PROBLEM TO BE SOLVED: To provide a disposable plastic bottle, which prevents the accumulation of contents, does not turn to its original state, and enables a separate disposal of a cap and the bottle. SOLUTION: The plastic bottle (10) is crushable, and has a trunk (12), a mouth (11) thinner than it, and a shrinkable film (20) fitted on the trunk (12). Bellows-shaped or spiral-shaped grooves (13) are formed on the trunk (12), and a hole (21) having a diameter slightly larger than that of the mouth of the plastic bottle (10) is drilled on an upper part of the shrinkable film (20), on which two perforated lines (a, a) opposed to each other across the hole (12) are formed to be extended downward from the upper end of the film (20) at a certain length.
