3,540,581 11/1970 Koolnis 229/17 B X Primary Examiner-George F. Mautz Attorney, Agent, or Firm-Guy A. Greenawalt [57] ABSTRACT A package of beverage cans or similar articles wherein the articles are enclosed in multiple row arrangement in a tubular container which forms a carrier and which is fabricated from a blank of foldable sheet material, the blank being cut and scored to provide top, bottom and side walls with pairs of closure forming flaps at the opposite ends of the side walls which closure flaps are adapted to be hinged into end wall closing position and retained in such position by interlocking tongue and slot arrangements in overlapping margins thereof and provision being made for a tear out opening at the bottom of one end wall for dispensing the cans one at a time.

8 Claims, 7 Drawing Figures CARTON This invention relates to packaging and is more particularly concerned with improvements in cartons or carriers for enclosing a plurality of articles such as beverage filled cans or the like.

In the packaging of articles, such as canned beer, soft drinks and the like, various types of containers have been employed, generally in the form of carriers, with provision for accepting a predetermined number of the cans, for example, six, eight or twelve, arranged in row formation. One type of packaging container or carrier which has been employed has been in the form of an open ended tube or sleeve with provision for retaining the cans against excessive movement therein or accidental removal through the open ends. in another packaging arrangement tubular packaging containers have been provided which have some means for closing the ends. either wholly or in part, so as to confine the cans and prevent accidental removal from the package. Where end panel closures have been employed, sealing, generally with hot melt adhesives so as to eliminate the long compression sections required with cold adhesives, has generally proven to be too costly in terms of material and the skilled labor required. it is a general object, therefore. to provide a carrier or carton of the sleeve type with end closures, which is of improved construction and which is more economical in use while retaining the advantages of similar carriers heretofore employed.

A more specific object of the invention is to provide a package arrangement for articles such as canned beverage products, or the like, wherein a multiple unit package is obtained which comprises a plurality of the articles in row or tier formation and an improved wrapper or carrier sleeve of tubular form with end or side wall closure panels which have locking and latching el ements in overlapped margins adapted to be interengaged so as to hold the closure panels in wall closing and article confining position.

A further object of the invention is to provide a pack age arrangement for canned beverages, or similar articles, wherein a tubular carrier for a multiplicity of the cans is formed from a generally rectangular blank which is cut and scored to provide integrally connected top. bottom and side wall members, and end wall clo sure panels or flaps which are hinged to the side walls and folded into end wall closing relation with overlapping margins in which locking and latching elements are provided which hold the flaps in closure forming position and with minimal exposure of flap edges which would be subject to snagging in shipping and handling.

Another object of the invention is to provide a carrier package for canned beverages or the like wherein the packaging container is fabricated from a cut and scored blank of paperboard or other suitable sheet material with top wall forming panels which overlap and which have hand holes or openings cut in overlapping marginal portions wherein the overlap is extended so as to provide reinforcing areas at each side of the handle openings and strengthen the material at the corners of the handle openings where tearing is likely to occur.

A further object of the invention is to provide a carrier package for canned beverages, or similar articles, which are in multiple row or tiered arrangement, wherein the packaging container is formed from a cut and scored blank of foldable sheet material with connecting top, bottom and side walls and hinged closure panels for closing the ends which are connected by cooperating latch and lock elements in overlapping margins and wherein there is provided a tear out arrangement for releasing successive articles through a roll out discharge opening adjacent the bottom of the package.

A still further object of the invention is to provide an improved article carrier construction of the type wherein a plurality of cans or similar articles are enclosed in a wraparound blank having hingedly connected bottom, side and top wall panels, with the top wall formed by a pair of panels which are overlapped and provided with hand holes arranged therein so as to be reinforced at the points of greatest stress when the package is grasped and carried thereby to minimize tearing at such points.

These and other objects and advantages of the invention will be apparent from a consideration of the package of canned beverages and the method of forming the same which is shown by way of illustration in the accompanying drawings wherein:

FIG, 1 is a perspective view of a package comprising twelve cans in 4 X 3 row or tiered arrangement and en closed in a wrapper or carton which embodies the principal features of the invention;

FIG. 2 is a top plan view of the package shown in FIG. 1;

FIG. 3 is an elevational view showing one end of the package of FIG. 1;

FIG. 4 is a partial perspective view illustrating a can dispensing feature which is embodied in the package;

FIG. 5 is a plan view of a blank of foldable sheet material which is cut and scored to form the carrier type carton for the package shown in FlG. 1;

FIG. 6 is a plan view of the completed carton or carrier in flat folded or collapsed condition; and

FIG. 7 is a perspective view of the carton in set up or opened up condition, with the closure flaps at one end open for end loading of an assembly of cans therein.

The package unit 10 which is illustrated in FIGS. 1 to 4 comprises a plurality of beverage cans C arranged in three rows of four cans each and enclosed in a tubular wrapper sleeve, carton or carrier 12 which is formed from a cut and scored blank of paperboard or similar foldable sheet material and which has opposite ends or sides closed by pairs of hinged panels, with each pair of the closure panels having overlapped marginal portions connected by interengaging locking and latching elements of a character which hold the panels securely with minimal exposure of loose flap edges which are subject to snagging in handling and shipping.

The package 10 and the method of fabricating the same will be best understood by reference first to FIG. 5 wherein there is illustrated a wrapper blank W which is cut and scored for fabricating the package of FIGS. 1 to 4. The blank W is preferably formed of paperboard of suitable weight or gauge which may be cut in multiples from a wide web with maximum economy. The blank W is divided by parallel, longitudinally spaced, transverse score lines l6, 18, 20 and 22 into a series of connected blank sections or

panels

24, 26, 28, 30 and 32. The center panel 28 between transverse score lines 18 and 20 constitutes a bottom wall panel in the final package, while the adjoining blank sections or

panels

26 and 30 which extend between the transverse score lines l6, l8 and 20, 22, respectively, are scored on laterally spaced, parallel, longitudinally extending

lines

34, 34' and 36, 36' so as to provide side wall forming 3

panels

38, 40 and associated end

wall forming panels

42, 42' and 44, 44'. The two blank end sections or

end panels

24 and 32 co-operate in forming the top wall structure of the package.

The two top

wall forming panels

24 and 32 each have a dimension in the lengthwise direction of the blank which is greater than the corresponding dimension of the bottom wall forming panel 28. The

panels

24 and 32 have overlapping portions in the set up form of the carton or carrier (FlG. 2) and each of these panels is provided with a pair of hand hole or finger

hole forming apertures

46, 48 and 50, 52, respectively. The

endmost apertures

46 and 50 are provided by cutting on a generally U-shaped line inwardly of the

end edges

54 and 56 of the blank. These apertures and also apertures 48 and 52 extend laterally of the blank in a symmetrical manner about the longitudinal center line aa. In panel 32 narrow flaps 58, 58' are provided along the adjacent edges of the

apertures

50, 52 with score lines 60, 60' on which they can fold when the carrier is grasped for carrying. The

apertures

48 and 52 are spaced the same distance relative to the

apertures

46 and 50 and when the

panels

24 and 32 are overlapped in forming the car rier the

hand hole apertures

46, 50 and 48, 52 are brought into alignment. The panel 32 forms the innermost panel in the set up top wall structure and

small flaps

58, 58 are adapted to fold on the score lines 60, 60' so as to reinforce the area 62 (FIG. 2) between the two handle openings and protect the fingers of the user against the cutting action of a raw edge.

The two side and end wall forming

blank sections

26 and 30 which are divided by the

score lines

34, 34' and 36, 36' to provide the side

wall forming panels

38, 40 and the associated end

wall forming panels

42, 42' and 44, 44' are symmetrical about the longitudinal center line a-a, except for a dispensing feature which is hereinafter described, and the parallel,

longitudinal score lines

34, 34' and 36, 36 are equally spaced from the longitudinal center line a--a. The end wall forming panels 42 and 42' are cut and scored in an identical manner except for the dispensing feature referred to and likewise the end wall forming panel extensions 44 and 44' are cut in the same manner except for the dispensing feature. End

wall forming panels

42 and 42 each have a lock and

latch panel

64, 64 in the free margin which is separated from the remainder of the associated panel along the score line 66, 66'. Each locking panel 64, 64' has a pair of latch forming tabs or tongues 68, 68' cut in the outer margin which extend from the free marginal edge 70, 70' while a pair of cooperating locking tabs 72, 72' are cut in the panel material along the hinge lines 66, 66' and in oppositely disposed relation with the respective latching tongues 68, 68'. The end wall forming panels 44 and 44' are provided in their outer marginal portions with pairs of apertures 74, 74' which are properly spaced and of the proper size to receive in locking and latching relation the locking and

latching elements

72, 72 and 68, 68' provided on the hinged panels 64, 64'. The locking and latching panels 64, 64' and associated elements may be of the same character as the locking and latching arrangement which is described for the bottom wall pan els in US. Pat. No. 3,168,194, dated Feb. 2, 1965 and in US. Pat. Nov 3,589,593, dated June 29, l97l.

Side wall panels

38 and 40 and the associated

end wall panels

42 and 44 at one side of the blank W are provided with an article dispensing feature which takes the form of tear out

areas

76, 76 in the

panels

38 and 40 and areas 78, 78' in the end

wall forming panels

42 and 44, respectively. The panels or tear out areas 76 and 76' are provided by the cutting in the longitudinally spaced corners of the

panels

38 and 40 on the inwardly curved or bowed cutting lines or tear lines 80, 80', each of which comprises a series of spaced J- shaped cuts for weakening the material so that it may be readily torn along the lines 80, 80'. The tear out areas 78, 78' which are on the opposite sides of the hinge forming

score lines

34 and 36 are provided by diagonally, inwardly extending tear lines 82 and 82'. In addition, the

panels

42 and 44 are each scored on the curved lines 84 and 84', the former extending to the score line 66 of the locking panel and the latter terminating short of the free side edge of the wall forming panel 44. The score lines 84 and 84' extend from the intersection of the tear lines 80, 80' with the

tear lines

82, 82.

As shown in FIG. 5, the blanks W are cut so as to provide for nesting across a wide web, enabling the operator to obtain a maximum number of cut and scored blanks from the web material. For

maximum nesting panels

24, 28 and 32 have a dimension transversely of the blank which is less than the distance between the

score lines

34, 34' and 36, 36' which determine the over-all dimension of the side walls and of the carrier in the lengthwise direction.

in fabricating the carrier or carton, the cut and scored blank W is folded first on the transverse score line 22 and then on score line 18 so as to bring the panel 32 underneath the panel 24 which is provided with a suitable adhesive as indicated at 86. [n overlapping the

panels

32 and 24

hand hole apertures

46 and 48 are aligned with

apertures

50 and 52 which results in a relatively wide area 62 between the hand holes for grasping the carrier and also in reinforcement of the

points

88, 88' and 90, 90' (FIG. 2) where tearing is otherwise most likely to occur. The extension of the margins of the

panels

24 and 32 provides the desired reinforcing at these points of stress due to weight in lifting the carrier. The carrier is fabricated in collapsed condition as shown in FIG. 6 and delivered to the user where it is opened up into tubular form, as shown in FIG. 7, for loading through an open side or end. Thereafter, the carrier is loaded and the end panels are closed and locked by folding the panels into closed position and manipulating the locking and latching panels 64, 64' so as to engage the primary latching or locking members 72, 72' and the secondary latching members or

tabs

68, 68 in the openings 74, 74' provided in panels 44, 44'. Suitable equipment may be provided for closing and locking the end wall panels such as, for example, equipment employing the arrangement disclosed in Reissue US. Pat. No. 26,750, dated Jan. 6, 1970, for closing and locking bottom wall forming panels having similar locking and latching elements.

The cans may be dispensed by gravity rollout through an opening provided by tearing out the side and

end wall areas

76, 76' and 78, 78' as shown in FIG. 4. The

scores

84, 84 in the end wall panels stiffen the flap 92 which results from tearing out the

areas

76, 76' and 78, 78'.
