Appl. No.:

09/886644

Inventors:

William C. Young - Superior Township MI
Richard C. Darr - Seville OH
Dale H. Behm - Palm Springs CA

Assignee:

Plastipak Packaging, Inc. - Plymouth MI

International Classification:

B65D 4534

US Classification:

215375, 220605

Abstract:

A plastic blow molded container ( ) is disclosed as including a freestanding base structure ( ) that is constructed with a plurality of alternating hollow legs ( ) and curved ribs ( ), and a hub ( ) from which the legs and ribs extend radially with a construction that provides good stability against tipping as well as the capability of withstanding internal pressure. Each rib ( ) has an outer upper end ( ) with a circumferential width W and an inner lower end ( ) with a circumferential width W that is greater than the circumferential width W of the upper rib end so the lower rib end is capable of resisting stress cracking. An intermediate rib portion ( ) of a curved shape tapers between the ends with an included angle B in the range of about 1Â to 8Â and preferably about 2Â. The specific construction disclosed of the legs ( ), ribs ( ) and hub ( and â) enhance the capability of the base structure in providing good stability as well as the capability of withstanding internal pressure and stress cracking.

Abstract:

A plastic blow molded container () is disclosed as including a freestanding base structure () that is constructed with a plurality of alternating hollow legs () and curved ribs (), and a hub () from which the legs and ribs extend radially with a construction that provides good stability against tipping as well as the capability of withstanding internal pressure. The legs () have lower flat feet () with an outer diameter D, and the hub () has a periphery connected to the feet and ribs with a height Hsuch that the ratio of the diameter Dover the height His in the range of about 25 to 90 to maintain strength without the hub engaging the supporting surface on which the feet rest. The construction disclosed of the legs (), ribs () and hub (41, 41′ and 41″) enhances the capability of the base structure in providing good stability as well as the capability of withstanding internal pressure and stress cracking.
