Abstract: A paper cooking utensil includes a paper cooking utensil formed into a food containing part made of a paper sheet. The paper sheet is sealed by an adhesive to form into each of the side sections and a bottom section, with the upper edge of each of the side sections being a flange section acting as a lip for holding the paper cooking utensil. Each of the flange sections is foldably connected along a folded line which folds down outwardly, the central area of the bottom section being attached with an aluminum foil sheet having a geometric shape. The aluminum foil sheet is fixed to the top surface of the bottom section by applying an adhesive only on two edges of the opposite sides, and the aluminum foil sheet is porous and has a thickness range of 10-50 microns with an area of no less than 60 square centimeters.

Abstract: A paper cooking utensil for induction cookers comprising a paper cooking utensil formed into a food containing part made of a paper sheet having its whole internal surface coated with a clear film and folded into a geometric cooking utensil, wherein the paper sheet is sealed together by an adhesive agent to form into each of the side sections and a bottom section, with the upper edge of each of the side sections being a flange section acting as a lip for holding the paper cooking utensil, and each of the flange sections is foldably connected together along a folded line which folds down outwardly, the central area of the bottom section being attached with an aluminum foil sheet having a geometric shape, wherein the said aluminum foil sheet is fixed to the top surface of the bottom section by applying an adhesive agent only on two edges of the opposite sides, and the aluminum foil sheet is porous and has a thickness range of 10-50 microns with an area of no less than 60 square centimeters, unless the induction

Abstract: This invention provides a food container made of a paper sheet with a base portion with four lateral edges connected by folding to the lateral side portions along the folding line. Between each lateral side portion is provided with a side flank which is divided into two portions along the folding line. The outer rim portions of a pair of opposite lateral side portions function as inner cover portions similar in shape to a cut end gable. The outer rim portions of another pair of opposite lateral side portions function as outer cover portions.
