ABSTRACT:
A caster for pulverulent, granular or lumpy substances such as spices. The caster comprises a hollow body defining a storage chamber and at an outlet thereof is provided with a generally cylindrical wall portion defining a cavity of circular cross-section. Recess means are provided in the generally cylindrical wall portion to at least partially encompass the cavity. The caster includes a cap insert of synthetic material having a resilient portion latachably engaging the recess means to retain the cap insert on the body. A hollow cylindrical portion of the cap insert has an external diameter substantially equal to that of the cavity and is received in the cavity. A perforate plate portion of the cap insert extends across the interior of the hollow cylindrical portion and is perforate in at least one of a plurality of spatially differentiated regions of the plate portion. A cover slide is carried by the cap insert and is rotatably mounted in the interior of the hollow cylindrical portion thereof. A plate portion of the cover slide has an aperture therein and slidably contacts the perforate plate portion of the cap insert. A collar portion of the cover slide has wall members each extending substantially perpendicularly of the apertured plate portion to define therebetween a passage communicating with the aperture in the apertured plate portion. The caster includes a lid member which is adapted to be detachably mounted to the generally cylindrical wall portion of the hollow body to extend across the cavity. The lid member has an internal surface which, when the lid member is mounted on the body, is adapted to contact both the cap insert and end faces of the wall members remote from the apertured plate portion.
