Abstract:
To provide a grip that can be removed when unnecessary and is excellent in functionality and design.SOLUTION: Provided is a cylindrical member insertion structure for a metal thermal insulation container and grip structure, including: a container part 12 having an opening 21 at an upper end; a plug body 13 attached to the upper end of the container part 12 by screwing; and a grip member 15a as a cylindrical member 15, which is attached to an outer circumference of the container part 12. A receiving surface 23 is formed on the outer circumference of the container part 12 to reduce the diameter of the portion above it, and a contact 56 is formed on an inner circumference of an upper end of the grip member 15a that hits the receiving surface 23 from above. In addition, on an upper end face of the grip member 15a, a spiral convex 58 is formed with a receiving end face 57 behind a direction of rotation associated with the screwing of the plug body 13, and a lower end face of the plug body 13 is formed with a spiral concave corresponding to the spiral convex 58, and a butt end face is formed at a rear end of the spiral concave in the direction of rotation that is in contact with the receiving end face 57. The amount of screwing of the plug body 13 should be set so that the grip member 15a is pressed against the receiving surface 23 at the end of screwing to the container part 12.SELECTED DRAWING: Figure 2
