ADHESIVELY APPLYING OPENABLE SEAL TO OPENING IN PLASTICS CONTAINER

摘要

A method and apparatus for sealingly closing a pack for liquids in which the top of the pack is provided with a hole into which is fitted a pouring device that includes a cup-like recess which defines a flange. The apparatus includes a pivot device that pivots about a main horizontal axis. The pivot device includes several mandrels onto which the pouring devices are to be individually mounted. The mandrels are rotatable about their respective longitudinal axes to allow a thread of adhesive to be applied to the flange of each pouring device so that the pouring device can be subsequently attached to the top of the pack by joining the flange of the pouring device to the collar of the hole in the pack.
