Blow-molded lamination container and manufacturing method thereof

A manufacturing method of a blow-molded lamination container comprising the following steps:

• preparing a laminated tube comprising an outer layer and an inner layer;
• setting the laminated tube in a mold composed of two halves, wherein one of the two halves has a cutting tool movably mounted thereon;
• clamping the two halves of the mold, and making the outer layer and the inner layer of the laminated tube compressed by bottoms of the two halves and joined;
• inserting a nozzle and injecting air into the laminated tube from a top end thereof, and pushing the laminated tube out to match the two halves of the mold to be shaped as a blow-molded lamination container;
• moving the cutting tool, cutting off residues of the outer layer and the inner layer, and engraving an opening with a triangular cross section on a bottom of the outer layer;
• and
• opening the mold, taking out the blow-molded lamination container, and generating an air-inletting seam from the opening with a triangular cross section;
• wherein the inner layer is not nipped within the air-inletting seam by the outer layer.
