## Title
Corrugated hanging dispenser

## Abstract

A dispensing container (10, 110) for fluent material, which container is intended to he hung vertically from a support, such as a hook, is provided. The dispensing container has a tubular body, with a bottom dispensing region that is configured to promote the collection of the fluent material and guidance of the fluent material toward the inlet aperture of a dispensing nozzle (50) that is received in the side (30, 130) of the bottom dispensing region. The dispensing container (10, 110) is preferably fabricated from corrugated paperboard or similar material, and is preferably configured to serve as the shipping container for the fluent material as well, so as to reduce or eliminate the need for a further outer shipping container. The fluent material may be contained within a separate liner structure, within the surrounding tubular body, in a “bag-in-box” type of container arrangement.

## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is entitled to the benefit of, and claims priority to, PCT International Patent Application No. PCT/US2003/00501 filed on Jan. 9, 2003, and titled “Corrugated Hanging Dispenser,” which is a continuation-in-part of U.S. Pat. No. 6,443,329, issued Sep. 3, 2002, and titled “Corrugated Hanging Dispenser,” both of which are hereby incorporated by reference in their entirety.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is directed to cartons fabricated from paper, paperboard and/or corrugated paperboard. In particular, the present invention is directed to cartons that are configured to be hung vertically to serve as a dispenser for fluent materials.
2. Prior Art
Hanging dispensers are known, for dispensing fluent materials such as liquid or finely powdered soap, detergent and the like. Such prior art dispensing devices are typically fabricated from plastic, glass and/or metal. In addition, such prior art devices are typically permanently mounted devices, which to remain useful, must be refilled when the existing supply of fluent material has been exhausted. Such refilling may require filling a storage portion of the device from a larger container of material (e.g., by pouring from one to the other). Such a process can be time consuming and lead to spillage and waste. Alternatively, some prior art dispensing devices employ interchangeable and/or replaceable canisters or cartridges.
It would be desirable to replace such permanently installed dispensing devices, with disposable devices that may simply be discarded, upon exhaustion of the contents.
It would also be desirable to provide a disposable hanging dispensing device that can be readily recycled, either in whole or in part.
It would further be desirable to provide disposable hanging dispensing devices that can also serve the dual purpose of being the shipping container for the fluent material, which is to be dispensed, without requiring a separate container for the fluent material.
These and other desirable characteristics of the present invention will become apparent in view of the present specification, including claims, and drawings.

DETAILED DESCRIPTION OF THE DRAWINGS
While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will be described herein in detail, a specific embodiment, with the understanding that the present invention is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiment illustrated.
Dispensing container 10 is illustrated in a first preferred embodiment, in FIGS. 1-6. Dispensing container 10 is shown, in its articulated, assembled form in FIGS. 1-3, being perspective, front and left side views respectively.
FIG. 4 is a plan view of a blank 12 for forming dispensing container 10, with the “inside” surface of blank 12 facing the observer. In FIG. 4, as in the other figures, unless otherwise noted, the usual convention is observed that solid lines on the interior of a figure represent cuts, edges or points of inflection (like a ridge, crease or inwardly or outwardly projecting gusset), and broken or dashed lines indicate folds, score lines or other lines of weakness.
Blank 12 is preferably fabricated from corrugated paperboard, although other similar fiber based materials may be employed. Blank 12 may also be coated, impregnated or laminated, on the inside, outside or both, with materials that may provide moisture resistance, substantially complete liquid barrier characteristics, vapor barrier characteristics or other handling or performance characteristics, as may be desired. Preferably, any such coatings, impregnations or laminations will be made of materials which themselves permit recycling of the entire container 10 (minus nozzle 50 as described herein) without special pre-treatment. In a preferred embodiment of the invention, the flutes are oriented to run vertically in most of the finished container, particularly the large front, left, right and rear side walls, to provide improved strength in the side walls to resist elongation of the side walls under load, especially if the container is to be subjected to a moist or humid environment.
Dispensing container 10 has a front wall 14, left side wall 16, right side wall 18, rear wall 20, top wall 22, hanging flap 24, top closure flaps 26 and 28, bottom front wall 30, bottom closure flap 32, bottom rear wall 34, left bottom panel 36 with adjacent gusset flaps 38 and 40, right bottom panel 42 with adjacent gusset flaps 44 and 46, and container closure flap 48.
Dispensing container 10 typically will also include an openable and securely reclosable dispensing nozzle 50, which may have any particular shape and configuration as may be desired or required by the characteristics of the particular fluent material being dispensed. The fluent material intended to be dispensed may be further contained within a liner bag (not shown), the bottom end of which may be connected to an inner aperture (not shown) of nozzle 50. This will create a “bag-in-box” type of container. Alternatively, the fluent material may not be further confined within a liner bag, and so the inner aperture of nozzle 50 may simply open onto the interior of dispensing container 10. Such dispensing nozzles are well known, and as such, the specific details of the construction of nozzle 50 need not be addressed for the principles of the present invention to be understood by one of ordinary skill in the art having the present disclosure before them. Accordingly, such details of nozzle 50 are generally omitted from the present application.
However, regardless of the specific construction of nozzle 50, it will typically have two axially spaced surrounding retaining flanges, such as outer flange 52 which bears against the outer surface of bottom front panel 30, and a corresponding inner flange (not shown) that will bear against the inner surface of bottom front panel 30, so that nozzle 50 will be securely held in place, to facilitate operation of the nozzle. In order to facilitate installation of nozzle 50, nozzle restraining flap 54, which is pivotable about fold line 56 is provided in bottom front panel 30, adjacent die cut aperture 58. Die cut aperture 58 is preferably configured to have a shape, which conforms to the outer periphery of that portion of nozzle 50 between the inner and outer axially spaced retaining flanges. In a typical nozzle 50, that portion of nozzle 50 between the retaining flanges is circular, so aperture 58, in a typical preferred embodiment, will likewise be circular, and have a diameter slightly greater than the diameter of the Is portion of nozzle 50 being surrounded.
Hanging flap 24 includes a rigid portion 60 (emanating from the upper portion of rear wall 20) from which folding portion 62 emanates. Rigid portion 60 includes hanging apertures 64, 66. Folding portion 62 includes hanging apertures 68, 70, which, in FIG. 4 are inverted, so that when folding portion 62 is folded over, apertures 68, 70 overlie and align with apertures 64, 66. Folding portion 62 further includes locking aperture 72, the function of which will be described later.
When dispensing container 10 is to be formed, front wall 14, left and right side walls 16 and 18 and rear wall 20 are folded about their respective longitudinal fold lines to form a rectangular tubular body. Closure flap 48 is folded to the inside of right side wall 18 and bottom rear wall 34, and affixed thereto, preferably with any suitable adhesive material.
Next, formation of the bottom dispensing portion of the tubular body is accomplished, by pushing right and left bottom panels 36, 42, inwardly, causing, in turn, gusset panels 38, 40 and 44, 46 to be pushed inwardly. This movement, in turn, causes the bottom front wall 30 and bottom rear wall 34, to incline toward one another, to form an inverted gable, as shown in FIGS. 1 and 3. Finally, bottom closure flap 32 is folded over to be juxtaposed to the outside surface of bottom rear wall 34 and suitably permanently affixed thereto, such as by a suitable adhesive.
Preferably, the dimensions, proportions and aspect ratios of the various bottom walls and panels are selected, so that when the inward articulation of all the panels is completed, gusset panels 38 and 46 are substantially parallel and juxtaposed to bottom front wall 30, and gusset panels 40 and 44 are substantially parallel and juxtaposed to bottom rear wall 34. In addition, when articulation is completed, the interior configuration of bottom front wall 30, bottom rear wall 34, left bottom panel 36 and right bottom panel 42 form an inverted four-sided pyramid, with all sides sloping to a central bottom point. This inverted pyramidal configuration of the interior bottom is useful in that it promotes the concentration and guidance of the fluent material to a small localized area. Preferably, nozzle aperture 58 is positioned within bottom front panel 30 close to the “point” of the inverted pyramidal shape, so that the fluent material being dispensed is prompted toward the inlet of nozzle 50. In this manner, wastage of fluent material is minimized.
All of the creases and joints in the fully articulated dispensing container 10 may be rendered substantially siftproof with respect to particulate material and, depending upon whether blank 12 has been coated or laminated as described previously, leakproof with respect to liquid or slurry materials.
Folding portion 62 is then folded over, to the inside of rigid portion 60, and affixed thereto. Folding portion 62 provides container 10 with a double-thickness of material in the regions of apertures 64,66, 68, 70, which might otherwise be susceptible to tear initiation and propagation by narrow-diameter metal hanging hooks or other similar hanging devices.
Dispensing container 10 may then be filled with the fluent material, whether in a further liner bag or not. If a liner bag is provided, as in a “bag-in-box” type container, typically, nozzle 50 will be already permanently affixed to the bottom of the bag. To install nozzle 50, nozzle restraining flap 54 will be pushed out, the liner bag with nozzle 50 attached, is inserted into dispensing container 10, and nozzle 50 is pushed through aperture 58, so that the inner and outer restraining flanges capture the thickness of bottom front wall 30. Nozzle restraining flap 54 is then tucked back into place, with its bottom periphery captured between the inner and outer retaining flanges of nozzle 50. If no liner bag is used, then nozzle 50 may be installed from the inside out or outside in, as desired or expedient.
Closure of dispensing container 10 is accomplished by folding over top closure flaps 26, 28, and then folding over top wall 22. Top wall closure flap 74 is folded perpendicular to top wall 22. Closure tab 76 is die cut into top wall closure flap 74, so that closure tab 76 projects when top wall closure flap 74 is folded over. Closure tab 76 is inserted between the rear edges of top closure flaps 26, 28, and the inner facing surface of folding portion 62, and closure tab 76 is insertingly received into closure aperture 72.
When the contents of dispensing container 10 have been exhausted, nozzle 50 (with liner bag, if present) may be removed and separately recycled (if fabricated from suitably recyclable materials), and the remaining container 10 may be crushed or otherwise reduced, and recycled using ordinary recycling techniques.
In preferred embodiments of the invention, containers 10 will have rectangular cross-sections (when seen from above) as is the case with the embodiment of FIGS. 1-4, so that containers 10 can: be filled with fluent material, and stacked on their sides (such as on pallets), without the need for additional packaging, apart from plastic shrink wrap or other known techniques for restraining unboxed items on shipping pallets or flats. In this manner, container 10 serves not only as a dispenser, but also as the shipping container for the fluent material to be dispensed.
The dispensing container of the embodiment of FIGS. 1-4 is provided with a rectangular cross-sectional configuration, when viewed from above or below. However, it is to be understood that other polygonal cross-sectional configurations may be employed, without departing from the scope of the present invention, as they may be configured to provide a bottom dispensing region that is in the shape of an inverted pyramid, to come to a point at the bottom, while still resulting from an economically shaped and relatively simple blank configuration. For example, a dispensing container having a tubular body with only three sides (resulting in a triangular cross-section when viewed from above) may be readily formed, resulting in a bottom dispensing region in the shape of a three-sided pyramid. Other cross-sectional configurations may be employed, although increasing the number of sides may increase the complexity of the blank and method of articulation of the blank into a functional container, possibly increasing the cost of the container. Fewer than three side walls of course, cannot define a volume, unless one of the side walls is curved and not planar.
The sequence of panels formed in blank 10 as shown in FIG. 4, with the right side wall, front wall, left side wall, and rear wall, proceeding from left to right, with their corresponding top and bottom closure panels and/or hanging flap panels, represents a preferred embodiment of the invention. However, it is to be understood that the illustrated sequence may be varied (i.e., indexed) by one of ordinary skill in the art, having the present disclosure before them, without substantially altering the resultant dispensing container configuration (and thus without departing from the scope of the present invention), as this would simply result in the shifting of the manufacturer's joint from one longitudinally (i.e., vertically) extending corner of the finally erected container to the next.
FIGS. 5 and 6 provide additional views of the dispenser of the embodiment of FIGS. 1-4, minus the dispensing nozzle.
Dispensing container 110 is illustrated in an alternative preferred embodiment, in FIGS. 7-10. Dispensing container 110 is shown, in its articulated, assembled form in FIGS. 8-10.
FIG. 7 is a plan view of a blank 112 for forming dispensing container 110, with the “inside” surface of blank 112 facing the observer. In FIGS. 7-10, as in the other figures, unless otherwise noted, the usual convention is observed that solid lines on the interior of a figure represent cuts, edges or points of inflection (like a ridge, crease or inwardly or outwardly projecting gusset), and broken or dashed lines indicate folds, score lines or other lines of weakness.
Blank 112 is preferably fabricated from corrugated paperboard, although other similar fiber based materials may be employed. Blank 112 may also be coated, impregnated or laminated, on the inside, outside or both, with materials that may provide moisture resistance, substantially complete liquid barrier characteristics, vapor barrier characteristics or other handling or performance characteristics, as may be desired. Preferably, any such coatings, impregnations or laminations will be made of materials which themselves permit recycling of the entire container 110 (minus the dispensing nozzle, not shown, but which may be identical to nozzle 50 as described herein with respect to the embodiment of FIGS. 1-6) without special pre-treatment. In the embodiment of FIGS. 7-10, the if executed in corrugated material, the corrugations may be selected to run horizontally in the fully erected container, or they may be selected to run vertically.
Dispensing container 110 has a front wall 114, left side wall 116, right side wall 118, rear wall 120, major (outside) top closure flaps 122 and 124, minor (inside) top closure flaps 126 and 128, bottom front wall 130, bottom closure flap (glue flange) 132, bottom rear wall 134, left bottom panel 136 with adjacent gusset flaps 138 and 140, right bottom panel 142 with adjacent gusset flaps 144 and 146, and container closure (or glue) flap 148, which has a diagonal cut 150, to accommodate the bending of flap 148 when the gable bottom is formed.
Dispensing container 110 typically will also include an openable and securely reclosable dispensing nozzle (not shown), which as in the embodiment of FIGS. 1-6, may have any particular shape and configuration as may be desired or required by the characteristics of the particular fluent material being dispensed. The fluent material intended to be dispensed may be further contained within a liner bag (not shown), the bottom end of which may be connected to an inner aperture (not shown) of the nozzle. This will create a “bag-in-box” type of container. Alternatively, the fluent material may not be further confined within a liner bag, and so the inner aperture of the nozzle may simply open onto the interior of dispensing container 110. Such dispensing nozzles are well known, and as such, the specific details of the construction of the nozzle need not be addressed for the principles of the present invention to be understood by one of ordinary skill in the art having the present disclosure before them. Accordingly, such details of the dispensing nozzle are generally omitted from the present application.
However, regardless of the specific construction of the dispensing nozzle, it will typically have two axially spaced surrounding retaining flanges, such as an outer flange (like flange 52 in the embodiment of FIGS. 1-6) which bears against the outer surface of bottom front panel 130, and a corresponding inner flange (not shown) that will bear against the inner surface of bottom front panel 130, so that the nozzle will be securely held in place, to facilitate operation of the nozzle. In order to facilitate installation of the nozzle, nozzle restraining flap 154, which is pivotable about fold line 156 is provided in bottom front panel 130, adjacent die cut aperture 158. Die cut aperture 158 is preferably configured to have a shape, which conforms to the outer periphery of that portion of the nozzle between the inner and outer axially spaced retaining flanges. In a typical nozzle, that portion of the nozzle between the retaining flanges is circular, so aperture 158, in a typical preferred embodiment, will likewise be circular, and have a diameter slightly greater than the diameter of the portion of the nozzle being surrounded.
Instead of the hanging flap 24 used in the embodiment of FIGS. 1-6, hanging dispenser apparatus 110 is suspended via hanging apertures 164, 166 which are disposed in a upper region of rear wall 120.
When dispensing container 110 is to be formed, front wall 114, left and right side walls 116 and 118 and rear wall 120 are folded about their respective longitudinal fold lines to form a rectangular tubular body. Closure flap (or glue lap) 148 is folded to the inside of right side wall 118 and bottom rear wall 134, and affixed thereto, preferably with any suitable adhesive material.
Next, formation of the bottom dispensing portion of the tubular body is accomplished, by pushing right and left bottom panels 136, 142, inwardly, causing, in turn, gusset panels 138, 140 and 144, 146 to be pushed inwardly. This movement, in turn, causes the bottom front wall 130 and bottom rear wall 134, to incline toward one another, to form an inverted gable, as shown in FIGS. 9 and 10. Finally, bottom closure flap (glue flap) 132 is folded over to be juxtaposed to the outside surface of bottom rear wall 134 and suitably permanently affixed thereto, such as by a suitable adhesive.
Preferably, the dimensions, proportions and aspect ratios of the various bottom walls and panels are selected, so that when the inward articulation of all the panels is completed, gusset panels 138 and 146 are substantially parallel and juxtaposed to bottom front wall 130, and gusset panels 140 and 144 are substantially parallel and juxtaposed to bottom rear wall 134. In addition, when articulation is completed, the interior configuration of bottom front wall 130, bottom rear wall 134, left bottom panel 136 and right bottom panel 142 form an inverted four-sided pyramid, with all sides sloping to a central bottom point. This inverted pyramidal configuration of the interior bottom is useful in that it promotes the concentration and guidance of the fluent material to a small localized area. Preferably, nozzle aperture 158 is positioned within bottom front panel 130 close to the “point” of the inverted pyramidal shape, so that the fluent material being dispensed is prompted toward the inlet of the dispensing nozzle (not shown). In this manner, wastage of fluent material is minimized.
All of the creases and joints in the fully articulated dispensing container 110 may be rendered substantially siftproof with respect to particulate material and, depending upon whether blank 112 has been coated or laminated as described previously, leakproof with respect to liquid or slurry materials.
Dispensing container 110 may then be filled with the fluent material, whether in a further liner bag or not. If a liner bag is provided, as in a “bag-in-box” type container, typically, the dispensing nozzle (not shown) will be already permanently affixed to the bottom of the bag. To install the dispensing nozzle, nozzle restraining flap 154 will be pushed out, the liner bag with nozzle attached is inserted into dispensing container 110, and the nozzle is pushed through aperture 158, so that the inner and outer restraining flanges capture the thickness of bottom front wall 130. Nozzle restraining flap 154 is then tucked back into place, with its bottom periphery captured between the inner and outer retaining flanges of the dispensing nozzle. If no liner bag is used, then the nozzle may be installed from the inside out or outside in, as desired or expedient.
Closure of dispensing container 110 is accomplished by folding over minor top closure flaps 126, 128, and then folding over and gluing major top closure flaps 122, 124.
When the contents of dispensing container 110 have been exhausted, the nozzle (with liner bag, if present) may be removed and separately recycled (if fabricated from suitably recyclable materials), and the remaining container 110 may be crushed or otherwise reduced, and recycled using ordinary recycling techniques.
In preferred embodiments of the invention, containers 110 will have rectangular cross-sections (when seen from above) as is the case with the embodiment of FIGS. 1-6, so that containers 110 can be filled with fluent material, and stacked on their sides (such as on pallets), without the need for additional packaging, apart from plastic shrink wrap or other known techniques for restraining unboxed items on shipping pallets or flats. In this manner, container 110 serves not only as a dispenser, but also as the shipping container for the fluent material to be dispensed.
The dispensing container of the embodiment of FIGS. 7-10 is provided with a rectangular cross-sectional configuration, when viewed from above or below. However, it is to be understood that other polygonal cross-sectional configurations may be employed, without departing from the scope of the present invention, as they may be configured to provide a bottom dispensing region that is in the shape of an inverted pyramid, to come to a point at the bottom, while still resulting from an economically shaped and relatively simple blank configuration. For example, a dispensing container having a tubular body with only three sides (resulting in a triangular cross-section when viewed from above) may be readily formed, resulting in a bottom dispensing region in the shape of a three-sided pyramid. Other cross-sectional configurations may be employed, although increasing the number of sides may increase the complexity of the blank and method of articulation of the blank into a functional container, possibly increasing the cost of the container. Fewer than three side walls of course, cannot define a volume, unless one of the side walls is curved and not planar.
The sequence of panels formed in blank 110 as shown in FIG. 7, with the right side wall, front wall, left side wall, and rear wall, proceeding from right to left, with their corresponding top and bottom closure panels, represents a preferred embodiment of the invention. However, it is to be understood that the illustrated sequence may be varied (i.e., indexed) by one of ordinary skill in the art, having the present disclosure before them, without substantially altering the resultant dispensing container configuration (and thus without departing from the scope of the present invention), as this would simply result in the shifting of the manufacturer's joint from one longitudinally (i.e., vertically) extending corner of the finally erected container to the next.
The foregoing description and drawings merely explain and illustrate the invention, and the invention is not limited except insofar as the appended claims are so limited, as those skilled in the art who have the disclosure before them will be able to make modifications and variations therein without departing from the scope of the invention.

## Claims

1. A dispensing container operably configured to be suspended from a support for facilitating dispensing of fluent material, the dispensing container comprising:
a substantially tubular body defining and enclosing a cavity of the dispensing container, the cavity defining a fluent material containment volume, the tubular body comprising:
a closure structure disposed proximate an opening in an upper portion of the tubular body; and
a bottom dispensing region comprising an internal cross-sectional area that decreases from an upper portion of the bottom dispensing region to a lower portion of the bottom dispensing region for collecting and guiding fluent material contained therein toward a localized area;

a nozzle receiving structure operably disposed in the bottom dispensing region for securely but releasably, restrainedly receiving a dispensing nozzle so that an inlet aperture of the dispensing nozzle received by the nozzle receiving structure opens onto the cavity at the bottom dispensing region; and
a hanging support structure defined through the tubular body to enable the dispensing container to be removably hung upon and supported by a projecting support member, wherein the hanging support structure comprises at least one hanging aperture defined in a wall of the tubular body, the at least one hanging aperture providing access to the cavity,
the substantially tubular body being fabricated from at least one of paper, paperboard, and corrugated paperboard.

2. A dispensing container according to claim 1 wherein the hanging support structure comprises a pair of hanging apertures defined through a wall of the tubular body, a first one of the pair of hanging apertures being spaced from a second one of the pair of hanging apertures along a width of the wall of the tubular body.

3. A blank for forming a dispensing container that is operably configured to be suspended from a support for facilitating dispensing of fluent material, the blank comprising:
a plurality of at least three substantially rectangular side wall panels, operably connected to one another along longitudinally extending lines of weakness extending between adjacent ones of the side wall panels, the lines of weakness enabling the side wall panels to be articulated with respect to one another to form, in part, a substantially tubular body defining a cavity of the dispensing container and comprising an opening in an upper portion of the substantially tubular body;
at least one top closure panel operably connected to at least one of the side wall panels along a top peripheral region thereof, the at least one top closure panel providing a closure structure proximate the opening formed in the upper portion of a the substantially tubular body formed upon articulation of the plurality of substantially rectangular side wall panels;
a plurality of bottom panels operably connected to at least three side walls along bottom peripheral regions thereof; the plurality of bottom panels are operably configured, upon articulation of the blank into the dispensing container, to enable the formation of a bottom dispensing region comprising an internal cross-sectional area that decreases from an upper portion of the bottom dispensing region to a lower portion of the bottom dispensing region for collecting and guiding fluent material contained therein toward a localized area;
the plurality of at least three side wall panels, the at least one top closure panel, and the plurality of bottom panels collectively forming the substantially tubular body and defining and enclosing, upon articulation of the blank into a container, the cavity that defines a fluent material containment volume;
a nozzle receiving structure operably disposed in at least one of the bottom panels, the nozzle receivigg structure securely but releasably, restrainedly receiving a dispensing nozzle, upon articulation of the blank into the dispensing container, so that an inlet aperture of the dispensing nozzle received by the nozzle receiving structure opens onto the cavity at the bottom dispensing region; and
at least one hanging aperture defined through one of the at least three substantially rectangular side wall panels, wherein, upon articulation of the blank into the dispensing container, the at least one hanging aperture enables access to the cavity;
the blank being fabricated from at least one of the following materials: paper, paperboard, and corrugated paperboard.
