Abstract
The present invention provides a liquid filling method capable of filling liquid into containers at a rate as high as 3500 containers/nozzle.multidot.hour (2 pitch-feed) without causing the problems such as foaming, turbulence of liquid surface and the like inside the container, and a high-speed liquid filling machine used in said method. In said method, liquid is filled into a container that had been intermittently carried in a sequential manner to a filling station by raising and lowering said container, the filling is started when the container is raised before it reaches the upper dead point of raising and lowering, the container is filled with a specified amount of liquid at the upper dead point of raising and lowering, and then filling is continued while lowering the container. It is preferable for the filling to be started before the carrying of the container is stopped, for example, the start of the filling to be advanced 30.degree. to 70.degree. from the upper dead point of raising and lowering in one raising and lowering cycle of 360.degree.. Furthermore, it is preferable for the carrying to be started before the lowering of the container is finished, wherein the start of carrying the container is advanced 40.degree. to 70.degree. from the end of lowering in one raising and lowering cycle of 360.degree..
