摘要：A dispensing package (1) for fluid products such as liquid soaps, shampoos andconditioners, 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 aconnector sleeve (7) having one end (50) connected with the valve flange (4) and theopposite 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 whenpressure within the container rises above a predetermined amount, the valve head shiftsoutwardly in a manner which causes the connector sleeve to double over and extendrollingly a further increase in pressure causing the orifice to open. The valve has a headportion (15) of generally tapered construction which is relatively thicker at a radiallyouter portion of the head and relatively thinner at a radially inner portion. The valve headis generally outwardly concave in a rest position thereof and the connector sleeveenables the valve head to move outwardly from and rearwardly to the rest position inresponse to changes in pressure, the orifice remaining closed while the pressure remainsless than the predetermined amount. The connector sleeve, in the rest position, isgenerally J-shaped in longitudinal section.
