Abstract
A cup structure with heat isolation effect is disclosed, thereby, if two cups according to the present invention are overlapped, the combined cups have a preferred heat isolation effect. The bottom of the cups are installed with respective isolation elements. When th user overlaps two cups, he (or she) can rotate the inner cup with an angle, so that the isolation element of the inner cup can rest against the isolation element of the outer cup. Therefore, by the shielding the isolation element of the outer cup, the bottom of the inner cup can not rest against the bottom of the outer cup, thus a space is formed therebetween. Especially, the handle on the lateral side of the cup has a preferred effect. Therefore, it a hot food is filled into the cup, because of the isolation of the space, the hot temperature of the inner cup can not be transferred to the outer cup and thus the good heat isolation effect is attained.
