Abstract
A reclosable paperboard carton and blank therefor, which carton has overlapping and glued end panels closing one end thereof. Once the end panels are opened, they can be reclosed by inserting a straight distal edge of one of the panels under an arcuate tab defined in the interior of the other panel. Using a plain, straight distal edge on the insertable panel reduces paperboard waste and manufacturing costs since exterior locking tabs are eliminated and single knife cutting can be used. In one embodiment, the tab is defined by an arcuate cut line and two spaced perforated lines extending from the arcuate line to the distal edge of the panel. In a second embodiment, the tab is defined by a cut-out recess extending from the distal edge of the panel and having an arcuate bottom edge.
