Definitions
- the invention relates to containers used for packaging, shipping and displaying goods. More particularly, the invention relates to display containers such as corrugated paperboard boxes having flanges to facilitate the stacking of such containers on top of one another.
- Display containers for example, boxes of corrugated paperboard, are widely used for shipping and marketing products. Such containers are especially popular in warehouse-type marketing settings and supermarkets where many containers are stacked on top of one another and have open tops and partially open sides to display the food or merchandise held within them. Examples include containers of packaged candy which may be decorated for display purposes. The containers of candy are shipped to the store in stacked form. Store personnel remove the tops of the containers and, in many cases, fold down or remove a side display panel from the container which exposes the candy within the container to view and allows access thereto by the consumer. The containers are then stacked one on top of another on the retail floor for display of the candy to the consumer.
- a major problem with stacked containers having open tops and sides is that a container may partially fall into or “nest” within the container beneath it.
- Another problem is the lack of strength for stacking. All too often loaded containers near or at the bottom of a stack collapse or become misshapen under the weight of the containers above them. This impairs the aesthetic appearance of the display sought by the seller, ruins the products within, and requires clean up.
- One known container disclosed in U.S. Pat. No. 5,791,555, and which is hereby incorporated by reference, provides a shelf like flap to help support a container stacked on top and prevent nesting.
- This container is configured to automatically pull the shelf into position upon the assembly of the container.
- One end of the shelf is connected to a side wall of the container to pull the shelf down, the other end being free and typically resting on the top of one of the side walls. While this container provides advantages over other type containers, further improvements are believed desirable. For example, many products, such as candy, are drop loaded into the containers. If the shelf is already in place, this can interfere with the loading process. Furthermore, it has been found that in some uses the free end of the shelf can be forced into the container, creating a nesting problem.
- the invention concerns a container upon which another container having similar dimensions may be stacked without nesting in the container.
- the container comprises a plurality of panels attached to one another along adjacent edges to form a plurality of sidewalls surrounding a central space.
- a plurality of flaps extend from the sidewalls inwardly toward the central space, the flaps being positioned substantially co-planarly in one of overlapping and adjacent positions relative to one another to form a bottom.
- a first flange is attached to a first of the sidewalls along an edge thereof positioned opposite to the bottom.
- a second flange is attached to a second of the sidewalls along an edge thereof positioned opposite to the bottom, the second sidewall being attached to the first sidewall, the second flange being attached to the first flange along a common edge.
- the first flange is oriented substantially parallel to the bottom and extends inwardly toward the central space for supporting the other container when stacked thereon.
- the second flange is folded along a fold line oriented at an angle to the common edge, the second flange being thereby divided into overlying flange portions.
- Each of the overlying flange portions has an outer face, the outer faces being attached to one another in face to face relationship, thereby holding the first flange in position substantially parallel to the bottom. Attachment of the faces is preferably by adhesive.
- the invention also concerns support surfaces useable on containers to permit stacking of the containers one atop another without nesting.
- the containers comprise a plurality of interconnected panels forming sidewalls surrounding a central space.
- the sidewalls have flaps extending therefrom which are foldable to form a bottom.
- First and second support flanges are respectively attached to first and second sidewalls which face one another in opposing relationship.
- the support flanges extend lengthwise along edges of the sidewalls in spaced relation to the bottom.
- the support flanges are each oriented at a substantially right angle to the first and second sidewalls and project inwardly toward the central space.
- Side flanges are attached to each end of the first and second flanges.
- Each side flange is also attached to a respective sidewall adjacent to one of the first and second sidewalls.
- the side flanges are folded along respective fold lines extending diagonally across each side flange, the fold lines dividing each of the side flanges into overlying flange portions facing one other and extending inwardly toward the central space, the overlying flange portions being adhered together, preferably by adhesive.
- one object of the present invention is to provide a display-ready container with improved anti-nesting capabilities.
- Another object is to provide a container with anti-nesting capabilities that can be assembled by machine.
- Another object is to provide a display-ready container that is economical to produce.
- a further object of the present invention is to provide a display-ready container that is easy to assemble and use.
- Another object is to provide a display-ready container that can be safely stacked during shipping and display.

- the flaps 30 , 32 , 34 and 36 are positioned substantially co-planarly in overlapping and adjacent positions relatively to one another.
- the sidewalls, flaps, fold down portions and other parts comprising the container 10 are joined together at adjacent edges defined by fold lines formed in the substrate comprising the container.
- the fold lines may be formed in any of a number of ways, such as by cutting, creasing or perforating the paperboard as is known in the art.
- the fold line and the edge are denoted by the same reference character. This does not imply, however, that all edges are necessarily fold lines or that all parts of the container need be joined at fold lines in the substrate.
- Containers 10 have support flanges 40 and 42 which form flat support surfaces 44 across the tops of the containers upon which other containers sit when the containers are stacked as illustrated in FIG. 1.
- the support flanges 40 and 42 prevent nesting of the containers within one another when stacked and also strengthen the container sidewalls against collapse.
- the support flanges 40 and 42 extend across the entire width or length of the container and are respectively positioned on opposing sidewalls such as 16 and 20 .
- Each support flange 40 and 42 is preferably integrally formed with its respective sidewall 16 and 20 and extends from a respective edge 74 and 92 located on each sidewall opposite to the bottom 38 of the container.
- the edges 74 and 92 are defined by respective fold lines in the container substrate which preferably have lengthwise perforations 46 along at least a portion of the span of the support flange.
- the perforations provide increased flexibility for folding the support flange without significantly compromising the strength of the flange attachment to its respective sidewall. Further details related to the construction of the support flanges 40 and 42 are provided below.
- Container 10 is preferably formed from a unitary substrate blank 48 , shown in FIG. 2.

- Sidewall 18 has a large cut-out region defining the display opening 28 in the sidewall for access to the container's central space once assembled.
- Sidewall 18 also has a fold down portion 26 , shown before folding, which reinforces the sidewall.
- fold down portion 26 is defined by two parallel cuts 60 and 62 respectively positioned at either end of the fold down portion, and a fold line 64 which extends lengthwise along the fold down portion between the cuts. Cuts 60 and 62 extend through the entire thickness of the substrate blank 48 to free the ends of the fold down portion 26 from the sidewall 18 and allow it to be reverse folded inwardly to reinforce the sidewall 18 .
- Sidewall 18 is joined to sidewall 20 along an edge defined by a fold line 66 .
- Flap 34 extends from a lower edge of sidewall 20 , that edge being defined by a fold line 68 .
- Sidewall 20 is joined to sidewall portion 22 b along an edge defined by a fold line 70 .
- Sidewall portion 22 b is the counterpart to sidewall portion 22 a , and when joined together, the sidewall portions 22 a and 22 b form sidewall 22 .
- a portion of flap 36 denoted 36 b , extends from a lower edge of the sidewall portion 22 b , that edge being defined by a fold line 72 .

- Support flange 40 extends from an upper edge of sidewall 16 , that edge being defined by a fold line 74 .
- Support flange 40 preferably runs along the entire length of sidewall 16 , and each end of the support flange is attached to a respective side flange 76 and 78 .
- Side flange 76 extends from an upper edge of sidewall portion 22 a , that edge being defined by a fold line 80 .
- Another fold line, 82 defines the edge between support flange 40 and the side flange 76 .

- Blank 48 is next formed into a knockdown 110 shown in FIG. 3A.
- the knockdown is advantageous because it allows containers such as container 10 to be shipped from the manufacturer in a flat configuration, saving space and reducing shipping costs.
- the knockdown is configured to be conveniently converted from the flat configuration into the container 10 as depicted in FIG. 1 through a series of simple steps (described below) performed by automated machinery. Once the container is formed from the knockdown, it is then loaded with merchandise, final actions are executed, and the container with its contents is ready for shipment.
- Knockdown 110 is formed by first reverse folding fold down portion 26 along fold line 64 and into overlying relation with the inwardly facing surface of sidewall 18 .
- Next blank 48 is reverse folded along fold lines 66 and 52 to bring sidewall portion 22 b into partial overlying relation with counterpart sidewall portion 22 a .
- the two sidewall portions 22 a and 22 b are bonded together, preferably with an adhesive 112 (see FIG. 1) to form sidewall 22 , and the knockdown 110 shown in FIG. 3A.
- Knockdown 110 comprises a first knockdown wall 114 formed of sidewalls 18 and 16 along with their respective flaps 32 and 30 as well as flanges 96 , 78 and 40 all aligned in a same first plane when the knockdown is in its flat configuration. Edges 66 and 52 form the first and second knockdown corners which define the ends of the first knockdown wall 114 .
- a second knockdown wall 116 is formed of sidewalls 20 and 22 , their respective flaps 34 and 36 , and flanges 42 , 94 and 76 all in a same second plane which is parallel to the first plane.
- the second knockdown wall 116 is joined to the first knockdown wall 114 at the first and second knockdown corners defined by edges 66 and 52 .
- FIGS. 3A through 3C show a series of steps performed to transform the knockdown 110 into the container 10 .
- the first and second knockdown walls 114 and 116 are separated from one another with the sidewalls 16 , 18 , 20 and 22 pivoting relatively to one another in the manner of a four bar linkage about fold lines 52 , 56 , 66 and 70 .
- the sidewalls comprising the respective knockdown walls 114 and 116 move outwardly they are no longer substantially in the same plane and the knockdown 110 transforms into the configuration shown in FIG. 3B wherein adjacent sidewalls are oriented at right angles to one another.
- flaps 30 , 32 , 34 and 36 are folded inwardly along respective fold lines 54 , 58 , 68 , 72 and 50 to form the bottom 38 .
- flaps 30 and 34 are first folded inwardly followed by flaps 32 and 36 , the latter two flaps being preferably adhesively bonded to the first two to form a permanent bottom.
- Other bottom configurations are of course feasible, as known in the art.
- an auxiliary panel (not shown) will be installed within the central space 24 in overlying relation with sidewall 18 to close off the opening 28 . The auxiliary panel is removed at the point of sale to display the container contents in the stacked configuration as shown in FIG. 1.
- the support flanges 40 and 42 are folded inwardly about respective fold lines 74 and 92 toward the central space 24 to provide the support surfaces 44 which strengthen the sidewalls and support a container stacked on top of the container 10 without allowing nesting of the containers.
- the side flange 78 is attached to both support flange 40 and sidewall 18
- side flange 76 is attached to both support flange 40 and sidewall 22
- the side flanges 78 and 76 are at right angles to support flange 40 .
- This configuration will generally prevent folding of support flange 40 about fold line 74 .
- fold lines 90 and 84 are positioned diagonally across side flanges 78 and 76 respectively.
- the fold lines 90 and 84 divide their respective side flanges 78 and 76 into respective overlying flange portions 78 a , 78 b , 76 a and 76 b .
- Each overlying flange portion has an outer surface 78 c , 78 d , 76 c and 76 d also shown in FIG. 2.
- the fold lines 90 and 84 allow the side flanges 78 and 76 to fold inwardly in the manner of a bellows or accordion pleat to respectively bring their outer faces 78 c , 78 d , 76 c and 76 d into face to face relationship as shown in FIG. 3C.
- Flanges 42 , 94 and 96 are similarly configured with fold lines 102 and 108 , forming respective overlying flange portions 94 a , 94 b , 96 a and 96 b .
- Each overlying flange portion has an outer surface 94 c , 94 d , 96 c and 96 d as shown in FIG. 2.
- the fold lines 102 and 108 allow their respective side flanges 94 and 96 to fold inwardly, permitting support flange 42 also to fold as described for support flange 40 .
- Adhesive 118 is applied between the outer facing surfaces 78 c , 78 d , 76 c , 76 d , 94 c , 94 d , 96 c and 96 d to secure them to one another in facing relationship and hold the support flanges 40 and 42 in the folded configuration. Adhering the faces together also serves to strengthen the container 10 , permitting deeper stacking without nesting or collapse. Side flanges 78 , 76 , 94 and 96 are preferably square in shape so as to minimize their size and yet provide a shape which will fold neatly within the perimeter of the container. The square shape allows the fold lines 76 , 78 , 102 and 108 to naturally be oriented diagonally and thus maximize the contact area when the flanges are folded to ensure good adhesion.
- a top (not shown) is placed on the container 10 and the container is ready for shipping. It is clear that the steps involved in forming the container from the knockdown, filling the container, folding and adhering the support flanges 40 and 42 in place and placing a top on the container are relatively simple steps occasioned by the design of the knockdown 110 which allows these steps to be performed rapidly and reliably by automated machinery.
- FIG. 4 shows another embodiment 120 of a container according to the invention.
- Container 120 has many of the same features as container 10 , and the same reference characters are used to identify those parts common to both embodiments.
- support flanges 40 and 42 are formed along edges 74 and 92 of opposite sidewalls 16 and 20 to strengthen the container 120 and provide support surfaces 44 to prevent nesting of containers one within the other when stacked.
- Container 120 has a divider panel 122 extending from sidewall 22 to opposite sidewall 18 .
- the divider panel 122 divides the central space 24 into separate regions 24 a and 24 b allowing the container to hold two different types of merchandise and keep them separated.
- sidewall 18 is a partial panel and has openings 28 a and 28 b providing access to each of the separate regions 24 a and 24 b when the containers are stacked together.
- Sidewall 18 has an upstanding middle extension 124 to which the divider panel 122 is attached.
- Container 120 is formed from a blank 126 shown in FIG. 5.
- Blank 126 is preferably die-cut from corrugated paperboard substrate and has fold lines defining the edges between sidewalls, flaps and flanges substantially as described above for container 10 .
- the panel surfaces visible in FIG. 5 are those which face outwardly from the central space when the container 120 is formed.
- divider panel 122 extends from sidewall portion 22 b , a fold line 128 defining the edge between the sidewall 22 b and the divider panel 122 .
- Divider panel 122 also has an attachment flap 130 positioned at its end opposite to sidewall portion 22 b and defined by a fold line 132 . As shown in FIG. 4, the attachment flap 130 is folded along fold line 132 at a right angle to divider panel 122 and attached to middle extension 124 to effect the attachment of divider panel 122 to the sidewall 18 . Attachment of flap 130 is preferably effected by adhesive.
- Knockdown 134 is shown in its flat configuration for shipping and has a first knockdown wall 136 comprising sidewalls 18 and 16 , their respective flaps 32 and 30 as well as flanges 96 , 78 and 40 in a substantially same first plane 138 .
- Fold lines 66 and 52 define the first knockdown wall 136 .
- a second knockdown wall 140 is attached to the first knockdown wall 136 at the fold lines 66 and 52 and is positioned in a substantially same second plane 142 parallel to and behind the first plane 138 .
- the second knockdown wall 140 comprises sidewalls 20 and 22 (formed by attaching sidewall portions 22 a and 22 b together) along with their flaps 34 and 36 and flanges 94 , 42 and 76 all substantially in second plane 142 , not all of which can be shown in FIG. 6.
- Knockdown 134 is transformed into the container 120 using substantially the same steps as described above for container 10 . Note that the divider panel 122 is sandwiched between the first and second knockdown walls 136 and 140 when the knockdown is in the flat configuration depicted in FIG. 6.
- the divider panel 122 pivots about its fold lines 128 and 132 similar to the way sidewalls 16 and 20 (to which it is parallel) pivot about their respective fold lines in the manner of a four-bar linkage to effect transformation from the knockdown to the container configuration.
- Containers according to the invention provide a convenient and cost effective item for packaging, transporting and displaying bulk items. Such containers are rugged and reliably stackable and avoid the problems of nesting and collapse from which other containers suffer.

Abstract
Containers are disclosed having a plurality of interconnected panels forming sidewalls surrounding a central space. Flaps extend from lower sidewall edges and fold along fold lines to form a bottom. Support flanges are arranged along upper sidewall edges on oppositely facing sidewalls. The support flanges are oriented at right angles to the sidewalls and provide a support surface allowing the containers to be stacked one atop another without collapsing or nesting within each other. Side flanges are attached to each end of the support flanges and to sidewalls joined to the sidewalls having the support flanges. The side flanges each have an angularly oriented fold line which divides the side flanges into facing portions and permits them to fold like a bellows or accordion pleat. The facing portions are adhered together to hold the support flanges in position.
Description
- This application is based on and claims the benefit of U.S. Provisional Application No. 60/354,099, filed Feb. 4, 2002.
- The invention relates to containers used for packaging, shipping and displaying goods. More particularly, the invention relates to display containers such as corrugated paperboard boxes having flanges to facilitate the stacking of such containers on top of one another.
- Display containers, for example, boxes of corrugated paperboard, are widely used for shipping and marketing products. Such containers are especially popular in warehouse-type marketing settings and supermarkets where many containers are stacked on top of one another and have open tops and partially open sides to display the food or merchandise held within them. Examples include containers of packaged candy which may be decorated for display purposes. The containers of candy are shipped to the store in stacked form. Store personnel remove the tops of the containers and, in many cases, fold down or remove a side display panel from the container which exposes the candy within the container to view and allows access thereto by the consumer. The containers are then stacked one on top of another on the retail floor for display of the candy to the consumer.
- A major problem with stacked containers having open tops and sides is that a container may partially fall into or “nest” within the container beneath it. Another problem is the lack of strength for stacking. All too often loaded containers near or at the bottom of a stack collapse or become misshapen under the weight of the containers above them. This impairs the aesthetic appearance of the display sought by the seller, ruins the products within, and requires clean up.
- One known container, disclosed in U.S. Pat. No. 5,791,555, and which is hereby incorporated by reference, provides a shelf like flap to help support a container stacked on top and prevent nesting. This container is configured to automatically pull the shelf into position upon the assembly of the container. One end of the shelf is connected to a side wall of the container to pull the shelf down, the other end being free and typically resting on the top of one of the side walls. While this container provides advantages over other type containers, further improvements are believed desirable. For example, many products, such as candy, are drop loaded into the containers. If the shelf is already in place, this can interfere with the loading process. Furthermore, it has been found that in some uses the free end of the shelf can be forced into the container, creating a nesting problem.
- The invention concerns a container upon which another container having similar dimensions may be stacked without nesting in the container. The container comprises a plurality of panels attached to one another along adjacent edges to form a plurality of sidewalls surrounding a central space. A plurality of flaps extend from the sidewalls inwardly toward the central space, the flaps being positioned substantially co-planarly in one of overlapping and adjacent positions relative to one another to form a bottom. A first flange is attached to a first of the sidewalls along an edge thereof positioned opposite to the bottom. A second flange is attached to a second of the sidewalls along an edge thereof positioned opposite to the bottom, the second sidewall being attached to the first sidewall, the second flange being attached to the first flange along a common edge.
