Abstract: A base for a plastic container defining a central longitudinal axis. The base includes an annular standing ring portion defining a standing surface. The base includes a substantially cylindrical ring portion extending in a direction substantially perpendicular to the standing surface. The base further includes a substantially concave dome portion extending inwardly from the substantially cylindrical ring portion to the longitudinal axis. The concave dome portion of the base includes a first plurality of substantially triangular panels circumferentially spaced around the longitudinal axis, and a second plurality of substantially triangular panels circumferentially spaced around the longitudinal axis. At least a portion of each of the second plurality of substantially triangular panels is circumferentially and longitudinally offset from the first plurality of substantially triangular panels. A container preform and method of hot filling a plastic container are also disclosed.

Abstract: A container includes a hollow body having a finish extending from the body. The finish has an open end, at least one external thread for securement of a closure, and a pair of spaced external circumferential flanges on a side of the thread remote from the open end of the finish. A bale handle includes a ring having resilient internal tabs captured beneath the lower of the flanges remote from the open end of the finish, and a handle extending from the ring for carrying the container. The upper flange, which preferably has a greater outside diameter than the lower flange, has an undersurface that is free of obstruction from the bale handle and therefore is adapted to perform support functions for the container after attachment of the bale handle to the container finish.

Abstract: A hot-fill container is of one-piece plastic construction that includes a base, a sidewall extending from the base, a dome connected to the sidewall and a neck finish extending from the dome. The sidewall has an hourglass shape as viewed in side elevation with ends connected to the base and the dome. The sidewall includes a circumferential series of vacuum panels that are flexible inwardly with respect to the remainder of the sidewall. The vacuum panels preferably are rectangular as viewed in side elevation and concave as viewed tangentially of the container.

Abstract: A plastic container includes a finish, a shoulder extending from the finish, a closed base, and a sidewall connecting the shoulder to the base. The sidewall is of blow molded construction and generally uniform wall thickness. The sidewall has an array of circumferentially spaced longitudinally extending radially recessed channels, and an array of axially spaced circumferentially extending radially recessed channels intersecting the longitudinally extending channels. The longitudinally extending channels have radially inner portions that lie on an hourglass-shaped common surface of revolution around the axis of the container sidewall. In the preferred embodiments of the invention, a plurality of axially and circumferentially spaced land areas are disposed in spaces between the intersecting longitudinally and circumferentially extending channels, with the land areas lying on a common surface of revolution, preferably a cylindrical surface of revolution, around the axis of the container sidewall.
