US. Cl. 206-65 18 Claims ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTION Many tubular carriers are in present use which have weakened areas for receiving the heels of associated containers, such as glass bottles, for example, to hold such bottles in position. However, each weakened area in each present carrier has a comparatively long skirt formed therein which creates numerous problems during the handling of present carriers and their associated bottles. In particular, the long skirts provided in present carriers provide less protection for the heel of an adjoining bottle, extend out further from the side wall of an associated carrier, and tend to hang up upon being lowered into an associated shipping carton upon shipping each carrier from a bottling plant and subsequently continue to create problems by hanging up against adjoining carriers as well as other adjoining structures.

SUMMARY This invention provides an improved carrier for bottlelike containers and an improved blank for making same wherein such carrier has a plurality of weakened areas provided in its side walls and each weakened area includes a comparatively short skirt which hugs tightly against the heel of an adjoining container to provide optimum protection for such heel and adjoining container and assures that the terminal lower edge of the skirt will not hang up during the initial packaging of the carrier in a shipping carton or during subsequent handling of the carrier and its associated containers during merchandising of the product contained within such containers.

Other details, uses and advantages of this invention will become apparent as the following description of the embodiment thereof presented in the accompanying drawings proceeds.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings show a prior art carrier and a present preferred embodiment of this invention, in which:

FIGURE 1 is a perspective view of an exemplary prior art carrier which has a plurality of eight bottles positioned therewithin and wherein the heel of each bottle is held in position by an associated weakener area provided in an adjoining side wall of the carrier;

FIGURE 2 is a fragmentary view looking normally toward one of the weakened areas provided in the side wall of the carrier of FIGURE 1;

'ice

FIGURE 3 is a fragmentary perspective view particularly illustrating a comparatively long skirt comprising the weakened area of the prior art carrier to highlight the ease with which such elongated skirt is susceptible to damage;

FIGURE 4 is a perspective view illustrating two prior art carriers in position within a shipping carton and particularly illustrating one of the problems presented by such prior art carriers in attempting to place' a third carrier in position within the shipping carton;

FIGURE 5 is a perspective view of the improved carrier of this invention particularly illustrating the tightly hugging skirt comprising each weakened area provided in the carrier for receiving the heel of an associated bottle;

FIGURE 6 is a fragmentary perspective view particularly illustrating the manner in which a given weakened area in the carrier of FIGURE 5 receives the heel of an associated bottle and the manner in which the skirt defined in such weakened area is held snugly against the DESCRIPTION OF ILLUSTRATED EMBODIMENT In order to facilitate the understanding of this invention reference is now made to FIGURES 1-4 of the drawings which depict a prior art carrier 20 and problems associated therewith. In particular, it will be seen that the carrier 20 is in the form of a tubular carrier for carrying a plurality of eight containers or bottles each designated generally by the same reference numeral 21. The carrier 20 has a bottom wall 22, a top wall 23, and a pair of oppositely arranged side walls 24A and 24B. The bottles 21 are arranged within carrier 20 in two parallel rows having four bottles in each row and a plurality of three finger receiving openings each designated by the same reference numeral 26 are provided in top wall 23 and each finger receiving opening 26 is arranged to enable insertion of the fingers of one hand therewithin for easy carrying of the carrier.

The carrier 20 has a plurality of substantially circular openings 30 provided in its top wall and each opening 30 is adapted to receive the neck 31 of an associated bottle 21 therethrough. The carrier 20 also has a plurality of weakened areas provided in the lower portion of each of its side walls 24A and 24B and the weakened areas in each side wall 24A and 24B are substantially identical and are each designated by the reference numeral 33. Each weakened area 33 is adapted to receive the heel 34 of an associated bottle 21 therewithin to prevent the lower end portion of the bottle 21 from moving with respect to the carrier 20. 'Each weakened area 33 provided in carrier 20 has a comparatively long skirt designated by the numeral 35 which is defined at its lower edge by an inverted substantially U-shaped cut 36 and a pair of comparatively elongated cuts each designated by the numeral 37 extending upwardly and in an opposite,

direction from the downwardly extending leg portions of the U-shaped cut 36. The cuts 36 and 37 create a substantial length to the skirt 35 which extends outwardly of an inclined portion 40 provided in each side wall 24A and 24B, and each inclined portion 4'0 adjoins bottom 3 wall 22 and defines the lower end portion of its associated side wall.

The comparatively long skirt 35 of the prior art carrier 20 is susceptible to damage upon being caught against an ajoining carrier or, as illustrated in FIGURE 4 of the drawings, against an edge 42 of an associated shipping carton 43 upon placing a plurality of carriers 20, such as three carriers, in the shipping carton or mother carrier 43 to transport the carriers and associated bottles from a bottling plant, for example.

Each of the comparatively long skirts 35 normally stands away from its associated inclined surface 40 as shown at 44 in FIGURE 1 so that it is easily caught against adjoining structures; furthermore, upon being caught against a carrier or a carton in the manner described above, it is easily bent and deformed so that it extends even further away from its associated side wall 24A or 24B as shown at 45 in FIGURE 3. Thus, it will be appreciated that with the comparatively long skirt 35 provided in carrier 20 a considerable number of problems are created in handling carrier 20 during the packaging of such carrier within shipping carton 43 as well as during the stacking of a plurality of carriers 20 adjoining each other in a retail establishment.

Further, the prior art carrier 20 is of the type commonly used for packaging throwaway glass bottles 21 and the comparatively long skirt 35 exposes a comparatively large area of the heel 34 of the bottle 21 and provides less protection for such heel. The problem is aggravated because throwaway glass bottles are of a more fragile construction which results in considerable breakage of bottles and loss of the product contained therein, as well as creating safety problems due to the numerous sharp pieces of glass created by such breakage.

Thus, it is seen that the prior art carrier 20 is deficient in that it is easily snagged on adjoining structures and thereby produces numerous problems in shipping and handling and provides comparatively little protection for the heel of bottles carried therewithin.

Reference is now made to FIGURES -10 of the drawings wherein an exemplary embodiment of the improved carrier of this invention, designated generally by the numeral 50, is illustrated. The improved carrier 50 provides optimum protection for a plurality of containers or hottles carried therewithin and for ease of description such bottles will again each be designated generally by the reference numeral 21, the neck portion of each bottle 2l will be designated by the numeral 31, and the heel of each bottle 21 will be designated by the reference numeral 34.

The carrier 50 has a bottom wall 51, a top wall 52, and a pair of oppositely arranged side walls 53A and 53B which are substantially identical except for a pair of easy-open tear strips provided in one of such side walls; therefore, for ease of presentation corresponding component parts of the side walls 53A and 533 Will be designated by the same reference numerals. Each of the side walls 53A and 53B has an inwardly inclined strip which is of substantially rectangular outline and designated by the reference numeral 54 and, as will be apparent from the drawings, each inclined rectangular strip 54 is arranged adjoining the bottom wall 51.

Each side wall 53A and 53B has a plurality of substantially identical weakened areas each designated generally by the reference numeral 55 provided therein and each weakened area 55 has a substantially triangular peripheral outline. The weakened areas 55 are arranged adjacent the lower end portion of their associated side walls and each weakened area 55 is adapted to receive the heel 34 of a bottle 21 thereagainst to hold the heel 34 firmly in position within the carrier 50. The top wall 52 of carrier 50 has a plurality of circular openings 60 provided therein and each opening 60 is adapted to receive the neck 31 of an associated bottle 21 therethrough so that a bottle 21 is supported at its upper end by extending its neck 31 through an associated opening in the top wall 52.

Each substantially triangular weakened area 55 comprises an expansible skirt 62 which is slightly expanded outwardly upon receiving an associated heel 34 of a bottle 21 thereagainst. Each expansible skirt "62 has a lower edge 63 which is held snugly against its adjoining heel 34 and lies substantially coplanar with its associated 1'ec tangular strip 54 so as to provide maximum protection for such heel as well as assure that the lower edge 63 is maintained substantially intact during handling of the carrier 50 and its associated bottles 21.

In particular, it will be appreciated that with the edge 63 held snugly against an associated heel 34 and approximately coplanar with its inclined rectangular strip 54 it is a simple matter to stack one carrier 50 against and/0r between adjoining carriers or insert carrier 50 in a shipping carton or mother shipper 43 as illustrated in FIG- URE 7. Further, there is little likelihood that skirt 62 of carrier 50 will be caught against edge 42 of shipping carton 43, for example. The shipping carton 43 shown in FIGURE 7 with the improved carrier 50 has been identified with the same reference numeral 43 as the carton shown with the prior art carrier and the illustration of FIGURE 7 is similar to the illustration of FIGURE 4 to highlight that the carrier 50 of this invention is readily and easily inserted in position within shipping carton 43 without any tendency for its skirt 62 to hang up.

As seen particularly in FIGURES 8 and 10 of the drawings, each triangular area 55 is defined by a base indicated at 65 which adjoins bottom wall 51 so that a substantial part of its triangular outline, and in particular the lower base portion of its triangular outline, is provided in an associated rectangular strip 54. Each triangular area also has a pair of side edges extending upwardly from the base 65 in a substantially converging manner and each side edge is designated by the reference numeral 66. Each side edge 66 is comprised of a lower portion 70* defined by a plurality of spaced apart slits arranged approximately in a rectilinear path and an upper portion 71 aligned with lower portion 7 0 and defined by a score line which terminates at a point 72 defining the apex for the associated triangular weakened area 55.

Each weakened area 55 also has a roughly U-shaped cut designated generally by the numeral 73 which extends substantially across the full width of the triangular weakened area 55 and the U-shaped cut 73 has a central base portion 74 which is arranged substantially parallel to bottom wall 51 and in spaced apart relation therefrom and a pair of leg portions each designated by the same reference numeral 75 extending from the opposite end edges of the central base portion 74. The leg portions 75 diverge from each other and each leg portion 75 diverges from its associated end edge of the central base portion 74 and each terminates in an arcuate end 75A which, in elfect, defines the intersection of one end of base 65 of the triangular weakened area 55 and its associated upwardly converging side edge 66.

Each U-shaped cut 73 defines a tab 76 which is arranged substantially coplanar with bottom wall 51 of carrier 50 upon placing an associated heel 34 of a bottle 21 within the particular triangular wveakened area 55. Each triangular weakened area 55 also comprises a pair of symmetrically arranged slits each designated by the same reference numeral 80 and the slits 80 extend from opposite end edges of the central base portion 74 of U- shaped cut 73 toward an associated converging side edge 66 of the triangular outline weakened area 55. Each slit 80 has a small length as compared to the distance between an end of base portion 74 and an associated side edge 66.

The central portion 74 of the U-shaped cut 73 and the slits 80 cooperate to define the lower edge 63 of skirt 62 and the comparatively small length of slits 80 assure that the lower edge of the skirt 62 is held snugly against its adjoining heel 34 so as to preclude the possibility that the skirt 62 could be caught against an adjacent carrier or against an edge of a shipping carton, or the like.

Each slit 80 is made in an associated inclined rectangular strip 54 so that it is arranged at an acute included angle with an adjoining leg portion 75 of U-shaped cut 73. Further, it will be seen that each slit 80 is made in its associated rectangular strip 54 so that its terminal end is positioned immediately adjacent the center of rectangular strip 54 thereby further assuring that the lower edge of skirt 62 is arranged inwardly of the vertical portion of its associated side wall. In particular, it will be seen that the lower edge 63 of each skirt 62 is arranged substantially coplanar with rectangular strip 54, as previously mentioned, and considerably within the vertical plane within which the main portion of its associated vertical side wall is arranged.

The carrier 50* is a wraparound tubular carrier which has open ends and has a separator 82 which extends upwardly from the bottom wall 51 to separate the lower end portion of the bottles 21 to prevent the bottles in one row from striking the bottles in an adjacent row. In addition, it will be seen that the carrier 50 has a plurality of three finger receiving openings in its top wall 52 comprised of a central circular opening 84A and a pair of semicircular openings 84B arranged on either side of central opening 84A. The openings 84A and 84B are adapted to receive the fingers of one hand therein to enable easy grasping and carrying of the carrier 50.

As will be appreciated particularly from FIGURES 5, 6, and 9 of the drawings, the bottle 21 is of right circular cylindrical configuration along the main portion thereof, its upper neck 31 is substantially frustoconical, and its heel 34 is of roughly frustoconical configuration and constructed so that the right circular cylindrical main portion of the bottle 21 fiows smoothly to define the heel portion 34. Also, it will be seen that the inclined rectangular strip 54 is arranged so that it roughly follows the contour of the main portion of the frustoconical heel 34.

The carrier 50 is in the form of a wraparound carrier having a tubular configuration, as previously mentioned and having open ends. The carrier 50 may be fastened in position in an automatic assembly operation wherein a single piece rectangular blank comprising carrier 50 is fastened in position by lowering it toward bottles 21 so that the necks 31 of bottles 21 extend through openings 60 with the bottles properly arranged in two parallel rows on an assembly line. With the carrier 50 thus positioned around the necks 31 it is then wrapped around the bottles 21 and suitably fastened utilizing integral mechanical locking ta-bs comprising carrier '50 and such tabs are inserted through cooperating cuts provided in the carrier bottom wall after first extending the separator 82 between the two rows of bottles comprising the package construction around which carrier 50 is wrapped. The detailed description of the fastening tabs and associated cuts will be made later in this specification in connection with the description of the single piece blank used to make carrier 50.

Inasmuch as carrier 50' is, in effect, wrapped around and fastened in position around a plurality of bottles 21, easy-open means is provided for opening the carrier 50 and such easy-open means is provided in the form of a pair of elongated tear strips designated by the reference numerals 85 and 86 and provided in at least one of the side walls. The tear strips 85 and 86 are of known construction and in this example of the invention are defined in only side wall 53A and formed by a plurality of cooperating aligned slits provided in the side wall 53A.

Carrier 50 can be formed in any suitable manner and made from any suitable foldable material. It is preferably formed from the blank 90 illustrated in FIGURE 10 of the drawings. Blank 90 is made of paperboard, or the like, and may have a side such as the exposed surface thereof laminated with metallic foil, such as aluminumcontaining metallic foil, or the like, suitably colored, embossed, imprinted, or remaining plain, as desired.

The description of blank will proceed by describing primarily those structural portions which were not previously described in detail in connection with the description of the carrier 50. However, where a previous detailed description was made in connection with the carrier, such description will not be repeated in connection with the blank and corresponding component portions of blank 90 will be designated by the same reference numerals as in carrier 50.

Blank 90 is of rectangular peripheral outline and is suitably cut and scored and adapted to be assembled to define the resulting carrier 50 of this invention and comprises a plurality of parallel spaced apart score lines designated by the numerals 91, 92, 93, and 94 which define the top wall 52 between score lines 92 and 93, side wall 53A between score lines 91 and 92, and side wall 53B between score lines 93 and 94. The blank 90 also has an extension flap extending outwardly of score line 91 and another extension flap 101 extending outwardly of score line 94. The extension flaps 100 and 101 are adapted to be folded into a common plane and suitably fastened together to define bottom wall 51 and the extension flap 101 also has a rectangular terminal end portion 82 which extends outwardly of another score line 103 and the terminal end portion 82 is adapted to be inserted in position as a separator between a pair of parallel rows of bottles 21 in the resulting carrier 50 as previously described in connection with the detailed description of the carrier 50.

As will be apparent from FIGURE 10 of the drawings extension flap 100 has a plurality of three centrally arranged and comparatively large locking tabs 106 defined therein and each locking tab 106 is defined by a substantially arrowhead-shaped cut 107. In addition a pair of smaller locking tabs 110 are provided adjacent the opposite ends of the extension flap 100 and the locking tabs 110 are defined by an arrowhead-shaped cut 111 which is similar to the arrowhead cut 107 and of smaller size.

A plurality of cooperating U-shaped cuts are provided in extension flap 101 and include three centrally arranged U-shaped cuts each designated by the same reference numeral 113 and a pair of smaller U-shaped cuts each designated by the numeral 114 and arranged adjacent the opposite ends of extension flap 101. The cuts 113 and 114 are adapted to receive an associated arrowhead-shaped locking tab 106 and 110 respectively upon wrapping the carton 50 made from blank 90 around its associated bottles 21 and then pushing the locking tabs in position to provide a positive fastening action which does not require separate fasteners such as staples, adhesives, or' the like. The fastening action may be achieved in a known manner and utilizing automatic fastening means such as push rods which engage the locking tabs 106 and 110 and push them in locking position through their associated U-shaped cups after first folding separator 82 in position, then folding extension flap 101 against its row of bottles 21, and then placing extension flap 100 against and outwardly of extension flap 101 and pushing the locking tabs in locking position.

As previously described in connection with the description of carrier 50 three finger receiving openings are provided in the top wall 52 and defined by a central cutout or opening 84A and a pair of openings 84B on either side thereof. Each finger receiving opening 84B is defined by a C-shaped cut 115 which has a score line 116 extending between the terminal ends of the cut 115 so as to define a foldable flap 117 which is folded inwardly to define an associated opening 84B.

As previously mentioned a plurality of openings 60 are provided in top wall 52 and as Well be apparent from FIGURE 10 a pair of slits each designated by the same reference numeral 122 is provided in association with each opening 60 to assure that the resulting carrier 50 may be installed in position about its associated bottles 21 without tearing. Only a few representative slits 122 have been designated in FIGURE 10.

The blank 90 has a pair of tear strips 85 and 86 provided in its side wall 53A. However, as previously indicated it will be appreciated that tear strips may be provided in side wall 538 instead of side wall 53A or in both side walls 53A and 53B.

The rectangular strip 54 provided in each side 53A and 53B was previously described in connection with carrier 50. The strip 54 for side wall 53A is defined by score line 91 and a score line 120. Similarly the strip 54 for side wall 53B is defined by score line 94 and a score line 121.

Each side wall also has an inclined portion provided in the upper part thereof and each inclined portion is defined by a strip which is designated by the same reference numeral 124. The strip 124 in side wall 53B extends between score line 93 and a score line 125 while the strip in side wall 53A is arranged between score line 92 and the aligned cuts defining the upper edges of the tear strips 85 and 86.

As will be apparent from FIGURE 10 of the drawings the score lines 91 and 94 defining the lower edge of side walls 53A and 53B representively are discontinuous and comprised of a plurality of sections aligned in a substantially rectilinear path. Each score line 91 and 94 is interrupted by a plurality of U-shaped cuts 73 and each U-shaped cut 73 comprises an associated weakened area 55. In addition, the score lines 120 and 124 are each defined by a plurality of aligned discontinuous sections arranged in a substantially rectilinear path and such sections are arranged on opposite sides of each weakened area 55.

Each substantially triangular weakened area 55 further comprises a pair of upwardly converging cuts each designated by the same reference numeral 127 which extend upwardly from a location arranged inwardly of and spaced above the terminal ends of an associated slit 80. The upwardly converging cuts 127 comprise an upper portion of the outwardly expansible skirt 62. In addition, a longer cut 130 is provided between the cuts 127 in each triangular area 55 and the cut 130, in effect, bisects the angle defined by the cuts 127 and has a portion which extends above the apex shown at 72 of its associated substantially triangular weakened area 55.

Thus it is seen that the improved carrier 50 made from blank 90 provides optimum protection for containers such as glass bottles carried therewithin and may be readily transported and handled with minimum likelihood of snagging weakened areas provided therein for receiving the heels of its associated bottles to thereby avoid problems of the type encountered in handling presently known carriers.
