Abstract
Abstract An aerosol dome having a lower end adapted to be attached to a container and an upper end having an opening surrounded by an outwardly turned wall. The outwardly turned wall has a free end portion in overlapping and contacting engagement with an outer surface of the dome to define an enclosed area of uniform crosssectional configuration. The integral outwardly turned wall has openings defined therein with at least a portion of each of the openings being spaced from the free end portion and the adjacent outer surface of the dome to place the enclosed area in communication with the surrounding atmosphere. In one embodiment the opening is produced by forming a recess extending from the free edge through the free end portion with the base of the recess being spaced from the adjacent outer surface of the dome. In an alternative embodiment the opening is defined by an aperture extending through the wall at a point spaced from the free end.

Claim 1
Independent Claim
167 words
In an aerosol dome of the type having a dome body portion attached to a container and with a wall terminating in a free edge and an upper end with an opening defined by a vented curl formed by an outwardly turned portion of said wall, said curl defining a closed internal area, and a mounting cup within said opening and having a bead surrounding and crimped to the major external portion of said curl, the improvement in said curl comprising: a segment of said outwardly turned portion adjacent said free edge being in overlapping engagement with and in a plane parallel to an adjacent outer surface of said dome body portion; said closed internal area having a uniform crosssectional configuration throughout its circumferential length; an opening means extending through said outwardly turned portion in an area between said overlapping portion and said major portion of said curl to which said mounting cup is crimped, for venting and draining said closed internal area to the surrounding atmosphere.
Claim 2
Dependent Claim
