A hot fillable plastic container having a body with a neck surrounding a dispensing aperture, the neck having an inner wall and an outer wall spaced therefrom to thereby provide a gap between the inner wall and outer wall which functions as a thermal insulation means. The neck is thus able to better withstand the temperatures encountered during the filling operation without deformation.
