Abstract

A plastics weld pourer component having child-proof properties for attachment by welding to a container component of film-like plastics material, includes a tubular body portion defining a through passage having axially spaced ends. A plurality of welding ribs is formed integrally on the outer periphery of the body portion near one axial end of the through passage. Furthermore, a cap member is integrally formed on the body portion near the other axial end, said cap member sealing the through passage at one end. The cap member is attached to the body portion through a weakened portion which is adapted to break when a rotational force is exerted by hand on the cap member. The dimensions of the cap member relative to those of the body portion are made such that the cap member can be placed on the body portion for repeatedly sealing the through passage after it has been separated from the body portion. Furthermore, the cap member is also permanently attached in one-piece manner to the body portion through a meandering strap. A radially spaced ring element integrally formed with the cap member provides a flow passage between the cap member and the ring element, said flow passage acting as an emergency breathing passage should the cap member be accidentally swallowed.
