ABSTRACT:
By employing two independent, separate and distinct flow paths which are controllably sequentially opened during use in a single actuation operation, an error-free, spill-free flame and explosion proof liquid delivery/filling system is achieved. In the preferred embodiment, both flow paths are normally maintained in a closed, sealed configuration, requiring an actuation force to controllably, sequentially open the flow paths. In addition, by providing a cooperating, mating liquid transfer assembly, the container on which the liquid delivery/filling system is mounted can be refilled with safety and ease, completely eliminating spillage of the liquid. In this way, a fully integrated, cooperating, liquid flow controlling system is realized. Furthermore, a process for distributing toxic chemicals is disclosed which provides full control over the chemicals being distributed and prevents unwanted spillages, misuse, and mishandling of the chemicals in an unpressurized, gravity fed system.
