The disclosure relates to cartons with separaters which, where the articles to be separated are deep, comprise a lower arrangement of separaters according to the invention in co-operation with a higher arrangement of separaters of known form and supported from a stiff central separater according to the invention. The lower and upper separaters erect automatically when the carton walls are moved from the flat condition to the rectangular condition, the lower ones are extensions of the known Crash-bottom style and arranged to interact together according to the invention to erect the separater forming extensions for separating two or more articles such as glass bottles. The invention includes joining the two separate similar opposing structures associated with the known Crash-bottom to effectively form one bottom member fixed at its four sides and the invention extends from the flat blank, through a process for folding and gluing the flat blank, to apparatus erecting the carton and effecting joining of the bottom structures ready for the commercial use of the carton.

A collapsible carrier for articles constructed from a blank of sheet material including a bottom comprising bottom member panels depending from the bottom edges of each of four side walls by a horizontal line of fold, each side wall hinged by a line of vertical corner fold to the next side wall, and when the carrier is folded flat into the collapsed condition and assembled two of the four said vertical corner folds lie between the two other vertical corner folds which are folded fully each with members adjacent to it forming a similar opposing structure, the adjacent bottom member panels folded to lie against the inside of the adjacent side walls and a glue lap divided from one of the bottom member panels of each structure by a diagonal fold meeting with the vertical corner fold folded fully and the horizontal line of fold, the glue lap folded to lie against the adjacent bottom member panel and glued to it, at least one substantially horizontal cut above a said vertical corner fold and its adjacent side walls, the ends of the cut connecting with the lines of two vertical folds which have a further vertical fold therebetween and above the cut, one of said vertical folds providing another such vertical corner fold upon said further vertical fold forming an internal corner by reverse folding the carrier material, means including a second substantially horizontal cut located above at least one of said fully folded vertical corner folds with the carrier material above the second cut being folded to reverse inwardly for forming separation for separating the upper parts of the articles carried and for accommodating a carrying opening, when the carrier is erected; characterised in that the free edge of at least one bottom member panel of each one of said similar opposing structures carries a separater forming extension hinging with the bottom member at a line of weakness parallel with the said horizontal line of fold and the line of weakness dimensioned to communicate with a said line of weakness of the similar opposing structure when erected and the height of the separater extensions dimensioned to finish below the carrying opening of the inwardly reversing carrier material when the carrier is collapsed, said separaters each arranged and adapted for the transmission to it of opposition force through engagement between said separater and another said separater for their rightangular displacement relative to their said at least one bottom member panel when said at least one bottom member panel and the bottom member sharing a said diagonal fold together are displaced vertically by their respective side walls of their said similar opposing structure being displaced horizontally and said carrier material enabled to reverse inwardly is displaced inwardly contributing stiffness and positioned for co-operating with the separater forming extensions of the bottom which separate the lower parts of the same said articles carried in the erected collapsible carrier which is erected by moving each said fold for folding fully one toward the other and opened to provide the said displacements.
