Abstract
Abstract A food or beverage thermoplastic container, to which a metal end can be attached without the necessity of flaring the thermoplastic sidewall of said container, which comprises thermoplastic container side walls having an upper edge and a lower edge and a ring clip which is bonded to said upper edge of the thermoplastic container sidewall by some suitable adhesive, the ring clip comprising a first wall having a first edge and a second edge, a second wall having a first edge and a second edge, the second wall being positioned outside of and adjacent to the first wall, a third annular wall positioned substantially perpendicular to the first wall and the second wall, and having an inner and outer edge, where the inner edge is connected to the first edge of the first annular wall, and the outer edge is connected to the first edge of the second annular wall, a fourth annular wall having an inner and outer edge, where the inner edge is connected to the first edge of the second annular wall, and wherein the first and second annular walls are arranged concentric to a central longitudinal axis.
