A funnel assembly which includes an interior funnel and an exterior funnel. When an interior funnel is inserted into the exterior funnel, three equally spaced raised projections prevent contact between the outer surface of the interior funnel and the inner surface of the exterior funnel. This arrangement creates air passages between the two funnels for the venting of displaced air. Consequently, the liquid being poured runs faster into a container, unaffected by the upward movement of the vented air. The interior and exterior funnels are individually, integrally formed and come together as the exterior funnel is snapped into place next to the interior funnel by three wedges protruding on the outside spout of the interior funnel. These wedges are forced against the spout of the exterior funnel and hold the two funnels equidistant to each other.

BACKGROUND OF THE INVENTION 
1. FIELD OF THE INVENTION 
The present invention relates to funnels and is an easy-flow funnel 
assembly adapted for venting displaced air from a container being filled 
with liquid, thereby allowing the liquid to run faster into the container 
through the central spout of the funnel assembly. 
2. DESCRIPTION OF RELATED ART 
The use of funnels to pour liquids and other fluid substances is well-known 
and established in the related art. For example, U.S. Pat. No. 4,494,585 
issued to Waldecker outlines a funnel that includes a ventilation 
subassembly. The ventilation subassembly includes a large ventilating 
passage that communicates with the interior of the container being filled 
and an angled pipe section. The angled pipe section is interconnected to a 
flexible conduit that runs outside of the funnel. The conduit is routed 
back to the open mouth of the funnel so it discharges downwardly into the 
funnel's mouth and beneath a baffle. Thus, the air being vented, as well 
as any fluid, passes through the angled pipe section, into the flexible 
conduit, and is discharged from the flexible conduit back into the 
funnel's mouth. Although this is a self-ventilating funnel, it is bulky 
and cumbersome to use. Also the flow area available for venting is limited 
by the size of the conduit and the angled pipe section. 
U.S. Pat. No. 5,277,234 issued to Warstler outlines a self-ventilating 
funnel that is less bulky and cumbersome to use. The funnel includes a 
plurality of spaced and channelled depressions formed on the outside 
surface of the funnel. These depressions are arranged so the air is vented 
from the container up along the outside surface of the funnel. This funnel 
is provided with a flapper valve arrangement in the guide conduit portion 
to prevent overfilling of the container. However, because the depressions 
are on the outside surface, there is no other means for preventing 
unwanted spillage of material from an overflowing container. In other 
words, one cannot establish a leak tight connection between the funnel and 
the container being filled. 
While some of the foregoing related art funnels include some mechanism for 
self-ventilating, there is a need for a self-ventilating funnel that is 
simple in design and usage, which minimizes or avoids unwanted spillage. 
It is also desirous for the self-ventilating funnel to allow the fill 
operation to be performed by one person. 
None of the above inventions and patents, taken either singly or in 
combination, is seen to describe the instant invention as claimed. 
SUMMARY OF THE INVENTION 
The funnel assembly includes an exterior funnel and an interior funnel. 
When the interior funnel is inserted into the exterior funnel, three 
equally spaced raised projections prevent contact between the outer 
surface of the interior funnel and the inner surface of the exterior 
funnel. This arrangement creates air passages between the two funnels 
through which displaced air is vented. Consequently, the liquid being 
poured runs faster into the container, unaffected by the upward movement 
of the vented air. The interior and exterior funnels are individually, 
integrally formed and come together as the exterior funnel is snapped into 
place about to the interior funnel. Three wedges protruding on the outside 
spout of the interior funnel are forced against the spout of the exterior 
funnel and hold the two funnels equidistant to each other. 
Accordingly, it is a principal object of the invention to provide an 
easy-flow funnel assembly adapted for venting displaced air from a 
container being filled with liquid, thereby allowing the liquid to run 
faster into the container through the spout of the funnel assembly. 
It is an object of the invention to provide improved elements and 
arrangements thereof in an apparatus for the purposes described which is 
inexpensive, dependable and fully effective in accomplishing its intended 
purposes. 
These and other objects of the present invention will become readily 
apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
The present invention is a self-venting apparatus 10 made up of an interior 
funnel 11 and an exterior funnel 12, as shown in FIG. 1. As best 
appreciated from FIG. 4, the spout 22 of the exterior funnel 12 has a 
larger inner diameter than the outer diameter of the spout 20 of the 
interior funnel 11. The interior funnel 11 is inserted inside the exterior 
funnel 12, being dimensioned so that a terminal portion 24 of the interior 
funnel 11 extends through the terminus 26 of the exterior funnel 12. 
The interior funnel 11 has a plurality of equi-spaced raised projections 13 
below the outside perimeter, whereby the interior funnel 11 and the 
exterior funnel 12 stay spaced to define a plurality of vent passages (See 
FIG. 4, items 16 and 17) between the two funnels. These raised projections 
13 enable a flow of air coming up from the interior of the container 15 to 
pass between the sides of the two funnels. 
Wedges 14 on the outside spout 20 of the interior funnel 11 are provided 
above the terminus of the interior funnel 11, where the exterior funnel 12 
is secured in place in relation to the interior funnel 11. Thus, the 
self-venting apparatus 10 can also be taken apart, with the exterior 
funnel 12 being separated from the interior funnel 11 and used by itself 
to drain a thicker second liquid. 
An exploded environmental perspective view is provided in FIG. 2. This 
shows how the interior funnel 11 fits in the exterior funnel 12. The 
funnels nest in coplanar-surface relationship to each other, although the 
raised projections 13 on the outside perimeter of the interior funnel 11 
space the exterior funnel 12 from contiguous contact with the interior 
funnel 11. The raised projections 13 allow the vent passages 16 and 17 to 
be formed between the two funnels, which allows air to flow up through the 
vent passages 16 and 17. 
An overhead view of the interior funnel 11 is provided in FIG. 3. This view 
shows in phantom line the raised projections 13, wedges 14 and exterior 
funnel 12 of the self-venting apparatus 10, and emphasizes that the liquid 
being poured will only come in contact with the interior funnel 11 when 
poured therein. 
In FIG. 4, a cross sectional view is provided and shows the vent passages 
16 and 17. These vent passages 16 and 17 are generally annular and 
surround the area between the two funnels. Moreover, it can be seen that 
the wedges 14 are integrally attached to the outside of the spout 20 of 
the interior funnel 11. The wedges 14 fill-in parts of the vent passages 
16,17 and exert pressure against the inside spout 22 wall of the exterior 
funnel 12. There is still plenty of space left in the vent passages 16,17 
to allow air to flow through the vent passages 16,17. The spout 20 of the 
interior funnel 11 can be pushed down into and through the spout 22 of the 
exterior funnel 12, until the two funnels are snapped together in place. A 
hose ring (not shown) for a hose adapter can also be attached to the apex 
of the interior funnel 11. 
It is to be understood that the present invention is not limited to the 
sole embodiment described above, but encompasses any and all embodiments 
within the scope of the following claims.
