<p>A dispensing package (1) for fluid products such as liquid soaps, shampoos and conditioners, household detergents, cleaners, polishes, moisturizing creams, and the like, includes a container (2) with a self-sealing dispensing valve (3) mounted therein. The valve (3) includes a marginal flange (4), a valve head (5) with a discharge orifice (6) therein, and a connector sleeve (7) having one end (5) connected with the valve flange (4) and the opposite end (49) connected with the valve head (5) adjacent a marginal edge (52) thereof. The connector sleeve (7) has a resiliently flexible construction, such that when pressure within the container rises above a predetermined amount, the valve head shifts outwardly in a manner which causes the connector sleeve to double over and extend rollingly a further increase in pressure causing the orifice to open. <IMAGE></p> |
