Title: Disposable Flexible Container

Description:
FIELD 
     The present disclosure relates in general to containers, and more particularly, to containers that are flexible and disposable. 
     BACKGROUND 
     Fluent products include liquid products and/or pourable solid products. In various embodiments, a container can be used to receive, contain, and dispense one or more fluent products. And, in various embodiments, a container can be used to receive, contain, and/or dispense individual articles or separately packaged portions of a product. A container can include one or more product volumes. A product volume can be configured to be filled with one or more fluent products. A container receives a fluent product when its product volume is filled. Once filled to a desired volume, a container can be configured to contain the fluent product in its product volume, until the fluent product is dispensed. A container contains a fluent product by providing a barrier around the fluent product. The barrier prevents the fluent product from escaping the product volume. The barrier can also protect the fluent product from the environment outside of the container. A filled product volume is typically closed off by a cap or a seal. A container can be configured to dispense one or more fluent products contained in its product volume(s). Once dispensed, an end user can consume, apply, or otherwise use the fluent product(s), as appropriate. In various embodiments, a container may be configured to be refilled and reused or a container may be configured to be disposed of after a single fill or even after a single use. A container should be configured with sufficient structural integrity, such that it can receive, contain, and dispense its fluent product(s), as intended, without failure. 
     A container for fluent product(s) can be handled, displayed for sale, and put into use. A container can be handled in many different ways as it is made, filled, decorated, packaged, shipped, and unpacked. A container can experience a wide range of external forces and environmental conditions as it is handled by machines and people, moved by equipment and vehicles, and contacted by other containers and various packaging materials. A container for fluent product(s) should be configured with sufficient structural integrity, such that it can be handled in any of these ways, or in any other way known in the art, as intended, without failure. 
     A container can also be displayed for sale in many different ways as it is offered for purchase. A container can be offered for sale as an individual article of commerce or packaged with one or more other containers or products, which together form an article of commerce. A container can be offered for sale as a primary package with or without a secondary package. A container can be decorated to display characters, graphics, branding, and/or other visual elements when the container is displayed for sale. A container can be configured to be displayed for sale while laying down or standing up on a store shelf, while presented in a merchandising display, while hanging on a display hanger, or while loaded into a display rack or a vending machine. A container for fluent product(s) should be configured with a structure that allows it to be displayed in any of these ways, or in any other way known in the art, as intended, without failure. 
     A container can also be put into use in many different ways, by its end user. A container can be configured to be held and/or gripped by an end user, so a container should be appropriately sized and shaped for human hands; and for this purpose, a container can include useful structural features such as a handle and/or a gripping surface. A container can be stored while laying down or standing up on a support surface, while hanging on or from a projection such as a hook or a clip, or while supported by a product holder, or (for refillable or rechargeable containers) positioned in a refilling or recharging station. A container can be configured to dispense fluent product(s) while in any of these storage positions or while being held by the user. A container can be configured to dispense fluent product(s) through the use of gravity, and/or pressure, and/or a dispensing mechanism, such as a pump, or a straw, or through the use of other kinds of dispensers known in the art. Some containers can be configured to be filled and/or refilled by a seller (e.g. a merchant or retailer) or by an end user. A container for fluent product(s) should be configured with a structure that allows it to be put to use in any of these ways, or in any other way known in the art, as intended, without failure. A container can also be configured to be disposed of by the end user, as waste and/or recyclable material, in various ways. 
     One conventional type of container for fluent products is a rigid container made from solid material(s). Examples of conventional rigid containers include molded plastic bottles, glass jars, metal cans, cardboard boxes, etc. These conventional rigid containers are well-known and generally useful; however their designs do present several notable difficulties. 
     First, some conventional rigid containers for fluent products can be expensive to make. Some rigid containers are made by a process shaping one or more solid materials. Other rigid containers are made with a phase change process, where container materials are heated (to soften/melt), then shaped, then cooled (to harden/solidify). Both kinds of making are energy intensive processes, which can require complex equipment. 
     Second, some conventional rigid containers for fluent products can require significant amounts of material. Rigid containers that are designed to stand up on a support surface require solid walls that are thick enough to support the containers when they are filled. This can require significant amounts of material, which adds to the cost of the containers and can contribute to difficulties with their disposal. 
     Third, some conventional rigid containers for fluent products can be difficult to decorate. The sizes, shapes, (e.g. curved surfaces) and/or materials of some rigid containers, make it difficult to print directly on their outside surfaces. Labeling requires additional materials and processing, and limits the size and shape of the decoration. Overwrapping provides larger decoration areas, but also requires additional materials and processing, often at significant expense. 
     Fourth, some conventional rigid containers for fluent products can be prone to certain kinds of damage. If a rigid container is pushed against a rough surface, then the container can become scuffed, which may obscure printing on the container. If a rigid container is pressed against a hard object, then the container can become dented, which may look unsightly. And if a rigid container is dropped, then the container can rupture, which may cause its fluent product to be lost. 
     Fifth, some fluent products in conventional rigid containers can be difficult to dispense. When an end user squeezes a rigid container to dispense its fluent product, the end user must overcome the resistance of the rigid sides, to deform the container. Some users may lack the hand strength to easily overcome that resistance; these users may dispense less than their desired amount of fluent product. Other users may need to apply so much of their hand strength, that they cannot easily control how much they deform the container; these users may dispense more than their desired amount of fluent product. 
     SUMMARY 
     The present disclosure describes various embodiments of containers made from flexible material. Because these containers are made from flexible material, these containers can be less expensive to make, can use less material, and can be easier to decorate, when compared with conventional rigid containers. First, these containers can be less expensive to make, because the conversion of flexible materials (from sheet form to finished goods) generally requires less energy and complexity, than formation of rigid materials (from bulk form to finished goods). Second, these containers can use less material, because they are configured with novel support structures that do not require the use of the thick solid walls used in conventional rigid containers. Third, these flexible containers can be easier to print and/or decorate, because they are made from flexible materials, and flexible materials can be printed and/or decorated as conformable webs, before they are formed into containers. Fourth, these flexible containers can be less prone to scuffing, denting, and rupture, because flexible materials allow their outer surfaces to deform when contacting surfaces and objects, and then to bounce back. Fifth, fluent products in these flexible containers can be more readily and carefully dispensed, because the sides of flexible containers can be more easily and controllably squeezed by human hands. Even though the containers of the present disclosure are made from flexible material, they can be configured with sufficient structural integrity, such that they can receive, contain, and dispense fluent product(s), as intended, without failure. Also, these containers can be configured with sufficient structural integrity, such that they can withstand external forces and environmental conditions from handling, without failure. Further, these containers can be configured with structures that allow them to be displayed and put into use, as intended, without failure. 
     In an exemplary embodiment, a disposable flexible container for a fluent product in accordance with the disclosure comprises a product volume at least partially defined by a nonstructural panel and a structural support volume arranged to generate and maintain tension in the nonstructural panel when the structural support volume is expanded. The disposable flexible container also includes a dispenser for dispensing the fluent product from the product volume. Preferably, the nonstructural panel which at least partially defines the product volume has at least one pair of opposed sides and the disposable flexible container has a structural support volume associated with, or in proximity to, each of the opposed sides of the nonstructural panel in spaced apart relation at a distance from one another. 
     In one embodiment, the nonstructural panel includes a perimeter and one or more structural support volumes surround at least 50% of the nonstructural panel in association with, or in proximity to, the perimeter of the nonstructural panel. 
     In another embodiment, the nonstructural panel has first and second pairs of opposed sides and one or more structural support volumes surround the nonstructural panel in association with, or in proximity to, the first pair of opposed sides and at least one of the second pair of opposed sides. 
     In still another embodiment, one or more structural support volumes substantially surround the nonstructural panel in association with, or in proximity to, the first and second pairs of opposed sides to impart tension to the nonstructural panel at least between one of the first and second pairs of opposed sides. In this embodiment, the structural support volumes may comprise a first pair of opposed structural support volumes in association with, or in proximity to, the first pair of opposed sides of the nonstructural panel to impart tension to the nonstructural panel and a second pair of opposed structural support volumes in association with, or in proximity to the second pair of opposed sides to maintain the first pair of structural support volumes in spaced relation a distance apart from one another. In yet another embodiment, the structural support volume may comprise a single continuous structural support volume substantially surrounding the nonstructural panel in proximity to the first and second pairs of opposed sides to impart tension through both of the first and second pairs of opposed sides of the nonstructural panel. 
     In a further respect, the disposable flexible container in accordance with the disclosure includes at least two flexible panels wherein at least one of the flexible panels is a nonstructural panel, wherein the nonstructural panel has opposed sides, and including a structural support volume associated with one or both of the opposed sides of the nonstructural panel. 
     In all of the embodiments, the nonstructural panel may comprise a flexible squeeze panel for dispensing the fluent product from the product volume through the dispenser and, for this purpose, the flexible squeeze panel may have a dimensionless tensile stress at least at least at some point or for some portion of the non-structural panel in the range of about 1E-6 to about 20, preferably, a dimensionless tensile stress in the range of about 4E-5 to about 10 and, more preferably, a dimensionless tensile stress in the range of about 2E-3 to about 0.9.

     DETAILED DESCRIPTION 
     The present disclosure describes various embodiments of containers made from flexible material. Because these containers are made from flexible material, these containers can be less expensive to make, can use less material, and can be easier to decorate, when compared with conventional rigid containers. First, these containers can be less expensive to make, because the conversion of flexible materials (from sheet form to finished goods) generally requires less energy and complexity, than formation of rigid materials (from bulk form to finished goods). Second, these containers can use less material, because they are configured with novel support structures that do not require the use of the thick solid walls used in conventional rigid containers. Third, these flexible containers can be easier to decorate, because their flexible materials can be easily printed before they are formed into containers. Fourth, these flexible containers can be less prone to scuffing, denting, and rupture, because flexible materials allow their outer surfaces to deform when contacting surfaces and objects, and then to bounce back. Fifth, fluent products in these flexible containers can be more readily and carefully dispensed, because the sides of flexible containers can be more easily and controllably squeezed by human hands. 
     Even though the containers of the present disclosure are made from flexible material, they can be configured with sufficient structural integrity, such that they can receive, contain, and dispense fluent product(s), as intended, without failure. Also, these containers can be configured with sufficient structural integrity, such that they can withstand external forces and environmental conditions from handling, without failure. Further, these containers can be configured with structures that allow them to be displayed for sale and put into use, as intended, without failure. 
     As used herein, the term “about” modifies a particular value, by referring to a range equal to the particular value, plus or minus twenty percent (+/−20%). For any of the embodiments of flexible containers, disclosed herein, any disclosure of a particular value, can, in various alternate embodiments, also be understood as a disclosure of a range equal to about that particular value (i.e. +/−20%). 
     As used herein, the term “ambient conditions” refers to a temperature within the range of 15-35 degrees Celsius and a relative humidity within the range of 35-75%. 
     As used herein, the term “approximately” modifies a particular value, by referring to a range equal to the particular value, plus or minus fifteen percent (+/−15%). For any of the embodiments of flexible containers, disclosed herein, any disclosure of a particular value, can, in various alternate embodiments, also be understood as a disclosure of a range equal to approximately that particular value (i.e. +/−15%). 
     As used herein, when referring to a sheet of material, the term “basis weight” refers to a measure of mass per area, in units of grams per square meter (gsm). For any of the embodiments of flexible containers, disclosed herein, in various embodiments, any of the flexible materials can be configured to have a basis weight of 10-1000 gsm, or any integer value for gsm from 10-1000, or within any range formed by any of these values, such as 20-800 gsm, 30-600 gsm, 40-400 gsm, or 50-200, etc. 
     As used herein, when referring to a flexible container, the term “bottom” refers to the portion of the container that is located in the lowermost 30% of the overall height of the container, that is, from 0-30% of the overall height of the container. As used herein, the term bottom can be further limited by modifying the term bottom with a particular percentage value, which is less than 30%. For any of the embodiments of flexible containers, disclosed herein, a reference to the bottom of the container can, in various alternate embodiments, refer to the bottom 25% (i.e. from 0-25% of the overall height), the bottom 20% (i.e. from 0-20% of the overall height), the bottom 15% (i.e. from 0-15% of the overall height), the bottom 10% (i.e. from 0-10% of the overall height), or the bottom 5% (i.e. from 0-5% of the overall height), or any integer value for percentage between 0% and 30%. 
     As used herein, the term “branding” refers to a visual element intended to distinguish a product from other products. Examples of branding include one of more of any of the following: trademarks, trade dress, logos, icons, and the like. For any of the embodiments of flexible containers, disclosed herein, in various embodiments, any surface of the flexible container can include one or more brandings of any size, shape, or configuration, disclosed herein or known in the art, in any combination. 
     As used herein, the term “character” refers to a visual element intended to convey information. Examples of characters include one or more of any of the following: letters, numbers, symbols, and the like. For any of the embodiments of flexible containers, disclosed herein, in various embodiments, any surface of the flexible container can include one or more characters of any size, shape, or configuration, disclosed herein or known in the art, in any combination. 
     As used herein, the term “closed” refers to a state of a product volume, wherein fluent products within the product volume are prevented from escaping the product volume (e.g. by one or more materials that form a barrier, and by a cap), but the product volume is not necessarily hermetically sealed. For example, a closed container can include a vent, which allows a head space in the container to be in fluid communication with air in the environment outside of the container. 
     As used herein, the term “directly connected” refers to a configuration wherein elements are attached to each other without any intermediate elements therebetween, except for any means of attachment (e.g. adhesive). 
     As used herein, when referring to a flexible container, the term “dispenser” refers to a structure configured to dispense fluent product(s) from a product volume and/or from a mixing volume to the environment outside of the container. For any of the flexible containers disclosed herein, any dispenser can be configured in any way disclosed herein or known in the art, including any suitable size, shape, and flow rate. For example, a dispenser can be a push-pull type dispenser, a dispenser with a flip-top cap, a dispenser with a screw-on cap, a rotatable type dispenser, dispenser with a cap, a pump type dispenser, a pump spray type dispenser, a trigger spray type dispenser, a straw dispenser, a flip up straw dispenser, a straw dispenser with bite valve, a dosing dispenser, etc. A dispenser can be a parallel dispenser, providing multiple flow channels in fluid communication with multiple product volumes, wherein those flow channels remain separate until the point of dispensing, thus allowing fluent products from multiple product volumes to be dispensed as separate fluent products, dispensed together at the same time. A dispenser can be a mixing dispenser, providing one or more flow channels in fluid communication with multiple product volumes, with multiple flow channels combined before the point of dispensing, thus allowing fluent products from multiple product volumes to be dispensed as the fluent products mixed together. As another example, a dispenser can be formed by a frangible opening. As further examples, a dispenser can utilize one or more valves and/or dispensing mechanisms disclosed in the art, such as those disclosed in: published US patent application 2003/0096068, entitled “One-way valve for inflatable package”; U.S. Pat. No. 4,988,016 entitled “Self-sealing container”; and U.S. Pat. No. 7,207,717, entitled “Package having a fluid actuated closure”; each of which is hereby incorporated by reference. Still further, any of the dispensers disclosed herein, may be incorporated into a flexible container either directly, or in combination with one or more other materials or structures (such as a fitment), or in any way known in the art. In some alternate embodiments, dispensers disclosed herein can be configured for both dispensing and filling, to allow filling of product volume(s) through one or more dispensers. In other alternate embodiments, a product volume can include one or more filling structure(s) (e.g. for adding water to a mixing volume) in addition to or instead of one or more dispenser(s). Any location for a dispenser, disclosed herein can alternatively be used as a location for a filling structure. 
     As used herein, when referring to a flexible container, the term “disposable” refers to a container which, after dispensing a product to an end user, is not configured to be refilled with an additional amount of the product, but is configured to be disposed of (i.e. as waste, compost, and/or recyclable material). Part, parts, or all of any of the embodiments of flexible containers, disclosed herein, can be configured to be disposable. 
     As used herein, when referring to a flexible container, the term “durable” refers to a container that is reusable more than non-durable containers. 
     As used herein, when referring to a flexible container, the term “effective base contact area” refers to a particular area defined by a portion of the bottom of the container, when the container (with all of its product volume(s) filled 100% with water) is standing upright and its bottom is resting on a horizontal support surface. The effective base contact area lies in a plane defined by the horizontal support surface. The effective base contact area is a continuous area bounded on all sides by an outer periphery. 
     The outer periphery is formed from an actual contact area and from a series of projected areas from defined cross-sections taken at the bottom of the container. The actual contact area is the one or more portions of the bottom of the container that contact the horizontal support surface, when the effective base contact area is defined. The effective base contact area includes all of the actual contact area. However, in some embodiments, the effective base contact area may extend beyond the actual contact area. 
     The series of projected area are formed from five horizontal cross-sections, taken at the bottom of the flexible container. These cross-sections are taken at 1%, 2%, 3%, 4%, and 5% of the overall height. The outer extent of each of these cross-sections is projected vertically downward onto the horizontal support surface to form five (overlapping) projected areas, which, together with the actual contact area, form a single combined area. This is not a summing up of the values for these areas, but is the formation of a single combined area that includes all of these (projected and actual) areas, overlapping each other, wherein any overlapping portion makes only one contribution to the single combined area. 
     The outer periphery of the effective base contact area is formed as described below. In the following description, the terms convex, protruding, concave, and recessed are understood from the perspective of points outside of the combined area. The outer periphery is formed by a combination of the outer extent of the combined area and any chords, which are straight line segments constructed as described below. 
     For each continuous portion of the combined area that has an outer perimeter with a shape that is concave or recessed, a chord is constructed across that portion. This chord is the shortest straight line segment that can be drawn tangent to the combined area on both sides of the concave/recessed portion. 
     For a combined area that is discontinuous (formed by two or more separate portions), one or more chords are constructed around the outer perimeter of the combined area, across the one or more discontinuities (open spaces disposed between the portions). These chords are straight lines segments drawn tangent to the outermost separate portions of the combined area. These chords are drawn to create the largest possible effective base contact area. 
     Thus, the outer periphery is formed by a combination of the outer extent of the combined area and any chords, constructed as described above, which all together enclose the effective base area. Any chords that are bounded by the combined area and/or one or more other chords, are not part of the outer periphery and should be ignored. 
     Any of the embodiments of flexible containers, disclosed herein, can be configured to have an effective base contact area from 1 to 50,000 square centimeters (cm 2 ), or any integer value for cm 2  between 1 and 50,000 cm 2 , or within any range formed by any of the preceding values, such as: from 2 to 25,000 cm 2 , 3 to 10,000 cm 2 , 4 to 5,000 cm 2 , 5 to 2,500 cm 2 , from 10 to 1,000 cm 2 , from 20 to 500 cm 2 , from 30 to 300 cm 2 , from 40 to 200 cm 2 , or from 50 to 100 cm 2 , etc. 
     As used herein, when referring to a flexible container, the term “expanded” refers to the state of one or more flexible materials that are configured to be formed into a structural support volume, after the structural support volume is made rigid by one or more expansion materials. An expanded structural support volume has an overall width that is significantly greater than the combined thickness of its one or more flexible materials, before the structural support volume is filled with the one or more expansion materials. Examples of expansion materials include liquids (e.g. water), gases (e.g. compressed air), fluent products, foams (that can expand after being added into a structural support volume), co-reactive materials (that produce gas), or phase change materials (that can be added in solid or liquid form, but which turn into a gas; for example, liquid nitrogen or dry ice), or other suitable materials known in the art, or combinations of any of these (e.g. fluent product and liquid nitrogen).

     In additional embodiments, any stand up flexible container with a structural support frame, as disclosed herein, can be configured to have an overall shape that corresponds with any other known three-dimensional shape, including any kind of polyhedron, any kind of prismatoid, and any kind of prism (including right prisms and uniform prisms). 
       FIG. 9A  illustrates a top view of an embodiment of a self-supporting flexible container  900 , having an overall shape like a square.  FIG. 9B  illustrates an end view of the flexible container  900  of  FIG. 9A . The container  900  is resting on a horizontal support surface  901 . 
     In  FIG. 9B , a coordinate system  910 , provides lines of reference for referring to directions in the figure. The coordinate system  910  is a three-dimensional Cartesian coordinate system, with an X-axis, a Y-axis, and a Z-axis. The X-axis and the Z-axis are parallel with the horizontal support surface  901  and the Y-axis is perpendicular to the horizontal support surface  901 . 
       FIG. 9A  also includes other lines of reference, for referring to directions and locations with respect to the container  100 . A lateral centerline  911  runs parallel to the X-axis. An XY plane at the lateral centerline  911  separates the container  100  into a front half and a back half. An XZ plane at the lateral centerline  911  separates the container  100  into an upper half and a lower half. A longitudinal centerline  914  runs parallel to the Y-axis. A YZ plane at the longitudinal centerline  914  separates the container  900  into a left half and a right half. A third centerline  917  runs parallel to the Z-axis. The lateral centerline  911 , the longitudinal centerline  914 , and the third centerline  917  all intersect at a center of the container  900 . These terms for direction, orientation, measurement, and disposition, in the embodiment of  FIGS. 9A-9B  are the same as the like-numbered terms in the embodiment of  FIGS. 1A-1D . 
     The container  900  includes a top  904 , a middle  906 , and a bottom  908 , the front  902 - 1 , the back  902 - 2 , and left and right sides  909 . In the embodiment of  FIGS. 9A-9B , the upper half and the lower half of the container are joined together at a seal  929 , which extends around the outer periphery of the container  900 . The bottom of the container  900  is configured in the same way as the top of the container  900 . 
     The container  900  includes a structural support frame  940 , a product volume  950 , a dispenser  960 , a top panel  980 - t  and a bottom panel (not shown). A portion of the top panel  980 - t  is illustrated as broken away, in order to show the product volume  950 . The product volume  950  is configured to contain one or more fluent products. The dispenser  960  allows the container  900  to dispense these fluent product(s) from the product volume  950  through a flow channel  959  then through the dispenser  960 , to the environment outside of the container  900 . The structural support frame  940  supports the mass of fluent product(s) in the product volume  950 . The top panel  980 - t  and the bottom panel are relatively flat surfaces, overlaying the product volume  950 , and are suitable for displaying any kind of indicia. 
     The structural support frame  940  is formed by a plurality of structural support members. The structural support frame  940  includes front structural support members  943 - 1  and  943 - 2 , intermediate structural support members  945 - 1 ,  945 - 2 ,  945 - 3 , and  945 - 4 , as well as back structural support members  947 - 1  and  947 - 2 . Overall, each of the structural support members in the container  900  is oriented horizontally. And, each of the structural support members in the container  900  has a cross-sectional area that is substantially uniform along its length, although in various embodiments, this cross-sectional area can vary. 
     Upper structural support members  943 - 1 ,  945 - 1 ,  945 - 2 , and  947 - 1  are disposed in an upper part of the middle  906  and in the top  904 , while lower structural support members  943 - 2 ,  945 - 4 ,  945 - 3 , and  947 - 2  are disposed in a lower part of the middle  906  and in the bottom  908 . The upper structural support members  943 - 1 ,  945 - 1 ,  945 - 2 , and  947 - 1  are disposed above and adjacent to the lower structural support members  943 - 2 ,  945 - 4 ,  945 - 3 , and  947 - 2 , respectively. 
     In various embodiments, adjacent upper and lower structural support members can be in contact with each other at one or more relatively smaller locations and/or at one or more relatively larger locations, along part, or parts, or about all, or approximately all, or substantially all, or nearly all, or all of their overall lengths, so long as there is a gap in the contact for the flow channel  959 , between the structural support members  943 - 1  and  943 - 2 . In the embodiment of  FIGS. 9A-9B , the upper and lower structural support members are not directly connected to each other. However, in various alternate embodiments, adjacent upper and lower structural support members can be directly connected and/or joined together along part, or parts, or about all, or approximately all, or substantially all, or nearly all, or all of their overall lengths. 
     The ends of structural support members  943 - 1 ,  945 - 2 ,  947 - 1 , and  945 - 1  are joined together to form a top square that is outward from and surrounding the product volume  950 , and the ends of structural support members  943 - 2 ,  945 - 3 ,  947 - 2 , and  945 - 4  are also joined together to form a bottom square that is outward from and surrounding the product volume  950 . In the structural support frame  940 , the ends of the structural support members, which are joined together, are directly connected, all around the periphery of their walls. However, in various alternative embodiments, any of the structural support members of the embodiment of  FIGS. 9A-9B  can be joined together in any way described herein or known in the art. 
     In alternative embodiments of the structural support frame  940 , adjacent structural support members can be combined into a single structural support member, wherein the combined structural support member can effectively substitute for the adjacent structural support members, as their functions and connections are described herein. In other alternative embodiments of the structural support frame  940 , one or more additional structural support members can be added to the structural support members in the structural support frame  940 , wherein the expanded structural support frame can effectively substitute for the structural support frame  940 , as its functions and connections are described herein.

FIG. 10B  illustrates an end view of the flexible container  1000  of  FIG. 10B , resting on a horizontal support surface  1001 . 
       FIG. 11A  illustrates a top view of an embodiment of a self-supporting flexible container  1100  (that is not a stand up flexible container) having a product volume  1150  and an overall shape like a circle. The support frame  1140  is formed by structural support members disposed around the circumference of the circular shape and joined together at their ends. The structural support members define a circular shaped top panel  1180 - t , and a circular shaped bottom panel (not shown). The top panel  1180 - t  and the bottom panel are about flat, however in various embodiments, part, parts, or about all, or approximately all, or substantially all, or nearly all, or all of any of the side panels can be approximately flat, substantially flat, nearly flat, or completely flat. The container  1100  includes a dispenser  1160 , which is configured to dispense one or more fluent products from one or more product volumes disposed within the container  1100 . In the embodiment of  FIG. 11A , the dispenser  1160  is disposed in the center of the front, however, in various alternate embodiments, the dispenser  1160  can be disposed anywhere else on the top, sides, or bottom, of the container  1100 .

     In all of the foregoing embodiments, and any other embodiments constructed in accordance with the disclosure, it will be appreciated that the panels, e.g.,  180 - 1 ,  180 - 2  of  FIGS. 1A-1D, 280-1-280-4  of  FIGS. 2A-2D, 380-1-380-4  of  FIGS. 3A-3D, 480-1, 480-3  of  FIGS. 4A-4D, 580-1, 580-4  of  FIGS. 5A-5D, 680-1, 680-5  of  FIGS. 6A-6D, 780-1, 780-3  of  FIGS. 7A-7D, 880-1, 880-4  of  FIGS. 8A-8D, 980 - t  and a bottom panel (not shown) of  FIGS. 9A-9B, 1080 - t  and a bottom panel (not shown) of  FIGS. 10A-10B, and 1180 - t , and a bottom panel (not shown) of  FIGS. 11A-11B , can comprise nonstructural (or flexible squeeze) panels that are opposed to one another in the sense that there is at least some fluent product between any two of the panels in each embodiment so that fluent product can be dispensed when any two or more of the panels are squeezed toward one another. In any embodiment, squeeze panels may be arranged to be squeezed toward each other to dispense a fluent product from the container. The squeeze panels may be co-facially arranged, or arranged at any other orientation. The squeeze panels may be arranged such that they are squeezed toward the center of the container to dispense a fluent product. 
     Also, in all of the foregoing embodiments, and any other embodiments constructed in accordance with the disclosure, it will be appreciated that the structural support frames, e.g.,  140  in  FIGS. 1A-1D, 240  of  FIGS. 2A-2D, 340  of  FIGS. 3A-3D, 440  of  FIGS. 4A-4D, 540  of  FIGS. 5A-5D, 640  of  FIGS. 6A-6D, 740  of  FIGS. 7A-7D, 840  of  FIGS. 8A-8D, 940  of  FIGS. 9A-9B, 1040  of  FIGS. 10A-10B, and 1140  of  FIGS. 11A-11B , can comprise one or more structural support members which take the form of expanded structural support volumes. 
     In all of the foregoing embodiments, and any other embodiments constructed in accordance with the disclosure, the nonstructural (or flexible) squeeze panels identified above in connection with the embodiments of  FIGS. 1A-1D, 2A-2D, 3A-3D, 4A-4D, 5A-5D, 6A-6D, 7A-7D, 8A-8D, 9A-9D, 10A-10D, and 11A - 11 D have opposed sides and an expanded structural support volume which makes up the structural support frames  140 ,  240 ,  340 ,  440 ,  540 ,  640 ,  740 ,  840 ,  940 ,  1040 , and  1140 , associated with each of the opposed sides. The structural support volume or volumes can have at least some curvature and be disposed in generally concave spaced relation to one another (e.g., see structural support volumes  146 - 1 ,  146 - 2  in  FIG. 1A ), they can be generally straight and be disposed generally at an angle to one another (e.g., see structural support volumes  246 - 1 ,  246 - 2 ,  246 - 3 ,  246 - 4  of  FIG. 2A ), or they can be generally straight and be disposed in generally parallel relation to one another (e.g., see structural support volumes  446 - 1 ,  446 - 2 ,  446 - 3  in  FIG. 4C ), or they can have various other shapes and/or relationships to one another. 
     Referring again to  FIGS. 1A-1D , a flexible container in accordance with the disclosure can be formed of various different flexible materials and/or laminates having the requisite characteristics to be capable of containing and dispensing a fluent product while being disposable after the fluent product has been fully dispensed. In a broad sense, a flexible container in accordance with the disclosure, such as the flexible container  100  in  FIGS. 1A-1D , will have a product volume, such as  150 , at least partially defined by a panel, such as  180 - 1 , which may be configured to be a nonstructural panel. To provide support for a defined shape, a flexible container in accordance with the disclosure, such as the flexible container  100  in  FIGS. 1A-1D , includes a structural support volume, such as structural support members  146 - 1 ,  146 - 2 , arranged to generate and maintain tension in the nonstructural panel, such as  180 - 1 , when the structural support volume is expanded. 
     Still referring to  FIGS. 1A-1D , the flexible container in accordance with the disclosure also includes a dispenser, such as  160 , for dispensing a fluent product from the product volume, such as  150 , through, e.g., a flow channel, such as  159 , to the environment outside the flexible container. One of the unique aspects of the disclosure is that the flexible container, such as  100  in  FIGS. 1A-1D , has a nonstructural panel, such as  180 - 1 , that is maintained under tension akin to a drum head as a result of the effect of the structural support volume, i.e., structural support members  146 - 1 ,  146 - 2 . The manner in which tension is generated and maintained by the structural support volume, i.e., structural support members  146 - 1 ,  146 - 2 , is explained below but, as a result of the tension, the nonstructural panel, such as  180 - 1 , becomes a flexible squeeze panel that resists deformation, facilitates dispensing fluent product through the dispenser  160 , and springs back after it is squeezed. 
     In order to understand this phenomenon,  FIGS. 15A-15D  illustrate a nonstructural panel  1580  disposed between structural support volumes  1546 - 1  and  1546 - 2  that are suitably maintained a relatively fixed distance apart.  FIG. 15A  illustrates the nonstructural panel  1580  before expansion of the structural support volumes  1546 - 1  and  1546 - 2 ,  FIG. 15B  illustrates the nonstructural panel  1580  after expansion of the structural support volumes  1546 - 1  and  1546 - 2 ,  FIG. 15C  illustrates the nonstructural panel  1580  after expansion of the structural support volumes  1546 - 1  and  1546 - 2  while applying a squeeze force, and  FIG. 15D  is a top plan view illustrating the nonstructural panel  1580  disposed between the structural support volumes  1546 - 1  and  1546 - 2  while applying a squeeze force, and these views illustrate various different parameters utilized in equations leading to a determination of total squeeze force. The concept of total squeeze force in connection with flexible containers incorporates three separate force components that make up the total squeeze force for an arrangement such as the one which is illustrated in  FIGS. 15A-15C . 
     The total squeeze force is nondimensionalized to be expressed as a dimensionless squeeze force as: 
     
       
      
       F*=F 
       total 
       /EWt  
      
     
     where the total squeeze force (F total ) is determined by the following equation: 
         F   total =[2· W·E·t ·sin·θ·σ*]+[ W·E·t ·tan·θ·(1−cos θ)]+[(2 E·W·t   3 ·tan θ)/( L   2 )]
 
       {Force Component 1}{Force Component 2}{Force Component 3} 
     where:
 
Force Component 1=squeeze force due to initial tension in the nonstructural panel
 
Force Component 2=squeeze force due to elongation of the nonstructural panel
 
Force Component 3=squeeze force due to pure bending of the nonstructural panel
 
and where:
 
W=width of the nonstructural panel
 
E=elastic modulus of the nonstructural panel material
 
t=thickness of the nonstructural panel material
 
θ=angle of deflection of the nonstructural panel
 
σ*=dimensionless tensile stress in the nonstructural panel (σ*=σ/E)
 
L=separation distance of the structural support volumes
 
d=the width of the structural support volume in an unexpanded state
 
α=structure index (α=d/L)
 
and where:
 
σ* is determined by the formula:
 
       σ*=2α(1−Γ) and where:
 
     Γ is a function of ψ determined by the formula: 
     
       
         
           
             Γ

For squeeze panels in some embodiments, the second and third terms of the squeeze force equation (elongation and bending, respectively) can be neglected as they are very small in comparison with the first term (initial tension component).
 
     By utilizing the foregoing equations, the nonstructural panel of the flexible container in accordance with the disclosure comprises a flexible squeeze panel having a dimensionless squeeze force F* in the range of about 5E-9 to about 30 at least at some point or for some portion of the panel. Preferably, the flexible squeeze panel has a dimensionless squeeze force F* in the range of about 2E-7 to about 3 and, more preferably, in the range of about 1E-5 to about 1 at least at some point or for some portion of the panel. 
     Based upon the foregoing equations, the flexible squeeze panel of the flexible container has a dimensionless squeeze force to mass ratio (F* l m where m=mass of the flexible squeeze panel) in the range of about 1E-10 to about 30 g −1  at least at some point or for some portion of the panel. Preferably, the flexible squeeze panel has a dimensionless squeeze force to mass ratio (F* l /m) in the range of about 1E-7 to about 1 g −1  and, more preferably, in the range of about 1E-5 to about 0.1 g −1  at least at some point or for some portion of the panel. 
     The flexible squeeze panel of the flexible container has a dimensionless squeeze force to thickness ratio (F* l t where t=thickness of the flexible squeeze panel) in the range of about 1E-11 to about 6 (μm −1 ) at least at some point or for some portion of the panel. Preferably, the flexible squeeze panel has a dimensionless squeeze force to thickness ratio (F* l t) in the range of about 2E-8 to about 0.2 (μm −1 ) and, more preferably, in the range of about 1E-6 to about 0.01 (μm −1 ) at least at some point or for some portion of the panel. 
     In accordance with the disclosure, at least the flexible squeeze panel of the flexible container has a thickness (t) in the range of about 10 to about 500 micrometers (μm) and, preferably, a thickness in the range of about 20 to about 400 micrometers (μm). Preferably, at least the flexible squeeze panel of the flexible container has a thickness (t) in the range of about 30 to about 300 micrometers (μm) and, more preferably, at least the flexible squeeze panel has a thickness in the range of about 40 to about 200 micrometers (μm). Still more preferably, and in accordance with the disclosure, at least the flexible squeeze panel of the flexible container has a thickness (t) in the range of about 50 to about 200 micrometers (μm). 
     From the equation for total squeeze force for a nonstructural panel of a flexible container and, specifically, for a flexible squeeze panel, i.e., from F total =[2·W·E·t·sin θ·σ*]+[W·E·t·tan θ·(1−cos θ)]+[2·E·W·t 3 ·tan θ/L 2 ], it is possible to understand the significantly reduced amount of material that can be used to generate the same effective structure as would be found in a rigid container. For a flexible container as disclosed herein, having a flexible squeeze panel, in some embodiments, the squeeze force from the initial tension portion of the equation can be the majority of the overall squeeze force and, in other embodiments, it can be significantly more than the majority to about all of the total squeeze force. 
     In another respect, and based upon the foregoing equations, the flexible squeeze panel has a dimensionless tension (σ*) in the range of about 1E-6 to about 20, preferably, in the range of about 4E-5 to about 10 and, more preferably, in the range of about 2E-3 to about 0.9 at least at some point or for some portion of the panel. 
     In yet another respect, and based upon the foregoing equations, the flexible squeeze panel of the flexible container has a dimensionless stiffness index (ψ) in the range of about 2E-5 to about 1.5E3, preferably, in the range of about 3E-4 to about 100 and, more preferably, in the range of about 0.01 to about 20 at least at some point or for some portion of the panel. 
     In yet another respect, the flexible squeeze panel has a dimensionless structure index (α) in the range of about 0.001 to about 20, preferably, in the range of about 0.01 to about 10 and, more preferably, in the range of about 0.04 to about 1 at least at some point or for some portion of the panel. 
     In order to further understand the principle behind the use of one or more structural support volumes to generate and maintain tension in a nonstructural panel to create a tensioned flexible squeeze panel,  FIGS. 16A-16F  illustrate various arrangements and conditions for a tensioned flexible squeeze panel  1680 - 1  having one or more structural support volumes  1646 - 1 ,  1646 - 2 ,  1646 - 3 ,  1646 - 4 . 
     Referring to  FIG. 16A , the nonstructural panel  1680 - 1  has opposed fixed sides  1682 - 1 ,  1682 - 2  and the structural support volume  1646 - 1  is disposed at a point intermediate the fixed sides  1682 - 1 ,  1682 - 2  of the nonstructural panel  1680 - 1 . When the structural support volume  1646 - 1  is expanded, e.g., by inflation, tension is generated and maintained in the nonstructural panel  1680 - 1  as represented by the arrows  1699 - 1  and  1699 - 2  on either side of the structural support volume  1646 - 1 . 
     Referring next to  FIG. 16B , the nonstructural panel  1680 - 1  has opposed fixed sides  1682 - 1 ,  1682 - 2  and the structural support volume  1646 - 1  is associated with one of the fixed sides, i.e., fixed side  1682 - 1 , of the nonstructural panel  1680 - 1 . When the structural support volume  1646 - 1  is expanded, tension is generated and maintained in the nonstructural panel  1680 - 1  as represented by the arrow  1699 - 1  on the panel side of the structural support volume  1646 - 1 . 
     Referring to  FIG. 16C , the nonstructural panel  1680 - 1  has opposed fixed sides  1682 - 1 ,  1682 - 2  and one of the structural support volumes  1646 - 1 ,  1646 - 2  is associated with each of the fixed sides  1682 - 1 ,  1682 - 1  of the nonstructural panel  1680 - 1 . When the structural support volumes  1646 - 1 ,  1646 - 2  are expanded, tension is generated and maintained in the nonstructural panel  1680 - 1  as represented by the arrow  1699 - 1  between the structural support volumes  1646 - 1 ,  1646 - 2 . The two structural support volumes are at a separation distance of L from each other as indicated. 
     Referring next to  FIG. 16D , the nonstructural panel  1680 - 1  includes a perimeter which, as illustrated, has opposed fixed sides  1682 - 1 ,  1682 - 2  and the structural support volume  1646 - 1  surrounds at least about 50% of the nonstructural panel  1680 - 1  in association with, or proximity to, the perimeter of the nonstructural panel. 
     More specifically, and still referring to  FIG. 16D , the nonstructural panel  1680 - 1  includes first and second pairs of opposed sides and, in particular, opposed fixed sides  1682 - 1 ,  1682 - 2  as well as opposed sides  1682 - 3 ,  1682 - 4  extending between opposed fixed sides  1682 - 1 ,  1682 - 2  and, in the illustrated embodiment, the structural support volume  1646 - 1  surrounds the nonstructural panel  1680 - 1  in association with, or proximity to, the first pair of opposed fixed sides  1682 - 1 ,  1682 - 2  and at least one of the second pair of opposed sides  1682 - 3 . 
     When the structural support volume  1646 - 1  is expanded, tension is generated and maintained in the nonstructural panel  1680 - 1  as represented by the arrow  1699 - 1  between the structural support volume portions  1646 - 1   a ,  1641 - 1   b.    
     Referring to  FIG. 16E , the nonstructural panel  1680 - 1  includes first and second pairs of opposed sides and, in particular, opposed sides  1682 - 1 ,  1682 - 2  as well as opposed sides  1682 - 3 ,  1682 - 4  extending between opposed sides  1682 - 1 ,  1682 - 2  and, in the illustrated embodiment, the structural support volumes  1646 - 1 ,  1646 - 2 ,  1646 - 3 ,  1646 - 4  surround the nonstructural panel  1680 - 1  in association with, or proximity to, the first and second pairs of opposed sides  1682 - 1 ,  1682 - 2 ,  1682 - 3 ,  1682 - 4 , respectively. In this embodiment, the structural support volumes  1646 - 1 ,  1646 - 2 ,  1646 - 3 ,  1646 - 4  comprise a first pair of opposed structural support volumes ( 1646 - 1 ,  1646 - 2 ) in proximity to the first pair of opposed sides  1682 - 1 ,  1682 - 2  to impart tension to the nonstructural panel  1680 - 1  and a second pair of opposed structural support volumes ( 1646 - 3 ,  1646 - 4 ) in proximity to the second pair of opposed sides  1682 - 3 ,  1682 - 4  to maintain the first pair of opposed structural support volumes ( 1646 - 1 ,  1646 - 2 ) a distance apart. When the structural support volumes  1646 - 1 ,  1646 - 2 ,  1646 - 3 ,  1646 - 4  are expanded, the structural support volumes ( 1646 - 3 ,  1646 - 4 ) maintain the opposed structural support volumes ( 1646 - 1 ,  1646 - 2 ) in spaced apart relation at a distance from one another, and the structural support volumes ( 1646 - 1 ,  1646 - 2 ) cause tension to be generated and maintained in the nonstructural panel  1680 - 1  as represented by the arrow  1699 - 1  between the structural support volumes  1646 - 1 ,  1646 - 2 . There is also a tension generated in the perpendicular direction, but because the spacing between opposed structural support volumes is greater, the tension level is less, in accordance with the equations above. 
     Referring to  FIG. 16F , the nonstructural panel  1680 - 1  includes first and second pairs of opposed sides and, in particular, opposed sides  1682 - 1 ,  1682 - 2  as well as opposed sides  1682 - 3 ,  1682 - 4  extending between opposed sides  1682 - 1 ,  1682 - 2  and, in the illustrated embodiment, the structural support volume  1646 - 1  surrounds the nonstructural panel  1680 - 1  in association with, or proximity to, the first and second pairs of opposed sides  1682 - 1 ,  1682 - 2 ,  1682 - 3 ,  1682 - 4 . In this embodiment, the structural support volume  1646 - 1  comprises a single continuous structural support volume substantially entirely surrounding the nonstructural panel  1680 - 1  to impart tension through both of the first and second pairs of opposed sides  1682 - 1 ,  1682 - 2 ,  1682 - 3 ,  1682 - 4 . When the structural support volume  1646 - 1  is expanded e.g., by inflation, it maintains the structural support volume portions generally designated  1646 - 1   a ,  1646 - 1   b  and  1646 - 1   c ,  1646 - 1   d  in spaced apart relation at a distance from one another thereby causing tension to be generated and maintained in the nonstructural panel  1680 - 1  as represented by the arrows  1699 - 1 ,  1699 - 2 . 
     In a practical embodiment of a disposable flexible container in accordance with the disclosure,  FIG. 1A  illustrates a flexible container  100  having a nonstructural (or flexible squeeze) panel  180 - 1  which at least partially defines the product volume  150 . The nonstructural panel  180 - 1  of the flexible container  100  will be seen to have at least one pair of opposed sides  182 - 1 ,  182 - 2 . The flexible container  100  also has a structural support volume  146 - 1  and  146 - 2  associated with, or in proximity to, each of the opposed sides  182 - 1 ,  182 - 2  of the nonstructural panel  180 - 1  in spaced apart relation at a distance from one another. 
     The nonstructural panel  180 - 1  will be understood to include a perimeter defined in  FIG. 1A  by the inner boundaries of structural support volumes or members  144 - 1 ,  146 - 1 ,  146 - 2 ,  148 - 1 , and one or more of the structural support volumes or members surround at least 50% of the nonstructural panel  180 - 1 , e.g., structural support members  146 - 1 ,  146 - 2 , in association with, or in proximity to, the perimeter of the nonstructural panel. In other embodiments contemplated in accordance with the disclosure, the structural support volume(s) surround at least about 60%, 70%, 80%, 90%, or all of the nonstructural panel  180 - 1  as specifically shown in  FIG. 1A , in association with, or in proximity to, the perimeter of the nonstructural (or squeeze) panel. 
     Still referring to  FIG. 1A , the nonstructural panel  180 - 1  preferably has first and second pairs of opposed sides  182 - 1 ,  182 - 2  and  184 - 1 ,  184 - 2 , respectively, and one or more structural support volumes, such as structural support members  146 - 1 ,  146 - 2 ,  148 - 1  surround the nonstructural panel in association with, or in proximity to, the first pair of opposed sides  182 - 1 ,  182 - 2  and at least one, e.g., side  184 - 1 , of the second pair of opposed sides  184 - 1 ,  184 - 2 . 
     In the illustrated embodiment, one or more structural support volumes, such as  144 - 1 ,  146 - 1 ,  146 - 2 ,  148 - 1 , substantially entirely surround the nonstructural panel  180 - 1  in association with, or in proximity to, the first and second pairs of opposed sides  182 - 1 ,  182 - 2 ,  184 - 1 ,  184 - 2  to impart tension to the nonstructural panel at least between one of the first and second pairs of opposed sides, e.g., sides  182 - 1 ,  182 - 2 . In this embodiment, the structural support volumes may comprise a first pair of opposed structural support volumes ( 146 - 1 ,  146 - 2 ) in association with, or in proximity to, the first pair of opposed sides  182 - 1 ,  182 - 2  of the nonstructural panel  180 - 1  to impart tension to the nonstructural panel and a second pair of opposed structural support volumes ( 144 - 1 ,  148 - 1 ) in association with, or in proximity to the second pair of opposed sides  184 - 1 ,  184 - 2  to maintain the first pair of structural support volumes ( 146 - 1 ,  146 - 2 ) in spaced relation a distance apart from one another. 
     In yet another embodiment, the structural support volume (represented in  FIG. 1A  as structural support volumes  144 - 1 ,  146 - 1 ,  146 - 2 ,  148 - 1 ) may comprise a single continuous structural support volume substantially entirely surrounding the nonstructural panel in proximity to the first and second pairs of opposed sides  182 - 1 ,  182 - 2 ,  184 - 1 ,  184 - 2  to impart tension through both of the first and second pairs of opposed sides of the nonstructural (or flexible squeeze) panel  180 - 1 . 
     In a further respect, and referring to  FIGS. 1A and 1B , the disposable flexible container  100  in accordance with the disclosure includes at least two flexible panels  180 - 1  and  180 - 2  wherein at least one, and preferably both, of the flexible panels  180 - 1 ,  180 - 2  are nonstructural panels which are opposed to one another for dispensing fluent product when they are squeeze toward one another. It will be noted that either or both of the nonstructural panels has opposed sides (such as the sides  182 - 1 ,  182 - 2  in the case of the panel  180 - 1 ), and a structural support volume, such as structural support members  146 - 1 ,  146 - 2 ,  146 - 3 ,  146 - 4 , is associated with each of the opposed sides (such as the sides  182 - 1 ,  182 - 2  of the panel  180 - 1 ) in the embodiment illustrated in  FIGS. 1A-1D .
