Abstract
A package including a container assembly, such as a tube having a dispenser spout, and a closure assembly having a concealed hinge, is provided for use in dispensing a consumer product such as toothpaste or medicinal ointment. The concealed hinge of the closure assembly permits a lid to be opened up to 180.degree. away from an associated closure base to provide maximum access to the container assembly to which the closure assembly is assembled. The closure assembly, including the lid and base, is capable of being molded in a single mold cavity and having maximum ease of opening and closing together with either one or two seals.
