Abstract
A container which is formed from a one-piece blank so as to define a pair of side wall structures which support a fragile article in spaced relation from all external sides of the container. The side wall structures are folded so as to form generally tubular configurations which define respective elongate channels disposed in opposed relation with one another on opposite sides of the container. Opposite edges of the article are inserted into the respective channels so as to be spaced from the top, bottom and all sides of the container to provide protection against impact, for example during storage or transport.
Description




FIELD OF THE INVENTION




This invention relates to an improved shipping container which is assembled from a foldable blank and designed specifically for transporting fragile articles, such as framed pictures or the like.




BACKGROUND OF THE INVENTION




Many types of boxes or cartons are commercially employed for the storage and shipment of fragile articles, such as framed pictures, mirrors, or even sensitive electronic equipment, and are typically constructed of corrugated paperboard. These boxes are often provided therein with various kinds of cushioning materials and restraints in order to limit or prevent movement of the objects in the box to protect them from damage. It is also known to place separate corrugated inserts in corrugated board containers for the same purpose. However, these packaging techniques are less than satisfactory because several different manufacturing steps are required to provide the different components that make up the total container. Further, the shipment, storage and inventory of the different components is relatively difficult and the assembly operation is more complex and expensive than is desired.




Accordingly, shipping containers have been developed which are of a one-piece construction and are foldable from a corrugated blank to form a complete enclosed container. The folding of the blank forms internal cushioning structures which accommodate the article being stored or shipped. These types of containers support the article in spaced relation from the sides of the container so as to prevent injuries which can be caused by sidewardly directed impacts occurring during transport. For example, U.S. Pat. Nos. 3,790,065 and 3,791,571 each disclose one-piece blanks which are foldable into a cushioned package so as to define a cavity for a flat object, such as a book. The packages disclosed in these patents are foldable to form cushioning wall structures which support the ends of the object in inwardly-spaced relation from the external sides of the container to protect the object during shipping. However, these packages do not provide cushioning protection on all sides of the object, such as on the top and bottom thereof, which can lead to damage in the event of impacts.




Further, U.S. Pat. Nos. 5,145,070 (owned by the same assignee hereof) and 5,372,259 disclose containers, each formed from a one-piece blank which is foldable to define interior cushioning structures for supporting the object stored within the container in spaced relation from all external sides thereof. However, the cushioning structures are more complex than desired, such as requiring opposed foldable flaps for supporting one end of an object, and hence require increased assembly time and expense.




It is thus an object of the invention to provide an improved container formed from a one-piece blank which is foldable into a closed configuration and defines internal tubular support or cushioning structures at opposite ends of the container. The support structures in turn define therein elongate channels for receiving an end of the article being stored or transported and for restraining movement of the article to protect same from damage.




More specifically, the improved container, in accordance with one aspect of the invention, relates to a one-piece container constructed from a one-piece blank of corrugated material. The container includes a horizontally enlarged and generally planar bottom wall, and first and second elongate upright side walls folded upwardly from the bottom wall about fold lines which extend along respective side edges thereof. A horizontally enlarged top wall is integrally joined to one of the side walls and is pivotable with respect thereto between open and closed positions, and third and fourth elongate side wall structures are disposed in opposed spaced-apart relation with one another and extend transversely with respect to the first and second side walls. These side wall structures are each formed by a single flap integrally joined to the bottom wall and folded upwardly therefrom about a fold line which extends along one of the respective side edges thereof. Each of the flaps are foldable to define an outer wall which forms part of the external surface of the container and a plurality of support surfaces which together define a channel which opens generally sidewardly and inwardly. The channels of the opposed third and fourth side wall structures together define a pocket for receiving a generally plate-like article therein, and the support surfaces maintain the article in spaced relation from the top and bottom walls, the outer walls and the first and second side walls to prevent damage to the article during storage or transport thereof.




The invention also relates to a box including a generally planar bottom wall, first and second elongate and opposed side walls projecting generally upwardly from the bottom wall generally along one pair of side edges thereof, and third and fourth elongate and opposed end walls extending transversely relative to the first and second side walls and projecting generally upwardly from the bottom wall generally along another pair of side edges thereof. A top wall is disposed in generally parallel relation with the bottom wall and is spaced upwardly therefrom by the side and end walls. The box has a width dimension as defined between either pair of the opposed side and end walls which is significantly greater than a depth dimension as defined between the top and bottom walls so as to accommodate a generally planar, plate-like object therein. Further, a pair of elongate support structures are respectively positioned along the pair of opposed end walls in spaced-apart relation with one another, with each support structure defining a channel therein. The channels open inwardly towards one another for receiving opposite terminal edges of the object, and each support structure defines an air cushion which surrounds the edge of the object disposed within the respective channel so as space same inwardly of the top, bottom, side and end walls.











Other objects and purposes of the invention will be apparent to persons familiar with arrangements of this general type upon reading the following specification and inspecting the accompanying drawings.

DETAILED DESCRIPTION




Referring to

FIG. 1

, the present invention is directed to a flat blank


10


which in the illustrated embodiment is constructed of stiff double-faced corrugated cardboard having a corrugated interior layer bonded between a pair of flat facing layers, which layers are of all rather thin paper or fiberboard. The blank


10


is prepared using techniques which are conventional and well known in the box forming industry.




The blank


10


is foldable into the shape of a box or container


11


(

FIG. 3

) suitable for storing or transporting an object


11


A (shown in dotted lines in

FIGS. 2

,


4


and


6


-


8


), such as a framed or unframed picture, mirror, or other relatively fragile and plate-like article, which typically requires careful packing so as to avoid damage thereto. The container


11


includes a bottom part or base


12


and a top part


13


which are joined to one another by side walls


14


integrally connected to top and bottom parts


12


and


13


. Container


11


also includes an additional pair of side walls


15


which are oriented transversely relative to side walls


14


and are foldable to form protective tubular cushioning structures as discussed further below.




The blank


10


(

FIG. 1

) is a flat and generally planar, monolithic, one-piece element and defines a bottom wall


16


which forms part of bottom part


12


and has a generally rectangular shape. The bottom wall


16


includes a pair of generally parallel first side edges


20


and a pair of generally parallel second side edges


21


, the latter extending generally perpendicularly between the side edges


20


. All of the side edges


20


and


21


are defined by fold lines shown in dotted lines in FIG.


1


.




The top part


13


of the blank


10


is embodied by two flaps


23


, each of a generally rectangular configuration. Flaps


23


are each defined by a pair of generally parallel free side edges


24


, a longitudinal free side edge


25


which extends generally perpendicularly between the respective side edges


24


, and an inner side edge


26


defined by a fold line which joins the flap


23


to a respective side wall


14


.




Side walls


14


each include a pair of free side edges


30


, which extend generally perpendicularly between fold lines


21


and


26


and are aligned with (or formed from the same cut line as) the respective side edges


24


of top flap


23


.




With continued reference to

FIG. 1

, side walls


15


are embodied by first and second side wall parts


31


and


32


. The side wall parts


31


and


32


are joined to one another through a longitudinal fold line


33


which is generally parallel to the adjacent first side edge or fold line


20


of bottom wall


16


. A pair of reinforcing end flaps


34


are joined to respective opposite side edges or fold lines


35


of each side wall part


31


. Fold lines


35


are parallel to one another and extend perpendicularly between fold lines


20


and


33


. Each of the end flaps


34


are further defined by a pair of parallel longitudinal inner and outer free edges


36


. The inner free edge


36


of each flap


34


is disposed closely adjacent the respective side edges


30


and


24


of side wall


14


and top flap


23


and is formed by the same cut line. Each flap


34


additionally includes an outer free end edge


37


which extends perpendicularly between inner and outer edges


36


, and a pair of fold lines


38


parallel to and spaced inwardly from outer end edge


37


. Fold lines


38


divide the respective end flap


34


into three sections once folded, namely an inner section


39


, an intermediate section


40


, and an outer section


41


.




Each second side wall part


32


is defined by a free longitudinal side edge


42


, and a pair of parallel free side edges


43


which extend perpendicularly between fold line


33


and side edge


42


. Four parallel cut lines are oriented transversely between the fold line


33


and longitudinal side edge


42


of each second side wall part


32


. More specifically, a pair of central cut lines


44


parallel to free side edges


43


are oriented between a pair of outer cut lines


45


spaced inwardly from and parallel to side edges


43


. All of the cut lines


44


and


45


terminate short of both fold line


33


and the opposite free side edge


42


, and all terminate at equal distances outwardly from fold line


33


. The central cut lines


44


extend a further distance toward free side edge


42


than outer cut lines


45


, and cut lines


45


terminate at equal distances inwardly from edge


42


. A fold line


46


extends perpendicularly between these terminal ends of the respective central cut lines


44


and is spaced inwardly from and parallel to edge


42


. Additional fold lines


47


,


48


and


49


extend perpendicularly between central cut lines


44


. Fold lines


47


-


49


are spaced from and parallel to one another and to fold line


46


. Further, fold line


49


is spaced outwardly of the terminal ends of central cut lines


44


positioned adjacent fold line


33


, and fold lines


47


and


48


are located between inner and outer fold lines


49


and


46


. When side wall


15


is folded, the central cut lines


44


and the respective fold lines


46


-


49


together form a central cavity defining support


51


(

FIGS. 4 and 5

) as discussed below.




The respective terminal ends of each outer cut line


45


and the adjacent central cut line


44


located near fold line


33


are joined through a fold line


52


which extends perpendicularly between cut lines


44


and


45


and is parallel to and spaced outwardly from fold line


33


. Additional fold lines


53


,


54


and


55


extend between the respective pairs of central and outer cut lines


44


and


45


. Fold lines


53


-


55


are spaced from and parallel to one another and to fold line


52


. Further, fold lines


55


are longitudinally aligned with one another and with fold line


47


, as is the case with fold lines


53


and fold line


49


. Fold lines


52


are also longitudinally aligned with one another. When side wall


15


is folded, the outer cut lines


45


and the respective adjacent central cut lines


44


together with fold lines


52


-


55


cooperate to define endmost cavity defining supports


56


(FIGS.


4


and


5


). Supports


56


are located on opposite ends of central support


51


.




Each second side wall part


32


also includes a flap


57


located adjacent each outer cut line


45


. Each flap


57


is defined by an inner free edge


58


defined by the respective cut line


45


, and a pair of free side edges


59


defined by cut lines which are perpendicular to free edge


58


. Further, inner free side edge


59


of each flap


57


is generally longitudinally aligned with fold lines


53


and


49


, and outer free side edge


59


of each flap


57


is generally longitudinally aligned with fold lines


55


and


47


. A fold line


62


extends transversely between the respective free side edges


59


and is parallel to and spaced outwardly from the respective outer cut line


45


, and an additional pair of parallel fold lines


63


and


64


extend from opposite ends of fold line


62


to the respective free side edge


43


of second side wall part


32


and are perpendicular relative thereto. Fold line


62


separates the respective flap


57


from an end wall section


65


located outwardly thereof.




The blank


10


will normally be maintained in the flat condition illustrated by

FIG. 1

, which facilitates compact shipping and storage thereof. The blank


10


may be stamped or die cut from a large sheet of corrugated cardboard so as to result in the formation of a one-piece blank as illustrated by

FIG. 1

, and minor assembly steps are then required to permit enclosure of an object therein. These assembly steps will now be briefly described to ensure a complete understanding of the invention. Starting with the blank


10


in the flat condition shown in

FIG. 1

, each of the side walls


15


are folded to form a generally tubular configuration as follows. First side wall part


31


of one side wall


15


is folded upwardly about fold line


20


to vertically orient first side wall part


31


, and second side wall part


32


is thereafter folded inwardly about fold line


33


. Second side wall part


32


is then folded along longitudinally aligned fold lines


64


,


55


and


47


and also along longitudinally aligned fold lines


63


,


53


and


49


. Free edge


42


of second side wall part


32


is tucked against first side wall part


31


so as to lie along fold line


20


and place the respective side wall


15


in an elongate tubular configuration having a generally rectangular transverse cross-section. The folding of second side wall part


32


in the above manner results in the formation of longitudinal sections


32


A and


32


B of second side wall part


32


, which sections


32


A,


32


B are disposed in vertically-spaced juxtaposed relation with one another with lower section


32


B being positioned atop and flat against bottom wall


16


(FIG.


5


).




Thereafter, the respective flaps


57


located at opposite ends of the tubular side wall


15


are folded inwardly about the respective fold lines


62


so that flaps


57


are oriented generally perpendicular relative to the corresponding and now upright end wall sections


65


. The flaps


57


are now vertically oriented with the respective upper and lower edges thereof defined by cut lines


59


lying along the respective upper and lower longitudinal sections


32


A and


32


B of second side wall part


32


. Once flaps


57


are folded, the inwardly facing sides thereof define respective vertical object-supporting surfaces


66


for a purpose as discussed below.




While maintaining the tubular side wall


15


in a position so that the free edge


42


of second side wall part


32


lies along fold line


20


, the reinforcing end flaps


34


(which are presently vertically oriented due to the upright positioning of the corresponding first side wall part


31


) are each folded inwardly about the respective fold line


35


, and then inwardly along fold lines


38


, and the entire flap


34


is pushed into the adjacent open end of the tubular side wall


15


so that the inner section


39


of flap


34


lies against the inwardly facing surface of first side wall part


31


, the outer section


41


lies against the inwardly facing surface of the adjacent end wall section


65


, and the intermediate section


40


lies against the outwardly facing surface of flap


57


opposite surface


66


(FIGS.


5


and


6


). The upper and lower free edges


36


of the now vertically oriented intermediate section


40


lie along the respective upper and lower longitudinal sections


32


A and


32


B of second side wall part


32


. In the illustrated embodiment, the reinforcing end flaps


34


completely close off the respective ends of tubular side wall


15


and assist in maintaining same in its folded tubular configuration.




The tubular side wall


15


is then folded to define cavity defining supports


51


and


56


as follows. Each of the endmost cavity defining supports


56


are formed by applying pressure to the second side wall part


32


in a direction generally toward bottom wall


16


along the respective fold line


53


which causes second side wall part


32


to crease along fold lines


52


and


54


and “pop” inwardly, resulting in an L-shaped configuration as shown in

FIGS. 5 and 7

. This L-shaped configuration of support


56


defines respective horizontal and vertical and generally planar support surfaces


70


and


71


. Horizontal support surface


70


is spaced upwardly from bottom wall


16


by a vertically extending bottom wall


72


of support


56


defined between fold lines


54


and


55


. Central cavity defining support


51


is formed by applying upward pressure to second side wall part


32


along fold line


47


, causing side wall part


32


to crease along fold lines


46


and


48


, resulting in an inverted L-shaped configuration (see

FIGS. 5 and 8

) defining horizontal and vertical planar support surfaces


73


and


74


. Horizontal support surface


73


is spaced downwardly from section


32


A by a vertically extending upper wall


74


A of support


51


defined between fold lines


48


and


49


. Further, horizontal support surface


73


of central support


51


is parallel to and spaced upwardly from the respective horizontal support surfaces


70


of endmost supports


56


and is also horizontally offset relative thereto. As shown in FIGS.


4


and


6


-


8


, the end surfaces


66


of flaps


57


along with support surfaces


70


and


71


of endmost supports


56


, and along with support surfaces


73


and


74


of central support


51


, define an elongate sidewardly opening channel


75


for receiving the edge of object


11


A (shown in dotted lines in

FIGS. 2

,


4


and


6


-


8


), such as a framed or unframed picture, or other fragile and generally flat object.




With one side wall


15


folded as described above, a terminal edge of the object or picture


11


A is then inserted into channel


75


while the opposite side wall


15


is folded in the same manner as described above so as to form a tubular configuration defining a pair of endmost cavity defining supports


56


and a central cavity defining support


51


disposed therebetween. During folding of the second or opposite side wall


15


, it may be necessary to position the object


11


A in an angled or tilted orientation relative to bottom wall


16


so as not to interfere with the folding of portions of the second side wall


15


, and then as the side wall


15


is folded to define the supports


51


and


56


, the raised terminal edge of the object


11


A (i.e. the terminal edge of the object


11


A opposite the edge inserted within channel


75


) can then be pivoted or lowered into the second channel


75


. During this insertion of the object edge into the second channel


75


, it may be necessary to slightly tilt or pivot the corresponding second tubular side wall


15


upwardly about the respective fold line


20


so as to allow easier insertion of the object edge into channel


75


.




After assembly of side walls


15


as discussed above, the channels


75


defined thereby open sidewardly and inwardly toward one another so as to define a generally horizontally oriented and rectangular pocket or cavity within container


11


for receiving the object


11


A.




With the opposite terminal edges of the object or picture


11


A inserted into the respective opposed channels


75


as discussed above, the object


11


A is supported in upwardly spaced relation from bottom wall


16


via the horizontal support surfaces


70


of the respective endmost supports


56


. Side walls


14


are then folded upwardly about the respective fold lines


21


and then inwardly about the respective fold lines


26


, so that the free side edges


25


of the respective top wall flaps


23


are disposed in opposed relation with one another. Adhesive tape or other fasteners can then be applied to the seam defined between edges


25


so as to completely enclose the object


11


A within the container or box


11


. It will be appreciated that top part


13


may be of a single-flap construction joined to one of side walls


14


, if desirable. Further, the top part


13


may be provided with integral tabs or other locking features for closing the container


11


so as to avoid the necessity for adhesive tape.




It will be appreciated that while the above-described sequence of assembly steps is the preferred assembly sequence, same may be modified, for example, depending upon the particular object being packaged and also upon the configuration of the work area where the container is assembled. In addition, instead of inserting one edge of the object


11


A into channel


75


of a folded side wall


15


and then folding the opposite side wall


15


as discussed above, it is possible to fold both side walls


15


into their tubular configurations and to define the respective supports


51


and


56


, and then pivot or tilt each of the tubular side walls


15


slightly upwardly about their respective fold lines


20


to allow insertion of the object edges within the respective channels


75


. Once the object


11


A is positioned within the channels


75


, the tubular side walls


15


are then pivoted downwardly so as to lie along bottom wall


16


.




The configuration of the respective side walls


15


as disclosed herein supports the object


11


A centrally within the container


11


in spaced relation from all external sides thereof, which provides an air space along all sides of the object


11


A to cushion against impact loads. More specifically, the end surfaces


66


of the respective flaps


57


space the object horizontally inwardly from the respective upright side walls


14


, the vertical surfaces


71


and


74


of supports


56


and


51


space the object horizontally inwardly from the respective upright side walls


31


, the horizontal lower surfaces


70


of the endmost supports


56


space the object upwardly from bottom wall


16


, and horizontal surface


73


of central support


51


spaces the object downwardly from top wall flaps


23


.




The construction of the container


11


from a one-piece blank is advantageous as same eliminates the need for separate inserts or fillers, such as bubble wrap or plastic foam inserts. However, if desirable or necessary, for example to increase load capacity, the open cavities defined within the side walls


15


can be filled with foam or other cushioning materials. Further, the opposed cavity defining supports


51


and


56


are each formed from a single side wall


15


or flap structure, as compared to conventional packages which require folding of multiple flaps to form the cushioning arrangement which supports one side of the article.




While the formation of the container


11


from a one-piece blank is advantageous as discussed above, it is also possible to manufacture the tubular side walls


15


as separate components which can be filled with foam and installed on the edges of heavy articles, such as doors, windows, etc. The entire article can then be enclosed within a separate box or wrapper.




It will be appreciated that while the reinforcing flaps


34


help to hold the respective side walls


15


in the tubular configuration and also provide same with added rigidity, the flaps


57


may alone be sufficient to reinforce side wall


15


while simultaneously forming the object-supporting end surfaces


66


for spacing the object inwardly of the respective side wall


14


.




It will also be appreciated that the side walls


15


, once folded into the tubular configuration as discussed above, will retain their folded configuration, particularly after the object


11


A is inserted into the container


11


. However, it may be desirable to additionally secure side walls


15


(once folded) relative to bottom wall


16


with adhesive tape.




It will be understood that terms such as “horizontal” and “vertical” herein are used for convenience to describe the container when oriented horizontally as in the drawings. However, it will be appreciated that the container may be assembled in any orientation convenient to the assembler. Further, once the object


11


A is enclosed within the container, same may be stored or transported with either of the bottom part


12


or top part


13


disposed uppermost.




Although a particular preferred embodiment of the invention has been disclosed in detail for illustrative purposes, it will be recognized that variations or modifications of the disclosed apparatus, including the rearrangement of parts, lie within the scope of the present invention.
