    Abstract: A plastic blow molded container (10) is disclosed as including a freestanding base structure (20) that is constructed with a plurality of alternating hollow legs 22 and curved ribs (34), and a hub (41) 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 (34) has an outer upper end (36) with a circumferential width Wu and an inner lower end (38) with a circumferential width Wl that is greater than the circumferential width Wu of the upper rib end so the lower rib end is capable of resisting stress cracking. An intermediate rib portion (40) of a curved shape tapers between the ends with an included angle B in the range of about 1° to 8° and preferably about 2°. The specific construction disclosed of the legs, ribs (34) and hub (41, 41′, 41″) 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 (10) including a coextruded blow molding (12) has a wall (22) including: (a) an inner layer (26) of a virgin plastic; (b) an inner intermediate layer (28) of recycled plastic which is relatively dark; (c) an outer intermediate layer (30) of an opaque plastic that visually hides the dark recycled plastic; and (d) an outer layer (32) of a pigmented plastic of a lighter color which is not visually distorted by the darker inner intermediate layer (28) of recycled plastic due to the opaqueness of the outer intermediate layer (30). Titanium dioxide is preferably utilized to provide the opaqueness of the outer intermediate layer (30) in order to visually block the darker color of the recycled plastic of the inner intermediate layer (28). The inner layer (26) of virgin plastic, the outer intermediate layer (30) of opaque plastic and the outer layer (32) of pigmented plastic each has a thickness that is at least about 0.1 of the total thickness of the wall, and the inner intermediate layer (28) of recycled plastic normally will have a thickness on the order of about 0.55 to 0.65 of the total thickness of the wall. The construction of the container has particular utility when the wall 22 including each of its layers is made of high density polyethylene.
