Multi-functional base for a plastic wide-mouth, blow-moulded container |
摘要 |
A blow molded container having a multi-functional base which enables use of the container in both hot-fill operations and pasteurization/retort operations and enables efficient vertical stacking of like containers. To this end, a portion of the base is capable of flexing upwardly and/or downwardly in response to variations in pressures in a filled and sealed container. Structurally, the base has a discontinuous concave outer annular wall forming a discontinuous standing ring and an inner annular wall functioning as a flex panel. The inner annular wall connects outwardly to a plurality of radial webs extending at an elevation above the standing ring and connects inwardly to an anti-inverting, upwardly-projecting dome. Preferably, a shoulder extends radially inward on the inward facing side of the outer annular wall above a level of the standing ring to facilitate vertical stacking of containers having like bases. |
