Title: IMPROVEMENTS IN GAS STORAGE DEVICES
Abstract:
The invention relates to a device (10) for dispensing oxygen (30) under pressure. The device comprises a canister (12) filled with activated carbon (14) and oxygen (30) at a pressure of between 4 and 20 barg, when measured at room temperature. The canister is sealed with a valve assembly (18) allowing release of oxygen from the canister on actuation of the valve assembly. To ensure the activated carbon does not react with the oxygen generating carbon monoxide the device further comprises a catalyst (16) that prevents or significantly reduces the presence of carbon monoxide. In a further aspect there is a device (10) for dispensing a gas (30) under pressure which device comprises a canister (12) with a volume of 1 I or less filled with activated carbon (14) to adsorb the gas under a pressure of between 4 and 20 barg when measured at room temperature. The canister (12) is sealed with a valve assembly (18) crimped to the canister over a seal allowing release of the gas (30) from the canister on actuation of the valve assembly, wherein the gas is carbon dioxide, oxygen, nitrogen or air, and the canister is a steel canister. In a particularly favoured embodiment the device is filled with carbon dioxide and includes a high volume discharge valve making it useful as a pet behaviour correction device.
