Abstract: This invention relates to a low cost, portable interactive balance board having a platform on a rocker pivot and integral electronics that provides the user commands, commentary and feedback. Specifically the integral electronics comprise at least one or more of a light source, an audio source and a tilt sensor. The inexpensive, interactive and unique experience of a device made according to this invention, make it suitable for exercising, rehabilitation, challenges or training.

Abstract: The invention provides a light weight self-standing blow molded two liter carbonated beverage bottle having a unique petaloid base made from a monobase preform. The base comprises a petaloid design which has a plurality of at least three (preferably five) feet. The monobase preform has a thick reinforcing ring forming portion which remains unstretched during blowing. The reinforcing ring forming portion is thicker than both the sidewall forming portion and the gate area forming portion of the preform thereby resulting in increased stretching in both those areas. The reinforcing ring extends circumferentially around the base. By providing such a reinforcing ring, a bottle having a bigger foot radius and/or containing less material use can be realized. The resulting bottle has less stress whitening and greater stress crack resistance while at the same time using less material and/or having a larger radius than prior bottles.

Abstract: The invention provides a light weight self-standing blow molded two-liter carbonated beverage container base design having a unique petaloid base. The base comprises a petaloid design which has a plurality of at least three (preferably five) feet with an ever increasing radius of curvature joining the feet to the underlying base from the radially outer portion of the feet to the radially inner portion of the feet, a controlled radius from the axis of the container to that curvature and an area of material flow in feet ankles and straps therebetween to promote adequate material flow during blow molding, to the radially outer most areas of the feet and straps.

Abstract: A process for injection molding a multi-colored article in an injection mold, in which a) a desired initial quantity of a first-colored material is metered to a first desired portion of the cavity; b) a desired quantity of a second-colored material is supplied to the cavity, contiguously with the first-colored material, and is metered to a second desired portion of the cavity. The location of the first and second desired portions within in the cavity being controlled by providing the first and second-colored materials with appropriate melt viscosities and controlling the temperature and rate of supply of the first and second-colored materials. A multi-colored preform formed by the process that is suitable for blow molding a multi-colored container, and a multi-colored container blow molded from such a preform are also provided.
