<p><P>PROBLEM TO BE SOLVED: To improve an impact resistance of a stainless steel-made heat insulating double structure bottle. <P>SOLUTION: The stainless steel-made heat insulating double structure bottle has a bottle body which has a double structure including an inner cylinder and an outer cylinder, in which a space between the inner cylinder and the outer cylinder reaching an upper end opening part from an lower end bottom part is sealed by holding it under a high degree of vacuum to make a heat insulating structure. In this bottle, the bottle has a structure in which almost whole outer surface except the opening part 14 of the bottle body 16 is covered by a sheathing body 20 made of a synthetic resin. In the bottle body and the sheathing body, there exists a supporting structure 28 in which the bottle body and the sheathing body are brought into contact with each other at least on the lower part, and in addition, on the upper part, an engaging part 21 engaging the opening part of the bottle body exists on the inside of the opening part of the sheathing body. By the supporting structure and the engaging part, the sheathing body has a pressing tendency to the bottle body to have an integrated constitution. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
