Clean Funnel

For many years, various types and designs of funnels have been used in both industry and home applications for the transfer of both liquid and granulated substances from one container to another by use of a funnel device. Typically the funnel has a large opening that is tapered to a smaller opening which directs and concentrates the flow of material.

Various funnels for domestic and industrial use include a method of capping or sealing at one end of the funnel to restrict or block the flow of material. The proposed CLEAN FUNNEL is a device having a cap or closure at each end of the funnel. The dual closures provide a method for preventing dirt or contamination from entering the funnel during periods of nonuse, thereby maintaining cleanliness and freedom of contamination.

The closures may be secured by either threading both the large and small openings or by a slip cap device which will enclose the respective ends of the funnel device.

FIG. 1 shows the CLEAN FUNNEL with the caps or plugs for each end removed. In this position, the funnel could be used for the conveyance and transfer of materials.

FIG. 2 shows the funnel with the caps or plugs fitted to each end of the funnel. The funnel would be stored as shown in FIG. 2 to prevent contamination of the inside of the funnel. The funnel would then be clean and ready for use in the future merely by removing the caps or plugs as shown in FIG. 1 for reuse.

Referring to the drawings, Numeral 2 indicates the body of the funnel, Numeral 1 indicates the larger cap or plug for the top opening and Numeral 3 indicates the smaller cap or plug for the bottom opening.

In FIG. 1, the larger cap or plug 1 is shown removed from the top opening of the funnel body 2 and the smaller cap or plug 3 is shown removed from the bottom opening of the funnel body 2.

In FIG. 2 the larger cap or plug 1 and the smaller cap or plug 3 are shown fitted to each end of the funnel body 2.

In the farming, ranching, lumber, petroleum, construction, mining, manufacturing and service industries; in homes, schools, offices, stores and shops; in fact, in any human activity where liquids, powders or other free running substances are transferred from containers into small openings, funnels are used to facilitate this transfer. Many times the problem occurs of not having a clean funnel readily available for use.

The CLEAN FUNNEL is a funnel with removable caps or plugs fitted to each opening, and makes available, when needed for use, a funnel free of foreign contamination.

The CLEAN FUNNEL is manufactured so that caps or plugs are fitted to each opening. The caps or plugs are removed when the funnel is in use. After the CLEAN FUNNEL is used, the caps or plugs are replaced and the funnel stored with or without having been cleaned of the substance poured through it. The next time the funnel is used, it wil be free of dust, dirt, grit, or any other type of foreign contaminants. The body of the funnel may be as shown in FIGS. 1 and 2 or of any similar design commonly used for the transmission of liquids and powders from one container to another. The unique and distinguishing feature of this invention is the capping or plugging of both ends of the funnel. In this manner, the interior of the funnel is protected during periods of nonuse from contamination. The funnel may either be cleaned after use and stored in its clean condition, or capped without cleaning to be subsequently used for funneling of the same or a similar substance without becoming dirty or contaminated.

While the specific embodiment of a funnel protected from foreign contaminants by caps or plugs fitted to each opening has been disclosed in the foregoing description, it is understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.
