Wood, Joneshoro, Ga., assignor to The Mead Corporation, a corporation of Ohio Filed June 29, 1967, Ser. No. 649,890 6 Claims. (Cl. 220-113) ABSTRACT OF THE DISCLOSURE An article carrier having a medial handle partition, end panels foldably joined to the end edges of said handle partition, and side walls foldably joined along their end edges to the side edges of the end panels provided with a composite bottom panel. The composite bottom panel includes a main bottom panel foldably joined to the bottom edge of one of the side walls and a corner portion of the main bottom panel is cut away. A complementary bottom panel is foldably joined along a side edge thereof to a side edge of the main bottom panel which is adjacent to the cutaway portion so that when the complementary panel is folded into flat face contacting relation with the main panel, a composite structure results. This arrangement affords a sturdy bottom structure and also accommodates end-to-end nesting of adjacent carriers in reversed aligned relation to each other, the cutaway portion of one main bottom panel being disposed to receive a substantial projecting portion of the main bottom panel of a reversed adjacent carrier.

Substantial economy of material is effected by end-toend nesting of the bottom panel of one blank with an aligned reversed adjacent blank of an article carrier, nesting being made possible by constructing the bottom of a main panel having a cutaway corner portion and a complementary panel foldably joined to the main bottom panel along a side edge thereof and adjacent the cutaway portion, the complementary portion being folded over in flat face contacting relation with the main bottom panel. The invention is particularly beneficial if the carrier blanks are cut from sheet material,

In the drawings, FIG. 1 is a perspective view of a set-up carrier constructed according to the invention; FIG. 2 is a plan view of a blank from which the carrier of FIG. 1 is constructed; FIGS. 3, 4 and 5 represent folding and gluing operations through which the blank of FIG. 2 is manipulated to form the complete collapsed carrier depicted in FIG. 5; and FIG. 6 is a plan view of one blank such as is shown in FIG. 2 shown in solid lines together with a second adjacent nested blank shown partially in dotted lines.

In the drawings the numeral 1 designates a side wall of the carrier and the numeral 2 designates a glue flap which is foldably joined to the bottom edge of side wall 1 along fold line 3. End panel 4 is foldably joined to one end of side wall 1 along a fold line 5 while end panel 6 is foldably joined to the other end of side wall 1 along fold line 7. Riser panel 8 is foldably joined to end panel 4 along fold line 9 while riser panel 10 is foldably joined to end panel 6 along fold line 11.

The medial handle partition for the carrier includes the riser panels as well as

handle panels

12, 13, 14 and 15. Handle panel 12 is foldably joined to riser panel 8 along fold line 9 to handle panel 13 along medial fold line 16. Handle panel 14 is foldably joined to riser panel 10 along fold line 11 and to handle panel 15 along medial fold line 17. Conventional hand gripping apertures 18, 19, and 21 are formed in handle panels 12-15 respectively. As shown in the drawings, aperture 19 defines a flap which is foldably joined along the fold line 22 to the handle panel 13.

Partition structure on the side of the carrier adjacent side wall 1 is defined by the high center cell 1A and includes a partition strip 23 which is foldably joined along fold line 24 to an edge of portion 1A and along fold line 25 to the handle panel 12. Likewise partition strip 26 is foldably joined along fold line 27 to the high center cell portion 1A and along fold line 28 to the handle panel 14.

On the other side of the carrier, a riser panel 30 is foldably joined to handle panel 13 along a fold line 31 and a similar riser panel 32 is foldably joined to handle panel 15 along fold line 33. End panel 34 is foldably joined to riser panel 30 along fold line 31 While end panel 35 is foldably joined to riser panel 32 along fold line 33. Side wall 36 is foldably joined to end panel 34 along fold line 37 and to end panel 35 along fold line 38. Partition strip 39 is foldably joined to handle panel 13 along fold line 40 and to high center cell portion 36A along fold line 41. Likewise partition strip 42 is foldably joined to handle panel 15 along fold line 43 and to the high center cell section 36A along fold line 44.

Notches

45, 46, 47 and 48 are formed in the

riser panels

8, 10, 30 and 32 and cooperate with notches formed medially at the ends of the bottom panel in known manner.

The parts of the carrier described hereinabove are conventional.

In accordance with this invention, the bottom panel Which is foldably joined to the bottom edge 49 of side wall 36 is a composite panel comprising a main panel 50 and a complementary panel 51 which is foldably joined to main panel 50 along the side edge 52 thereof. A medial fold line 53 is formed in complementary panel 51 and a medial fold line 54 is formed in main panel 50. Locking

notches

55 and 56 are formed in

panels

51 and 50 respectively.

As is clearly shown in FIG. 6 main bottom panel 50 of the blank shown in dotted lines is nested Within the cutaway corner portion of the main panel 50 of the carton shown in solid lines and by the invention it is possible to nest one blank in aligned reversed end-to-end relation with an adjacent blank and by this means substantially to eliminate waste.

In order to form a composite bottom from the main panel 50 and the complementary panel 51, an application of glue is made to main panel 50 as indicated by stippling in FIG. 2 and thereafter the complementary panel 51 is folded upwardly and toward the right along the fold line 52 to occupy the position depicted, for example, in FIG. 3.

In accordance with a feature of the invention, the angle between fold line 52 and fold line 49 is slightly greater than Thus when panel 51 is folded into the position shown in FIG. 3, the right hand end of medial fold line 53 as shown for example in FIG. 3 is slightly below the left hand end of the medial fold line 54. Since complementary panel 51 is disposed on the inside of main panel 50 and since

panels

50 and 51 subsequently are folded along the

medial fold lines

53, 54 by lifting and folding forwardly the lower portions of the composite bottom panel, the complementary panel 51 is positively captured in the region adjacent the left hand end of fold line- 54.

According to another facet of the invention, a small cutaway notch 57 is formed at the end of medial fold line 53 which cutaway area is disposed immediately adjacent the left hand end of fold line 54 in main panel 50. The cutaway area 57 is for the purpose of eliminating bulky and cumbersome material at the junction between the adjacent edges of the main panel 50 and complementary panel 51 and thereby to facilitate the medial folding of the composite panel.

According to another facet of the invention, the left hand of main panel 54 is stepped as indicated at 58 so that the adjacent edge 59 of complementary panel 51 is spaced slightly without any overlap from the edge 58 of main panel 50. Thus when the carton is completely formed with the lower edge of the

composite panel

50, 51 secured in face contacting relation to the glue flap 2, as shown in FIG. 5, the

adjacent edges

58 and 59 will lie in the same plane and by this means a secure junction between glue flap 2 and

panels

50 and 51 is obtained.

The carrier blank depicted in FIG. 2 is first treated with an application of glue as indicated by stippled areas. Thereafter the

end panels

4 and 34 are swung upwardly and toward the right along the fold lines 5 and 37 to cause the

handle panels

12 and 13 to fall into fiat face contacting relation with the inner surfaces of the

handle panels

14 and 15 as shown in FIG. 3. Simultaneously the inner ends of

riser panels

8 and 30 become adhered to the inner surfaces of

handle panels

12 and 13. The complementary panel 51 as already explained is folded upwardly and toward the right along fold line 52 and occupies the position depicted in FIG. 3.

It will be understood that the folding of

end panels

4 and 34 and associated structure may precede or follow or be simultaneous with the folding of complementary panel 51 to the position depicted in FIG. 3. If the folding is simultaneous, it may be desirable temporarily to interconnect the bottom edge of end panel 34 with the adjacent side edge of complementary panel 51 by suitable nicks in well known manner.

After the parts are folded to the positions depicted in FIG. 3, an application of glue is made to the riser panels and 32 and if desired to the inner surfaces of the handle panels 14 and as indicated by stippling in FIG. 3. Thereafter, the

riser panels

10 and 32 are folded upwardly and toward the left along the

fold lines

11 and 33 respectively to occupy the positions depicted in FIG. 4. Simultaneously the composite bottom panel is folded along the

medial fold lines

53 and 54 to occupy the position depicted in FIG. 4.

Thereafter an application of glue is made to the blank as depicted by setippling in FIG. 4. Following the application of glue as indicated in FIG. 4, the side wall 1 and all the panels associated therewith above the

medial fold lines

16 and 17 are lifted and swung forwardly to occupy the positions of the blank depicted in collapsed form in FIG. 5.

In order to set up the carried depicted in FIG. 5 into the condition depicted in FIG. 1, it is simply necessary to exert a force toward the left along the right hand edge of end panel 6 while exerting a force toward the left along the end edge of side wall 1. When the

notches

55 and 56 engage the

notches

45, 47 and 46, 48 the carrier is retained in its set-up condition.
