Device for closing containers,and container

摘要

The neck (1) and lid (3) of the container have locking devices (4,5) each formed underneath the screw thread in the direction of the container. The locking devices on the lid are rigid and those on the neck are deformable which is elastically reversible. The locking devices on the neck are longitudinally extended towards the container so that when the lid is fitted they project over same. The locking devices on the lid and neck can be formed from teeth with lips. The teething on the neck are inclined on one surface so that during fitting and turning the teething of the lid can pass unhindered over these inclined faces. USE/ADVANTAGE - Repeated opening and closing is possible without impairing the safety closing action.
