A carton has a keel structure (K) of rectangular cross section to separate adjacent rows of articles and to retain articles in position. The box keel structure carries a locking tab (38) which is caused to ride over and engage against a ridge (40) formed in an adjacent panel of the carton when the keel is set up from a collapsed to an upright position to maintain the keel upright.
