An extrusion blow molded container is provided comprising a closed base, a body portion extending from the closed base having a surface finish that is substantially free of striations, and an open neck portion extending from the body portion. In an embodiment, the container is comprised of polyethylene terephthalate (PET); the base portion includes a support portion and a substantially elevated portion having a center and a major diameter; and the center is disposed an elevated distance above said surface that is less than about 0.05 the major diameter. A method and apparatus for extrusion blow molding an article is also disclosed.

Extrusion blow molded container, apparatus and method

A method for making a container including a radio frequency identification label is provide. In an embodiment the method includes placing a radio frequency identification (RFID) label into a mold; positioning the RFID label so that an outer portion of the label is substantially flush with the mold surface; and molding a container such that the outer portion of the RFID label is substantially flush with the outer surface of the side wall of the container. An article, which may be formed using the foregoing method, is also disclosed.

Application of radio frequency identification

A plastic container with the sidewall thereof including a label panel and a label adhered to the label panel. The label includes micro-optics as at least part of the label to create an image of depth in the micro-optic area.

Blow molding apparatus having raised pinches and compression lands

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.
