ABSTRACT:
A nozzle outlet in the stretchable, flexible wall for a container is provided by inner and outer sleeves mated together in wedging-locking relationship with a stretched portion of the wall material sandwiched between them. The inner sleeve has an outlet passage extending therethrough and has an exterior tapered surface which converges at a small angle toward one end, while the outer sleeve has an interior tapered surface which diverges at a small angle toward one end. The small angle of taper of this exterior and interior surface is the same, so that they will engage together in a wedging-locking relationship with a stretched portion of the wall material sandwiched, supported and protected between the wedgingly interlocked tapered surfaces, thereby firmly securing the nozzle outlet in place.
