A seal device includes a first, inverted cup-shaped member and a second cup-shaped member within which the first member is disposed. The open, lower end of the first member is provided with a radially outwardly projecting annular flange for engaging the inner peripheral wall of the second member whereby a blind, annular recess is defined by the first and second members for accommodating one end of a hollow container. The peripheral walls of the seal members, as well as the flange of the first member, thus engages at least two primary surfaces of the container thereby defining a three-point, plug type seal therefor. The second member is also provided with a frusto-conical skirt portion which serves as a base or foundation for the container, and if desired, the first and second members may be integrally formed.
