A fluid container is disclosed. The container includes an enclosure for containing liquid and a first closure member. The first closure member is in the form of a fluid discharge assembly which includes a selectively removable valve body mounted for movement between an open position to permit flow of liquid from the enclosure and a closed position to prevent flow of liquid through the fluid discharge assembly. In addition, the closure includes a cap member mountable to a container, and the cap member defines a product outlet passage. The valve body is disposed for movement within the outlet passage between an open position to permit flow of product through the passage from said container and a closed position to prevent flow of product through the passage. The valve body is selectively removable from the outlet passage.

1. A removable valve body for manually opening and closing a product exit duct communicating with the interior of a fluid container, said valve body comprising: a unitary body disposed for longitudinal movement within said duct between an open position to permit flow of fluid through said duct and unitary body from said container and a closed position to prevent flow of fluid through said duct and unitary body, said unitary body being constructed from elastic material to permit selective deformation and removal thereof from said exit duct when said unitary body is deformed and rotated relative to said duct,wherein said unitary body comprises a valve sleeve sized and shaped for positioning within said duct, said valve sleeve having an open first end adapted for positioning within said duct and a substantially closed second end adapted for positioning exterior to said duct, said second end having a central aperture therein for communicating with the interior of the container,wherein said valve sleeve further includes at least one stop member in the form of an ear projecting radially outwardly from the outer surface thereof and adapted to limit the longitudinal movement of said valve body within said duct between said open and closed positions, andwherein each said ear includes a radially disposed outer edge, a pair of upper and lower shoulders defined by said outer edge for limiting the longitudinal movement of said stop member within said duct, a pair of end shoulders for limiting rotational movement of said stop member within said duct, and a chamfered surface extending from one said end shoulder to said outer edge to form a wedge adapted for engagement against said duct in response to selective rotational force imposed on an end cap when said valve body is in its open position to assist in deforming said unitary body radially inwardly. 2. The valve body of claim 1, wherein said second end includes a valve cap sized and shaped for closing the second end of said duct when said valve body is in a closed position. 3. The valve body of claim 2, wherein said valve sleeve includes at least one integrally molded O-ring disposed about the outer surface thereof 4. A valve assembly for manually opening and closing a fluid container discharge opening and adapted for disassembly for cleaning purposes, said valve assembly comprising: (a) a fluid discharge sleeve enclosing said discharge opening and extending longitudinally with respect thereto, said discharge sleeve having an outer end opening and an inner end opening;(b) a shaft extending longitudinally along a central axis of said discharge sleeve, said shaft having a distal end portion proximate the outer end opening of said discharge sleeve; and(c) a detachable valve body disposed for movement along said shaft within said discharge sleeve between an open valve position to permit flow of fluid product through said discharge opening from said container and a closed valve position to prevent flow of product through said discharge opening, said valve body being selectively removable from said discharge sleeve when said detachable valve body is rotated relative to said discharge,wherein said valve assembly includes stop members disposed between said discharge sleeve and said valve body to limit the longitudinal movement of said valve body within said discharge sleeve and to selectively restrict rotational movement of said valve body within said discharge sleeve, said stop members comprising at least one stop member disposed on the outer surface of said valve body and at least one slot defined in said discharge sleeve, each said stop member being seated within one said slot with the length of said slot defining the longitudinal movement of said valve body within said discharge sleeve between said open and closed positions, andwherein said valve body is constructed from elastic material, and wherein each said stop member projects radially outwardly from said elastic valve body and includes a surface adapted for engaging said collar in response to selective rotational force imposed on said valve body in its open position to radially compress and deform said valve body for selective detachment from said discharge sleeve. 5. The valve assembly of claim 4, wherein said valve body is constructed from elastic material arid is radially deformable for selective detachment from said discharge sleeve. 6. The valve assembly of claim 5, wherein said valve body includes a central cavity sized and shaped for mounting along said shaft and a closed outer end portion disposed exterior to said discharge sleeve outer end opening and having a central aperture defined therein, said central aperture being sized and shaped to engage said shaft distal end portion when said valve body is in said closed position. 7. The valve assembly of claim 6, wherein the central aperture of said outer end includes an annular lip member extending inwardly into said central cavity to provide a sealing surface with said shaft distal end portion when said valve body is in said closed position. 8. In a pop-up valve assembly for manually opening and closing a fluid container including a product exit port and a valve body longitudinally movable relative to said port between an extended open position for fluid discharge and a depressed closed position for fluid containment, the improvement wherein said valve body is constrained for movement between the open and closed positions yet which includes means for selectively disengaging and removing said valve body from said port when said valve body is rotated relative to said port, wherein said means comprises said valve body being constructed from elastic material and being radially deformable for selective detachment from said port wherein said product exit port is substantially tubular in form having an outer end opening and an inner end opening and includes a shaft extending axially along the centerline thereof, said shaft having a distal end portion proximate the outer end opening of said port, and wherein said valve body includes a central cavity adapted for axial movement along said shaft within said port and a closed outer end portion having a central aperture defined therein, said central aperture being sized and shaped to engage said shaft distal end portion when said valve body is in said closed position and disengage said shaft distal end portion when said valve body is in said open position, andwherein said valve body includes at least one stop member projecting radially outwardly therefrom, wherein said tubular port includes guide members for defining at least one longitudinal slot within said port, each said stop member being seated within one said slot to both limit the longitudinal movement and restrict rotational movement of said valve body within said sleeve, and wherein each said stop includes a surface adapted for engaging a guide member in response to selective rotational force imposed on said valve body in its open position to radially compress and deform said valve body for selective detachment from said discharge sleeve. 9. The improvement of claim 8, wherein said shaft includes support elements disposed between said shaft and said valve body aligned proximate said slots to prevent the axial removal of said deformable valve body from said exit port while said stop members are positioned within said slots. 10. The improvement of claim 8, wherein said fluid container includes a removable top portion which contains said pop-up valve assembly, and wherein said top portion, said exit port, said shaft and said support elements comprise one integral unit.
