ABSTRACT:
A liquid dispensing assembly and method of construction for a push-pull type valve having a sealing mechanism which resists undesirable dislodgement or leakage such as encountered during transport. The push-pull valve for a container or bottle is equipped with a security seal or connection plug formed between the inner stem and the outer sleeve which preventing any relative movement between the inner and the outer sleeve during transport, is easily fracturable through deliberate actuation by the user rotating the inner stem.
