Abstract: A closure for the open mouth of an airtight container. The closure has a resiliently flexible diaphragm which has a peripheral edge (37) which can sealing engage against an inside wall surface of the open mouth. The diaphragm (13) is engaged with the second cover section (12) of a cover. A pair of toggles (24) are pivotally mounted on axles (22) of second cover section (12). The levers (30) of the toggles (24) extend through an opening (44) in the first or outer cover section (11) when the first and second cover sections (11,12) are snap-locked together. By moving the levers (30) toward one another the respective feet (27) of the toggle (24) engage with area (35) of the diaphragm (13) to deform the diaphragm and thereby break a sealing effect between the peripheral edge of the diaphragm and the inside wall surface of the open mouth.

Abstract: A grinder for grindable food materials such as salt and peppercorns. The grinder (10) has a body (11) which contains first and second grinder elements (15 and 17). The grinder elements have opposed grinding surfaces (16 and 18), between which grindable material can pass to be ground or milled when relative rotation therebetween occurs. This relative movement is caused by handle (13) driving shaft (14) connected to grinding element (15). An adjustment mechanism to adjust the distance between the grinding surfaces is included. The adjustment mechanism has a connector (30) which connects element (15) to the grinder body (22). Rotating the connector (30) by knob (35) causes the distance between the grinding surfaces (16 and 18) to be adjustably altered.
