Apparatus include a liquid container body defining a reservoir and having a vent aperture defined therethrough, and a quantity of expandable foam disposed within the aperture. The cured expandable foam can act as a vent plug to prevent liquid from leaking out of the container body through the aperture, while also allowing air or other such gases to pass through the aperture for venting of the reservoir. Methods include steps of installing a plug into a vent aperture defined through a liquid container body. The steps can consist of dispensing a quantity of expandable foam into the vent aperture.
