POUR OPENING MEMBER FOR PACKAGING BAG

WIPO Patent Application WO/2010/004746

A1

In the past, with packaging bags wherein an inside stopper in a pour opening is opened to open the pour member in the packaging bag, the problem is that the pour opening is touched by the hand to open. With packaging bags that are opened by turning a cap, the problem is that the cap may turn during transport and the plug may come out. With packaging bags wherein a twist-off projection at the tip of the pour opening is protected with a squared U shaped guard member, the problems are that the pour opening is exposed and production is cumbersome. Disclosed is a pour opening member for a packaging bag wherein the pour opening member (10) comprises a base (1) attached to a packaging bag, a tube (4), the tip (2) of which is sealed by a seal member (3), and a lid member (20), the top end of which is joined to the seal member (3), and that covers the outer circumference of the tube (4). A separable release piece (6), the top end of which is joined to the seal member (3), is provided on the lid member (20) to allow opening, while a rotation locking mechanism (30) that hinders separation and release of the separable release piece (6) of the lid member (20) and that can be separated and released is provided between the separable release piece (6) and the tube (4).
