A plastic formed body having a pouring portfor pouring out highly wetting liquid that wets plastics to a high degree, wherein at least either a surfacethat becomes a liquid-drip flow passage when said liquid drips at the pouring portor a surfacethat 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 &#x3bc;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

Coupling holding meanscomprising retainersand retainer engaging portionsfor holding a coupled state is provided between a socket Sand a plug Pof a coupler. Engaging pawl portionsare formed on the inner sides of a pair of retainersprovided on both sides of a nozzle portion. By causing the retainersto move outwardly in a coupling operation, a gap between the retainersand the nozzle portioncan be made small. By forming interference preventing portionsin the engaging pawl portions, the retainerscan be provided at a smaller interval than the outer diameter of the nozzle portionwhereby the coupler can be made even more compact. Further, by forming the retainershigher than the foremost end portion of the nozzle portion, the nozzle portioncan be protected by the retainerseven in an unexpected event such as falling and damage will not extend directly to the nozzle portion

Coupler

A coupler having a socket with a valve and an element for energizing the valve in a closing direction, and a plug having a valve and an element for energizing the valve of the plug in a closing direction, where the plug is detachably fitted and coupled with the socket and is capable of communicating with the socket by opening the valve of the plug and the valve of the socket in the fitted and coupled state, A key groove or a key is provided in either the socket or the plug, and a ring member having a key or a key groove which can be fitted with the key groove or the key is provided in the other of the socket and the plug and the ring member is rotatable about a central axis of connection of the socket and the plug.

Coupler for transferring a liquid or other material between containers

In, for example, a direct methanol type fuelcell, fuel is allowed to be injected little by little when the fuel is injected and supplied from the outside to a fuel receiving part reduced in the amount of remaining fuel on the fuelcell body side and an electromotive part can be prevented from being damaged by keeping the pressure in the fuel receiving part at a fixed level or less when the fuel is injected. Specifically, when a fuel CL filled in a refuelling container C is injected into a fuel receiving part T in several lots, a fuel injecting operation is repeated in which the volume of the refuelling container C is shrunk and reduced to supply the fuel into the fuel receiving part T in a proper amount and then the original volume of the refuelling container is restored to thereby absorb the atmospheric gas in the fuel receiving part T, which makes it possible to inject fuel continuously without any hindrance to the injection of the fuel.

A stainless steel material for a fuel cell, used for a fuel cell or a cartridge for the fuel cell, having a magnetic permeability of 1.000 to 2.500, and forming a layer having a value of chromium atomic %/iron atomic % of not less than 3.0 in the most surface thereof, and/or the layer of thickness of not less than 12 nm calculated as SiOhaving an oxygen atomic % of not less than 20%. Even when brought into contact with the content solution exhibiting acidity of the fuel cell, the stainless steel material reliably suppresses the elution of metal ions thereof.

Stainless steel member for a fuel cell

A bag-like container with a spout in which a plastic linear fastener is interposed in an upper part of the container so that when water content or the like is to be supplied after contents of a liquid food container or the like have been administered to a subject, opening and closing the linear fastener enables the water content or the like to be supplied in an uncomplicated manner without the use of a separate member such as a spout that is an open part for pouring food, water, or the like into the container.
