US Patent 10196196 Watertight liquid dispenser with syringe-like functions

The present disclosure describes a capped syringe-like device for storing and dispensing liquid, with a movable plunger actuated by a rod inside a fluid dispensing container. The face sharing contact between the fluid dispensing container and the actuated plunger results in leak-proof dispensing of a controlled amount of liquid through a dispensing tip. The device may be used for refilling liquid containing vessels, for example.
