Description




TECHNICAL FIELD




The present invention relates generally to bulk material containers and specifically to reinforced corrugated flatboard containers for shipping liquid filled bags.




BACKGROUND OF THE INVENTION




Liquid products such as soft drink syrup or chemical products are often shipped in small volumes such as five gallon portions. These liquid volumes may be packaged in a plastic bag and housed within a paperboard container to protect the bag from puncture or compression. This method of packaging is often referred to as “bag in box.” The bag is often provided with a fitment or a spout and the box with a corresponding access door to allow access to the contents of the bag through a wall of the box.




Prior boxes that have been specially designed to enclose and transport these five gallon bags usually are six sided boxes folded from a single sheet of corrugated paper that is folded and glued along a single glue lap to an outside wall of the box. The boxes usually have bottom and top walls that are formed from the overlap of major and minor flaps, and the box usually folds flat for storage. The boxes also have a perforated section along an end wall that may be removed to accommodate the spout so that liquid may be removed from the bag without opening the top of the box.




However, these prior boxes have presented several problems to manufacturers and distributors. For example, distributors have discovered that these boxes have insufficient structural support and that movement of the liquid filled bag within the box may cause the box to unfold or breakdown during warehousing and distribution. Further, the boxes have inadequate stacking strength and may crush, or have its perforated spout break out or the box may otherwise be damaged under the weight of a palletized load. In more serious cases where the perforated spout breaks out, a tear may form in a side or end panel of the box and continue along paperboard corrugations causing the box to rip open. In these cases, the box is rendered incapable of protecting the contents of the bag from outside hazards.




Manufacturers and distributors have also encountered problems with this box. For example, the glue lap that was provided to hold prior boxes together, oftentimes became unglued during the loading of the box with a liquid filled bag causing the entire box to unfold. Further, the manufacturers have had difficulty in detecting leaks in these boxes until after the boxes have been filled and prepared for shipment or actually shipped. Manufacturers have also had difficulty, in loading the prior boxes, to get the liquid filled bags to cover the entire bottom of the box for even weight distribution.




Improvements have been made to the single piece containers by constructing a container from three separate pieces of corrugated paperboard. An example of such a container is disclosed in U.S. Pat. No. 5,143,278 which is assigned to the owner of the present invention and is incorporated herein by reference. The '278 Patent discloses a top loaded container which has reinforcing flanges that add considerable support to the container far in excess of single piece boxes. However, even the container disclosed in the '278 Patent must be stacked on a pallet with each box in conformation with the lower box, that is sidewall over sidewall and end wall over end wall, in a column stacking pattern to avoid damaging the container on panels


32


and


36


between side flanges


120


.




For these reasons, it is desirable to produce a more cost effective box for shipping liquid filled bags, that has greater stacking strength than boxes presently being used so that the boxes may be stacked on a pallet in an interlocking fashion, that is one box may be placed transverse to a lower box, or shipped in single increments by common courier such as U.P.S.




SUMMARY OF THE INVENTION




The present invention provides a reinforced corrugated paper box and corrugated paper blanks for forming the box that may be used for the shipment of liquid filled bags, and other bulk material.




According to the present invention, a container is provided having a polygonal-shaped sleeve defined by a double sidewall and a plurality of sidewalls. The double sidewall is defined by a first sidewall overlapping a last sidewall. Preferably, there are four sidewalls defining a rectangular sleeve. The sleeve has first and second ends, inner and outer surfaces, and a depth and a width dimension. The depth dimension is greater than the width dimension. The sleeve has a smooth inner surface. A first end wall located at the first end of the sleeve closes the first end of the sleeve. A second end wall located at the second end of the sleeve closes the second end of the sleeve.




An access door is provided in an end wall, preferably the second end wall, to allow access to the contents of a bag stored within the container. The door has a detachable section that preferably is circular in shape.




Preferably, the box has one or two holes in one of the walls of the container. These holes allow for the passage of air and liquid. Consequently, when a liquid filled bag is dropped into the box, air is displaced through the hole or holes allowing the contents of the bag to evenly distribute over the second end wall of the box. Also, the holes allow for early leak detection by allowing liquid to pass out of the box immediately after the leak occurs.




The present invention also provides for a system for forming the container described above. The system includes corrugated paper blanks for cooperatively forming the present container. To form the preferred rectangular container, the blanks comprise an elongate body blank with opposed lateral sides, and two side blanks each having opposed lateral sides, and opposed top and bottom ends. The container may also be formed using one side blank with two top ends, two lateral sides, and one bottom end. Transverse fold lines extending between the opposed lateral sides of the body blank divide the body blank into a first, a second, a third, a fourth and a fifth panel. Body flanges extend from the opposed lateral sides of the body blank from the second, third and fourth panel. These body flanges attach the body blank to the side blanks.




The side blanks preferably have top and bottom closing flaps that are foldable to form supports parallel to the stacking access of the container. Preferably the side blanks are made from two ply corrugated paperboard.




The three piece construction of the container allows one to interchange the stock of material used to build the container. For example, one could use a single ply corrugated paper for the body blank, and a double ply corrugated paper for the side blanks. The double ply corrugated paper sidewalls will add substantial structural support to the box.

DETAILED DESCRIPTION




While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail a preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiment illustrated.





FIG. 1

shows an elongate body blank


10


having first and second lateral sides


12


and


14


. Transverse fold lines


16




a-d


extend between the first and second lateral sides


12


and


14


to define a first, a second, a third, a fourth, and a fifth panel


30


,


32


,


34


,


36


, and


38


. The body blank


10


may be folded along the transverse fold lines


16




a-d


to form a C-shaped sleeve. Preferably the body blank


10


is made from single-ply corrugated paperboard.




Body flanges


40


extend from the first and second lateral sides


12


and


14


of the body blank


10


at the second, third, and fourth panels,


32


,


34


, and


36


. Marginal fold lines


42


separate the body flanges


40


from the body blank


10


.




Notches


44


are removed from the first and second lateral edges


12


and


14


of the body blank


10


at the intersection of the second and third panels


32


and


34


. The notches


44


provide a hole in the assembled container to allow for the passage of liquid and air.




The fifth panel


38


has a centrally located perforated section defining an access door


46


. An upper portion of the door is not perforated so that it may function as a hinge


48


. A circular shaped perforated section


50


at a distal end of the door


46


may be completely detached from the body blank


10


to form a circular hole. In the fully assembled container, the circular section


50


may be removed and the access door


46


pivoted outward to provide access to a fitment or spout of a bag (not shown) located within the assembled container. This access door


46


is not required when the assembled container is not used to ship liquid filled bags.





FIG. 2

shows a side blank


60


made of corrugated paperboard having a central panel


62


and top and bottom flaps


64


and


66


hingedly connected to the central panel


62


along respective creases


68


and


70


. The top flaps


64


may sometimes be referred to as minor flaps. A notch


72


is removed from a portion of the minor flap


64


to accommodate the passage of a spout of a bag enclosed within an assembled container. Preferably, the side blank is made from double ply corrugated paper for increased structural support. Further, preferably the paperboard corrugations extend laterally so that top and bottom flaps


64


and


66


fold more easily along creases


68


and


70


.




To erect a container


100


(

FIG. 3

) from the body blank


10


and the side blank


60


one must use one body blank


10


and two side blanks


60


. The body blank


10


is folded along the fold lines


16




b


and


16




c


to form a C-shaped sleeve. Two side blanks


60


are inserted into the C-shaped sleeve at opposite lateral edges


12


and


14


of the body blank adjacent the marginal fold lines


42


. Panels


32


and


36


and panels


62


(which sometimes may be referred to as sidewalls) of side blanks


60


define a rectangular sleeve


73


. The rectangular sleeve


73


has first and second ends


102


and


104


, and a depth and width dimension


106


and


108


. The depth dimension


106


should be greater than the width dimension


108


. (See FIG.


3


).




The bottom flaps


66


of each of the side blanks


60


are folded inward along creases


70


and the bottom flaps


66


are attached to an inner surface of panel


34


(which sometimes may be referred to as the first end wall as it closes the first end of the rectangular sleeve


73


) by gluing to form a double end wall. (FIG.


6


). The notches


72


of the side blank


60


must each be facing panel


38


so that when folded inward to close the container they are in alignment with the access door


46


. These notches are not required when the erected container is not used for shipping liquid filled bags.




The body flanges


40


along each lateral edge


12


and


14


of the body blank


10


are then folded inward along the marginal fold line


42


and attached to respective side blanks


60


by gluing. The flanges


40


form C-shaped supports


61


along a periphery of each of the side blanks


60


, two of the legs


75


of the C-shaped support extend from the first end


102


of the rectangular sleeve


73


toward the second end


104


of the sleeve


73


.




To close the second end


104


of rectangular sleeve


73


of the container


100


, the minor flaps


64


of the side blank


60


are folded inward of the sleeve


73


along the fold lines


68


(FIG.


4


). Then panels


30


and


38


, which may be referred to as major flaps, are folded inward on top of the minor flaps


64


and glued thereto (

FIG. 5

) to close the container


100


. If there is no access door


46


on container


100


, the second end


104


of the sleeve


73


may also be closed by initially folding panels


30


and


38


inward before folding minor flaps


64


.




When the container


100


is used to package a liquid filled plastic bag (not shown), the minor flaps


64


act as a plow to push the bag into the container


100


after loading. Further, the minor flaps


64


also serve to shield the bag from the damaging effects caused by contact with hot glue during the process of gluing the major flaps


30


and


38


to the minor flaps


64


.




In an alternate embodiment of the container


100


′, side blanks


60


′ shown in

FIG. 8

are used instead of the side blank


60


shown in FIG.


2


. Unlike side blank


60


(FIG.


2


), side blank


60


′ does not include bottom flaps


66


. Therefore, the first end wall


34


is of single thickness instead of double thickness. (FIG.


7


). In all other respects the containers are the same; thus, the same numerical designations are used for corresponding parts.




A second alternate embodiment, container


100


″ is shown in FIG.


14


. Container


100


″ is constructed from body blank


10


′, shown in

FIG. 11

, and single side blank


60


″, shown in

FIG. 12

, in essentially the same manner as described above with respect to container


100


. Unlike body blank


10


, body blank


10


′ has an oblong shaped hole


120


on panel


34


. Further, access door


46


is cooperatively formed by portions


46




a


and


46




b


located on respective panels


38


and


30


. For the sake of further clarity, body flanges


40


are more particularly referred to as


40




a-f.






Unlike prior side blanks


60


and


60


′ that have required the use of two side blanks


60


for each body blank


10


to construct a container


100


, only one side blank


60


″ per body blank


10


′ is required (FIG.


16


). Side blank


60


″ has side panels


62




a


and


62




b


, and an end panel


122


. End panel


122


has a centrally disposed frangible section


124


. Frangible section


124


overlays hole


120


of panel


34


, when constructed as a container


100


″, to define a positioning handle.




Side blank


60


″ has notches


72




a


and


72




b


removed, as do side blanks


60


and


60


′. Notches


72




a


and


72




b


generally conform to the outer contours of access door


46


as shown in FIG.


15


. The shape of notches


72




a


and


72




b


minimize the deleterious effects that may be caused by removal of paperboard to the structural integrity of the container. The shape of notches


72




a


and


72




b


also assists in minimizing the quantity of scrap material.





FIG. 13

shows yet another embodiment of side blank


60


′″. Side blank


60


′″ differs from side blank


60


′ in the shape of notch


72


. In all other respects


60


′″ is the same as


60


′ and may be used in the same fashion as


60


′ to construct a container


100


′″ as shown in FIG.


17


.




FIGS.


20


-


22


show another embodiment of container


100


′″ of the present invention. Container


100


′″ is constructed from body blank


10


″, shown in

FIG. 18

, and body blanks


60




IV


, shown in FIG.


19


. Unlike container


100


, container


100


′″ has four flanges (


40




a


,


40




c


,


40




d


,


40




f


) to form parallel supports, rather than the C-shaped supports shown in FIG.


5


. Also, there is a full overlap of fifth panel


38


over first panel


30


. Access door


46


in container


100


′″ overlays an aperture


74


in the first panel, to allow access to the contents of the bag. Minor flaps


64


are short enough so that they do not interfere with the passage of the spout of the bag through access door


46


. FIGS.


20


-


22


show container


100


′″ with both minor flaps folded to a closed position, with one major flap and both minor flaps folded to a closed position, and with both major and minor flaps folded to a closed position, respectively.





FIG. 24

shows another embodiment of the container


100




IV


of the present invention, constructed from body blank


10


′″, shown in FIG.


23


. The difference between container


100




IV


and container


100


is in the C-shaped support. Whereas flanges


40




b


and


40




e


in container


100


extend throughout the width of container


100


, in container


100




IV


, flange


40




b


lies between flanges


40




a


and


40




c


, and flange


40




e


lies between flanges


40




d


and


40




f


respectively.




FIGS.


28

show another embodiment of container


100




V


, constructed from body blank


10




IV


, shown in FIG.


25


and body flanges


60




V


and


60




VI


, shown in

FIGS. 26 and 27

, respectively. First panel


30


in body blank


10


″ is wider than fifth panel


38


, and has both access door


46


and frangible section


124


. Side blank


60




VI


also has an access door


46


′ to correspond with access door


46


. Access doors


46


and


46


′ act as a double lock to anchor the spout of the bag within access doors


46


and


46


′. Frangible section


124


overlays an oblong shaped hole


120


in side blank


60




V


to define a positioning handle above access door


46


. FIGS.


28


-


30


show container


100




V


in an open position, with both minor flaps folded to a closed position, and with both major and minor flaps folded to a closed position, respectively.





FIG. 31

shows an alternate embodiment of a body blank


10




V


. The body flange


40




a


in the body blank


10




V


has a cutout section


126


and a perforated section


128


defining a portion of an access door


46


. The cutout section


126


may also be defined as a perforated section, or, as shown in an alternate body blank


10




VI


in

FIG. 32

, a cutout section


130


may replace the perforated section


128


.




The body blank


10




V


in

FIG. 31

has six body flanges


40




a-f


, while the body blank


10




VI


in

FIG. 32

has four body flanges


40




a


,


40




c


,


40




d


, and


40




f


. Thus, in the assembled container, the body blank


10




V


will form C-shaped supports, while the body blank


10




VI


will form parallel supports.




In

FIG. 32

, notches


44


are removed from the first and second lateral edges


12


and


14


of the body blank


10




VI


at the intersection of the third and fourth panels


34


and


36


. As discussed previously, notches


44


provide holes in the assembled container to allow for the passage of liquid and air.





FIGS. 33 and 34

show alternate embodiments of side blanks


60




VII


and


60




VIII


. The side blanks


60




VII


and


60




VIII


include top and bottom flaps


64


and


66


hingedly connected to the central panels


62


along respective creases


68


and


70


. An access door


46


is located on side blank


60




VII


. Frangible sections


124


on the side blanks


60




VII


and


60




VIII


define positioning handles. The frangible section


124


on the side blank


60




VII


is located above the access door


46


.





FIGS. 35 and 36

show alternate embodiments of side blanks


60




IX


and


60




X


. The side blanks


60




IX


and


60




X


do not have bottom flaps


66


hingedly connected to the central panel


62


. In addition, the access door


46


in the body flange


60




IX


of

FIG. 35

is centrally located, while the access door


46


in the body flange


60




VII


of

FIG. 33

is closer to the edge of the central panel


62


. The position of the access door


46


may vary anywhere on the central panel


62


. In the preferred embodiment, the access door


46


is closer to the edge of the central panel


62


to limit the amount of liquid spilled onto the container


100




VI


when liquid is poured from the container


100




VI


. In all other respects, the side blanks


60




VII


and


60




VIII


are the same as the side blanks


60




VII


and


60




VIII


.





FIG. 37

shows an alternate embodiment of a side blank


60




XI


. The side blank


60




XI


eliminates the necessity of using two side blanks for each body blank to construct the container. The side blank


60




XI


has top flaps


64




a


and


64




b


, side panels


62




a


and


62




b


, and an end panel


122


. Both side panels


62




a


and


62




b


contain frangible sections

, shown in

FIG. 31

, and the body flanges

, and


60

, shown in

FIGS. 33 and 34

, respectively.

FIG. 38

shows the container


100




VI


in an open position,

FIG. 39

shows the container


100




VI


with both minor flaps


64


folded to a closed position,

FIG. 40

shows the container


10




VIII


, with one major flap


38


and both minor flaps


64


folded to a closed position, and

FIG. 41

shows the container


100




VI


with both major flaps


30


and


38


and minor flaps


64


folded to a closed position. As shown in

FIG. 41

, there is a full overlap of the first panel


30


over the fifth panel


38


to form a double sidewall. This provides a larger gluing surface to seal the container


VI


, and also enables more force to be applied to the container


VI


when sealing the containers


VI


.




Because the major flaps


30


and


38


and minor flaps


64


are oriented along the axis in which the containers


100


will be stacked, or stacking axis


206


, the containers


100


may be stacked on a pallet in an interlocking fashion (

FIG. 9

) instead of a columnar fashion (FIG.


10


). The interlocking stacking arrangement allows for stacking containers


100


cross-wise on top of containers


200


located on a layer below. Prior art containers such as the one shown in the '278 Patent, had insufficient structural support to be stacked in an interlocking fashion and had to be stacked in conformation with one another in a columnar stacking fashion shown in FIG.


10


. The interlocking stacking arrangement (

FIG. 9

) provides a more stable palletized load than the columnar stacking arrangement (FIG.


10


).




Further, because of the increased support gained through the orientation of the major flaps


30


and


38


and minor flaps


64


, an internal surface


210


along panels


32


and


36


and side blanks


60


of container


100


is a continuous, and smooth surface without the need of internal flanges


120


shown in the '278 Patent.




Because of the increased structural support of the container


100


, the container


100


may be used to ship single shipments using a common carrier such as U.P.S.




While the present container


100


has been described as generally rectangularly shaped, it is anticipated that the container could be constructed having various polygonal—shapes without departing from the present invention. Also, while the second end


104


of the rectangular sleeve


73


is closed by the cooperative folding of major and minor flaps, it is anticipated that a single sidewall could carry a flap that could close the container


100


or a separate cap could be used to close the container


100


without departing from the present invention.




While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention and the scope of protection is only limited by the scope of the accompanying claims.
