Inventor: GONCALVES ANTONIN
IPC: B65D83/16
Filed: 1989-06-05
Abstract: A pressurised container (1) is provided with a dispensing head (5) comprising a peripheral skirt (6) for fastening to the container. The skirt is joined to a top (7) wherein there is formed a central movable strip between two parallel slots (20) (Fig. 3). This strip comprises a central portion in which is formed the sleeve for connection to the valve outlet tube (4) and which is joined, by two hinge zones (24) perpendicular to the above-mentioned slots, to two lateral zones carrying actuating levers (26) and being themselves joined to the fixed part of the top (7) by hinge zones (25) parallel to the hinge zones (24). The inward tilting of the lateral zones, by bringing the levers closer to each other, produces depression of the above- mentioned central zone, and of the tube (4) associated therewith, and as a result effects ejection of the product. The manipulation is simpler than with a conventional push button, particularly in the case where a dispensing end fitting (9) extends the connecting sleeve. <IMAGE>
