B LID FOR AEROSOL CONTAINER; AEROSOL CONTAINER; METHOD FOR MANUFACTURING AN AEROSOL CONTAINER; COVER DEFORMATION METHOD OF AN AEROSOL CONTAINER; METHOD FOR FORMING A LID FOR AN AEROSOL CONTAINER AND APPLIANCE FOR UNITING AN AEROSOL D CONTAINER LID. An aerosol canister lid having a central opening for a nozzle and an outer edge adapted for sealing union to the open end of an aerosol canister body. The lid of the aerosol container being of relatively thin-walled metal and having a wall thickness ranging from 0.005 to 0.013 inch (0.127 to 0.330 mm) if the metal is steel; and 0.005 to 0.018 inch (0.127 to 0.457 mm) thick, if the metal is aluminum. The lid has a thinner wall than it would be to prevent deformation or eversion at minimum pressure levels in the aerosol container stipulated by the government. The cover is generally convex in shape as it extends from its outer edge to the central opening, and does not contain any countersunk recesses in the vicinity of its outer edge. In a method of manufacturing the aerosol container lid, the lid is attached to the container body by conventional sewing process. The cover, in its initial stage, has a countersunk recess in the vicinity of its outer edge, which is used in the sewing process to accommodate a sewing turning. After that, the countersunk recess is everted by pressurization. In a method of sewing the thin-walled lid of the present invention with an aerosol container body, the lid, which does not contain a countersunk recess, is placed over the open end of a container body. One or more stretchable arms are positioned on the body of the container to oppose the sewing cylinders and, thus, join the lid with the body of the container.
