Abstract
A dispensing closure with a hinged flap for conveniently opening and closing a dispensing aperture. The closure is a one-piece molded part having an integral living hinge. A mechanism for releasably locking the flap in a stay-open position and thereby resisting any tendency of the hinge to resiliently bias the flap towards a closed position is provided. The stay-open mechanism comprises a cooperating pair of surfaces molded into the flap and main body of the closure which are arranged to snap into and out of locking engagement when the flap is deliberately moved into or out of the open position.
