Abstract

Abstract A mailer for a flat object such as a book or the like consists of a base panel having first and second cell forming panels foldably connected to each other and to opposite edges of the base panel together with closure panels foldably connected to the cell forming panels which when secured in lapping relationship define a flattened tube. End closure flaps are foldably connected to the base panel and also to the closure panels and having converging side elements at the ends thereof which register with each other when the base panel and the overlapped closure panels are separated from each other and folded into lapping relationship, the cell forming panels during such separation adopting a transverse sectional configuration corresponding to the converging side elements of the closure flaps.
