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:
An ergonomically friendly container (10, 30) having hot-fill capabilities is disclosed. The container (10, 30) has a pre-ovalized dome (14, 34) with grip surfaces (20, 21, 40, 42) that undergo controlled deformation for accommodating a portion of the volumetric shrinkage due to hot-filling, capping, and cooling. Preferably, anti-racking ribs (32a, 32b) extend laterally between the grip surfaces (20, 21, 40, 42) to prevent unwanted racking or twisting of the dome (14, 34) during vacuum absorption.
