ABSTRACT:
A method and apparatus for blow molding in a single form-fill-seal operation a droplet dispenser bottle which delivers fluid in precise, uniform drops rather than the streamlets produced by similar bottles of earlier design. The method and apparatus is such that the desired amount of fluid is dispensed from the bottle regardless of how hard the bottle is squeezed. Depending on the needs of the packager, the method and apparatus can be made to form the orifice to precisely control droplet size and/or weight. The droplet dispenser bottle can be molded in virtually any shape desired to hold up to approximately two ounces of fluid.
