A dispensing closure system, a package including the same, a method of making the package on a form-fill-seal machine and a method of dispensing flowable products from the package are disclosed. The package includes an openable port in a wall in communication with the package's interior. The closure system comprises a fitment having a hollow body member, a resilient valve, and retainer assembly. The body member is secured to the package's wall and encircles the openable port. The valve is held in the body member by the retainer assembly, which comprises a retaining ring and a cap integrally connected to each other by a frangible connection. The cap includes a handle which may be pulled to break the frangible connection to remove the cap and thereby expose the valve for a dispensing probe to be extended therethrough to dispense the product.

The package of claim 8 wherein said openable port comprises a frangible portion of said wall of said package. 10. The package of claim 8 wherein said body member comprises a cylindrical sidewall and a peripheral flange, said peripheral flange being arranged to be fixedly secured to the wall of the package, whereupon said cylindrical sidewall encircles the openable port. 11. The package of claim 10 wherein said body member additionally comprises an internal ledge located within said cylindrical sidewall and arranged for supporting said resilient dispensing valve thereon over the openable port. 12. The package of claim 11 wherein said retaining member comprises a ring and wherein said retaining ring is arranged to engage an interior portion of said cylindrical sidewall to hold a portion of said resilient dispensing valve between it and said annular ledge with said cap being disposed over and covering said resilient valve. 13. The package of claim 8 wherein said retaining member and said cap are formed as an integrally molded member. 14. The package of claim 13 wherein said first portion of said cap comprises a ring-like handle. 15. The package of claim 14 wherein said ring-like handle projects upward from said cap. 16.
