Abstract
An infuser which is primarily intended for use in making coffee can be constructed utilizing a container having a bottom inlet. A filter element is located within the interior of the container in such a manner that the position of the filter element relative to the bottom of the container can be adjusted. The outlet for the container comprises a tube slidably mounted in the bottom of the container and spring biased upwardly so that the upper end of the tube is in communication with an opening through the filter at all times that the filter is in place within the interior of the container. The container preferably includes a lid which seals off the interior of the container and which carries a threaded shaft and a nut type structure for linearly moving the shaft. The shaft is secured to the filter so that as the nut is rotated the position of the filter within the container can be varied.
