Abstract

A dispensing package for fluid products includes a container having a body for holding a product to be dispensed and a finish having an open mouth. A closure base includes a ledge with a skirt externally secured to the container finish and a wall extending from the ledge coaxially with the container mouth. A collar has a deck with a central opening aligned with the mouth, and a wall secured to the wall on the closure base. A lid is integrally connected to the collar or the base by at least one hinge. A dispensing valve of flexible resilient elastomeric construction has a peripheral portion captured between the collar deck and the base wall for securing the valve in position and simultaneously functioning as a seal between the base and the collar. An intermediate portion of the valve is in facing engagement with the collar deck, and an annular wall portion of the valve extends from the inner end of the intermediate portion. An inner portion of the valve extends radially inwardly from the annular wall portion and has at least one dispensing slit for dispensing product from the container.
