ABSTRACT:
The actuating device (1) is adapted to be incorporated into a dispenser provided with a valve (41) having a tubular end (43) which must be pressed in order to discharge the product. The device (1) includes a poppet valve (10), the movement of which is substantially transverse to the axis of the end (43). Action by the user on the push-button results, on the one hand, in opening of the poppet valve (10) and, on the other hand, in pressure being exerted on the tubular end (43) by the use of a film hinge (39). The vertical movement of the push-button is converted into a horizontal movement of the popper valve by means of an orthogonal joint. The product to be dispensed still pass into a chamber rendered airtight by the poppet valve (10) and a flexible collar (13), so that the product, especially a self-foaming product, remains hermetically sealed in the chamber during periods of non-use.
