Infuser
A perforated, ball-shaped or basketlike container with a hinged opening, most often used to hold loose tea when brewing tea. A tiny chain with a hook at one end is attached to the top of the infuser; the hook slips over the rim of the teapot so the infuser can easily be retrieved after the tea has steeped. The round hinged balls are also called “tea balls.”
