-PATENT OFFICE CARTON Bruce J. Davidson, Kew GardensQN'. Y., assigner `to National Biscuit Company, New York, N. Y., a corporation of New Jersey Application. December 30, 1931, Serial No. 583,855 26 Claims. (Cl. 229-51) cereals, confections,'soap powders, drug supplies,

cigarettes, and many other articles that are put up in sealed packages by the manufacturer and are sold to the ultimate consumer in their original containers. l

Heretofore it has been the usual practice to seal the cartons tightly at the factory, and theycould be opened by the consumer only by tearing away a part ofthe package. In many instances the consumer does not use the entire contents of the package at once, and, if the package has been torn, it cannot be reclosed satisfactorily. Therefore, one of the objects of my present invention is to produce a carton that can be sealed tightly by the manufacturer when it is filled, and yet be constructed so that it can be opened by the consumer without destroying the carton-and can be reclosed easily and securely until some of its contents are'want'ed again.

Another object is to produce a carton that can be glued or otherwise securely sealed at the factory, and yet can be opened and reclosed repeatedly without breaking any part of the original glued closure and without the use of adhesives in that is adapted to be inserted within the carton to close it along the severed line when the carton is reclosed.

Another object of my invention is to produce a carton of the kind referred to wherein all ofthe outer panels, ends and sides terminate at the respective edges of the box, so that the outside ofthe box is smooth or h as no interrupted surfaces, and therefore-may be satisfactorily enclosed c in an outer wrapper if desired.

The above and other objects and advantages will be understood by those skilled in the art reference being now made to the accompanying drawings wherein I haveillustratedsome practicable embodiments of my invention and wherein- Fig. 1 shows the blank from which one form of carton embodying my invention may be formed, Fig. 2 shows the carton sealed at the side and folded flat as it is made at the carton factory ready to be shipped to the manufacturer to be filled and sealed at the ends',

Fig. 3 shows the carton after it has been opened by the consumer and also shows the tuck that is adapted to close the carton valong the severedY line, Y

Fig. 4 shows a blank from which another carton embodying my invention may be f ormed,

and I1, and slits or cuts I8, I9, 20, and 2|, whichA define a front panel 22, a bottom panel 23, .a rear panel 24, a top panel 25, and tuck 26, extending in succession from one end to the other-'of the blank. The score lines I6 and I1, and the cuts I8 to 2| define flaps 21, 28, 29, and 30 at the ends of the front and rear panels 22, and 24, and at the ends of the bottom panel 23 provide theA two end panels 3| and V32, the Width of these two end panels'being equal to the width of the nished carton, and their length equal to the` height of the box. v f

'I'he material of the blankextends beyond these two end panels to provide iaps 33, and 3l, which may be bent inwardly when the box is formed along the score lines 35, 36. The front panel 22 vis alsoprovide'd with a weakened, or tear line 31, the ends of which terminate substantially .at

the upper corners of the front panel and which bends inwardly so that it is normally a suiiicient distance inward from the edge of the front panel to provide a strip 38, that may be glued or otherwise secured to the tuck 26 when vthe box is assembled, the tuck 26 being wider than this glue strip.

After the blankhas been cut out, scored and l secure the blank'in box forming position. This style' of carton is adapted to be lled through the end, the manufacturer rst straightening the carton of Fig. 2 into box form and then-lling it through the end before the end llaps 'and end panels are secured in position.

When the box is filled and sealed, the flaps 33, 34 extend inwardly under the cover 25 and the tuck 26 liesinside of the front panel 22. the consumer desires to open the package, lhe uses his thumb nail, or a blunt instrument, to break the package along the tear-'line 31, which is just below the glued surface of the front panel at the top of the tuck 26. This enables the purchaser to raise the top, as shown in Fig. 3, to open the box, and when it is desired to reclose it after using part' of its contents, the tuck 26 is again inserted inside of the front panel 22, which successfully closes the box. 1f desired, the flaps 33, 34 may be very lightly glued to the top 25 so that they will readilybreak loose when the top is lifted.

In practice it has 4sometimes been found desirable to have the tuck 26 on the outside of the box and overlapping the tear line 31. When this is done, the front panel has a short glue flap that is glued to the underside of the cover. To open the box, the tuck is raised to disclose the tear line. 31, which is then broken, and the box opened by raising the tuck and cover. To reclose the box, the tuck is'inserted inside of the front panel.

The form of carton box in Figs. 4 to 8 is formed from the blank of Fig. 4, wherein the front panel 39, a bottom panel 40, a rear panel 4|, a top 42, and a tuck 43 are formed in succession, being separated by score lines on which the blank is folded to form the box.

The front panel 39 has flaps 44, 45 formed at l each end, these flaps being substantially the full size of the end of the box. A weakened or tear line 46 extends across the front panel and the two end aps, terminating near the upper corners of the flaps, and its distance from the edge ofthe front panel being sufficient to provide a glue strip-41. The bottomipanel 40 has aflap 48, 49 at each end and the rear panel 4| has an end panel 50, 5| at each end, these end panels preferably being of the same size as the end of the' llnished carton. Thetop 42 has two end ilaps 52, 53, to which the flaps 44 and 45 are secured when the box is completed.

Fig. 5 shows the carton as it is partly assembled at the carton factory for shipment to the manufacturer. This carton is adapted to be lled from the end, and Fig. 6 shows the carton after it has been lled and is in process of being sealed. It will be noted that the tuck 43 lies inside of the front panel 39, and that theend panels 50,.5,| are inside of the other aps. The flaps 48, 49, 52, and 53 lie next to the ends 50, 5|, but are not glued thereto. The last operation in sealing the carton consists in applying an adhesive to the the box after it has lon the front panel 39 extends across the front of the box just below where it is glued to the upper part of the tuck e3. I have shown this tuck 43 as being oi' greater width than the glue strip 41, but this is for purpose of illustration only, and in many instances this form of my invention will have the width of the tuck equal to or less than When' the width of the glue strip 41. when it is desired to open the box,` the consumer will break it along the tear line 46, which releases the top and permits it to be opened as .shown in Fig. 8. 'Ille carton obviously can be opened andreclosed as many times as the purchaser may find it necessary.

The blank of Fig. 9 has av front' panel 54, bot-- tom panel 55, rear panel 56, top 51, and tuck 58 dened thereon by score lines,.and at the sides has the flaps 59, 60, 6|, and 62, and the end panels 63,64, 65, and 66.V The end panelsand iiaps 60 to 64 are defined by the score lines 61, 68, and the end panels 65, 66 by the tear lines 69, 10.. The.

front panel 54 has a tear line '1|, which is spaced from its edge a sucient distance to provide a glue strip 12 which, when the carton is'form'ed, is secured to the tuck 53. It will be noted that the ilaps 59 to 62 are cut away slightlyl at their top 65, 66 fixed over them., The adhesive is applied' to the four flaps 59, 60, 6| and 6 2, which are then turned in and not only glued together, but the inner one glued to the adjacent end or 66, as the case may be.' When the carton is filled and closed, the tear strips 69, 10 will be at the top of the box, .and the cut-away portions of the flaps 59 to 62 will permit access to these weakened lines. To open the box, the consumer breaks it along`the lines 69, 10, and 1| with his ,finger nail, or any other suitableinstrument, after which the cov/er can be raised as illustrated in.Fig`. 11.

y It will .be noted in Figs. `1 to 3 and 9fto 11 that the tear lines 31 and 1| donot extend the full length of the box, and that their endsbend upwardly to the edge of the panel on which they are located and terminate substantially at or a short distance from the upperrcorners of the box so as to provide lips as indicated at 31' in Figs, l and 3 and at 1| in Figs. 9 to l1. The lips 3|', 1| bind upon the ilaps 26, 5 8, when the box is reclosed, and hold the flaps in place. This is true because the cartons are made with the panels 23, 25 alike in width, as are also the' panels 55, 51, so that when the aps are inserted within the carton they exert some pressure on the respec tive front panels 22, 54. If the tear lines extended all the way across the front panels, then there would be no binding action on the flaps when the boxes' were reclosed. While I have shown and described three forms of carton in which my invention may be embodied, it is to be understood that these are butl illustrative of the invention and that the invention may be embodied in many other modications, and is not to be in my claims.
