The present invention relates to a dispensing device for attachment to a portable container, and more particularly to a dispensing device enabling simple conversion from a storage mode to a dispensing mode, including provision for air flow.
Dispensing devices of some conventional portable fuel containers are usually converted from a storage mode to a dispensing mode by: unscrewing a cap of the dispensing device from the container; withdrawing with one hand the spout, which has been immersed in fuel, and turning the same end to end; removing a plate covering an opening in the cap; inserting the turned spout through the opening; and again screwing the cap with the inserted spout onto the container. The handling of the fuel covered spout requires wearing gloves or washing of hands each time, after handling, which is particularly awkward when the portable fuel container is used for purposes such as, for example, boating or gardening. Turning a fuel immersed spout causes spillage of fuel which is environmentally harmful, even in small quantities.
Some dispensing devices of conventional portable fuel containers provide a stopper for closing the container with the spout protruding, to enable easy access when the fuel container is not in a storage mode. However, the stopper is easily lost or misplaced, and fuel containers left in this configuration pose a safety hazard.
Devices attempting to dispense liquids without providing adequate passage of air to a container do not function acceptably, and some others that open only when pushed down onto a receptacle, spray fuel in all directions, thus creating an environmental hazard, rather than being a safety measure, whereas the present invention functions efficiently and safely with close to zero environmental impact.
It is desirable to provide a container dispensing device that is easily converted from a storage mode to a dispensing mode without directly handling a fuel covered spout.
It is also desirable to provide a dispensing device that closes the fuel container, optionally, with the spout protruding, to dispense fuel in a substantially safe fashion.
Also, it is desirable to provide a dispensing device that has an angled or straight spout which may be rotated to and secured at any desired position by a threaded sleeve which draws the spout's lower flange upward under a lower cap in a sealed fashion.
It is desirable to provide a dispensing device in which a holding mechanism of a second cap has a protruding center pin which facilitates air flow to a container.
Many prior art examples of container dispensing devices have been studied and all found to have dissimilar features and functions. For example, U.S. Pat. No. 4,076,151 A (Littlefield, H. B.) and U.S. Pat. No. 4,311,259 A (Babiol, P.) among others, and while U.S. Pat. No. 3,804,305 A (Rieke, G. T.), provides a spout with exterior threads, it is rotated upward into the container to form a seal, a function differing from the present invention.
Accordingly, one object of the present invention is to provide a container dispensing device which may easily be converted from a storage mode to a dispensing mode handling only dry exterior surfaces of both a second cap and a draw sleeve.
Another object of the present invention is to provide a container dispensing device in which the exterior of a draw sleeve is kept dry by upper and lower seals within a second cap, in a storage mode.
A further object of the present invention is to provide a container dispensing device in which a pouring spout comprises a threaded first end portion and a second end angled configuration having exterior engaging mechanism designed to engage the interior engaging mechanism of a draw sleeve.
Another object of the present invention is to provide a container dispensing device in which a pouring spout is positioned and functions at all times, inside both a first cap, and a draw sleeve.
A further object of the present invention is to provide a container dispensing device wherein a draw sleeve houses an interior engaging mechanism.
Another object of the present invention is to provide a container dispensing device in which a pouring spout is placed at any desired angle position within a container, prior to being converted to a dispensing mode.
A further object of the present invention is to provide a container dispensing device in which the second end outer flange of a pouring spout is drawn to a respective surface under a first cap in a sealed fashion, by clockwise rotation of a draw sleeve.
A further object of the present invention is to provide a container dispensing device in which a draw sleeve rests upon a multi-functional seal cemented to a top edge of an upper extension of a first cap.
Another object of the present invention is to provide a container dispensing device wherein, in a dispensing mode, clockwise rotation of a second cap holding mechanism onto an exterior threaded air vent, causes its protruding center pin to temporarily open an air valve, enabling passage of air to, or from, the container.
Another object of the present invention is to provide a container dispensing device in which conversion from a storage mode to a dispensing mode, and vice versa, is accomplished by utilizing a draw sleeve.
A further object of the present invention is to provide a container dispensing device wherein a draw sleeve is positioned directly above an upper extension of a first cap.
Another object of the present invention is to provide a container dispensing device wherein a second cap houses a draw sleeve in a storage mode.
Another object of the present invention is to provide a container dispensing device in which the exterior of a draw sleeve is kept dry in a storage mode, by upper and lower seals housed within a second cap.
A further object of the present invention is to provide a container dispensing device wherein a pouring spout may be released and returned to a storage position by counter rotation of a draw sleeve.
Another object of the present invention is to provide a container dispensing device wherein, in a dispensing mode, counter-clockwise rotation and removal of a second cap holding mechanism from an existing or manufactured exterior threaded air vent, causes its protruding center pin to close a container air valve positioned therein.
According to a preferred manifestation of the present invention, there is provided a dispensing device. The dispensing device comprises a pouring spout, having a threaded first end portion and second end angled configuration with exterior engaging mechanism, and an outer end flange. A first cap is comprised of an upper exterior threaded extension and lower engaging mechanism with which a respective container opening portion is engaged; it also features a center opening for movably accommodating the spout therein between a retracted storage position, with its first end portion and the draw sleeve with interior engaging mechanism, housed in the opening, and an extended position with the opposite second end portion of the spout being accommodated therein, in the dispensing mode. A second cap, second engaging mechanism, provides for temporarily engaging a respective outer threaded upper extension of the first cap for covering the opening of the first cap and the threaded first end portion of the spout in a sealed fashion, in the storage mode. A holding mechanism engaging the threaded first end portion of the spout is housed within the second cap, which is disconnected from the exterior engaging mechanism of the upper extension of the first cap by counter-clockwise rotation. The spout is withdrawn, held at a desired angle, and the draw sleeve, positioned upon a multi-functional seal, cemented to the top edge upper extension of the first cap, is rotated clockwise engaging the exterior engaging mechanism of the spout's second end, drawing its outer end flange to a surface under the first cap in a sealed fashion, thereby placing the spout in the dispensing mode.
The second cap is rotated, for example, counter-clockwise and its centered holding mechanism uncovers the threaded first end portion of the spout for pouring, after which it is placed and rotated clockwise onto a closed exterior threaded air vent enabling its protruding center pin to depresses and temporarily open the air valve positioned therein, allowing passage of air to the container. Optionally, the air valve may be hand operated. The air valve is closed by counter rotation and withdrawal of the protruding center pin, and the holding mechanism again rotated onto the spout's first end. Reversing the procedures above restores the device from a dispensing mode to a storage mode.
Advantages of the present invention are to provide a dispensing device, quickly converted from a storage mode to a dispensing mode by handling only the dry exteriors of both a second cap and a draw sleeve. The device may be used repeatedly and safely with the spout protruding. The first cap remains engaged with the container at all times and the second cap is not set aside, except if manual operation is desired, but is moved directly from the spout to the air vent/valve, providing adequate air flow, and vice-versa. Also, in the dispensing mode, the second cap may be temporarily turned to a slightly open position to relieve expansion or contraction pressures inside the container. The multi-functional seal is cemented to the top edge of the upper extension of the first cap to keep the under side of the draw sleeve dry in the storage mode, to deter its own removal while operating, and provide a base upon which to adequately function.
A further object of the present invention is to provide a variation wherein an upper extension of a first cap, having exterior threads, is inserted through or otherwise attached to existing or manufactured fuel container caps, thus providing a means of converting them to accommodate the components and perform the functions of the present invention.
Another object of the present invention is to provide a conversion kit comprising an air valve extension designed to fit onto existing or manufactured exterior threaded container air vents, housing an air valve, located and designed to be operated by a protruding center pin of a second cap holding mechanism, or manually.
