Title: Battery seal

Abstract

This patent describes a battery seal comprising a plug of air-tight material which fits within an open end of a battery jacket and which has a layer of sealant on at least one of its surfaces which face the interior of the battery. The battery jacket is comprised of a material having sufficiently elastic properties to cause the jacket to regain its original shape after slight distortion under a temporary pressure. The battery jacket is crimped, along its edge which forms the open end, in a manner which causes the jacket to directly or indirectly compress the plug inward onto a receiving member such that the receiving member contacts the plug, in the region of the sealant, at a pressure which is sufficient to provide an air-tight seal between the plug and receiving member under normal battery storage and operating conditions yet is low enough to allow the plug to move sufficiently away from the receiving member in response to force exerted on the plug by abnormal gas pressure within the battery to vent the gas. The plug reseats on the receiving member after the gas is vented to re-form an air-tight seal.
