Abstract
An improved vent cap system for use in an electrochemical battery is provided which includes a ring flange for forming a ring seal between the vent cap assembly and the fill tube. When the vent cap assembly is positioned in the battery housing, the ring flange and the fill tube deform to create a seal therebetween to provide a fluid tight seal.
Claims27
A vent cap assembly for a battery comprising an electrolyte, the vent cap assembly comprising:
- a top portion;
- a vent cylinder extending downwardly from said top portion and arranged to be inserted into a fill tube of a battery housing;
- a ring flange formed on an outer wall of said vent cylinder having a radial thickness formed on said vent cylinder;
- and
- said vent cylinder insertable within the fill tube such that said ring flange deforms the fill tube to create a ring seal between said vent cylinder and the fill tube.

A vent cap assembly for a battery comprising an electrolyte, the vent cap assembly comprising:
- a top portion;
- a vent cylinder extending downwardly from said top portion and arranged to be inserted into a fill tube of a battery housing;
- a ring flange formed on an outer wall of said vent cylinder having a radial thickness formed on said vent cylinder, wherein said ring flange comprises:
- a trailing portion formed on a first end of ring flange adjacent said top portion;
- and
- a leading portion formed on an end of said ring flange opposite said first end thereof, said leading portion and said trailing portion intersecting to form an apex;
- and
- said vent cylinder insertable within the fill tube such that said ring flange deforms the fill tube to create a ring seal between said vent cylinder and the fill tube.

A vent cap assembly for a battery comprising an electrolyte, the vent cap assembly comprising:
- a top portion;
- a vent cylinder extending downwardly from said top portion and arranged to be inserted into a fill tube of a battery housing wherein said top portion comprises an upper component and a lower component fitted in abutting relationship to define an interior volume therebetween, said vent cylinder extending from a floor portion of said lower component;
- a ring flange formed on an outer wall of said vent cylinder having a radial thickness formed on said vent cylinder, and
- said vent cylinder insertable within the fill tube such that said ring flange deforms the fill tube to create a ring seal between said vent cylinder and the fill tube.

A vent cap assembly for a battery comprising an electrolyte, the vent cap assembly comprising:
- a top portion having an upper component and a lower component fitted in abutting relationship to define an interior volume therebetween, a vent passageway formed though said top portion to provide fluid communication between said interior volume and an environment outside said vent cap assembly, a splash guard extending downwardly from said upper component into said interior volume, and a floor including a horizontal portion and an inclined portion formed in said lower component;
- a flame arrestor operably disposed in said vent passageway;
- a vent cylinder extending downwardly from said horizontal portion of said floor and arranged to be inserted into a fill tube of a battery housing, said vent cylinder having an outer wall, a retaining flange formed on said outer wall and a breather slot formed therethrough;
- a ring flange formed on said outer wall of said vent cylinder and including a trailing portion having an angular orientation of approximately one hundred and five degrees with respect to said outer wall of said vent cylinder formed at a first end of ring flange adjacent said top portion, a leading portion having an angular orientation of approximately thirty degrees with respect to said outer wall of said vent cylinder formed on an end of said ring flange opposite said first end thereof, and a rounded apex formed at an intersection of said leading and trailing portions, said vent cylinder insertable within the fill tube such that said ring flange and the fill tube deform to create a ring seal therebetween.
