A top member lies atop the planer surface and has a hinge defining the top member into two portions, one of which has structure for affixing it in face to face relationship with the planer surface on top of the base. The other portion is movable about the hinge from an orifice closing position atop the planer surface to an orifice open position extending at an angle to the planer surface. A flexible tongue extends into the area of the hinge and is capable of undergoing a snap movement from one side to the other of a raised rib in the planer surface to hold the second portion of the top in the orifice open position at an angle to the planer surface. The second portion of the top may be equipped with a stopper insertable into the orifice.
