    摘要: A transparent liquid container bottle features a label with a tinted backside which imparts a tinted appearance to the contained liquid. The bottle has a cylindrical body, a hemispherical top and a base cup. The base cup may be tinted to match the backside of the label. The label covers only part of the cylindrical body, leaving an unlabeled section with a dimension 0.1 to 2.0 times, or 0.5 to 1.2 times preferably, the diameter of the body.
