Abstract:

An improved carton having, in preferred form, a break-away partition fixed between opposed side walls of the carton when the carton is initially erected into a use position from a collapsed position. The break-away partition comprises a transverse stop-rib fixed to opposite side walls at the closed end of the carton, and a cushion flap hingedly connected to one side wall only and connected in break-away fashion to the stop-rib. When an article is inserted into the open end of the erected but unfilled carton, the insertion step causes the cushion flap to break-away from the stop-rib at the carton's closed end. This allows the support rib to function as a seat for one end of the article, and this also deforms the cushion flap only as required so as to enhance the cushioning characteristic of that flap for the sides of the article, when the article is fully located in the carton.
