Abstract

A carton includes a pivoting, reclosable lid that allows a top end of the carton to be accessed and subsequently closed. If a bag or other flexible vessel is accommodated within the carton, a first section of the lid can be pivoted toward a first side panel so that the vessel is pressed between the first lid section and the first side panel. The bag contents are thereby securely retained within the carton.
