Abstract
The present invention relates to a container for storing and discharging particulate material, in particular pulp chips. For the purpose of preventing bridge formation and making possible a simple and cost-effective design, the container is made so that a positive release is achieved in different transverse directions, after which the material is fed down towards the discharge end 2. The container 1 preferably has a rectangular cross section, with a number of container sections BS.sub.1 -BS.sub.8 in succession from the infeed end 4 of the container to its discharge end 2. Two opposite sides in each container section are given a diverging deflection (5.degree.) relative to the discharge end 2, and the other opposite sides in each container section are given a converging deflection (29.degree.). In following container sections, converging sides change to diverging sides and vice versa, which results in the positive release of the material being achieved alternately with a 90.degree. displacement.
