FIG. 6 is a perspective view of the carton of FIG. 5 when set up and ready for loading; and

FIG. 7 is a view similar to FIG. 6 but with parts cutaway to facilitate an understanding of the disposition of the various parts.

BEST MODE OF CARRYING OUT THE INVENTION

The blank as shown in FIG. 1 includes a side wall 1 which is foldably joined to end wall panels 2 and 3 along fold lines 4 and 5 respectively. A bottom panel 6 is foldably joined to side wall 1 along fold line 7 and a glue flap 8 is foldably joined to bottom panel 6 along fold line 9. A riser panel 10 is foldably joined to end panel 2 along fold line 12 and riser panel 11 is foldably joined to end wall panel 3 along fold line 13.

The other side of the blank is similar and includes side wall 14 to which end panels 15 and 16 are foldably joined along fold lines 17 and 18 respectively. A riser panel 21 is foldably joined to end panel 15 along fold line 23 and riser panel 22 is foldably joined to end panel 16 along fold line 24. Riser panels 11 and 22 are foldably joined along their top edges at fold line 25 and riser panels 10 and 21 are foldably joined along their top edges at fold line 26.

A hand gripping aperture 27 is formed in riser panel 11 and a hand gripping aperture 28 is formed in riser panel 22. In like fashion, a hand gripping aperture 29 is formed in riser panel 10 and a similar handle gripping aperture 30 is formed in riser panel 21. A cushioning flap 31 is associated with aperture 29 and cushioning flap 32 is associated with hand gripping aperture 30 in a manner well known in the art.

The strengthening structure formed according to this invention includes a collapsible interconnection between bottom panel 6 and end wall panel 2 and includes anchoring panel 33 which is foldably joined to bottom panel 6 along fold line 34 together with a first web panel 35 joined to anchoring panel 33 along interrupted fold line 36 and a second web panel 37 foldably joined to first web panel 35 along a fold line 38. An attachment flap 40 is foldably joined to second web panel 37 along fold line 39 and to end wall 2 along fold line 41. Cut line 12a is aligned with fold line 12. A reinforcing tab 33a forms an integral projection of anchoring panel 33 and is struck from the first web panel 35. As is obvious particularly from FIG. 1 attachment flap 40 is of triangular configuration.

The reinforcing structure at the other side of the blank includes anchoring panel 42 foldably joined to bottom panel 19 along fold line 43 together with first web panel 44 foldably joined to anchoring panel 42 along interrupted fold line 45 together with a second web panel 50 foldably joined to first web panel 44 along fold line 51. A triangular attachment flap 52 is foldably joined along fold line 53 to an edge of second web panel 50 and is foldably joined to end wall 15 along fold line 54. Cut line 23a is aligned with fold line 23. A reinforcing tab 42a forms an integral projection of anchoring panel 42 and is struck from the first web panel 44.

In order to manipulate the blank of FIG. 1 into a completed carrier, an application of glue is made to anchoring panels 33 and 42 and to reinforcing tabs 33a and 42a as shown by stippling in FIG. 1. Thereafter end panels 2 and 15 together with riser panels 10 and 21 and the reinforcement structure associated with panels 2 and 15 are all elevated and folded along fold lines 34, 4, 17 and 43. After this folding operation the blank appears as shown in FIG. 2. This operation causes anchoring panel 33 and reinforcing tab 33a to become adhered to bottom panel 6 and also causes anchoring panel 42 and reinforcing tab 42a to become adhered to bottom panel 19. This relationship of parts insure that anchoring panels 33 and 43 and reinforcing tabs 33a and 42a are rigidly secured to bottom panel 6 and 19.

An application of glue is then made to riser panels 11 and 22 as indicated by stippling in FIG. 2. Thereafter riser panels 11 and 22 are elevated and folded into contact with riser panels 10 and 21 the fold being along fold lines 13 and 24 and the blank then appears as shown in FIG. 3.

An application of glue is then made to riser panels 11 and 22 as indicated by stippling in FIG. 3 and to an edge of bottom panel 19 as indicated by stippling in FIG. 2. Riser panel 22 and side wall 15 and associated structure are folded upwardly and to the left along fold line 25 and the blank then appears as shown in FIG. 4. Of course this operation secures the riser panels 11 and 22 together in face contacting relation.

Glue flap 8 is folded to the right along fold line 9 to cause the glue flap 8 to become adhered to an edge of bottom wall panel 19 and the carrier then appears in complete collapsed form as shown in FIG. 5.

When set up and ready for loading the carrier appears as shown in FIG. 6. FIG. 7 simply shows areas broken away so as to afford a view of the inside of the bottom of the carrier.

When fully assembled and set up, the notches 10a and 21a coincide with each other in flat face contacting relation and engage the notch 9a to aid in maintaining a stable set up condition for the carrier.

In order to set the carrier up from the collapsed condition shown in FIG. 5 and as is well known external forces are applied t the complete collapsed carrier so as to force the parts to occupy the position depicted in FIG. 6. Toward this end, the attachment flaps such as 40 and 52 yield by folding inwardly along fold lines 41 and 54 in order to accommodate an easy interlocking action between the locking hooks 10a, 21a which are in engagement with the notch 9a. The slits 12a and 23a allow the notched hook 10a, 21a to pass therebetween.

During a set up operation, the web panels 35 and 37 are folded upwardly along fold lines 38 and 51 and the attachment flaps are folded inwardly into the bevelled arrangement shown in FIG. 7 and thus allow the hooks 10a, 21a to move into engagement with the notch 9a. The fixed relationship between anchoring panels 33 and 42 and their associated reinforcing tabs 33a and 42a insures that fold lines 36 and 45 are fixed in relation to the bottom panels 6 and 19. After engagement of the hooks 10a, 21a with notch 9a, the hooks 10a, 21a and the end wall panels 2 and 15 move inwardly and the attachment flaps may retain the bevelled positions shown in FIG. 7. Loading of bottles forces the web panels 35, 37 and 44 and 50 into coplanar relation and the attachment flaps assume coplanar positions with the end wall panels 2 and 15. The coplanar positions of web panels 35, 37, 44 and 50 greatly reinforces and strengthens the bottom wall.

Basket style article carriers for packaging two large bottles are subjected to high stress when a purchaser simply removes one bottle and leaves the other bottle in the carrier. By this invention the carrier is provided with a rigid mechanically strong bottom structure which includes the coplanar web panels 35, 37 and 44, 50 to prevent failure of the carrier when only one bottle is left in the carrier. Also by use of the novel attachment flap the carrier is arranged to facilitate set up operations.
