Method of handling a plastic container having a moveable base

Method for processing hot-filled plastic containers are provided. In some embodiments, the method may include hot-filling a plastic container, sealing the container, and conveying the sealed container, each with an inner annular wall and a push-up portion in a first position. In some embodiments, the method may further include creating a vacuum pressure in the hot-filled and sealed container and repositioning the push-up portion from the first position to a second position under a mechanical force.

Tank cooling apparatus

A cooling apparatus includes: a pair of movable frames provided to be movable relative to each other so as to clamp a tank; multiple contact members provided on each of the pair of movable frames and each having a contact surface configured to contact an outer surface of the tank; a cooling liquid supply passage provided with multiple cooling liquid supply ports that respectively open in the contact surfaces of the contact members to supply a cooling liquid toward the outer surface of the tank; and a cooling liquid supply device that supplies the cooling liquid to the cooling liquid supply passage. Each of the contact surfaces is provided with grooves extending from a corresponding one of the cooling liquid supply ports to an outer edge of the contact surface.

Article with different textured surfaces

A method of blow molding an article having at least one layer of thermoplastic material. The method comprises the steps of heating a mold having an inner surface with two or more areas of different surface textures to a first temperature of greater than 55° C. and subsequently feeding a parison into the mold. The parison is then blown against the inner surface of the mold to form an article. The temperature of the mold is subsequently lowered to a second temperature of between 20° C. to about 55° C. and the temperature cycle time (t.sub.ct) of the mold is less than 250 seconds. Using the two phase heating and cooling process in combination with a mold featuring different surface textures provides a finished article with different visual effects.
