Abstract
A composite container comprising a rigid cylindrical sidewall, an end closure integrally attached to the sidewall, a product-compatible liner disposed within said sidewall, and a cutter element, carried between the sidewall and the liner, for rupturing the liner to permit passage of product therethrough. The end closure is formed of a distal end portion of the sidewall folded into a plurality of interconnected triangular segments disposed transverse the principal axis of the container and arranged to be reformable into a pouring spout. A grasping element is attached to both the cutter element and the end closure, such that the end closure may be opened, the pour spout erected and the liner ruptured in a single operation.
