Abstract: 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.

Abstract: A stretched and foamed plastic formed body forming, in at least a portion thereof, a foamed region which incorporates foamed cells therein, wherein the foamed cells have a flat shape with a maximum thickness of not more than 30 ?m and an average aspect ratio of not less than 4 as viewed in cross section of the formed body perpendicular to a direction in which the formed body is stretched to a maximum degree, and a non-foamed plastic skin layer having no foamed cell distributed therein is formed on the outer surface of the foamed region. The formed body is, further, blended with a non-lustrous pigment as the coloring agent, which is different from a lustrous pigment such as flaky pigment, and exhibits a metal color over the foamed region thereof. The foamed formed body exhibiting a metal color and, specifically, a gold color or a silver color is thus provided without using any expensive lustrous pigment such as metal powder pigment or flaky pigment.

Abstract: A foamed and stretched plastic container having a basic structure which includes a mouth portion and a body wall continuous to the mouth portion and is stretch-formed, the body wall forming a foamed region where foamed cells are distributed, and the mouth portion being an unfoamed region where no foamed cell is present, wherein the foamed cells present in the foamed region have a flat shape being stretched in the direction of stretch, and the foamed cells positioned in the central portion in the direction of thickness of the container wall have the largest lengths in the direction of maximum stretch.

Abstract: The file is equipped with a plurality of bags, which are vertically stacked, between the front cover and the back cover being unfoldable. The vertically adjoining bags are connected by way of the connecting part one to another and the upper bags can be shifted from the lower bags in the direction opposite to the opening section within the allowable range of the connecting part so that the opening section of the lower bags may be exposed from the upper bags. The knob is provided on the uppermost bag.
