摘要:
An alkaline cell having a flat housing, preferably of cuboid shape. The housing may be laser welded closed with a metal cover inserted as a part of an end cap assembly. A portion of an insulating seal may be held compressed between a sleeve extending from the metal cover and an anode current collector nail within the end cap assembly. The housing may include a vent mechanism, preferably a grooved vent, which can activate, when gas pressure within the cell reaches a threshold level typically between about 250 and 800 psig (1724null103 and 5515null103 pascal gage). The cell can have a supplemental laser welded vent which may activate at higher pressure levels.

A cookware lid has upper and lower holes provided on a recessed, sloping surface. The lower end of the recessed surface provides a reservoir to receive and drain liquid The upper holes allow steam and foam to escape a vessel, condense and run down the sloping surface into the reservoir and back into a vessel, avoiding boil over during cooking. The lid may also include a locking mechanism to attach to a vessel so as to further avoid boil over and also permit straining.

A venting device for a drum. The venting device includes a body having a pair of opposing sides and defining a plurality of vent passages. The vent passages extend through the body and each an opening at each of the pair of opposing sides. The vent passages are spaced apart and arranged around a center portion of the body. A membrane structure is positioned so as to cover the openings of the vent passages on one of the pair of opposing sides of the body. The membrane structure is sealingly affixed to the body portion in an outer sealing band surrounding the openings of the vent passages. The membrane structure may be further affixed with one or more cross sealing bands extending across the membrane. A portion of the membrane structure may be further affixed to the center portion of the body. A protective structure may be attached to the body and positioned over the membrane structure.

There is described a neck structure in combination with a closure. The neck structure defines a neck opening with a cylindrical sealing surface surrounding the neck opening and an external neck surface. The closure comprises a cap formed of resilient material having a top and a downwardly extending skirt portion depending from the top. An annular plug depends from an underside of the top and one or more ribs are formed on an internal surface of the downwardly extending skirt portion. The annular plug and the one or more ribs are arranged concentrically and are dimensioned such that, upon application of the cap to the neck structure, the annular plug projects into the neck opening and engages the cylindrical sealing surface. At the same time the one or more ribs engage the external neck surface. The annular plug is adapted to flex away from the cylindrical sealing surface upon the build up of excess pressure within the closure whereupon circumferentially spaced ends of the or each rib define therebetween a path for the venting of fluid to release the excess pressure. There is also described a closure for use with a neck structure.
摘要:
A fuel cap 10 maintains high sealing even when subjected to external force; is easy to operate; and requires minimal space for accommodation. The cap device comprises a casing body 20 for closing the filler opening FNb in a sealed condition, a cover 40, a handle 45, a clutch mechanism 60 and a torque transmission mechanism 80. By upraising the handle to the handling position and applying rotational torque, rotational torque is transmitted to the casing body 20 via the clutch mechanism 60 and the torque transmission mechanism 80, closing the filler opening FNb. The handle 45 lowers back to the retracted position when released, whereupon the clutch mechanism 60 assumes non-transmission mode wherein the cover 40 and the handle 45 rotate freely if subjected to external force such as in a collision.

A safety valve apparatus is arranged on a water inlet of a vapor heater and comprises a cover, a clutch unit and a resilient unit. The clutch unit comprises an upper disk and a stage detachably assembled with the upper disk. The resilient unit is arranged between the cover and the upper disk such that the upper disk is normally rotated with the cover. The upper disk has a downward extending cylinder looped by a spring and having a movable cap on one distal end thereof. The movable cap normally seals an outlet below the stage by the resilient force of the spring.

A tank cap for closing a filler neck of a fuel tank for a motor vehicle with a pot-shaped inner closure body, includes a lower pot body and an upper supporting flange, supporting itself on the upper edge of the filler neck and extending outward at a right angle from the pot body, and a cap body, which is placed on the closure body, whereby the tank cap can be loosened from the filler neck by turning the closure body around a rotational axis and ambient air is able to enter through at least one air inlet in the tank cap in the connection piece, circumventing a connection piece seal against a reflux seal.

A kind of sealing valve for vacuum container comprising: the cap body, the connecting body and the locking portion; the cap body is to be jointed to the locking portion through the connecting body; the locking portion is formed with the concave portion; the locking portion is to lock onto the hole on the upper cap via the concave portion, thus when the vacuum pump proceeds to extract air out of the vacuum container, the cap body is to be deflected and deformed by air flow, so that the air hole of the upper cap is to be opened, and then the cap body is to automatically close the air hole of the upper cap after the pressure difference between the interior and exterior of the vacuum container has reached the predetermined value.

An air vent plug for clean container is disclosed, which includes a mounting ring, a plug body, and a plug cap, the plug cap having an inner ring fitted into the plug body, retaining notches forced into engagement with respective hooks of the plug body, an outer ring fitted over the outer surface of the mounting ring, and top hooks extended from the outer ring and hooked on respective pegs at the outer surface of the mounting ring. An O-ring is mounted outside the plug body and stopped between a collar of the plug body and a bottom edge of the mounting ring for sealing. A filter is mounted inside the plug body to prevent contamination from air passing through the plug body and the air vent of the clean container.
