Abstract: A cap device or fuel cap has a cap main body, a cover, and a torque plate that transmits a rotational torque. The torque plate is attached to the cap main body in a rotatable manner through engagement of catching claws formed on the outer circumference of the torque plate with catching projections formed on the cap main body. The cover is held on the torque plate in a rotatable manner through engagement of engagement projections formed on the inner wall of the cover with catching claws formed on respective fixation elements. The engagement projections are arranged about an axis of the cap main body and outside the catching claws. The engagement projections are thus readily released from engagement with the catching claws under application of an external force in any of diverse directions, for example, due to a collision of a vehicle, so as to maintain the sufficient sealing properties of the cap main body.

Abstract: An externally threaded closure plug for tightly closing off the internally threaded opening in shipping and storage containers such as drums, pails and the like. The plug is formed as a cup having a bottom wall and threaded cylindrical sidewall terminating in a circumferentially enlarged rim. Immediately beneath the rim of the plug is a gasket seat defined by the undersurface of the plug rim, the plug sidewall and an annular gasket retaining lip lying in a plane parallel to the undersurface of the plug rim. In use, the plug is screwed into and out of a container wall opening, having an internally threaded portion and an unthreaded portion, the sealing gasket being compressed between the unthreaded opening portion and the plug gasket seat and lying in close proximity to the internal thread. The gasket seat acts to prevent interengagement of the sealing gasket and the opening internally threaded portion.

Abstract: A fuel cap has a torque member attached to an upper portion of a casing body. The torque member is a disk-shaped plate to transmit a rotational torque applied to a handle to the casing body. An interlocking recess and interlocking claws, which constitute a plate attachment mechanism, are arranged on the upper portion of the casing member. Fitting of the interlocking claws in the interlocking recess causes the torque member to be attached to the casing body in a freely rotatable manner. This simple structure of the invention effectively prevents the fuel cap from being easily damaged by an inadvertent operation, such as a careless drop of the fuel cap, and ensures the sufficient sealing properties of the fuel cap even under application of an external load.

Abstract: A vent insert with an integral carbon-to-carbon composite filter element is used to vent enclosures such as drums and convenience cans containing transuranic materials which generate hydrogen. The vent inserts do not utilize adhesive to retain filter elements therein but rather utilize a housing having a filter element support with a knife edge to form a seal and a press fitted lid. Both the housing and lid are formed of corrosion resistant HASTELLOY® C-22® alloy. The vent inserts resist HCl corrosion as well as corrosion induced by nitric acid and chlorinated solvents.

Abstract: A steel-body vessel, suitable for storing ultra-high purity gases, has a relatively inert metal lining which covers the interior surface of the steel vessel body, preventing the stored gas from making any contact and reacting with the steel vessel body. The relatively inert metal lining extends into the vessel end pieces which are interiorly threaded, in the steel, proximate the relatively inert metal lining. The surface of the inert metal lining is conditioned to be smooth, preferably to 15 ?Ra or better. The vessel end pieces are sealed with end closure devices, which are secured by a securing portion carrying exterior threads to matingly engage the interior threads on the vessel end pieces. The end closure devices contain a sealing portion constructed of the relatively inert metal, which retains an annular sealing gland to seal the vessel in a removable, non-contaminating manner at service pressures when the end closure device is seated within the vessel end piece by means of the securing portion.

Abstract: A fuel cap has a torque member that is attached to a casing body in a freely rotatable manner. A tether mechanism is attached to the torque member and functions to link the fuel cap with a fuel lid. The tether mechanism includes a tether rotation support that is set on the torque member in a freely rotatable manner, and a connector member. The torque member is mainly composed of a resin material, for example, polyacetal, whereas the tether rotation support is mainly composed of a thermoplastic elastomer (TPEE). The resin material of the torque member has a liquid swelling property substantially equal to or less than that of the tether rotation support. This structure of the invention ensures the good operation ability of the fuel cap even in wet weather.

The over cap is screwed to an outer wall of a tubular spout (6) that surrounds the neck (10) of the bottle. In the resealed condition the plug can be screwed deeper into the neck so that a secondary seal is formed between the plate and the neck.

Abstract: A fuel cap is equipped with the torque mechanism 80. The torque mechanism 80 comprises the handle engagement element 46a formed on the cover 40; the torque plate 90, having the torque piece engagement element 94b; and a spring. When the cover 40 is rotated in the closing direction, the handle engagement element 46a disengages from torque piece engagement element 94b and the engagement gives the user a feeling of attachment by an audible click. At that time, elastic torque piece 94 elastically deforms so that the handle engagement vertical surface 46b is pushed in the radial direction by the engaging vertical surface 94d, a slot 94c. Conversely, when the cap is rotated in the opening direction, the engaging inclined surface 46c pushes the engaging inclined surface 94e and elastic torque piece 94 inclines with the support end 94a, and thus the cap transitions to a non-engaged state, and the cover 40 is returned to an initial position relative to the casing main body 20.
