ABSTRACT:
An ice cream making apparatus includes an inner container having a first bottom formed with a first bottom opening, and an outer container surrounding the inner container to confine a coolant storing space therebetween. The outer container has a second bottom formed with a second bottom opening, and an outer rim extending along and upwardly from the second bottom opening. The outer rim has a shoulder extending radially and inwardly therefrom adjacent to the first bottom opening and confronting the first bottom of the inner container. A sealing ring is disposed between the shoulder and the first bottom of the inner container. A hollow tightening member extends through the first and second bottom openings, and abuts against the first bottom of the inner container and the outer rim so as to press the shoulder and the first bottom of the inner container to abut tightly against the sealing ring for preventing coolant from leaking out from the coolant storing space.
