The closure of claim 6 wherein the second flap includes a snap lock mechanism for securing the second flap in its closed position overlaying the first flap and the outer surface of the end wall and between the two abutments. 8. The closure of claim 1 wherein the second flap includes a snap lock mechanism for securing the second flap in its closed position overlaying the first flap and the outer surface of the end wall. 9. The closure of claim 1 wherein the container has a threaded neck, and wherein the skirt includes threads configured for being threaded onto the threaded neck of the container. 10. The closure of claim 1 wherein the first flap has side edges configured to engage edges of the opening when the first flap is positioned within the opening, and wherein the upper surface of the first flap is substantially coplanar with the substantially planar outer surface of the end wall when the first flap is in the first state. 11. The closure of claim 1, further comprising a snap lock mechanism for retaining the second flap in a closed position wherein the snap lock mechanism includes the outer surface of the end wall having a shoulder integrally formed about a top peripheral portion and the second flap having a downwardly protruding skirt about the substantially semicircular outer edge of the second flap, the second flap skirt configured to selectively engage with the shoulder of the end wall. 12. The closure of claim 11 wherein the skirt of the second flap includes an internal beveled edge for engaging an outer edge of the shoulder of the end wall. 13. The closure of claim 1 wherein the second flap includes an inner surface with one or more bosses, each boss being configured to be received within a respective one of the first flap apertures for closing the apertures when the second flap overlays the first flap. 14. The closure of claim 1 wherein the opening in the end wall is dimensioned to include a half circle portion configured to accept a spoon for extracting product held by the container. 15. A dispensing cap for a container having a round mouth at an end of the container comprising: a monolithic cylindrical body having a downwardly depending skirt for sealable connection to the mouth of the container and end wall, a first flap with a first hinge and a second flap with a second hinge; the end wall at the upper end of the skirt for closing the mouth of the container when the closure is mounted to the container, the end wall having an opening for dispensing a product held by the container, the end wall having a substantially planar outer surface and a pair of opposing abutments extending upward from the outer surface of the end wall and from opposing portions of the skirt and having an top abutment surface and defining to outwardly angled straight inner edges; the first flap having a plurality of small apertures, the first flap being hingedly attached with a first hinge to the end wall proximate to the opening and adapted for selective rotational movement in a first orientation between a closed position in which the first flap seals the opening and an opened position in which the first flap is free from the opening for enabling the product held by the container to pass through the opening; and the second flap hingedly connected with a second hinge to the body for selective rotational movement in a second orientation between a closed position in which the second flap overlies the first hap and the substantially planar surface of the end wall and between the two outwardly angled straight inner edges of the abutments and seals the small apertures in the first flap and an opened position in which the second flap is free of the first flap, the planar surface of the end wall and the two inner edges of the abutments and unseals the small apertures in the first flap for enabling the passing of the product through the small apertures, the second orientation being the same as the first orientation. 16. The dispensing cap of claim 15 wherein the second flap includes an inner surface with bosses, each boss being configured to be received within one of the small apertures for closing the apertures when the second flap is in its closed position. 17.
