Ila WEE Hf. F G/W751? 7 Ma #8 ATTOAIVLKS United States Patent 3,006,530 PAPERBOARD CARRIER HAVING MEANS FOR SEPARATING CANS THEREIN Homer W. Forrer, Atlanta, Ga., assignor, by mesne assignments, to The Mead Corporation, Dayton, Ohio, a

corporation of Ohio Filed Oct. 31, 1958, Ser. No. 771,033 Claims. (Cl. 229-40) This invention relates to paperboard carriers for cans and more particularly to a wrapper type paperboard carrier arranged to maintain a can load therein evenly positioned for stable vertical stacking. This is a continuationin-part of copending application Serial No. 626,385, filed December 5, 1956, now abandoned in favor of the present application.

In securing a paperboard wrapper carrier about cans arranged in more than one row, there is a natural tendency for the lateral rim portions or chines of the cans in one row to ride or slip upwardly on the rim portions or chines of the adjacent row of cans and thereby present uneven or slanting top and bottom surfaces on each wrapper packaged group of cans that often makes it quite difiicult to stack such package units in a stable manner for retail display or the like.

It has previously been proposed to dispose partition means within a carrier structure of this sort between the rows of cans so as to provide a separating element at the can chines by which they are prevented from shifting to ride upon one another and throwing the package unit out of square. The use of such partition means in wrapper type carriers, however, involves difiiculties, particularly where such carriers are secured by bottom wall locking tabs rather than being glued.

Bottom wall locking tabs are normally centered for securing manipulation at the dead spaces within a package unit of cans resulting from the cylindrical form of the cans, but when a chine separating partition means is employed in the carrier it becomes necessary to shift the locking tabs off center to avoid this partition. There is enough dead space between the cans to permit this oif center shifting of the locking tabs intermediately of the can rows, but it is not possible to provide locking tabs at the ends of the can rows if this is done, as the space available for end locking tabs is originally quite limited and becomes entirely inadequate if obstructed by partition means. In the absence of end locking tabs, the bottom wall lap panels are left insecure adjacent their ends so as to be subject to being caught and torn loose during handling unless arranged specially to avoid this result, or unless the partition means is provided in a form that allows end locking tabs to be provided as well.

According to the present invention chine separating partition means is provided in a paperboard, wrapper type, carrier for cans so as to obtain effective chine separation at both the top and bottom of the carrier, while at the same time making it possible to form a secure and serviceable carrier with or without end locking tabs as desired.

The present invention is described in further detail below in connection with the accompanying drawings, in which:

FIG. 11 is a sectional detail in plan taken substantially along the line 8-8 in FIG. 7.

Referring now in detail to the drawings, a stack of three paperboard wrapper carriers embodying the present invention is shown illustrated in FIG. 1, each of the carriers being indicated generally by the numeral 10 and having two rows of cans C arranged therein.

The cans C each have top and bottom rims or

chines

12 and 14, respectively, that extend through aligned elongated positioning slots arranged along top and bottom hinge lines of the carrier with a top and bottom slot adjacent each can C. A partition section 15 is arranged between the top lateral rims 12 of the two rows of cans C within the carrier 10, while a separating flange or flap 26' is disposed between the bottom rims 14 to prevent the top and

bottom rims

12 and 14 from riding on one another and thereby maintaining the packages square so that additional paperboard wrapper carriers loaded with cans C can be stacked on top of one another in a stable manner.

The above noted positioning slots in the carriers 10 have tabs 16 extending thereat, as illustrated further in FIGS. 2 and 3, and the length of each slot is less than the diameter of the cans C so that the top and

bottom rims

12 and 14 extend through the slots to be retained in secured relation therein. The paperboard wrapper carrier 10 otherwise comprises a top wall panel 18, side wall panels 20, 2'2 foldably hinged to opposite side edges of top wall panel 18, and a pair of bottom

wall lap panels

24, 26 foldably hinged at the respective bottom edges of

side wall panels

20, 22 and proportioned to overlap across the bottom ends of the cans C, with the terminal flap portion 26' foldably hinged on the inner bottom wall lap panel 26 for disposition in separating relation between the bottom can ends. The wrapper thereby forms a rectangular four sided package having open ends of the type disclosed in US. Patent No. 2,786,572, issued March 26, 1957. The invention is not limited to lap panels arranged on the bottom side of cans C, however, as the lap panels can be arranged on any side of the carrier 10.

Top wall panel 18,

side wall panels

20, 22 and bottom

wall lap panels

24, 26 comprise a blank (see FIG. 4) having transverse score lines therein to arrange the panels in a foldably hinged series, with each panel having a length corresponding to the multiple diameter of a row of cans C. The width of the

side wall panels

20, 22 corresponds to the height of the cans C arranged within the carrier and the bottom

wall lap panels

24, 26 when overlapped and secured-form a composite bottom wall having a width equal to that of the top wall panel 18 and corresponding to the width of the two rows of cans C.

The paperboard wrapper carrier 10 is arranged to be tightly folded and secured about two rows of cans C during a packaging operation, the bottom

wall lap panels

24, 26 being formed with aligned locking and retaining

tabs

28 and 30, respectively, for securing the end portions of the wrapper together by manipulation of the locking tabs 28 so as to extend them from the outer bottom wall lap panel 24 in which they are formed to an interlocking position inwardly through the openings in the other bottom 'wall lap panel 26 at the retaining tabs 30 therein, as disclosed and claimed in the above noted US. Patent No. 2,786,572.

To allow the wrapper to be drawn about the cans C tightly, depressible tabs 32 are arranged in each of the bottom

wall lap panels

24, 26 whereby the end portions of the wrapper can be gripped through the openings formed -by depressible tabs 32 and pulled tightly about the cans C so that the locking tabs; 28 can be extended in securing position, as disclosed and claimed in US. Patent No. 2,809,486, issued October 15, 1957.

An outer strip 34 is provided on the edges of the top wall panel 18,

side wall panels

20, 22 and bottom wall lap panels'24, 26, the outer strip 34 being arranged on the edges thereof perpendicular to the transverse score lines between adjacent panels, and extending throughout the width of top wall panel 18 and

side wall panels

20, 22, and for a portion of the width of bottom

wall lap panels

24, 26, in the manner and for the purpose disclosed and claimed in copending application Serial No. 602,114, filed June 25, 1956.

A lateral extension 38 is formed on one of the strips 34 adjacent the top wall panel 18, the lateral extension being intermediately foldable to define the partition section 15 and a securing section 42. The securing section 42 has a projecting tab member 44 extending from its outer edge with the length of tab member 44 being substantially one-half that of the width of securing section 42. During the folding development of the blank, as shown in FIG. 5, the .tab member 44 is disposed between the other outer strip 34 and the adjacent top wall panel 18 on the edge of carrier opposite the edge at which lateral extension 38 is formed thereby securing the lateral extension 38 to the top wall panel 18. Glue is applied to the face of outer strips 34 and securing section 42, as indicated by stippling in FIG. 4, whereby upon folding of outer strips 34 and securing section 42, the outer strips 34 will be secured in face-to-face relation with the adjacent panels by the glue application.

Top wall panel 18 is provided vw'th apertures 46 arranged intermediate the width of top wall panel 18 for gripping carrier 10 in carrying relation. Aligned apertures 48 are provided in lateral extension 38 and extend through partition section and securing section 42. When lateral extension 38 is folded in face-to-face relation with top wall panel 18, as shown in FIG. 5, the lateral extension apertures 48 coincide with the top wall panel apertures 46 and the score line between securing section 42 and partition section 15 is arranged cent-rally of the top wall panel apertures 46.

Upon further folding of partition section -15 in perpendicular relation to securing section 42 along the score I line between the

respective sections

15, 42, the partition section 15 is disposed centrally of top wall panel apertures 46, as s'hown'in FIG. 3. The distance between the top wall panel apertures'46 is greater than the distance between the apertures 48 formed in partition section 15 since apertures 48 are elongated in partition section 15. Thus, a portion of the top Wall panel 18 is accessible between apertures 46 for finger gripping in a carrying relation. The modified embodiment of the paperboard wrapper carrier of the present invention illustrated in. FIGS. 6, 7 and 8, and indicated generally therein by the reference numeral 100, like the previously described embodiment, comprises a top wall panel 101, a pair of

side wall panels

102 and 103 at opposite sides of the top wall panel 101, and a pair of bottom

wall lap panels

104 and 105 respectively associated with the

side wall panels

102 and 103; and all of which panels are arranged as a foldably hinged series in a blank of elongated form as seen in FIG. 6.

When folded and secured about a package group of cans C, such as is indicated by dotted lines in FIGS. 6, 7

and 8, the paperboard wrapper assumes the form illustrated in FIG. 7, in which the top wall panel 101 is shown arranged across the top of the packaged rows of cans C, with the

side wall panels

102 and 103 folded downwardly at the sides thereof and the bottom

wall lap panels

104 and 105 overlapped therebeneath. As in the previously described embodiment, upper and

lower positioning slots

106 and 107 are spaced along the foldably hinged edges of the

side wall panels

102 and 103 for retaining engage ment thereat with the chines of cans C, and upper and lower medial chine separating means are provided at 108 and 109.

The upper chine separating means 108 comprises a pair of tabs formed in the top wall panel 101 along medial hinge lines at 110 and 111, as seen in FIG. 6, for folding downwardly in separating relation between the upper chines of the cans C at the ends of the rows forming the package group, as seen in FIG. 7 In a package group of the size illustrated, in which there are two rows of these cans 0, top chine separation of the end pairs of cans C is adaquate for maintaining the package square thereat. Additional tabs 108 can be readily provided whenever needed or desired, as fully sufiicient space otherwise remains in the top wall panel 101 for locating depressible tabs 112 at the dead spaces between the cans C of the package group to provide finger apertures for carrying purposes.

It should also be noted that the tabs 1087are specially arranged in the top wall panel 101 in that the hinged extent thereof is arranged oppositely from the respective medial hinge lines 110 and 111. This arrangement provides a significant advantage in manipulating the tabs 108 to a chine separating disposition during an automatic packaging operation as is disclosed and claimed in copending application Serial No. 795,086, filed February 24, 1959, now Patent No. 2,933,867, granted April 26, 1960.

The lower chine separating means 109 comprises a flange formed by a flap member foldably hinged at the overlapped edge of the inner bottom lap panel 104 along a score line 113. This flap member forming the lower chine separating means 109 is also specially formed in that it is located and restricted in length along the score line 113 so as not to extend at the open ends of the wrapper earlier substantially beyond the point at which the bottom edge chines of the respective end pairs of packaged cans C are adjacent. In addition, both the inner and outer bottom lap panels 104 and have the end edges thereof relieved diagonally toward the overlapping edges thereof as illustrated at 114 and 115, respectively, so as to maintain substantially the entire extent of these end edges within the cylindrical outline of the end pairs of cans C, as seen best in FIG. 8.

By this arrangement, in which respect it should be 'noted that the first described embodiment is substantially similar, it is possible to maintain the

bottom lap panels

104 and 105 tight and secure against beingtorn loose during handling in instances where locking and retaining

tabs

116 and 117 are only provided intermediately of the rows of cans C. The wrapper carrier 100 further incorporates lap

panel tightening apertures

118 and 119 in the same manner and forthe same purpose as in the first described embodiment.

The additional embodiment of the paperboard wrapper carrier of the present invention illustrated in FIGS. 9, 10 and ll, and indicated generally by the reference numeral 200 therein, incorporates a top wall panel 201 and a pair of

side wall panels

202 and 203 that are counterparts of those in wrapper carrier embodiment 100 just described; the top wall panel 201 having upper chine separating tabs 204 oppositely hinged from

medial hinge lines

205 and 206 therein as well as depressible finger aperture tabs 207; and the

side wall panels

202 and 203 having upper and lower can chine positioning

slots

208 and 209 spaced along the foldably hinged edges thereof.

7 In the presently described wrapper carrier 200, however,

bottom lap panels

210 and 211 are provided that incorporate end locking and retaining tabs 212 and 213', as well as intermediate locking and retaining

tabs

212 and 213, along with a lower chine separating flange 214. The chine separating flange 21-14 is again formed by a flap member that is foldably hinged at the overlapped edge of the inner bottom lap panel 210 along a score line 215 thereat, and that is located and restricted in length so as not to extend at the open ends of the wrapper carrier 200 substantially beyond the point at which the bottom edge chines of the respective end pairs of packaged cans C are adjacent. The remaining lengthwise extent of the inner bottom lap panel 210 at each end of the separating flange or flap member 214 is formed with transversely extending portions 216 having a suflicient reach to overlie the end locking tabs 212 in the outer bottom lap panel 211 so as to allow location of the end retaining tabs 21 3 in registration therewith for interlocking manipulation medially of the erected wrapper carrier 200. The

bottom lap panels

210 and 211 are also formed with tightening apertures at 217 and 218 as in both of the previously described embodiments.

The present invention has been described in detail above for purposes of illustration only and is not intended to be limited by this description or otherwise except as defined in the appended claims.
