A backpack (10) suitable for use with wheels (200) at its base adjacent to a non body-contact side (40) has a U-shaped opening (22) proximate to a body-contact side (30) that is closed with a zipper (31). The body-contact side (30) is provided with two shoulder straps (34) and a hip belt (36). Side
A backpack (10) suitable for use with wheels (200) at its base adjacent to a non body-contact side (40) has a U-shaped opening (22) proximate to a body-contact side (30) that is closed with a zipper (31). The body-contact side (30) is provided with two shoulder straps (34) and a hip belt (36). Side straps (130) and a top flap or strap (134) connect the body-contact side (30) to other parts of the backpack (10), such as the non body-contact side (40), to take a substantial part of the weight of the backpack (10) and its contents so that the zipper (31) is not stressed or tensioned when the backpack (10) is worn on the back of a user. The wheels (200) are removable and can be larger than is usual for use on rough ground. A frame (100) with a built-in extending handle system (120) is mounted inside and ajacent to the non body-contact side (40).

The system of claim 1, wherein the cover is composed of a single piece of material having an aperture which defines an opening aligned in parallel relation to the fold axis of the flexible base. 9. The system of claim 1, wherein the opening in the flexible cover is fitted with a closure means selected from zippers, clasps, clamps, snap fasteners, hook and loop fasteners, straps, ties, and hooks. 10. A portable folded wiper system for dispensing flexible sheets from a stack of sheets, the system comprising a refillable apparatus and a stack of sheets, the refillable apparatus comprising: a relatively flat, flexible base devoid of dispensing slots, said flexible base being formed of a foamed polymeric material and adapted to resiliently fold along a fold axis, the fold axis of the flexible base being a longitudinal fold axis; and a flexible cover defining an opening aligned in parallel relation to the fold axis of the flexible base, said flexible cover being formed of a single piece of foamed polymeric material which is attached to said flexible base and adapted to contain a stack of sheets; said opening defining a dispensing slot through which flexible sheets may be individually dispensed while said flexible base remains unfolded, and said opening defining a refill gap through which a stack of flexible sheets may be inserted when said flexible base is folded back along the fold axis, wherein the flexible base requires from about 2 to about 5 pounds force to fold it back along its longitudinal axis so that the opening in the cover defines a refill gap through which a stack of flexible sheets may be inserted. 11. The system of claim 10, wherein the stack of sheets are in the form of a pack of sheets within a plastic wrap provided with an aperture along a major face of the pack which conforms to the dispensing slot of the apparatus. 12. The system of claim 10, wherein the foamed polymeric material is composed of foamed poly(ethylene-vinyl acetate) having a density ranging from about 160 kg/m3to about 240 kg/3. 13. The system of claim 12, wherein the foamed polymeric material is composed of foamed poly(ethylene-vinyl acetate) having a density ranging from about 200 kg/m3. 14. The system of claim 10, wherein the flexible base includes attachment means. 15. The system of claim 10, wherein the opening in the flexible cover is fitted with a closure means. 16. A portable folded wiper system for dispensing flexible sheets from a stack of sheets, the system comprising a refillable apparatus and a stack of sheets, the refillable apparatus comprising: a relatively flat, flexible base devoid of dispensing slots, said flexible base being formed of a foamed poly(ethylene-vinyl acetate) material having a density ranging from about 160 kg/m3to about 240 kg/m3and adapted to resiliently fold along a longitudinal fold axis; and a flexible cover defining an opening aligned in parallel relation to the longitudinal fold axis of the flexible base, said flexible cover being formed of a single piece of foamed poly(ethylene-vinyl acetate) having a density ranging from about 160 kg/m3to about 240 kg/m3which is attached to said flexible base and adapted to contain a stack of sheets; said opening defining a dispensing slot through which flexible sheets may be individually dispensed while said flexible base remains unfolded, and said opening defining a refill gap through which a stack of flexible sheets may be inserted when said flexible base is folded back along the longitudinal fold axis, wherein the flexible base requires from about 2 to about 5 pounds force to fold it back along its longitudinal axis so that the opening in the cover defines a refill gap through which a stack of flexible sheets may be inserted. 17. The system of claim 16, wherein the stack of sheets are in the form of a pack of sheets within a plastic wrap provided with an aperture along a major face of the pack which conforms to the dispensing slot of the apparatus. 18. The system of claim 16, wherein the foamed poly(ethylene-vinyl acetate) has a density of about 200 kg/m3. 19. The system of claim 16, wherein the flexible base includes attachment means. 20. The system of claim 16, wherein the opening in the flexible cover is fitted with a closure means. 21. The apparatus of claim 1, wherein the flexible base requires from about 2 to about 5 pounds force to fold it back along its longitudinal axis so that the opening in the cover defines a refill gap through which a stack of flexible sheets may be inserted. 22. The system of claim 16, wherein the flexible base requires from about 3 to about 4 pounds force to fold it back along its longitudinal axis so that the opening in the cover defines a refill gap through which a stack of flexible sheets may be inserted.
