Abstract
Official abstract text for this publication.
A foamed and stretched plastic bottle having, in the body portion thereof, a foamed region in which foamed cells are distributed, wherein, in at least a portion of the foamed region, the lengths of the foamed cells in the axial direction of the bottle are so distributed as to gradually decrease as the positions of the foamed cells shift from the outer surface side of the body portion toward the central portion thereof and then gradually increase as their positions shift from the central portion thereof toward the inner surface side thereof. The foamed and stretched plastic bottle of the invention exhibits excellent light-shielding property.
First claim
Opening claim text (preview).
What is claimed is: 1. A foamed and stretched plastic bottle having a foamed region which is formed in a body portion and in which foamed cells are distributed, wherein said foamed region contains a portion (β), and in the portion (β), lengths of the foamed cells in an axial direction of the bottle are so gradationally distributed such that the foamed cells have a cell length that is the largest on the inner surface side of the body wall, gradually decreases toward the outer surface side, and is the smallest on the outer surface side of the body wall; wherein a skin layer free of foamed cells is formed on the outer surface side of said portion (β) of the foamed region; and wherein total light transmission factor is not more than 20% in said portion (β) of the foamed region and 20-degree specular gloss (JIS Z8741) on the outer surface of the body portion is not less than 40% in said portion (β) of the foamed region.
