Trigger sprayer for upright or inverted dispensing without leakage
摘要:
This invention relates to a trigger sprayer dispenser which can be used to dispense liquids in multidirections. The present invention incorporates a mechanism in a conventional trigger sprayer to allow the sprayer to be used in an inverted position without the dispenser contents leaking through a sprayer vent orifice. The mechanism comprises a by pass chamber in communication with the chamber of the dip tube. The by pass chamber then creates an auxiliary fluid path to the dip tube fluid path when the dispenser is inverted. When the dispenser is inverted, the fluid remaining in the dip tube acts as a fluid lock thereby preventing internal dispenser air from escaping out from the dip tube into the trigger sprayer. The by pass mechanism therefore, also allows for more efficient evacuation of the dispenser contents.
