Hot-fillable, blow molded, wide-mouth plastic containers having a pair of flex panels (11, 111, 211) for accommodating thermally induced volumetric and pressure variations while affording easy contents scoopability, and desirable labeling features. The containers are capable of being blow-molded from injection molded preforms or from extruded parisons. The containers may be hot-filled and retorted. A desirable base (27, 127, 227) for a retortable container is also disclosed.

1. In a widemouth blow-molded container having a dome (23) with a finish (25, 125), a base (27, 127, 227), and a body (10) connecting the dome (23) to the base (27, 127, 227), said body (10) having an arcuate front label panel (13, 113) and an arcuate rear panel (15, 115), the improvement comprising:a pair of flex panels (11, 111, 211) in the body (10) for accommodating internal changes in pressure and volume in the container resulting from heating and cooling of its contents, said flex panels (11, 111, 211) being disposed opposite one another in said container body (11), and each flex panel (11, 111, 211) being planar, as manufactured, said rear label panel (15, 115) being of lesser peripheral extent than said front label panel (13, 113), and said flex panels (11, 111, 211) extending chordally between said front and rear panels (13, 15, 113, 115) and tapering toward one another to subtend a dihedral angle therebetween, whereby the flex panels (11, 111, 211) enhance contents scoopability.
