Abstract
Description
- It is currently known to ship or store fluid material in either a large rigid cylindrical drum (e.g., a large metal drum) or a large paperboard container having a seated inner fluid bag. One such paperboard container is described in U.S. Pat. No. 6,786,394, and presently assigned to Weyerhaeuser Company, Federal Way, Wash. While such containers are sufficient for their intended purpose, the packaging industry is always in need for improvements for known containers. As will be described in the detailed description below, containers formed in accordance with aspects of the present invention are directed to such improvements.
- This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
- In accordance with aspects of the present invention, a paperboard container having a collapsed state and an open erected state is provided. The container comprises an inner sleeve having opposed side panels, opposed end panels, and including an exterior surface and an interior surface. The container also includes an outer sleeve having opposed side panels and opposed end panels, and having an exterior surface and an interior surface. As assembled, the inner sleeve is positioned within the outer sleeve and the exterior surface of the inner sleeve side panels and/or end panels are adhered to the interior surface of the outer sleeve side panels and/or end panels, respectively. The outer sleeve includes a bottom flap hingedly connected to one of the outer sleeve side or end panels. As assembled for use, the bottom flap forms a pocket disposed on the interior surface of the outer sleeve.

Embodiments of the present invention are generally directed to containers, for example, paperboard containers, suitable for use in the packaging and shipping industry. In accordance with features described herein, embodiments of the container are particularly well suited for use with a conventional fluid bag having a nozzle and fitment. The bag may be placed in the container as described below and filled with a fluid material. As used herein, the term “fluid” refers to a material that behaves in a fluid manner, i.e., a liquid, plasma, dry dispensable material, etc.
-
FIGS. 1 and 2 illustrate one suitable embodiment of acontainer 10 formed in accordance with aspects of the present invention. As best shown inFIGS. 1 and 2 , thecontainer 10 is generally rectangular in shape, thereby formingside walls 12 and 14 (hidden inFIG. 1 ), andend walls 16 and 18 (hidden inFIG. 1 ), atop 20, and abottom 22. Thecontainer 10 includes apocket 24 located on the interior of one of the walls, such as theend wall 16, adjacent thebottom 22. Thecontainer 10 further includes anaccess flap 26 formed in the wall corresponding to thepocket 24. Theaccess flap 26 acts like a door for selectively providing access to thepocket 24 from the exterior of thecontainer 10. - In an embodiment, the
container 10 is configured so as to have a flat, collapsed or “knock down” condition and an erect condition. In use, thecontainer 10 is shipped to a customer in the collapsed condition. Once received, the customer can easily store the flat containers in large quantity, without significant cost. To use, the customer erects thecontainer 10 by pushing opposite side corners toward one another. - As stated above, the
container 10 is particularly well suited for use with a conventional fluid storage bag, thereby forming packaging suitable for the shipment and storage of non hazardous fluids. As best shown inFIGS. 1 and 2 , a conventionalfluid storage bag 30 is placed within the interior cavity of anerect container 10 by, for example, the customer. Thebag 30 is oriented such that the bag'snozzle 32 andfitment 34 extend outwardly into thepocket 24. Thebag 30 may then be filled with the desired fluid in a conventional manner to be either shipped or stored. In use, the pocket protects the nozzle/fitment of thebag 30 and any valve spigots, etc. employed to selectively remove the contents of thebag 30. - In one embodiment, the
container 10 is capable of holding approximately 55-gallons (or approximately 200 liters) of fluid material and is sized so that four of such containers fit on a standard U.S. 40-inch by 48 inch pallet or metric 1200 mm by 1000 mm pallet. Other sizes are also contemplated to be within the scope of the present invention, as defined by the claims. - Due to the weight associated with storing or transporting fluid within the
bag 30, the container walls (i.e., side walls, end walls, top, bottom, etc.) are suitably configured with the appropriate dimensional stability and strength (e.g., stacking strength, bulge resistance, etc.) for its intended purpose. For example, the container may be made to one of many specifications using different grades of container material, such as paperboard stock. In one embodiment, the walls of the container may be formed as a single wall or double wall corrugated paperboard with reinforcement liners or sleeves. In one suitable embodiment, the walls of thecontainer 10 are formed from aninner sleeve 36 laminated to anouter sleeve 38, both of which are constructed of double wall corrugated paperboard. The term “inner container” is used herein to refer to that portion of the container formed by theinner sleeve 36. The term “outer container” is used herein to refer to that portion of the container formed by theouter sleeve 38. - Referring now to
FIG. 3 , there is shown one embodiment of a paperboard blank 36B suitable for forming the inner sleeve. The blank 36B includes a number of side panels distinguished from one another by hinge lines (e.g., 8-point wide crush scores). As shown inFIG. 3 , the blank 36B has a series of fourpanels glue joint panel 52 hinged to one end of the series. In the embodiment shown, one of thepanels 48 is wider than the other panels. Thispanel 48 forms the side wall of the inner container, as shown assembled inFIG. 5C . The twopanels panel 48, thereby forming the end walls of the inner container. The remainingpanel 44, in conjunction with the gluejoint panel 52, form the opposite side wall of the inner container, as assembled. - The inner sleeve blank 36B further includes a cut-out 60 disposed at the bottom of
panels horizontal edge 64, andvertical edges FIG. 3 , thehorizontal edge 64 extends the entire width of thepanel 46 and into thepanels 44 and 48 a selected distance. As will be described in detail below, the selected distance is one that cooperates with the depth of the protective pocket as assembled. The blank 36B may further include areference slot 70 along the hinge line between thepanels container 10. - In one embodiment, the
end panels end panel 46 is approximately 18½ inches wide and theother end panel 50 is about 18⅜ inches wide). Theside panel 44 is also nearly the same width (e.g., 18⅛ inches wide) as theend panels side panel 48 is somewhat wider at about 22½ inches wide. In this embodiment, the length of the panels is about 35 inches while the horizontal edge of the cut-out is 22½ inches long and the vertical edges are 6 inches long. The blank 36B may be made from any suitable material, such as paperboard or the like. In one embodiment, the blank 36B is made from double wall corrugated paperboard. - Referring now to
FIG. 4 , there is shown one embodiment of a paperboard blank 3813 suitable for forming the outer sleeve of thecontainer 10. The outer sleeve blank 38B includes a series of fourpanels joint panel 88, each preferably defined from one another by hinge lines (e.g., 8-point wide crush scores). Two of the fourpanels wider panels panels 44 and 48) when the inner and outer sleeves are joined during assembly. The remaining twoouter sleeve panels side panels - The blank 3818 also includes four
top flaps flaps sleeve side panels top flaps sleeve end panels sleeve end panels sleeve side panels - Still referring to
FIG. 4 , the outer sleeve blank 38B also includes fourbottom flaps side panels bottom flap 106 that is hingedly connected to theend panel 86. The bottom flaps 100 and 104 are sized so as to overlap each other. Outer cuts made to define the upper and bottom flaps of the outer sleeve blank 38B may be made parallel to one another or tapered as shown inFIG. 4 . A number of holes, handles, or other openings may be formed in the container to aid in moving the container, if desired. - The blank 38B further includes the
access flap 26 formed inend panel 82. Theaccess flap 26 is formed by cut lines or perforated lines that extend from the hinge line betweenflap 102 andpanel 82. Thus, theaccess flap 26 folds about the hinge line betweenflap 102 andpanel 82. Theaccess flap 26 may be easily moved to the position shown inFIG. 1 for providing access to thebag nozzle 34. The size of the opening formed by theaccess flap 26 should be large enough to provide enough space for other valve components to be attached. - In one embodiment, the
side panels side panel 80 is approximately 22⅜ inches wide and theother side panel 84 is about 22½ inches wide), and have the same length (e.g., 37 inches). Theend panels end panel 82 is approximately 18½ inches wide and theother end panel 66 is about 18⅜ inches wide), and have the same length (e.g., 36 inches). In this embodiment, the top flaps 90 and 94 have the same length (e.g., 9½ inches) andtop flaps bottom flaps - In accordance with aspects of the present invention, the
container 10 includes a recessedpocket 24 for protecting thenozzle 32 andfitment 34 of thebag 26 once assembled by, for example, the customer. To that end, thebottom flap 82, which has not been used for closure of the bottom 22 of thecontainer 10, is configured with threepanels flap 82 and delineated by hinge lines disposed substantially perpendicular to the hinge lines disposed between panels 80-86. As shown inFIG. 4 , thecentral panel 112 is flanked byshorter panels pocket 24, as assembled. Thecentral panel 112 further includes a cut-out 120, such as a circular cut-out, sized large enough to pass thefitment 34 of thebag 30. - The
panel 82 further includes left andright flaps panel 114, and are hingedly connected thereto, via hinge lines. AU-shaped lock plate 130 is formed betweenflaps lock plate 48 to be easily separated from theflaps - Turning now to
FIGS. 5A-7C , there is shown one suitable method for assembling thecontainer 10. First, the inner andouter sleeve blanks blanks inner sleeve 36 shown inFIG. 5C , theinner sleeve bank 36B is laid laterally with its interior surface facing upward, and then is sequentially folded along the hinge lines between panels 44-50, as shown inFIG. 5B , until thepanel 44 overlaps the gluejoint panel 52, as shown inFIG. 5C . It will be appreciated that glue or other type of adhesive is placed at select locations along the exterior surface of thepanel 52 so that thepanel 52 is secured to thepanel 44. While the gluejoint panel 52 is shown inside of thepanel 44 inFIG. 5C , it will be appreciated that thepanel 52 could be secured on the outside of thepanel 44. - Glue or other types of adhesive is then placed at select locations along either the interior surface of the outer sleeve panels 80-86 or the exterior surfaces of the inner sleeve panels 44-50. Next, the
inner sleeve 36 ofFIG. 5C is placed on the interior surface of the partially folded outer sleeve blank 38B in the orientation shown inFIG. 6A . Alternatively, it will be appreciated that theinner sleeve 36 may be placed on the outer sleeve blank 38B in its substantially planar configuration ofFIG. 3 . For proper alignment, theregistration slot 70 may be utilized at this time to align with a designated reference hinge line, such as the hinge line betweenpanel 82 andpanel 84, of theouter sleeve 38. Once theinner sleeve 36 is placed onto the outer sleeve blank so that thepanels panels panel 86 adheres to thepanel 48 and thepanel 86 adheres to thepanel 50. Finally, the gluejoint panel 88 is adhered to the outer surface of thepanel 80. The final assembled container is shown in its erected configuration inFIG. 6B . - In an alternative method for assembling the
container 10 shown inFIG. 8 , the inner sleeve blank 36B is laminated to the outer sleeve blank 38B prior to folding the blanks into their rectangular configuration. Once the inner sleeve blank 3613 is laminated to the outer sleeve bank 388 in the orientation shown inFIG. 8 , the laminated blanks may then be folded about suitable hinge lines to form the container configuration ofFIG. 6B . - As discussed above, the assembled
container 10 also has a flat, collapsed or “knock down” state by folding the assembled container about alternating hinge lines. Thecollapsed container 10 may be shipped to a customer, without taking significant space. Once at the customer, thecontainer 10 may be easily stored until the container is ready for use. To fill thecontainer 10, the customer pushes the folded side edges of the collapsed container toward one another. This causes the interior space of thecontainer 10 to open up, with the inner and outer sleeves generally forming a rectangular shape. - Turning the container upside down, the customer inserts the
nozzle 32 andfitment 34 of thefluid bag 30 through thecutout 120 of thebottom flap 102 of the outer container from the exterior side thereof. TheU-shaped lock plate 130 is then removed from theflaps fitment 34, as shown inFIG. 2 , thereby securing thefitment 34 andnozzle 32 to thebottom flap 102 in a removable manner. As such, theU-shaped lock plate 130 ensures the continued placement of thefitment 50 through the cut-out 120. - The customer then forms the
pocket 24 by folding thebottom flap 102, beginning with theouter flaps container 10, as sequentially shown inFIGS. 7A and 7B . During this movement, thebottom flap 102 folds sequentially about its hinge lines formed between thepanels outer flaps panel 82 of the outer container. Once the pocket is formed, thebag 30 is disposed within the inner cavity of the container 10 (SeeFIGS. 1 and 2 ). It will be appreciated that thepocket 24, once formed, is held in this position by the shoulders formed by the cut-out 60 of the inner container. By utilizing the cut-out 60 for securing the bottom flap in its pocket orientation instead of using more permanent means, thebag 30 may be removed from thebottom flap 102 by unfolding thepocket 24 and removing thelock plate 130. Thebag 30 may then be discarded while thecontainer 10 may be reused or recycled. Alternatively, the pocket may be permanently formed by gluing the outer flaps to the interior wall surface of thepanel 82. - The customer continues erecting the
container 10 by folding and sealing the bottom flaps 100, 104, and 106 to close the bottom 22 of thecontainer 10. The bottom flaps 100, 104, and 106 are made to be oversized so that the flaps easily overlap one another, thereby increasing the strength of the bottom 22 of thecontainer 10. Thecontainer 10 is then turned right side up and placed on a pallet. Next, thebag 30 is filled with the desired material. Thecontainer 10 is then closed at its top 20 viatop flaps access flap 26 to expose thebag nozzle 32 andfitment 34, as shown inFIGS. 1 and 2 . An operator may then place a conventional valve spigot on the nozzle/fitment, and proceed with dispensing the contents of thebag 30. - While exemplary embodiments of the present invention have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention, as claimed. For example, embodiments of the present invention may be made in any number of sizes with capability to handle various volumes. Also, although embodiments of the present invention are described herein as sized to fit on various standard sized pallets, the container may be made to fit a non-standard size using other dimensions. Further, while the pocket is formed by one of the end panel flaps, the pocket may suitable be made from one of the side panel flaps.
- Even further, by way of example, the terms “adhesive”, “adhering”, etc. are meant to refer to any method of connecting two or more panels to one another in a manner that precludes significant movement between the panels. Though glue or lamination is the preferred method of adhesion, other types of known connective methods may be used, depending on the circumstances of a particular application. By way of still another example, the stacking strength of the container may be increased by placing one or more upright tubes (not shown) or the like within the interior of the container. Similarly, top and/or bottom plates (not shown) may be inserted at the container ends to transmit loads between corners.
