  • Publication number: 20040149677
    Abstract: A plastic container comprised of a closed base, a body portion, and a neck portion with a dispensing opening. The closed base includes a substantially rigid support portion and a flexible portion. The body portion preferably includes a shoulder portion and a substantially rigid wall portion that includes a plurality of reinforcement formations. The container is configured so that the flexible portion of the base contracts upwardly about the support portion in response to vacuum pressures generated within the container, while the substantially rigid support portion of the sidewall remains substantially firm, for example, to accept or receive a label. If desired, the shoulder portion may include a logo and/or one or more pressure relief formations. A method for producing hot-filled, labeled containers is also disclosed.

  • Patent number: 6740284
    Abstract: A plastic blow molded container having a central vertical axis constructed in accordance with the present invention includes a cylindrical upper rim, an oriented neck portion, a lower body portion, and a closed base portion. The upper rim of the container includes a top surface having a planar inner edge and an outer edge. The inner edge is generally flat and perpendicular to the vertical axis of the container and the outer edge may be curled or curved to provide additional rigidity. The oriented neck portion depends from the upper rim and includes a means to accept a closure, such as a set of integral threads. When viewed in vertical cross section, the outer vertical line formed by the outer axial points of said means to accept a closure is substantially parallel to the vertical axis of the container. The lower body portion is generally cylindrical over the majority of its vertical length. The closed base portion supports the container and depends from the lower body portion.

  • Publication number: 20040079721
    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. The legs (22) have lower flat feet (24) with an outer diameter Df, and the hub (41) has a periphery connected to the feet and ribs with a height Hp such that the ratio of the diameter Df over the height Hp is 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 (22), ribs (34) 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.

  • Patent number: 6659299
    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°.

  • Patent number: 6641774
    Abstract: A preform for forming a hollow blow molded plastic container is provided with a closed base, a multilayer body-forming portion extending from the base, and an open neck portion that extends from the body portion. The body portion includes a co-extruded inner liner that includes (a) an innermost polymer layer, (b) at least one oxygen-scavenging layer, and (c) at least one high-oxygen barrier layer for retarding the migration of gases and moisture therethrough. An outermost layer is molded over the inner liner to form a preform. The liner and preform are formed so that the wall thickness of the individual layers can easily be varied along their lengths, however, at any given point along the length of the co-extruded liner (a) the wall thickness of the innermost polymer layer is less than 0.50 of the wall thickness of the inner liner and (b) the wall thickness of the inner liner is less than 0.25 of the total wall thickness of the preform body portion.
