Abstract: A pressurized fluid package comprising a plastic container and a base. The oriented plastic container includes a cylindrical side wall, a neck, a neck finish on the upper end of the neck for receiving a closure, and a hemispherical bottom wall. The plastic base includes a seating area for engaging a surface on which the package is supported, and a peripheral wall extending upwardly and outwardly and terminating in an annular free edge portion defining an inner primary support area engaging a complementary area of the hemispherical wall of the container to provide primary and sole support axially for the container in the base. The base also has a second contact area for receiving adhesive to bond the hemispherical bottom wall of the container.
