Abstract
A blow-molded container (10) having a closure flap (14) formed of compressed material (32) integral with the container (10). Preferably, the container body (12) has a normally-closed fill port (16) and a dispensing port (18) which can be selectively opened and closed by the closure flap (14). The closure flap 14 is provided with multiple hinges (34, 38, 50) to allow the closure flap (14) to fold reversely upon itself and to allow the dispensing port (18) to be opened and closed while the fill port (16) remains closed.
