ABSTRACT:
Carton constructions for manufacture from corrugated sheets are disclosed. The constructions relate to the type wherein an automatic bottom is employed. When the carton is opened from its collapsed condition the bottom, which is interconnected, automatically deploys in a locked position. By use of particular dimensional arrangements for the bottom flaps, the usual tendency of such automatic bottom cartons to collapse once opened is eliminated as well as the problem of bridging in overlap configurations.
