A plastics material bottle is collapsible by applying axial compression, the bottle comprising a cylindrical body having a polygonal cross-section, e.g. a section that is substantially square or rectangular with rounded corners (18), the body being formed with transverse fluting grooves (14) which include fold starters (16) situated in the immediate vicinity of the above-mentioned rounded corners (18). The invention is particularly applicable to bottles for containing beverages such as mineral water, for example.

[ We claim:] [1.] A plastics material bottle that is collapsible when empty by applying axial compression in a direction defined by a longitudinal axis of the bottle, the bottle comprising a cylindrical body formed with substantially V-section transverse fluting grooves and with outwardly-projecting fold starters formed locally on the bottoms of the fluting grooves, the body having a generally polygonal cross-section normal to the bottle axis, the polygonal cross-section having rounded corners and the fold starters being formed in the immediate vicinity of the rounded corners of the polygonal cross-section of the body.
