<p>The invention relates to a semihard container with acollapsable part (7) consisting of multiple diamond-shapedsegments (112) forming a truncated cone. The segments (112) arerounded to match the connecting base (111) laterally andlongitudinally so that they may resist any expansion under theeffect of pressure from the interior of the container and be ableto extend laterally in order to facilitate the folding of thecollapsable part (7) under the effect of the longitudinalshrinking force which prevents the extension in folded position.The invention also relates to other shapes of the segments (112).</p> |
