<p>A polyester bottle for beer includes an opening, a body and a bottom, which are formed once by blow moulding with polyester bottle parison. Wherein the intersection of the formed side wall of the body and the bottle bottom plane is circle arc having radius of 15-25 mm; Said bottle bottom has a concaved dome, the radius of curved dome surface is 20-35 mm, and the distance from the top of the dome to the bottle bottom plane is 7-15mm; Said dome has protrusion projecting outward formed at the bottle bottom, the height of the protrusion is 0.1-5 mm; Said side wall and the bottom of the bottle are connected with curved surfaces having various radius, wherein the radius of the first curved surface is 3-8 mm, the radius of second curved surface is 0.5-2 mm. The ratio between the maximum diameter of the bottle bottom and the diameter of said bottom protrusion is in the range of 1.2-1.7.</p> |
