## Background
FIELD OF THE INVENTION
The present disclosure relates in general to containers, and in particular, to disposable flexible containers having surface elements thereon.
BACKGROUND OF THE INVENTION
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 OF THE INVENTION
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. 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 comprises a product volume for the fluent product at least partially defined by a nonstructural panel having one or more flat spaces and one or more structural support volumes. The disposable flexible container also includes one or more surface elements projecting outwardly in relation to the one or more flat spaces on the nonstructural panel. Preferably, the one or more structural support volumes comprise a structural support frame configured to prevent the container from collapsing and, more preferably, arranged to generate and maintain tension in the nonstructural panel when expanded.
In one embodiment, the nonstructural panel has a perimeter and the one or more structural support volumes surround about 50% of the perimeter and, preferably, about 75% of the perimeter of the nonstructural panel and, more preferably, about 100% of the perimeter of the nonstructural panel.
The one or more structural support volumes may suitably comprise a single continuous structural support volume bounding the perimeter of the nonstructural panel to define a structural support frame substantially surrounding the nonstructural panel, or the one or more structural support volumes may suitably comprise a first pair of opposed structural support volumes to generate and maintain tension in the nonstructural panel and a second pair of opposed structural support volumes to maintain the first pair of opposed structural support volumes a distance apart.
In another respect, the nonstructural panel may suitably comprise a squeeze panel formed of a flexible material wherein the product volume is at least partially between the squeeze panel and another panel also formed of a flexible material.
In one embodiment, the one or more surface elements may suitably comprise at least one nonstructural volume which defines a finger rest on the squeeze panel. In another embodiment, the one or more surface elements may suitably comprise a pattern of nonstructural volumes which projects outwardly of the one or more flat spaces on the squeeze panel. In a further embodiment, the one or more surface elements may suitably comprise a plurality of nonstructural volumes which serve to divide the squeeze panel into multiple nonstructural subpanels. In one embodiment, the surface elements are separate pieces non-integral to the container. In other embodiments the surface elements are separate pieces joined to the surface of the container.
It will be understood and appreciated that all of the foregoing features and aspects of disposable flexible containers having surface elements in accordance with the disclosure as well as all of the additional features and aspects described more fully below may be utilized in any of a variety of different combinations all contemplated to be within the scope of the disclosure.

DETAILED DESCRIPTION OF THE INVENTION
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 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. 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. 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 filling structure(s) in addition to one or more dispenser(s).
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 (cm2), or any integer value for cm2 between 1 and 50,000 cm2, or within any range formed by any of the preceding values, such as: from 2 to 25,000 cm2, 3 to 10,000 cm2, 4 to 5,000 cm2, 5 to 2,500 cm2, from 10 to 1,000 cm2, from 20 to 500 cm2, from 30 to 300 cm2, from 40 to 200 cm2, or from 50 to 100 cm2, 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 various embodiments, expansion materials can be added at atmospheric pressure, or added under pressure greater than atmospheric pressure, or added to provide a material change that will increase pressure to something above atmospheric pressure. For any of the embodiments of flexible containers, disclosed herein, its one or more flexible materials can be expanded at various points in time, with respect to its manufacture, sale, and use, including, for example: before or after its product volume(s) are filled with fluent product(s), before or after the flexible container is shipped to a seller, and before or after the flexible container is purchased by an end user.
As used herein, when referring to a product volume of a flexible container, the term “filled” refers to the state when the product volume contains an amount of fluent product(s) that is equal to a full capacity for the product volume, with an allowance for head space, under ambient conditions. As used herein, the term filled can be modified by using the term filled with a particular percentage value, wherein 100% filled represents the maximum capacity of the product volume.
As used herein, the term “flat” refers to a surface that is without significant projections or depressions.
As used herein, the term “flexible container” refers to a container configured to have a product volume, wherein one or more flexible materials form 50-100% of the overall surface area of the one or more materials that define the three-dimensional space of the product volume. For any of the embodiments of flexible containers, disclosed herein, in various embodiments, the flexible container can be configured to have a product volume, wherein one or more flexible materials form a particular percentage of the overall area of the one or more materials that define the three-dimensional space, and the particular percentage is any integer value for percentage between 50% and 100%, or within any range formed by any of these values, such as: 60-100%, or 70-100%, or 80-100%, or 90-100%, etc. One kind of flexible container is a film-based container, which is a flexible container made from one or more flexible materials, which include a film.
For any of the embodiments of flexible containers, disclosed herein, in various embodiments, the middle of the flexible container (apart from any fluent product) can be configured to have an overall middle mass, wherein one or more flexible materials form a particular percentage of the overall middle mass, and the particular percentage is any integer value for percentage between 50% and 100%, or within any range formed by any of the preceding values, such as: 60-100%, or 70-100%, or 80-100%, or 90-100%, etc.
For any of the embodiments of flexible containers, disclosed herein, in various embodiments, the entire flexible container (apart from any fluent product) can be configured to have an overall mass, wherein one or more flexible materials form a particular percentage of the overall mass, and the particular percentage is any integer value for percentage between 50% and 100%, or within any range formed by any of the preceding values, such as: 60-100%, or 70-100%, or 80-100%, or 90-100%, etc.
As used herein, when referring to a flexible container, the term “flexible material” refers to a thin, easily deformable, sheet-like material, having a flexibility factor within the range of 1,000-2,500,000 N/m.

The structural support members define a triangular shaped top panel 1080-t, and a triangular shaped bottom panel (not shown). The top panel 1080-t and the bottom panel are about flat, however in various embodiments, part, parts, or all of any of the side panels can be approximately flat, substantially flat, nearly flat, or completely flat. The container 1000 includes a dispenser 1060, which is configured to dispense one or more fluent products from one or more product volumes disposed within the container 1000. In the embodiment of FIG. 10A, the dispenser 1060 is disposed in the center of the front, however, in various alternate embodiments, the dispenser 1060 can be disposed anywhere else on the top, sides, or bottom, of the container 1000. FIG. 10A includes exemplary additional/alternate locations for a dispenser (shown as phantom lines). 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 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 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. FIG. 11A includes exemplary additional/alternate locations for a dispenser (shown as phantom lines). FIG. 11B illustrates an end view of the flexible container 1100 of FIG. 10B, resting on a horizontal support surface 1101.
In additional embodiments, any self-supporting 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. For example, any self-supporting container with a structural support frame, as disclosed herein, can be configured to have an overall shape (when observed from a top view) that corresponds with a rectangle, a polygon (having any number of sides), an oval, an ellipse, a star, or any other shape, or combinations of any of these.

Referring to FIG. 15, a disposable flexible container 1500 comprises a product volume 1550 for a fluent product at least partially defined by a nonstructural panel 1580-1 having one or more flat spaces such as 1581-1a and 1581-1b and one or more structural support volumes such as 1544-1, 1546-1, 1546-2 and 1548-1. The disposable flexible container 1500 also includes one or more surface elements such as 1547a projecting outwardly in relation to the one or more flat spaces such as 1581-1a and 1581-1b on the nonstructural panel 1580-1. Preferably, the one or more structural support volumes such as 1544-1, 1546-1, 1546-2 and 1548-1 comprise a structural support frame generally designated 1549 configured to prevent the container 1500 from collapsing and arranged to generate and maintain tension in the nonstructural panel 1580-1 when expanded.
In order to understand the manner in which tension can be generated and maintained in a nonstructural panel such as 1580-1, it is instructive to refer to FIGS. 17A-17F which illustrate the principle behind utilizing structural support volumes.
Referring to FIG. 17A, a nonstructural panel 1780-1 has opposed fixed sides 1782-1, 1782-2 and the structural support volume 1746-1 is disposed at a point intermediate the fixed sides 1782-1, 1782-2 of the nonstructural panel 1780-1. When the structural support volume 1746-1 is expanded, e.g., by inflation, tension is generated and maintained in the nonstructural panel 1780-1 represented by the arrows 1799-1 and 1799-2 on either side of the structural support volume 1746-1.
Referring next to FIG. 17B, the nonstructural panel 1780-1 has opposed fixed sides 1782-1, 1782-2 and the structural support volume 1746-1 is associated with one of the fixed sides, i.e., fixed side 1782-1, of the nonstructural panel 1780-1. When the structural support volume 1746-1 is expanded, tension is generated and maintained in the nonstructural panel 1780-1 represented by the arrow 1799-1 on the panel side of the structural support volume 1746-1.
Referring to FIG. 17C, the nonstructural panel 1780-1 has opposed fixed sides 1782-1, 1782-2 and one of the structural support volumes 1746-1, 1746-2 is associated with each of the fixed sides 1782-1, 1782-1 of the nonstructural panel 1780-1. When the structural support volumes 1746-1, 1746-2 are expanded, tension is generated and maintained in the nonstructural panel 1780-1 as represented by the arrow 1799-1 between the structural support volumes 1746-1, 1746-2. The two structural support volumes are at a separation distance of L from each other as indicated.
In the embodiment of FIG. 17C, it will be appreciated that the nonstructural panel 1780-1 has a perimeter and the one or more structural support volumes i.e., the structural support volumes 1746-1, 1746-2, surround about 50% of the perimeter of the nonstructural panel 1780-1.
Referring next to FIG. 17D, the nonstructural panel 1780-1 includes a perimeter which, as illustrated, has opposed fixed sides 1782-1, 1782-2 and the structural support volume 1746-1 surrounds more than 50% of the nonstructural panel 1780-1 in association with, or proximity to, the perimeter of the nonstructural panel 1780-1. More specifically, and still referring to FIG. 17D, the nonstructural panel 1780-1 includes first and second pairs of opposed sides and, in particular, opposed fixed sides 1782-1, 1782-2 as well as opposed sides 1782-3, 1782-4 extending between opposed fixed sides 1782-1, 1782-2. In the illustrated embodiment, the structural support volume 1746-1 surrounds the nonstructural panel 1780-1 in association with, or proximity to, the first pair of opposed fixed sides 1782-1, 1782-2 and at least one of the second pair of opposed sides 1782-3.
When the structural support volume 1746-1 is expanded, tension is generated and maintained in the nonstructural panel 1780-1 as represented by the arrows 1799-1, 1799-2 between the structural support volume portions 1746-1a, 1741-1b. Thus, in the embodiment of FIG. 17D, the nonstructural panel 1780-1 has a perimeter and the one or more structural support volumes i.e., the structural support volume 1746-1, surrounds about 75% of the perimeter of the nonstructural panel 1780-1.
However, in still other embodiments, the nonstructural panel 1780-1 has a perimeter wherein the one or more structural support volumes surround about 100% of the perimeter of the nonstructural panel 1780-1 (see, e.g., FIGS. 17E and 17F).
Referring to FIG. 17E, the nonstructural panel 1780-1 includes first and second pairs of opposed sides and, in particular, opposed sides 1782-1, 1782-2 as well as opposed sides 1782-3, 1782-4 extending between opposed sides 1782-1, 1782-2 and, in the illustrated embodiment, the structural support volumes 1746-1, 1746-2 and 1744-1, 1748-1 surround the nonstructural panel 1780-1 in association with, or proximity to, the first and second pairs of opposed sides 1782-1, 1782-2, and 1782-3, 1782-4, respectively. In this embodiment, the structural support volumes 1746-1, 1746-2 and 1744-1, 1748-1 comprise a first pair of opposed structural support volumes (1746-1, 1746-2) in proximity to the first pair of opposed sides 1782-1, 1782-2 to impart tension to the nonstructural panel 1780-1 and a second pair of opposed structural support volumes (1744-1, 1748-1) in proximity to the second pair of opposed sides 1782-3, 1782-4 to maintain the first pair of opposed structural support volumes (1746-1, 1746-2) a distance apart. Thus, when all of the structural support volumes 1746-1, 1746-2, and 1744-1, 1748-1 are expanded, the structural support volumes 1744-1, 1748-1 maintain the opposed structural support volumes 1746-1, 1746-2 in spaced apart relation at a distance from one another, and the corresponding structural support volumes 1746-1, 1746-2 and 1744-1, 1748-1 cause tension to be generated and maintained in the nonstructural panel 1780-1 in perpendicular directions as represented by the arrows 1799-1 and 1799-2, respectively, in FIG. 17E.
Referring to FIG. 17F, the nonstructural panel 1780-1 includes first and second pairs of opposed sides and, in particular, opposed sides 1782-1, 1782-2 as well as opposed sides 1782-3, 1782-4 extending between opposed sides 1782-1, 1782-2 and, in the illustrated embodiment, the single continuous structural support volume substantially entirely surrounds the nonstructural panel 1780-1 in association with, or proximity to, the first and second pairs of opposed sides 1782-1, 1782-2, 1782-3, 1782-4. Thus, in this embodiment, the structural support volume comprises a single continuous structural support volume substantially entirely surrounding the nonstructural panel 1780-1 to impart tension through both of the first and second pairs of opposed sides 1782-1, 1782-2, 1782-3, 1782-4. When the structural support volume is expanded e.g., by inflation, it maintains structural support volume portions 1746-1, 1746-2, 1744-1, 1748-1 in spaced apart relation at a distance from one another thereby causing tension to be generated and maintained in the nonstructural panel 1780-1 as represented by the arrows 1799-1, 1799-2.
In the embodiments of FIGS. 17E and 17F, it will be appreciated that the structural support volumes or volume portions 1746-1, 1746-2, 1744-1, 1748-1 correspond generally to the structural support volumes 146-1, 146-2, 144-1, 148-1 in FIGS. 1A-1D.
In a practical embodiment of a disposable flexible container in accordance with the disclosure, the disposable flexible container 1500 of FIG. 15 is substantially similar to the disposable flexible container 100 of FIG. 1A. However, this embodiment has one or more surface elements such as 1547a projecting outwardly in relation to the one or more flat spaces such as 1581-1a and 1581-1b on the nonstructural panel 1580-1. In other respects, the disposable flexible containers 100 and 1500 may be identical, or may differ, e.g., by having the dispenser 1560 at the bottom of the container 1500 unlike the dispenser 160 which is at the top of the container 100.
Referring specifically to FIG. 15, the nonstructural panel 1580-1 may suitably comprise a squeeze panel formed of a flexible material wherein the product volume 1550 is at least partially between the squeeze panel 1580-1 and another panel such as 180-2 in FIGS. 1B and 1C also formed of a flexible material that may be the same as or different from the flexible material of the squeeze panel. The one or more surface elements such as 1547a may suitably comprise at least one nonstructural volume (see, also, FIG. 16) to define a flat space comprising a finger rest as at 1581-1b on the squeeze panel 1580-1. In particular, a finger rest is to be understood as referring to a configuration comprising an area defined by one or more recesses and/or one or more protrusions that serve to i) locate, ii) constrain movement of, and/or iii) aid in gripping by any one or more of the digits on the human hand In the embodiment of FIG. 16, the finger rest 1581-1b defined by the at least one nonstructural volume is generally circular in shape, and a nonstructural volume 1547b extends between the nonstructural volume 1547a and the structural support volume 1548-1 to facilitate fluid communication between the two of them. However, it will be understood that a finger rest in accordance with the disclosure can take any of a wide variety of different configurations that provide a designated area or areas on a nonstructural panel for one or more of the digits on the human hand including the first finger, middle finger, ring finger, pinky finger or thumb.
Referring to FIG. 18, the one or more surface elements 1547a, 1547b, 1547c, etc. may suitably comprise a pattern of nonstructural volumes which project outwardly of the one or more flat spaces 1581-1a, 1581,1b, 1581-1c, etc. on the squeeze panel 1580-1 and, while shown in FIG. 18 as a regular pattern, it will be understood and appreciated that the pattern of nonstructural volumes on the squeeze panel 1580-1 may comprise any desired regular or irregular pattern wherein the nonstructural volumes have any desired shape(s) and/or size(s).
Referring to FIG. 19, the one or more surface elements 1547a, 1547b, etc. may suitably comprise a plurality of nonstructural volumes which serve to divide the squeeze panel 1580-1 into multiple nonstructural subpanels or flat spaces 1581-1a, 1581-1b, 1581-1c, etc. and, while shown in FIG. 19 as linear angled nonstructural volumes, it will be understood that the surface elements such as 1547a, 1547b, etc. may have any desired shape(s) and/or arrangement(s) and/or size(s).
Referring to FIG. 16, the nonstructural panel 1580-1 may comprise first and second layers 1580-1a, 1580-1b defining a double wall wherein one or more heat seals join the first and second layers at discrete locations such as 1583-1, 1583-2, 1583-3, 1583-4, 1583-5. While heat seals may be used, it will also be understood that the first and second layers defining the double wall can be joined or bonded where needed by any other known manner of joining two flexible materials together. The heat seals form at least one or more structural support volumes such as 1546-1 and 1546-2 as well as one or more nonstructural volumes such as 1547a comprising the one or more surface elements of the container 1500 between the first and second layers 1580-1a, 1580-1b. 
With regard to the one or more nonstructural volumes such as 1547a, it has been illustrated as an expanded nonstructural volume, i.e., a volume which has been expanded by a gas such as vaporized liquid nitrogen; however, it may comprise a material-filled nonstructural volume, i.e., a volume filled or otherwise defined by a liquid or solid material or element rather than a gas.
As shown in FIG. 16, the heat seals may either be quite narrow (see, e.g., the discrete locations 1583-1 and 1583-5) or they can bond a substantial area of the first and second layers 1580-1a, 1580-1b together (see, e.g., the discrete locations designated 1583-2, 1583-3, 1583-4), although, it is preferred to utilize narrow heat seals on opposite sides of each of the discrete locations 1583-2, 1583-3, 1583-4 since there is no need to seal the first and second layers 1580-1a, 1580-1b together throughout the entirety of the areas occupied by the structural support volumes and the surface elements.
Referring to FIGS. 16 and 20, it will be appreciated that the structural support volumes such as 1544-1, 1546-1, 1546-2, 1548-1 (and, as specifically shown in FIG. 20, the structural support volume 1548-1) each comprise a measurable volume when expanded, e.g., by inflating them with evaporated liquid nitrogen. One or more of the structural support volumes (e.g., the structural support volume 1548-1 in FIG. 20) also may include one or more heat seals such as 1585-1, 1585-2, 1585-3, 1585-4 bonding the double walls defined by the first and second layers 1580-1a, 1580-1b together. In this manner, the heat seals such as 1585-1, 1585-2, 1585.3, 1585-4 in FIG. 20, may reduce from about 0.1% to about 50% of the measurable volume and, preferably, from about 1% to about 40% of the measurable volume and, more preferably, from about 2% to about 35% of the measurable volume.
With regard to FIGS. 15, 18 and 19, the one or more surface elements on the nonstructural panel 1580-1 such as 1547a, 1547b in FIG. 15, 1547a, 1547b, 1547c, etc. in FIG. 18 and 1547a, 1547b, etc. in FIG. 19, or any other type, arrangement and size of similar surface elements in other embodiments, may comprise about 1% to about 100% or, preferably, about 1% to about 75%, or, more preferably, about 1% to about 50% or, still more preferably, about 1% to about 25% or, even more preferably, about 1% to about 10% of a total area defined by the nonstructural panel.
Also, with regard to FIGS. 15, 18 and 19, there is a ratio of area comprising the one or more surface elements such as 1547a, 1547b in FIG. 15, 1547a, 1547b, 1547c, etc. in FIG. 18 and 1547a, 1547b, etc. in FIG. 19 on the nonstructural panel 1580-1. Further, there is an area comprising the one or more flat spaces such as 1581-1a and 1581-1b in FIG. 15, 1581-1a, 1581-1b, 1581-1c, etc. in FIG. 18 and 1581-a, 1581-1b, 1581-1c, etc. in FIG. 19 on the nonstructural panel 1580-1. The ratio of area comprising the one or more surface elements to area comprising the one or more flat spaces is about 0.006 to about 115 and, preferably, about 0.01 to about 50 and, more preferably, about 0.07 to about 10.
Again referring to FIGS. 15, 18 and 19, the surface elements, such as 1547a, 1547b in FIG. 15, 1547a, 1547b, 1547c, etc. in FIG. 18 and 1547a, 1547b, etc. in FIG. 19, locally extend out in a direction substantially normal to the flat spaces, such as 1581-1a and 1581-1b in FIG. 15, 1581-1a, 1581-1b, 1581-1c, etc. in FIG. 18 and 1581-a, 1581-1b, 1581-1c, etc. in FIG. 19 on the nonstructural panel 1580-1, to a height or distance that is at least about 1 micrometer (μm) or any integer value for micrometers from about 1 to about 30,000 micrometers (μm).
Preferably, the surface elements in FIGS. 15, 18 and 19, or in any other embodiment in accordance with the disclosure, locally extend out in a direction normal to the flat spaces on the nonstructural panel to a height or distance that is in the range of about 100 to about 5,000 micrometers (μm), and more preferably, in the range of about 500 to about 1,000 micrometers (μm),
With regard to all such surface elements, it is to be understood that are elements that are elements that are at least about 50% to about 100% surrounded by a flat space or spaces on a nonstructural panel but exclude applied surface features such as labels and shaped structures and the height or distance they locally extend is measured in a direction normal to the flat space substantially adjacent the surface element to the highest point of the surface element at any location along its length.
Still referring to FIGS. 15, 18 and 19, the disposable flexible container 1500 of any of these embodiments, or any other embodiments according to the disclosure including, but not limited to, FIGS. 1A-1D, may comprise a stand-up container. These embodiments will typically have a top end (e.g., 104 in FIGS. 1A-1B), a bottom end (e.g., 108 in FIGS. 1A-1B), and a left side and a right sides (e.g., 109 in FIGS. 1A-1B), In addition, these embodiments will typically include a base structure (e.g., 190 in FIGS. 1A-1B) for resting the bottom end 108 on any horizontal support surface so that it can stand upright as shown, e.g., in FIGS. 1A-1B, 15, 18 and 19-20.
As will be appreciated from FIGS. 15, 18 and 19, the nonstructural panel 1580-1 may have at least some irregular cross-sections when taken generally perpendicular to an outwardly facing surface of the nonstructural panel in a direction from the left side to the right side of the containers 1500 at various different points between the top end and the bottom end of the container and, as will also be appreciated from FIGS. 15, 18 and 19, the nonstructural panel 1580-1 may have at least some irregular cross-sections when taken generally perpendicular to an outwardly facing surface of the nonstructural panel in a direction from the top end to the bottom end of the containers 1500 at various different points between the left side and the right side of the container.
In all of the foregoing embodiments, the one or more structural support volumes such as 1544-1, 1546-1, 1546-2, 1548-1 will be seen to at least partially bound the one or more nonstructural volumes such as 1547a, 1547b in FIG. 15, 1547a, 1547b, 1547c, etc. in FIG. 18 and 1547a, 1547b, etc. in FIG. 19. Because the one or more structural support volumes at least partially bound the one or more nonstructural volumes, the containers 1500 are rendered substantially self-supporting independent of the one or more nonstructural volumes. Also, the containers 1500 each have a shape substantially defined by the one or more structural support volumes, and the containers have an outer surface texture defined at least in part by the one or more nonstructural volumes.
With regard to all embodiments, none of the one or more structural support volumes such as 1544-1, 1546-1, 1546-2, 1548-1 need be in fluid communication with any of the one or more nonstructural volumes such as 1547a, 1547b in FIG. 15, 1547a, 1547b, 1547c, etc. in FIG. 18 and 1547a, 1547b, etc. in FIG. 19.
As an alternative, at least one of the one or more structural support volumes such as 1544-1, 1546-1, 1546-2, 1548-1 may be in fluid communication with at least one of the one or more nonstructural volumes such as 1547a, 1547b in FIG. 15, 1547a, 1547b, 1547c, etc. in FIG. 18 and 1547a, 1547b, etc. in FIG. 19.
As a still further alternative, some or all of the one or more structural support volumes such as 1544-1, 1546-1, 1546-2, 1548-1 may be in fluid communication with some or all of the one or more nonstructural volumes such as 1547a, 1547b in FIG. 15, 1547a, 1547b, 1547c, etc. in FIG. 18 and 1547a, 1547b, etc. in FIG. 19.
In any embodiments, printed text may be present along with 3D surface elements. The text may appear on the inner or outer surface of any layer present. Due to the 3D relief of the 3D surface elements present, this can present challenges for the legibility of the text when reading from a fixed position and/or when viewing the package from a distance, such as for example, on a store shelf or in a vending machine.
Referring to FIG. 18, the nonstructural panel 1580-1 may have a printed text as at 1587 comprising a font or a language system of characters and/or numbers wherein the characters present have an average height measurement designated as “t”. The average height “t” is an average of all of the characters present and is measured from the upper most extent of the character to the lowermost extent of the character. The nonstructural volume has a characteristic dimension “d” measured from border region to border region of the nonstructural volume in the direction of the printed text, e.g., as shown in FIG. 18. The dimensionless ratio t/d can be called the legibility ratio and, for some embodiments, can be in the range of about 0.01 to about 50, more preferably about 0.03 to about 10, still more preferably, about 0.1 to about 1.
The container 1500 in FIG. 18 will be seen to have a first (left) side 1509 and a second (right) side 1509 so the average height “t” can be determined by measuring the vertical height of all of the characters present when the printed text extends in a direction running generally from the first (left) toward the second (right) side, or vice versa, i.e., if the printed text runs generally horizontally. Alternatively, the container 1500 will also be seen to have a top end 1504 and a bottom end 1508 so the average height “t” can be determined by measuring the vertical height of all of the characters present when the printed text extends in a direction running generally from the top end toward the bottom end, or vice versa, if the printed text runs generally vertically. In either of these cases, the width dimension “d” of the nonstructural volume(s) in the region of printed text can be measured in the direction the printed text runs, i.e., horizontally when the printed text runs horizontally as shown in FIG. 18, and vertically when the printed text runs vertically which can be called the parallel legibility ratio. Alternatively, the width dimension “d” of the nonstructural volume(s) in the region of printed text can be measured perpendicular to the direction the printed text runs, i.e., vertically when the printed text runs horizontally as shown in FIG. 18, and horizontally when the printed text runs vertically which can be called the perpendicular legibility ratio.
Referring once again to FIGS. 15 and 16 as being illustrative, another feature of the disclosure is that the one or more structural support volumes such as 1546-1, 1546-2 at least partially bounding the one or more nonstructural volumes such as 1547a project outwardly further from the one or more flat spaces such as 1581-1a, 1581-1b on the nonstructural panel 1580-1 than the one or more nonstructural volumes.
In another respect, it will also be appreciated from FIG. 16 that the one or more structural support volumes such as 1546-1, 1546-2 and the one or more nonstructural volumes such as 1547a each have a measurable expanded volume.
