A hot-fillable wide-mouth jar having an opposed pair of collapse panels that move inwardly to accommodate vacuum-induced volumetric shrinkage of the jar. The jar includes a sidewall having front and rear label panels each of a predetermined radius of curvature and each of a predetermined arcuate extent. A pair of arcuate collapse panels are located between the front and rear label panels, and each has a predetermined arcuate extent and an inset grip region affording facile handling of the jar. Desirable structural parameters are disclosed.

1. A hot-fillable wide-mouth grip jar, comprising:a dome with a wide-mouth finish, said dome having a lower portion with a circular transverse cross-section; a base having an upper portion with a circular transverse cross-section located below said dome and coaxially therewith, a sidewall extending between said dome and base portions, said sidewall having diametrically opposed front and rear label panels and opposed collapse panels disposed between said label panels, each collapse panel having an inset grip region affording facile gripping of the container; each of said label panels having a predetermined transverse radius of curvature throughout its arcuate extent for providing an inwardly concave surface; each of said collapse panels having throughout its arcuate extent a predetermined radius of curvature greater than either of said label panels for providing an inwardly concave surface; the lateral extent of each of said collapse panels being defined by a front transitional zone located at the juncture of said front label panel and said collapse panel radii of curvature and by a rear vertical transitional zone, each of said front transitional zones being a smooth arcuate wall section which smoothly transitions and merges said radius of curvature of said collapse panel into said radius of curvature of said front label panel, said radius of curvature of said front label panel being substantially constant between horizontally opposed front transitional zones; the vertical extent of each of said collapse panels being defined by a continual arcuate upper peripheral stiffener subjacent said dome lower portion and a continual lower peripheral stiffener located superadjacent said base upper portion such that each collapse panel merges into said upper and lower peripheral stiffeners; said collapse panel moving inward in response to forces developed in the jar in response to hot-filling with a liquid, capping and cooling; and each of said grip regions being offset rearwardly in its collapse panel so as to be located closer to said rear label panel than to said front label panel, and each of said front transitional zones forming a wide generally C-shaped, inwardly-concave smooth wall portion extending around a substantial portion of said grip region.
