摘要

A disposable bottle (1) having a gradually collapsible structure, of the type in which the sidewalls (2) of the bottle have an accordion-like structure comprising several adjacent folds. Each fold is formed by two opposed surfaces (7, 8) of different width, comprising blocking means to prevent the recovery of the fold, under a predetermined force, once the same fold has collapsed for the first time.
