A fluid dispensing system includes a base for attachment to an associated pouch and a neck extending outwardly therefrom away from the pouch. The neck and base include a bore formed therethrough in fluid communication with the pouch interior. The neck comprises first and second portions, and the bore is closed at its outermost end by the second neck portion. The second portion is selectively removable from the first portion to open the bore and provide access to the contents of the pouch. The second portion can be at least partially separated from the first portion by selective application of bending or torsional stress or the like thereto. The application of stress results in partial or complete disconnection of the second portion from the first portion along a weakened material zone. The weakened material zone is defined by an area of reduced material thickness or by scoring or the like. A normally closed valve is optionally employed as a part of the fitment and is adapted for preventing undesired spillage of liquid from the associated pouch. The valve is constructed from a resilient material such as rubber or other flexible polymer, and the application of manual pressure to one or more regions of the valve opens a fluid passage formed therethrough. The neck is optionally enclosed by a removable sanitary overwrap to prevent undesired contamination of the fitment neck during shipping and storage.

[ Having thus described the preferred embodiments, the invention is now claimed to be:] [10.]10. A fluid dispensing system comprising:a fluid container defining an internal cavity adapted for retaining fluid;a fitment connected to said container and adapted for dispensing fluid from said container, said fitment comprising:(i) a base adapted for securement to said container;(ii) a neck first portion extending outwardly from said base away from said container, said neck first portion and base including a bore therein in fluid communication with said internal cavity of said container; and,(iii) a neck second portion removably connected to said neck first portion in fluid-blocking relation with said bore by a weakened material zone, said neck second portion adapted for at least partial separation from said neck first portion upon application of stress to said neck second portion to thereby rupture said weakened material zone and open said bore; and,a normally closed valve connected to said fitment and located in said internal cavity of said fluid container, said valve, when closed, substantially blocking fluid flow out of said container internal cavity through said bore, said valve selectively openable to allow fluid flow out of said container internal cavity through said bore when said neck second portion is at least partially separated from said first neck portion.
