A toilet bowl rim block dispenser comprises a body (1) for receiving a block of material (14) to be dispensed, and a hook (2) by which the dispenser may be attached to the rim of a toilet bowl. The body (1) is provided with apertures (3) by which water may enter or leave the body (1) when the toilet is flushed. The body comprises a thermoplastic moulding, having a first part which comprises the hook (2) and a first body part (4) which is linked to a second body part (5) by a hinge (6) moulded into the body. Body part (4) carries a single projecting lug terminating in a barb (7). When the first and second body parts are brought together by rotation about hinge (6), the lug and barb (7) engage an aperture (8) in the second body part (5). The body is opened by manually depressing barb (7) so as to disengage it from aperture (8), which is normally prevented by locking means (9), connected to body part (5) by pairs of ribs (10, 11). When no block (14) is present in the dispenser, pressing the lower end (13) of the locking means (9) causes it to move inward, while the upper end (12) moves outward relative to the dispenser, so that downward movement of the barb (7) is no longer restrained, and the barb may be depressed, permitting opening of the body. When a block (14) is present in the dispenser, pressing the lower end (13) of the locking means (9) is inhibited by the presence of the block, and the body may not be opened. |
