A locking aerosol dispenser with a dome, a top thermoplastic elastomeric button member molded over a dome opening, and a base lock member. The rotatable base lock rotates from locked to unlocked position with respect to the essentially non-rotatable dome. A product channel member in the dome is held by the elastomeric button, and not otherwise attached to the dome. The base lock has an upstanding bridge with unlocking slots within which extend fingers on the product channel member when the dispenser is unlocked and actuated. The base lock is not attached to the aerosol valve mounting cup. The dome is attached to the base lock member and the aerosol valve mounting cup, the dome capturing the base lock member between the dome and aerosol container.

Locking aerosol dispenser

Aerosol dispenser for a pressurized container

An improved gasketed mounting cup for an aerosol container wherein the mounting cup has a curvilinear channel portion and the gasket is a folded-over sleeve gasket, simulating the gasket thickness of a cut gasket; wherein the outer segment of the folded-over gasket is longer than the other gasket segment but of a limited length that will allow the ultimate positioning of the gasket without the longer gasket segment contacting the surface of the mounting cup and being wedged between the bead of the container and the mounting cup during advancement of the gasket into the mounting cup.

Gasketed aerosol mounting cup

An apparatus for forming a double-segment overlapping gasket material for the mounting cup of an aerosol container comprising a punch mounted on a reciprocating ram having a central opening for the body of the mounting cup and a nose portion adapted to extend within the channel portion of the mounting cup, said nose portion having a specific shape and the punch having a shoulder in the inside diameter of the punch to urge the gasket material disposed on the body portion of the cup into the channel portion, whereat upon the bottoming of the punch against the gasket, a fold line is formed in the gasket which results in the formation of the overlapping double-segment gasket.

Apparatus for an improved gasketed aerosol mounting cup

A multi-layer gasket for providing a seal between a mounting cup and a container comprising a middle layer of rigid plastic material and inner and outer layers of softer plastic material. The middle layer supports the inner and outer layers, which provide sealing surfaces with the mounting cup and the container bead. A gasketed mounting cup comprising a panel, a skirt integral with and depending from the periphery of the panel, wherein the skirt is outwardly flared to form an annular channel for receiving a container bead that defines the container opening and a multi-layer gasket positioned in the channel portion of the mounting cup, which gasket comprises a middle layer of rigid plastic material, an inner layer of soft plastic material adjacent the channel of the mounting cup and an outer layer of soft plastic material for engaging the container bead. The middle layer is preferably high density polyethylene or polypropylene and the inner and outer layers are preferably linear low density polyethylene. A layer of thermally activated adhesive can be placed adjacent the inner layer.
