<p>The wedge consists of two cradles (1, 2) with concave curved upper edges, connected by sides (5, 6) in hinged sections that fold inwards in the middle to reduce the dimensions of the wedge when not in use. The lower edges of the hinged sides have notches (7, 8) to accommodate reinforcing blocks (3, 4) on the cradles' inner surfaces when folded to avoid increasing the thickness of the wedge when stowed. The cradles's curved edges have different radii of curvature to hold containers at a slight angle for greater stability.</p> |
