The present teachings relate to a funnel. The funnel may be particularly useful with fill ports of recreational vehicles and filling of recreational vehicle fluid holding tanks. The funnel may be adaptable for multiple means of filling with fluid, from hoses to containers.
Recreational vehicles (RVs) typically include amenities for off-grid comfort. These amenities include electricity through onboard batteries and/or an incoming electricity connection, clean water through one or more water tanks and/or a fresh-water connection, and sewage storage and disposal through one or more holding tanks and/or sewage connections. To fill the one or more water tanks with fresh water, for later use, RVs generally include one or more inlet ports along an exterior wall and in fluid communication with the one or more water tanks located under the body of the RV. To fill the water tanks, a hose is placed into the inlet port and a user filling the tank holds the hose until the tank is full. This can be cumbersome and time-consuming, as the individual must remain at the port holding the hose and ensuring the hose does not slip.
In addition to filling the water tanks with fresh water, it is common to need to fill the tank with chemical treatments, other liquids, or just water from containers. These containers can range from smaller (e.g., easily held with one hand) to larger (e.g., 1 gallon, 2 gallons held with two hands). For example, antifreeze may need to be poured into the tanks for proper winterizing. As another example, when off-grid, users may refill their water tanks via large containers holding fresh water, as a hose connection is not available. For the smaller containers, a small funnel can be utilized with one hand holding the funnel and another hand holding the container. For the larger containers, typically two individuals may be needed to empty the container into the fill port and tank. For example, a first individual may hold the larger, heavier container with two hands while a second individual holds the funnel in place at the port.
What is needed is a device which is adapted to engage with a hose and allow for the hose to be sustained in place while filling the tank. What is needed is a device which is adapted to work with both small containers and large containers. What is needed is a device which allows for a user to fill a tank hands-free with a hose. What is needed is a device which allows for a single individual to fill a tank with a heavier container.

This angle may allow for the adapter portion to provide support to the weight of first section when filled with fluid, sufficient distance from an outlet portion to avoid interference, or both.
The one or more adapter portions may be at an angle relative to one or more outlet portions. The angle between the two portions may allow for the adapter portion to be free of contact from one or more surfaces, walls, ports, and the like while allowing insertion of one or more outlet portions into one or more ports, openings, channels, and the like.

For example, the first mating portion 18 may be integrally connected to the output section 12. The first mating portion 18 may bifurcate into the outlet portion 24 and the adapter portion 26.
Any numerical values recited in the above application include all values from the lower value to the upper value in increments of one unit provided that there is a separation of at least 2 units between any lower value and any higher value. These are only examples of what is specifically intended and all possible combinations of numerical values between the lowest value, and the highest value enumerated are to be considered to be expressly stated in this application in a similar manner. Unless otherwise stated, all ranges include both endpoints and all numbers between the endpoints.
