[0003] Cartons for cooking food in a microwave oven are known. Such cartons may include a microwave susceptor, which has the property of increasing its own temperature by partially absorbing energy of the microwave and then transmitting thermal energy to the food. This helps to provide browned or crispened areas where the food product is in contact with the susceptor material. Microwave ovens are typically equipped with a turntable to provide more even cooking.

[0004] It is against this background that the disclosure is made.SUMMARY

[0053] In the realm of microwavable food packaging, particularly for larger items such as food items having a major dimension of at least four inches or more, existing arrangements encounter limitations in cooking. One notable problem is that quadrilateral containers, cartons, and trays large enough to accommodate the food item cannot rotate on a turntable of a microwave oven or other cooking or food preparation device due to spatial constraints within the device. This lack of rotation leads to uneven cooking, as the microwave energy is not uniformly distributed throughout the food item. Consequently, certain areas of the food item may be overcooked or undercooked, compromising the overall quality and enjoyment of the food item.

[0054] One solution to this problem has been to use round or pressed containers, however the use of round and pressed containers introduces another set of challenges. Round or pressed containers, while potentially capable of rotating freely within a confined space, are markedly more expensive to manufacture. Increased production costs stem from complexities involved in manufacturing pressed and formed package shapes, as well as increased waste in cutaway portions of the original stock material. Additionally, round and pressed containers are typically shipped fully formed which reduces shipping density and thus is more expensive.

[0055] Embodiments of the present disclosure address these challenges through the incorporation of chamfered corners configured to reduce a diagonal dimension of an otherwise quadrilateral or polygonal microwavable container. Although specific examples of an eight-sided container are depicted, the concepts as disclosed herein are suitable to other polynomial shapes. As used herein, “quadrilateral” refers to any polygonal shape and is not limited to four-sided containers.

[0056] As used herein, a “container” can refer to any receptacle or enclosure designed to hold, store, transport, or protect items, including food products. Containers can vary widely in size, shape, material, and functionality, catering to the specific needs of the contents they hold. The materials used for containers are often chosen for properties that best suit the item's requirements, such as durability, protection, and environmental conditions. Features of containers may include airtight seals, handles for easy transportation, and mechanisms for controlled dispensing.

[0057] A “carton” can refer to a type of packaging container designed to hold, protect, and preserve food items during storage, transportation, display, preparation, and consumption. Cartons can vary in size, shape, and functionality depending on the specific food product they are intended for. A carton may include features such as folding closures, perforations for easy opening, cooking surfaces, and coatings or laminates to provide barrier properties against moisture, oxygen, and other environmental factors that could affect the food's quality and freshness.

[0058] A “tray” can refer to a shallow platform designed for the carrying, holding, cooking, or presenting of various items, including food products. Trays can vary in size, shape, material, and design, tailored to the specific application or aesthetic preference. The materials used for trays are often selected for properties that complement the tray's intended use, such as lightweight durability, ease of cleaning, or decorative appeal. Features of trays may include raised edges to prevent items from sliding off, compartments for organizing contents, and handles or grips for easy carrying. In some embodiments, a tray and food product may be contained within a carton.

[0059] Additionally, a container can function as both a carton and a tray. Typically, a carton is defined as a six-sided (or more) enclosure providing comprehensive protection and containment, while a tray is described as an open, five-sided (or more) platform designed for ease of access and presentation. In some embodiments, removing or hinging a top lid or cover from a carton (e.g., a major surface of the carton) can convert it into a tray, offering a versatile solution that facilitates secure product containment as well as convenient display or access when desired.

[0060] “Packaging” refers to any material or structure designed for the enclosing or protection of items, particularly food products, during their storage, transportation, display, preparation, and consumption. This broad definition encompasses containers, cartons, and trays, each serving specific roles within the realm of packaging but united in their purpose to safeguard and maintain the quality of the contents they hold. Packaging materials and designs can be chosen based on the needs of the product, considering factors like durability, environmental conditions, and the preservation of freshness and quality.

[0061] While the present disclosure provides examples of the use of the concept within the confines of a cooking apparatus, it should be understood that the concept is not limited to “cooking”. The disclosed invention is also applicable to the preservation and serving of uncooked foods, such as pies or other desserts. The described containers, cartons, and trays can be effectively utilized to store, protect, and present these food items, ensuring their quality and freshness without the need for a cooking step. For example, a pie may be preserved in a container with chamfered corners for efficient storage and transport, and subsequently served directly from the tray.

[0062] Reference will now be made in detail to exemplary aspects of the present disclosure that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0063] Referring now to FIGS. 1-4, a food container 100 is depicted in accordance with an embodiment of the present disclosure. The food container 100 may comprise a base panel 102, a cover panel 104, and a chamfered sidewall 106 which can be constructed of a plurality of panels forming a polygonal shape. As shown in FIG. 1, the base panel 102, the cover panel 104, and the chamfered sidewall 106 are configured to cooperatively define a sealed interior 108 for the containment of a food item 50. As illustrated in FIG. 2, a lid portion 110, defined by the cover panel 104, and the chamfered sidewall 106, is capable of being opened to facilitate access to the interior 108. Subsequently, as depicted in FIGS. 3 and 4, the food item 50 may be extracted from the interior 108 through the open top of the food container 100, and the lid portion 110 may be rotated up to approximately 360° relative to the remaining structure of the food container 100, from an initial state in the food storage configuration wherein the food preparation surface of the lid portion faces toward the interior 108, to a substantially inverted state in the food preparation configuration wherein the food preparation surface of the lid portion faces away from the interior 108, exposing a food preparation surface 112 located on a surface of the lid portion 110. Following this, the food item 50 may be placed upon the food preparation surface 112, while the remaining structure of the food container 100 positioned below the food preparation surface 112 functions as a thermal insulator, inhibiting the underlying surface from acting as a heat sink during the food preparation process while also allowing more microwave energy to interact with the susceptor and bottom of the food product.

[0064] With additional reference to FIG. 5, a flat 160 representation of the food container 100 is shown prior to its assembly into a three-dimensional configuration. In embodiments, the flat 160 may be fabricated from a paperboard material, although the utilization of alternative materials such as plastics and composites is also contemplated. Each panel delineated by the flat 160 may be separated from an adjacent panel by a fold line or bend defined by the flat 160.

[0065] A “fold line” or “bend” facilitates the folding or bending of one panel relative to an adjacent panel. The term “fold line” refers to a predefined line on the material which enables controlled folding without material breakage. A “bend” denotes pre-formed curves or angles in the material that aid in shaping, assembling, or enhancing the structural integrity of the packaging. These intentional deformations in the packaging material are important for creating corners, edges, or folds that contribute to the container's, carton's, or tray's ability to maintain its form, assist in its assembly, and transition from a flat sheet to a complex, three-dimensional structure. This structure is capable of containing, protecting, and facilitating the preparation of food products, and allows for the efficient transformation of flat materials into functional packaging solutions.

[0066] In some embodiments, the flat 160 may be precut to specified dimensions and distributed in a flat configuration, enabling subsequent assembly into the food container or another three-dimensional form as required.

[0067] As depicted, the base panel 102 can be defined by a base panel edge 114. Similarly, the cover panel 104 is defined by a cover panel edge 116. In certain embodiments, both the base panel 102 and the cover panel 104 may be integral internal panels, each bordered entirely by segments of the flat 160 constituting the chamfered sidewall 106. For example, in some embodiments, each of the base panel edge 114 and the cover panel edge 116 may be represented as a bend or fold line.

[0068] In various embodiments, the base panel 102 and the cover panel 104 may exhibit similar geometrical shapes, representing the bottom and top, respectively, of the assembled food container 100. As depicted, the base panel 102 and the cover panel 104 can be positioned parallel to and aligned with one another along a longer edge or dimension of the generally rectangular peripheral edge of the flat 160. In this configuration, at least one integrally formed internal panel (e.g., second panel 120) is positioned between the base panel 102 and the cover panel 104, defining two-fold lines or bends. In certain embodiments, the base panel edge 114 and the cover panel edge 116 may each be configured as an eight-sided figure, such as a regular octagon (e.g., comprising eight internal angles each measuring approximately 135°) or an irregular octagon (e.g., comprising internal angles alternating between approximately 112.5° and 157.5°, or any other two corresponding angles that total approximately 270°). It is contemplated that other polygonal configurations for the base panel 102 and the cover panel 104 may be employed, each varying in shape and size.

[0069] As further depicted in FIG. 5, the chamfered sidewall 106 can be composed of multiple panels that operatively connect the base panel 102 to the cover panel 104, thereby forming the interior 108 in the folded configuration. Specifically, the chamfered sidewall 106 can include a first panel 118, a second panel 120, and sets of third and fourth panels 122A-B and 124A-B, respectively. These panels collectively constitute four substantially orthogonally oriented sides of the chamfered sidewall 106.

[0070] In the folded configuration, the first panel 118 can be joined to panel 132 to exhibit a double layer thickness. The second panel 120 can exhibit a single layer thickness, comprising a singular material layer, while the third and fourth panels 122A-B and 124A-B can exhibit a double layer thickness, with either 122A or 122B and 124A or 122B positioned on an interior of the chamfered sidewall 106. Other thicknesses and layering configurations are also contemplated. For example, although the third and fourth panels 122A-B and 124A-B are depicted as having equal widths, certain panels can alternatively be designed as partial-width segments, exhibiting a partially overlapping width with their counterpart panels. Additionally, panel 132 may be configured to either partially or fully overlap with the first panel 118, allowing for greater flexibility in width and overlap configurations depending on the specific design requirements.

[0071] Each of the first, second, third, and fourth panels 118, 120, 122A-B, 124A-B can be interconnected along their respective edges by four chamfered corners 126A-D. The assembly of the various panels results in the formation of an eight-sided chamfered sidewall 106 positioned between the base panel 102 and the cover panel 104 to delineate the interior 108.

[0072] Additionally, as depicted in FIG. 5, the flat 160 can define a plurality of triangular-shaped areas 128A-D, 130A-D, designed to fold in relation to the base panel 102 or cover panel 104, to facilitate the positioning of the chamfered corners 126A-D in an octagonal formation. In certain embodiments, the triangular-shaped areas 128A-D, 130A-D can be structured to overlap with portions of the base panel 102 or the cover panel 104, allowing for a configuration where the base panel 102 and cover panel 104 may overlap or otherwise extend beyond the boundaries of the chamfered sidewall 106.

[0073] Further, in certain embodiments, the flat 160 may comprise a securement portion 132, which in some cases extends along one side of the flat 160. As illustrated, the securement portion 132 can be located along a first side 134 adjacent to the base panel 102 and triangular-shaped areas 128A, 128B. The securement portion 132 is designed to be affixed to a second, opposing side of the flat 160, for instance, the first panel 118 and chamfered corners 126A, 126B. As depicted in FIG. 6, upon affixing the first side 134 to the second side 136, for example through the securement portion 132, the flat 160 transitions into a three-dimensional rectangular (e.g., tubular) container with open ends (occasionally referred to as glued shells, blanks, or cartons, etc.), adjacent to the third panels 122, and fourth panels 124. In some embodiments, a food item 50 may be positioned within the interior 108 while in this configuration and prior to the interior 108 being sealed.

[0074] Subsequently, the chamfered corners 126A-D can be manipulated inwardly, such that the respective triangular-shaped areas 128A-D, 130A-D overlap with portions of the base panel 102 or cover panel 104, which enables the chamfered corners 126A-D to be positioned between adjacent wall panels, thus forming an eight-sided chamfered sidewall 106, as depicted in FIG. 7. The chamfered corners 126A-D, or another portion of the chamfered sidewall 106, may incorporate securement tabs 138A-D, configured to attach to an adjacent panel within the chamfered sidewall 106, facilitating the creation of a continuous chamfered sidewall 106. As depicted, in some embodiments, the securement tabs 138A-D can extend laterally beyond the outer edge of the third and fourth panels 122A-B, 124A-B, thereby providing an ample securement surface for affixation to the third and fourth panels 122A-B, 124A-B when assembled, while maintaining a desired shape of the base panel 102 and cover panel 104.

[0075] With continued reference to FIG. 5, various panels of the flat 160 can define a lid portion 110. In some embodiments, the lid portion 110 can be defined along its perimeter by a lid portion edge 140, which may comprise a score line or a line of perforations, enabling the separation of the lid portion 110 from other components of the food container 100.

[0076] A “score line,” within the context of a food container, carton, or tray, represents a thin, straight path that constitutes a predefined cut or a line of reduced thickness or structural integrity. Score lines are designed to facilitate precise folding, bending, or separation of the material along the defined path. Various techniques such as exerting pressure or employing cutting tools can be utilized to implement score lines, depending on the material type and the desired functionality. The primary function of a score line is to introduce a line of weakness in an otherwise robust material, thereby aiding in the manipulation of the container, carton, or tray for activities such as folding, bending, opening, assembling, or collapsing the structure.

[0077] “Perforations” are defined as small holes or a series of holes punched or pressed into the material to facilitate specific actions or outcomes. These perforations create zones of reduced material integrity, thereby simplifying the process of tearing or separating the material along the line of perforations. In some configurations, these perforations may align with score lines or bends, enhancing the ease of removing certain portions of the container, carton, or tray. Alternatively, perforations may be positioned independently of score lines to fulfill distinct functions. For instance, perforations might be employed to allow the passage of moisture or air through the layers of a food container, carton, or tray, ensuring even cooking conditions, particularly in microwaveable packages.

[0078] In one embodiment, the lid portion edge 140 is defined by the cover panel 104, the first panel 118, and the second panel 120. In some embodiments, the lid portion edge 140 follows the contour of the cover panel edge 116, allowing the lid portion 110 to adopt a shape similar to that of the cover panel 104. Furthermore, the lid portion 110 may be sized slightly smaller than the cover panel 104, such that upon separation of the lid portion 110 from the cover panel 104 along the lid portion edge 140, a peripheral lip 142 of the cover panel 104 remains intact and in contact with the chamfered sidewall 106, thereby enhancing the structural integrity of the assembly. For instance, as depicted, the peripheral lip 142 may extend along at least six linear sides of the cover panel 104, for example, parallel to the panels of the chamfered sidewall 106, augmenting the stability of the food container 100 even after the detachment of the lid portion 110.

[0079] In some embodiments, the lid portion 110 incorporates chamfered corners that mirror the geometric configuration of the cover panel 104, such that the removal of the lid portion 110 reveals a segment of the triangular-shaped areas 130A-D. Alternatively, in other embodiments, the lid portion 110 features chamfered corners that align with the form of the chamfered sidewall 106, resulting in the lid portion 110 closely matching the dimensions of the interior.

[0080] With additional reference to FIGS. 8-9, to facilitate the separation of the lid portion 110 from the cover panel 104, some embodiments include an extension of the lid portion edge 140 (shown in FIG. 5) to at least the first panel 118, to define a lift tab 144 connected to a remainder of the lid portion by a fold line or bend 145. The lift tab 144, which is depicted as being defined by the first panel 118 (though it could also be defined by other panels such as the third or fourth panels 122A, 122B, 124A, 124B, the chamfered corners 126A-D, or on the cover panel 104), is connected to the rest of the lid portion 110 by fold line or bend 145, and functions as a grip or handle. The lid portion edge 140 outlines the lid portion 110, including the lift tab 144, enabling a clean separation along the lid portion edge 140 when the lid portion 110 is detached from the cover panel 104. Specifically, a user may apply pressure to the lift tab 144, prompting its disengagement from the first panel 118 along the lid portion edge 140. The user can then grasp the lift tab 144 and exert an upward pulling force, away from the cover panel 104, facilitating further separation along the lid portion edge 140 as the lid portion 110 is progressively separated from the cover panel 104.

[0081] Other embodiments of the lift tab 144 can include one or more features to aid in initiating separation of the lid portion 110 from a remainder of the first panel 118 and cover panel 104. In one embodiment, the one or more features, for example in the form of a zipper, tear strip, cut, notch, etc. can be positioned on the first panel 118, the activation or release of which can expose the lift tab 144 for further manipulation.

[0082] With additional reference to FIGS. 10-12, to facilitate the pivoting of the lid portion 110 relative to other portions of the food container 100, the lid portion edge 140 extends to at least the second panel 120, defining a hinge mechanism 146. The hinge mechanism 146 can serve as a pivot point, enabling the lid portion 110 to pivot relative to the rest of the food container 100. In one embodiment, the score line or perforations of the lid portion edge 140 extend through at least half of the width of the second panel 120, up to a first hinge line 148. The cooperative function of the first hinge line 148 (e.g., configured to rotate up to about 180°) and a second hinge line 150 (e.g., also configured to rotate up to about 180°) allows the lid portion 110 to pivot about 360°, bringing the exterior of the lid portion 110 into contact with an exterior portion of the base panel 102.

[0083] In certain embodiments, the lift tab 144, lid portion 110, and hinge mechanism 146 can be positioned in alignment parallel to the longer axis or dimension of the generally rectangular peripheral edge of the flat 160. Arranging the lift tab 144 and hinge mechanism 146 in this configuration enhances the structural integrity of the food container 100, as the second panel 120, which defines the hinge mechanism 146, is an integral internal panel bordered by other portions of the flat 160. Positioning the lift tab 144 on this integral internal panel provides stable support for the lid portion 110, ensuring durability and consistent functionality throughout use.

[0084] As depicted in FIGS. 11-12, the interior of the lid portion 110 can define a food preparation surface 112, which can comprise a susceptor material 154 in some embodiments. Susceptor materials are designed to enhance the browning of food products within the food container 100 when subjected to microwave energy. Such materials are well documented, with examples provided in U.S. Pat. Nos. 4,833,007; 4,230,924; 4,267,420; and 5,107,089, all of which are incorporated by reference herein. In alternative embodiments, the food container 100 may be devoid of a susceptor material. In alternative embodiments, the food container 100 may include absorbent, energy conducting, energy shielding, self-venting, and / or heat dissipating material.

[0085] Furthermore, the food preparation surface 112 may include one or more vents, apertures, or sipes 156, facilitating the passage of moisture during food preparation. “Sipes” are defined as thin, shallow cuts or grooves on the surface of the material, differing from full perforations as they do not create open holes but are finely incised lines that enhance packaging functionality, particularly during cooking or reheating processes. In microwaveable food packaging, sipes can be strategically placed to manage steam and moisture flow, aiding in even heat distribution across the food item by promoting a uniform release of steam from within the container. Additionally, sipes can contribute to moisture and grease management, keeping the base of the food product crisp by effectively channeling excess liquids and vapors away from the cooking surface.

[0086] In some embodiments, one or more sipes 156 may be configured in an array or arrangement to facilitate moisture escape during cooking, as well as to allow for the drainage of moisture and / or grease from the food item. While the sipes 156 are illustrated on the food preparation surface 112, in other embodiments, components such as portions of the chamfered sidewall 106 or the base panel 102 may incorporate a vent or other form of aperture, gap, or discontinuation to facilitate venting.

[0087] In some embodiments, the perforations, holes, or sipes may extend through both the susceptor material 154 and the lid portion 110, particularly in configurations where these elements are bonded or otherwise joined. Alternatively, the perforations, holes, or sipes may be designed to solely penetrate either the susceptor material 154 or the lid portion 110. In another embodiment, the food preparation surface 112 may exclude any perforations, holes, or sipes.

[0088] In operation, the described food container 100 can be converted from a storage configuration, (such as that depicted in FIG. 7) to a food preparation configuration (such as that depicted in FIG. 12). The conversion process can begin by initiating the separation of the lid portion 110 from the cover panel 104. This can be facilitated along a lid portion edge 140, which may include one or more of the following features: perforations, a precut line, or a line of material weakness. The lid portion edge 140 can extend to at least one of the wall panels, thereby partially defining a hinge mechanism 146, to ensure that while the lid portion 110 is detached from the main body of the cover panel 104, the lid portion 110 remains partially attached at the hinge mechanism 146 to enable subsequent pivotal action.

[0089] In embodiments, the lid portion edge 140 can be configured to provide sufficient resistance to maintain the connection between cover panel 104 and lid portion 110 until an intentional force is applied by the user. This ensures that the lid portion 110 does not separate unintentionally during transport or use prior to conversion.

[0090] Following the detachment, the lid portion 110 can be pivoted about the hinge mechanism 146 to an inverted position. In this configuration, the food preparation surface 112, which is typically located on the interior face of the lid portion 110, is oriented outwardly and away from both the base panel 102 and the chamfered sidewall 106. The pivotal movement is facilitated by the hinge mechanism 146, which acts as a fulcrum allowing the lid portion 110 to rotate smoothly from the closed position to the fully open, food preparation position. In other embodiments the lid portion 110 can be separated (e.g., fully removable, etc.) from the food container 100, as depicted in FIG. 11A.

[0091] The final pivotal movement transitions the food container 100 from its secure storage configuration to a functional food preparation configuration. This repositioning exposes the food preparation surface 112, making it readily accessible for food preparation tasks. This transition not only utilizes the structural elements of the container for functional benefit but also enhances the usability of the container, allowing for efficient space use and ease of food preparation. Thereafter, the food preparation surface 112 may be utilized in the preparation of the food item 50, while the remainder of the food container 100 serves as a stand to elevate the food preparation surface 112. The stand has greater load bearing strength than some orthogonal designs as a result of the increased number of corners and / or overhanging bevel.

[0092] With additional reference to FIG. 13, for improved clarity in understanding relative angles and dimensions of the food container 100′, a top plan view depicting relative dimensions of the food container 100′ is depicted in accordance with an embodiment of the disclosure. As depicted, D4 can represent a length or width of the food container 100′. For example, one embodiment contemplates the use of the food container 100′ to serve as a container for a 10-inch round pizza having a reduced diagonal dimension enabling the food container 100′ to serve as a platform for cooking the 10-inch pizza within the confines of a microwave oven.

[0093] As depicted, D1 is the dimension that the food container 100′, required to contain the food item, and thus, is typically predetermined or known. For example in some embodiments D1 can be substantially equal to D4, in other embodiments D1 can differ from D4. In embodiments, D1 can range from about four inches to about fourteen inches; for example, D1 can be about 4 inches, about 5 inches, about 6 inches, about 7 inches, about 8 inches, about 9 inches, about 10 inches, about 11 inches, about 12 inches, about 13 inches, or about 14 inches, about 4 inches to about 13 inches, about 4 inches to about 12 inches, about 4 inches to about 11 inches, about 4 inches to about 10 inches, about 4 inches to about 9 inches, about 4 inches to about 8 inches, about 4 inches to about 7 inches, about 4 inches to about 6 inches, about 4 inches to about 5 inches, about 5 inches to about 14 inches, about 6 inches to about 14 inches, about 7 inches to about 14 inches, about 8 inches to about 14 inches, about 9 inches to about 14 inches, about 10 inches to about 14 inches, about 11 inches to about 14 inches, about 12 inches to about 14 inches, or about 13 inches to about 14 inches. Other sizes of D1 are also contemplated.

[0094] Dimension D2 represents the diagonal distance between opposite corners of an equivalent square container. For a container that is substantially square, D2 can be calculated using the equation:D⁢2=D⁢1·2

[0095] A reduced diagonal dimension, D3, facilitates the rotation of the container within the microwave, ensuring even heating of the food item.

[0096] In some embodiments, the diagonal dimension D2 can be reduced to D3 through the incorporation of chamfered corners. In some embodiments, the reduced dimension D3 can be defined by S1, which represents straight line chamfers between adjacent orthogonally oriented panels of the chamfered sidewall 106.

[0097] In embodiments, distance S1 can be adjusted to accommodate the dimensions of the food item. For example, distance S1 can range from zero (or near zero), in which angle Θ1, representing an angle between adjacent panels of the chamfered sidewall 106, measures approximately 0°, to S1max. As depicted angle Θ1 measures approximately 45°; however, in other embodiments, Θ1 can measure less than 45°. For example, a rectangular product (e.g., French bread, etc.), which might not require the full diagonal reduction that a 45° angle provides, could be accommodated using an angle Θ1 of approximately 30°.

[0098] In some embodiments, S1max can be determined according to the following formula:S⁢1max=D⁢11+2

[0099] Thereafter, D3 can be determined according to the following formula:D⁢3=S⁢1·(4+2⁢2)

[0100] Accordingly, in some embodiments, a diagonal dimension of an otherwise square food container 100′ can be reduced from an initial dimension D2 to a reduced diagonal dimension D3, through the use of chamfered corners 126 having a length S1, thereby enabling uninhibited rotation of the food container 100′ within the confines of a microwave.

[0101] As depicted in various embodiments, portions of the base panel 102, cover panel 104, and triangular-shaped areas 128, 130 may extend beyond the confines of the chamfered sidewall 106. Specifically, in some embodiments, a portion of the triangular-shaped areas 128, 130 overlaps with portions of the base panel 102 or cover panel 104, resulting in areas of increased material thickness. This configuration ensures that these areas remain structurally intact upon the separation of the lid portion 110, thereby enhancing the overall structural integrity of the food container 100′. In one specific embodiment, both the base panel 102 and the cover panel 104 adopt the form of an irregular octagon characterized by alternating internal angles of approximately 112.5° and 157.5°. It is noted that other geometrical configurations are also contemplated within the scope of this disclosure, providing flexibility in design to meet varying requirements.

[0102] Referring now toFIGS. 14-19, an alternative embodiment of a food container 200 is depicted in accordance with the disclosure. Similar to the previous embodiments, the food container 200 includes a base panel 202, a cover panel 204, and a chamfered sidewall 206, which may be constructed of a plurality of panels forming a polygonal shape. Collectively, the base panel 202, cover panel 204, and chamfered sidewall 206 define a sealed interior 208 for the containment of a food item. As depicted in FIGS. 18-19, a lid portion 210, defined by the cover panel 204 and chamfered sidewall 206, is capable of being opened to facilitate access to the interior 208. FIG. 18 depicts the lid portion 210 pivoted relative to the remainder of the food container (e.g., base panel 202, cover panel 204, and chamfered sidewall 206) by about 80 degrees, FIG. 19 depicts the lid portion 210 pivoted relative to the remainder of the food container by about 180 degrees. Further pivoting of the lid portion 210 relative to the remainder of the food container results in a substantially inverted food preparation configuration. In this configuration, a food preparation surface 212 of the lid portion 210, initially located on an inside facing surface of the lid portion 210 (as depicted in FIG. 17), is exposed to face upward away from the chamfered sidewall 206, resulting in the chamfered sidewall 206 being positioned below the lid portion 210, effectively lifting the food preparation surface 212 off a supporting surface (e.g., a turntable of a microwave, countertop, etc.) (e.g., similar to that depicted in FIG. 12).

[0103] FIG. 14 depicts a flat 260 representation of the food container 200, shown prior to its assembly into a three-dimensional configuration. Like the previous embodiment, the flat 260 may be fabricated from a paperboard material, although the utilization of alternative materials, such as plastics and composites is also contemplated. Each panel delineated by the flat 260 may be separated from an adjacent panel by a fold line or a bend defined by the flat 260. In some embodiments, the flat 260 may be precut to specified dimensions and distributed in a flat configuration, enabling subsequent assembly into the food container or another three-dimensional form as required. As depicted, the base panel 202 can be defined by a base panel edge 214. Similarly, the cover panel 204 can be defined by a cover panel edge 216. In some embodiments, both the base panel 202 and the cover panel 204 can be integral internal panels, each bordered entirely by segments of the flat 260 constituting the chamfered sidewalls 206.

[0104] In various embodiments, the base panel 202 and the cover panel 204 can exhibit similar geometrical shapes, representing the bottom and top, respectively, of the assembled food container 200. For example, the base panel edge 214 and the cover panel edge 216 may each be configured as an eight-sided figure, such as a regular octagon (e.g., comprising eight internal angles each measuring approximately 135°) (as depicted) or an irregular octagon (e.g., comprising internal angles alternating between approximately 112.5° and 157.5°, or any other two corresponding angles that total approximately 270°). It is contemplated that other polygonal configurations for the base panel 202 and the cover panel 204 may be employed, each varying in shape and size.

[0105] The chamfered sidewall 206 can be composed of multiple panels that operatively connect the base panel 202 to the cover panel 204, thereby forming the interior 208 in the folded configuration. Specifically, the chamfered sidewall 206 can include a first panel 218, a second panel 220, and sets of third and fourth panels 222A-B and 224A-B, respectively. These panels can collectively constitute four substantially orthogonally oriented sides of the chamfered sidewall 206. In the folded configuration, the first and second panels 218 and 220 can exhibit a single layer thickness, comprising a singular material layer, while the third and fourth panels 222A-B and 224A-B can exhibit a double layer thickness, comprising two or more material layers. Other thicknesses and layering configurations are also contemplated. For example, although the third and fourth panels 222A-B and 224A-B are depicted as having equal widths, certain panels can alternatively be designed as partial-width segments, exhibiting a partially overlapping width with their counterpart panels. Additionally, securement portion 232 may be configured to either partially or fully overlap with the first panel 218, allowing for greater flexibility in width and overlap configurations depending on the specific design requirements.

[0106] Each of the first, second, third, and fourth panels 218, 220, 222A-B, 224A-B can be interconnected along their respective edges by four chamfered corners 226A-D. The assembly of the various panels results in the formation of an eight-sided chamfered sidewall 206 positioned between the base panel 202 and the cover panel 204 to delineate the interior 208.

[0107] Additionally, as depicted, the flat 260 can define a plurality of triangular-shaped areas 228A-D, 229A-D, 230A-D, and 231A-D designed to fold in relation to the base panel 202 or cover panel 204. For example, the corresponding triangular-shaped areas 228A-D, 229A-D can be positioned adjacent to one another, separated by fold lines 227A-D. Similarly, corresponding triangular-shaped areas 230A-D and 231A-D can be positioned adjacent to one another, separated by fold lines 233A-D.

[0108] Further, in some embodiments, the flat 260 comprise a securement portion 232, which in some cases extends along one side of the flat 260. As illustrated, the securement portion 232 can be located along a first side 234 adjacent to the base panel 202 and triangular-shaped areas 231C, 231D. The securement portion 232 is designed to be affixed to an opposed, second side 236 of the flat 260, for instance, adjacent to the first panel 218 and chamfered corners 226A, 226B. Upon affixing the first side 234 to the second side 236, for example through the securement portion 232, the flat 260 transitions into a three-dimensional rectangular container with open ends (as depicted in FIG. 15), adjacent to the third panels 222A-B, and fourth panels 224A-B. In some embodiments, a food item may be positioned within the interior 208 while in this configuration and prior to the interior 208 being sealed.

[0109] Subsequently, as depicted in FIG. 16, the triangular-shaped areas 228A-D, 229A-D and 230A-D, 231A-D can be folded along fold lines 227A-D and 233A-D, such that adjacent triangular-shaped areas overlap with one another, to extend beyond the boundaries of the base panel edge 214 and the cover panel edge 216, which enables the chamfered corners 226A-D to be positioned between adjacent wall panels. In embodiments, the overlapping arrangement can enhance the structural integrity of the food container 200 by creating additional layers of material in areas of higher stress, particularly at the chamfered corners 226A-D, which are positioned between adjacent wall panels. In some embodiments, the overlapping triangular-shaped areas can be adhered or otherwise affixed to one another, further reinforcing the container and providing increased durability and resistance to deformation.

[0110] The chamfered corners 226A-D, or another portion of the chamfered sidewall 206, may incorporate securement tabs 238A-D, configured to attach to an adjacent panel within the chamfered sidewall 206, facilitating the creation of a continuous chamfered sidewall 206. In some embodiments, the triangular-shaped areas 228A-D, 229A-D and 230A-D, 231 A-D can be folded externally along fold lines such that the triangular folds are located on the exterior of the food exterior. In an alternate embodiment, the triangular-shaped areas 228A-D, 229 A-D and 230A-D, 231A-D can be folded internally along fold lines 227A-D and 233A-D such that the triangular folds are located in the interior of the food container 200.

[0111] With continued reference to FIG. 17, thereafter the triangular-shaped areas 228A-D, 229A-D and 230A-D, 231A-D can be folded over their respective chamfered corners 226A-D, such that no portions of the triangular-shaped areas 228A-D, 229A-D and 230A-D, 231A-D, base panel 202 or cover panel 204 extend beyond the boundaries of the chamfered sidewall 206. Further as depicted, various panels of the flat 260 can define a lid portion 210. In some embodiments, the lid portion 210 can be defined along its perimeter by a lid portion edge 240, which may comprise a score line or a line of perforations, enabling the separation of the lid portion 210 from other components of the food container 200.

[0112] In one embodiment, the lid portion edge 240 is defined by the cover panel 204, the first panel 218, and the second panel 220. In some embodiments, the lid portion edge 240 follows the contour of the cover panel edge 216, allowing the lid portion 210 to adopt a shape similar to that of the cover panel 204. Furthermore, the lid portion 210 may be sized slightly smaller than the cover panel 204, such that upon separation of the lid portion 210 from the cover panel 204 along the lid portion edge 240, a peripheral lip 242 of the cover panel 204 remains intact and in contact with the chamfered sidewall 206, thereby enhancing the structural integrity of the assembly. For instance, as depicted, the peripheral lip 242 may extend along at least six linear sides of the cover panel 204, for example, parallel to the panels of the chamfered sidewall 206, augmenting the stability of the food container 200 even after the detachment of the lid portion 210. As depicted, the lid portion 210 features chamfered corners that align with the form of the chamfered sidewall 206, resulting in the lid portion 210 closely matching the dimensions of the interior 208.

[0113] With additional reference to FIGS. 18-19, to facilitate the separation of the lid portion 210 from the cover panel 204, some embodiments include an extension of the lid portion edge 240 to at least the first panel 218, to define a lift tab 244, which is depicted as being defined by the first panel 218 (though it could also be defined by other panels such as the third or fourth panels 222A-B, 224A-B), is connected to the rest of the lid portion 210 by fold line or bend 245, and functions as a grip or handle. The lid portion edge 240 outlines the lid portion 210, including the lift tab 244, enabling a clean separation along the lid portion edge 240 when the lid portion 210 is detached from the cover panel 204. Specifically, a user may apply pressure to the lift tab 244, prompting its disengagement from the first panel 218 along the lid portion edge 240. The user can then grasp the lift tab 244 and exert an upward pulling force, away from the cover panel 204, facilitating further separation along the lid portion edge 240 as the lid portion 210 is progressively separated from the cover panel 204.

[0114] To facilitate the pivoting of the lid portion 210 relative to other portions of the food container 200, the lid portion edge 240 extends to at least the second panel 220, defining a hinge mechanism 246. The hinge mechanism 246 can serve as a pivot point, enabling the lid portion 210 to pivot relative to the rest of the food container 200. In one embodiment, the score line or perforations of the lid portion edge 240 extend through at least half of the width of the second panel 220, up to a first hinge line 248. The cooperative function of the first hinge line 248 and a second hinge line 250 allows the lid portion 210 to pivot to a substantially inverted state, bringing an exterior of the lid portion 210 into contact with an exterior portion of the base panel 202. Further, in some embodiments, an interior of the lid portion 210 can define a food preparation surface 212, which can comprise a susceptor material or include vents, apertures, or sipes.

[0115] Referring now to FIGS. 20-24, an alternative embodiment of a food container 300 is depicted in accordance with the disclosure. Similar to the previous embodiments, the food container 300 includes a base panel 302, a cover panel 304, and a chamfered sidewall 306, which may be constructed of a plurality of panels forming a polygonal shape. Collectively, the base panel 302, cover panel 304, and chamfered sidewall 306 define a sealed interior 308 for the containment of a food item. As depicted, a lid portion 310, defined by the cover panel 304 and chamfered sidewall 306, is configured to be opened to facilitate access to the interior 308. Furthermore, in some embodiments, the lid portion 310 can be rotated relative to the remainder of the food container (e.g., base panel 302, cover panel 304, and chamfered sidewall 306) from an initial food storage configuration to a substantially inverted food preparation configuration. In this configuration, a food preparation surface 312 defined by the lid portion 310, initially positioned within the interior 308, is repositioned to face away from base panel 302 and chamfered sidewall 306. This arrangement allows the chamfered sidewall 306 to form a supporting base for the lid portion 310 and food preparation surface 312, effectively lifting the food preparation surface 312 off a supporting surface (e.g., a turntable of a microwave, countertop, etc.).

[0116] FIG. 20 depicts a flat 360 representation of the food container 300, shown prior to its assembly into a three-dimensional configuration. Like the previous embodiment, the flat 360 can be fabricated from a paperboard material, although the utilization of alternative materials, such as plastics and composites is also contemplated. Each panel delineated by the flat 360 may be separated from an adjacent panel by a fold line or a bend defined by the flat 360. In some embodiments, the flat 360 may be precut to specified dimensions and distributed in a flat configuration, enabling subsequent assembly into the food container or another three-dimensional form as required. As depicted, the base panel 302 can be defined by a base panel edge 314. Similarly, the cover panel 304 can be defined by a cover panel edge 316. In some embodiments, both the base panel 302 and the cover panel 304 can be integral internal panels, each bordered entirely by segments of the flat 360 constituting the chamfered sidewalls 306.

[0117] In various embodiments, the base panel 302 and the cover panel 304 can exhibit similar geometrical shapes, representing the bottom and top, respectively, of the assembled food container 300. In certain embodiments, the base panel edge 314 and the cover panel edge 316 may each be configured as an eight-sided figure; however, it is contemplated that other polygonal configurations may be employed.

[0118] The chamfered sidewall 306 can be composed of multiple panels that operatively connect the base panel 302 to the cover panel 304, thereby forming the interior 308 in the folded configuration. Specifically, the chamfered sidewall 306 can include a set of first panels 318A-B, a second panel 320, a set of third panels 322A-B, and a set of fourth panels 324A-B. Collectively, these panels constitute four substantially orthogonally oriented sides of the chamfered sidewall 306.

[0119] Additionally, each of the first, second, third, and fourth panels 318A-B, 320, 322A-B, 324A-B can define tabs 327A-N extending laterally outward from the respective panels. For example, each of these tabs 327A-N can be operably coupled to its respective panel by a fold line or bend. As further depicted, the flat 360 can define a plurality of chamfered corners 326A-D, 325A-D, which can be respectively connected to the base panel 302 and cover panel 304 by a fold line or bend. In some embodiments, a precut line can be defined between the chamfered corners 325A-D, 326A-D and adjacent tabs 327A-N, thereby enabling bending of the chamfered corners 326A-D, 325A-D, (e.g., relative to the base panel 302 and cover panel 304) independently from manipulation of the tabs 327A-N. Although panels 318A-B are depicted as having equal widths, panel 318B can alternatively be configured as a partial width securement portion (e.g., having half of the width of panel 318A).

[0120] Collectively, the first panels 318A-B, second panel 320, third panels 322A-B, fourth panels 324A-B, and chamfered corners 325A-D, 326A-D can cooperate to form an eight-sided chamfered sidewall 306 positioned between the base panel 302 and the cover panel 304 to define the interior 308. For example, each of the panels comprising the chamfered sidewall 306 can be bent relative to the base panel 302 or cover panel 304 at a substantially orthogonal angle. Thereafter, the tabs 327A-N can be bent relative to their respective panels and joined to the chamfered corners 325A-D, 326A-D or to an adjacent tab 327A-N. Thereafter, the base panel 302 and the cover panel 304, each with a partially constructed chamfered sidewall can be fit together in a clamshell configuration to define the interior 308. In the folded configuration, the second panel 320 can exhibit a single layer thickness, comprising a singular material layer, while other panels comprising the chamfered sidewall 306 can exhibit at least a double layer thickness, comprising two or more material layers, adding to the structural integrity of the food container 300.

[0121] Various panels of the flat 360 can define a lid portion 310. In some embodiments, the lid portion 310 can be defined along its perimeter by a lid portion edge 340, which may comprise a score line or a line of perforations, enabling the separation of the lid portion 310 from other components of the food container 300. In one embodiment, the lid portion edge 340 is defined by the cover panel 304, the first panel 318A, and the second panel 320. In some embodiments, the lid portion edge 340 follows the contour of the cover panel edge 316, allowing the lid portion 310 to adopt a shape similar to that of the cover panel 304. Furthermore, the lid portion 310 may be sized slightly smaller than the cover panel 304, such that upon separation of the lid portion 310 from the cover panel 304 along the lid portion edge 340, a peripheral lip 342 of the cover panel 304 remains intact and in contact with the chamfered sidewall 306, thereby enhancing the structural integrity of the assembly. For instance, as depicted, the peripheral lip 342 may extend along at least six linear sides of the cover panel 304, for example, parallel to the panels of the chamfered sidewall 306, augmenting the stability of the food container 300 even after manipulation of the lid portion 310. As depicted, the lid portion 310 features chamfered corners that align with the form of the chamfered sidewall 306, resulting in the lid portion 310 closely matching the shape of the chamfered sidewall 306.

[0122] To facilitate the separation of the lid portion 310 from the cover panel 304, some embodiments include an extension of the lid portion edge 340 to an adjacent panel to define a lift tab 344, which is depicted as being defined by the first panel 318A (though it could also be defined by other panels). The lift tab 344 can be connected to other portions of the lid portion 310 by fold line or bend 345, and can be configured to function as a grip or handle.

[0123] The lid portion edge 340 outlines the lid portion 310, including the lift tab 344, enabling a clean separation along the lid portion edge 340 when the lid portion 310 is separated from the cover panel 304. Specifically, a user may apply pressure to the lift tab 344, prompting its disengagement from the first panel 318 along the lid portion edge 340. The user can then grasp the lift tab 344 and exert an upward pulling force, away from the cover panel 304, facilitating further separation as the lid portion 310 is progressively separated from the cover panel 304 along the lid portion edge 340.

[0124] To facilitate the pivoting of the lid portion 310 relative to other portions of the food container 300, the lid portion edge 340 can extend to at least the second panel 320 (or other adjacent panel) to define a hinge mechanism 346. The hinge mechanism 346 can serve as a pivot point, enabling the lid portion 310 to pivot relative to other portions of the food container 300. In one embodiment, the score line or perforations of the lid portion edge 340 extend through at least half of the width of the second panel 320, up to a first hinge line 348. The cooperative function of the first hinge line 348 and a second hinge line 350 enable the lid portion 310 to transition to substantially inverted state, bringing an exterior of the lid portion 310 into contact with an exterior portion of the base panel 302. Further, in some embodiments, an interior of the lid portion 310 can define a food preparation surface 312. In some embodiments, the food preparation surface 312 can comprise a susceptor material or include vents, apertures, or sipes.

[0125] Further, as depicted, first panel 318A can define a tear strip 347 (e.g., tear tape, zipper, etc.) configured to aid in initiating separation of the lid portion 310 from a remainder of the first panel 318A and cover panel 304. For example, in one embodiment active tearing of the tear strip 347 can release the lift tab 344 from the first panel 318A, enabling further manipulation of the lift tab 344 for separation of the lid portion 310 along the lid portion edge 340. Unlike the traditional use of tear strips, where tearing directly enables manipulation of a portion of the container to gain access to the food product, the embodiments depicted utilize the tear strip 347 to provide access to the lift tab 344. Once the tear strip 347 is actively torn, it releases the lift tab 344 from the first panel 318A, allowing the user to manipulate the lift tab 344 to separate the lid portion 310 along the lid portion edge 340. This feature can also be incorporated into food container 100 and food container 200, where a similar tear strip can enable access to the lift tab 144, 244, respectively, facilitating further manipulation and enhancing the ease of separating the lid portion from the cover panel.
