DETAILED DESCRIPTION

[0035] FIG. 4 illustrates a front view of an unfilled, flexible bag or pouch 100 for use in bag-in-box packaging systems. The bag 100 may be made of, for example, plastic, and, more specifically, for example, polyethylene. Other materials may be used, and the choice of material type depends on the properties required for the bag. The bag 100 includes a front panel 26 and a rear panel 30 (FIG. 5) that are sealed together generally along their perimeters with an outer boundary seal that defines an interior region 46. By way of example, the bag 100 is quadrilateral (such as rectangular or square) in shape and the front and rear panels 26 and 30 are sealed together with top, bottom, and side seals 54, 34, 38, 42, which are connected to form the outer boundary seal. The outer boundary seal may extend along the edges of the panels 26 and 30 or may be located a short distance inward from the edges of the panels 26 and 30. The bag 100 may, of course, have other shapes. In addition or alternatively, the bag 100 may include gussets at the sides thereof that are sealed between the inner sides of the front and rear panels 26 and 30.

[0036] The bag 100 is sized to hold a gallon of fluid, but could be sized to hold different amounts of fluid. The bag 100 also includes a partial middle seal 104 extending upward from the bottom seal 34 to about halfway up the front and rear panels 26 and 30. The middle seal 104 thus divides a portion of the interior region 46 of the bag 100 into two separate compartments 108 and 112 that are in fluid communication with an open portion 114 of the interior region 46. The two separate compartments 108 and 122 thus can be in fluid communication via the open portion 114. By way of example, the seals 34, 38, 42, 54, and 104 may be made by heat sealing and create fluid-tight seals.

[0037] When the bag 100 is filled with fluid, the middle seal 104 and two compartments 108 and 112in comparison to the bag 22 of FIGS. 1-3help reduce the amount of fluid that settles into the bottom half of the interior region 46 of the bag 100 and cause more fluid to distribute upwardly within the bag 100. The bag 100 has a smaller footprint 72 than the bag 22 of FIG. 3 and is not as wide near the bottom. The bag 100 also may not be as teardrop shaped as the bag 22. For example, the bag 22 may have an approximately four inch wide footprint, and the bag 100 may have an approximately 3.25 inch wide footprint. Due to this smaller footprint and thinner and more streamlined shape, the bag 100 is less likely to get caught in the chute 60 when it is fed through the chute 60 into a box 10. In addition, the middle seal 104 reduces the volume of the bag 22 by only a very small amount, so the bag 100 still meets the volume requirements of, for example, a one gallon bag-in-box system.

[0038] FIGS. 6 and 8 show additional bags 200 and 300 that include more than one partial middle seal 104. The bag 200 of FIG. 6 includes two partial middle seals 104 and three separate compartments 108, 112, and 116 along the bottom portion of the bag 200. Accordingly, and with respect to FIGS. 5 and 7, when the bag 200 is filled with fluid, it has an even smaller footprint 72 than the bag 100.

[0039] Similarly, the bag 300 of FIG. 8 includes five partial middle seals 104 and six separate compartments 108, 112, 116, 120, 124, and 128 along the bottom portion of the bag 300. Accordingly, and with respect to FIGS. 7 and 9, when the bag 300 is filled with fluid, it has an even smaller footprint 72 than the bag 200. Thus, by increasing the number of partial seals and compartments of the bag 100, the footprint of the filled bag 100 can be decreased. This may be desirable for feeding a bag through a thinner chute and/or into thinner boxes than the ones discussed with respect to FIG. 3, such as the boxes 10 shown in FIGS. 7 and 9. It will be understood that the present technology can include bags having different numbers of partial seals and compartments than the bags shown in FIGS. 4-9.

[0040] FIG. 10 shows bags 22 and 100 each filled with about a gallon of fluid. FIG. 10 includes a mark 200 that indicates the height of the fluid level in each bag. The mark 200 for bag 22 shows that the fluid reaches, for example, about 9 and 9/16 inches above the bottom seal 34 of the bag 22. The mark 200 for the bag 100 shows that the fluid reaches, for example, about 10 and 2/16 inches above the bottom seal 34 of the bag 100. Thus, the partial seal 104 serves to push the fluid in a gallon bag upward by about 9/16 of an inch. This displacement of water reduces the size of the footprint of the bag 100.

[0041] The use of partial seals in plastic packaging has other applications besides bag-in-box packaging. For example, partial seals can be used with plastic packaging to create protective and/or insulating packaging. With respect to FIG. 11, cylindrical plastic packaging can be made by placing partial seals 104 along a plastic pouch 400 in order to define individual cylindrical compartments 404. Once the pouch 400 is filled with fluid (e.g., air or other gas, liquid, fluid insulation, etc.), the pouch 400 can then be wrapped around a cylindrical good 408 as a protective wrap. The good 408 and pouch 400 can then be positioned in a box for shipment.

[0042] With respect to FIGS. 12 and 13, packaging 500 is made up of a number of interconnected wall portions 504 that include partial seals 104 that define compartments 508. The wall portions 504 are part of a web and are connected by flexible joints or folds 510 that allow a user to fold the wall portions 504 like a box to make a protective container 512 when the packaging 500 has been filled with fluid (e.g., air or other gas, liquid, fluid insulation, etc.). The joints or folds 510 can also be perforations that allow contiguous portions 504 in the web to be separated from each other. For example, portions 504c-f can be from one web of material and be kept connected to each other and folded along lines 510 to form four walls of a housing and then portions 504a and 504b can be detached from a separate web and can be connected to the connected portions 504c-f as a top and bottom to form a housing 512 like the one shown in FIG. 13. The portions 504 can be configured to be connected to each other by fasteners such as snaps, hooks, adhesive, Velcro or any number of other suitable fasteners. The portions 504 also include fitments 534 that allow for the portion to be filled with fluid. Alternatively, several contiguous portions 504 may include only a single fitment 534 that can be used to fill all the portions 504. In such a situation, fluid is able to pass through the joints 512 and between the contiguous portions 504. In operation, the assembled container 512 of FIG. 13 can be folded and formed about a good that needs protection and/or insulation during shipment, and then the container 512 and good can be placed in a box for shipment.

[0043] With reference to FIG. 14, each wall portion 504 of packaging 500 can be defined by edge seals 520, 524, 528, and 532 such that it is its own sealed component and such that fluid does not pass between adjacent wall portions 504. In such a case, each portion 504 is filled with fluid through its own valve or fitment 534.

[0044] FIG. 15 shows another embodiment, a module component portion 600 that includes partials seals 104 that define compartments 604 within the portion. The portion 600 includes its own valve or fitment 608 that allows for the portion 600 to be filled with fluid. The portion 600 also includes connectors, fasteners, or adaptors 612 that allow for the portion 600 to be connected to other portions 600. In this way, a number of individual portions 600 can be used to create a tailor-made package protector, encasement, or even a housing.

[0045] In that regard, FIGS. 16 and 17 illustrate a plastic housing 700 that includes a series of partial seals 104 that are radially aligned with a center point and define radial compartments 710. The housing 700 includes a valve 708 that allows for filling and emptying the housing 700. When the housing 700 is filled with a fluid (e.g., air or other gas, liquid, fluid insulation, etc.), the housing 700 can be folded or formed into a dome or igloo shape. The housing 700 can then be used in many ways such as, for example, as a habitat, a flotation device, or a kind of protective cover or encasement.

[0046] FIG. 18 illustrates a variation of the cylindrical plastic packaging of FIG. 11 before it is filled with fluid. The packaging 800 is generally rectangular in shape (but can of course be other shapes) and includes a variety of parallel partial seals 104. The packaging 800 also includes sections 804 that are sealed off so that they cannot be filled with fluid or inflated. These non-inflatable sections 804 are rectangular but can have different shapes or orientations than those shown in FIG. 18. The sections 804 allow the inflated or filled packaging 800 to be folded more easily at the sections 804 to better fit around the item that is to be protected or housed in the packaging 800. The packaging 800 also includes a fitment 808 that can be used to fill the packaging with fluid. The fluid fills and inflates the packaging 800 except where the seals 104 and sections 804 are located. The side edges 812 and 814 of the packaging 800 can include fasteners that allow the edges 812 and 814 to connected to each other so that the packaging 800 and be secured around the item that is to be housed in the packaging 800. By way of example only, the edges 812 and 814 can be connected by snapable fasteners, hooks, Velcro, adhesive or any other kind of suitable fastener.
