Abstract

A closet drier including a container having an upper portion and a lower portion divided by a normally stretched elastic diaphragm having perforations therein and retaining deliquescent material in the upper portion of the container, a membrane at the top of the container for permitting only water-vapor, but not liquid water, to pass therethrough into the deliquescent material which forms a solution with the deliquescent material which passes through the perforations into the lower portion of the container, the elastic diaphragm contracting as the deliquescent material is consumed so that the space previously occupied by the deliquescent material can be occupied by the resulting solution, and the perforations in the elastic diaphragm also contracting as the elastic diaphragm contracts to reduce the ability of liquid from underneath the diaphragm in the container from passing therethrough.
