This relates to an improved aerosol container of the type wherein the dome is formed separately from the body and is secured to the body by a conventional double seam. The aerosol container is improved by squeezing the double seam radially inwardly so that it is, in effect, necked in and may also be tilted to correspond generally to the dome profile. In the ultimate condition the upper part of the body is also tilted radially inwardly and the chuck wall upper portion contacts the dome above the annular countersink completely to close the countersink. The container need not be an aerosol container, but may beneficially have not only the double seam joining the top end to the body radially inwardly offset or necked-in, but also if the bottom of the container is separately formed from the body, the double seam joining the bottom to the body should also be radially inwardly offset or necked-in so that bodies of adjacent containers may be in touching relation, thus requiring less material for a container and at the same time assuring a tight package. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

An aerosol container of the type which in use is internally pressurized and includes a body having an open top closed by an aerosol dome secured to said body by a double seam having an originally formed position and a final position, and wherein said dome has as part of said double seam a chuck wall surrounding an annular countersink for receiving a seaming chuck, said aerosol container being improved by said double seam being reduced in diameter from said originally formed position to overlie said annular countersink in said final position, said body immediately adjacent to and below said double seam being also deformed radially inwardly with said double seam being in its entirety recessed within the outline of said body.
