flaps, each pair comprising two oppositely disposed flap members which are curved toward each other and form a fork which partially embraces a hinge pin. A curved leaf spring extends along the outer surfaces of said flap members and is attached thereto with its inwardly bent ends which enter into slots in said flap members or engage shoulders on said flap members. The opposite longitudinal sides of the cover and box are locked together by a latch member which extends downwardly from a flange on the cover and lockingly engage the horizontal flange on the upper edge of the box.
