FUNNEL
An improved funnel allows for easier filling of containers. The funnel allows containers to be filled more completely and to be more easily filled with viscous or granulated material. The funnel is also stabilized during use to minimize the risk of spilling.
The present application claims the benefit of U.S. Provisional Application No. 60/841,433, filed Aug. 31, 2006, which is incorporated herein by reference.
BACKGROUND OF THE INVENTION1. The Field of the Invention
The present invention relates to funnel. More specifically, the present invention relates to an improved funnel which allows for easier use in filling containers such as jugs, bottles, and the like.
2. State of the Art
Currently available funnels allow a person to more easily fill a container, but suffer from several setbacks. Existing funnels tend to drain slowly, cause air to become trapped in the container, tend to easily fall out of the container, and require supporting of the funnel during use. These and other limitations of existing funnels make them difficult to use in many situations.
There is thus a need for an improved funnel which overcomes the limitations of available funnels and which is more convenient to use.
SUMMARY OF THE INVENTIONIt is an object of the present invention to provide an improved funnel.
According to one aspect of the invention, a funnel is provided which attaches to a container. Attachment to a container provides a more secure funnel, allowing for easier use and reducing the risk of spills.
According to another aspect of the invention, a funnel is provided without an elongate neck extending into the container. Such a funnel allows for faster filling of the container and allows for easier use with highly viscous or granulated materials.
These and other aspects of the present invention are realized in a funnel as shown and described in the following figures and related description.
Various embodiments of the present invention are shown and described in reference to the numbered drawings wherein:
It will be appreciated that the drawings are illustrative and not limiting of the scope of the invention which is defined by the appended claims. The various embodiments shown accomplish various aspects and objects of the invention. It is appreciated that not all aspects of the invention may be clearly shown in a single figure. Thus, multiple figures may be used to illustrate the various aspects of a single embodiment of the invention.
DETAILED DESCRIPTIONThe invention and accompanying drawings will now be discussed in reference to the numerals provided therein so as to enable one skilled in the art to practice the present invention. The drawings and descriptions are exemplary of various aspects of the invention and are not intended to narrow the scope of the appended claims.

Additionally, such a funnel is relatively unstable during use. It is appreciated that much of the material passing through the funnel 10 resides in the cone 14. The cone 14 filled with material is supported only by the neck 22. Thus, the funnel 10 tends to move when material is poured into the funnel, possibly causing a some of the material to spill out of the cone 14 and on to the outside of the container 30 of the area around the container. The funnel 10 may even fall out of the container 30.
A further limitation of such a funnel 10 is that the neck 22 extends downwardly into the container 30. In such a configuration, granular solids can not be filled above the neck 22, requiring the person to only partially fill the container or to try to lift the funnel while pouring material. Liquids may fill the container 30 above the neck 22, but coat the lower portion of the neck in the process, making the funnel dirty. When transferring a liquid such as used motor oil, additional mess is undesirable.

Additionally, the funnel 42 may include a slight shoulder or lip 82 which overlaps the rim 86 of the container 70. A lip 82 of some degree is typically desirable so that the funnel may be tightened onto the container 70. A lip 82 providing an opening the same size as the container opening may aid in filling the container 70, especially if the interior surface 90 of the funnel 42 does not present any ridge or shoulder at the lip 82, as is shown in
The funnel of
It will also be noted that the opening in the container 70 becomes the size limiting factor for flow of liquid, granules, etc. rather that the interior of the neck. Thus, the flow rate into the container is substantially higher.
An additional advantage of the present invention is that the funnel can be left on the container. Gallon containers are often used to store granulated items, such as ice melting material so that it can be spread more easily than when it is contained in its traditional plastic bag. With the present invention the funnel can be left attached to the top of the container while the salt is being spread by turning the container on its side and shaking it back and forth. With a conventional funnel, the funnel would first be removed prior to applying salt or other granulated material. The user must then remember to return the container to the location at which he or she left the funnel for later refilling of the container. With the present invention, the funnel can be left on the container and thus the risk of misplacing the funnel or otherwise separating the funnel and the container is eliminated.
Additionally, if the container is being used to pour items out, the funnel can be used as a pouring mechanism so as to minimize splatter. For example, if paint were to be poured into a one gallon container, the funnel could then be used to help pour the paint out of the container without splashing etc. This may be facilitated by having the funnel include a one or more corners such as is shown at
Likewise,
Thus there is disclosed an improved funnel. It will be appreciated that numerous changes can be made to the present invention without departing from the scope or spirit of the disclosure. The appended claims are intended to cover such modifications.
Claims
1. A funnel comprising:
- a body having a first end having a first opening and a second end having a second opening smaller than the first opening; and
- threads formed about the second opening to allow releasable attachment of the second opening to an opening of a container.
2. The funnel of claim 1, further comprising a shoulder formed adjacent the threads and configured for contacting a rim of the container.
3. The funnel of claim 1, wherein the shoulder forms a lip configured for extending into the opening of the container.
4. The funnel of claim 1, further comprising gripping means formed on the second end.
5. The funnel of claim 1, wherein the body is conical.
6. The funnel of claim 1 wherein the threads formed in the second opening are configured to receive a 38-400 standard thread opening.
