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 cc 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 00 gas under a pressure of between 4 and 20 barg when measured at room temperature. The canister (12) is sealed with a valve assembly O (18) crimped to the canister over a seal allowing release of the gas (30) from the canister on actuation of the valve assembly, wherein C [Continued on next page] WO 2018/158553 Al MIDEDIMOMOIDEIREEMOMMEMBIONOINDEVOIS SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW. (84) Designated States (unless otherwise indicated, for every kind of regional protection available): ARIPO (BW, GH, GM, KE, LR, LS, MW, MZ, NA, RW, SD, SL, ST, SZ, TZ, UG, ZM, ZW), Eurasian (AM, AZ, BY, KG, KZ, RU, TJ, TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG). Declarations under Rule 4.17: as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(11)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(iii)) Published: with international search report (Art. 21(3)) before the expiration of the time limit for amending the claims and to be republished in the event of receipt of amendments (Rule 48.2(h)) 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.
