Bottle (10) having an improved bottle wall (11) capable to hold its reusable stopper (14) while keeping bottle's upright stability. The bottle walls are forming bay with cup like seat that holds stopper in place using elastic properties of plastic materials used for bottle and stopper, and friction between surfaces of bottle and stopper. The bay has a shallow and wide entry (17) on the top. From the entry point, going down, the bay gains depth and becomes narrower towards the low bay point, so stopper (14) can find its way into the cup-like seat easily. After the wide entry, stopper's circumference is getting in touch with the inner walls of the recess (15) that are from that point gently conical. With further travel of stopper, until it is completely positioned within the bay, the holding of a stopper is achieved by elastic deformation and friction between stopper (14) and bottle's recessed walls (15. Conical walls at the bay bottom may be slightly widened (relaxed) so "click" sensation is achieved when stopper slides in.. This shape provides easy placing of stopper in the recessed wall (bay) from the top and room for fingers at low point (16) to take the stopper out.
