Abstract
Abstract A wraparound carton with overlapping panels secured together by adjustable locking means to compensate for variations in the diameter of the articles to be wrapped. The locking arrangement comprises a locking tab struck from the outer lap panel and having a plurality of lateral projections along the side edges thereof so as to form wavy lines, and a locking aperture arranged in the underlying lap panel for receiving the locking tap therethrough and having side edges which converge toward the end edge of the associated lap panel. Also disclosed is a device for tightening the wrapper about the articles whereby the lap panels are pulled into overlapping relationship at a predetermined rate.
