<p>A squeeze-type container package (20) that comprises a flexible resilient container body (22) and a self-sealing closure assembly (30) mounted to the mouth of the container body. The self-sealing closure assembly includes a dispensing valve (36) of one-piece integrally molded elastic construction having an annular base (64), an internal wall portion (72) that extends radially inwardly and axially from the base, and a mouth portion that includes a slit opening (76) oriented diametrically of the annular base. Internal stresses within the wall portion bias the slit to the closed position. An annular lip (68) that extends radially outwardly from the valve cooperates with an annular internal rib (84) on the closure for venting the interior of the container body to atmosphere when the container body is released following dispensing of product. <IMAGE></p> |
