Abstract: Disclosed is an aerosol actuator button for delivering a product such as an atomized air freshener liquid from a pressurized aerosol container wherein the spray pattern produced is tilted away from the central long axis of the actuator button and container. Tilting of the spray pattern is accomplished by placing the actuator button orifice at the bottom of an asymmetrical conical depression which is open to the surrounding atmosphere. More preferably, the orifice itself is asymmetrical with the shorter portion of the orifice being situated relative to the conical depression such that tilting of the spray is accentuated. This configuration causes the atomized spray to be tilted away from the central long axis in spite of the fact that the orifice is concentric with the central long axis of the actuator button. Also disclosed are dies for making such actuator buttons.

Abstract: An injection-molded piston for an aerosol container has a face portion for contacting and exerting pressure on material to be dispensed, and a thin, flexible skirt depending axially from and circumscribing the face portion for forming an effective seal against the inside wall of the container. The outer wall of the skirt is continuous, while the circumference of the inner wall has alternating areas of constant thickness along said areas and areas of minimum thickness, the curved portions forming with the outer wall a plurality of sections, the thickness and circumferential extent of each of which decrease axially along the skirt toward its distal end. The piston includes a depending extension on the skirt which aids sealing.

Abstract: A valve actuator for use with an aerosol container comprises a cap mountable on the discharge end of the container and having an operating member movable to effect opening of a normally closed valve carried by the container and an actuator device arranged for movement relative to the cap and having a surface for engaging the operating member as the actuator device is moved from a first position to a second position so that the operating member remains in valve opening position so long as the actuator device is in the second position. A trigger is provided on the actuator device or the operating member for controlling the operating member when the actuator means is in the first position.

Abstract: An improved method for forming closed burstable pouches having breakable seals. The method includes selection of a laminated polymeric film which has two principal layers--an outer layer which is responsive, and an inner layer which is non-responsive, to a radio-frequency (RF) welding field, the inner layer being of a biaxially-oriented polymeric material such that its cohesive strength in its thickness direction is less than the cohesive strength of the outer layer. The outer layer has a higher melting point than the inner layer. With two sheets of such material placed with their inner surfaces in contact, the breakable seal is formed by applying an RF welding field for a time and at an intensity to heat the outer layers sufficiently to fuse the inner layers by heat transfer from the outer layers without melting the outer layers and without destroying the biaxially-oriented structure of the inner layer.

Abstract: A device for dispensing air-treating vapors having two support members between which is a flexible, generally flat dispensing pouch. The pouch has an inner storage container of an air-treating composition which is burstable by applying sandwiching pressure on the dispensing pouch through the support members to release the composition for dispensing. The support members have facing, substantially parallel apertured support surfaces which engage the pouch and are relatively movable between a first spacing in which the storage container is protected from bursting and a second spacing allowing bursting of the pouch. A spacer interconnecting one pair of aligned edges of the support members may be removed to allow bursting, and the aligned edges preferably thereafter reconnected at a closer spacing to hold the released composition in contact with much of the inner surface of the dispensing pouch.
