Drinking straw for heated liquids, method of cooling and combination with drinking vessels

US-7537173-B1

Abstract

A drinking straw for delivering a hot liquid in the form of a foam into a user's mouth that mimics the natural action of sucking in air for cooling the liquid. The straw has a tube wall with an expanded portion proximate an outlet. Air admitting orifices are provided in the tube wall below the expanded portion so that air is drawn into the straw through the orifices when a liquid is sucked through the straw. The straw may be used for cooling a hot liquid such as coffee, tea, soup or the like and may be used in connection with a container.
