ABSTRACT:
A container having a unitary hollow receptacle and closure is formed according to a process is which an injection molding step forms a preform of thermoplastic material having (1) a hollow body, (2) a closure base at one end of the hollow body to define an opening into the hollow body, and (3) a closure cover spaced from the closure base opening but connected to the closure base. The process further includes blow molding the preform hollow body to form the hollow receptacle so that it extends from the closure base and has a configuration different than the preform hollow body.
