A safety system intended for electrically operated kitchen appliances, such as blenders and food processors comprises a clutch that selectively couples and decouples the drive between a motor and an implement rotatable about an axis within a container. The clutch reciprocates between a first decoupling position and a second coupling position and is configured to require the application of a force in excess of 20 newtons for movement to the second coupling position against a resilient means. The pressure may be exerted via the lower rim of the side wall of a bottomless goblet. The clutch may comprise a plurality of spring members (44, 45, 46) symetrically distributed about the axis, an annular spring cover (50) having recesses for symetrically distributed screw pillars (21, 22, 23). |
