The device 10 is preferably intended for grilling or broiling meats or other foodstuffs 60. The device 10 includes an enclosure 20 defining an interior space 21 for receiving said foodstuffs 60 and retaining heat provided by a subjacent cooking surface 65 or appliance. The enclosure 20 provides a closed structure comprising a base 30, an upwardly arching wall structure 25, an open front archway 22, a solid rear panel 23, and a door 40. The enclosure 20 is envisioned to comprise approximate dimensions of twelve (12) inches in width, ten (10) inches in depth, and ten (10) inches in height; however, it is understood that the device 10 may be introduced in a variety of sizes based upon particular foodstuffs 60 to be cooked, and as such should not be interpreted as a limiting factor of the device 10.
The door 40 comprises a flat arched-shape structure corresponding to an inner perimeter opening of the front archway 22, thereby enabling snug insertion within a lip portion 24 of said front archway portion 22 to support and secure the door 40. The base 30 provides spacing between the foodstuffs 60 and the cooking surface 65 while allowing fat and other liquids to drain from the foodstuffs 60 during a cooking process via a plurality of drainage apertures 32. The enclosure 20 includes an elongated arch-shaped profile and is preferably constructed of a semi-flexible aluminum foil material which provides efficient thermal conduction and a safe cooking container. The enclosure 20 includes an open front archway 22 along an end portion and an opposing solid rear panel 23.
The enclosure 20 preferably comprises an assembly of aluminum panels and wire frame portions 27 being assembled using common metal joining processes such as, but not limited to: various welding processes, adhesives, soldering, crimping, and the like, to form a unitary structure. Bottom edge portions of the previously mentioned wall structure 25 are affixed to respective outer edges of the base 30. The open front archway 22 and rear panel 23 portions are constructed using a rigid internal metal wire frame 27 being covered over by an aluminum foil material (see FIG. 3). Furthermore, said front archway 22 and rear panel 23 portions are interconnected via attachment to respective edge portions of the wall structure 25. The front archway 22 further includes a lip 24 which protrudes inwardly perpendicularly from the interior perimeter of the front archway 22 in order to support and prevent the door 40 from moving into an interior space 21 of the enclosure 20.
The front archway 22 comprises a door latch 26 at a top center location along an inner edge. The door latch 26 includes a convex protruding portion that allows a user to secure the door 40 within the front archway 22 by engaging said door latch 26 with a corresponding door notch portion 42 of said door 40. The door notch 42 comprises a corresponding concave profile which is retained within the latch 26 via a friction fit.
The base 30 and wall structure 25 portions comprise a plurality of aligned wall fold lines 28a and base fold lines 28b, respectively. The fold lines 28a, 28b allow the enclosure 20 to pivot and fold compactly inward, thereby selectively expanding and contracting the interior space 21 of the enclosure 20.
The base 30 of the device 10 includes a rectangular structure which supports the wall structure 25 and provides a spacing means between the interior space 21 of the device 10 and the cooking surface 65. The base 30 has a length and width corresponding to the bottom perimeter edges of said wall structure 25 being affixed along respective perimeter edges. The base 30 is constructed using semi-rigid aluminum panels formed around an inner filler material 50 and is capable of supporting approximately twenty pounds (201b) of foodstuffs 60 (see FIG. 2).
Referring now to FIG. 2, a longitudinal section view of the device 10 taken along section line A-A, according to a preferred embodiment of the present invention, is disclosed. The base 30 comprises a box-like structure preferably constructed of semi-rigid aluminum foil panels forming an interior volume containing a filler material 50. Said base 30 further comprises a plurality of drainage apertures 32 arranged in an equally-spaced manner along top and bottom surfaces. Each drainage aperture 32 is approximately one millimeter (1 mm) in diameter and arranged in a square matrix pattern with said drainage apertures 32 being approximately five millimeters (5 mm) center-to-center. The drainage apertures 32 are to be sized and spaced so as to provide effective drainage of fat particles and liquids away from the foodstuffs 60 during the cooking process. The base 30 allows said fat and drained liquids to flow out of the device 10 while inhibiting smoke from rising upward into the interior space of the device 10, possibly causing contact with, and/or absorption of, said smoke into said foodstuffs 60. Said filler material 50 provides drainage downwardly through the base 30 as well as internal structural integrity to support loading of the foodstuffs 60. Said filler material 50 is envisioned to comprise materials such as, but not limited to: roll-bonded clad metal, sintered metal, densely spun aluminum wire, or the like.
The fold line portions 28a, 28b of the base 30 and wall structure 25 portions are arranged in an equally-spaced and parallel manner extending in a lateral direction. Each fold line 28a, 28b allows the enclosure 20 to pivot and fold compactly inward along creases arranged in an alternating pattern such that the body 20 can be collapsed in an “accordion” manner for purposes of compact packaging and storage. The base fold lines 28b are spaced evenly along the length of the base 30 such that they are aligned with corresponding wall fold lines 28a. 
The front archway 22 and rear panel 23 portions comprise semi-rigid structures comprising internal wire frame portions 27 positioned within corner portions and covered with aluminum foil panels. Said front archway 22 and rear panel 23 also contain a filler material 50 in a similar manner as the aforementioned base 30.
The door 40 provides similar construction as the front archway 22 and rear panel 23 portions comprising a metal wire frame 27 surrounded by aluminum foil panels and containing a filler material 50. Closing the door 40 isolates an interior space 21 of the enclosure 20, thereby preventing unwanted convective cooling of the interior space 21 during cooking. The door 40 further comprises an “L”-shaped protruding grip 44 at a top front edge which provides a means for a user to open the door 40 as desired. The respective foil coverings of the door 40 and front archway 24 are connected along bottom edges forming an integral hinging edge feature 52, thereby securing said door 40 to the enclosure 20.
Referring now to FIG. 3, an isolated view of wire frame portions 27 of the device 10, according to a preferred embodiment of the present invention, is disclosed. The open front archway 22 and rear panel 23 portions are constructed using a rigid internal metal wire frame 27 comprising parallel lengths of rigid wire being subsequently covered over using an aluminum foil material (see FIG. 1).
It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
