6 Claims. (Cl. 206-65) Matter enclosed in heavy brackets appears in the original patent but forms no part of this reissue specification; matter printed in italics indicates the additions made by reissue.

The present invention relates to paperboard cartons andmore particularly to cartons of the open end type adapted for the retention of two rows of chimed cans.

An important object of the invention is to provide an efiicient, 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 for. holding the cans in accurate side-by-side relation wthout the tendency for the chimes of cans in one row to overlap or ride into the chimes in the other row.

A still further object of the invention is to form on one 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 themfirmly 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. 1 is a perspective view of an open end can carton constructed in accordance with the present invention, showing chimed cans in place therein;

FIG. 2 is a perspective view showing the carton in substantially collapsed position;

FIG. 3 is a fragmentary, cross-sectional detail view showing the means for engaging edgewise against the can chimes to retain the can ends flat against their adjacent wall panels;

FIG. 4 is a plan view of a preferred form of blank from which the carton of the present invention may be formed; and

FIGS. 5 and 6 illustrate a perspective view and plan view respectively of a carton and carton blank, similar to FIGS. 1 and 4, except that the carton is intended to be formed around the cans.

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.

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 10. The sections are formed with narrow attached strips, 11 and 12, defined from sections 9 and 10 by crease or score lines 13 and 14. These strips are secured together as by means of adhesive to complete the bottom wall. hingedly related along separating crease lines indicated at 15, 15 and 16, 16 and the top wall 15 is creased centrally at 17, thus providing a collapsible construction, as illustrated in FIG. 2. According to this construction 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 fiat against the bottom sections 9 and 10. 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 to fully expanded condition two rows of cans indicated at 18, 18 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, as shown in FIGS. 1 and 3, 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 flat against the bottom panels 9 and 10. This 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.

Die cut holes 25, 25 are preferably formed in the top wall 6 to serve as finger openings whereby the filled carton may be carried.

The cans may be retained within the carton and prevented from endwise movement by means of inwardly foldable tabs 26, 26 and 27, 27 formed respectively in the upper and lower walls of the carton. These tabs when folded inwardly tend to move against the can ends due to the resiliency of the foldable paperboard and the edges of the tabs will engage edgewise against the inner portions of the can chimes thus preventing the cans from movement outwardly of the carton. there is no connection between the median portion of the top wall and the bottom wall, the top wall will tend to flex upwardly when the carton is carried by the carrying means. The resiliently hinged tabs, however, will swing downwardly away from the normal plane of the top wall and thus tend to remain in retaining relation with the can chimes.

From the foregoing it is apparent that the present in vention 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 main tained 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 merelyflfor convenience of description as it is broadly immaterial Reissued Jan. 9,1962

The walls are Since [1 practice which of the can end engaging walls is conidered the top and which is considered the bottom.

In the modified form of the invention shown in FIGS. and 6, the construction is substantially the same as in he first described form except that the carton is delivered the packer in the form of flat unglued blanks which lIB wrapped around a group of two rows of cans. The op panel of the carton also is preferably not formed vith a central crease line.

As shown in FIGS. 5 and'6, the top panel 30 is integrally oined to the two side panels 31, 31, which in turn are ntegrally joined to bottom panels 32, 3 2. On the outer :dges of these latter panels are attaching strips 33, 33 vhich project upwardly between the can rows. The trips 33, 33 carry retaining strips 34', 3-4 which engage lownwardly against the lower can chimes. Crease lines 5, 36, 37 and 38 are impressed transversely of the blank 0 separate the adjacent walls and strips from each other md permit relative folding therebetween.

In this form of the invention a convenient procedure or enclosing cans with the carton blank is to place two ows of cans upon the top panel; then fold upwardly the ide walls; then told the strip 33 and the attached reainin g strip 34 one against the other and move them to L generally right angular position with respect to their tttached bottom wall sections 32, 32. Adhesive is aplied to one of the strips 33.

The botto-m'wall sections are folded over against the :ans and at the same time the folded strips are brought nto place between the can rows, thus bringing the caron parts into the relationship shown in FIG. 5. The trips 33, 33 are held together until the adhesive has set. Fhis may be done by applying pressure laterally against he side walls 31, 31. The package of two rows of cans hus formed is then substantially the same as the packlge shown in FIG. 1. The strips 34, 34 by bearing downvard upon the edges of the can chimes, hold the cans in lace against the bottom wall panels 32 and tend to pre- 'ent locking of the chimes one over the other at the x-ther ends of the cans.

While the present description sets forth a preferred :mbodiment of the invention, various changes may be made in the construction without departing from the pirit of the invention, and it is therefore desired that the rresent embodiment be considered in all respects as llustrative and not restrictive, reference being had to the lppend'ed claims rather than to the foregoing description 0 indicate the scope of the invention.

I claim:
