Abstract
A push/pull type dispenser closure is provided by the present invention. The closure includes a cap body, slider valve and an overcap. The closure may be placed in the closed and sealed position by attaching the overcap to the cap body. The overcap includes an annular ring that engages the slider valve when the overcap is placed on the cap body, so as to ensure that the slider valve is forced into the closed and sealed position. The slider valve includes an annular seal with increased flexibility that provides for a more facile closing and sealing of the closure
