摘要： Apparatus for storing and dispensing particulate material comprising a container defining a chamber for storing particulate material having an opening in the surface for dispensing particulate material which may be closed and sealed. The opening has a frame member attached to the container enclosing the opening which has two spaced parallel rails one each on a side of the opening and a movable door member larger than the opening with two parallel tracks spaced to enable them to slide in the rails to move said door between a closed position to cover the opening and an open position to open the door and between the door frame member and the door a compressible micro-cellular open celled foam seal having a low compression set, a low surface energy surface and a thickness in the uncompressed state greater than the distance between the door frame and the door when the door is in the closd position the foam being compressed on sealing the space between the door frame and the door when the door is in the closed position to prevent particulate material from escaping from the container.
