Weiss, Bergenfield, N.J., assignor to Continental Can Company, Inc., New York, N.Y., a corporation of New York Filed Oct. 28, 1964, Ser. No. 406,932 16 Claims. (Cl. 206-65) This invention relates to a novel wraparound carton and blank, and in particular, to a novel wraparound carton having a top panel provided with a plurality of transversely and longitudinally spaced and aligned cutouts for receiving portions of articles packaged in the carton, and a tab associated with each cutout for protecting the article portions against damage during the storage and shipment of the packaged cartons.

An object of'this invention is to provide a novel carton of the type having a top panel and a pair of side panels,

the top panel including a central panel portion and a pair of side panel portions joining the central panel portion to the side panels, a plurality of cutouts formed in each of the side panel portions for interlockingly receiving and retaining shoulder portions of containers packaged in the carton to prevent the inadvertent or accidental removal of the containers from the carton, and a tab portion associated with each of the cutouts forming an integral extension of the side panels for protecting the shoulder portions of the containers projecting through the cutouts against damage.

A further object of this invention is to provide a novel carton of the type described in which each of the cutouts is of a generally Oshaped configuration opening away from the central panel portion of the top panel, and the tabs forming integral extensions of the side panels are formed from material of the side panel portions.

A further object of this invention is to provide a novel carton of the type immediately set out above, and in addition, to provide a container neck-receiving opening in the central panel portion of the top panel between transversely opposed ones of the cutouts in the side panel portions for receiving the necks of containers packaged in the carton.

Another object of this invention is to provide a novel wraparound carrier or carton blank including a plurality of transverse weakening lines separating the blank into at least an integral top panel and a pair of side panels, the top panel being formed of a central panel portion and opposite side panel portions joining the central panel portion to adjacent side panels, a plurality of longitudinally aligned cutouts formed at least partially in each of the side panel portions, the cutouts being generally of a C- shaped configuration, transversely aligned ones of the cutouts being oppositely directed from a longitudinal center line of the top panel, each of the cutouts being partially defined by an edge of a tab in each side panel portion directed toward the central panel portion, and the central panel portion having a plurality of container neckreceiving openings disposed in transversely spaced relationship along the center line of the top panel.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawings.

In the drawings:

FIGURE 1 is a top perspective view of a wraparound carton or carrier constructed in accordance with this invention, and illustrates cutouts in a top panel retaining shoulder portions of a container packaged in the carrier and a tab associated with each cutout for protecting the exposed shoulder portions.

FIGURE 2 is an enlarged fragmentary top plan view of the wraparound carrier of FIGURE 1, and more clearly illustrates the relationship between the container shoulder portions, the cutouts and the tabs.

FIGURE 3 is a fragmentary longitudinal sectional view taken along line 33 of FIGURE 2, and illustrates adjacent containers retained in the carrier in longitudinally spaced relationship.

FIGURE 4 is a transverse sectional view taken along line 4-4 of FIGURE 3, and illustrates a pair of the carriers packaged in a shipping container with the tabs preventing contact between the shoulder portions of adjacent containers and between the containers and the shipping carton.

FIGURE 5 is a top plan view of the exterior of a substantially rectangular blank from which the wraparound carrier of FIGURE 1 is constructed, and illustrates the relationshi of the shoulder portion receiving cutouts, the tabs and the container neck-receiving openings of the top panel.

A novel wrap-around carrier or carton constructed in accordance with this invention is best illustrated in FIG- URES 1 through 3 of the drawings, and is generally designated by the reference numeral 10. The carrier or carton is constructed from a blank 11 of FIGURE 5. The carrier 10 will be best understood by first describing the carrier blank 11 of FIGURE 5 to which attention is directed.

The wraparound carrier or carton blank 11 of FIG- URE 5 comprises a substantially rectangular blank of paperstock material defined by a pair of

longitudinal edges

12, 13, a straight first transverse edge 14 and an irregular second transverse edge 15.

An inner or first closure panel 16 of the blank 11 is set off by the first transverse edge 14, a first transverse weakening line 17, and portions of the

longitudinal edges

12 and 13. The weakening line 17 is formed of alternating fold lines 18 and partial score lines 20. A plurality of equally transversely spaced generally trapezoidal latch-receiving openings 21 are formed in the inner closure panel 16 for a purpose to be described more fully hereafter. Three such latch-receiving openings 21 are formed in the inner closure panel 16 to each side of a out line 22 formed along the longitudinal center line of the blank 11 between the transverse edge 14 and a centermost one of the fold lines 18 of the weakenw ing line 17.

A first side panel 23 of the carrier blank 11 is set oflf between the first weakening line 17, a second weakening line 24, and portions of the

longitudinal edges

12 and 13.

A top panel 25 of the carrier blank 11 is set 011? between the second weakening line 24, a third weakening line 26 and portions of the

longitudinal edges

12, 13.

A second side panel 27 of the blank 11 is defined by portions of the pair of

longitudinal edges

12, 13, the third transverse weakening line 26 and a fourth transverse weakening line 28.

A second or outer closure panel 30 of the blank 11 is defined by portions of the

longitudinal fold lines

12, 13, the fourth transverse fold line 28, and the irregular transverse edge 15.

A plurality of transversely spaced latching members 31 form integral portions of the outer closure panel 30 of the blank 11, and each latching member 31 is in longitudinal alignment with an associated one of the latchreceiving openings 21 of the inner closure panel 16. The latching members 31 are identical and each includes a latching tongue 32 having a pair of oppositely directed, short,

transverse slits

33, 34 and an oppositely directed locking tab 35. The locking tabs 35 are formed by generally shallow, inverted C-shaped slits, 36 disposed in transverse spaced relationship along a transverse weakening line 37 which may, for example, be in the form of a plurality of short partially severed fold lines (individually unnumbered). Each locking tongue 32 and latching tab 35 is receivable in a respective latch-receiving opening 21 of the inner closure panel 16 in the manner clearly illustrated in FIGURE 1 of the drawings.

The outer closure panel 30 is provided with three locking members 31 to each side of a short longitudinal cut line 38 in alignment with the cut line 22 of the inner closure panel 16. The cut line 38 extends between the irregular transverse edge and a centermost fold line 40 which, in addition to similar such fold lines and alternating score lines 41 define the fourth transverse weakening line 28.

A plurality of identical transversely spaced generally crescent-shaped openings 42 are formed in the

side panels

23, 27. A projection 43 adjacent each of the severance lines of the first transverse weakening line 17 partially defines an associated one of the crescent-shaped openings 42 and functions to provide a bottom supporting ledge for articles A packaged in the carrier 10, as is clearly illustrated in FIGURES 1 and 4 of the drawings. A similar projection 44 partially defining the crescent shaped openings 42 of the closure panel provides a similar supporting ledge for each of the articles A.

A transverse weakening line 45 in the form of a fold line between the transverse weakening lines 17 and 24 is interrupted along its length by a plurality of arcuate cut lines 46 adjacent each of the crescent-shaped openings 42 of the side panel 23. Each of the cut lines 46 set ofi an identical bottle-embracing tab 47. A similar fold line 48 in the second side panel 27 is spaced from and parallel to the fourth transverse weakening line 28-, and is interrupted by a plurality of arcuate cut lines 50. Each of the arcuate cut lines 50 define bottle-embracing tabs 51 (FIGURES 1 and 4).

The top panel 25 of the blank 11 is divided into three top panel portions 52-54 by a pair of transverse weakening

lines

55, 56. The pair of transverse weakening

lines

55, 56 are fold lines which are preferably partially severed as at 57, 58, respectively. The transverse weakening line 55 and the second transverse weakening line 24 define one side panel portion 54 joining the central panel portion 53 of the top panel 25 to the side panel 23 while the transverse weakening line 56 and the third transverse weakening line 26 defined an opposite side panel portion joining the central portion 53 of the top panel 25 to the second side panel 27 A second pair of transverse weakening lines in the form of interrupted fold lines 60, 61 are formed in the top panel 25. The weakening line 60 of the second pair of weakening lines 60, 61 is between and parallel to the weakening lines 24, 25 while the weakening line 61 of the second pair of weakening lines 60, 61 is between and parallel to the weakening

lines

26 and 56.

A plurality of longitudinally and transversely spaced and aligned generally crescent or C-shaped cutouts 62 are formed in the

side panel portions

52, 54 of the top panel 25. Each of the crescent-shaped cutouts 62 is defined by an arcuate edge 63 projecting slightly into the central portion 53 of the top panel 25 at 64. Each cres cent-shaped cutout 62 is further defined by an arcuate edge 66 of an integral portion of each of the

side panel portions

52, 54 projecting toward the central portion 53 of the top panel 25. The crescent-shaped cutouts 62 define openings through which project shoulders S of the articles A (FIGURES 1 and 4) while the arcuate edges 63 retain and maintain the articles A in longitudinally spaced relationship. The projecting integral portions 65 partially overlie and protect the shoulders S of the articles A (FIGURES 1 and 4).

The central portion 53 of the top panel 25 is provided with a plurality of circular container neck-receiving openings 67. The openings 67 are disposed in longitudinal alignment with the crescent-shaped cutouts 62 of the blank 11, and are in longitudinal spaced relationship along the center line of the top panel 25. The openings 67 receive the necks N of the articles A packaged in the carton 10 as is clearly shown in FIGURES 1, 3 and 4 of the drawings.

The side panel 27 is further provided with a fingerreceiving opening 68 whose axis lies on an imaginary line connecting the

cut lines

22 and 38 of the

respective closure panels

16 and 30. An identical tear strip 70 at each transverse side of the finger-receiving opening 68 is formed in the side panel 27 by a pair of parallel partial lines of severance 71.

The wraparound carton or carrier 10 is formed by first aligning a single row of the articles A on a supporting surface, which may, for example, be a conveyor belt or similar article-transporting mechanism of a conventional wrapping mechanism (not shown). The articles A are liquid-containing glass bottles of a relatively fragile nature. Adjacent articles A in the row are spaced apart a distance equal to the distance between the axes of the plurality of openings 67 in the top panel 25 of the blank 11.

When the bottles are thus positioned, one of the plurality of carrier blanks supported above the row of articles A-in a conventional manner is lowered until the necks N of the articles A project through the associated neckreceiving openings 67 When the articles A are thus positioned, the

closure panels

16 and 30 are urged downwardly simultaneously to wrap the carrier blank 11 about the articles A. As the

closure panels

16 and 30 are drawn downwardly the shoulder portions S of each article A are received in the crescent-shaped cutouts 62 and confined therein by the arcuate edges 63, as is best illustrated in FIGURE 2 and FIGURE 3 of the drawings. Because of the interrupted nature of the second pair of fold lines 60, 61 of the top panel 25, the tabs 65 do not fold to the generally angular relationship of the

side panel portions

52, 54 relative to the central portion 53 of the top panel 25 and the

side panels

23, 27. Rather, the tabs 65 remain substantially in the plane of the side panels 23, 27 (FIGURES 1, 2 and 3), and overlie major portions of the exposed shoulders S to protect the same against breakage, marring or other damage during storage and/ or shipment.

The inner closure panel 16 and the outer closure panel 30 are then secured together by the interlocking of the latching members 31 with the latch-receiving openings 21. This interlocking or latching is clearly illustrated in FIGURES 1 and 4 of the drawings, and a further description thereof is considered unnecessary for a complete understanding of this invention.

Attention is now directed to FIGURE 4 of the drawings in which two of the packaged cartons 10 are shown housed in a shipping container generally referred to by the reference numeral 80. The shipping container is of a conventional construction and includes a bottom wall 81, a pair of upstanding

parallel side walls

82, 83 opposed end walls 84 (only one of which is illustrated) and a top wall 85 formed of a plurality of overlapped and secured flaps (individually unnumbered). During the shipment of the packaged carton 10 in the shipping container 80 of FIG- URE 4, the shoulders S of adjacent ones of the articles A are protected by the tabs 65, it being noted that a double thickness of material is provided between these adjacent shoulders. Likewise, the outermost shoulders of the articles A are spaced from the

side walls

82, 83 of the container 80 by the tabs 65 adjacent thereto. In this manner, each of the shoulders of the articles are protected from a shoulder of an adjacent article and from the exterior walls of the shipping container.

From the foregoing, it will be seen that novel and advantageous provision has been made for carrying out the desired end. However, attention is directed to the fact that other variations may be made in the example wraparound carrier and blank disclosed herein without departing from the spirit and scope of this invention as defined in the appended claims.
