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;
A collasible carrier for articles and 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 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 component 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 fold folded fully and the horizontal lines 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 substantially horizontal cut being folded to reverse inwardly for forming separation for separating the upper parts of the articles carried and for accommodating a carrying opening and providing stiffness to the carrying opening upon folding and gluing the blank into a collapsed collapsible carrier which blank is dimensioned for erecting into a carrier for use.
