Abstract
A liquid dispensing package includes a container whose finish has an opposed pair of slots extending vertically from a free end thereof. A nozzle element with a dispensing passage extending therethrough is positioned within the finish and has an opposed pair of pins which extend into and through the slots of the finish to permit the nozzle element to translate, but not rotate, with respect to the finish, the translation being between a sealed, non-dispensing position and an unsealed, dispensing position. A cap element is rotatably affixed to the finish and has an opening in a top central panel which is aligned with the dispensing passage of the nozzle element. A skirt of the cap element has part helical grooves on its inside surface, and these grooves receive the free ends of the pins of the nozzle element. Thus, rotation of the cap element results in translation of the nozzle element. The opening of the central panel of the cap element has a frangible portion which is ruptured by contact with a boss at a free end of the nozzle element upon the first opening or attempted opening of the package to provide the package with tamper evident opening characteristics.
