Bottle for hot filling use, equipped with vacuum absorption panels in the body portion

摘要

This invention is titled "Bottle for hot filling use, equipped with vacuum absorption panels in the bottle portion." The purpose of this invention is to provide a PET bottle having structurally improved vacuum absorption panels in the bottle portion so as to increase the panels' resistance to the constricting force of the shrink label, to secure the force of restitution for the panels, and thereby to allow the liquid level in the bottle to lower when the cap is opened. The means to achieve this purpose is given by the vacuum absorption panels in a configuration comprising multiple, flat and variable surfaces (15) and (20), which somewhat stand back from the plane of each corresponding main body wall; and multiple, horizontal and grooved ribs (16) and (21) having respectively a curved bottom (18) with the middle portion of this bottom being slightly uplifted, and with each rib being placed under a variable surface in an alternately disposed manner.
