International ClassesB65D 081/24B65D 085/30 B65B 029/00 AbstractA package for storing one or more batteries comprising a container defining an encapsulated hollow region and having walls that provide a first vapor permeability. The package contains an air cell or air-assisted cell battery housed within the container. Also housed within the container is a vapor control medium for providing controlled vapor flooding within the container so as to substantially match the vapor pressure of the hollow region with the vapor pressure within the air cell battery. The package allows for an electrically-operated device to be assembled with the air cell battery and housed ready for use within the package, while advantageously controlling the vapor pressure to minimize cell performance degradation.Field of SearchFor a batteryButton battery (e.g., watch battery) Dry cell WITH MOISTURE ABSORBENT FOR A HOUSEHOLD APPLIANCE ARTICLE HOUSING ATTACHED TO PANEL Housing contoured to retain article With adsorption or absorption of contents PRESERVING CELL IN STORAGE FEATURE SEALED CELL HAVING GAS PREVENTION OR ELIMATION MEANS Cell with protective layer on electrolyte | |
