Abstract

The invention relates to a discharge apparatus for a funnel-shaped container 1 with an outlet 3 at its narrower end. The object is to provide an even discharge of a powder material highly susceptible to bridging, until the container is empty. This is achieved by positioning, on the inside of the container wall 2, elements 4 made of a gas-permeable material and extending towards the outlet 3, whereby each channel defined between the elements 4 and the container wall 2 is divided into separate transverse sections 9 each provided with a throttled supply of gas. The gas, which penetrates the elements 4, activates the powder so that an even outflow is achieved. Due to the throttled supply of gas, the even flow continues until the container 1 is empty. <IMAGE>
