## Background
BACKGROUND
1. Technical Field
This document discloses a rigid outer container for releasably accommodating a stand-up pouch that accommodates a product that can be dispensed through a corner spout of the stand-up pouch. The rigid outer container includes a slanted corner panel that releasably and frictionally receives the corner spout of the stand-up pouch.
2. Description of the Related Art
Many dry goods, like cereal, are sold in bags enclosed within a box. The bags are typically heat sealed at the top and the bottom of the bag and a “fin seal” extends along one side of the bags. These bags may be difficult to open, particularly if they are fabricated from a sturdy plastic material. Further, these types of bags typically do not have a built-in closure function. Thus, once the box and the bag are opened, the product is exposed to the atmosphere unless the consumer resorts to rolling the bag and/or using some sort of extraneous clamp or dip to help preserve the freshness of the product and to keep the product from spilling out of the bag.
On the other hand, stand-up pouches are a type of food package where the product is provided in a bag or pouch, which may have a gusseted bottom, so the pouch will stand upright on a shelf without a box. A top corner of the pouch may be removed to leave a hole that receives a threaded corner fitment, which serves as a spout through which the product is poured. A threaded cap is typically provided to close the spout. Stand-up pouches, or “SUPs,” provide an excellent airtight and re-sealable package for many food products and SUPs are easy for consumers to open and use.
However, SUPs are easy to knock over when placed on a shelf, particularly if the shelf is ventilated. In a retail setting, some SUPs are displayed in a cardboard tray that keeps the SUPs upright and aligned in a single row to present a neat and orderly appearance for customers. In contrast, other SUN hang from a metal rod and are not placed a horizontal surface at all in the retail setting. After purchase, without the support of a tray or a rod, SUPs are easily knocked over when placed on a horizontal surface, thereby making the consumer's pantry or cabinet look disorganized and untidy.
While SUPs are popular and provide a convenient and air tight package for food, there is a need for a way to stabilize SUPs on a shelf or other horizontal surface so they don't tip over as easily and so multiple SUPs can be stored together in a neat and orderly fashion.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS
FIG. 1 illustrates a stand-up pouch 20 that includes a gusseted bottom 21 that enables the stand-up pouch 20 to stand upright on a horizontal surface 22. The stand-up pouch 20 also includes a front panel 23 that is disposed between a pair of side panels, only one of which is shown at 24 in FIG. 1. The stand-up pouch 20 also includes a rear panel (not shown). The front panel 23 may include indicia 25, such as a trademark, product description, ingredients, etc. The stand-up pouch 20 further includes a top edge 26 and a slanted corner 27. The slanted corner 27 is coupled to a spout 28, the details of which will be further explained below in connection with FIGS. 5-9.
FIG. 2 illustrates a rigid outer container 30. The outer container 30 is hollow and includes an open bottom 37 for receiving the stand-up pouch 20. The outer container 30 may also include a front panel 31 that may include a window 32 so that the consumer may view the indicia 25 disposed on the front panel 23 of the stand-up pouch 20, as shown in FIG. 3. The outer container 30 includes a pair of side panels, only one of which is shown at 33 in FIG. 2, as well as a top panel 34 and a slanted corner panel 35. A slanted corner panel 35 includes an opening 36 for accommodating the spout 28 of the stand-up pouch 20. Specifically, as shown in FIG. 3, the stand-up pouch 20 may be inserted through the open bottom 37 until part of the spout 28 extends through the opening 36 in the corner panel 35. The user then grasps the spout 28 and pulls it through the opening 36, which frictionally engages the spout 28 to secure the stand-up pouch 20 within the outer container 30.
FIG. 4 is a left side view of the outer container 30, particularly illustrating a side panel 33a that features a vertical window 37a that may be used by the consumer to determine how much product 38 is disposed within the stand-up pouch 20. The side panel 33a may also include indicia 39 that indicates when the product 38 is running low inside the stand-up pouch 20 and to further provide a reminder to the consumer to purchase another stand-up pouch 20 or more product 38.
FIG. 5 illustrates a spout 26 that has been inserted through an opening 36 in a corner panel 35. To secure the spout 28 in the opening 36 and therefore the stand-up pouch 20 in place within the outer container 30, the spout 28 may include a flare 41. The flare 41 and the opening 36 are sized so that the flare 41 may be forced through the opening 36 until the lower edge 42 of the flare 41 rests on the outer surface 43 of the corner panel 35. In some embodiments, the inner surface 44 of the corner panel 35 may engage the slanted corner 27 of the stand-up pouch 20. Further, the flare 41 may be compressible to facilitate the insertion of the spout 28 through the opening 36 or removal of the spout 28 from the opening.
FIG. 6 illustrates another spout 28a that also includes a flare 41 as well as a flange 45 disposed opposite the corner panel 35 from the flare 41. The flange 45 enhances the locking relationship between the corner panel 35 and the spout 28a The flange 45 should have a diameter sufficiently large so as to prevent the flange 45 from being pulled through the opening 36 in the corner panel 35 as the spout 28a is inserted through the opening 36. Further, the flange 45 should be spaced apart from the lower edge 42 of the flare 41 to accommodate the corner panel 35 bets Teen the flare 41 and flange 45 as shown in FIG. 6.
FIG. 7 illustrates another spout 28b that is equipped with a flare 41b that may be more compressible than the flare 41 shown in FIGS. 5-6. The flares 41, 41b should be somewhat compressible to facilitate the insertion of the spouts 28, 28a, 28b through the opening 36 and removal of the spouts 28, 28a, 28b from the opening 36. The more compressible nature of the flare 41b may be appreciated by older consumers whose hands may not be strong enough to compress a more robust flare, such as the one shown at 41 in FIGS. 5-6.
FIG. 8, on the other hand, illustrates use of the flare 28 first shown in FIG. 5 with an alternative corner panel 35c that has a slanted opening 36c. Specifically, the opening 36c has a diameter at the inner surface 44c that is smaller than a diameter of the opening 36c at the outer surface 43c of the corner panel 35c. In this way, the opening 36c angles radially outwardly as it extends from the inner surface 44c to the outer surface 43c. As a result, to remove the spout 28 from its installed position shown in FIG. 8, the spout 28 is pulled downwards in the orientation of FIG. 8 and the larger diameter of the opening 36c at the outer surface 43c facilitates the passage of the flare 41 through the opening 36c. Accordingly, those with poor hand strength can still pull the spout 28 and its flare 41 through the opening 36c due to the slanted side wall of the opening 36c. Similarly, FIG. 9 illustrates an alternative spout 28d that includes a flare 41d equipped with a rounded corner 46d that is disposed between the slanted wall 47d and the bottom edge 42d of the flare 41d. The rounded corner 46d facilitates the pulling of the spout 28d downward through the opening 36 in the corner panel 35 so that the stand-up pouch 20 may be more easily removed and replaced with a new stand-up pouch 20.
As shown in FIGS. 5-9 each spout 28, 28a, 28b and 28d may include threads 47 disposed below its distal opening 47. The threads 48 receive a threaded cap 50 as shown in FIGS. 10-12. Because the cap 50 can be removed and replaced, a tamper evident feature ma be advisable or required by regulation. FIG. 10 illustrates a tamper evident mechanism in form of at least one tab 51 that couples the cap 50 to the flare 41. When the cap 50 is unscrewed from the spout 28, the tab 51 breaks, thereby warning the consumer that the cap 50 has been roved from the spout 28. In FIG. 10, the at least one tab 51 either extends around the cap 50 or a plurality of tabs 51 are disposed about the cap 50 and the spout 28 in a spaced-apart fashion. Alternatively, FIG. 11 illustrates a cap 50 with at least one tab 51a that includes a line of perforations or a score 52 that extends through the tab 51a to facilitate the breaking of the tab 51a when the cap 50 is unscrewed from the spout 28. Finally, FIG. 12 illustrates yet another alternative tab 51b with a notch 53 that facilitates breakage of the tab 51b when the cap 50 is unscrewed from the spout 28.
