Abstract
A filter for squeezing or pressing out suspensions has the following main components: a boiler-shaped outer casing, a cover releasably closing the outer casing at its open end face, a tubular filter element projecting from the cover and an elastic membrane which is arranged between outer casing and filter element and is connected, on the one hand, to the open end face of the outer casing and, on the other, to the end face of the filter element remote from the cover such that the membrane is inverted when the cover is removed coaxially from the outer casing. In a filter of this type, the inner diameter of the slack membrane in the region of the filter element is equal to or smaller than the outer diameter of the filter element.
