    摘要: A hollow bottle and the production method therefor. The hollow bottle of the invention is of multi-layer structure and has excellent chemical resistance and large fused adhesion strength in the pinch-off portion of the bottom. The inner layer of the bottle is made of polyamide resin and the depth of the joint groove formed in the inside surface of the inner layer in the pinch-off portion is 20% in depth as compared with the length of the pich-off portion, which portion is in a cross-sectionally tapered-off projection formed on the bottom of the bottle.In the production method of the present invention, after the multi-layer parison is extruded from dies, the lowermost end of the parison is closed and an inert gas is then blown into the parison, or the bottom of the parison is closed with blowing the inert gas. After the bottom of the parison is closed, it is transferred into a blow mold and blow molding is carried out, thereby forming a hollow bottle of the present invention.
