COMPOSITE FOAM CONTAINER

摘要

A composite foamed container forming, in the body portion 23, thereof, a foamed region in which foamed cells 1 are distributed, the foamed region including a first gradationally foamed region A having a gradational distribution of the foamed cells of which the length L in the direction of maximum stretch gradationally decreasing from the outer surface side of the body portion 23 toward the inner surface side thereof and a second gradationally foamed region B having a gradational distribution of the foamed cells of which the length L in the direction of maximum stretch gradationally decreasing from the inner surface side of the body portion 23 toward the outer surface side thereof.
The container has a large resistance against the pressure exerted on the outer surface, good liquid-dispelling property and, at the same time, has improved appearance and heat resistance.
