Abstract
An apparatus that can be inserted into the bottom end of liquid delivery tube for retaining fluid in the tube to aid in drinking, utilizing a ball valve that for the most part only allows unidirectional flow of fluid through the valve and into the tube to prevent the level of fluid in the tube from significantly dropping and also creates a fluid free space at the end of the tube to prevent spillage.
