4 Claims. (Cl. 206-65) The present invention relates to paperboard cartons and more particularly to cartons of the open end type adapted vfor the retention of two rows of chimed cans.

An important object of the invention is to provide au l efficient, 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 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 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 them rmly 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 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 sutliciently narrower than the abutment or partition so that they may bear directly edgewise against the edges of the adjacent can chimes.

Referring praticularly 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. The walls are hingedly related along separating crease lines -indicated at 15, 1S 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 into lie flat 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 lassure 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 dened 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 1.9 ofthe cans.

Due to the action of the retaining stl-ips 'the cans, when moved into the cartons through the open ends, will slide inward with their ends engaged substantially tiat 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 Ato assume a tilted position.

Die cut holes 25, 25 are preferably 'formed in vthe `top wall 6 to serve as linger 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 vthe carton. Since there is no connection between the median portion of the top wall and the bottom wall, the top wall will tend'to ex 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 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 Vthe other.

It may be noted that while the retaining strips 'for engagement with the chimes have been described las 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.

In the modied form of the invention shown in FigsA 5 and 6, the construction is substantially the same as in the first described form except that the carton is delivered to the packer in the form of at unglued blanks which are wrapped around a group of two rows of cans. The top panel of the carton also is preferably not formed with a central crease line.

As shown in Figs. 5 and 6, the top panel 30 is integrally joined to the two side panels 31, 31, which in turn are integrally joined to bottom panels 32, 32. On the outer edges of these latter panels are attaching strips 33, 33 which project upwardly between the can rows. The strips 33, 33 carry retaining strips 34, 34 which engage downwardly against the lower can chimes. Crease lines 35, 36, 37 and 38 are impressed transversely of the blank to separate the adjacent walls and strips from each other and permit relative folding therebetween.

In this form of the invention a convenient procedure for enclosing cans with the carton blank is to place two rows of cans upon the top panel; then fold upwardly the side walls; then fold the strip 33 and the attached retaining strip 34 one against the other and move them to a generally right angular position with respect to their attached bottom wall sections 32, 32. Adhesive is applied to one of the strips 33.

The bottom wall sections are folded over against the cans and at the same time the folded strips are brought into place between the can rows, thus bringing the carton parts into the relationship shown in Fig. 5. The strips 33, 33 are held together until the adhesive has set. This may be done by applying pressure laterally against the side walls 31, 31. The package of two rows of cans thus formed is then substantially the same as the package shown in Fig. 1. The strips 34, 34 by bearing downward upon the edges of the can chimes, hold the cans in place against the bottom wall panels 32 and tend to prevent locking of the chimes one over the other at the other ends of the cans.

While the present description sets forth a preferred embodiment of the invention, various changes may be made in the construction without departing from the spirit of the invention, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

I claim:

l. An open end, rectangular, sleeve-type carton formed of exible, folding paperboard and adapted to enclose two rows of closed, chimed cans in side-by-sde relation, said carton having a top wall panel, side wall panels joined to opposite edges of the top wall, a bottom wall panel section connected to the lower end of each side wall, the free edges of the bottom wall panels meeting centrally of the bottom, each of such panel free edges having connected thereto an upwardly projected strip, the upper edge of each of the strips carrying an integral, downwardly and outwardly folded strip having a width less than the upwardly projecting strip, whereby the lower edge of each downwardly projecting strip provides a downwardly presented abutment spaced from the adjacent bottom panel, the upwardly and downwardly projecting strips being of such length as to extend substantially the distance between the carton open ends, means located centrally of the top wall and aligned with the axis through the open ends of the carton for carrying the carton, there being no supporting connection between the median portion of the top wall and the bottom, whereby the top wall is subjected to exing when the carton is suspended by the carrying means, inwardly foldable, chime-engaging tabs formed within the contour of the top wall and adapted to be folded through 180 to their chime-engaging position, such tabs being adapted, due to the resilience of the paperboard, to swing inwardly away from the normal plane of the top wall and remain in chime-engaging condition as the median portion of the top Wall exes upwardly when the carton is carried by the carrying means.

2. A package comprising a group of two juxtaposed, parallel rows of closed, chimed cans held upright within a rectangular, open-end carton formed of exible, folding paperboard, such carton including a top Wall panel enclosing the upper end of the can group, side walls enclosing the sides of the can group, each side wall carrying at its lower end a bottom wall section enclosing the bottoms of one row of cans, the free edges of the bottom sections meeting centrally along the line between the can rows and each edge having connected thereto an upwardly projecting strip disposed between the can rows, such strips being secured tlatwise against each other and each strip carrying an integral, downwardly projecting strip of less width than the upwardly projecting strips, such downwardly projecting strips being folded on the outer sides of their attached strips and in contacting relation with the can sides, such strips extending the length of the carton between its open ends with the bottom edge portions of each of the downwardly folded strips pref sented respectively in abutting relation to the upper surfaces of the can chimes on the lower ends of the cans of the two can rows to hold the cans against their bottom wall sections.

3. A package as defined in claim 2, including means located centrally ofthe top panel inline with the meeting surfaces of the can rows for carrying the package, there being no supporting connection between the median portion of the top wall panel and the bottom, whereby the top wall panel is subjected to tiexing upward partially away from the tops of the cans when the package is suspended by the carrying means, inwardly foldable chimeengaging tabs formed within the contour of the top wall panel adjacent the end cans in the rows, such tabs being folded through -to their chime-engaging position and being urged, due to the resilience of the paperboard, to swing inwardly away from the normal plane of the top wall panel, whereby such tabs tend to remain in engagement with the can chimes as the median portion of the top wall is flexed upward when lthe package is carried -by the carrying means.

4. An open end, rectangular, sleeve-type carton formed of exible, folding paperboard and adapted to enclose two rows of closed, chimed cans in side-by-side relation, said carton having a top wall panel, side wall panels joined to opposite edges of the top wall panel, a bottom wall panel Section connected to the lower end of each side wall panel, the free edges of the bottom wall panels meeting centrally of the carton, each of such panel free edges having connected thereto an upwardly projected strip, the upper edge of each of the strips carrying an integral, downwardly and outwardly folded strip having a width less than the upwardly projecting strip, whereby the lower edge of each downwardly projecting strip pro vides a downwardly presented abutment spaced from the adjacent bottom panel for engagement with chimes presen-ted by said cans to prevent vertical movement of the cans relative to the bottom wall panel sections of the carton, the upwardly and downwardly projecting strips being of such length as to extend substantially the distance between the carton open ends, and means integral with the carton engageable with the cans for preventing them from accidentally moving longitudinally of the carton out of an end of the carton.
