Abstract: A removable cap for closing the filler neck of a fuel tank for an internal combustion engine. The cap includes a one piece gasket and baffle member which not only provides a fluid seal between the cap and the filler neck, but also permits venting of the fuel tank through the gasket. The one piece member includes an annular flat gasket portion integrally formed on the outer periphery of a dome-shaped baffle member projecting downwardly from the inner surface of the cap. Venting is accomplished by means of at least one vent opening extending through the dome-shaped baffle member which in turn communicates via a vent chamber to a passageway formed through the gasket. The passageway in turn communicates with a non-sealing threaded interconnection between the cap and filler neck. A splash guard is also located beneath the baffle member to aid in preventing fuel from splashing through the vent openings in the baffle member.

Abstract: Packaging for coffee which is to be packed as quickly as is feasible after roasting, i.e., without undergoing substantial off gassing. The packaging preferably comprises a semi-rigid, substantially gas-impervious container capable of withstanding the pressures generated by the release of carbon dioxide and other gases from the fresh roasted coffee in the container. The semi-rigid container is preferably comprised of plastic and predetermined portions of the container are preferably capable of undergoing limited deformation. This prevents instability of the base of the container, thereby keeping its vertical axis erect, and ensures that the container does not become jammed within the shipping case in which it is transported due to lateral expansion.

Abstract: A breather vent mountable on the vent pipe outlet from an underground storage tank at a gasoline service station site. A vent housing includes a body section adapted for placement on the vent pipe and which cooperates with a superposed cap section to accommodate a vapor floatable valve disc supported internally thereof. Vapors from the tank can normally discharge in a primary flow path past the valve disc from where it is diverted upwardly by an annular diverging deflector to atmosphere. Displaced apertures having comparatively increased protection against freezeup form an alternative outlet for a secondary flow path diverted downwardly from a location downstream of the valve disc. The latter being better protected against freezing rain, etc. enables continued vent discharge to atmosphere in the event the primary flow path becomes ice blocked.
