A castor for pulverous, granular or lumpy substances such as spices is disclosed. The castor comprises a hollow body, a cap insert provided with an aperture and adapted to close off an opening in the body apart from the aperture in the cap insert. The cap insert rotatably supports a cover slide provided with a sieve plate having a plurality of differently apertured regions which - on rotation of the slide - can be selectably positioned over the aperture in the cap insert. The slide is provided with a sleeve structure connected to the sieve plate and having a plurality of sleeve elements each encompassing a respective one of the apertured regions in the sieve plate. Each sleeve element extends substantially perpendicularly from the side of the sieve plate remote from the cap insert to contact the underside of a lid on the latter being received by the castor.
