Resealable Spout for a Packaging, and a Mandrel of a Rotating Mandrel Wheel of a Packaging Machine to Mount said Spout, and a Combination of a Spout and a Mandrel

Abstract

The invention relates to a reclosable pour-out element for packaging, particularly composite packaging for liquid foodstuffs, with a main body having a pour-out tube closed off by a screw cap and a flange with polyhedral surfaces for connection to the outer side of packaging. The invention further relates to a corresponding mandrel of a rotatable mandrel wheel in a packaging machine. To enable reliable connection of the reclosable pour-out element on a mandrel and subsequently easy removal from the mandrel and also to achieve good possibilities for cleaning, according to the invention the pour-out element has a circumferential retaining element inside the main body or formfitting operative connection to a mandrel in a packaging machine. A corresponding mandrel has a polyhedral shape in the receiving region of the pour-out element and has a circumferential retaining element for form-fitting operative connection to the pour-out element.
