Claims11
A container assembly for use with a separate dispenser, comprising:
- a container initially filled with flowable particulate material;
- mounting means on the container at its discharge end adapted for detachably making said container coactive with structure on the dispenser;
- and a unitary diaphragm closure initially closing the discharge end of the container and having a rupturable circular line of weakness defining a prospective relatively axially displaceable body portion having the physical properties enabling it to be used in the dispenser to modulate an annular flow of the material through said discharge end.
