Abstract: The present invention is a container multilayered body (1, 2) that is used to form a container, having an innermost layer (3) made of a cyclic polyolefin, an intermediate layer (4) that is formed so as to be adjacent to the innermost layer (3) and contains a linear low-density polyethylene produced using a single-site catalyst as a main component, and an outer layer (5) made of one of a random polypropylene produced using a single-site catalyst or a polypropylene containing an elastomer.

Abstract: The spout cap of the present invention includes: a cap body that tubularly surrounds a mouth portion of a spout body, and is an injection molded article made of resin; and a sealing film that is bonded to one side in a penetration direction of the cap body and can be thermally bonded to a tip surface of the mouth portion. The cap body includes a tubular body portion, and a tab portion disposed outside in a caliber direction with respect to the body portion. The tab portion includes a tab base portion that projects outward in the caliber direction from the other side in the penetration direction of the body portion, and a tab body portion that extends from the tab base portion toward the one side in the penetration direction and faces the body portion on an outside in the caliber direction.

Abstract: A multilayer film (10) for a container includes a surface layer (11) made of a polymethylpentene resin, an adhesive layer (12) made of a thermoplastic elastomer and adjacent to the surface layer, and a heat seal layer (13) laminated on the surface layer through the adhesive layer.

Abstract: A spout cap is a spout cap for closing a mouth portion of a spout main body, and includes a cylindrical body portion made of resin, and a sealing film joined to the body portion, in which the sealing film has a thermal bonding layer which is configured to join to a distal end surface of the mouth portion when the mouth portion is closed.
