Abstract: A container of a multilayered structure comprising an inner layer and an outer layer of a low-density polyethylene, and an intermediate layer that includes a gas-barrier resin layer and adhesive layers, wherein the adhesive layers contain an acid-modified polyethylene and a propylene resin, the propylene resin being contained in an amount of 0.5 to 10% by weight in the adhesive layers. The container is obtained by using decreased amounts of resins without impairing properties of the containers.

Abstract: When extrusion molding is conducted continuously for a long period of time, in order to prevent a die drool from being generated at an outlet of an extruder, to a shell 2 in which an outlet 3, through which a melt-kneaded resin material is extruded by an extruder, is formed, a plate-like shell tip 6 in which an opening 7 which is arranged such that it surrounds the outlet 3 along the circumference thereof is detachably attached, and non-sticky coating is applied at least along the outer surface of the core tip.

Abstract: Liquid fuel received in a container can be injected manually in a safe, easy and convenient manner. In a fuel cell cartridge for fuel cells in which at a port portion (14) of the container (10) in which the liquid fuel is received, there is provided a plug (30P) that is adapted to be connected with a fuel cell for filling the fuel thereinto, a bellows portion (15) acting as a portion capable of extension and contraction is formed in at least a part of the container (10), and on the plug (30P), there is provided a valve mechanism (34) which is held in a normally closed state in a free state thereof, and is opened when the plug is connected with the fuel cell (70).
