Patent attributes
A bottle push-pull aseptic dispenser cap comprising a guide-body having a reference axis and designed to be coupled to the mouth of a bottle; the guide-body being provided with a tubular shaped inner chamber closed at the bottom, and with through openings designed to place the inner space of the bottle in communication with the inner chamber. The cap further comprises a shutter-nipple which is coupled in an axially sliding manner to the guide-body so as to translate axially inside the inner chamber along the reference axis, between a retracted position, in which the shutter-nipple closes the through openings in a fluid-tight manner, and an extracted position, in which the shutter-nipple projects cantilevered outwardly from the guide-body and disengages the through openings so as to be able to receive, from the latter, said beverage through said inner chamber.
