Abstract
Abstract A carton construction having at least one open end for display of a tray contained therein, featuring a new end construction designed to hold the tray in place within the carton. The carton end construction includes a restraining panel, biased against a sidewall of the tray, hingedly connected to the bottom panel of the carton and extending inwardly of the carton, and two locking flaps hingedly connected to the side panels of the carton and extending inwardly of the carton. The end construction especially features a pair of engaging flaps extending laterally from the restraining panel. The locking flaps overlie the engaging flaps within the carton, thereby restricting lateral movement of the tray with respect to the restraining panel.
