A dispenser assembly that can be used as a dispenser on a container includes a dispenser body having a flow passage, and a porous flow control member positioned in the flow passage such that the liquid must pass through at least a portion of the porous flow control member before being dispensed. The porous flow control member is operable to vary a resistance to flow of the liquid through the dispenser assembly during dispensing. A valve is provided and is movable between an open position that allows the liquid to be dispensed and a closed position that prevents the liquid from being dispensed. A discharge spout directs the flow of liquid discharged from the container. A dip tube is attached to the dispenser body and extends inside the container to supply the liquid to be discharged to the dispenser body. An attachment portion is provided to attach the dispenser assembly to the container.

We claim: 1. A dispenser assembly for dispensing a liquid from a container, said dispenser assembly comprising: a dispenser body defining a flow passage; and a porous flow control member having a length and positioned in the flow passage such that at least some of the liquid must pass through at least a portion of said porous flow control member before being dispensed, wherein said porous flow control member has varying porosity over its length and is movable relative to the flow passage to vary a length of said porous flow control member that the liquid must pass through before being dispensed, in order to vary the resistance to the flow of the liquid and to vary the porosity of the portion of said porous flow control member through which the liquid must pass before being dispensed. 2. A dispenser assembly as set forth in claim 1, further comprising a valve, movable between an open position that allows the liquid to be dispensed and a closed position that prevents the liquid from being dispensed. 3. A dispenser assembly as set forth in claim 1, further comprising: a discharge spout that directs the flow of discharged liquid; and a dip tube attached to said dispenser body and extending inside the container to supply the liquid to said dispenser body to be discharged. 4. A dispenser assembly as set forth in claim 1, further comprising an attachment portion for attaching said dispenser assembly to the container. 5. A dispenser assembly as set forth in claim 4, wherein said dispenser body is formed integrally with the container. 6. A dispenser assembly as set forth in claim 1, wherein said porous flow control member comprises a piece of rigid material. 7. A dispenser assembly for dispensing a liquid from a container, said dispenser assembly comprising: a dispenser body defining a plurality of flow passages; and a plurality of porous flow control members, wherein each of the flow passage has one of the plurality of porous flow control members disposed therein such that at least some of the liquid must pass through at least a portion of one of the porous flow control members before being dispensed, wherein said dispenser assembly is operable to vary a resistance to flow of the liquid through said dispenser assembly by adjusting usage of the plurality of flow passages, and wherein each of said plurality of porous flow control members has a different length, such that the resistance to flow of the liquid can be varied by selecting which of said plurality of flow passages the liquid is allowed to flow through during dispensing. 8. The dispenser assembly as set forth in claim 7, wherein the number of the plurality of flow passages, through which the liquid flows during dispensing is selectable, in order to vary the resistance to the flow of the liquid. 9. A dispenser assembly as set forth in claim 1, wherein the area of said porous flow control member through which the liquid is allowed to flow during dispensing is variable in order to vary the resistance to flow of the liquid through the flow passage. 10. A dispenser assembly as set forth in claim 1, wherein said porous flow control member is made of a porous material selected from the group consisting of ceramics, metals, glass structures, plastics, organic structures, polymers, and composites thereof. 11. A dispenser assembly as set forth in claim 1, wherein said porous now control member is made of a material selected from the group consisting of sintered materials, granular materials, fibrous materials, and foamed materials. 12. A dispenser assembly as set forth in claim 1, wherein said porous flow control member comprises a plurality of glass beads. 13. A dispenser assembly as set forth in claim 1, wherein the liquid to be dispensed is a carbonated beverage. 14. A dispenser assembly for dispensing a liquid from a container, said dispenser assembly comprising: a dispenser body defining a flow passage; and a porous flow control member having a length and positioned in the flow passage such that at least some of the liquid must pass through at least a portion of said porous flow control member before being dispensed, wherein said porous flow control member is configured to provide a varying resistance to the flow of liquid along it length and is movable relative to the flow passage, such that movement of the porous flow control member varies a length of the portion of said porous flow control member through which the liquid must pass before being dispensed; a valve, movable between an open position that allows the liquid to be dispensed and a closed position that prevents the liquid from being dispensed; a discharge spout that directs the flow of discharged liquid; a dip tube attached to said dispenser body and extending inside the container to supply the liquid to be discharged to said dispenser body; and an attachment portion for attaching said dispenser assembly to the container. 15. An assembly for dispensing a carbonated beverage, comprising: a container for containing a carbonated beverage; a dispenser body defining a flow passage and attached to said container by an attachment portion; a porous flow control member positioned in the flow passage such that at least some of the beverage must pass through at least a portion of said porous flow control member before being dispensed; a valve, movable between an open position that allows the beverage to be dispensed and a closed position that prevents the beverage from being dispensed; and a dip tube attached to said dispenser body and extending inside the container to supply the beverage to said dispenser body to be discharged, wherein said porous flow control member has varying porosity over its length and is movable relative to the flow passage, such that moving the porous flow control member within the flow passage varies a length and the porosity of the portion of said porous flow control member through which the liquid must pass before being dispensed in order to vary the resistance to flow of the liquid through the flow passage during dispensing.
