Abstract

Abstract A wrapper or sleeve-type package is disclosed for packaging, shipping and dispensing flat stacked articles in bulk such as envelopes. The package comprises an elongated construction having the same shape in cross section as the packaged articles, with foldably connected top, bottom and end panels and open side walls. The articles are retained in the package by short flap extensions which are foldably connected to the sides of the top, bottom and end panels. The end of these short flap extensions are adhered together to complete the package. Meanwhile, the package further includes a novel opening means incorporated into the top panel for dispensing the articles into an automatic inserting machine or the like.
