WRAP-AROUND CARRIER WITH ARTICLE RETAINER
F~P~a oz zne mvenm on This invention relates to article carriers and, more particularly, to article carriers having at least partially open ends.
Aa~ c~nmnd of the Invention Wrap-around article carriers are commonly designed to have ends which are either partially or entirely open. In , either case the carriers must be provided with means for preventing the articles from falling out the ends. Beverage cans, for example, are held in place partly by the tension , IO applied by the carrier blank being wrapped very tightly about them and by the engagement of the top and bottom flanges of the cans with the edges of cutouts in the side panels of the carrier through which the flanges of the cans extend. This design is .
facilitated by the fact that cans have substantially flat tops and bottoms of the same diameter as the body of the can, which allows the carrier blank to be tightly wrapped around the cans.
Problems arise when the articles are not of ,uniform dimensions, and. particularly when the articles are tapered at the bottom so as to cause the bottom portions of.the articles to be spaced apart. Wrap-around carriers for: use with tapered tubs of the type used as pudding. or margarine containers are especially troublesome because of the -difficulty in wrapping.
them .tight,ly enough to" prevent movement of the tubs :when the package is lifted and carried. Movement of:the.containers is a problem even when~the.carrier.includes side slots through which flanges,on. ,the tops of ~ the vtubs protrude,' since' such wan arrangement . ;does not , hold :.the bottom. _~p,ortions of the ' tubs tightly. in place : : ... . .. .. . _ . ~ _ ..

and would not be able to prevent movement of the bottom portions of the container toward and away from each other. Moreover, the bottom of the carton is not stable under such conditions. What is needed is an article spacing or retention means which effectively prevents the spaced bottom portions of articles from moving with respect to each other, and also prevents the bottom portions of end articles in a carrier from moving toward the open end of the carrier.
grsPf Summary of the Invention In accordance with the invention, a wrap-around carrier having a top panel and side panels is provided with a bottom panel comprised of overlapping inner and outer bottom panel flaps. The inner bottom panel flap contains an opening.near an end of the carrier, and the outer bottom panel flap includes an integral article retaining flap which is hingedly connected to the outer bottom panel flap adjacent an inner edge portion of the opening. In forming the carrier, the retaining flap is pivoted up through the opening into the interior of the carrier, .
where it engages the bottom portions of adjacent end articles of adjacent rows of articles and prevents outward movement of the articles as well as relative movement of the articles toward and away from each other.
In a preferred form of the invention the retaining flap fold line is~substantially parallel to the. end of~the carrier.
In addition, the retaining .flap includes spaced fold lines extending-transversely of the -retaining flap fold line.
Preferably, the transverse fold line s converge toward each other, producing a tapered retaining flap capable of conforming to th'e sloped bottom portions of the articles.- w~
The resulting°retaining flap-is three dimensional, 'having a central:vsection directed'toward the interior of the carrier and side.faces-.or'sections extending-betweenvadjacent end articles. Preferably, the opening through which the retainer flap_.:extendsw_is narrower than' the normal ' distance .between the side:faces;=thereby exerting a biasing-force on the / side - faces to - cause the : flap = to~ stand upright ~in the 'rpacJcage .
Because the retaining flap fits~snugly between the~spaced bottom , W092/09498 -3- r~ PCT/US91/08452 ~~~? ~:~~'.~8 (_", , . .
portions of the end articles, the articles are held in place against outward movement.
In addition to the retaining flap holding the bottom portions of the end articles in place, it also functions to interconnect the inner and outer bottom panel flaps, thus providing reinforcement 'to any other locking means connecting the bottom panel flaps.
The above and other aspects of the invention, as well as other benefits, will readily be apparent from the more detailed description of the preferred embodiment which follows.

Dera Wed Description of the Preferred Embodiment Referring to FIG. 1, a wrap-around carrier 10 comprises a top panel 12 connected along fold lines 14 to side panels 16 which generally follow the contour of the articles T in the carrier. For purpose of illustrating the invention, the articles T are shown as comprising tubs of the type used to contain pudding or margarine or the like. It can be seen that the side panels are inwardly curved at the bottom portion of the carrier as a result of being tightly wrapped around the sloped side portions of the tubs. The side panels adjacent the top panel are provided with slots 18 through which the top flanges F
of the tubs T extend. The top panel 12 is also provided with .
short extensions 20 which cover the flanges of the tubs.
A bottom panel 22 is formed by overlapped inner and outer bottom panel flaps 24 and 26. The inner bottom panel flap 29 is connected to one of the side panels 16 along fold line 28 while the outer bottom panel flap..26 is connected to the other side panel 1,6 along fold .line _30. .:'Extending up from the bottom panel .22 adjacent . the. end articles T. :in the adjacent rows'- of articles in the carrier is a retainer flap 32, which is shown in greater detail in FIG. 2. It can be seen that the retainer flap fits snugly between the angled bottom portions. of the articles T, preventing the bottomwportions from 'moving :-in -~a= direction away from the side panels 16. w -. L_; As shown -in . FIG. ; 3, wherein.: like :reference numerals to those used in FIG. i denote like elemen~s, a blank for forming the carrier 10 comprises~a substantially;rectangular sheet,34 of paperboard _or .-;other :suitable ' material; with- '-the"~~top panel section. 12, being in the .center. of~the.aheet :.and. the. other panel .
sections described above being successively connected.along-the fold lines referred;to above. . Thus thevfold.lines:l9~connecting the top 'panel 12 to the side panels 16 are separated"from each .

other by portions defined by the elongated slits 36 and the short connecting slits 38 which correspond to the extension of the top panel overlying the tub flanges in a carrier formed from the blank. The slots 18 of FIG. 1 through which the tub flanges protrude are formed when the side panels are folded down from the top panel, and the width of the slot corresponds to the length of the short slit 38.
In order to form a carrier from the blank 39, the blank is wrapped around the tubs or other articles to be packaged with the inner and outer bottom panel flaps 24 and 26 in overlapping relationship. The bottom panel flaps 24 and 26 are shown in FIG. 4 as they would appear after being folded in from side panels 16 about the fold lines 28 and 30 just prior to being moved into overlapping relationship. Referring to both FIGS. 3 and 4, the retaining flaps 32 are connected to the outer bottom panel flap 26 along fold lines 40 which are located between the end edges 42 of the flap 26 and the midpoint of the flap. The fold lines 40 are shown as being substantially straight and , parallel to the end edges 42, although they-may be slightly curved or angled as discussed in greater detail hereinafter. A
slit 44 which is also substantially parallel to the end edges 42 of the outer bottom panel flap 26 and which is located between the fold lines 90 and the_end edges 42, forms the opposite edge of the. retainer flap 32.. The sides of the:.retainer flap are defined by slits 46_which extend from the ends of-slit 44 transversely of the end edges 42.toward the interior of the carrier, and by angled slits-48 connecting.the slits 46 and the ends of the fold lines 40. The. retainer flap 32 further includes two- fold -lines 50 ..which extend from the ends of the fold.line 90.and converge.to.the slit 44;.:intersecting the slit ~-44.~. at spaced; ~ points . :' . It.;.._ can be . seen w .that the resulting retaining flap ..;is.;,made... up of 'a central- : face or -: section =-'~52 bounded by, the. fold .lines.,-40 and 50 : and . the slit 44, and of ~ two side ,facesl..or..sections-;.54_ bounded by the s?,-its 44; 46- and 48 and ~_ : .. , _ . . , , the fold lines 50.. . :~' , ._: .. ._,.. __.__ _.._. ..::~,-~ ...
.,..The inner_.bottompanel , flap x24 includes :two modified ~T-shaped .openings or slots 56_.located -so :as.. o be aligned with the retainer flaps 32 when the inner and outer bottom panel flaps WO 92/09498 :i r-~:
are overlapped to form the bottom panel of the carrier. Each cutout or slot 56 comprises a relatively wide elongated slot , portion 58 extending from a transverse slot portion 60.. The slot portion 58 is spaced from and extends transversely of the nearest panel end edge 62, while the slot portion 60 extends outwardly of the slot portion 58 at the end thereof farthest from the panel end edge 62. The slot portion 60 extends generally parallel to the end edge 62. The slot portion 58 is defined by an edge 64 which is spaced from and parallel to the panel end edge 62 and by edges 66 which converge toward the interior of the carrier. The slot portion 60 is defined by an ' edge 68 which~is also parallel to the panel end edge 62 and by edges 70 which connect the edge 68~to the slots 66 at their closest spacing. The angular portion of the inner bottom panel flap 24 adjacent the intersection of edges 66 and 70 comprises opposing tabs 72.
Still referring to FIGS. 3 and 4, the bottom panel flaps are designed to be mechanically connected in a manner generally known.in the prior art. The outer bottom panel flap 26 is connected to an end margin flap 79 along fold line 76. The fold line 76 is interrupted in the central portion by a slit defining a male locking tab 78 and on either side of the tab 78 by the , slits 46 which.coincide.with the fold-line 76. The margin flap 74 also.contains a centrally located~locking opening~~80 the interior edge-_82 .of which extends a substantial distance beyond the. side .edges of :the .opening.
The inne r:bottom panel'flap 24-'contains a centrally located_male locking tab 89.'~defined by end slit 86, side slits 88, ~ angled slits r90 whichrforin ~a neck portions,' ~andr foldline '92 .
; ..The _ locking :, tab .84 . is part of a la=ger"tab' or flap 94 vwhich is connected to the . inner =bottom ~ flap 30 -along ~~fold.,-hine 96 'and _ which.~,further is ~defined:by slits 98 extending from the ends'-of the fold line 96 to=the:slits 90 ofvthevlocking tab 84. ~' ,;~ To ; lock -.the ~. bottom panel ~~ flaps = together; ''wthey-'~are positioned in overlying relationship, with the end~wmargin flap _v-74 .of. the outer'_bottom panel-flap ~aind'the"tab'~99 of 'the inner ...bottom panel .flap being ~-folded%back=a's =illustrated'~in FIGS:' S
and 6. As shown, a smallportion of one end ~of the slot 60 is -xr..;.~
.-.
visible below the folded-back margin 79. The outer bottom flap 26 is then moved to align the locking tab 78 of the margin 74 with the locking edge 86 of the inner bottom flap 24. By folding the margin flap 74 back to its original position the locking tab 78 engages the locking edge 86 and the underside of the inner bottom panel flap 24 to mechanically hold the bottom panel flaps together as the primary lock of the bottom panel.
Th tab 94 is then folded back to its original position and the locking tab 89 is folded about its fold line 92 into the locking opening 80 through the slit 82 to effect a secondary lock. This arrangement is illustrated in FIGS. 7 and 8.
It can be seen in FIG. 7 that when the bottom panel flaps are locked together, the retaining flaps 32 are positioned directly over the openings or slots 56. .Note that the openings _ '15 56 are shown in dotted lines in FIG. 7 while the retainer. flaps 32 are shown in solid lines, 'depicting the slits, and in dot-dash lines, depicting the fold lines of the retaining flaps.
Pressure exerted on the central body sections 52 of the retainer flaps by an externally located movable punch or rod element, not shown but which will be understood by those skilled in the art preferably to be an operating element in an automatic packaging machine, will cause the retainer flaps to be pivoted up about their fold.lines 40 and pushed up into the interior of the carrier through the openings 56 in the inner bottom.panel flap 29. A typical intermediate position of the retaining flap as it would.appear, during this movement.is illustrated in FIG. 9, ' which shows - the. bottom of .ahe . retaining flap, and in .FIG : 10, ,which. shows.,,the. upper.portion.of the retaining .flap as it ' - emerge.s,_-into the interior. of:~the carrier.v.: It: will-.be seen that movement,.of~the-.retainer~flaps through.the~wslots in this manner .causes.the~.side retainer:; sections 59. to <fold,about:their fold ' .lines 50=:as -a :result ~of:;their contact with . he.-edges -~of =the . elongated,; slot portions .58 .- In .particular,': it~ swill . be seen '-that .

~S~'~ k.r;;~f,~
to the combination of stiffness and flexibility o~ the paperboard material. The tabs thus exert a biasing force against the side sections.
Continued pivoting movement of the retaining flaps about the fold lines 90 will continue to fold the side sections 54 of the retaining flap until the retaining flap reaches its fully extended position in the interior of the carrier. This position, as illustrated in FIGS. 2 and 11, can be seen to be substantially vertical. The continued urging of the tabs 72 .
against the side sections 54 helps to maintain the retaining flaps in their fully elevated position. As best shown in FIG.
11, the side sections 54 are located so as to contact the sides of the tubs or other articles T so that the tubs are securely held between the side panels of the carrier and the retaining flap. The articles are thus divided and separated and at the same time the carrier bottom is stabilized.
It_was previously stated that the fold line$ 90 of the retaining flaps could be other than.straight, as for example, curved or angled. If desired, the fold lines could be curved or angled slightly facing the end edges of the bottom panel. This tends to bias the central section 52 of the retaining flap in the direction toward its original position in the plane of the outer bottom panel flap, and in so.doing the central section is biased against the ~intervening~articles.~
_. ..... The.:dimensions..of the. retaining flap are-selected to cause the side flap sections to engage.adjacent articles in the carrier:.: The converging. fold 'lines separating -the central section_of the retaining: flaps from the side sections arevangled so that entry. of: ahe leading .-narrow end ~ of the' retainingflap ._.:: into the.: space .between adjacent articles is 'facilitated:-' r ~ ~

WRAP-AROUND CARRIER WITH ARTICLE RETAINER
F~P~a oz zne mvenm on This invention relates to article carriers and, more particularly, to article carriers having at least partially open ends.
Aa~ c~nmnd of the Invention Wrap-around article carriers are commonly designed to have ends which are either partially or entirely open. In , either case the carriers must be provided with means for preventing the articles from falling out the ends. Beverage cans, for example, are held in place partly by the tension , IO applied by the carrier blank being wrapped very tightly about them and by the engagement of the top and bottom flanges of the cans with the edges of cutouts in the side panels of the carrier through which the flanges of the cans extend. This design is .
facilitated by the fact that cans have substantially flat tops and bottoms of the same diameter as the body of the can, which allows the carrier blank to be tightly wrapped around the cans.
Problems arise when the articles are not of ,uniform dimensions, and. particularly when the articles are tapered at the bottom so as to cause the bottom portions of.the articles to be spaced apart. Wrap-around carriers for: use with tapered tubs of the type used as pudding. or margarine containers are especially troublesome because of the -difficulty in wrapping.
them .tight,ly enough to" prevent movement of the tubs :when the package is lifted and carried. Movement of:the.containers is a problem even when~the.carrier.includes side slots through which flanges,on. ,the tops of ~ the vtubs protrude,' since' such wan arrangement . ;does not , hold :.the bottom. _~p,ortions of the ' tubs tightly. in place : : ... . .. .. . _ . ~ _ ..

and would not be able to prevent movement of the bottom portions of the container toward and away from each other. Moreover, the bottom of the carton is not stable under such conditions. What is needed is an article spacing or retention means which effectively prevents the spaced bottom portions of articles from moving with respect to each other, and also prevents the bottom portions of end articles in a carrier from moving toward the open end of the carrier.
grsPf Summary of the Invention In accordance with the invention, a wrap-around carrier having a top panel and side panels is provided with a bottom panel comprised of overlapping inner and outer bottom panel flaps. The inner bottom panel flap contains an opening.near an end of the carrier, and the outer bottom panel flap includes an integral article retaining flap which is hingedly connected to the outer bottom panel flap adjacent an inner edge portion of the opening. In forming the carrier, the retaining flap is pivoted up through the opening into the interior of the carrier, .
where it engages the bottom portions of adjacent end articles of adjacent rows of articles and prevents outward movement of the articles as well as relative movement of the articles toward and away from each other.
In a preferred form of the invention the retaining flap fold line is~substantially parallel to the. end of~the carrier.
In addition, the retaining .flap includes spaced fold lines extending-transversely of the -retaining flap fold line.
Preferably, the transverse fold line s converge toward each other, producing a tapered retaining flap capable of conforming to th'e sloped bottom portions of the articles.- w~
The resulting°retaining flap-is three dimensional, 'having a central:vsection directed'toward the interior of the carrier and side.faces-.or'sections extending-betweenvadjacent end articles. Preferably, the opening through which the retainer flap_.:extendsw_is narrower than' the normal ' distance .between the side:faces;=thereby exerting a biasing-force on the / side - faces to - cause the : flap = to~ stand upright ~in the 'rpacJcage .
Because the retaining flap fits~snugly between the~spaced bottom , W092/09498 -3- r~ PCT/US91/08452 ~~~? ~:~~'.~8 (_", , . .
portions of the end articles, the articles are held in place against outward movement.
In addition to the retaining flap holding the bottom portions of the end articles in place, it also functions to interconnect the inner and outer bottom panel flaps, thus providing reinforcement 'to any other locking means connecting the bottom panel flaps.
The above and other aspects of the invention, as well as other benefits, will readily be apparent from the more detailed description of the preferred embodiment which follows.

Dera Wed Description of the Preferred Embodiment Referring to FIG. 1, a wrap-around carrier 10 comprises a top panel 12 connected along fold lines 14 to side panels 16 which generally follow the contour of the articles T in the carrier. For purpose of illustrating the invention, the articles T are shown as comprising tubs of the type used to contain pudding or margarine or the like. It can be seen that the side panels are inwardly curved at the bottom portion of the carrier as a result of being tightly wrapped around the sloped side portions of the tubs. The side panels adjacent the top panel are provided with slots 18 through which the top flanges F
of the tubs T extend. The top panel 12 is also provided with .
short extensions 20 which cover the flanges of the tubs.
A bottom panel 22 is formed by overlapped inner and outer bottom panel flaps 24 and 26. The inner bottom panel flap 29 is connected to one of the side panels 16 along fold line 28 while the outer bottom panel flap..26 is connected to the other side panel 1,6 along fold .line _30. .:'Extending up from the bottom panel .22 adjacent . the. end articles T. :in the adjacent rows'- of articles in the carrier is a retainer flap 32, which is shown in greater detail in FIG. 2. It can be seen that the retainer flap fits snugly between the angled bottom portions. of the articles T, preventing the bottomwportions from 'moving :-in -~a= direction away from the side panels 16. w -. L_; As shown -in . FIG. ; 3, wherein.: like :reference numerals to those used in FIG. i denote like elemen~s, a blank for forming the carrier 10 comprises~a substantially;rectangular sheet,34 of paperboard _or .-;other :suitable ' material; with- '-the"~~top panel section. 12, being in the .center. of~the.aheet :.and. the. other panel .
sections described above being successively connected.along-the fold lines referred;to above. . Thus thevfold.lines:l9~connecting the top 'panel 12 to the side panels 16 are separated"from each .

other by portions defined by the elongated slits 36 and the short connecting slits 38 which correspond to the extension of the top panel overlying the tub flanges in a carrier formed from the blank. The slots 18 of FIG. 1 through which the tub flanges protrude are formed when the side panels are folded down from the top panel, and the width of the slot corresponds to the length of the short slit 38.
In order to form a carrier from the blank 39, the blank is wrapped around the tubs or other articles to be packaged with the inner and outer bottom panel flaps 24 and 26 in overlapping relationship. The bottom panel flaps 24 and 26 are shown in FIG. 4 as they would appear after being folded in from side panels 16 about the fold lines 28 and 30 just prior to being moved into overlapping relationship. Referring to both FIGS. 3 and 4, the retaining flaps 32 are connected to the outer bottom panel flap 26 along fold lines 40 which are located between the end edges 42 of the flap 26 and the midpoint of the flap. The fold lines 40 are shown as being substantially straight and , parallel to the end edges 42, although they-may be slightly curved or angled as discussed in greater detail hereinafter. A
slit 44 which is also substantially parallel to the end edges 42 of the outer bottom panel flap 26 and which is located between the fold lines 90 and the_end edges 42, forms the opposite edge of the. retainer flap 32.. The sides of the:.retainer flap are defined by slits 46_which extend from the ends of-slit 44 transversely of the end edges 42.toward the interior of the carrier, and by angled slits-48 connecting.the slits 46 and the ends of the fold lines 40. The. retainer flap 32 further includes two- fold -lines 50 ..which extend from the ends of the fold.line 90.and converge.to.the slit 44;.:intersecting the slit ~-44.~. at spaced; ~ points . :' . It.;.._ can be . seen w .that the resulting retaining flap ..;is.;,made... up of 'a central- : face or -: section =-'~52 bounded by, the. fold .lines.,-40 and 50 : and . the slit 44, and of ~ two side ,facesl..or..sections-;.54_ bounded by the s?,-its 44; 46- and 48 and ~_ : .. , _ . . , , the fold lines 50.. . :~' , ._: .. ._,.. __.__ _.._. ..::~,-~ ...
.,..The inner_.bottompanel , flap x24 includes :two modified ~T-shaped .openings or slots 56_.located -so :as.. o be aligned with the retainer flaps 32 when the inner and outer bottom panel flaps WO 92/09498 :i r-~:
are overlapped to form the bottom panel of the carrier. Each cutout or slot 56 comprises a relatively wide elongated slot , portion 58 extending from a transverse slot portion 60.. The slot portion 58 is spaced from and extends transversely of the nearest panel end edge 62, while the slot portion 60 extends outwardly of the slot portion 58 at the end thereof farthest from the panel end edge 62. The slot portion 60 extends generally parallel to the end edge 62. The slot portion 58 is defined by an edge 64 which is spaced from and parallel to the panel end edge 62 and by edges 66 which converge toward the interior of the carrier. The slot portion 60 is defined by an ' edge 68 which~is also parallel to the panel end edge 62 and by edges 70 which connect the edge 68~to the slots 66 at their closest spacing. The angular portion of the inner bottom panel flap 24 adjacent the intersection of edges 66 and 70 comprises opposing tabs 72.
Still referring to FIGS. 3 and 4, the bottom panel flaps are designed to be mechanically connected in a manner generally known.in the prior art. The outer bottom panel flap 26 is connected to an end margin flap 79 along fold line 76. The fold line 76 is interrupted in the central portion by a slit defining a male locking tab 78 and on either side of the tab 78 by the , slits 46 which.coincide.with the fold-line 76. The margin flap 74 also.contains a centrally located~locking opening~~80 the interior edge-_82 .of which extends a substantial distance beyond the. side .edges of :the .opening.
The inne r:bottom panel'flap 24-'contains a centrally located_male locking tab 89.'~defined by end slit 86, side slits 88, ~ angled slits r90 whichrforin ~a neck portions,' ~andr foldline '92 .
; ..The _ locking :, tab .84 . is part of a la=ger"tab' or flap 94 vwhich is connected to the . inner =bottom ~ flap 30 -along ~~fold.,-hine 96 'and _ which.~,further is ~defined:by slits 98 extending from the ends'-of the fold line 96 to=the:slits 90 ofvthevlocking tab 84. ~' ,;~ To ; lock -.the ~. bottom panel ~~ flaps = together; ''wthey-'~are positioned in overlying relationship, with the end~wmargin flap _v-74 .of. the outer'_bottom panel-flap ~aind'the"tab'~99 of 'the inner ...bottom panel .flap being ~-folded%back=a's =illustrated'~in FIGS:' S
and 6. As shown, a smallportion of one end ~of the slot 60 is -xr..;.~
.-.
visible below the folded-back margin 79. The outer bottom flap 26 is then moved to align the locking tab 78 of the margin 74 with the locking edge 86 of the inner bottom flap 24. By folding the margin flap 74 back to its original position the locking tab 78 engages the locking edge 86 and the underside of the inner bottom panel flap 24 to mechanically hold the bottom panel flaps together as the primary lock of the bottom panel.
Th tab 94 is then folded back to its original position and the locking tab 89 is folded about its fold line 92 into the locking opening 80 through the slit 82 to effect a secondary lock. This arrangement is illustrated in FIGS. 7 and 8.
It can be seen in FIG. 7 that when the bottom panel flaps are locked together, the retaining flaps 32 are positioned directly over the openings or slots 56. .Note that the openings _ '15 56 are shown in dotted lines in FIG. 7 while the retainer. flaps 32 are shown in solid lines, 'depicting the slits, and in dot-dash lines, depicting the fold lines of the retaining flaps.
Pressure exerted on the central body sections 52 of the retainer flaps by an externally located movable punch or rod element, not shown but which will be understood by those skilled in the art preferably to be an operating element in an automatic packaging machine, will cause the retainer flaps to be pivoted up about their fold.lines 40 and pushed up into the interior of the carrier through the openings 56 in the inner bottom.panel flap 29. A typical intermediate position of the retaining flap as it would.appear, during this movement.is illustrated in FIG. 9, ' which shows - the. bottom of .ahe . retaining flap, and in .FIG : 10, ,which. shows.,,the. upper.portion.of the retaining .flap as it ' - emerge.s,_-into the interior. of:~the carrier.v.: It: will-.be seen that movement,.of~the-.retainer~flaps through.the~wslots in this manner .causes.the~.side retainer:; sections 59. to <fold,about:their fold ' .lines 50=:as -a :result ~of:;their contact with . he.-edges -~of =the . elongated,; slot portions .58 .- In .particular,': it~ swill . be seen '-that .

~S~'~ k.r;;~f,~
to the combination of stiffness and flexibility o~ the paperboard material. The tabs thus exert a biasing force against the side sections.
Continued pivoting movement of the retaining flaps about the fold lines 90 will continue to fold the side sections 54 of the retaining flap until the retaining flap reaches its fully extended position in the interior of the carrier. This position, as illustrated in FIGS. 2 and 11, can be seen to be substantially vertical. The continued urging of the tabs 72 .
against the side sections 54 helps to maintain the retaining flaps in their fully elevated position. As best shown in FIG.
11, the side sections 54 are located so as to contact the sides of the tubs or other articles T so that the tubs are securely held between the side panels of the carrier and the retaining flap. The articles are thus divided and separated and at the same time the carrier bottom is stabilized.
It_was previously stated that the fold line$ 90 of the retaining flaps could be other than.straight, as for example, curved or angled. If desired, the fold lines could be curved or angled slightly facing the end edges of the bottom panel. This tends to bias the central section 52 of the retaining flap in the direction toward its original position in the plane of the outer bottom panel flap, and in so.doing the central section is biased against the ~intervening~articles.~
_. ..... The.:dimensions..of the. retaining flap are-selected to cause the side flap sections to engage.adjacent articles in the carrier:.: The converging. fold 'lines separating -the central section_of the retaining: flaps from the side sections arevangled so that entry. of: ahe leading .-narrow end ~ of the' retainingflap ._.:: into the.: space .between adjacent articles is 'facilitated:-' r ~ ~

Although the mechanical locking means for the bottom panel flaps need not be limited to the type shown, it is S preferred because of its proven ability to hold the panel flaps in locked condition against severe stresses and because it is especially suitable for use with the retaining means of the invention. For example, even though the retaining flaps are required to be located at a point in the outer bottom panel flap immediately adjacent the locking margin, by making the outer edge of the retaining flap coincide with the fold line of the locking margin 74 of the outer bottom panel flap, both the retaining flap elements and the locking tabs can be properly located with respect to each other.
Although not illustrated, it will be understood that the top panel may be provided, with handle openings if desired, to facilitate lifting and carrying.
It should now be apparent that the invention need not be limited to all the specific details described in connection with the preferred embodiment, but that changes to certain features of the preferred embodiment which do not alter the overall basic function and concept of the invention may be made without departing from the spirit and scope of the invention, as defined in the claims. ..
