发明名称 METHOD FOR PRODUCING A RECLOSABLE SPOUT ELEMENT AND A CORRESPONDINGLY PRODUCED SPOUT ELEMENT
摘要 Represented and described are a method for the manufacture of a reclosable pouring element and a pouring element manufactured in accordance therewith, whereby the pouring element features a basic body (1) and a closure cover (2), and whereby the closure cover (2) is connected in jointed fashion to the basic body by means of two bearing pivots (4). In order to improve this method in its entirety, and to create a reliably tight connection between the basic body (1) and the closure cover (2) with the pouring element manufactured in this manner, the following steps are proposed: injection-moulding of the closure cover (2) from a first plastic; rotation of the mould about a predetermined angle and opening of at least a part of the mould of the closure cover (2); closure of a second mould for the basic body (1), the cavity of which is also formed at least in part from the closure cover (2); injection-moulding of the basic body (1) from a second plastic; and opening of the mould and removal of the finished pouring element.
