Pump trigger assembly for a trigger sprayer

An improved trigger sprayer apparatus is comprised of a venting system that allows air to enter a liquid container connected to the apparatus as the apparatus dispenses liquid from the container, a trigger member that provides reliable operation and prevents the inadvertent disconnection of the trigger member from the apparatus, a gasket connected to the apparatus between the liquid container and the apparatus, and a fluid conduit communicating with a nozzle orifice that centres a fluid spinner relative to the orifice.
