Detailed Description of the Preferred Embodiments

Referring to the drawings, and particularly to Figures 1 and 2 thereof, a bottle carrier "C" is formed from a single blank 10 of paperboard or other suitable foldable sheet material and is adapted to accommodate six bottles "B" (Figure 9) arranged in two rows of three bottles each. Of course, in other embodiments, the carrier may be formed from two or more blanks and may be adapted to hold a different number of bottles arranged in an alternative array structure, without departing from the scope of invention.
The article carrier comprises a plurality of panels hingedly connected together to form the opposed sides, ends and base. In this embodiment, the carrier comprises a first side wall panel 12 to the lower edge of which is hinged a main base panel 14. Base panel 14 is hinged to side wall panel 12 along fold line 16. To complete the base of the carrier, when the carrier is formed, the free edge of base panel 14 is secured to a base securing strip 18. This is done after the carrier is loaded with bottles. Base strip 18 is hinged to the lower edge of a second opposing side wall panel 20 of the carrier along a fold line 22.
One end of the carrier is provided by end panels 50 and 52 respectively. End panel 50 is hinged along fold line 54 to intermediate panel 56, which provides a bevelled corner panel between side panel 12 and end panel 50. Panel 56 is hinged to side panel 12 along fold line 58. A medial panel strip 60 may be provided which is hinged to the opposite end edge of end panel 50 along fold line 66.
Similarly, end panel 52 is hinged along fold line 68 to intermediate panel 70, which provides another bevelled corner panel of the carrier between side panel 20 and end panel 52. Panel 70 is hinged to side panel 20 along fold line 72. Along its opposite end edge panel 52 is hinged to the medial structure along fold line 76.
The opposite end of the carrier is provided by end panels 82 and 84 respectively. End panel 82 is hinged along fold line 86 to intermediate panel 88, which provides a bevelled corner panel between side panel 20 and end panel 82. Panel 88 is hinged to side panel 20 along fold line 90. Along its opposite edge, panel 82 is hinged along fold line 92 to an adjacent end panel 84. Similarly, end panel 84 is hinged along fold line 94 to intermediate panel 96, which provides a bevelled corner panel between side panel 12 and end panel 84. Panel 96 is hinged to side panel 12 along fold line 98.
In other embodiments, the intermediate panels 56, 70, 88, 96 are dispensed with so that the carrier is provided with substantially perpendicular corners.
The medial structure is provided by first medial panel 74 hinged to second medial panel 78 along fold line 80 and forms a part of the central internal structure of the carrier beneath the handle structure H. In one class of embodiments the construction of the medial panels 74 and 78 respectively, is as follows:
Medial panel 74 comprising an integral handle panel portion 74a to which is hinged a reinforcing handle panel 100 along fold line 102 which is folded into face to face relationship with panel portion 74a. From both these panels is struck hand aperture 104 adjacent the upper edge of the reinforced panel 74. In order to create partitions which, in part, define one row of individual cells of the carrier, a pair of transverse partition panels 81 and 83 are struck from and hinged to the main medial panel 74 along fold lines 87 and 91 respectively. The opposite ends of the transverse partition panels are joined to one another by a common anchoring panel 85 along fold line 89.
One or more securing flaps are provided and hingedly connected to first medial panel 74. In this embodiment two securing flaps 114 and 116 are hingedly connected to the outer end edge of main medial panel 74 at spaced locations along fold lines 118 and 120, respectively.
Second medial panel 78 is hinged to medial panel 74 along fold line 80 disposed between but longitudinally (of the blank) displaced from fold lines 118 and 120. By offsetting fold line 80, for example inwardly into first medial panel, enables the second medial panel to be reduced in width, thereby reducing the amount of paperboard required.
In order to create further partitions which, in part, define the other row of individual cells of the carrier, a pair of transverse partition panels 122, 124 are struck from and hinged to the secondary medial panel 78 along fold lines 126 and 128 respectively. The opposite ends of the transverse partition panels are joined to one another by a common anchoring panel 130 along fold line 132.
In one embodiment of the present invention, in order to prevent individual bottles from being removed from the carrier the bottles are restrained by cover panels, which can be detached after the full carrier has been purchased. The cover panels also help to keep the bottles dust free.
A handle structure H (Figure 9) is provided and includes an integral top panel 24 which covers the bottle receiving cells along one side of the handle structure H but includes a series of openings S₁, S₂, S₃ through which neck portions of bottles accommodated in those cells protrude. Top panel 24 is hinged to side wall panel 12 along a frangible score line 26 and is also integral with and hinged to a handle panel 28 along fold line 30. There may further comprise first and second handle reinforcing flaps 32 and 34 hingedly connected to handle panel 28 along score lines 35 and 36 respectively. Thus, in use, the top panel 24 can be torn away along the frangible score line 26 and detached, at least partially, to allow bottles in the underlying cells to be taken from the carrier. Handle panel 28 may include handle openings HH that is reinforced by hinged handle flaps 32 and 34 with registering openings.
There may further comprise a second integral top panel 38 which covers the bottle receiving cells on the opposite side of the handle structure H and includes a series of openings S₄, S₅, S₆ through which neck portions of bottles accommodated in those cells protrude. Top panel 38 is hinged to side wall panel 20 along a frangible score line 40 and is also integral with and hinged to a second handle panel 42 along score line 44. Thus, in use, the top panel 38 can be torn away along the frangible score line 40 and at least partially detached to allow bottles in the underlying cells to be taken from the carrier. Handle panel 42 includes handle openings HH and is reinforced by a handle flap 46 hinged along fold line 48. Handle openings in handle flap 46 are put into registry with handle openings HH when handle structure H is formed.
In order to form the completed carrier in flat collapsed condition from the blank, a series of sequential folding and gluing operations are required and reference is made to Figures 2, 3, 4, 5, 6 and 7. Although some of these operations are known to those skilled in the art, in this particular case, first the handle reinforcing panel 46 is folded about fold line 48 and secured in face to face relationship with handle panel 42. Handle structure reinforcing panels 32 and 34 likewise are folded and secured in face to face relationship with handle panel 28.
Likewise reinforcing panel 100 is folded about fold line 102 and secured in face to face relationship with the upper panel portion 74a of main medial panel 74 so that the blank is in a part folded condition shown in Figure 3.
Referring to Figure 4, second medial panel 78 is folded inwardly about fold line 80 into face to face relationship with medial panel 74 so as to reveal securing flaps 114, 116. The securing flaps are then secured to the end wall panel 82, 84 by glue or other suitable means known in the art. In this embodiment, glue is applied to areas G comprising anchor panel 130 and securing flaps 114 and 116 respectively.
Medial panel structure 74, 78 is folded inwardly about fold line 68 whereby the common anchoring panel 130 is adhered to side wall panel 20 and anchoring tabs 114, 116 are secured in face to face relationship with end wall panel 84. Similarly, end wall structure 50, 60 is folded inwardly about fold line 54 into face to face relationship with side wall panel 28. The part assembled blank is in the form shown in Figure 5.
The opposing ends of the blank are secured together. Referring to Figure 6, glue is then applied to areas G comprising the upper parts of reinforcing panels 32, 34; the medial panel strip 60 and the anchoring panel 130. Thereafter, as shown in Figure 7, the partially formed carrier is folded about the now central fold line 92 to bring those parts on either side of the central fold line 92 into face to face relationship whereby anchor panel 130 is adhered to side wall panel 12; handle reinforcing panels 46, 32, 34 are adhered together and medial panel strip 60 is adhered to the exposed face of end wall panel 52. The carrier is then in a flat collapsed form from which it can be erected for loading.
Loading is accomplished by relative vertical movement between bottles and carrier during common forward feed movement, well known in the art, by which the carrier is erected by separating the opposed sides and ends, as shown in Figure 8 and the bottles enter their respective cells and through apertures S₁, S₂, S₃ S₄, S₅ and S₆ through the open bottom of the carrier. Thereafter, the bottom panel 14 is folded upwards to close the lower ends of the bottle cells and the free edge of bottom panel 14 is secured in overlapping relationship with the free edge of securing strip 18 to form the base of the carrier and hence the loaded carrier is complete, as illustrated in Figure 9.
In order to gain access to the contents of the carrier C, the top panels 24 and 38 may be removed by tearing along the frangible fold lines 26 and 40 in order to expose the bottles. However, this action does not destroy the overall integrity of the carrier so that empty bottles can be returned in the carrier to a point of sale. Optionally, the upper part 74a of the medial partition structure serves as a handle.
The basket type carrier shown with reference to Figures 10 to 18 is of similar construction to the carrier described above, except in the following substantive respects, and like parts thereof are designated like reference numerals with the addition of the prefix '2'(or as the case may be '3' instead of the first numeral '1') in Figures 1 to 9. Only the differences will be described in any greater detail.
Base panels 214 and 218 incorporate known locking means and because of the absence of upper panels 24, 38 (of the previous embodiment) the carrier of Figures 10 to 18 is loaded from above after the base panels 214 and 218 have been overlapped and locked together. The only other significant differences apart from dimensional changes are that the handle structure has no reinforcing panels such as panels 32, 34 and 46 of the previous embodiment and there are no top cover panels (such as panels 24, 38) to close the top of the carrier.
The medial partition structure is similar to the first embodiment and is provided with medial panel 274 comprising an integral handle panel portion 246 to which is hinged a reinforcing handle panel 242 along fold line 276 which is folded into face to face relationship with panel portion 246. From both these panels is struck hand aperture adjacent the upper edge of the reinforced panel 274. In order to create partitions which, in part, define one row of individual cells of the carrier, a pair of transverse partition panels 281 and 283 are struck from and hinged to the main medial panel 274 along fold lines 287 and 291 respectively. The opposite ends of the transverse partition panels are joined to one another by a common anchoring panel 285 along fold line 289.
One or more securing flaps are provided and hingedly connected to first medial panel 274. In this embodiment two securing flaps 314 and 316 are hingedly connected to the outer end edge of main medial panel 274 at spaced locations along fold lines 318 and 320, respectively.
Second medial panel 278 is hinged to medial panel 274 along fold line 280 disposed between but longitudinally (of the blank) displaced from fold lines 318 and 320. By offsetting fold line 280, for example inwardly into first medial panel, enables the second medial panel to be reduced in width, thereby reducing the amount of paperboard required.
In order to create further partitions which, in part, define the other row of individual cells of the carrier, a pair of transverse partition panels 322, 324 are struck from and hinged to the secondary medial panel 278 along fold lines 326 and 328 respectively. The opposite ends of the transverse partition panels are joined to one another by a common anchoring panel 330 along fold line 332.
The carrier is constructed in like manner to the first embodiment, whereby the second medial panel 278 is folded inwardly and is secured to the first medial panel 274 by glue or other suitable means known in the art as shown in Figures 11 and 12 to reveal securing flaps 314 and 316.
Thereafter, medial partition structure is folded inwardly along fold line 276 to be placed in face contacting arrangement with side wall panel 220 and handle panel 242 and is secured thereto, in like manner to the first embodiment and shown in Figure 13.
Thereafter, the sides and ends of the article carrier are constructed whereby securing flaps 314, 316 are secured to end wall panel 282 shown in Figures 14 and 15. End wall panel 252 is secured to end wall panel 251 as shown in Figure 16, so that the carrier is in a flat collapsed condition, ready to be supplied to an end user.
To complete construction of the carrier shown in Figures 17 and 18, the sides and ends are separated, articles loaded into the carrier and the base wall is formed.
The present invention and its preferred embodiment relates to an arrangement for providing a more economical basket carrier. However, it is anticipated that the invention can be applied to a variety of carriers and is not limited to those of the basket style hereinbefore described and could be used for numerous applications for example a wrapamund carton or fully enclosed carton.
It will be recognised that as used herein, directional references such as "top", "base", "end", "side", "inner", "outer", "upper" and "lower" do not limit the respective panels to such orientation, but merely serve to distinguish these panels from one another . Any reference to hinged connection should not be construed as necessarily referring to a single fold line only: indeed it is envisaged that hinged connection can be formed from one or more of the following, a score line, a frangible line or a fold line, without departing from the scope of invention.
It should be understood that various changes may be made within the scope of the present invention, for example, the size and shape of the panels and apertures may be adjusted to accommodate articles of differing size or shape, alternative top and base closure structures may be used. The carton may accommodate more than one article in different arrays.
