CARRIER CARTONS FiIed April 10, 1953 2 Sheets-Sheet 2 United States Patent CARRIER cARToNs Charles L. Champlin and Gerald H. Steele, Rittman, Ohio, assignors to The Ohio Boxboard Company, Rittrnan, Ohio, a corporation of Ohio Application April 10, 1953, Serial No. 347,984 8 Claims. (Cl. 220-405) In, the provision of the so-ealled slit-package" of articles, such, primarily, as canned beer, it has become more or less accepted practice to assemble. the six cans, on end, in two rows of three cans, each, in a paperboard carton or container, and one object of the, present invention is to provide a carton or container pretierably of; pen top fo m a ha ng a handle memb r ex endin l ngi u n lly f h ca to b tween the two. r ws of cans. This handle member is provided with ahand, hole and is vertically shiftable with respect to the end walls, of

he carton an h ow of cans, where y when. it s n.

its lowered or p ssed posi ion i s. top ed w l be. substantially in a plane with the tops of the cans, and when it is raised will extend above the tops of the cans in such position that the hand hole will be accessible for carrying the package.

A further object of the invention is to provide a carton or container of this general type having multiple ply end Walls with the inner, oppositely disposed, plies of these two walls provided with medial slots, andv the handle member provided at its, opposite ends with laterally oil'- standing wings which, when the handle member is assembled in the carton, will extend into the spaces be-. tween the inner and outer plies of the end walls, the wing members being of considerably less height than the end walls to thus permit the handle member to be raised and lowered while guided by the slots of the inner plies of the end walls, and the wing members serving to arrest any raising of the handle member by their engagement with the folds at the top edges of the end walls where the inner and outer plies of such walls are joined, I

Still another obieot of the invention is to provide a carton structure of this type which willbe strong and satisfactory in service for the reason that the ultimate association of the wing; members of the handle member with the end walls is normally incapable of disengagement and is therefore wholly dependable. Moreover, the carton of the invention lends itself readily to assembly by automatic machinery, particularly when such maohinery forms a part of the line packaging apparatus now widely employed in breweries. 7

Itis to be noted, moreover, that, due to its form and arrangement in the carton, the handle member may serve also as a partition to separate the rows of cans or other articles.

With these and other objects in view, the invention, in a specific aspect, resides in providing the inner plies of the end walls or the carton orcontainer, at points flanking the handle receiving slots, withears which extend nearer to the carton bottom than the heightofthe wing members of the handle member when the latter are in the position determined by the greatest depression of the handle member within the carton, and thus lying behind such wing members when the handle member is initially lowered into the carton; and in providing, in substantially horizontal alignment with such ears apertures in the outer layers or plies of the end wall members through which probe means may be introduced to deflect or distort the ears inwardly and cause them. to snap over the upper edges of the wing members to time cause introduction of the, wing members between the In the accompanying drawings illustrating the invention, in the several figures of which like parts are simi-.. larly designated,

. the outer plies 7 ofthe-endwill members are p ovidcd with apertures 18 which, when the plies are in set-up,

folded condition, will be in substantial alignment with the ears 17.

The end flaps 4 of the side wall members 2 are provided with apertures 19, and their end edges are formed with arcuate recesses 20, these apertures and recesses serving to provide free passages between the apertures 18 of the outer plies 7 of the end wall members and the ears 17 of the inner plies 9 thereof when the carton is assembled.

Having reference to Figs. 2 to 4, it will be seen that the handle member is formed from a blank of suitable paperboard material, preferably of a nature and caliper adequate to give it desired strength and rigidity, provided with cuts and scores defining the main panel 21 and two similar

auxiliary panels

22 and 23 definedfrom the main panel by

folding scores

24 and 25, respectively. Otfstanding from both lateral edges of the

panels

21 and 23, and defined therefrom by folding scores 26, and of substantially equal area above and below the score 25 between these panels, are wing members 27 and 2S, respectively, and either one of the wing members of these pairs may have its lower outer corner relieved by an arcuate cut 29 for ease in separating the wing members of the pairs when folded together, as shown in Fig. 3, for a purpose hereinafter appearing.

The main panel 21 and auxiliary panel 22 are provided with cuts 30 and scores 31 defining reinforced hand holes, and these hand holes thus defined will register when the member is folded as shown in Fig. 3. When the member is thus folded the

auxiliary panels

22 and 23 will be secured to the main panel 21 throughout all their area with the exception of the

wing members

27 and 28, and preferably also the reinforcing members within the hand holes defined by the cuts 30 and scores 31.

In erecting the carton blank of Fig. l with its parts in proper assembled, set-up condition, automatic machinery may be employed, but whether such machinery is used or the carton is set up by hand manipulation, the following steps are performed, preferably in the order given.

Assuming that the carton is set up on automatic machinery, say of the forming die cavity and plunger type, the blanks (Fig. 1) preferably in a hopper in multiple, substantially vertical, arrangement and thus supported adjacent to the die cavity by rails with which the arcuate recesses 20 of the upper two of the longitudinally pposite end flaps 4 are engaged, are fed, as by a suction-cup feeding mechanism, one at a time, to a position over the forming die cavity and gauged in proper register therewith. Then, as the plunger descends, the side wall members 2 are brought up Upon the folding scores 3 to position substantially normal to the bottom member 1, their end flaps 4 meanwhile being progressively turned inward over the bottom member and overlapped, as shown in Fig. 6, in substantial vertical alignment with the folding scores 8 at opposite ends of the bottom member. Also, during the erection of the side wall members, and the folding of their end flaps 4, the outer end wall plies 7 are folded upwardly upon their folding scores 8 into face-to-face engagement with the in-folded end flaps 4, and thereafter the outer end Wall plies 9 are folded downwardly upon their folding scores 10, over the end flaps 4, their retaining flaps 11 are engaged with and beneath the locking flaps or tabs 14, and the set-up thus fully effected, as shown in Figs. 5, 7 and 8.

It will be noted that with the carton set up, as shown in Figs. to 11, and particularly in Fig. 6, the openings or

apertures

18 and 19 in the outer plies 7 of the end wall members and the end flaps 4, respectively, register, and that where the overlapping ends of these end flaps 4 extend into that portion of the end wall area where these registering apertures are located the arcuate recesses 20 in the edge portions of these flaps serve to clear these apertures. Thus, these arcuate recesses serve not only as a means to provide support of the carton blanks for feeding to the setting-up machine, but to afiord clearance at the registering

apertures

18 and 19 while, nevertheless, making it possible to have the end flaps 4 of such length that they may overlap, as has been found most desirable.

Moreover (and this feature is of broad application in cartons formed from this general type of blank), the shape and extent of the recesses 20 facilitates the automatic erection of the carton in that, even with no exact timing of the relative folding of the flaps 4 as they are brought into overlapped relation, there will be no tendency for the end edges of the respective flaps to catch upon or jam against each other, and they will readily slide one upon the other and be guided by the arcuate recesses into desired overlapping position even though their free corners may oppositely overlie and underlie one another, for, as will be seen in Fig. 6, and also in Figs. 7, l0 and 11, the recesses are sufficiently deep to provide a clearance at a between them at their maximum depth. It will be noted, furthermore, that the length of the flaps 4 is such that they are too short to permit the lower corner of one to catch in the aperture 19 of the other when they are inwardly folded and are brought, relatively, into juxtaposition as the side wall members 2 are folded upwardly.

In assembling the handle member of Figs. 2 to 4 Within the erected carton, as shown in Figs. 9 to 11, and preferably employing an automatic mechanism of an assembling machine which may form a part of, or be associated with, the carton erecting machine, these handle members, already completed, but in flat form as shown in Fig. 3, are arranged in a hopper with their edges hearing the

wing members

27 and 28 as the leading edges for feeding purposes. As each of the handle members is individually fed from the hopper, with a set-up carton body properly indexed below it, plow means arranged in the mechanism at opposite ends of the feed member will plow apart the sets of

wing members

27, 28, being aided in such operation by the reliefs 29 of the wing members 27. With the parts of the handle member thus adjusted to substantially the arrangement shown in Fig. 4, it will be forced into the waiting carton body centrally longitudinally thereof, Fig. 10, with its end edges aligned with the slots 16 of the inner plies of the carton end walls and its

outspread wing members

27, 28 in register with the openings 15 but in position to overlie the ears 17 of these wall plies. Either during or after insertion of the handle member into the carton body in this manner, probes b, Fig 9, will be inserted through the apertures 18-19-20 to exert pressure upon the ears 17 and thus distort or displace them inwardly of the carton (Fig. 9) sufliciently to raise their lower edges to a height which will permit the wing members 27 28 to enter behind them and be thus positioned and retained by the thereafter released ears 17 and between these ears and the overlapped end flaps 4 and capable of sliding vertically between these parts while guided by the slots 16 in the inner plies of the end walls, as indicated in broken lines in Fig. 11. Also, as shown in Fig. 11, the wing members will arrest upward movement of the handle member when their upper edges abut against the top folds of the end walls.

Thus, whether the handle member is in its depressed position or is raised for carrying purposes, it will be held in proper assembled position in the carton by the retention of its

wing members

27, 28 between the inner and outer plies 7 and 9 of the end walls, and this has advantages in that it makes for facility in the introduction into the carton of the containers (beer cans) or the like articles that it is particularly designed to package.

Although the erection of the carton and the assembly of the handle member therewith have herein been described'as primarily the functions of automatic machinery, it will be obvious that, as hereinbefore mentioned, these 7 operationsmay be performed manually.

However, inasmuch as practically all packaging of commodities. is now done. automatically, in line production, the. adaptability. of the. carton of; the invention and its handle: member to. erection and assembly by automatic machinery; such as. might. be embodied: in line production apparatus, is. of major impprtance.

Having further reference to the handle: member of the invention, it will. be seen that by making it of a blank which will providea folded edge longitudinally of both its top and bottom, in order to. give; it double thickness, rather than having a told at one edge only, greater facility in performing the gluing operation is attained and, more over, no spreading of the two thicknesses of the body of the member will occur when the' plow-spreading of the wing members 27', 28 is performed.
