Abstract:
Tank tote bags for storing cylinders such as diving tanks, welding tanks, and medical tanks such as oxygen tanks, in separate compartments that can be arranged in either vertical upright positions or horizontal laid down positions. One bag version has two tanks that can be arranged side-by-side in a bag with a mesh material behind the tanks, an open front and open top, and horizontal and vertical straps for holding the tanks together and separate from one another. Another bag version has three tanks arranged in a triangular arrangement. And another version has five tanks arranged in a triangular configuration. A still another version has four tanks arranged in a stacked two by two arrangement in a bag with a closeable top. The bags can be used in pickup truck beds and boats, homes and garages. The bags can be lightweight and can be easily carried and handled by one hand and later folded into small compact spaces.

Description:
This invention relates to tanks, and in particular to lightweight, durable, pliable, and carriable bags for separating and holding combinations of two, three, four and five tanks, such as diving tanks, oxygen tanks and cylinders together in side by side arrangements, and for protecting the exterior of the tanks from being damaged as well as surface areas of storage locations such as homes, vehicles, boats, and the like, from being damaged, and for allowing plural tanks to be handled and/or carried by a single user. 
   BACKGROUND AND PRIOR ART 
   Tanks such as scuba diving tanks, oxygen tanks and cylinders contain pressurized gas that can become hazardous if not properly stored or handled. Additionally, it is preferable that the tanks be consistently transported and stored in a vertical position as opposed to a horizontal position. The horizontal position can cause damage, marring and scratches, thus increasing the likelihood of corrosion. Additionally, storing tanks in horizontal positions on their sides takes up an unnecessary waste of floor space. Merely storing the diving tanks in an upright position is not safe since the unsecured tanks can tip, fall over and hit against one another. Using rope and bungee cords is generally not a practical solution for storing loose tanks in pickup truck beds, garages, boats, dive shops and the like. 
   Backpacks and single tank storage bags have been used by divers to store their cylinder tanks when the tanks are not being used. There are several problems with using the backpacks and single tank storage bags. First, most backpacks do not often allow for the tanks to be stored in upright position on a floor surface. Secondly, backpacks usually only have room for storing up to at most two tanks. Many professional and sportsman divers normally take three or more tanks on a dive trip. The problem becomes compounded when plural divers go to a dive trip. In fact normal safety procedures require two divers teamed up with one another for a single dive. Thus, the divers often need more than two tanks at any given time, and need to safely store and handle these tanks. With current backpacks and single tank storage bags, the user is often forced to handle and carry plural backpacks, and plural single tank storage bags. Thus, backpacks and single tank storage bags do not take care of most divers&#39; needs. 
   The inventor is aware of several types of devices that can be used for storing dive tanks. See for example, U.S. Pat. Nos. 3,964,266 to Bartlett; 4,495,883 to Hoy; 4,889,306 to Boucher; 5,025,935 to Hadachek; 5,082,464 to Clink; 5,267,815 to Feder; 5,299,721 to Cummings; 5,788,475 to Henderson; 5,833,197 to Peabody; and 5,901,890 to Stokes. However, none of these devices singularly or in combination overcomes all of the problems described above. A device sold under the name “Pelican Tank Racks” shows racks for holding four and six air tanks. However, the Pelican Tank Racks require using “carbon steel” that is wrapped in polyester coating layer into large wire cages having large mesh opening. These racks are expensive to hold and carry excessive weight when being used. 
   In addition, the inventor is aware of other types of devices that can be used for storing oxygen tanks. There are wheel carts for oxygen tanks cylinders that carry one (1) tank. These are used by the user to provide some portability while employing the use of the air. Further, there are pouches that also allow portability, and are generally carried or attached to the wheel chairs. 
   The inventor is also aware steel type racks for storage of oxygen tanks. These types of racks are bulky and heavy not allowing for portability. 
   Thus, the need exists for solutions to the problems with the prior art. 
   SUMMARY OF THE INVENTION 
   A primary objective of the present invention is to provide a lightweight and durable tank storage bag for storing and toting two, three, four, or five, cylinder tanks in one carrying bag. 
   A secondary object of this invention is to provide a lightweight and durable tank storage bag for holding tanks in vertical upright positions side by side in a close configuration without abutting one another.

   A preferred embodiment of a tank container bag can include a first compartment having a first flexible and pliable strap frame, adapted for holding a first cylindrical tank therein, and a second compartment having a second flexible and pliable strap frame, adapted for holding a second cylindrical tank therein, the first compartment being attached in a side-by-side to the second compartment in a combined arrangement, wherein the combined arrangement allows for the first cylindrical tank and the second cylindrical tank to be stored in an upright vertical position, a horizontal position, and allows for the bag to be handled and carried by a single user. 
   Pliable and flexible mesh material can be used for covering a rear side of the bag, so that top ends, and front sides of the first and the second cylindrical tanks are left exposed. 
   The bag can have four vertical straps parallel to one another forming a back of the bag with the mesh material attached across the four vertical straps. 
   Additionally, the bag can have an inwardly folded vertical edge of mesh material midway down the mesh material for separating the first tank from the second tank. 
   Underneath the bag can be sets of flexible crossed straps under the compartments for supporting the tanks, therein. 
   The bags can include an upper horizontal strap positioned to pass about upper side portions of the first and the second cylinder, and a lower horizontal strap positioned to pass about lower side portions of the first and the second cylinders. The straps can include adjustable fastening features for allowing the straps to be tightly wrapped about the first and the second cylinders. 
   A third compartment having a third flexible and pliable strap frame, adapted for holding a third cylindrical tank therein, can be attached along a midportion behind the first and the second compartment, the first and the second and the third compartments being arranged in a triangular configuration. Pliable and flexible mesh material can be used for covering rear sides of each compartment of the bag, so that a top ends and front sides of the tanks are exposed. 
   Another triangular configuration can have two rows of compartments(two in the front, three there-behind) for holding five cylindrical tanks. 
   Another version can include a top lid formed from a pliable and flexible material that can be positioned from a flap open position to a closed position, by zipper fasteners, and the like. Compartments can each contain tubular containers each formed from tubular pliable and flexible mesh material adapted for substantially enclosing the first and the second cylinders therein. A bottom cover can close off the bag and be formed from a pliable and flexible material. 
   The top lid and the bottom lid can each have a webbing material formed from a pliable and flexible material running down a middle portion of a pliable and flexible mesh material. Side straps and webbing can also be used for adding rigidity and strength to the bag, and have upper looped portions that can function as handles for raising and lowering the bag. 
   Further objects and advantages of this invention will be apparent from the following detailed description of the presently preferred embodiments which are illustrated schematically in the accompanying drawings.
