A bottle cap remover includes a pair of axially nested socket sections of different diameters depending axially from a larger-diameter grasping section. Each of the socket sections includes frictional gripping members along their inner walls that are adapted to frictionally engage different sizes and types of metal and plastic bottle caps, thereby to enable the user to twist off and remove the bottle caps by applying a relatively small twisting force to the grasping section.

What is claimed is: 1. A bottle cap remover comprising a grasping portion having a first diameter, a first cap-removing section coaxially depending from said grasping portion and having a second diameter less than that of said first diameter and that corresponds to the diameter of a first-sized bottle cap, and a second cap-removing section coaxially depending from said first cap-removing section and having an outwardly and downwardly tapering inner circumferential wall, said second cap-removing section having a continuously varying diameter greater than said second diameter and corresponding to a range of bottle cap sizes, the inner walls of said second cap-removing section including a plurality of axial splines or ribs which are tapered to a greater degree than the wall of said second cap-removing section, said splines or ribs having a cross-section that varies from a vee-shaped form at the largest diameter portion of said second cap-removing section to a half-round or semi-circular form at the smallest diameter portion of said second cap-removing section for frictionally and mechanically engaging the peripheries of said range of bottle caps. 2. The bottle cap remover of claim 1, in which a second plurality of splines or ribs are provided along the inner wall of said first cap-removing section. 3. The bottle cap opener of claim 2, in which said plurality of vee-shaped tapered splines or ribs are joined are joined in a colinear form, and wherein said plurality of splines or ribs which are half-round or semi-circular are joined to said vee-shaped splines in the form of a partial dome. 4. The bottle cap remover of claim 1, in which said grasping portion includes a plurality of arcuate recesses formed about its periphery for receiving a user's fingers. 5. The bottle cap remover of claim 1, in which said plurality of vee-shaped tapered splines or ribs are joined in a colinear form, and wherein said plurality of splines or ribs which are half-round or semi-circular are joined to said vee-shaped splines in the form of a partial dome. 6. The bottle cap opener of claim 1, in which a plurality of peripheral segments are defined intermediate said arcuate recesses of said grasping portion, and wherein a slot of rectangular cross-section is formed in at least one of said peripheral segments for engaging the closure tab of a can, said slot including a tapered wall to mechanically aid in the lifting of the closure tab. 7. A bottle cap remover comprising a grasping portion having a first diameter and a cap-removing section coaxially depending from said grasping section and having an outwardly and downwardly tapering inner circumferential wall, said cap-removing section having a continuously varying diameter greater than said first diameter and corresponding to a range of bottle cap sizes, the inner walls of said cap-removing section including a plurality of axial splines or ribs which are tapered to a greater degree than the wall of said cap-removing section, said splines or ribs having a cross-section that varies from a vee-shaped form at the largest-diameter portion of said cap-removing section to a half-round or semi-circular form at the smallest-diameter portion of said cap-removing section for mechanically engaging the peripheries of said range of bottle caps. 8. The bottle cap remover of claim 7, in which said grasping portion includes a plurality of arcuate recesses formed about its periphery for receiving a user's fingers. 9. The bottle cap remover of claim 8, in which a plurality of peripheral segments are defined intermediate said arcuate recesses of said grasping portion, and wherein a slot of rectangular cross-section is formed in at least one of said peripheral segments for engaging the closure tab of a can, said slot including a tapered wall to mechanically aid in the lifting of the closure tab. 10. The bottle cap remover of claim 7, in which said plurality of tapered vee-shaped splines or ribs are joined in a colinear form and wherein said plurality of splines or ribs which are half-round or semi-circular are joined to said vee-shaped splines in the form of a partial dome. 11. A bottle cap remover comprising an upper grasping portion having a first diameter, a first cap-removing section coaxially depending from said grasping portion and having a second diameter less than said first diameter, said second diameter corresponding to the diameter of a first-sized bottle cap, and a second cap-removing section depending coaxially from said first cap-removing section and having a third outwardly tapering diameter greater at its smallest diameter segment than said second diameter, said tapering diameter corresponding to the diameters of a variety of different-sized bottle caps each of a greater diameter than said first-sized bottle cap, said first and second cap-removing sections including a first and second plurality of splines or ribs circumferentially respectively spaced along their inner walls, said first and second plurality of splines or ribs having respectively different cross-sections and respectively spaced circumferentially from one another by a distance corresponding to the spacing between the recessed segments formed about the peripheries of said first-sized and different-sized bottle caps for respectively mechanically engaging the peripheries of said bottle caps. 12. The bottle cap remover of claim 11, in which said first plurality of splines or ribs are tapered and are half-round or semi-circular in cross-section and said second plurality of splines or ribs are vee-shaped in cross-section.
