DETAILED DESCRIPTION OF THE DISCLOSURE

(18) While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and described herein in detail a specific embodiment with the understanding that the present disclosure is to be considered as an exemplification and is not intended to be limited to the embodiment illustrated.

(19) It will be understood that like or analogous elements and/or components, referred to herein, may be identified throughout the drawings by like reference characters. In addition, it will be understood that the drawings are merely schematic representations of the invention, and some of the components may have been distorted from actual scale for purposes of pictorial clarity.

(20) Referring now to the drawings and in particular to FIGS. 1 through 8, bag in box packaging 10 is shown in FIG. 1 as comprising outer carton 12, inner bag 16 (FIG. 15), and tap 18. The outer carton 12 is shown as comprising outer walls 17 and inner spout retaining member 19. Generally, the outer carton 12 is formed from a corrugated paperboard material. Of course, other materials, such as non-corrugated paperboard as well as different polymer sheeting materials (corrugated and non-corrugated) are likewise contemplated. Additionally, other formed materials that can be formed into such configurations are contemplated for use.

(21) With additional reference to FIG. 13 (which is a slightly different embodiment), the outer walls 17 form a generally rectangular cubic configuration, although other configurations are likewise contemplated (such as, for example, square configurations as well as configurations that are polygonal, trapezoidal, etc.). In the configuration shown in FIG. 1, the outer walls 17 include front wall 20, back wall 22, first sidewall 24, second sidewall 26 top wall structure 28 and bottom wall structure 29. The walls abut each other at edges, and the edges meet at corners. It will be understood that the first and second sidewalls span between the front wall and the back wall on opposing sides of each other. The top wall structure closes the upper portion of the carton with the bottom wall structure forming the lower portion of the carton. It will be understood that the outer walls 17 are formed from a blank which has the front, back and side panels being sequentially positioned in an adjacent side by side manner, defining the four panels, separated by fold lines. A tab may extend from the first panel which mates with the fourth panel to form the four walls in a generally rectangular configuration.

(22) The top wall structure 28 is generally formed from four separate panels, each of which extends from one of the sidewalls or one of the front or back walls. The top wall structure 28 includes front flap 30 which extends from the front wall 20, back flap 31 which extends from the back wall 22, first side flap 32 which extends from the first sidewall 24, and second side flap 33 that extends from the second sidewall 26. Similarly, the bottom wall structure 29 includes front flap 34 extending from the front wall 20, back flap 35 extending from the back wall 22, first side flap 36 extending from the first sidewall 24, and second side flap 37 extending from the second sidewall 26.

(23) The inner spout retaining member 19 spans between two adjacent walls so as to be spaced apart from the edge joining the two corners. Typically, as well, the inner spout retaining member 19 is perpendicular to the top and the bottom panel structures, although the same is not required. The first panel 50 spans diagonally from the first side wall 24 to the front wall 20 obliquely relative to each wall and spaced apart from a side edge joining the front wall to the first sidewall 24, to, in turn, define a generally trianglular cross-sectional configuration therebetween. In the configuration shown, the triangular cross-section defines a generally right triangle with the remaining angles being equal to each other. Such a configuration centers the first panel 50 such that the spout can be directed at the side edge between the front wall and the first sidewall.

(24) The inner spout retaining member 19 includes first panel 50, sidewall engaging panel 52 and front wall engaging panel 53. A portion of the bottom wall structure may include a bottom encapsulating panel 56. The inner spout retaining member 19 can be formed from a blank separate from the outer carton, or as is shown in FIG. 13, along with the remainder of the blank. It is generally, therefore, formed from the same material as the remainder of the outer carton.

(25) With reference to FIGS. 2, 3, 5, 6 7 and 13, the sidewall engaging panel 52 overlies and is glued to the first sidewall 24 about the outside surface of the inner spout retaining member. On the opposing side, the front wall engaging panel 53 overlies and is glued to the front wall about the outside surface of the front wall engaging panel. Such an assembly defines a pocket that is, in the example shown, generally of a triangular cross-sectional configuration.

(26) The first panel 50 further includes a spout receiving slot 60 at the lower end thereof which is configured to engage a spout of a bag (or a tap coupled to the spout of a bag). Generally, the spout receiving slot 60 is centrally located on the first panel 50 and opens toward the bottom wall structure.

(27) With reference to FIG. 13, the bottom encapsulating panel extends from a bottom edge of one of the bottom wall structure flaps (such as the back flap). The bottom encapsulating is configured to be substantially parallel to the front panel 50 of the spout retaining member. The bottom encapsulating panel is positionable so as to be in an abutting relationship with the front panel. A spout locking slot 63 which substantially matches the spout receiving slot 60 is presented so that together they can engage and lock the spout in a generally fixed position. In certain embodiments, such a bottom encapsulating panel may be omitted (i.e., the embodiment of FIGS. 4-8).

(28) Generally, and with reference to FIGS. 14 and 15, the inner bag 16 that is associated with such a bag in box package comprises a pillow type container having a front panel 90, a back panel 92, seals 94 that couple the front panel to the back panel to define a generally rectangular or square cavity. A spout 96 is generally coupled to an opening in the front panel 90 so as to provide ingress into the cavity. The spout includes a base flange with an upstand portion extending therefrom. The base flange is typically coupled to the bag so as to provide communication with the cavity through the upstand portion. The outer surface of the upstand portion typically includes a plurality of flanges that are spaced apart from each other. These flanges are typically parallel to each other and generally parallel to the base flange. The flanges are configured to facilitate grasping by filling equipment, and are configured to receive portions of the outer carton for releasable attachment. Typically, the front and back panels may comprise a single or multi-layer laminate or co-extrusion, and may comprise a single or multi-ply configuration. In other embodiments, a gusseted bag, or other form fitting bag can be utilized in the place of a pillow type bag. The seals may be formed in any number of different manners. Additionally, the materials selected for each of the panels and the spout can be varied depending on the particular application.

(29) The tap 18 is shown in FIG. 16 as comprising a spout interface 100, flange 102, actuator 104 and dispensing opening 106. Any number of different configurations are contemplated for the tap, and the disclosure is not limited to any particular tap configuration, or any particular tap. For example, one such tap comprises the tap shown in any one of the following patents, namely, U.S. Pat. Nos. 4,619,377 and 6,978,981 both of which are issued to Roos as well as U.S. Pat. Nos. 6,045,119; 6,296,157 and 6,360,925 issued to Erb, as well as, the tap shown in U.S. Pat. No. 8,336,743 issued to Bellmore. Of course, other taps are likewise contemplated. The foregoing patents are incorporated by reference herein in their entirety. These taps are shown only for purposes of illustration, and are not deemed to be limiting or to in any manner limit the disclosure to the foregoing taps.

(30) To assemble the container of the bag in box package of the present disclosure, the user is first provided with a blank or a partially folded box, such as the blank shown in FIG. 13 (which does not show an embodiment with a frangible portion that would be in place of the triangular portions described above). Once articulated, the front wall, back wall, and first and second sidewalls are fully formed. The top wall structure and the bottom wall structure remain open. The inner spout retaining member is in position and coupled to the first sidewall and the front wall. The first panel is then oblique to each of the first sidewall and the front wall, and essentially facing the edge joining the two. In the configuration shown, the outer carton is formed from a single blank of material.

(31) The top wall structure is then assembled so as to form a three sided container with an open bottom wall structure. Generally the flaps of the bottom wall structure are folded and glued so as to be secured to each other.

(32) Next, the bag is positioned into the cavity that is bound by the two sidewalls, the back wall, the front wall and the inner spout retaining member. As the bag is further directed inward the spout and/or the tap is directed into contact with the spout receiving slot 60 of the inner spout retaining member 19. Further direction captures the spout (generally between flanges thereof), or the tap/spout (again between flanges or a combination of the two) within the spout receiving slot 60. The bag insertion continues until the entirety of the bag is within the cavity of the box. It will be understood that this can be accomplished after the bag has been filled with a predetermined amount of flowable material.

(33) Once fully inserted into the box, the bottom encapsulating panel 56 can be rotated so that it is directed toward the spout receiving slot and toward the spout positioned therein. Eventually, the spout locking slot 63 of the bottom encapsulating panel engages the spout and locks the spout into place. At such time, the tap generally faces directly at the edge between the first sidewall and the front wall.

(34) Once the bottom encapsulating panel is positioned in the desired orientation, the bottom wall structure is assembled so as to seal the bag within the box. The different flaps are folded about their respective edges until they have sealed the bottom of the box.

(35) To use the bag in box assembly, of, for example, FIGS. 1-8, the user is provided with the package. As will be understood, due to the frangible portion of the outer carton, the spout and tap remain removed from view and access. As such, the user grasps the frangible portion 40 and disconnects the same from the remainder of the outer carton. It will be understood that a number of different configurations are contemplated for the frangible portion 40 of the outer container. In certain embodiments, an angled corner cutout is contemplated, wherein the frangible portion 40 extends over the first sidewall, the front wall, and the bottom wall so as to expose the inner spout retaining member and the tap.

(36) In another embodiment, as is shown in FIG. 13, the frangible portion may be omitted. In such an embodiment, a triangular cutout and a triangle fold are provided. The portion around the tap has been removed through a triangular cut of portions of each one of the first sidewall and the front wall. Additionally, a pair of folded triangular panel sections immediately above the triangular cutout portion are provided. When articulated inwardly, these triangular portions are configured to precisely fit the portion that is between the first panel of the inner spout retaining member and the first sidewall and the front wall. Thus, access is provided to the spout while precluding access to the front panel above the spout, and into the container. Another such folded triangular portion can be provided on the corner opposite of the corner proximate the spout and tap so as to provide a handle. In addition, openings can be provided on the outer carton immediately above the tap so as to enable grasping and holding. It will be understood that the cavity that is exposed through the openings is the open cavity that is defined by the sidewall, the front wall and the first panel of the inner spout retaining member.

(37) The foregoing description merely explains and illustrates the invention and the invention is not limited thereto 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 without departing from the scope of the invention.
