ABSTRACT:
A one-piece paperboard container and closure member telescopically opens and closes and, in the process of opening, reveals hidden matter printed on the container body portion, the closure member automatically frictionally locking onto the container body portion in the closed position. A single paperboard blank has a first and second set of four serially connected rectangular panels, a corresponding set of connecting strips connecting the first and second set of panels and cooperating therewith to provide a top for the closure member and to provide telescopic movement of the closure member relative to the container body portion, a series of proportionately sized V-cuts between each of the first set of panels, just below and adjacent to the strips, and two pairs of converging cut score lines and a central perforated score line at non-adjacent corners of the constructed container body portion, the converging cut score lines having a predetermined height less than the height of the closure member.
