Abstract:
A valve for a pressurized dispensing container has one or two dispensing openings through the wall of the valve stem. A dispensing nozzle with an actuating handle has a predetermined alignment with the opening or openings in the valve stem so that actuation of the nozzle will assure that one and only one full opening is presented to the product during dispensing. This keeps the leg or wall area between openings out of the path of the product being dispensed and avoids the build up of fiber that tends to clog the opening. A small retaining wall between the valve seat.at the bottom of the valve stem and the lower edge of the opening or openings provides a wall that prevents the flexible rubber-like seal from being distorted under pressure and setting in a position where it blocks the opening when product is to be dispensed. Each of the dispensing openings in the two opening embodiment extends at least 90° around the valve stem and the single opening embodiment may extend as much as 180°.
Abstract:
A dispensing mechanism for a pressurized container employs a platform which sits on and engages the valve cap. A lever pivoted on the platform extends from its pivot point up and around the nozzle to terminate in the handle that is adjacent to the sidewall of the pressurized container. The upper portion of the lever engages the shoulder on the nozzle so that when the handle is manually squeezed against the sidewall of the container, the lever pushes down on the nozzle thus pushing the nozzle and valve in a downward axially direction thereby dispensing the pressurized contents of the container. It is when the nozzle is screwed into a dispensing state that the handle or the lever is pivoted away from the sidewall of the can so that it can be squeezed against the can to effect the dispensing of the contents.
Abstract:
A sound-producing device, for use with a pressurized fluid container, includes a body having an orifice surrounded by an annular seat, a cap facing the seat, and a diaphragm held taut over the seat, the margin of the diaphragm being tightly gripped between the body and cap. The body and cap are locked together within a housing, the housing also serving to mount the sound-producing device on a pressurized fluid container. The body and cap present annular beads of different diameters for deforming and tightly holding the margin of the diaphragm. A flexible strip permanently connects the body and cap. The parts are assembled by aligning, in side-by-side relation, a plurality of members, each comprising a body, a cap, and a connecting strap, and applying a length of adhesive-bearing flexible tape to the plurality of members, the tape adhering to one of the body and cap, preferably the cap, of each member. The line is advanced in stepwise fashion, and the tape severed sequentially between successive members near the downstream end of the line. The strap of the endmost member in the line is folded to bring its body and cap into face-to-face relation with the cut piece of tape, serving as the diaphragm, between them. The folded member is inserted into a housing wherein its body and cap are locked together so as to hold the tape or diaphragm taut over the seat.
Abstract:
A horn device has a trumpet fixture with one or more internal lights. In one embodiment, the trumpet removably attaches to the valve portion of a canister containing a charge of pressurized gas or air. An actuator button on the top of the trumpet fixture is operable to open the valve assembly of the canister and release the pressurized gas or air through an interior passage of the trumpet fixture, causing a transparent or translucent diaphragm to vibrate, thereby producing a loud horn noise that is directed out of the open bell end of the trumpet. One or more light producing elements, such as electric lamps or LED's, a battery power source and an actuator switch device are housed within a rear chamber of the trumpet fixture. A button on the rear of the trumpet is pushed to control actuation of the light producing elements according to several modes of operation, including flash sequence and steady illumination. The produced light is directed forwardly, out of the open end of the trumpet. In an alternative embodiment, a battery powered electronic horn device is placed in the rear chamber to produce the horn noise. In a further embodiment, the trumpet fixture is transparent or translucent and light is transmitted omnidirectionally.

Abstract:
An aerosol spray system for RTV silicone coating materials employs a valve gasket fabricated from a conformable synthetic resinous material that is substantially non-absorbing of moisture, assembled with components that are also moisture-free.
Abstract:
The nozzle for a pressurized container is mounted to the container for shipment and sale by a hook member. The hook member has a hook portion that mounts to the valve cup rim or container rim. An attachment leg connects the hook portion to the nozzle. The hook portion has a slip-fit relationship to the rim on which it is placed. The wall of the hook portion that rests along the outside of the rim is thinner than is the wall that rests along the inside of the rim. This arrangement accommodates the over-cap without displacement or flaring of the nozzle.
Abstract:
A tilt action valve assembly is disclosed which has a cup for mounting to a container, the cup holding a grommet seal which surrounds a valve stem. The grommet seal has a lower portion which surrounds a lower portion of the stem and which provides a seal for engagement with a valve stem seat. An upper portion of the grommet seal is bowed and thin walled to absorb stem displacement above the cup, thus limiting seal displacement below the cup. A lip locks the upper portion to the stem to assure co-movement therewith. Utilizing the valve assembly provides for a maximized opening between the stem seat and seal to optimize the flow of fluid through the stem.
Abstract:
A bowed piston for a pressure operated container has a cylindrical sidewall including an outwardly projecting bowed portion which forms an arch engagable with a sidewall of the container. The bowed arch provides a flexible sealing surface against the sidewall which allows the piston to adapt to out-of-round, out-of-tolerance or dented containers without increasing surface friction and thus prevents the piston from binding within the container. The bowed portion flattens along a part of its length to adapt to these imperfections. Additionally, the bow allows the piston to tilt somewhat within the container without binding and maintains a very thin product film for lubrication as the piston moves upwardly in the container. Consequently, the inventive piston enhances successful utilization of such containers with various products, including those of low viscosity by minimizing binding and/or propellant blow-by in use.
Abstract:
A valve for a pressurized dispensing container has a resilient annular grommet that surrounds a valve stem. The grommet has a lower segment which engages an elongate valve stem opening with a slight interference fit to provide user controllable metering of the product being dispensed. A recess in the lower surface of the grommet contains the stem button from the closed state to the fully open state to provide stability for the stem. The upper portion of the grommet has a restoring boot to assure that the valve is returned to its closed state once manual force is removed from the valve. A boot flange and stem recess engagement together with other dimensional relationships assures that the boot provide the required restoring force throughout the dispensing of product.
