Abstract

A coffee and/or tea disperser having a cold water reservoir connected to a water heater which is connected in turn to a spray head. Below the head is a container for a bed of coffee grains or tea leaves and below which again is a tank for the infused beverage. Cups of freshly infused coffee or tea can be metered from the tank by a dispensing valve. In order to ensure that the amount of coffee dispensed does not vary by any significant amount as the head of liquid in the tank varies, the tank is disposed above the surface on which the cup rests by a distance, measured from the maximum head of liquid in the tank to said datum, which is at least six times the maximum displacement of liquid in the tank. Moreover the tank is wide and low. The tank is preferably dismountable for easy cleaning and level probes normally protruding into the tank are arranged to be swung out of the tank to assist dismounting. The dispensing valve is preferably formed with a flexible liquid conduit squeezed between three abutments so that the tube is not clamped but rather distorted into a closed state.
