    "9. The protective cover of claim 7, wherein the waterproof flexible outside shell is flame-resistant or fire-retarding, or both flame-resistant and fire-retarding.",
    "10. The protective cover of claim 7, wherein the outside shell comprises at least a front panel, two side panels, a rear panel, and two sloping panels coupled between the front panel, the two side panels, and the rear panel.",
    "11. The protective cover of claim 1, wherein the protective cover is configured to be placed on the cooking apparatus while the cooking apparatus is still at or near a temperature used for cooking.",
    "12. The protective cover of claim 1, wherein the at least one heat-resistant and thermally insulating material includes a felt-like material.",
    "13. The protective cover of claim 1, wherein the at least one heat-resistant and thermally insulating material includes one or more of: FR Rayon, preoxidized acrylonitrilefiber, polyacrylonitrile fiber, meta-aramid synthetic fiber, para-aramid synthetic fiber, another aramid fiber, and asbestos.",
    "14. The protective cover of claim 1, wherein the cooking apparatus is one of: a barbeque grill, a rotisserie, a fryer, and a boiler.",
    "15. The protective cover of claim 1, wherein the flexible inside shell is configured to prevent the protective cover from melting and burning when in contact with the hot portion and to cause the protective cover to dissipate heat from the hot portion over a surface area larger than a surface area corresponding to the hot portion; wherein the hot portion corresponds to the cooking apparatus being at or near a temperature used for cooking; wherein the waterproof flexible outside shell has a waterproof inner coating and is flame-resistant or fire-retarding, or both flame-resistant and fire-retarding; wherein the waterproof flexible outside shell comprises at least a front panel, two side panels, a rear panel, and two sloping panels coupled between the front panel, the two side panels, and the rear panel; wherein the protective cover is configured to be placed on the cooking apparatus while the cooking apparatus is still at or near a temperature used for cooking; and wherein the cooking apparatus is one of: a barbeque grill, a rotisserie, a fryer, and a boiler.",
    "16. The protective cover of claim 1, further comprising a plurality of third seams, wherein each of said third seams joins together a respective one of the two or more waterproof flexible panels of the waterproof flexible outside shell and a respective one of the two or more flexible panels of the flexible inside shell.",
    "17. The protective cover of claim 16, wherein the plurality of third seams joins the flexible inside shell to the waterproof flexible outside shell in a manner that leaves an air gap between the flexible inside shell and the waterproof flexible outside shell.",
    "18. The protective cover of claim 17, wherein the plurality of third seams includes a seam that forms a seal between the flexible inside shell and the waterproof flexible outside shell to prevent infiltration of extraneous substances into the air gap.",
    "19. The protective cover of claim 17, wherein the plurality of third seams includes a seam that stitches together an edge of the respective one of the two or more flexible panels of the flexible inside shell and a middle portion of the respective one of the two or more waterproof flexible panels of the waterproof flexible outside shell.",
    "20. The protective cover of claim 16, wherein the two or more waterproof flexible panels of the waterproof flexible outside shell include at least a front panel, a first side panel, a second side panel, and a rear panel; and wherein the two or more flexible panels of the flexible inside shell include at least: a respective front panel that is joined by one or more of the third seams to the front panel of the waterproof flexible outside shell; a respective first side panel that is joined by one or more of the third seams to the first side panel of the waterproof flexible outside shell; a respective second side panel that is joined by one or more of the third seams to the second side panel of the waterproof flexible outside shell; and a respective rear panel that is joined by one or more of the third seams to the rear panel of the waterproof flexible outside shell.",
    "21. A method of protecting a cooking apparatus, the method comprising: providing a protective cover to be placed on the cooking apparatus while the cooking apparatus is at or near a temperature used for cooking, wherein the protective cover comprises: a waterproof flexible outside shell conforming generally to a shape of the cooking apparatus and having an underside, wherein the waterproof flexible outside shell includes two or more waterproof flexible panels; a flexible inside shell coupled to the underside of the waterproof flexible outside shell, the flexible inside shell comprising at least one heat-resistant and thermally insulating material disposed to contact a hot portion of the cooking apparatus when the protective cover is placed thereon, wherein the flexible inside shell includes two or more flexible panels that comprise the at least one heat-resistant and thermally insulating material; a plurality of first seams, wherein each of said first seams joins together respective two of the two or more waterproof flexible panels of the waterproof flexible outside shell; and a plurality of second seams, wherein each of said second seams joins together respective two of the two or more flexible panels of the flexible inside shell.",

  "description_excerpt": "The disclosure relates, generally, to cooking apparatus, and more particularly, to protective covering devices for barbecue grills and other cooking apparatus.\n\nConventional covers protect barbecue grills and other outdoor cooking apparatus against sun, rain, snow, dust, rodents, tree sap, spills, and the like.\n\nAfter a barbecue grill has been used for cooking, a conventional protective cover can be placed over the grill only once the grill has cooled down to a temperature sufficient to avoid melting, deforming, or otherwise damaging the cover, or causing the cover to adhere to the grill.\n\nEmbodiments of the present disclosure provide protective covers for use with barbecue grills fueled by propane, natural gas, and charcoal, as well as rotisseries, roasters, turkey fryers, seafood boilers, smokers, burners, and other indoor and other outdoor cooking apparatus. A protective cover consistent with embodiments of the disclosure can safely be applied to cover a hot grill or other cooking apparatus, immediately after the use of such apparatus for cooking.\n\nIn one embodiment, the disclosure provides a protective cover including a waterproof flexible outside shell having an underside, and at least one inside flexible shell coupled to the underside of the outside shell. The inside shell includes at least one heat-dissipating material.\n\nIn another embodiment, the disclosure provides a method for covering a hot cooking apparatus.",
