A valve for a container for dispensing pressurized fluid includes a housing which is mounted on a valve cup, a hollow stem provided in a passage of the housing which stem has at least one lateral inlet opening at its lower end and an outlet opening at its upper end, and a spring. The housing has a circumferential step-like contour with an outer, lower part and a central, upper part. The valve cup follows essentially the step-like contour line of the housing and ends horizontally on the top of the housing close to the stem and a sealing is provided on the upper side of the housing between the housing and the valve cup and which seals at the same time the valve cup against the housing and the stem against the housing.

A manually operated applicator for spraying and dispensing expanding foam chemicals from aerosol containers is provided. The applicator dispenses compressed gas in close proximity to the foam as the foam exits the applicator, which results in improved adhesion of the foam to surfaces. The applicator includes a nozzle, an aerosol inlet for connection to an aerosol container, a gas inlet for connection to a source of compressed gas, and a trigger for operation of the applicator. The nozzle includes outlets for dispensing the foam and the compressed gas.

An article contains an elbow having at least two sections that arc hingcdly attached to one another by means of a hinging joint so that the first section can move in a plane with respect to the second section, wherein the sections define a passageway through which a dispensing straw can extend where the passageway extends all the way through the two sections and perpendicularly through the hinging joint attaching them. The article can include a bendable dispensing straw extending through the passageway of the elbow.

An article includes a can with a valve stem and a dispensing device attached to the valve stem where the dispensing device includes a hollow base, a hollow tube attached to the hollow base the hollow tube having one or more than one hole proximate to its exit end, a sleeve with a finger pad that slides over the hollow tube and an elastic connector attaching the sleeve to at least one of the hollow base and hollow tube, and a sealing gasket residing between the hollow tube and sleeve, wherein the dispensing device can reversibly move between a closed position where the sleeve seals the one or more than one hole in the hollow tube and an open position where the one or more than one hole in the hollow tube is unsealed by the sleeve and the elastic connector provides a restoring force to the sleeve when in the open position that directs the sleeve to a closed position.

An article has a can with a valve stem and a dispensing device, the dispensing device includes a cap over the valve stem, a hollow tube extending through a slot in the cap and attached to the valve stem, a sleeve slidably extending over the hollow tube, a lever hingedly attached to the cap and operatively engaging the sleeve, an elastic feature that provides a force or causes a force to be applied to the sleeve in a direction that tries to move the sleeve to a closed position, and a sealing gasket between the sleeve and hollow tube proximate to the exit end of the hollow tube; where the sleeve seals the hollow tube when in the closed position and displacing the lever towards the can simultaneously unseals the hollow tube and tilts the valve stem, and when released allows the sleeve to restore to a closed position.

A spray foam canister adapter provides a means to attach a convenient trigger assembly to a commercially-available aerosol can containing a spray foam insulating material, for efficient spraying of the insulating material into tight or hard to reach spaces. The canister adapter also provides alternate nozzles and a ninety degree (90) extension for specific insulation spraying applications.

A device to allow for the continuous spraying of pressurized liquid from an aerosol spray can at any angle required, and in locations that can only be accessed through an openings through which an aerosol spray can does not fit, all while automatically preventing backflow of the pressurized liquid through the device.

Disclosed is a system to generate bubbles. The bubbles may be formed to include a substantially or medically pure gas. The bubbles may be formed on demand and in a selected small size.

A tube holder is designed for attachment to a dispensing system. The holder has a base and a holding member extending along an axis Y. A rear side of the base is configured to attach to the dispensing system and a front side of the base is where the holding member is located. And, the base in a plan view has a general quadrilateral shape, for example a rhombus shape.

A device for dispensing pressurized air and/or tire sealant from a pressurized can. The device comprising a cap body, a depressor button with a lock clip, and a hose positioned within the cap body attached to the pressurized can. The lock clip locks the depressor button in the compressed position for ease during use, while a shield element keeps the depressor button in the non-compressed position for safety during non-use. The hose provides an extension to attach to a tire stem valve, while being stored and attached to the cap body of the device.
