A wet/dry sheet dispenser. The dispenser has an elongate refill which holds a liquid and fits into a complementary base. Liquid is selectively dispensed from the refill by longitudinal activation of a pump. The pump may be disposed on either the refill or base. Liquid flows from the refill, into the base and is ultimately dispensed onto a sheet. This arrangement allows for convenient and selective one hand pump operation, so the other hand is free to grasp the sheet. The sheet may be used wet or dry as desired at the point of use.

A refill according to claim 1 wherein said valve is removably disposed in said neck. 3. A refill according to claim 1 having a closed end remote from said neck opening, said closed end having a reclosable opening therethrough for admitting liquid into said reservoir for later dispensing in response to pumping by a user. 4. A refill according to claim 1 wherein said pump comprises a bellows disposed in said neck, said bellows providing at least a portion of said fitting. 5. A refill according to claim 4 having a longitudinal dimension of 10 to 50 cm and wherein said pump has a longitudinal stroke of 0.5 to 5 cm. 6. A refill according to claim 5 wherein said pump has a net discharge force of 10 to 40 N. 7. A refill according to claim 3 having a first cross section juxtaposed with said fitting and a second cross section juxtaposed with said closed end, said second cross section being greater than said first cross section. 8. A refill according to claim 7 having a generally round cross section, said cross section having a first diameter juxtaposed with said fitting and a second diameter juxtaposed with said closed end, said second diameter being greater than said first diameter. 9. A refill according to claim 1 wherein said reservoir further comprises a flare juxtaposed with said valve and extending radially outward therefrom. 10. A refill according to claim 9 wherein said flare circumscribes said longitudinal axis. 11. A dispenser for selective wet/dry dispensing of sheet products, said dispenser having a longitudinal axis and comprising: a base for receiving a plurality of sheets thereon, said sheets being selectively dispensible by a user;a refill disposed on said base, said refill having a longitudinal axis defining a longitudinal direction, said refill comprising:a reservoir, said reservoir comprising a hollow elongate body and an open neck;a valve disposed in said neck and in fluid communication with said reservoir, whereby said valve can dispense liquid contained in said reservoir upon demand;a fitting disposed in said base, said fitting being juxtaposed with and in operable relationship with said valve, said fitting providing for said refill to be removably disposed in said base;a pump juxtaposed with said valve and operable to dispense liquid from said reservoir to a cantilevered manifold, said cantilevered manifold having a nozzle opening juxtaposed with said valve,said manifold being in fluid communication with said fitting, said manifold and extending upwardly from said base and being juxtaposed therewith, andat least one nozzle disposed on said manifold, whereby liquid can be sprayed from said nozzle onto a sheet dispensed from said base in response to user activation of said pump. 12. A dispenser according to claim 11 wherein said base has a center, and said reservoir comprises a longitudinally oriented spindle, said spindle being juxtaposed with the center of said base to receive a roll of sheet products thereon. 13. A dispenser according to claim 12 wherein said reservoir has a closed end remote from and disposed above said valve, and said at least one nozzle is disposed 5 to 40 cm above said base and below said closed end. 14. A dispenser according to claim 11 further comprising a lock and key system complimentary to said refill and said base, whereby said lock and key system prevents said refill from being used with a base not complementary thereto and/or prevent said base from accepting a refill not complementary thereto. 15. A dispenser according to claim 14 wherein said refill further comprises a reclosable opening for replenishment of liquid from a supply to said reservoir, said refill further comprising a second lock and key system whereby said second lock and key system prevents said refill from being replenished with liquid from a supply not complementary thereto. 16. A dispenser according to claim 12 further comprising a panel, said panel being juxtaposed with a sheet being dispensed from said dispenser, said panel comprising a plurality of nozzles thereon in fluid communication with said reservoir and directed to spray a liquid pattern onto a sheet being dispensed. 17.
