Cuboid Collapsible Box Having a Center Web

Abstract

The invention relates to a cuboid collapsible box which comprises walls ( 1, 2, 3, 4 ) and a bottom closure, having bottom closure tabs ( 10, 12, 13, 14 ) and a center web configured by web areas ( 20, 21 ), and to a cut for said box. The aim of the invention is to provide a collapsible box whose center web is reliably protected from being displaced. For this purpose, retaining surfaces ( 18, 19 ) are provided on the lateral bottom closure tabs ( 10, 12 ) on the ends facing away from the lateral walls ( 1, 3 ). The front and the rear bottom closure tab ( 11, 13 ) have notched surfaces ( 26, 27 ) and the notched surfaces ( 26, 27 ) rest on the retaining surfaces ( 18, 19 ) from below and on the lateral bottom closure tabs ( 10, 12 ) from above.
