摘要:
A wide-mouth plastic container is formed from a preform that is blow-molded to form an intermediate container article that has blown threads located below a moil. The moil is severed above the blown threads to yield the finished container. A preform and process for manufacturing the wide-mouth container are disclosed.
摘要:
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.

摘要:
A container dome with arch-like structures in elevation and polygon-shaped structures in plan. The arch-like structures are provided by pairs of chordal stiffening facets disposed in an endwise adjacent array extending transversely about the periphery of the dome to enhance top loading capability. Each pair of facets has an inwardly-convex chordal stiffening rib which defines a regular transverse polygon having an uneven number of sides to prevent dome ovalization. Preferably, multiple vertically-stacked tiers of facet pairs arrays are utilized with each array being radially offset from adjacent tiers.
