United States FOUR-BOTTLE COLLAPSIBLE CARRIER Application June 20, 1955, Serial No. 516,664

2 Claims. (Cl. 220-113) This invention relates generally to a collapsible bottle-carrier, and more particularly to an improved carrier construction formed from a single sheet of cardboard or like foldable material.

In the design and construction of collapsible bottlecarriers of the general type disclosed by the present invention, several structural requirements must be given careful consideration. First, it is necessary to define a plurality of bottle-receiving compartments separated by means of foldably collapsible partition elements. Second, it is necessary to provide a side wall and bottom wall assembly of substantial strength and rigidity. Third, it is necessary to provide some manual carrying means in the form of a handle or the like, having substantial strength and durability. Fourth, it is desirable to provide means for maintaining the carrier in rigidly fixed, erect position for receiving bottles therein.

For purposes of easy and low-cost mass production, it is a further important consideration to form a collapsible bottle-carrier of unitary form from a single sheet of cardboard or like foldable material, which is particularly cut, scored, and coated with glue to enable initial assembly by a series of simple folding operations.

It is a primary object of this invention to provide a collapsible carrier construction adapted to be formed from a single sheet of foldable material, and having the structural attributes of partition means, handle means, wall reinforcement, and erection lock means.

It is another object of this invention to provide a four-compartment collapsible bottle-carrier formed from a single piece of flat stock such as cardboard or like foldable material, which is particularly cut, folded, glued, and self-reinforced to provide a container of high strength and structural rigidity when erect, and which is readily capable of being collapsed into flat, folded relation.

It is a further object of this invention to provide a collapsible bottle-carrier having foldably collapsible partition means providing structural elements adapted to cooperate with bottom wall reinforcing means for effecting a locking of the carrier in erect position.

It is still another object of this invention to provide a collapsible bottle-carrier having bottom wall reinforcing means secured to and relatively foldable away from the bottom wall.

Further objects and advantages of this invention will become apparent as the following description proceeds and the features of novelty which characterize this invention will be pointed out with particularity in the claims annexed to and forming part of this specification.

A preferred embodiment of the invention is shown in the accompanying drawing, in which:

Figure 1 is a perspective View of a four-compartment bottle-carrier constructed in accordance with the present invention and shown in erected position for receiving a plurality of bottles therein, portions being broken away to show details of construction;

* atent Figure 2 is a top view of the bottle-carrier of Figure 1 shown in near fully collapsed relation;

Figure 3 is a layout view of a single piece of sheet stock which has been appropriately cut, scored for folding, and coated with glue for subsequent assembly ,to form the carrier shown in Figures 1 and 2 Figures 4 through 6 are plan views on a reduced scale showing the consecutive folding steps to be performed on the pattern of Figure 3 for providing the final bottlecarrier structure; and

'Figure 7 is a top plan view on a reduced scale of the bottle-carrier in fully erect relation.

Referring now more particularly to Figure l of the drawing, I have shown a four-compartment collapsible bottle-carrier 10 having peripherally continuous side walls 12, contiguous bottom wall portions 14, intersecting center and

cross partitions

16 and 18, and carrying handle portions 20.

As best seen in Figure 3, a single integral pattern 22 is cut from a flat sheet of cardboard stock or like foldable material. The pattern 22 defines first

side panelforming portions

24 and 26, a second side panel 28, third side panel-forming

portions

30 and 32, and a fourth side panel 34.

Intermediate fold lines

27, 29, 31, and 33 serve to define the four corners of the bottle-carrier 10 when disposed in its generally rectangular erect position.

The center partition 16 is formed by two mated pairs of half-panels in aligned, abutting relation. A first pair of these half-panels is provided by

end portions

36 and 38 of the pattern 22. The

panels

36 and 38 are bendable relative to the

adjacent panels

30, 32 along

fold lines

35, 37, and are of substantially identical complementary form for mating engagement with each other to provide one of the half-portions of the center partition 16.

The cross partition '18 is formed by a pair of

end panels

40 and 42 at the other end of the panel 22. The

panels

40 and 42 terminate in

connector flaps

44 and 46 having glue surfaces 48 and 50, respectively, for rigid attachment to corresponding side walls, as will hereinafter appear. Fold lines 49 and 51 permit bending movement between the

flaps

44, 46 and the

corresponding end panels

40, 42.

The other half-portion of the center partition 16 is formed by half-

panels

52 and 54, of substantially identical complementary form for mating engagement with each other.

End panels

40, 42 are bendable relative to the half-

panels

52, 54 along fold lines 53, 55. The

halfpanels

52 and 54 also provide handle-forming

extensions

56 and 58, respectively, extending outwardly beyond the adjacent edges of the side wall panels. The

extensions

56 and 58 are cut away at 60 and 62, respectively, to accommodate the formation of the carrier handle 20,

The center partition half-

panels

36 and 38 similarly provide handle-forming

extensions

64 and 66, respectively, which are cut away at 68 and 70 for formation of the carrier handle 20.

Extended portions of the side wall panels 24 and 34- serve to define a bonding flap 72, separated therefrom by cut lines 71, but contiguous with the handle forming extension 56. The

side wall panels

26 and 28 similarly provide a complementary bonding flap 74, separated by cut lines 73 and contiguous with the handleforming extensions 58.

Fold lines

73 and 75 afford bending movement of the

bonding flaps

72 and 74 relative to the handle-forming

extensions

56 and 58. The

bonding flaps

72 and 74 are cut away at 76 and 78, respectively, to provide a suitable hand grip for manually supporting the bottle-carrier by the handle 20.

The handle-forming

extensions

56 and 58 are coated with glue at 80 and 82, respectively. Similarly, the

handle forming extensions

64 and 66 are coated with glue at 84 and 86, respectively.

A bottom wall 90 extends contiguously between the

side panels

28 and 34, and is bendable relative thereto along fold lines 89 and 91. Adjacent the bottom wall 90 and intermediate the third side panel-forming

portions

30 and 32, a pair of contiguously extending reinforcing

flaps

92 and 94 are provided, with a cut away or separation 96 therebetween. Cut

lines

93 and 95 of particular form extend within the

flaps

92 and 94, respectively, from each point of intersection with the corresponding adjacent bottom and side panels. The flap 92 is particularly formed to provide a hook extension 98. The center

partition half panels

36 and 38 are notched at 100 and 102 for cooperation with the hook 98 in a manner to be hereinafter described. A reinforcing flap 104 extends between the

cross partition panels

40 and 42, and is bendable relative thereto along

fold lines

103 and 105.

Glue surfaces

106, 108, 110, and 112 are provided by suitable coating of the reinforcing

flaps

92, 94, and 104.

Fold lines

107 and 109 are provided intermediate the

flaps

92, 94 and the adjacent bottom wall 90 for bending movement therebetween. Similarly,

fold lines

111 and 113 are provided to permit bending movement of the

flaps

92, 94 relative to the

panels

30 and 32.

Referring now more particularly to Figures 4 through 6 of the drawing, a consecutive series of folding and gluing steps to be performed on the pattern of Figure 3 will be described to illustrate the formation of the completed bottle-carrier structure shown in Figures 1 and 2.

The first folding step is made along

fold lines

73 and 75 which extend inwardly between side-forming panel 24 and center partition half-panel 52, and between sideforming panel 26 and center partition half-panel 54, respectively. When this folding is completed, as shown in Figure 4, the handle-forming

extensions

56 and 58 will be glued to the

bonding flaps

72 and 74, respectively. It should be noted that the

fold lines

73 and 75 permit the

panels

52 and 54 to be freely swingable relative to the

panels

24 and 26, respectively, without restriction by the

bonding flaps

72 and 74 which are separated from the adjacent side panels by means of the

cut lines

73 and 75. The cut-

outs

60 and 62 will register with the adjacent half-portions of the cut-

outs

76 and 78 to define a single opening therethrough. The

connector flaps

44 and 46 will be glued to the

side panel

28 and 34, respectively, substantially intermediate their widths. The reinforcing flap 104 will be glued to the bottom wall 90, the glue area 110 lying within a flap half-portion 104a which registers with an aligned half portion 90:: of the bottom 90, and the glue area 112 lying within a flap half-portion which registers with an aligned bottom half portion 90b.

The second folding step is made along

fold lines

29, 31, and 107, 109. When this folding is completed, as shown in Figure 5, the handle-forming

extensions

64 and 66 will be glued to the remaining exposed halves of the

bonding flaps

72 and 74, respectively. In addition, the glue surfaces 106 and 108 of the reinforcing

flaps

92 and 94 will be glued to the bottom portions 90a and 90b, respectively. The hook 98 will freely overlap an adjacent portion of the reinforcing flap 104.

As clearly seen in Figures 4 and 5, the first folding serves to expose an underlying glue surface 120 of the center partition half-panel 54 and the handle-forming extension 58. Similarly, as seen in Figure 5, the second folding serves to expose an underlying glue surface 122 of the center partition half-panel 38 and the handle-forming extension 66.

The third folding step is made along

fold lines

124 and 126 which mark boundaries between the portions 90a and 90b of bottom 90, and the portions 104a and 104]) of flap 104, respectively. After the third folding has been made, along the

lines

124 and 126, the center partition half-

panels

36 and 52 will be glued to the cross panels 4 38 and 54. Also, the handle-forming

extensions

56 and 64 will be glued to the

cross extensions

58 and 66. This final folding step completes the assembly of the carrier, resulting in a collapsible four-sided container of generally rectangular form, having a center partition of two-ply thickness, which provides an upwardly extending carrying handle of four-ply thickness, and a cross partition between the center partition and the opposite adjacent side walls.

The structural formation of the bottom wall 90 and the rc-inforcement thereof by the

flaps

92, 94, and 104 constitutes a particularly important aspect of the present invention. As best seen in Figure 3 of the drawing, the

re-inforcement flaps

92 and 94 are provided with foldlines which serve to divide each of the flaps into three distinct areas. For this purpose, re-inforcing flap 92 is scored at 128a and 128k. Similarly, re-inforcing flap 94 is scored at 130a and 130b. The fold-lines 128b and 13% extend inwardly from the corresponding flap edges to intersect with the cut-

lines

93 and 95, respectively. In this same way, the reinforcement flap portions 104a and 10% are provided with fold lines 132a, 134a and 132b, 134b, respectively, serving to divide each of the flap portions into three distinct areas.

The glue surfaces 106, 108, 110 and 112 are each confined within a single one-third area of the corresponding reinforcing flaps. The three one-third areas of each of the reinforcing flaps are foldable relative to each other and relative to the adjacent portions of the pattern 22. It will be apparent that after complete folding assembly of the carrier the glue surfaces will serve to fixedly secure the glued one-third area of each reinforcing flap to the bottom wall 90. The two remaining freely foldable onethird areas of each of the reinforcing flaps together provide an additional material thickness overlying the glueattached one-third area when the carrier is disposed in erect position, as clearly seen in Figure 7. These folding reinforcement areas permit free bending movement of the bottom wall portions a and 90b toward each other, and cooperative folding of the side wall and center partition elements in cooperation therewith. In this way, the carrier may be readily folded'into its flat storage posltion, and also expanded into its erect use position, with me various bottom reinforcing flaps folding from collapsed to operative positions required.

As best seen in Figure 1 of the drawing, the hook 90a formed by the reinforcing flap 92 is received within the recess formed by mated notches and 102 of the center partition 16, when the carrier is expanded to its erect position. The particular folding relation of the freely bendable one-third areas of the reinforcing flap 92 serve to effect a pivotal upward and outward movement of the hook 98 into the

notches

100, 102 as the bottom wall portions 90a and 90b move upwardly toward the center partition 16 to form a substantially flat bottom wall. In this way, automatic coupling of the center partition 16 and bottom wall 90 to effect locking of the carrier in erect position is acccomplished and maintained by the hook 98. Upon folding of the carrier to a collapsed position, the hook 98 moves pivotally in the opposite manner, thereby releasing the interlock between the center partition 16 and bottom wall 90.

By the present invention I have provided a four-bottle carrier of sturdy and reliable construction having substantially reinforced bottom wall strength and automatic locking means for effecting rigid cooperation of the reinforced bottom wall and the center partition means.

Changes may be made in the construction and arrangement of the parts of my four-bottle collapsible carrier without departing from the real spirit and purpose of my invention, and it is my intention to cover by the claims any modified forms of structure or use of mechanical improvements which may be reasonably included within their scope.
