What is claimed is: 1. A slide tap comprising: a body defining a channel including a first open end and an outlet port from which fluid is dispensed; an actuator slidable within said channel, said actuator being a cylindrical shape with a closed end thereof configured to slide back and forth within said channel, and an open end of said actuator configured to slide across said outlet port, selectively exposing and covering said outlet port; a handle connected to said actuator for applying force to said actuator to open the tap by sliding said actuator in said body channel; a seal on one of said actuator and said body for engaging a seat on the other of said actuator and said body; and a spring mechanism operable between said body and said actuator for biasing said actuator in a direction for closing said slide tap by covering said outlet port, said spring mechanism configured to provide greater resistance as said actuator is moved from a closed position and lessened resistance as said actuator approaches a fully opened position. 2. The slide tap of claim 1, said handle formed integrally with said actuator. 3. The slide tap of claim 1, said spring mechanism being an elastomeric sleeve. 4. The slide tap of claim 1, said spring mechanism being a resilient deformable material. 5. The slide tap of claim 1, said handle including opposed, laterally extending wings projecting outwardly of said body. 6. The slide tap of claim 1, said body including an end cap having a depression therein. 7. The slide tap of claim 1, said spring mechanism having a leaf spring anchored in said body, and said actuator being connected to said leaf spring. 8. The slide tap of claim 1, said spring mechanism having a bow shaped member deformed when said outlet port is exposed. 9. The slide tap of claim 1, said actuator including an angled surface to direct flow through said slide tap toward said outlet port. 10. The slide tap of claim 1, said body defining an annular seat, and said actuator have a cylindrical end for engaging said seat. 11. A slide tap comprising: a body defining a channel including a first open end and an outlet port from which fluid is dispensed; an actuator slidable within said channel, said actuator having a cylindrical shape with a closed end thereof configured to slide back and forth within said channel, and an open end of said actuator configured to slide across said outlet port, selectively exposing and covering said outlet port; a handle connected to said actuator for applying force to said actuator to open the tap by sliding said actuator in said body channel; a seal on one of said actuator and said body for engaging a seat on the other of said actuator and said body; a spring mechanism operable between said body and said actuator for biasing said actuator in a direction for closing said slide tap by covering said outlet port; a frangible link connected between said actuator and said body; and wherein said actuator including a bar, and said body having a knob for engaging said bar to hold said actuator in a position exposing at least a part of said outlet port. 12. The slide tap of claim 11, said bar being connected to said body by said frangible link. 13. A slide tap comprising: a substantially cylindrical body having an inner end portion with first open end configured for receiving fluid to be dispensed from a container, an outer end portion having an end cap and a side opening, and a central portion between said inner and outer end portion; an outlet port for dispensing fluid, said outlet port defined in said central portion; a cylindrical actuator having a closed end slidable within said body along said side opening of said outer end portion, and an open end of said actuator configured to slide across said outlet port, selectively exposing and covering said outlet port; a seal formed between said actuator open end and said body when said tap is closed; and a spring mechanism operable between said body and said actuator for biasing said actuator in a direction for closing said slide tap by covering said outlet port, said spring mechanism configured to provide greater resistance as said actuator is moved from a closed position and lessened resistance as said actuator approaches a fully opened position. 14. The slide tap of claim 13, said seal including an annular channel for receiving said actuator open end. 15. The slide tap of claim 13, said spring mechanism being an elastomeric sleeve. 16. The slide tap of claim 15, said seal including a closed channel formed between said sleeve and said body, said channel configured to receive said actuator open end. 17. The slide tap of claim 13, said spring mechanism being a resilient deformable material. 18. The slide tap of claim 13, said spring mechanism having a leaf spring anchored in said body, and said actuator being connected to said leaf spring. 19. The slide tap of claim 13, said spring mechanism having a bow shaped member deformed when said outlet port is exposed. 20. The slide tap of claim 13, including a flow-directing plate disposed at an angle to the valve axis, for guiding fluid to said outlet. 21. The slide tap of claim 20, said angle being between about 45 degrees and about 60 degrees.
