Abstract: A plastic formed body having a pouring port 110 for pouring out highly wetting liquid that wets plastics to a high degree, wherein at least either a surface 110b that becomes a liquid-drip flow passage when said liquid drips at the pouring port 110 or a surface 110a that becomes a flow passage when said liquid is poured out, is coated with a fluorine-contained resin, and a surface of the fluorine-contained resin coating has an arithmetic mean roughness (Ra) in a range of 0.4 to 200 ?m in the surface roughness measurement and an element mean height (Rh) in a range of 0.04 to 10 as defined by mean height (Rc)/element mean length (RSm) in the linear roughness measurement. The formed body effectively prevents said highly wetting liquid from dripping at the pouring port 110.

Abstract: A compound container has a container main body forming a first accommodation chamber, an auxiliary container forming a second accommodation chamber, a mounting part on which the auxiliary container is mounted in the container main body, a cutting part which cuts a second accommodation chamber partition wall which partitions a part of the second accommodation chamber formed in the auxiliary container, a contents outlet port in the container main body, and an opening pouring element mounted on the contents outlet port and having another cutting part which cuts a first accommodation chamber partition wall which partitions a part of the first accommodation chamber formed in the container main body.

Abstract: A compound container which is comprised of a container main body 2 forming a first accommodation chamber 20 and an auxiliary container 3 forming a second accommodation chamber 30, wherein a mounting part 22 on which the auxiliary container 3 is mounted is provided in the container main body 2 and a cutting part 221 which cuts a second accommodation chamber partition wall 30a which partitions part of the second accommodation chamber 30 formed in the auxiliary container 3 is formed, and when the auxiliary container 3 is mounted on the container main body 2, the second accommodation chamber partition wall 30a is cut, whereby the first accommodation chamber 20 and the second accommodation chamber 30 are intercommunicated.

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).
