A synthetic resin bottle which can be deformed and reduced in volume easily, sufficiently flatly and restorably by forming at least one reversal line at the shoulder part, the body part and the bottom part of the bottle body over the entire circumference in the longitudinal direction, making at least one of sections delimited by the reversal lines serve as a shell part where at least the body part has a relatively high rigidity substantially entirely, making other sections serve as resiliently reversible parts where at least the body part has a relatively low rigidity substantially entirely, standing a tubular mouth part at the shoulder part, and arranging the entire reversible parts so as to retract easily into the shell part and to restore to the original shape. L'invention concerne une bouteille en résine synthétique susceptible d'être aisément déformée et réduite en volume de façon suffisamment plate, avec restitution de la forme originale. A cet effet, on établit au moins une ligne de réversibilité sur l'épaule, le corps et le fond, couvrant toute la circonférence dans la direction longitudinale, pour qu'au moins l'une des sections délimitées par les lignes de réversibilité serve de coque et qu'au moins le corps présente une rigidité relativement élevée sensiblement sur toute son étendue. On fait en sorte que les autres sections soient des parties réversibles souples, et qu'au moins le corps ait une rigidité relativement peu élevée sensiblement sur toute son étendue, l'embouchure tubulaire ressortant de l'épaule, et les parties entièrement réversibles se rétractant aisément dans la coque pour la restitution de la forme originale.
