Abstract

A microclean plastic bottle and handle system in which the bottle and handle are separately fabricated and joined at an appropriate time during the use of the bottle is disclosed. The bottle has an internal surface transverse cross section which is circular at each increment of its height between the bottle bottom and the top opening in order to minimize the possibility of creating contaminant-receiving crevices. The contours within the bottle are such that the interior is devoid of any inside corner exceeding about 60 degrees to further limit the potential for forming tiny crevices capable of containing microparticles of contaminating matter which are not readily removed by an interior washing process. An integral shoulder ring extends circumferentially about the bottle neck to serve as a detent for securely affixing the subsequently emplaced handle to the bottle. The handle includes a generally cylindrical bottle neck engaging portion and a yoke portion having three sides. The first and third sides each join the second side at an acute angle and converge toward one another and toward the neck engaging portion which they join more or less tangentially to provide a unitary structure.
