When assembling the heat insulating container, place the vacuum insulated double container 2 inside the exterior body 3 and close the flange 2c.
After placing the shoulder body on the open end surface 3a of the exterior body 3, the shoulder body 4 may be aligned and the forcible fitting protrusion 18 of the shoulder body may be forcibly fitted into the annular groove 9 of the exterior body 3.
If this continues, the entire weight of the exterior body 3, the double container 2, and the items placed inside will be applied only to the fitting part between the shoulder body 4 and the exterior body 3, and the exterior body will come off when subjected to impact. The problem arises that the body 3 and the double container 2 fall. In order to solve this problem, the present invention provides pin holes 20 and 21 in the ear part 14 for attaching the hanging cord and the convex part 12 of the exterior body, respectively, and passes the roll pin 22 through the pin holes 20 and 21.
The shoulder body 4 and the exterior body 3 are fixed.

Further, in this embodiment, the roll pin 22 rotatably supports the leg portion 26 of the lid lock member 25, and the roll pin 22 is also used as a hinge pin. A recess 27 for accommodating the projection 5a formed on the lid 5 is formed in the locking portion of the lid lock member 25, and a locking projection 28 is formed on the lower side of the bottom wall forming the recess 27. When the locking protrusion 28 pushes the lid lock member 25 toward the shoulder body and locks the lid 5, it rides over the chevron-shaped protrusion 29 provided on the lower strap attaching ear 14 of the shoulder body 4 and forcibly engages with the protrusion 29. The lid 5 is then locked.

In addition, 30 is a soup bowl, 34 is a rice bowl, and 36 is a vegetable container. A seal ring 31 is disposed at the center of the seal ring 31 to prevent juice leakage, while a vent hole 32 and the vent hole are closed in order to prevent the interior from being depressurized due to a drop in the temperature of the juice and becoming unable to remove the lid 30b. An automatic pressure reduction prevention valve 33 is installed. This automatic depressurization prevention valve 33 is formed of an elastic material into an umbrella shape, and seals the inside of the juicer when the pressure is normal or increases, and when the pressure is reduced, air enters through the vent 32 to prevent the internal pressure from decreasing. To prevent.
Further, the rice bowl 34 consists of a main body 34a and a lid 34b, and the lid 34b is provided with a heat insulating material 35 inside to prevent heat from the cooked rice etc. from being conducted to the vegetable container 36. . Similarly, the vegetable container 36 also includes a main body 36a and a lid 36b.
