[0046] FIGS. 1-4 depict the improved combination cookware system 100 in a closed configuration, while FIGS. 8 and 9 depict the improved combination cookware system 100 in an open configuration as described in greater detail below. The system 100 includes a first portion 110, such as a skillet, and a second portion 120, such as an everyday fry/sauté pan. In some cases, the first and second portions are referred to collectively as “pans” and the second portion may be referred to as a hybrid pot. Each of the first and second portions 110, 120 include a cooking surface 112, 122 and a raised edge 114, 124 extending from their respective cooking surfaces 112, 122. The raised edges 114, 124 extend along a perimeter or a circumference of their respective portions 110, 120. Based on the orientation shown in FIGS. 1-4, the raised edge 114 of the first portion 110 extends downwardly from the cooking surface 110, while the raised edge 124 of the second portion 120 extends upwardly from its cooking surface 122. The first and second portions 110, 120 shown have generally dome-like shapes with circular openings; however, the shape of the portions and their respective openings can vary to suit a particular application and may include round, ovoid, polygonal, or combinations thereof, so long as the raised edges 114, 124 are generally aligned in the closed configuration, as described herein.

[0047] The first and second portions 110, 120 each include a gripping handle 116, 126 engaged with and extending outwardly from their respective raised edges 114, 124. The gripping handles 116, 126 may include flanges 150a, 150b for coupling to their respective portions via, for example, rivets, screws, or welding. In addition, the first and second portions 110, 120 each include a pivot handle 118, 128 engaged with and extending outwardly from their respective raised edges 114, 124. The pivot handles 118, 128 are typically located opposite of (i.e., diametrically opposed to) the gripping handles 116, 126; however, their positioning may vary to suit a particular application. The pivot handles 118, 128 may also include flanges 152a, 152b for coupling to their respective portions via, for example, rivets, screws, or welding.

[0048] The first portion 110 and the second portion 120 are engageable with one another to form the combination cookware system 100, which in some embodiments acts as a dutch oven. In some embodiments, the first portion 110 and the second portion 120 are engageable such that the raised edges 114, 124 of the first and second portions are in at least partial contact with one another or are close enough together that there is essential little to no gap between the two edges 114, 124. In some embodiments, a slight gap may be present to allow for, for example, venting from the closed cookware system 100. Additionally, the raised edges 114, 124 may include substantially flat top surfaces 140, 142 however, in some embodiments, the top surfaces 140, 142 may include mating structure (e.g., a trough on one top surfaces and a rib on the other top surface that is sized and shaped to interface with the trough) to, for example, assist with engagement and alignment between the two portions 110, 120.

[0049] In this closed configuration, the gripping handles 116, 126 of the first and second portions 110, 120 are configured and arranged to nest with each other to form a unified and ergonomic gripping handle Nesting of the gripping handle 116 of the first portion 110 in the gripping handle 126 of the second portion 120 facilitates registration between the two portions and allows for the unified gripping handle to be gripped by one hand of the user. In some embodiments, the gripping handle 126 of the second portion 120 defines a recess 146 or similar structure on a top surface thereof (see also 246 in FIG. 5), while the gripping handle 116 of the first portion 110 has a protuberance 144 or similar structure on a bottom surface thereof (see also 244 in FIG. 6), where these two structures 144, 146 are sized and shape to be coupled together. In some embodiments, the gripping handles 116, 126 may be coupled together via a slight interference fit or a snap-fit such that handles 116, 126 tend to stay coupled until manually separated (e.g., a user lifts the top handle 116 to raise the first portion 110. In some additional examples, the gripping handle 116 of the first portion 110 may be longer than the gripping handle 126 of the second portion 120, so as to enable gripping of or interaction with just the gripping handle 116 of the first portion 110 in order to move the first portion 110 relative to the second portion 120 and/or to pivot the first portion 110 away from the second portion 120.

[0050] Also in the closed configuration, the pivot handles 118, 128 of the first and second portions 110, 120 are configured and arranged to engage with one another to form a type of pivot joint or engagement portion 130. The pivot joint 130 allows for the gripping handle 116 of the first portion 110 to be moved away from the gripping handle 126 of the second portion 120 into an open configuration, while maintaining registration between the two pivot handles 118, 128. The structure and registration between the two pivot handles are shown and described in greater detail with respect to FIGS. 7A-7C.

[0051] FIGS. 5 and 6 depict embodiments of individual cookware portions 210, 220 in greater detail. As shown in FIG. 5, the first portion 210 is shown in an inverted orientation insofar as the “bottom” of the cookware is depicted versus the orientation shown in FIGS. 1-4. The first portion 210 has a generally shallow, dome shape; however, other shapes are contemplated and considered within the scope of the invention. The first portion 210 includes a cooking surface 212 with a raised edge 214 extending upwardly therefrom (downward relative to its assembled orientation) and terminating at a top surface 240 thereof. The raised edge 214 has a generally curved shape; however, the raised edge 214 could have a substantially vertical planar shape to suit a particular application. The first portion 210 also includes a gripping handle 216 and a pivot handle 218 arranged as described above with respect to first portion 110. The gripping handle 216 is attached to the raised edge 214 via a flange 250a and includes structure 244 configured to mate with a corresponding structure on another handle. The pivot handle 218 extends from the raised edge 214 opposite of the gripping handle 216 and is also attached via a flange (not shown). The pivot handle 218 also includes structure 232 configured to mate with a corresponding structure on another handle to form a pivot joint. In some embodiments, the pivot handle 218 includes additional structure 236 for engaging and/or securing itself to the other pivot handle.

[0052] FIG. 6 depicts a second portion 220 with a generally dome shape, typically deeper than the dome of the first portion of FIG. 5. However, as with the first portion 210, other shapes are contemplated and considered within the scope of the invention. The second portion 220 includes a cooking surface 222 with a raised edge 224 extending upwardly therefrom and terminating at a top surface 242 thereof. The raised edge 224 has a generally curved shape; however, the raised edge 224 could also have a substantially vertical planar shape to suit a particular application. The second portion 220 also includes a gripping handle 226 and a pivot handle 228 arranged as described above with respect to second portion 120. The gripping handle 226 is attached to the raised edge 224 via a flange 250b and includes structure 246 configured to mate with a corresponding structure on another handle. The pivot handle 228 extends from the raised edge 224 opposite of the gripping handle 226 and is also attached via a flange (not shown). The pivot handle 228 also includes structure 234 configured to mate with a corresponding structure on another handle to form a pivot joint. In some embodiments, the pivot handle 228 includes additional structure 238 for engaging and/or securing itself to the other pivot handle.

[0053] FIG. 7A is an enlarged view of the engagement portion/pivot joint 330 of a combination cookware system. As shown, the pivot handle 318 of the first, or upper, portion 310 engages the pivot handle 328 of the second, or lower, portion 320 to form a pivot joint, such as a ball and socket joint, a saddle joint, a hinge joint, a gliding joint, a condyloid joint, or the like. Generally, one pivot handle forms the stud portion of the joint, while the other handle forms the socket portion of the joint.

[0054] FIG. 7B depicts the pivot handle 328 of the second portion removed therefrom. FIG. 7C depicts the pivot handle 318 of the first portion 310 removed therefrom Similar to the handles described above, the handles 318, 328 may include flanges 352a, 352b for attaching the pivot handles to their respective portions. In some examples, a ball and socket joint may be formed by the interaction of the two pivot handles 318, 328. For example, the pivot handle 328 of the second portion may include a recessed flange or socket 334, which may receive and act as guide for a protuberance or stud 332 portion of the pivot handle 318 of the first portion. The interface between the pivot handles 318, 328 forms the pivot joint 330. The stud 332 rests in and is levered against the socket 334 during a pivoting action. In some embodiments, a protuberance or “tongue” 336 may also be present on the pivot handle 318 of the first portion, which can engage with a channel 338 on the pivot handle 328 of the second portion to further assist in the engagement and alignment between the two pivot handles 318, 328.

[0055] FIGS. 8 and 9 depict combination cookware systems in open configurations. As shown in FIG. 8, gripping handle 116 is raised relative to gripping handle 126, resulting in the raising of the first portion 110 relative to the second portion 120 and about the pivot joint 130.

[0056] The combination cookware system 400 of FIG. 9 is substantially similar to the system 100 of FIG. 8, but with a lid 460 incorporated therein. The lid 460 is universally sized to fit both the first portion 410 and the second portion 420. For example, the lid 460 may be configured and arranged to engage a top edge 440 of the raised edge of the first portion 410 or a top surface 442 of the raised edge of the second portion 420 opposite their respective cooking surfaces. As shown in FIG. 9, the lid 460 is engaged with the top surface 442 of the second portion 420 enclosing the second portion. The lid 460 includes structure 464 configured to engage the first portion 410, which allows the lid 460 to be arranged between the first portion 410 and the second portion 420, such that the lid 460 engages the raised edges of one or both the first and second portions 410, 420 and acts as a barrier between the two portions. Alternatively, the first portion 110, 410 may act as a lid to the second portion 120, 420 and vice versa.

[0057] In some embodiments, the first portion 110, 210 comprises a first material and the second portion 120, 220 comprises a second material, where the first and second materials may be the same material or different materials. In various embodiments, the first and/or second materials may be selected from carbon steel, cast iron, multi-ply stainless steel (e.g., 24 gauge, series 305, 316, or 410) with an aluminum (e.g., a 6061 or 1060 aluminum alloy) core, a ferrous metal with stainless steel cladding, copper, titanium and/or the like, with or without a non-stick coating.

[0058] In certain embodiments, for example where the first material is carbon steel and the second material is a multi-ply stainless, the portion comprising the carbon steel material acts as an energy source for the other portion comprising the multi-ply stainless steel material due to the conductive nature of the aluminum layer of multi-ply stainless steel and the heat retentive properties of carbon steel, cast iron, and/or other ferrous metals. The use of different materials between the first and second portions, promotes optimal cooking, for example, slow cooking, keeping food warm, etc., as needed and/or as appropriate.

[0059] The first and second portions, their handles, and other components thereof may be manufactured via any conventionally known manufacturing process, such as casting, forging, stamping, and machining, with or without a coating or a mechanical finishing treatment (e.g., polishing).

[0060] The size of the portions will vary to suit a particular application and may range from about 6 inches (in.) in diameter (D) to about 20 in. in diameter (D) (or equivalent area for non-circular cookware), including, for example, 8 in., 10, in., 12 in., and 14 in. The height (X1) of the raised edge 114 of the first portion may range from about 1.0 in to about 2.5 in., while the height (X2) of the raised edge 124 of the second portion may range from about 2.0 in. to about 4.0 in.
