Abstract
A reclosable dispenser package of thin flexible thermoformed plastic material and method of manufacture is disclosed, the package including a base with peripheral edges and a cover thermoformed from a sheet of plastic which includes a cover wall with a dispensing opening therein defined by an inner margin, peripheral edges which are joined to the peripheral edges of the base so that the cover is closed upon and substantially covers the base, and a tubular lid integrally hinged to the cover at a hinge line forming a portion of the inner margin. The tubular lid includes an upper lid wall, a lower wall, and a forward surface. The cover wall further includes an arresting platform on which the tubular lid rests when in its closed position. The tubular lid pivots around the hinge line to open and close the dispensing opening.
