However, the provision of what I term “gussets”, one at each of the eight corners of the blank, as indicated at ii of Figs. 5 Fig. '7. This act ordinarily is performed during the ?ap gluing operation of Fig. 4, wherein con and 7, effectively seals each of the eight corners sired. when the flaps are folded down and glued or when the glued side flaps are ?nally folded'in wardly upon the inwardly disposed end ?aps i4 and I5, as suggested by Figs. 6 and 8, the vari otherwise secured in place. The gussets, in e?ect, plug the corners of the container where the ?aps meet when folded over to close the top and bot tom thereof. ' ventional gluing means or glue rolls are indi cated at 21. The carton may also be ?lled simul taneously with the said gluing operation if de $1 ous gussets ii are naturally cramped at the 10 corners whereby to effectively plug or seal the ‘ The manner of forming the gussets may be as follows. (Referring to Figs. 1 and 9, i1 indicates part of any ordinary press or carton blank form ing machine, which carries knife elements and scoring elements I! and i9, respectively, properly arranged to blank out the carton of Fig. 'l and to provide the various scores 20 and slits 2|. The machine in general may be of any approved type, and it ordinarily includes a reciprocating bed 22 adapted to carry one or more frames 23 in which are clamped a series of carton blanking units comprising the scoring means and cutters above referred to. In practice, a large sheet of cardboard or paper is fed onto the frame to overlie the elements i8 and i8, and ‘this sheet' moves, with the bed and frame, beneath a pres sure means 24 which forces the sheet against the cutters and scoring elements to provide the blank disclosed in Fig. 7. Particular attention is directed to the trans verse cutters or blades II which provide the slits 2| of Fig. 7. It will be noted that each blade is ground or shaped at one end, as at 25, to slope toward the major axis of the blade, so that any slit 2| formed by the blade will be incomplete at the adjacent longitudinal score 20, especially as corners against entry of moisture, air, etc. The _ cardboard or paper stock for the cartons or con taines is invariably made up of thin layes of paper, wherefore the gussets when formed are constituted of a de?nite amount of stock deter mined by the shape of the blade ends 25 and the depth of the cut with which such blades enter the stock. The blades therefore must be properly adjused, as to height, within the frame 23 of Fig. 1, or else the compressive force of. roll 2| should be varied to secure the result above set forth. The various steps of the method of forming the cartons is as follows: After setting up the machine of Fig. 1 to effect the proper scoring, cutting and blanking out operations, the table with a sheet of cardboard thereon is reciprocated relative to the compression means 24, whereby to produce the various scores and incomplete 30 slits shown in Fig. 7. The blank thus formed is then glued along its extended glue ‘flap 28 and shaped into a rectangular open ended tube with said ?ap glued to the wall 29. Thereafter, the bottom~forming ?aps are bent along their score lines, providing gussets as explained, and secured to one another to close the bottom of the con talner. The next operation is the ?lling and The exterior surface will be entered by the inclined gluing operation ofFlg. 4, which has been ex plained. Upon closing the top of the ?lled con 40 portion 25 of the blade, to an extent that varies in depth from approximately zero to the'thlck ‘ tainer by turning inwardly the end ?aps i4 and i8 and the side flaps i2 and IS, the gussets at ness of the cardboard. In other words, the ex treme sharpened end or corner 28 of the blade is the corners or meeting points of said ?aps are adapted to enter the outer surface of the blank securely cramped between the flaps to eifectively at the adjacent longitudinal score 20, or may seal and plug said corners. The gussets obvi stop short of cutting or slitting contact with the ou'sly are bound to provide a tight seal because blank, whereby the portion oi the blade adjacent they are thin and more ?exible than the carton the end 26 thereof, produces a channel or groove stock, thereby insuring the formation of. plugs which progressively extends deeper into the blank which do not materially resist the closing force as the groove or channel extends in alignment of the folded-‘over ?aps. . Upon completion of the carton or package, a with the slit and toward the free ends of. the flaps such as l2, i2, i4 and I! and the groove coating of suitable lacquer or other elastic adhe or channel then merges with that portion of the sive and cohesive substance may be sprayed, cut or slit that‘ severs or divides the free ends of brushed or otherwise applied to the various I regards the interior surface of the blank. adjacent flaps. The carton body, comprising walls 29, 40, ll, 42, and 28, when formed and secured as is common practice, provides a hol low receptacle having the indicated ?aps dis joints,‘ if desired.
