<p>Bottle (10) having an improve bearing base (20) capable to fully accommodate and hold its reusable stopper (30) while keeping bottle's upright stability. The base inn er walls are forming cup like seat that holds stopper at four sides (24) to keep stopper in place using elastic properties of plastic materials used for bottle and stopper, and friction between surfaces of bottle and stopper. The cup-like seat has a rounded entry (28) into the inner part of the bottle base, so stopper (30) can find its way into the cup-like seat easily. After the rounded entry , stopper's circumference is getting in touch with the inner walls of the recessed base (24) that are from that point gently conical. With further travel of stopper, until it is completely positioned within the base, the holding of a stopper is achieved by elastic deformation and friction between stopper and bottle's recessed base inner walls (24). This shape provides easy placing of stopper in the recessed base and room fo r fingers to take the stopper out. The stopper can also be placed in by putting the bottle bas e on the top of the stopper that is laid on some surface (table) with the hollow side up.</SDOAB ></p> |
