HEAVY DUTY ARTICLE CARRIER Development of the so-called screw-on resealable bottle cap and the attendant trend toward larger and larger bottles has resulted in the imposition of substantial weight which must be supported and carried by the handle and partition structure of basket style carriers. Conventional basket carriers are efficient and sufficiently sturdy to accommodate small and medium sized bottles but simply are not sufficiently strong to accommodate large bottles such as 32, 48 and 64 02. bottles which are in common use today.

According to this invention a basket style article carrier having bottom, side and end walls together with a medial longitudinal partition and handle structure is reinforced in a transverse direction by a conventional partition strip and, in addition, a supplementary transverse partition strut is foldably joined to each partition strip and is secured at each side edge thereof by glue flaps which affix the strut to both the side walls and to the longitudinal partition and handle structure. According to another facet of the invention, a basket style carrier is reinforced in the longitudinal direction by means of a longitudinal panel which is formed integrally with an inner handle panel and which is foldably joined to the end wall at one end of the carrier and which is secured in overlapping relation with medial inwardly extending riser panels which are foldably joined to the end wall at the other end of the carrier. The carrier is formed from a single unitary blank.

For a better understanding of the invention reference may be had to the following detailed description taken in conjunction with the accompanying drawings in which FIG. 1 is a perspective view ofa set-up carrier formed according to this invention;

FIG. 2 is a plan view of the blank from which the carrier shown in FIG. 1 is formed and in which FIGS. 3-7 inclusive represent sequential gluing and folding operations through which the blank of FIG. 2 is manipulated in order to form the completed and collapsed carrier as shown in FIG. 7.

In the drawings the numeral 1 designates the bottom wall which is foldably joined along fold line 2 to side wall 3 and which is provided with a medial fold line 4. End wall panel 5 is foldably joined along fold line 6 to one end of side wall 3 while end wall panel 7 is foldably joined along fold line 8 to the opposite end of side wall 3. A riser panel 9 is foldably joined along fold line 10 to the medial edge of end wall panel 5 and handle panel 11 having hand gripping aperture 12 formed therein is provided with a portion 13 having a locking notch 14 therein. Panel 11,13 is foldably joind to end wall panel 7 along fold line 15.

Outer handle panel 16 is foldably joined to riser panel 9 along fold line 10 and is provided with a hand gripping aperture 17. A transverse partition strip 18 is foldably joined to outer handle panel 16 along vertical fold line 19 and at its outer end partition strip 18 is foldably joined to side wall 3 along vertical fold line 20.

According to one feature of this invention, transverse partition strut 21 is foldably joined to transverse partition strip 18 along downwardly inclined fold line 22. Glue flap 23 is foldably joined to transverse partition strut 21 along fold line 24. Glue flap 23 is also foldably joined to side wall 3 along a fold line 25 which as is apparent in FIG. 2 is disposed in alignment with fold line 22. At the opposite side edge of transverse partition strut 21 a glue flap 26 is foldably joined to partition strut 21 along fold line 27.

The other side of the blank is similar to that already described and includes an outer handle panel 28 which is foldably joined to outer handle panel 16 along fold line 29 and is provided with a hand gripping aperture 30. A riser panel 31 is foldably joined to outer handle panel 28 along fold line 32 and to end wall panel 33 along fold line 32. End wall panel 33 is foldably joined to side wall 34 along fold line 35 and a transverse partition strip 36 is foldably joined to outer handle panel 28 along vertical fold line 37 and to side wall 34 along vertical fold line 38. End wall panel 39 is foldably joined along fold line 40 to an end edge of side wall 34 and handle panel 41 having hand gripping aperture 42 formed therein is foldably joined to end wall panel 39 along fold line 43. Inner handle panel 41 is also foldably joined to inner handle panel 12 along aligned

fold lines

44 and 45 which for convenience are separated by slit 46. A locking notch 47 is formed in the lower portion of downwardly extending medial longitudinal part 48 of handle panel 41. A glue flap 49 is foldably joined to side wall 34 along a fold line 50.

In accordance with one facet of this invention, a transverse partition strut 51 is foldably joined along downwardly inclined fold line 52 to the outer portion of transverse partition strip 36. A glue flap 53 is foldably joined along fold line 54 to the inner side edge of partition strut 51 and a glue flap 55 is foldably joined to transverse partition strut 51 along a fold line 56 and to side wall 34 along a fold line 57 which is disposed in substantial alignment with fold line 52.

In order to form the carrier as shown in FIGS. 1 and 7 from the blank depicted in FIG. 2, an application of glue is first made to the

transverse partition strips

18 and 36, to the

glue flaps

23 and 55, and to the center portions of

side walls

3 and 34 as shown by stippling in FIG. 2. Thereafter the transverse partition strut 21 and its

glue flaps

23 and 26 are elevated and folded upwardly and toward the left along

fold lines

22 and 24. This operation causes the glue flap 23 to adhere to the side wall 3 and causes those portions of the transverse partition strut 21 which are adjacent fold line 22 to adhere to the transverse partition strip 18. Simultaneously transverse partition strut 51 and its

glue flaps

53 and 55 are elevated and folded downwardly and generally toward the left to cause the glue flap 55 to adhere to the center portion of side wall 34 and also to cause those portions of transverse partition strut 51 which are adjacent to fold line 52 to adhere to partition strip 36. Upon completion of these two folding operations, the blank appears as shown in FIG. 3.

An application of glue is then made to the inner surfaces of

outer handle panels

16 and 28 and to the longitudinal downwardly extending part 48 of inner handle panel 41 as indicated by stippling in FIG. 3. Following this application of glue,

end wall panels

7 and 39 and handle panels 11 and 41 are elevated and folded toward the left along

fold lines

8 and 40. This operation causes the inner handle panels 11 and 41 to adhere to the inner surfaces of

outer handle panels

16 and 28 respectively and causes the aligned but separated

fold lines

44 and 45 between inner handle panels 11 and 41 to overlie the fold line 29. This folding operation also causes the longitudinal portion 48 of handle panel 41 to adhere to glue flap 53. The blank then appears as shown in FIG. 4.

An application of glue is then made to portions of

riser panels

9 and 31 as indicated by stippling in FIG. 4. Thereafter the

riser panels

9 and 31 are elevated and folded toward the right along the

fold lines

10 and 32 respectively to occupy the positions depicted in FIG. 5. Of course this folding operation causes the upper ends of

riser panels

9 and 31 adjacent fold line 29 to adhere to the inner surfaces of

outer handle panels

16 and 28 and to the left hand end portions of inner handle panels 11 and 41.

With the blank in the form shown in FIG. 5, the bottom wall 1 is collapsed along its medial fold line 4 by simply folding the upper portion of bottom wall 1 forwardly and downwardly to cause the bottom panel 1 to appear as shown in FIG. 6.

The blank as shown in FIG. 6 is then given an application of glue as indicated by stippling in that figure. Specifically, glue is applied to

riser panels

9 and 31 to the inner surfaces of handle panels 11 and 41, to the downwardly extending part 13 of panel 11 and to a por tion of longitudinal panel 48 as well as to the glue flap 49. A spot of glue is disposed on panel 48 as shown at 48a. With the blank glued as shown in FIG. 6, side wall 3 and all partsassociated therewith which are disposed above the fold line 29 and the

fold line

44,45 are elevated and folded forwardly to cause the blank to ap pear as shown in FIG. 7.

This operation causes the

riser panels

9 and 31 to adhere to each other and also causes the inner handle panel 11 to adhere to inner handle panel 41 while securing part 13 of panel 11 to longitudinal panel 48 and also adheres the glue flap 26 to longitudinal panel 48 while glue flap 49 is secured to the corresponding edge of bottom panel 1.

The final folding operation as is well known causes the locking notch 3 to fall into coincidence with locking notch 47. Thus in order to set up the carrier as shown in collapsed form in FIG. 7, it is simply necessary to hold end wall panels and 33 against movement toward the left by exerting a force along the

medial edges

10, 32 thereof and by simultaneously applying a force toward the left to the

end edges

8 and 40 of

side walls

3 and 34 respectively. This operation causes the

side walls

3 and 34 to move apart and causes the

end wall panels

5 and 33 to occupy the same plane.

End wall panels

7 and 39 also Swing into the same plane. When locking

notch

14,47 engages an end edge of bottom wall 1 the carrier is locked in set-up condition and appears as shown in FIG. 1.

From the above description it is apparent that the carrier is unusually sturdy and strong in a transverse direction due to the fact that on one side of the longitudinal partition and handle structure, a transverse partition strut 2lby virtue of its glue flaps 23 and 26 is securely affixed to the longitudinal panel 48 which forms a part of the longitudinal partition and handle structure and to the side wall 3. Similarly on the other side of the longitudinal handle and partition structure, the trans verse strut 51 is disposed. Glue flap 55 secures the strut 51 to side wall 34 and glue flap 53 secures the strut 51 along its other side edge to the longitudinal panel 48 so that both side walls and handle are effectively biased. Furthermore, the carrier is unusually strong in a longitudinal direction by virtue of the fact that the longitudinal panel 48 is secured in overlapping relationship with respect to the

riser panels

9 and 31 as is apparent from FIGS. 4 and 5. Thus by the invention, a basket style carrier is rendered sufficiently strong and sturdy to accommodate large primary packages such as bottles whose

contents weight

32, 48 and even 64 ounces.
