Abstract:
1. A thermally insulating member comprising a plane sheet including two ends spaced from each other in a length direction and two sides spaced from each other in a thickness direction perpendicular to the length direction and extending between the two ends, with the plane sheet including a plurality of rows of slits between the two ends of the plane sheet, with each of the plurality of rows of slits extending from one of the two sides through another of the two sides of the plane sheet, with two adjacent rows of slits spaced from each other in the length direction by a first spacing, with two adjacent slits in a same row of slits spaced from each other in a width direction perpendicular to the length and width directions by a second spacing, with the first spacing larger than the second spacing, with a thermally insulating strip defined between two adjacent rows of slits, with a stretchable rib formed between two adjacent slits in the same row of slits, with each of the two ends of the plane sheet being a coupling portion free of the slits.
