In addition, the presence of the jelly-like cold insulator between the inner and outer cups has a remarkable cooling effect as compared with the conventional one. According to the second aspect, since paper or cloth having water absorbency is attached to the outer surface of the side wall of the inner cup, a more excellent cooling effect is exhibited in combination with the cooling material at the bottom. According to the third aspect of the present invention, the heat insulating sheet is fitted on the bottom surface of the outer cup and the inner peripheral surface of the side shell. According to the fourth aspect, when the inner cup and the outer cup are fixed, the lower end of the inverted U-shaped bent portion provided at the upper part of the inner cup is in close contact with the outer cup without resistance, and it is possible to prevent an increase in the internal pressure in the space between the two. Contribute to improvement of mug productivity,
Moreover, it is structurally safe. Furthermore, since the inner cup is made of stainless steel, it is not damaged even after many uses and is extremely sanitary. According to the fifth aspect, when the jelly-like cold insulator is frozen in the freezer, the volume is increased, and a force for pushing up the inner cup is generated from the press-fit welding portion of the outer cup. This annular groove prevents this and further increases the structural strength.
