Abstract
A knock-down folding carton is disclosed having a top closure and a bottom closure, shown with a top tab type closure and an automatic bottom, in which the sides are a plurality of sets of isosceles triangular members, half of which have their bases defining the top closure opening, and half of them having their bases defining the bottom. The top closure is oriented on a diagonal of the bottom closure as a result of the side wall configuration. Optionally, drop flaps can be employed on the top closure so that the only raw edge presented is at the end where the tab is inserted. In addition, a double bottom can be employed. While the configuration shown is primarily square in cross-section, other uniform cross-sections such as hexagonal, and octagonal are shown.
