Abstract
A vending and reclosure device for powder and granular products. The device is formed of two container panels disposed in overlying relation with respect to each other with an inner one of the two panels having dispensing openings therethrough and the outer one of the panels having formed therein a closure flap which is normally initially free at one end and is connected to the outer panel along sides thereof by way of lines of weakening having projecting curved intermediate portions which, when ruptured permit the closure flap to be pivoted at a hinged end thereof out of the plane of the outer panel and away from overlying relation with respect to the dispensing openings in the inner panel. The inner panel is provided with cut lines generally aligned with the lines of weakness. When the closure flap is removed the lines of weakness define curved projections along the opposite sides thereof and the cut lines in the inner panel define shoulders behind which the projections can lock.
