Ellis, Ladue, and James I. Solomon, Kirkwood, Mo., assignors to Anheuser-Busch, Incorporated, St. Louis, Mo., a corporation of Missouri Filed .lune 14, 1961, Ser. No. 117,150 Claims. (Cl. 206--65) The present invention relates to paperboard cartons and more particularly to cartons of the open end type adapted for the retention of two rows of chimed cans, said carton having bottom and top chime engaging tabs.

The present invention is an improvement on the carton shown in United States Patent No. 2,963,148 granted December 6, 1960, which under certain conditions allows the cans therein to become loose and fall out. This is especially true during the carrying of the package, since the top wall bows or flexes upwardly thereby tending to unlock the upper retaining tabs.

One of the principal objects of the present invention is to provide an inexpensive carton for two rows of chimed cans having the advantages of open end cartons with center partitions, including preventing the upper wall from bowing away from the tops of the cans, preventing the upper retaining flaps from becoming disengaged, and providing material between the opposite cans in the two rows both at the top and bottom.

Another important object of the invention is to provide an eliicient, inexpensive form of open end carton for two rows of chimed cans, such carton having substantially all the advantages of open end cartons with center partitions but being constructed with substantially less material.

A further object of the invention is to provide an open end, sleeve type carton for two rows of chimed cans held side-by-side, in which means are provided at top and bottom for holding the cans in accurate side-by-side relation without the tendency for the chimes of cans in one row to overlap or ride onto the chimes in the other row.

A still further object of the invention is to form on both of the panels against which the can ends bear, a central abutment or contacting means which is adapted to engage edgewise on the chimes of the cans and hold them firmly against their adjacent panels thus assuring that the chimes at the opposite ends of the cans in adjacent rows will not ride one upon the other.

Other objects and advantages of the present invention will become apparent as the description proceeds.

In the drawings:

FIG. l is a perspective view of an open end carton embodying the present invention showing the chimed cans positioned therein,

FiG. 2 is a plan View of a blank embodying the present invention, and

FIG. 3 is a cross-sectional view of the carton taken along the line 3-3 of FIG. l showing paperboard means between the chimed cans both at the top and bottom.

The invention, as herein disclosed, is embodied in a one-piece carton formed from a strip of foldable paperboard joined to provide an open rectangular, collapsible sleeve. On one of the walls which contacts the can ends is formed a central, narrow, upstanding abutment or partition portion against which the can chimes may engage laterally. On this abutment or partition a pair of opposed, narrow strips project toward the adjacent can chimes and such strips are sufficiently narrower than the abutment or partition so that they may bear directly edgewise against the edges of the adjacent can chimes.

On the top wall are downwardly extending tabs with rebent portions which provide material between thev the top wall and keep the top wall adjacent tothe top of the cans. This prevents the top wall can retaining tabs from becoming disengaged from the top chimes of the cans and prevents the cans from falling out of the carton.

Referring particularly to the drawings, the carton is indicated as a whole at 5, and comprises an end wall panel 6 which may for convenience `be considered the top wall, two side wall panels 7 and 8, and a second end wall panel, for convenience termed the bottom wall, formed of two

sections

9 and 18. The sections are formed with narrow attached

strips

11 and 12, dened from sections 9 and it? by crease or score lines 13 and 14.

These strips may if desired be secured together as by means of adhesive to complete the bottom wall. The walls are hingedly related along separating crease lines indicated at 15 land 16. The top wall 6 may if desired be creased centrally at 17, thus providing a pre-glued and collapsible construction. With this arrangement, the two sections of the bottom wall will fold upwardly about the hinge provided by the crease lines 13 and 14 and the side walls 7 and 8 will move in to lie flat against the bottom sections 9 and 1t?. At the same time the two halves of the top panel 6 will be folded about the crease line 17, allowing the sections of the top panel to be folded one against the other.

When the carton is brought into can carrying condition, two rows of cans indicated at 18 with chimes -19 thereon may be loaded into the carton by sliding them endwise thereinto. In order to assure accurate positioning of the cans there is provided on the narrow strips 11 and 12 a means for engaging downwardly against the upper surfaces of the can chimes to retain the can ends in close relation to the

carton bottom sections

9 and 10. This means preferably comprises additional

narrow retaining strips

20 and 21 integrally carried by the

respective strips

11 and 12. These retaining strips are defined from

strips

11 and 12 by

crease lines

22 and 23 and in their operative positions the strips are folded to extend downward, in which position the edges of the strips may bear against the adjacent edges of the chimes 19 of the cans.

Due to the action of the retaining strips the cans, when moved into the cartons through the open ends, will slide inward with their ends engaged substantially at against the

bottom panels

9 and 10. rhis will avoid any tendency of the can chimes at the Opposite or upper ends of the cans to lock edgewise against each other which would cause one of the cans to assume a tilted position.

Tabs 25 are preferably formed in the top wall 6 to serve as finger openings whereby the lled carton may be carried. The tabs 25 are pushed downward by the ultimate user of the package. These tabs 25 may have ears 25a thereon to facilitate moving the tabs 25 out of the plane of the top wall 6 and to make the tab 25 morel comfortable.

The cans may be retained within the carton and preresiliency of the foldable paperboard and thefedges ofl the tabs will engage edgewise against the inner portions of the can chimes thus preventing the cans from movement outwardly of the carton.

The improvement to the carton hereinbefore described comprises means connected to the top wall 6 to retain the top wall 6 in close relation to the tops of the cans 18 at all times. The top wall 6 is provided with tabs 28 having a downwardly extending portion 29 and a shorter upwardly rebent portion 30, which is rebent toward the unstruck portion of the top wall 6 as shown.

These tabs 28 are of predetermined width and provide v material between the chimes 19 of opposing cans 13 in the two rows. In addition, the rebent portions 3i) lock under the upper chime of a can 18 to prevent the top wall from exing upwardly when the carton is carried by the carrying means. The resiliently hinged tabs 26 are thereby restricted from becoming disengaged from the cans and maintain their retaining relation with the can chimes 19 during carrying of the carton. With the pre-glued cartons, the tabs 28 should be bent and rebent into the position shown in FIG. 3 before the cans are slid endwise into the carton.

The carton may be provided with scores 31 and stepped scores 32 to provide a small section which can be pushed in and then torn down in order to release the cans from the carton.

From the foregoing it is apparent that the present invention provides an effective open end can carton formed of a relatively small amount of paperboard, whereby it can be inexpensively produced. Due to the center partition strip having the downwardly projecting retaining strips the cans are guided to move accurately into the carton with the chimes of cans in adjacent rows maintained in -side by side relation without likelihood of the chimes at the upper ends riding one upon the other.

It may be noted that while the retaining strips for engagement with the chimes have been described as located on the bottom wall, this has been merely for convenience of description as it is broadly immaterial in practice which of the can end engaging walls is considered the top and which is considered the bottom.

It is preferable not to have the cartons pre-glued along the

narrow strips

11 and 12 although they may be if so desired. If the cartons are not pre-glued, then a crease along the longitudinal center 17 of the top wall 6 will not be necessary. It is preferable to deliver the carton to the packer in the form of flat unglued blanks which are wrapped around a group of two rows of cans.

In this form of the invention, a convenient procedure for enclosing the cans with the carton blank is to place two rows of cans upon the top panel 6 whose tabs 28 have been bent at right angles out of the plane of the top wall 6 with their rebent portions 3d engaging the chimes :of the cans; then fold upwardly the side walls 7 and 8; and then fold the

strips

11 and 12 and the attached

retaining strips

20 and 21 one against the other and move them to a generally right angular position with respect to their attached

bottom wall sections

9 and 10. Adhesive is applied to one of the

strips

11 or 12.

The bottom wall sections 9 and 1d are folded over against Vthe cans 18 and at the same time the folded

strips

11, 12, 2t! and 21 are brought into place between the can rows, thus bringing the carton parts into the relationship shown in FIGS. l and 3. The

strips

11 and 12 are held together until the adhesive has set. This may be done by applying pressure laterally against the side walls 7 and 8. The strips 21B and 21 by bearing downward on the edges of the lower chimes 19 hold the cans in place against the bottom wall panels 9' and 10 and tend to prevent locking of the chimes one over the other. The tabs 2S with their depending portions 29 and rebent portions 30 tend to prevent the locking of the upper chimes one over the other, and at the same time, lock the top wall 6 to the cans so that the top wall 6 does not flex upwardly during carrying, thereby eliminating the possibility that the upper retaining tabs 26 will accidentally become disengaged from the can, as might happen if the tabs 28 are not present. Y

This invention is intended to cover all changes and -moditications of the example of the invention herein chosen for purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention.
