Abstract

There is provided a space divider which is made from a blank by a process in which various panels and tabs are defined by score lines and lines of severing, and in which the automatic machine which makes the space divider from the blank need only fold outer portions of the blank inwardly, and does not have to go through a zig-zag or fold-back operation. This means that a simpler mechanism can be utilized. There is also provided a space divider which utilizes less material than conventional space dividers, and which can be made of a depth less than the total depth of a carton while still being utilized both for the shipping of inverted empty bottles, and for the shipment of filled upright bottles. This is accomplished through the provision of registering fingers on the space divider, and a pair of apertures in the side walls of the carton, with which the fingers may alternatively register.
