A portable container includes an outer component defining a hopper-like compartment having a bottom opening and an inner component having a stopper centered in the hopper with respect to the bottom opening and shiftable into and out of stoppering relation to the bottom opening, the outer compartment suspending the inner component into axially slid hopper-stoppering position and there being a target within the lower end of the inner component; and a discharge hopper positioned below the bottom opening and including a lance for penetrating through the bottom opening into contact with the target to axially lift the stopper to unstoppering position in response to lowering of the outer component relative to the discharge hopper. The outer compartment contains a granular product or a mixture of products and the inner component may also contain a compatible product. The dry products of concrete or mortar may thus be stored. The bottom opening of the inner compartment is covered with a diaphragm which is ruptured by the lance prior to engagement of the lance with the target so that the inner compartment is axially shifted relative to the outer compartment so as to effect unstoppering after the diaphragm is penetrated.
