to 12 panels preferably each panel 32 has at least a section 36 thereof which is flexible to accommodate induced vacuum created in a hot filled capped and cooled container in accordance with the objectives of the present invention to reduce the number of voids or the like behind a label and to enhance the prominence of the display provided by the label the flexible sections 36 are not formed as indented structures rather the flexible sections 36 of the panels 32 are formed with a slight gentle outward bow between each pair of adjacent posts 32 for example as illustrated in fig6 the section 36 is arcuate in a plane u201c p 1 u201d extending perpendicular to an imaginary central axis u201c c l u201d of the container body 10 and is formed at a predetermined radius of curvature u201c rc 1 u201d also see the cross sections of the panels 32 which are illustrated in fig3 4 and 5 along planes u201c p 4 u201d u201c p 3 u201d and u201c p 2 u201d respectively and which are formed at predetermined radius of curvatures u201c rc 4 u201d u201c rc 3 u201d and u201c rc 2 u201d respectively when the container body 10 is hot filled and capped and as the hot filled container body 10 and its contents cool a.
