摘要： Multilayered containers of at least two adjacent layers having improved stress craze and crack resistances and improved rewashing wherein one of the layers is an amorphous polyamide derived from meta-xylenediamine having a glass transition temperature of at least 130°C and the other one is an aromatic polycarbonate. The containers are useful for carbonated beverages and are refillable and rewashable at elevated temperatures.

摘要： Multilayered containers comprising polycarbonate layers and amorphous polyamide layers wherein the amorphous polyamides are modified and unmodified amorphous polyamides of high glass transition temperatures. The containers have improved stress craze/crack resistance and improved rewashing properties. The containers are useful for carbonated beverages and are rewashable and refillable at elevated temperatures.

摘要： A blow molded plastic bottle (20) has a reinforced plastic bottom with a concave central portion (24) and a bottom rim portion (24). A solid depending rib (30), formed at the pinch off seam, extends across the concave portion, and depending hollow ribs (32,34), formed in the concave portion at ninety degrees to the solid rib, extend radially to the bottom rim portion. The hollow ribs effectively reduce the depth of the bottom rim intermediate the seam junctions to reduce bulging of the concave base thereby preventing instability.
