Fuel container

Abstract

A fuel container includes a body defining a volume for receiving fuel. The body has an inlet and an optional vent. The inlet extends upward as a spout and has a threaded collar closed by a threaded cap. A gas expansion path is provided between the inlet and the vent. The spout has a guide for receiving and positioning a dog-leg portion of a fuel dispenser nozzle. A restriction at the throat of the spout prevents the fuel dispenser nozzle from being inserted into the container beyond a preselected distance, thereby preventing recoil and spillage.

Description

Technical Field

[0001] The present invention relates to a fuel container, can or cartridge, hereinafter referred to as a fuel container. In particular, the present invention relates to a fuel container for storing and dispensing gasoline, diesel or similar liquid fuels. More particularly, the present invention relates to a portable fuel container, which typically holds 5 to 25 liters of liquid fuel when full. Background Art

[0002] When filling a fuel container, fuel backflow or recoil occurs when there is an air lock in the fuel container and may cause spillage. This problem is exacerbated at higher flow rates. Therefore, when dispensing into a fuel tank or container, automatic fuel pumps that dispense liquid fuel need to be operated carefully and at a slow speed to avoid fuel backflow or recoil. This causes users to spend longer than expected at the fuel dispensing pump.

[0003] Filling a liquid fuel container is often problematic because the user is not always able to measure the level of fuel in the fuel container during filling, as the fuel container is often opaque, and therefore the user again tends to dispense the fuel very slowly as a precaution against kickback. This problem is exacerbated in low light or darkness.

[0004] Likewise, emptying liquid fuel containers is problematic because overflows sometimes occur due to sticking caused by an air lock or partial vacuum in the container, which causes the contents to be expelled and become a "sticky" flow when the contents are not expelled by a continuous gas flow.

[0005] Currently, most fuel dispensing pumps, such as those at consumer roadside fueling stations, have a hose connected to a fuel nozzle that automatically shuts off fuel through a Venturi effect that triggers a shutoff valve when fuel in the vehicle's fuel tank reaches the opening on the fuel nozzle. Fuel spillage occurs when the fuel container is filled before the shutoff valve is triggered. This causes fuel to spill from the fuel container before pumping stops, which results in waste, pollutes the environment, and presents a flammable hazard.

[0006] Therefore, the fuel nozzle does not always shut off the fuel at the correct level in the fuel container being filled, as the venturi effect does not always trigger the shut-off valve. This results in fuel flowing over the fuel container and its handle, and thus causing unpleasant fumes in the vehicle.

[0007] To avoid these problems, the user must either fill the fuel container very slowly or underfill the fuel container, the former resulting in extra time to fill the container and the latter resulting in the fuel container being filled to less than the full capacity of the fuel container.

[0008] Another problem that arises during filling of a fuel container is caused by the user having to lift the fuel container and orient it to receive the dispenser nozzle because most modern fuel dispensers have a kink or dog-leg nozzle toward the end of the fuel nozzle so that the tip portion is bent away from the axis of the main dispenser nozzle. The bend or kink is sometimes referred to as a knuckle and is a bend at an angle in a dispenser nozzle that is designed to be placed into the inlet of a vehicle's full fuel tank.

[0009] Nozzles are often color-coded to indicate which type of fuel they dispense. Different types of fuel dispensers have specially sized nozzles to prevent accidentally filling the tank with an incompatible fuel. For example, the nozzle on a diesel pump (diesel) is often larger than a nozzle used to dispense leaded or unleaded gasoline (petrol), so that the diesel cannot fit into the filler tube of a vehicle tank designed for gasoline (petrol). However, the larger diameter diesel nozzle is impractical, and many automotive diesel pumps are already fitted with standard gasoline nozzles.

[0010] Trying to hold the fuel container at the correct angle while also lifting the fuel nozzle and hose increases the chance of spillage and is not always easy for the user, especially if they are frail or infirm. This is due to the strain and discomfort caused to the person who typically must hold the fuel container with one hand and tilt it while using the other hand to support the weight of the gasoline pump hose and dispenser nozzle, orient the fuel container to the fuel nozzle, and control the fuel dispensing trigger. As mentioned previously, this is particularly difficult for a frail or elderly user to do alone and independently.

[0025] Another object is to provide a fuel container which can be easily filled without spilling, thereby improving the safety of the petrol station forecourt.

[0026] Another object of the present invention is to provide a fuel container that can be easily filled to a preselected level in one attempt to depress the trigger of a fuel pump gun. Summary of the invention

[0027] According to a first aspect of the present invention, a fuel container is provided, comprising: a body for receiving fuel, the body having a handle and an inlet, the inlet having a neck, the neck extending upward and arranged at an angle relative to the upper surface of the body, and having a threaded collar that can be closed by a threaded cap, the length of the neck from the opening of the neck to the upper surface of the body defining a guide, the guide being used to receive and orient the dog-leg portion of the nozzle of a fuel dispenser to prevent the nozzle of the fuel dispenser from twisting when fully inserted into the neck; and being provided with a shoulder, the curved nozzle abutting against the shoulder; the guide and the shoulder orient and position the dog-leg portion of the nozzle at a preselected distance within the neck, so that the upper surface of the liquid fuel dispensed in the container causes the venturi closing mechanism to be triggered at a predetermined volume of dispensed fuel.

[0028] Ideally, the body receiving the fuel has a handle integrally formed with the body. In a preferred embodiment, the handle is formed together with the fuel container by a blow molding process. Optionally, the handle has a grip, such as a grip made of a rubber material, for ease of carrying.

[0029] Preferably, the neck extends upwardly, pointing away from the rear of the container, as the horizontal upper surface of the body is at an angle of between 35° and 75° relative to the spout from the body.

[0030] Preferably, the length of the neck from the opening of the neck to the upper surface of the body is between 50% and 99% of the length of the dog-leg nozzle end of the nozzle of the fuel dispenser. For a diesel fuel dispensing nozzle, this equates to between 5.5 cm and 11.0 cm, preferably between 6.0 cm and 10.0 cm. For a gasoline fuel dispensing nozzle, this equates to between 5.5 cm and 11.0 cm, preferably between 7.0 cm and 9.5 cm.

[0031] Therefore, the length of the neck is between 4.5 cm and 7.5 cm, and the ideal length is basically 6 cm.

[0032] In some embodiments, a guide for receiving and orienting a dog-leg nozzle is provided with a narrowed throat sized to receive the diameter of a diesel or gasoline fuel dispensing nozzle, the narrowed throat preventing the fuel dispenser nozzle from twisting when fully inserted into the neck. The throat may be defined by one or more raised portions or ribs extending along the neck, thereby reducing the diameter of the neck to prevent lateral and rotational movement of the nozzle when fully inserted into the neck.

[0033] Ideally, the shoulder includes a thicker portion of material that acts as an end stop against the tip of the nozzle. In some embodiments, the end stop against which the dogleg nozzle abuts is defined by an interior region of the handle. In another embodiment, the end stop may be integrally formed on the interior surface of the body of the fuel container. In other embodiments, the end stop may be defined by a circular or annular protrusion that is sized and arranged to abut the tip of the nozzle.

[0034] When the container is filled to the specified volume of the container, the guide and shoulder together place and position the dogleg nozzle at an optimal distance from the upper horizontal plane of the fuel surface. At this optimal distance, when the fuel reaches the upper liquid fuel level in the container, further fuel dispensing is prevented starting from the maximum fill level with the activation of the venturi shut-off mechanism.

[0035] Furthermore, the guide and shoulder orient the nozzle of the fuel dispenser to ensure that the nozzle of the fuel dispenser can only be fully inserted into the neck in one direction. This not only ensures that the nozzle can only be inserted in one way, but also assists the user by enabling the user to rest the fuel container on level ground and thereby improve stability when filling the tank to ensure that the tank is filled to the correct maximum volume of the tank.

[0036] Optionally, a space or gap is provided in the neck to allow air exhausted from the fuel container to escape without causing a pressure build-up, thereby ensuring a smooth filling experience at normal atmospheric pressure as the venting effect through the gap avoids a pressure build-up.

[0037] Thus, the present invention prevents overflow due to recoil, since the fuel nozzle is positioned and held in an optimal position to ensure that the venturi valve is triggered at the exact desired volume. Thus, even when fuel is dispensed quickly, there is no recoil to force fuel out of the container before the shut-off valve in the fuel dispenser is activated, since there is a gap of several centimeters between the maximum level height and the opening of the neck.

[0038] There is a bend about halfway along the length of the neck from the opening of the neck to the shoulder. The dog-leg nozzle end of the fuel dispenser nozzle rests on the seat. The narrowing of the diameter from the neck to the throat, the bend of the neck and the shoulder all help guide and orient the dog-leg nozzle end of the fuel dispenser and help prevent the nozzle from twisting when fully inserted. Thus, the fuel pump dispenser nozzle is always located at a precise distance from the upper surface of the fuel. In this configuration, when the precise maximum level of fuel is reached, the flow of fuel from the pump is immediately stopped.

[0039] Thus, the guide and end stop in the neck or spout receives and positions the gasoline pump dispenser nozzle and enables the user to quickly fill the fuel container without backflushing.

[0040] An advantage of having an angle or kink or bend in the neck is that it prevents a dog-leg portion of the nozzle of the fuel dispenser. Thus, the neck helps define a guide for receiving and orienting the dog-leg nozzle end to prevent the nozzle of the fuel dispenser from twisting when fully inserted into the neck. A shoulder is provided between the kink and the upper surface of the dispensed fuel. The shoulder helps orient and position the dog-leg nozzle at a preselected distance within the container and helps prevent the nozzle of the fuel dispenser from twisting.

[0041] Once filled and the cap placed on the opening, the fuel container can be transported and stored without generating any vapors or odors, as there is no longer any spillage.

[0042] Ideally, the inlet has a larger inner diameter than the nozzle of a standard fuel dispenser and receives the nozzle of the fuel dispenser to fill the container with liquid fuel. The inlet is also used to discharge liquid fuel from the container.

[0043] Preferably, a vent, also called a grit valve or cap, is provided and serves as an air vent during emptying of the liquid fuel from the container. The vent or grit valve or cap acts as a siphon that allows air to flow into the container and helps prevent so-called sticking. When air enters the container through the vent, the liquid fuel drains smoothly and continuously from the container.

[0044] This arrangement enables the inlet to support the nozzle at an optimal angle and locate the nozzle opening in the correct position of the fuel filling container in the container. Thus, when the nozzle of the fuel distributor is in the inlet channel, automatic fuel cut-off is achieved by the Venturi effect.

[0045] The container may comprise a fully removable screw cap or cap. Such a cap may be attached or tethered to the container to avoid loss.

[0046] In some embodiments, the vent has a cap and during the discharge of liquid fuel from the container, the cap is removed or opened, allowing air to pass through the vent while fuel is discharged from the container through the fuel inlet. This helps prevent fuel from sticking.

[0047] In some embodiments, the fuel container has an integrally formed handle for carrying or lifting the container. Optionally, a contour pattern or other grip may be formed with the handle.

[0048] In some embodiments, the fuel container includes a fuel expansion zone that allows the gas or smoke to expand when the internal volume is filled. In this way, the expansion zone can be separated from the internal volume but connected to the internal volume fluid. The fluid expansion zone is ideally located above the internal volume.

[0049] For example, a fluid expansion zone may be defined in the handle. For example, the handle may include a hollow structure in which smoke or gas may expand. In this way, for example, a nozzle of a fuel dispenser may be inserted into the fuel inlet and the internal volume filled to the full level of the container, below the neck, leaving the first channel open for gas expansion and allowing air to be vented from the container during filling, thereby avoiding gas locks.

[0050] Ideally, the body is formed of a thermoplastic or thermosetting polymer or metal or alloy material, which is also the case of a cap that seals the container at the spout. In some embodiments, the container is formed into a single mold by, for example, blow molding, from a thermoplastic material such as acrylonitrile butadiene styrene (ABS) or high density polyethylene (HPDE).

[0066] Referring to the drawings, there are shown some different embodiments of a fuel container 99 having a body 3 defining an interior volume 71 for receiving and storing fuel. Figure 1 The body 3 of the container shown is substantially rectangular.Some of the embodiments shown in the figures are formed from a strong rigid thermoplastic material formed by a blow moulding process.

[0067] One end 66 of the handle 5 is connected to the body 3, and the other end 67 of the handle is connected to the neck 4. The shape of the handle 5 enables the user to hold his hand tightly around the handle when carrying the container.

[0068] In some embodiments, the handle 5 is hollow and defines a fluid passageway that serves as a gas expansion volume, which may typically be between 10% and 15% of the internal volume of the container.

[0069] The inlet 1 is defined at the end of a neck 4 which extends upwardly and away from the body 3 of the fuel container 99 at an angle of between 35° and 75° relative to the upper surface of the body 3 .

[0070] The size and shape of the inlet 1 and the neck 4 are designed to receive the first tubular portion 82 of the nozzle 85 of the fuel dispenser so that fuel can be pumped into the body 3. The inlet 1 is shaped, for example with grooves or with rifling, so that air can escape when fuel enters the container 99.

[0071] The body 3 has a base 43 which rests on the ground when the container 99 is filled. A vent hole 2 is provided on the top surface of the body 3 on the side opposite to the inlet 1. The bottom surface area of ​​the body is larger than the surface area of ​​the upper surface of the body to improve the stability of the container.

[0072] The neck 4 has a collar 9A with threads 10A for receiving the cap 6A. The vent 2 also has threads 10B on the collar 9B of the vent 2 for receiving the cap 6B. In an alternative embodiment, a one-way valve can replace the cap 6B described below. The threaded collars 9A and 9B enable the lids or caps 6A and 6B to be connected, respectively.

[0073] The covers or caps 6A and 6B are connected to the collars by tethers 8A and 8B respectively, which ensure that the caps cannot be lost.

[0074] Inlet 1 includes a neck 4 that slopes upwardly from the top surface of body 3 so that a nozzle 85 of a fuel dispenser may be inserted into the neck and positioned therein as described below without requiring a user to lift or tilt fuel container 99 as with previous fuel containers.

[0075] Optionally, the neck 4 is supported below by a rounded or perforated support rod 11, which provides strength and prevents the neck from collapsing. A lanyard connection point may be formed on the support rod 11, for example for an identification tag (not shown) or for hanging on a hook for storage purposes.

[0076] The neck 4 is angled between 35° and 75° relative to the top of the fuel container 99. This enables the venturi effect to trigger a shut-off valve (not shown) in the fuel nozzle 85 when the liquid fuel reaches a maximum fill level in the container, as described below.

[0077] exist Figures 1 to 11B and Fig.13 In the example shown, the neck 4 is arranged at substantially 45° relative to the top surface 46 of the container 99 . Figure 2 The embodiment shown is a fuel container having an Archimedean screw in the spout of the fuel container to assist in the discharge of the contents from the fuel container and to allow air to enter the container to ensure smooth discharge of the liquid contents. The Archimedean screw also assists in positioning the fuel dispensing nozzle and in securing the fuel dispensing nozzle when the fuel dispensing nozzle is inserted into the neck of the container.

[0078] Figure 3 The illustrated embodiment is a fuel container having a grip on the handle of the fuel container to aid in gripping the container during filling.

[0079] As shown in Figures 4, 5, 6, 9 and 13, in this neck 4, the neck 4 supports a fuel dispenser nozzle (not shown). The dog-leg shape of the junction of the container and the neck 4 ensures that the fuel dispenser nozzle is in a precise position where the liquid level venturi effect of the maximum fuel level distance triggers the automatic shut-off valve in the fuel dispenser nozzle when the liquid level in the container volume 3 reaches the full level 91. This is Fig.13 is shown in more detail in .

[0080] Reference Fig.13 The length of the neck 4 is slightly less than the overall length of the nozzle of a standard fuel dispenser. The overall length of the nozzle of the fuel dispenser includes a first tubular portion 82 extending from a handle 85 and a second tubular portion 81 extending from the first tubular portion.

[0081] Typically, for a gasoline dispenser, these portions are between 5.5 cm and 11.0 cm in length, preferably between 7.0 cm and 9.5 cm in length. When fully inserted, the nozzle 84 is positioned and retained by the angled neck 4 and shoulder 61. When oriented and positioned in this manner, the nozzle 84 is used to dispense fuel to the confines defined by the upper fuel level indicator 91 of the container 99. The fit of the shoulder 61 and the narrowing of the inlet in the neck 4 retains the nozzle of the fuel dispenser and prevents the nozzle of the dispenser from twisting.

[0082] In use, the heavy fuel gun 85 rests on the threaded lip portion 10A of the neck 4. To help prevent the weight of the fuel nozzle from tipping over the container body 3, the sides 44 of the body 3 taper to a wider footprint or base 43, thereby helping to ensure the stability of the fuel container or tank when resting on the ground.

[0083] like Figure 6 and Fig.13 As shown, when placed on the lever surface, the top surface of the liquid in the internal volume 71 of the body 3 is flush and parallel to the base 43 of the body. The neck 4 is shown to support the nozzle 84 of the fuel dispenser in the neck 4, which enables the nozzle venturi shut-off mechanism (not shown) of the fuel dispenser to operate to shut off the flow when the top surface of the fuel liquid rises to hit the dispenser nozzle tip. Thus, advantageously, the container is filled without spillage.

[0084] The length of the neck 4 from the opening of the neck 4 into the body 3 to the open end of the neck 10A is preselected to automatically fill the internal volume 71. The preselected length is 99% to 50% of the length of a gasoline or diesel fuel nozzle. Fig.13, the neck 4 is shown as being approximately 90% of the nozzle length. Thus, when the fuel nozzle is fully inserted into the inlet 1, the nozzle tip of the fuel dispenser extends beyond the upper surface 46 of the body 3, and the body can then be filled while resting on the base 43 until the liquid level 91 rises to just below the upper surface 46 of the body 3. Figure 6 and 13 As shown, the interior volume 71 is filled with liquid to a level 91 just below the upper surface of the body.

[0085] Smooth discharge of the fuel can be ensured by opening the vent hole 2. However, in some embodiments, gas channels and ridges or similar devices are provided on the inner surface of the neck 4, which form a channel for air to enter the container when the fuel is discharged from the neck.

[0086] so, Figure 1 to 1 Some embodiments shown in Figures 1 and 13 are easier to use than existing fuel containers and provide safer access to the interior volume due to the aperture providing an internal elongated neck.

[0087] The top fluid channel 5 and the neck 4 diverge towards the body 3 so that a user can insert their hand between these fluid channels as a handle for carrying this embodiment.

[0088] The body of this embodiment slopes rearwardly from the second end B in an inclined outer surface 44 below the inlet 1 to restrict tipping, for example, when the nozzle is inserted into the inlet 1 and a weight is placed on the neck inlet.

[0089] The body also includes a recessed base 43 and bumper edge 45 to respectively aid resting on the ground and also to prevent tipping.

[0090] Reference Fig.13 , a container is shown in which a handle 5 is connected to the body of the container at a rear end 66 and a front end 67. The handle is also integrally formed with the neck 4 at the front end 67. A first distal end 66 of the handle is connected to the body 3.

[0091] The nozzle of the fuel distributor comprises a first tubular portion 82 connected in series to a second tube 81. The first and second tubes are straight. The nozzle of the fuel distributor has a bend 83 at which the first tubular portion 82 is connected to the second tube 81. The first tubular portion 82 has a distal end away from the bend 83, which is connected to a handle 85 of the fuel nozzle. The second tube 81 has a distal end 84 away from the bend 83. The distal end 84 is the fuel discharge port of the fuel nozzle.

[0092] As a result, when the nozzle 84 of the fuel dispenser is inserted into the neck 4, the tip of the nozzle 81 is oriented to face the upper surface of the fuel and each portion of the nozzles 81, 82 and 83 is prevented from twisting when fully inserted into the neck 4 by the shoulder 61 defined by the interface with the material forming the handle and the narrowed throat of the neck 4. The shoulder 61 against which the dog-leg nozzle portion 83 abuts helps to position and orient the nozzle 84 of the fuel dispenser at a preselected distance in the neck so that the tip of the nozzle contacts the upper surface 91 of the liquid fuel being dispensed.

[0093] The connection of the handle 5 to the neck 4 forms a restriction 61 in the inlet 1. The restriction 61 provides a bend in the neck 4. The bend in the neck 4 is at about the same angle as the bend 83 in the fuel nozzle. The restriction 63 in the neck 4 thus blocks the nozzle of the fuel dispenser at the bend 83, and when the internal volume 71 of the container 3 is full of fuel, the discharge end 84 of the nozzle is conveniently positioned just below the surface level 91 of the fuel. For example, the correct full capacity of the fuel container may be 5, 10 or 25 litres. This may be Fig.13 Seen in.

[0094] refer to Fig. 12A and 12B , which shows an adapter insert 55, the purpose of which is to enable a nozzle of a fuel dispenser from a petrol (gasoline) fuel pump to be used with a fuel container originally intended for use with diesel (diesel) to be converted into a container for use with a petrol (gasoline) dispensing fuel nozzle. The adapter insert 55 is arranged to be placed in the throat area of ​​the inlet 1 of the neck 4.

[0095] In one embodiment, when filling different embodiments of the container with gasoline, the filling hose stops at a "knuckle" in the hose. This allows the container to be filled substantially to a 5, 10, 15 or 25 liter fuel container before the venturi effect causes the pump to shut down. Due to the different diameters of the diesel hose, such a hose can be pushed further into the container, causing an earlier shutoff (about 3 liters, for example 2 liters earlier than 5 liters).

[0096] In this way, the adapter insert can block the diesel hose from entering the container further to allow pumping of exactly 5 liters without splashback or spillage.

[0097] The present invention has been described by way of example only, and it will be appreciated that changes may be made to some of the embodiments described above without departing from the scope of protection defined in the claims.
