<p>The spray head (5) is fixed to the flask by forcibly engaging a skirt (11) into the neck (3) until an annular shoulder (12) bears on the rim of the neck. A grooved end-piece (7) connects a plunger tube (8) to the spray head (5). The head (5) comprises a spray chamber (18) which communicates with the outside via the ejection orifice (14) and with the internal volume of the flask, on the one hand, via a bore (15) extended by the plunger tube (8) and, on the other hand, via the two grooves (17) of the end-piece. The head (5) includes an annular base (9) pierced by four large orifices (10) for taking up air, these being closed off by a valve consisting of a flexible washer (6). The orifices (10) are thus set back in relation to the ejection orifice, The atomizer, which operates regardless of its position, by compressing the walls of the flask, can be used, inter alia, in the cosmetics field. <IMAGE></p> |
