ABSTRACT:
The cover for a breathing apparatus canister has a body portion of substantially the same shape as the top of the canister and is provided with a skirt extending around the upper part of the canister and also with a central opening through which the neck of the canister extends. Extending from the body portion upwardly around the neck is a circular side wall closed at its upper end by a top wall above the sealing ring that encircles the upper end of the neck. The side wall is provided with inwardly projecting detents underlying the sealing ring to hold the cover in place, but the detents are sufficiently yieldable to permit the cover to be applied to the canister and removed.
