• a lid integrally connected to said collar or said base by spaced hinges for pivoting between positions overlying and spaced from said first cylindrical wall, and a cylindrical wall with an internal bead on said lid for receipt over said first cylindrical wall and said external bead on said collar, and
• a dispensing valve of flexible resilient elastomeric construction, said dispensing valve having a peripheral portion captured in compression between said collar deck and said base cylindrical wall for securing said valve in position and simultaneously functioning as a seal between said base and said collar, an intermediate portion underlying said collar deck, an annular wall portion extending from an inner end of said intermediate portion radially inwardly adjacent to an inner surface of said first cylindrical collar wall, an inwardly concave inner portion extending radially inwardly from said annular wall portion, and at least one dispensing slit in said inner portion.

A dispensing closure assembly for fluid products, which comprises:

• a closure base including a ledge with a skirt for external securement to a container finish and a cylindrical wall extending from said ledge,
• a collar having a deck with a central opening, a first cylindrical wall surrounding said opening, and a second cylindrical wall externally surrounding and secured to said cylindrical wall on said base,
• a lid integrally connected by at least one hinge to said collar or said base, and
• a dispensing valve of flexible resilient elastomeric construction, said dispensing valve having a peripheral portion captured in compression between said collar deck and said base cylindrical wall for securing said valve in position and simultaneously functioning as a seal between said base and said collar, an intermediate portion underlying said collar deck, an annular wall portion extending from an inner end of said intermediate portion radially inwardly adjacent to an inner surface of said first cylindrical collar wall, an inwardly concave inner portion extending radially inwardly from said annular wall portion, and at least one dispensing slit in said inner portion.

A method of making a dispensing closure assembly for fluid products, which comprises the steps of:

• (a) providing a closure base of molded plastic construction that includes a ledge with a skirt for external securement to a container finish, a cylindrical wall extending from said ledge and a bead around said cylindrical wall,
• (b) placing against an end of said cylindrical wall a dispensing valve of flexible resilient elastomeric construction having a peripheral portion engaged with an end of said cylindrical wall, an intermediate portion, an annular wall portion extending from an inner end of said intermediate portion, a concave inner portion extending radially inwardly from said annular wall portion, and at least one dispensing slit in said inner portion,
• (c) securing a collar to said cylindrical wall of said closure base, said collar having a deck opposed to and engaged with said peripheral and intermediate portions of said valve such that said peripheral portion of said valve functions as a seal between said base and said collar, and a bead secured over said bead on said cylindrical wall of said base, and
• (d) integrally connecting a lid to said collar or said base by spaced hinges for pivoting between positions overlying and spaced from said first valve.

A dispensing package for fluid products, which comprises:

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