A dispensing cap for a product container, preferably a cosmetic product container, is provided. The cap includes a movable member comprising a valving portion capable of selectively opening and closing a product-dispensing orifice depending upon pressure within the container. The cap also includes an elastically deformable mounting element coupled to the movable member to retain the movable member on the cap, and the mounting element comprises a sealing member configured to selectively open and close at least one air intake passage, the air intake passage being separate from the product-dispensing orifice.
