Reclosable paperboard carton

A reclosable carton comprising

• a carton body having four walls and a bottom and defining an opening into an interior compartment defined between the walls, the walls and bottom comprising respective portions of a folded piece of paperboard;
• a carton lid having flanges that overlap upper portions of at least two of the walls of the carton body with the lid in a closed position;
• and
• a carton closure comprising a body closure portion adhered to an outer surface of an upper portion of one of the carton body walls as a first adhesive-backed label, and a lid closure portion adhered to an inner surface of one of the carton lid flanges as a second adhesive-backed label, the lid closure portion arranged to overlap the body closure portion with the lid in its closed position;
• wherein each of the body and lid closure portions has an exposed surface defining a series of tapered ridges spaced apart in the box lid closing direction, the body and closure portions positioned to slidingly engage in a ratcheting manner in which a tapered ridge of the series defined by the exposed surface of the lid sequentially engages multiple ridges of the body closure portion as the lid is closed, to hold the lid in its closed position;
• wherein the ridges of the body and lid closure portions are each formed of thermoplastic resin and each ridge comprises a row of multiple engageable elements integrally molded with and extending outwardly from one side of an associated sheet-form base, each element comprising a wedge-shaped scallop having an engageable side and a non-engageable side conterminous at a curved upper edge of the element;
• and
• wherein the carton closure is configured to be released by a closure separation motion normal to the carton lid flange inner surface, to separate the engaged ridges of the body and lid closure portions.
