A recess 32a is formed in the foremost end portion of an insertion portion of a plug P10. A lubricating film 72 is provided as lubricating property imparting means 70 for imparting lubricating property to at least one of contact seal surfaces A formed by fitting and coupling of a socket S10 and the plug P10. Lubricating property is imparted to the contact seal surface A formed by fitting and coupling of the socket S10 and the plug P10 by the lubricating film 72 of the lubricating property imparting means 70 to thereby achieve smooth coupling and secure sealing property by close fitting of the socket S10 with the plug P10.

This invention provides an elastic member for a methanol fuel cell cartridge, comprising an elastomer having a compression set of 1 to 80 and a hardness (type A) of 40 to 70 and having an operating limit time of 10,000 hours or more determined by a DMFC performance test for the fuel cell. The elastic member can prevent leakage of methanol from a methanol fuel cell cartridge, or a connection part between the cartridge and a fuel cell body and, at the same time, can realize long-term operation of the fuel cell without causing deterioration of power generation performance.

A fuel bottle 10 for a fuel cell having a bottle main body 12 for containing fuel for a fuel cell and comprising a nozzle portion 11 at the tip portion of the bottle main body 12 on which a coupler for connecting with a main body of a fuel cell can be attached and a trunk portion having a generally elliptic shape in cross section and having been formed by blow molding. In this bottle 10, length L1 in one direction of minor axis from the center On of the nozzle portion of the elliptic shape in cross section differs from length L2 in the other direction of the minor axis from the center On of the nozzle portion. By this structure, a moving space of a push button when the fuel bottle 10 is housed in a hard case can be secured while necessary capacity of the fuel bottle 10 is secured. Pinch portions 13 and 14 are formed in lowly stretched portions of the bottle main body 12 in a manner to protrude outwardly whereby contact areas of the pinch portions 13 and 14 are increased and contact strength thereby is improved.

There are provided a screw-type cap which can secure necessary fastening torque (opening torque) even in a case of a container having a plug having a foremost end portion of a small diameter and also a safety cap which cannot be opened by only rotation and therefore has a child resistance effect. A safety cap 20 consists of a screw-type inner cap 21 and an outer cap 22 which is mounted in such a manner that it covers the inner cap 21 and can be rotated and can displace axially within a limited distance. The outer cap 22 can rotate integrally with the inner cap 21 by pushing down the outer cap 22 and rotate it while the outer cap 22 rotates idly by rotation only. A plug portion 8 is formed by projecting a plug 6 from a disk portion 7 which is in abutting engagement with a tip end portion of a mouth portion 2 of the container. The inner cap 21 has a small diameter portion 21c formed in the inner middle portion thereof. The small diameter portion 21c is in abutting engagement with the disk portion 7 and controls interference by screwing. By causing the small diameter portion 21c of the inner cap 21 against the disk portion 7 of the plug 6, interference can be controlled to prevent excessive fastening and necessary fastening torque (opening torque) can be secured even in a case where the cap has the plug portion having a small diameter while idle rotation can be secured to achieve a child resistance effect.

A couple 10 includes a valve seal member 71 (36) provided in a flow path between a valve 35 and a coupler main body 31 which can be opened and closed, and a container-inside-outside seal member (73) which is used as both a container seal member (73) for forming a seal between the container main body 31 and a valve holder 38 and a holder seal member (73) for forming a seal between the coupler main body 31 and the valve holder 38. By this arrangement, the number of the seal members can be reduced, processes for assembling can be simplified and the manufacturing cost can be saved. Mounting position of the holder 38 can be controlled by a mounting position control section 74 to enable sealing for maintaining energizing force by energizing means 39 constant and ensuring opening of the coupler as well as for securing the sealed state accurately.

A coupler 10 comprises a socket S10 comprising a valve 16 and a metal helical spring 17 for energizing the valve in a closing direction and a plug comprising a valve 24 and a metal helical spring 25 for energizing the valve in a closing direction and being capable of being detachably fitted and coupled to the socket and being capable of opening the two valves to communicate the socket and the plug to each other in a fitted and coupled state. Elastic member holders 18 and 26 are mounted at an base end portion of the valves 16 and 25 in a sealable manner and in such a manner that the valves can reciprocate in closing and opening directions, said elastic member holders housing the energizing means for energizing the valves and flow paths being formed outside of the elastic member holders. By this arrangement, by housing the metal helical springs in the elastic member holders, contact between the metal helical springs and liquid can be prevented.
