Nothing in this specification should be construed as requiring a specific three dimensional orientation of structures in order to fall within the scope of these disclosures. Also, the reader is advised that the attached drawings are not necessarily drawn to scale.
In general, aspects of this disclosure relate to systems and methods for production of an insulating container, or device, that may have one or more vacuum insulated panels. According to various aspects and embodiments, the insulating container may be formed of one or more of a variety of materials, such as metals (including metal alloys), plastics, polymers, and composites, and may be formed in one of a variety of configurations, without departing from the scope of these disclosures.
The various figures in this application illustrate examples of insulating containers/structures according to this disclosure. When the same reference number appears in more than one drawing, that reference number is used consistently in this specification and the drawings refer to the same or similar parts throughout.
FIG. 1 depicts an isometric view of one example of an insulating container 100, according to one or more aspects described herein. In particular, the insulating container 100 may be described as a “cooler” device, having a lid insulating structure 102 with a lid upper face 106 and a base insulating structure 104 that includes side insulating structures 475 (see FIGS. 4B, 4C) with respective side outer faces 108a, 108b, 108c, 108d (see also FIG. 4A) and a bottom insulating structure 465 with bottom outer face 455 (see FIGS. 4B, 4C). Lid insulating structure 102, when closed, together with base insulating structure 104, including side insulating structures 475 and bottom insulating structure 465, enclose an internal storage compartment 445 (see FIGS. 4A-C). In one example, the insulating container 100 may be configured, by virtue of various features of lid insulating structure 102, side insulating structures 475, and bottom insulating structure 465, discussed in greater detail below, to reduce a rate of heat transfer to/from internal storage compartment 445. In one example, lid insulating structure 102 may be hinged (e.g., along respective mating edges 105, 107 of lid insulating structure 102 and base insulating structure 104) relative to base insulating structure 104 to either enclose or allow access to internal storage compartment 445.
The insulating container 100 may have one or more structural elements configured to increase a thermal resistance of the container 100. As such, the insulating container 100, or elements of the insulating container, may be molded from one or more polymers, for example using a rotational molding (rotomolding) process. In this way, load-bearing structures of the insulating container 100 may be formed from one or more molded polymers. In one example, utilizing one or more polymers to form the structural elements of the insulating container 100 may offer the advantage of comparatively higher thermal resistivity properties exhibited by polymers, when compared to, for example, metals or alloys. Any of lid insulating structure 102 and base insulating structure 104, including side insulating structures 475 and bottom insulating structure 465, may be molded from one type of polymer, from different types of polymers in different regions (e.g., in the case of discreet polymer layers), or from blends of different polymers (e.g., in the case of homogeneously distributed polymers). Likewise, any elements (e.g., inner, outer, top, and bottom walls) of insulating structure 102 and base insulating structure 104, including side insulating structures 475 and bottom insulating structure 465, as described in greater detail below, may be molded from one type of polymer, from different types of polymers in different regions (e.g., in the case of discreet polymer layers), or from blends of different polymers (e.g., in the case of homogeneously distributed polymers).
In one implementation, the insulating container 100 may represent one example of a device that may be utilized with the systems and methods described herein in order to achieve improved thermal resistance. As such, the dimensions of insulating container 100, in addition to the various depicted geometrical features of insulating container 100 are not specific. Systems and methods described herein may be utilized with any insulating device structure that has one or more internal cavities configured to be partially or wholly filled with an additional insulating material.
FIGS. 2A-2C schematically depict an insulating component 201 that may be used in conjunction with any one of, any combination of, or all of, lid insulating structure 102, and base insulating structure 104, including side insulating structures 475 and bottom insulating structure 465. The use of one, some, or all of these insulating structures in conjunction with insulating component 201 refers to this component being internal to an insulating structure or otherwise the insulating structure having a surface comprising, or being coextensive with, all or a portion of a surface of insulating component 201, as described in greater detail below. FIG. 2A depicts an exploded view of elements of insulating component 201 and FIG. 2B depicts a cross-sectional view of assembled elements of insulating component 201 shown in FIG. 2A. In one example, the insulating component 201 may be utilized with the systems and methods described herein for achieving improved thermal resistance. The insulating component 201 may be used in lid insulating structure 102 of insulating container 100 shown in FIG. 1.
In one example, as shown in FIGS. 2A-2C, insulating component 201 may include a retaining portion 205, a cover portion 224, and an insulating portion 615 disposed between retaining portion 205 and cover portion 224. Retaining portion 205 may include four side walls 210, and a bottom wall 212, which form a cavity 214. Side walls 210 and bottom wall 212 may form respective retaining portion outer surfaces 211 and retaining portion bottom surface 213 (see FIG. 2C). In one specific example, and similar to insulating container 100 as a whole, insulating component 201, or any of its elements, may be molded from polyethylene. In another example, insulating component 201, or any of its elements, may be molded from polyurethane. In some embodiments, all elements of insulating component 201 may be molded from the same type of polymer. In other embodiments, different elements of insulating component 201 may be molded from different polymers.
As discussed in more detail below, the insulating portion 615 may comprise one or more vacuum insulated panels 625, for example in any of the configurations shown in FIGS. 5A-5H and discussed in greater detail below. Insulating portion 615 may be sized to fit within the cavity 214, such that it may be contained in insulating component 201. Additionally or alternatively, the insulating portion 615 may comprise a mass of insulating foam that partially or wholly fills a cavity within the insulating portion 615.
As shown in FIGS. 2A-2C, cover portion 224 may be disposed over insulating portion 615 and may secure insulating portion 615 within cavity 214. In some embodiments, cover portion 224 may correspond with the upper face of the lid 106. Insulating portion 615 may also be secured within cavity 214 using, as an alternative to, or in addition to, cover portion 224, adhesives, tape, or other devices. As shown in FIG. 2B, cover portion 224 may abut, and/or be bonded to, an inner surface 216 of retaining portion 205 (e.g., corresponding to an inner surface of side wall 210). In other embodiments, as shown for example in FIG. 2C, cover portion 224 may abut, and/or be bonded to top surface 218 of retaining portion 205 (e.g., corresponding to a top surface of side wall 210). In the case of cover portion 224 abutting inner surface 216, a cover portion top surface 207 (see FIG. 2C) and top surface 218 of retaining portion 205 (or side wall 210 thereof) may be substantially co-planar. In the case of cover portion 224 abutting top surface 218, a cover portion side surface 209 and an outer surface 211 of retaining portion 205 (or side wall 210 thereof) may be substantially co-planar. As shown with dashed lines on the left-hand side of FIG. 2C, cover portion 224 may abut both inner surface 216 and top surface 218 of retaining portion 205 (or side wall 210 thereof).
Cover portion 224 may be fastened to retaining portion 205 by any means suitable, including for example, using chemical bonding agents including adhesives, using mechanical fasteners including screws, rivets or interference fittings, and/or using thermal bonding (e.g., by melting) with or without a separate bonding agent such as a low melting point polymer. For example, cover portion 224 may be attached to retaining portion 205 by welding or plastic welding cover portion 224 to retaining portion 205. In some examples, engagement between cover portion and retaining portion 205 may provide a watertight seal, advantageously preventing liquids from entering cavity 214 and/or insulating portion 615 which may reduce the efficiency of the insulating portion 615 and overall performance of insulating container 100. In one specific example, this seal may include a gasket element that extends around a perimeter of the cover portion 224. It is contemplated that any gasket design (c-shaped gasket, among others) may be utilized, without departing from the scope of these disclosures. In one implementation, a coupling between a cover portion 224 and a retaining portion 205 may be rigid, or may be removable, without departing from the scope of these disclosures.
Cover portion 224 may be manufactured of any suitable material. In some examples cover portion 224 may be manufactured of metals such as stainless steel, plastics, and composites including, for example, carbon fiber. In some examples, cover portion 224 and retaining portion 205 may be molded, for example, through rotomolding, as a single piece and in other examples cover portion 224 and retaining portion 205 may be molded as separate pieces. In some examples, insulating portion 615 may be included within cavity 214 of insulating component 201 during the molding, for example rotomolding, process. In still other examples, cover portion 224 and retaining portion 205 may be molded as a single piece without insulating portion 615 included within cavity 214. In such a process, cover portion 224 may be removed, for example, by cutting, allowing insulating portion 615 to be inserted into cavity 214, followed by re-engagement of cover portion 224 with retaining portion 205 as discussed above.
As shown in FIGS. 3A and 3B, retaining portion 305, cover portion 324, and insulating portion 615 may have other configurations and/or geometries. FIGS. 3A and 3B schematically depict cross-sections of alternative embodiments of insulating component 201. As described above, any of, any combination of, or all of, lid insulating structure 102 and base insulating structure 104, including side insulating structures 475 and bottom insulating structure 465, or portions thereof, may include insulating component 201, or otherwise have a face in common with (comprising or coextensive with) a surface of insulating component 201, according to representative insulating containers as described herein, including insulating container 100 as depicted in FIG. 1. For example, an outer face 108a, 108b, 108c, 108d of side insulating structure 475 may comprise or may be coextensive with a surface of insulating component 201. According to more particular embodiments, any of, or any portion of, (i) lid upper face 106 of lid insulating structure 102, (ii) outer faces 108a, 108b, 108c, 108d of side insulating structures 475, and/or (iii) bottom outer face 455 of bottom insulating structure 465 may comprise, or be coextensive with, all or a portion of cover portion top surface 207, cover portion side surface 209, retaining portion outer surface 211, or retaining portion bottom surface 213. According to other embodiments, insulating component 201 may be contained entirely within any of, any combination of, or all of, lid insulating structure 102 and base insulating structure 104, including side insulating structures 475 and bottom insulating structure 465.
In one example, as shown in FIG. 3A, insulating component 201 may include retaining portion 305, cover portion 324, and insulating portion 615 disposed within retaining portion 305 and cover portion 324. Retaining portion 205 may include side walls 310 and bottom wall 312, which form cavity 214 as illustrated in FIG. 2A.
As described above, insulating portion 615 may be sized to fit within cavity 214, and as discussed in more detail below, insulating portion 615 may comprise one or more vacuum insulated panels 625.
As shown in FIG. 3A, cover portion 324 may be engaged with retaining portion 305 to secure insulating portion 615 within cavity 214. As shown for example in FIG. 3B, cover portion 324 may engage inner surfaces 316 of retaining portion 305. As shown in FIG. 3A cover portion 324 may intersect top surfaces 318 of retaining portion 305.
As described above, cover portion 324 may be engaged/attached to the retaining portion 305 by any means suitable, including for example, using chemical bonding agents including adhesives, using mechanical fasteners including screws, welding and/or using thermal bonding (e.g., by melting) with or without a separate bonding agent such as low melting point polymer. In some examples, the portion 324 may be engaged with retaining portion 305 such that a watertight seal, or even an airtight seal, is created. This can advantageously prevent liquids from reaching cavity 214 and/or insulating portion 615 which may reduce the efficiency of insulating portion 615 and insulating container 100 in general.
In some embodiments, the insulating component 201 may include one or more gaskets 321, for example to form or improve a seal between cover portion 324 and retaining portion top surfaces 318, as shown in FIG. 3A or between cover portion 324 and retaining portion inner surfaces 316, as shown in FIG. 3B. In some embodiments, insulating component 201 may include one or more gaskets 321 engaged between retaining portion 305 and cover portion 324 at any abutting surfaces. Such configurations may reduce thermal conductivity between retaining portion 305 and cover portion 324 and may create a watertight, and possibly airtight, seal between retaining portion 305 and cover portion 324. In some embodiments, gaskets 321 may impart both functional and aesthetic enhancements, for example by being installed such that the seam between retaining portion 305 and cover portion 324 is concealed by the one or more gaskets 321. Additionally, in some embodiments fastening members used to fasten retaining portion 305 to cover portion 324 may be concealed by the one or more gaskets 321.
In some embodiments, portions of insulating component 201 including retaining portion 205, 305 and cover portion 224, 324 may optionally include one or more hollow portions. For example, possible hollow portions 351 in side walls 310 or bottom wall 312 of retaining portion 305 or in cover portion 324 are depicted using dashed lines in FIG. 3B. Elements of insulating component 201, including side walls 310 and/or bottom wall 312 of retaining portion 305 and/or cover portion 324 may have a thickness dimension T (or possibly a minimum thickness dimension T if the thickness is not constant) generally in the range of about 0.05 in. to about 0.25 in., with a representative thickness dimension T being about 0.15 inches. One or more hollow portions 351 may be configured to be, or may be, at least partially filled with an insulating material. Likewise, one or more, or all, cavities 214 may be configured to be, or may be, at least partially filled with an insulating material, in which case such insulating material is namely the insulating portion 615. In one example, the insulating material may comprise a polymeric foam, such as a polyurethane foam. However, in another example, additional or alternative insulating materials may be utilized to fill one or more hollow portions 351, or one or more cavities 214, without departing from the scope of the disclosures described herein. For example, one or more hollow portions 351 may be configured to be, or may be, at least partially filled with an alternative polymeric foam, such as polystyrene foam, polyvinyl chloride foam, or polyimide foam, among many others. As such, in one example, a polymer or polymer blend that is used to mold one or more, or all, elements of the insulating component 201, including side walls 310 and/or bottom wall 312 of retaining portion 305 and/or cover portion 324, may have a first thermal resistivity, and an insulating material used to at least partially fill one or more hollow portions 351 and/or one or more cavities 214 may have a second thermal resistivity, higher than the polymer or polymer blend. In yet another implementation, one or more hollow portions 351 and/or one or more cavities 214 may be configured to be, or may be, at least partially filled with a second insulating material that adheres to one or more molded polymeric surfaces of the hollow portion(s) and/or the cavity(ies). The second insulating material may also adhere the insulating material to these molded polymeric surfaces or may adhere the insulating material to itself (i.e., act as a binder for the insulating material). For example, a mix of polymer flakes, or pellets, in addition to a second insulating material that is namely a binder may be injected into one or more hollow portions 351, one or more cavities 214, or any combination thereof.
In one example, one or more hollow portions 351 and/or one or more cavities 214, or any combination thereof, may be partially filled with an insulating material as described above, such as an insulating foam (polyurethane foam). Partially filling the hollow portion(s) and/or cavity(ies) may refer to injecting, or otherwise providing, insulating foam such that the hollow portion(s) 351 and/or cavity(ies) 214 may be at least about 50% filled, at least about 80% filled, at least about 85% filled, at least about 90% filled, at least about 95% filled, at least about 97% filled, at least about 99% filled, at least about 99.7% filled, or at least about 99.9% filled, with the percentage filled meaning the total volume, in bulk form, of the insulating material and any second insulating material, divided by the volume of the hollow portion 351 or cavity 214.
In still other examples, insulating component 201, when used in conjunction with one of, some of, or all of, lid insulating structure 102 and base insulating structure 204, including side insulating structures 475 and bottom insulating structure 465, may forego the use of insulating portion 615, such that cavity 214 of insulating component 201, surrounded by retaining portion 205 and cover portion 224, is unfilled. In yet other examples, insulating component 201, when used in conjunction with one of, some of, or all of, lid insulating structure 102, side insulating structures 475, and bottom insulating structure 465, may use an insulating portion 615 that is a solid material (e.g., polymer or polymer blend), such that cavity 214 of insulating component 201 is filled with a solid material of the same or different composition relative to the surrounding by retaining portion 205 and cover portion 224. For example, in some embodiments lid insulating structure 102 may be formed of one material, and in other embodiments lid insulating structure 102 may be formed of two or more materials of varying density, such as in the case in which insulating portion 615 is formed of a polymer having a density that is lower than that of a polymer for forming the surrounding retaining portion 205 and cover portion 224. In general, material forming lid insulating structure 102 and base insulating structure 104 may have a higher density on outside surfaces and a lower density on the internal portions. In some examples, the material forming lid insulating structure 102 and base insulating structure 104 may be polyethylene having a varying density or the same density throughout.
FIGS. 4A-4C schematically depict base insulating structure 404 that may be utilized with the systems and methods described herein for achieving improved thermal resistance of insulating container 100. Base insulating structure 404 and the lid insulating structure 102 cooperate to enclose storage compartment 445 and these structures may be manufactured of similar materials. In one example, base insulating structure 404 may correspond to base insulating structure 104 of insulating container 100 depicted in FIG. 1. Accordingly, in one example, FIG. 4A schematically depicts a top view of base structure 404, FIG. 4B schematically depicts a cross-sectional front elevation view of insulating base structure 404, and FIG. 4C schematically depicts a cross-sectional end elevation view of base structure 404. In one example, the base insulating structures schematically depicted in FIGS. 4A-4C may be formed from one or more molded polymers, and may include storage compartment 445, which may be referred to as an inner trough structure. Inner trough structure 445 may be surrounded by (e.g., bounded at is periphery, for example on four sides) by side insulating structure(s) 475, having outer surface(s) corresponding to side outer faces 108a, 108b, 108c, and 108d of FIG. 1. A single side insulating structure 475 may include a single element, such as an insulating component 201 (see FIG. 2A), with or without insulating portion 615, extending continuously about the periphery of inner trough structure 445. Multiple side insulating structures 475 may include different, or additional elements, such as an enclosed space 480a, as better depicted in FIGS. 4B and 4C. In the case of multiple side insulating structures, these may extend about discreet sections (e.g., sides) of the periphery of inner trough structure 445. For example, two side insulating structures 475, having insulating components 201 with respective cavities 214 that are filled with granulated foam polymer may have outer surfaces corresponding to some or all of opposite side outer faces 108a, 108c, whereas two side insulating structures 475 having enclosed spaces 480a may have outer surfaces corresponding to some or all of opposite side outer faces 108b, 108d. According to the embodiment of FIGS. 4B and 4C, side insulating structure 475 may include outer wall 437a with its outer surface corresponding to all or a portion of one or more of side outer faces 108a, 108b, 108c, and 108d of FIG. 1. Outer wall 437a of side insulating structure 475 may cooperate with opposing inner wall 439a, as well as opposing top and bottom walls 441a, 443a, to form an internal cavity or enclosed space 480a. Although enclosed space 480a is shown as having a rectangular geometry, those skilled in the art with the knowledge of the present disclosure will appreciate that other geometries are possible, including rounded (e.g. oval) geometry, as dictated by the geometries of walls 437a, 439a, 441a, and 443a. Also, whereas four discreet walls are depicted in FIGS. 4B, 4C, enclosed space 480a may likewise be formed from a single continuous (e.g., curved), surrounding wall or any number of discreet walls. In some embodiments, walls 437a, 439a, 441a, and 443a may have wall thicknesses, or possibly minimal wall thicknesses (if not constant) generally in the range of about 0.05 in. to about 0.25 in., with a representative thickness being about 0.15 inches. In some examples, enclosed space 480a may surround inner trough structure 445 on four sides of its periphery, for example in the case of side insulating structure 475 having respective outer surfaces corresponding to side outer faces 108a, 108b, 108c, and 108d of FIG. 1. One or more side insulating structures 475 may include enclosed space(s) that are optionally filled or at least partially filled with insulating material as described above with respect to hollow portions 351 and/or cavities 214. One or more side insulating structure(s) 475, rather than having enclosed space 480a as shown in the embodiments of FIGS. 4B and 4C, may instead be used in conjunction with insulating component(s) 201 and their respective cavity/cavities 214, as described above. In one implementation of side insulating structure 475, enclosed space 480a may be only substantially enclosed and include one or more openings 450, which may be resealable or closeable, through which insulating material, as described above, may be inserted. In other examples, one or more enclosed spaces may be formed in other parts of insulating base structure 404, including for example in the top wall 441b between the enclosed space 480b of bottom insulating structure 465 and the inner trough structure 445.
Similar to the description above with respect to side insulating structure 475, bottom insulating structure 465 may likewise include an element, such as an insulating component 201 (see FIG. 2A), with or without insulating portion 615, or an enclosed space 480b formed from opposing top and bottom walls 441b, 443b, in cooperation with opposing side walls 437b, 439b, as depicted in FIGS. 4B and 4C. According to the embodiment of FIGS. 4B and 4C, an outer surface of bottom wall 443b of bottom insulating structure 465 may correspond to all or a portion of bottom outer face 455 of insulating container 100. As is also apparent from FIGS. 4B and 4C, walls of side insulating structure 475 may connect to, or otherwise share common portions with, walls of bottom insulating structure 465.
In one example, bottom insulating structure 465 rather than having enclosed space 480b as shown in the embodiments of FIGS. 4B and 4C, may instead be used in conjunction with insulating component(s) 201 and their respective cavity/cavities 214 as described above. A cavity 214, surrounded by retaining portion 205 and cover portion 224, may have insulating portion 615 disposed therein. In this case, cover portion 224 in the embodiment of FIG. 2A may correspond to bottom wall 443b in the embodiment of FIG. 4B. Insulating portion 615 may be sized to fill all or a portion of cavity 214 and be secured therein by bottom wall 443b or other cover portion 224. As discussed in more detail below, insulating portion 615 may comprise one or more a vacuum insulated panels 625.
In embodiments in which bottom insulating structure 465 is used in conjunction with insulating component 201, cover portion 224 may be placed over the insulating portion 615 and may secure the insulating portion 615 within cavity 214. Insulating portion 615 may also be secured within cavity 214 using, as an alternative to, or in addition to, cover portion 224, adhesives, tape, or other devices. Cover portion 224 may include at least a portion of bottom wall 443b of base insulating structure 404. In other embodiments, cover portion 224 may engage an inside surface of cavity 214.
Cover portion 224 may be fastened to base insulating structure 404 by any means suitable, including for example, using chemical bonding agents including adhesives, using mechanical fasteners including screws, and/or using thermal bonding (e.g. melting or welding), with or without a separate bonding agent such as low melting point polymer. In some examples, fasteners may be concealed by feet 425. In some examples, cover portion 224 may be engaged with the base insulating structure 404 such that a watertight seal is created. This can advantageously prevent liquids from reaching cavity 214 and/or insulating portion 615 which may reduce the efficiency of insulating portion 615 and insulating container 100 in general.
Cover portion 224 of insulating component 201, in the case of bottom insulating structure 465 being used in conjunction with insulating component 201, may be manufactured of any suitable material. In some examples the cover portion 224 may be manufactured of metals such as stainless steel, plastics, and composites including, for example, carbon fiber. As described above, in some examples cover portion 224 and retaining portion 205 of insulating component 201 may be molded, for example through rotomolding, as a single piece and in other examples cover portion 224 and retaining portion 205 of insulating component 201 may be molded as separate pieces. In some examples, insulating portion 615 may be included within the cavity 214 of insulating component during the molding, for example rotomolding, process. In still other examples, cover portion 224 and other elements may be molded as a single piece without insulating portion 615 included within the cavity 214. In such a process cover portion 224 may be removed, for example, by cutting. Cover portion 224, followed by re-engagement with retaining portion 205.
Similar to the lid insulating structure 102 described above, base insulating structure 404 may be formed from a molded polymer. The molded polymer may offer a comparatively lower thermal conductivity than other structural materials (e.g. metals or alloys). As such, this comparatively lower thermal conductivity may be desirable in order to reduce a rate of heat transfer to or from the inner trough structure 445 from/to an outside environment. Additionally, as described above, the insulating container 100 may comprise one or more voids, or cavities, configured to be filled with one or more additional insulating materials. In one example, internal cavity such as enclosed space 480a, 480b may be, or configured to be, filled with an additional insulating material. This additional insulating material may exhibit higher thermal resistivity properties than the polymer used to mold the structural elements (e.g., walls 437a, 439a, 441a, and 443a) of the insulating container 100. In this way, a material that exhibits higher thermal resistivity, but may be unsuitable for construction of structural elements due to less favorable mechanical properties (e.g. comparatively lower mechanical strength and rigidity than a molded polymer) may be utilized in conjunction with the molded polymer used to construct the structural elements of insulating container 100. The resulting structure of an insulating device, such as container 100, may be a compound, or composite, having a combination of high mechanical strength and rigidity and high thermal resistivity.
In one example, an internal cavity such as enclosed space 480a may comprise multiple sub-cavities separated by one or more by internal structures (e.g. ribs, baffles, flanges, or other structural elements). An internal cavity may comprise multiple discrete cavities. In one implementation, multiple discrete cavities represented by an internal cavity such as enclosed space 480a or cavity 214 of insulation component 201 may be connected to one another by smaller openings. In another example, an internal cavity may be one continuous cavity.
In one specific example, base insulating structure 104 and/or the lid insulating structure 102 may be formed from polyethylene. In another implementation, the systems and methods described herein may be utilized with additional or alternative polymers. For example, the insulating container 100 as a whole, and/or either or both of the base insulating structure 104 and lid insulating structure 102 may utilize polytetrafluoroethylene, polymethylmethacrylate, polypropylene, polyvinyl chloride, polyethylene terephthalate, polystyrene, polycarbonate, polyurethane, and/or blends comprising or consisting of any two or more of these. Further, an internal cavity, as described herein, may be, or may be configured to be, filled with an insulating material. In one example, the insulating material may comprise a polymeric foam, such as a polyurethane foam. However, in another example, additional or alternative insulating materials may be utilized to fill, and adhere to one or more surfaces of an internal cavity, without departing from the scope of the disclosures described herein. The internal cavity may be, or may be configured to be, filled with polystyrene foam, polyvinyl chloride foam, or polyimide foam, among many others. As such, in one example, a polymer or polymer blend used to mold the various structural elements of the insulating container 100, and/or either or both of the base insulating structure 104 and lid insulating structure 102, may have a first thermal resistivity, and an additional insulating material used to fill an internal cavity may have a second thermal resistivity, higher than that of the molded polymer or polymer blend. In yet another implementation, an internal cavity may be filled with a second insulating material that adheres to one or more molded polymeric surfaces of the internal cavity. The second insulating material may also adhere the insulating material to these molded polymeric surfaces or may adhere the insulating material to itself (i.e., act as a binder for the insulating material. For example, a mix of polymer flakes, or pellets, in addition to a second insulating material that is namely a binder may be injected into, or otherwise provided to, an internal cavity.
In one example, an internal cavity such as enclosed space 480a, 480b may be partially filled with an insulating material as described above, such as an insulating foam (polyurethane foam). Partially filling an internal cavity may refer to injecting, or otherwise providing, insulating foam such that an internal cavity may be at least about 50% filled, at least about 80% filled, at least about 85% filled, at least about 90% filled, at least about 95% filled, at least about 97% filled, at least about 99% filled, at least about 99.7% filled, or at least about 99.9% filled, with the percentage filled meaning the total volume, in bulk form, of the insulating material and any second insulation material, divided by the volume of the internal cavity.
In one implementation, specific thermal properties of the insulating container 100 and/or insulating lid structure102 and/or insulating base structure 104 will depend upon specific dimensions and corresponding surface areas, as well as upon the thicknesses of the molded polymeric structures (e.g. thicknesses of walls 437a, 439a, 441a, 443a, 437b, 439b, 441b, 443b of base insulating structure 404), as well as the dimensions, including thicknesses of one or more cavities 214, hollow portions 351, enclosed spaces 480a,b and/or other internal cavities. Such dimensions affect volumes and hence the amount of insulating material that may be contained therein.
In one implementation, the insulating container 100 and/or the insulating lid structure 102 and/or the insulating base structure 104 may be manufactured using one or more rotational molding processes for molding a polymer. As such, those of ordinary skill in the art will recognize various details of a rotational molding processes that may be utilized with the systems and methods described herein without departing from the scope of the disclosures described herein. In another example, the insulating container 100 and/or the insulating lid structure 102 and/or the insulating base structure 104 may be manufactured using one or more additional or alternative molding processes. The insulating container 100 may be molded from one or more polymers using an injection molding process, among others. Furthermore, the insulating container 100 and/or the insulating lid structure 102 and/or the insulating base structure 104 may be further processed using one or more additional manufacturing processes, including, among others, drilling and deburring, cutting, and sanding, without departing from the scope of the disclosures described herein. As depicted in FIGS. 4A-4C, the insulating base structure 404 may be embodied with a substantially cuboidal shape. However, in other implementations, the insulating base structure 404 may be embodied with additional or alternative geometries (e.g. circular, prismoidal, among others), without departing from the scope of these disclosures.
As described above, the insulating portion 615 of an insulating component 201 may comprise one or more vacuum insulated panels 625. Likewise, a hollow portion 351, an enclosed space 480a, b, or other internal cavity as described herein may contain a vacuum insulated panel 625. Vacuum insulated panels as described herein generally comprise a substantially gas-tight enclosure surrounding a rigid core, from which air has been substantially evacuated. The enclosure may comprise membrane walls, which surround a rigid, highly-porous material, such as fumed silica, aerogel, perlite or glass fiber. Vacuum insulated panels may be composed of any other materials commonly known in the industry.
In some embodiments, the one or more vacuum insulated panels may have a thickness of about 0.065 inches or in the range of about 0.03 inches to about 0.1 inches; may have a density (as tested under ASTM D 1622-93) of about 16 lb/ft3 or in the range of about 10 lb/ft3 to about 20 lb/ft3; may have a thermal conductivity (as tested under ASTM C518-93) of about 0.020 BTU-in/ft2-hr-° F. or in the range of about 0.010 BTU-in/ft2-hr-° F. to about 0.030 BTU-in/ft2-hr-° F.; and may have a specific heat of about 0.2 BTU/lb ° F. or in the range of about 0.1 BTU/lb ° F. to about 0.3 BTU/lb ° F.
Vacuum insulated panels 625 used, for example, as insulating portion 615, hollow portion 351, enclosed space 480a, b, or other internal cavity can have any number of different configurations and sizes, including all the configurations and sizes depicted in FIGS. 5A-5H with respect to their use in insulating portion 615. As shown, for example, in FIG. 5A the insulating portion 615 can comprise a single vacuum insulated panel 625.
In embodiments, as shown in FIG. 5B, insulating portion 615 can comprise multiple separate vacuum insulated panels 625 engaged together and forming seams 603 between the separate panels 625. Advantageously, in such a configuration, if one panel 625 fails, the remaining panels 625 may still provide increased thermal resistance.
In still other embodiments as shown in FIGS. 5C-5H the insulating portion 615 can comprise multiple separate vacuum insulated panels 625 having multiple layers of vacuum insulated panels. Similarly, as discussed above, in such a configuration if one panel 625 fails, the remaining panels 625 may still provide increased thermal resistance.
FIGS. 5C and 5D depict six vacuum insulated panels 625 configured in two layers 644, and 646 each have three panels 625 side by side. Although only six panels 625 are shown more panels 625 may be used and insulating portions 615 may be constructed using more than two layers of panels 625. In some embodiments, for example, three or more layers of panels may be used. Similarly as discussed above, in such a configuration if one panel 625 fails, the remaining panels 625 may still provide increased thermal resistance.
FIGS. 5E and 5F depict another alternative configuration of the insulating portion 615 comprising five vacuum insulated panels 625 having a first layer 644 with three vacuum panels 625 side by side and second layer 646 with two vacuum panels side by side. In some embodiments, as shown in FIGS. 5E and 5F the vacuum panels 625 may be arranged such that seams between vacuum panels of first layer 644 do not contact seams between vacuum panels of second layer 646.
[99] In still other embodiments as shown in, for example, FIGS. 5G and 5H, the vacuum insulated panels 625 forming insulating portion 615 can have other configurations. As shown in FIGS. 5G and 5H the vacuum insulated panels of a first layer 644 may be arranged such that seams of a the first layer 644 do not touch parallel seams of a second layer 646.
FIG. 6 schematically depicts an exploded isometric view of a base insulating structure 650 of an insulating container, similar to insulating container 100, according to one or more aspects described herein. In one example, the insulating structure 650 may be similar to the base insulating structure 104, and include one or more elements similar to those described in relation to the base insulating structure 104. In one implementation, and as schematically depicted in FIG. 6, the base insulating structure 650 may be constructed from two primary elements, including an outer shell 652, and an inner wall structure 654. The outer shell 652 may be constructed using one or more sheet metal deep-drawing and/or stamping processes, and using, in one example, a stainless steel material. It is contemplated, however, that the outer shell 652 may be constructed from one or more additional or alternative metals, alloys, polymers or composite materials, and constructed using one or more deep drawing or molding processes. Similarly, the inner wall structure 654 may be constructed using one or more sheet metal deep-drawing and/or stamping processes, and from one or more same or different materials to the outer shell 652. As such, the inner wall structure 654 may be constructed using a stainless steel material. However, it is contemplated that the base insulating structure 650 may be constructed using one or more additional or alternative metals and/or alloys, one or more fiber-reinforced materials, one or more polymers, or one or more ceramics, or combinations thereof, among others, without departing from the scope of these disclosures. In one example, the one or more deep drawing, stamping, and/or molding processes utilized to produce the geometry of the inner wall structure 654 may also form a flange surface 656.
In one example, the inner wall structure 654 of the base insulating structure 650 may be rigidly coupled to the outer shell 652 by one or more coupling processes that are configured to couple the flange surface 656 to one or more of the edges 658, 660, 662, and/or 664. In one specific example, the inner wall structure 654 may be secured to the outer shell 652 by one or more welding or brazing processes, including, among others, shielded metal arc, gas tungsten arc, gas metal arc, flux-cored arc, submerged arc, electroslag, ultrasonic, cold pressure, electromagnetic pulse, laser beam, or friction welding processes. In another example, the outer shell 652 may be rigidly coupled to the inner wall structure 654 by one or more adhesives, by a sheet metal hem joint, or by one or more fastener elements (e.g. one or more screws, rivets, pins, bolts, or staples, among others). In yet another example, the outer shell 652 may be coupled to the inner wall structure 654 by one or more processes configured to couple two polymeric structures together, including ultrasonic welding, among others.
As depicted in FIG. 6, the inner wall structure 654 includes a cavity 670, that, when the base insulating structure 650 is coupled (hingedly, removably, or otherwise) to the lid insulating structure, such as lid insulating structure 102, forms an internal storage compartment. Additionally, when coupled to one another, the outer shell 652 and the inner wall structure 654 form a cavity therebetween, as schematically depicted as cavity 710 in FIGS. 7A-7D.
FIGS. 7A-7D schematically depict a plan view, front elevation view, bottom view, and an end elevation view, respectively, of the base insulating structure 650, according to one or more aspects described herein. As schematically depicted in FIGS. 7A-7D, a cavity 710 is formed between the outer shell 652 and the inner wall structure 654. Further, the base insulating structure 650 may include four feet elements 712, 714, 716, and 718 configured to support the structure 650 on a surface.
Additionally, the base insulating structure 650 may include an insulating portion 615 positioned within the cavity 710. FIG. 8 schematically depicts an exploded isometric view of the base insulating structure 650 having an insulating portion 615 coupled to an internal surface 804 of the inner wall structure 654, according to one or more aspects described herein. It is contemplated that the insulating portion 615 may be coupled to the internal surface 804 by any coupling means, including one or more adhesives, or mechanical fasteners, among others. Alternatively, it is contemplated that the insulating portion 615 may be coupled to an internal surface of the outer shell 652, e.g. internal surface 802, without departing from the scope of these disclosures. Additionally, while a single insulating portion 615 is depicted in FIG. 8, it is contemplated that multiple insulating portions 615 may be integrated into the insulating structure 650, and may partially or wholly cover the internal surface 804, in addition to one or more additional internal surfaces of the inner wall structure 654, without departing from the scope of these disclosures.
In one example, the one or more insulating portion 615 may partially or wholly fill the cavity 710 between the outer shell 652 and the inner wall structure 654. In one implementation, the cavity 710 may be partially filled with an insulating foam, such as one or more of the insulating foams previously described. Accordingly, the base insulating structure 650 may be constructed by positioning and insulating portion 615 in the cavity 710 prior to the outer shell 652 being rigidly coupled to the inner wall structure 654. For example, the insulating portion 615 may be loosely positioned within the cavity 710, or introduced into the cavity 710 by being adhered to the internal surface 804. Subsequently, following one or more processes configured to couple the outer shell 652 to the inner wall structure 654, an insulating foam may be introduced into the cavity 710 to partially or wholly fill an unfilled volume of the cavity 710. In one example, the insulating foam may be introduced into the cavity 710 through one or more openings in the bottom surface of the base insulating structure 650, with said one or more openings sealed by one or more of the depicted feet elements 712-718.
FIG. 9 schematically depicts a cross-sectional front elevation view of another implementation of a base insulating structure 900, according to one or more aspects described herein. In one example, the base insulating structure 900 may be similar to the base insulating structure 104, and constructed using one or more materials and/or processes described in relation to base insulating structure 104. In one implementation, the base insulating structure 900 includes side insulating structures 975 and a bottom insulating structure 965 that form an inner trough structure/internal storage compartment 950, and that is used as an internal storage compartment when the base insulating structure 900 is coupled to a lid structure, such as lid insulating structure 102. Accordingly, the bottom insulating structure 965 and side insulating structures 975 may comprise an insulated wall structure 902 that may be constructed from one or more insulating materials similar to those described throughout these disclosures. In one specific example, the insulating wall structure 902 may comprise one or more polymers, such as polyethylene or polycarbonate, or any other polymer, described in these disclosures. Additionally or alternatively, the insulated wall structure 902 may comprise one or more metals, alloys, or composite materials.
As depicted in FIG. 9, the insulated wall structure 902 may connect to, or otherwise share common portions with, the bottom insulating structure 965 and the side insulating structures 975. In one example, the bottom insulating structure 965 and the side insulating structures 975 may be similar to the insulating component 201, and such that a portion of the insulated wall structure 902 is similar to the retaining portion 205. Additionally, the bottom insulating structure 965 and the side insulating structures 975 may include cavities 904, 906, and 908 that may be similar to cavity 214 described in relation to the retaining portion 205. Further, the base insulating structure 900 may include cover portions 910, 912, and 914, which may be similar to cover portion 224, as previously described. As such, the bottom insulating structure 965 and the side insulating structures 975 may be configured to receive insulating portions 615 into the respective cavities 904, 906, and 908.
In one implementation, the cover portions 910, 912, and 914 may be rigidly coupled to the bottom insulating structure 965 and the side insulating structures 975 to retain the insulating portions 615 within the cavities 904, 906, 908.

In one example, the base insulating structure 1100 may be similar to the base insulating structure 104, and constructed using one or more similar materials and processes. In one specific implementation, the first stage depicted in FIG. 11A may mold a polymer foam around insulating portions 615 to form core structures 1104, 1106, and 1108. In one example, the core structures may be referred to as side core structures 1104 and 1008, and bottom core structure 1106. It is contemplated that the core structures 1104, 1106, and 1108 may be formed as a single structure, or as multiple separate structures coupled to one another by connection elements. It is contemplated that any connection elements may be utilized, including, among others, one or more wire elements, or sacrificial polymer elements configured to position the core structures 1104, 1106, and 1108 relative to one another prior to one or more rotational molding processes. Further, it is contemplated that a similar process to that described in relation to FIGS. 11A-11B may be utilized to construct a lid insulating portion, similar to lid insulating portion 102 described in relation to FIG. 1.
In one implementation, the core structures 1104, 1106, and 1108 may be constructed from polymeric foam, such as polyurethane.

The foldable insulating portion 1200 may comprise multiple insulating components 1210a-1210e coupled to one another by flexure elements 1214a-1214d. Accordingly, the flexure elements 1214a-1214d facilitate rotation of the insulating components 1210a-1210e relative to one another along hinge lines schematically depicted as lines 1216a-1216d. In one implementation, the combination of the insulating components 1210a-1210e and flexure elements 1214a-1214d may be referred to as a foldable support structure. Further, each of the insulating components 1210a-1210e may include a retaining portion 1202 that may be similar to the retaining portion 205, and a cavity 1204, which may be similar to cavity 214. Element 1220 may include a single vacuum insulated panel, or multiple vacuum insulated panels arranged in a manner similar to that described in relation to the insulating portion 615. In various implementations, the foldable insulating portion 1200 may be utilized as an alternative to the insulating portion 615, where described throughout these disclosures. For example, the foldable insulating portion 1200 may be utilized within the base insulating structures 650, 900, 1000, and/or 1100, without departing from the scope of these disclosures.
In one implementation, the foldable insulating portion 1200 may be utilized in the various implementations described throughout this disclosure in addition to, or as an alternative to, the described insulating portion 615.

Accordingly, the depicted implementation of the foldable insulating portion 1200 is configured to be folded into a five-sided assembly that may form part of a base insulating structure, similar to base insulating structure 104. Advantageously, the foldable insulating portion 1200 may allow for more precise placement of the vacuum insulated panels 1220 within, in one example, a base insulating structure. This, in turn, may provide enhanced insulating performance to the base insulating structure by providing enhanced insulation at, among others, one or more edges of a structure as the folded assembly extends around one or more corners of a structure into which it is received and coupled. Additionally, the foldable insulating portion 1200 may provide for increased precision during one or more assembly operations of, in one example, base insulating structure 104.
It is contemplated that alternative implementations of a foldable insulating portion may be utilized, without departing from the scope of these disclosures. In one example, and as depicted in FIG. 13 as foldable insulating portion 1300, a four-sided foldable insulating portion may be utilized. Accordingly, the foldable insulating portion 1300 may be configured to be folded into an assembly having four sides that extend around at least one corner of a base insulating structure, such as base insulating structure 104. It is further contemplated that alternative implementations of a foldable insulating portion utilizing multiple insulating components 1210 and flexure elements 1214 may be envisioned, without departing from the scope of these disclosures. For example, a foldable insulating portion may utilize two insulating components 1210, three insulating components 1210, or six insulating components 1210, and interconnected by flexure elements 1214 in any configuration, without departing from the scope of these disclosures.

It is contemplated, however, that additional insulating components and flexure elements may be utilized, without departing from the scope of these disclosures. The insulating components 1210a-1210b may be folded from an unassembled configuration, depicted in FIG. 14A, to an assembled configuration, depicted in FIG. 14B. The assembled configuration of FIG. 14B may result in the insulating components 1210a-1210b being positioned at an angle 1402 relative to one another. This angle 1402 may measure approximately 90°. However, it is contemplated that angle 1402 may have any value, without departing from the scope of these disclosures.
In the depicted implementation in FIGS. 14A-14B, the insulating components 1210a-1210b, when folded into the assembly of FIG. 14B results in a non-overlapping configuration of the insulating components 1210a-1210b. In an alternative implementation, the insulating components 1210a-1210b may overlap when folded into an assembled configuration, as described in relation to FIGS. 15A-15B. Accordingly, FIGS. 15A-15B schematically depict end views another implementation of a foldable insulating portion 1500, according to one or more aspects described herein. When folded from the unassembled configuration of FIG. 15A to the assembled configuration of FIG. 15B, the insulating components 1210a-1210b may overlap one another, which may result in enhanced insulation performance (i.e. higher insulation value). However, it is contemplated that additional or alternative folding methodologies, such as partial overlapping of insulating components 1210, among others, may be utilized, without departing from the scope of these disclosures.

The collar structures 2109, 2111 are configured to be to be positioned between the outer wall structures 2106, 2114 and are configured to engage each other around a perimeter of the insulating container 2100. Additionally, an end cap structure 2116 is configured to be rigidly coupled to a bottom of the base outer shell structure 2114 and/or the base inner wall structure 2110. As shown in FIG. 24, the cavity 2105 also extends between the end cap structure 2116 and the inner wall structure 2110 and the outer shell structure 2114. The insulating container 2100 may also comprise one or more latches 2115, handles 2117, and/or hinges 2119 which may be similar to latches, handles, and hinges described herein.
In some examples, and as shown in FIG. 24, the lid outer shell 2106 and the base outer shell 2114 may be formed of sheet metal such as stainless steel material.

The base outer shell 2114 may engage or be coupled to the end cap 2116 similarly. As shown in FIGS. 24, 25A, and 30A, the base outer shell 2114 may include a bottom, substantially downward, flange 2141. The flange 2141 may extend substantially, or all of the way around the perimeter of the base outer shell 2114. The end cap 2116 may include a corresponding channel 2143 which the flange 2131 engages within. Advantageously, such an engagement between the outer shell 2114 and the end cap 2116 may serve to enhance the overall strength of the insulating structure 2100.

For example, insulating structure 2100 may in one embodiment include a lid insulating portion or lid insulating panel 2151 in the cavity 2103. The lid insulating portion 2151 may be engaged with the inner wall structure 2108. Similarly, the insulating structure 2100 may in one embodiment include a base insulating structure comprised of two separate side insulating panels 2153 and a 3-sided foldable or bendable insulating panel 2155. Panels 2153 and 2155 may be engaged with the base inner wall structure 2110. Similarly, to foldable insulating portions 1200,1300, and 1400, the 3-sided insulating panel 2155 may comprise multiple insulating components coupled to one another by flexure elements. Additionally, also like panels 1200, 1300, and 1400, the 3-sided insulating panel 2155 may be a single vacuum insulated panel, or multiple vacuum insulated panels arranged in a manner similar to that described in relation to the insulating portion 615. In one example, as best shown in FIGS. 28A and 28B, the 3-sided insulating panel 2155 may comprise a single vacuum insulated panel and including folded areas 2157. The folded areas 2157 of the 3-sided vacuum insulate insulated panel 2155 may be compressed more than the non-folded portions 2159 of the panel 2155 such that the thickness of the folded area 2157 is less than the thickness of the non-folded portions 2159. Additionally, in some embodiments, the panels 2151, 2153, and/or 2155 may include one or more cut-out or notched portions. As shown in FIGS. 27B and 27C the lid insulating panel 2153 may have a cut-out or notched portion 2153a which may be used to accommodate a bottle opener. Similarly, as shown in FIGS. 25B and 28A, the insulating panel 2155 may include a cut-out or notched portion 2155a which may be used to accommodate a drain 2161. In other embodiments, panels 2153 and 2155 may not include cut-out or notched portions and may instead be made smaller to accommodate additional hardware including the bottle opener and the drain 2161. As discussed above, insulating panels 2151, 2153, 2155 may be constructed similar to any of the vacuum insulated panels discussed herein.
As shown in FIGS. 29A and 29B, the drain 2161 may pass through the end cap 2116, and the base inner wall structure 2110. The drain 2161 may include a drain pass-through portion 2163 having a threaded connection 2165 on either end and a rim 2167 on at least one end. The drain 2161 may also include a gasket 2169, a nut 2171 having an aperture, and cap 2173. As shown in FIG. 29A, the rim 2167 may engage the end cap 2116 and the gasket may engage the inner wall structure 2110. The nut 2171 may then tighten the drain portions together.
As discussed above, in one example, after installing vacuum insulated panels (including panels 2151, 2153, and 2155) into cavities 2103 and 2105 the cavities 2103 and 2105 may be partially or wholly filled with an insulating foam, such as one or more of the insulating foams previously described. Accordingly, the lid insulating structure 2102 may be constructed by positioning vacuum insulated panel 2151 in cavity 2103. In some embodiments, panel 2151 may be coupled with lid inner wall structure 2108. Lid inner wall structure 2108 may then be coupled with lid outer shell 2106 including by engaging some or all of the mechanical fasteners 2127. Insulating foam may then be injected into the remaining portions of cavity 2103. The insulating foam may partially or wholly fill an unfilled volume of the cavity 2103. Similarly, the base insulating structure 2104 may be constructed by positioning vacuum insulated panels 2153, 2155 in cavity 2105. In some embodiments, panels 2153, 2155 may be coupled with base inner wall structure 2110. Base outer shell 2114 may then be coupled with base inner wall structure 2110 and end cap 2116 including by engaging some or all of the mechanical fasteners 2127. Insulating foam may then be injected into the remaining portions of cavity 2105. The insulating foam may partially or wholly fill an unfilled volume of the cavity 2105.
It is contemplated that the vacuum insulated panels 625 may comprise any vacuum insulated panel type, including any commercially available vacuum insulated panel.

In certain examples, specific models of vacuum insulated panels 625 were tested to determine their relative efficacy. FIG. 16 depicts a table of results of heat transfer tests conducted on insulating containers configured with five different types of vacuum insulated panels. The tested insulating containers are similar to insulating container 100, and the five different types of vacuum insulated panels include: i) 10 mm Panasonic Aluminum (type A), ii) 10 mm Panasonic vaporized metal (type C), iii) 6 mm Va-Q-Tec, iv) 12 mm Va-Q-Tec, and v) 18 mm Va-Q-Tec. The testing methodology included adjusting a temperature within an internal storage compartment of an insulating container to a temperature below 10° F. by introducing 19.5 lbs of ice cooled to −22° F. into the internal storage compartment. The test results presented in table 1600 of FIG. 16 measure the time taken for the internal temperature to rise from 10° F. to 50° F. when the insulating container is closed, and placed within an external environment having an ambient temperature of 100° F.
Benefits
Embodiments of this disclosure present many benefits over existing insulating containers.
Vacuum insulated panels may provide a similar thermal resistance to an insulating foam while having a reduced thickness as compared to the insulating foam. Thus, for example, as described above, strategic placement of vacuum insulated panels within an insulating container may improve the thermal resistance of the insulating container and/or allow more space to store items within the storage compartment.
For example, an insulating container containing vacuum insulated panels as described above, may provide increased thermal resistance as compared to a similarly sized insulating container molded from a polymer and filled with an insulating foam that does not have vacuum insulated panels. Additionally, for example, an insulating container containing vacuum insulated panels as described above, may provide increased storage room within the storage compartment as compared to an insulating container having similar thermal resistance molded from a polymer and filled with an insulating foam that does not have vacuum insulated panels.
The present disclosure is disclosed above and in the accompanying drawings with reference to a variety of examples. The purpose served by the disclosure, however, is to provide examples of the various features and concepts related to the disclosure, not to limit the scope of the invention. One skilled in the relevant art will recognize that numerous variations and modifications may be made to the examples described above without departing from the scope of the present disclosure.
