1. A refillable container system comprising: a. a base having a partial bottom terminating at an inner perimeter edge defining a bottom opening, at least one rib extending upward from and defining at least in part the inner perimeter edge, a continuous side wall extending up from the partial bottom and terminating at an upper end, a space within the side wall above the partial bottom, and an open top bounded by the upper end; b. a refill cartridge having a bottom, a continuous side wall extending up from the cartridge bottom and terminating at an upper end, a space within the side wall above the cartridge bottom, and an open top bounded by the upper end; and c. a lid configured to close off the open top of the base near the upper end of the base side wall.

2. The refillable container system of claim 1 further comprising a wiping substrate disposed in the refill cartridge.

3. The refillable container system of claim 1 further comprising a hinge operatively connecting the base and the lid.

4. The refillable container system of claim 1 wherein the refill cartridge bottom is sized to completely cover the bottom opening of the base.

5. The refillable container system of claim 1 wherein the refill cartridge contacts the at least one rib.

6. The refillable container system of claim 1 wherein the rib extends continuously around the inner perimeter edge of the partial bottom.

7. The refillable container system of claim 1 wherein the at least one rib has a front, a back and a pair of opposed side edges, wherein the height of the back edge is greater than the height of the front edge.

8. The refillable container system of claim 1 wherein the refill cartridge has a rim extending from the upper end and substantially perpendicular to the side wall.

9. A refillable wiping substrate dispenser: a. a base having a partial bottom terminating at an inner perimeter edge defining a bottom opening, at least one rib extending upward from and defining at least in part the inner perimeter edge, a continuous side wall extending up from the partial bottom and terminating at an upper end, a space for receiving a refill cartridge within the side wall above the partial bottom, and an open top bounded by the upper end; b. a refill cartridge disposed within the base, the refill cartridge having a bottom, a continuous side wall extending up from the cartridge bottom and terminating at an upper end, a storage space for receiving a wiping substrate within the side wall above the cartridge bottom, and an open top bounded by the upper end; c. a wiping substrate disposed within the refill cartridge; and d. a lid configured to close off the open top of the base near the upper end of the base side wall.

10. The refillable wiping substrate dispenser of claim 9 wherein the refill cartridge bottom is sized to completely cover the bottom opening of the base.

1 1. The refillable wiping substrate dispenser of claim 9 wherein the bottom opening comprises from about 50 to about 90 percent of the total bottom area of the base.

12. The refillable wiping substrate dispenser of claim 9 wherein the at least one rib extends continuously around the inner perimeter edge of the partial bottom.

13. The refillable wiping substrate dispenser of claim 9 wherein the refill cartridge has a rim extending from the upper end and substantially perpendicular to the side wall, the rim contacting the base.

14. A refillable wiping substrate dispenser: a. a base having a partial bottom terminating at an inner perimeter edge defining a bottom opening, at least one rib extending upward from and defining at least in part the inner perimeter edge, a continuous side wall extending up from the partial bottom and terminating at an upper end, a space for receiving a refill cartridge within the side wall above the partial bottom, and an open top bounded by the upper end; b. a refill cartridge disposed within the base, the refill cartridge having a bottom, a continuous side wall extending up from the cartridge bottom and terminating at an upper end, a storage space for receiving a wiping substrate within the side wall above the cartridge bottom, and an open top bounded by the upper end, the refill cartridge contacting the base and covering the bottom opening; c. a wiping substrate disposed within the refill cartridge; and d. a closure comprising a base member having a peripheral skirt, a sealing member having a central opening and a cap, the closure configured to close off the open top of the base near the upper end of the base side wall.

15. The refillable wiping substrate dispenser of claim 14 wherein the refill cartridge bottom is sized to completely cover the bottom opening of the base.

16. The refillable wiping substrate dispenser of claim 14 wherein the sealing member is operatively connected to the base member by a hinge and the sealing member is connected to the cap by a hinge.

17. The refillable container system of claim 14 wherein the at least one rib extends continuously around the inner perimeter edge of the partial bottom.

18. The refillable container system of claim 14 wherein the at least one rib has a front, a back and a pair of opposed side edges, wherein the height of the back edge is greater than the height of the front edge.
