Blow Moulded Bottle, Method of Manufacturing and Mould

摘要

A blow moulded plastic bottle includes a neck, a shoulder, a tubular body portion, and an integral bottom structure including: a terminal curved portion, an internal axially inwardly directed dome, and an (annular) base joining the terminal curved portion to the dome; wherein: a spline comprises a flat part in the base plane (Pb) onto the bottle rests when it stands up; the height (h1) between (Pb) and the apex of the dome, the height (h2) between (Pb) and the spline diametral median plane (Pd) which is in the middle of the spline (17) and which is parallel to (Pb), and the maximum external diameter (Dm) of the tubular body portion, being so that [(h1)/(Dm)]*100 is comprised between 14.0 and 16.0% and (h1)<(h2)≦3.5(h1).
