| 摘要 |
This composite foam container in which foam regions, wherein foam cells (1) are distributed, are formed in the body (23) is characterized in that the foam regions comprise: a first gradient foam region (A), which has a gradient distribution such that proceeding from foam cells located toward the outer surface of the body (23) to foam cells located toward the inner surface, the maximum lengths (L) of the foam cells in the drawing direction decrease gradually; and a second gradient foam region (B), which has a gradient distribution such that proceeding from foam cells located toward the inner surface of the body (23) to foam cells located toward the outer surface, the maximum lengths (L) of the foam cells in the drawing direction decrease gradually. Said container has high resistance to pressure from the outer surface and has high liquid-draining properties while also having excellent external appearance and heat-resistance. |
