Abstract
A tear-off tab structure applicable to a self-closing dispensing valve structure of the toggle type mounted on a spout in which passage to the outlet is normally-closed by an axially inwardly-extending flexible wall structure that can be flexed by a toggle lever carried thereby to complete a discharge passage to the outlet. The tear-off tab structure substantially covers the outlet and to give access to the spout through the outlet the tab structure must be disturbed thereby giving evidence of tampering.
