Abstract
A perspective receptacle charged with liquid and having its mouth portion sealed with an opaque seal member is rotated as-erected at a high speed. Due to this high speed rotation, the air resident in the vicinity of the mouth portion of the receptacle forms an air cavity and descends below the seal member. This descending air cavity is detected from the outside of the receptacle by means of an optical detecting member.
