A fluid dispensing closure includes a closure base having a deck, a skirt for securement to a container finish and a recess in the deck. The recess includes a first annular wall extending from the deck within the skirt, a second annular wall extending radially inwardly from the first annular wall at a position spaced from the deck, and a third annular wall extending toward the deck from an inner periphery of the second annular wall. A dispensing valve of flexible resilient elastomeric construction has a peripheral portion captured in compression between a collar and the third annular wall, and a concave central portion with at least one dispensing slit. In the preferred embodiment, the collar includes a flat annular deck, and a first annular wall extending from an outer periphery of the flat annular deck and engaging the third annular wall on the base to secure the collar and the valve to the base such that the outer surface of the annular deck of the collar is flush with the outer surface of the deck of the closure base.

The invention claimed is: 1. A dispensing closure for fluid products, which includes: a closure base having a deck, a skirt for securement to a container finish, and a recess in said deck including a first annular wall extending from said deck within said skirt, a second annular wall extending radially inwardly from said first annular wall at a position spaced from said deck, a third annular wall extending toward said deck from an inner periphery of said second annular wall, and a lid integrally hinged to said base to pivot between a closed position overlying said deck and an open position spaced from said deck, a collar secured to a free end of said third annular wall, and a dispensing valve of flexible resilient elastomeric construction having a peripheral portion captured in compression between said collar and said third annular wall, and a central portion with at least one dispensing slit, said collar including a flat annular deck, a first annular wall extending from an outer periphery of said flat annular deck and engaging said third annular wall on said base to secure said collar and said valve to said base, said collar including a second annular wall extending from an inner periphery of said flat annular deck, and said lid includes a wall for engaging said second annular wall on said collar to hold said lid in said closed position. 2. The closure set forth in claim 1 wherein an outer surface of said annular deck of said collar is flush with an outer surface of said deck of said closure base. 3. The closure set forth in claim 1 wherein said first annular wall on said collar and said third annular wall on said base have interlocking snap beads to secure said collar and said valve to said base. 4. The closure set forth in claim 1 wherein said second annular wall on said collar and said wall on said lid include snap beads for holding said lid in said closed position. 5. The closure set forth in claim 2 wherein said outer surfaces are in a plane that is at an angle to an axis of said skirt. 6. A fluid dispensing package that includes a container having a finish and a dispensing closure secured to said finish, said closure including: a closure base having a deck, a skirt for securement to a container finish, and a recess in said deck including a first annular wall extending from said deck within said skirt, a second annular wall extending radially inwardly from said first annular wall at a position spaced from said deck, a third annular wall extending toward said deck from an inner periphery of said second annular wall, and a lid integrally hinged to said base to pivot between a closed position overlying said deck and an open position spaced from said deck, a collar secured to a free end of said third annular wall, and a dispensing valve of flexible resilient elastomeric construction having a peripheral portion captured in compression between said collar and said third annular wall, and a central portion with at least one dispensing slit, said collar including a flat annular deck, a first annular wall extending from an outer periphery of said flat annular deck and engaging said third annular wall on said base to secure said collar and said valve to said base, said collar including a second annular wall extending from an inner periphery of said flat annular deck, and said lid includes a wall for engaging said second annular wall on said collar to hold said lid in said closed position. 7. The package set forth in claim 6 wherein an outer surface of said annular deck of said collar is flush with an outer surface of said deck of said closure base. 8. The package set forth in claim 6 wherein said first annular wall on said collar and said third annular wall on said base have interlocking snap beads to secure said collar and said valve to said base. 9. The package set forth in claim 6 wherein said second annular wall on said collar and said wall on said lid include snap beads for holding said lid in said closed position. 10. The package set forth in claim 7 wherein said outer surfaces are in a plane that is at an angle to an axis of said skirt.
