## Title
Adapter for use with a funnel

## Abstract

An adapter is shown for use with a funnel having an upper tapered section and a lower tapered section and a container having a top surface with an opening therein. The adapter has a housing having a top, a bottom, a longitudinal axis, a tapered opening is disposed through the inside housing about the longitudinal axis and an outside portion, the tapered opening being larger at the top thereof than at than at the bottom for telescopically receiving the lower tapered section of the funnel.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to the use of funnels for transferring liquid from one container to another and more particularly to an adapter for facilitating an easier transfer of the liquid while using a funnel.
2. Description of the Prior Art
Funnels typically have an upper frusto conical portion and a lower frusto conical portion, the lower portion of which is thinner than the upper one. When this lower portion of the funnel is placed into a container in a situation wherein the opening in the container is larger than the lower tapered portion of the funnel, the funnel will not be properly restrained and hence can move around during the transfer of liquid from one container, through the funnel, to another container, for example as shown in FIG. 6.
Another problem with prior art funnels is that when they seal against the top opening of a container, the air will be pushed out of the container and up past the funnel as fluid is being transferred. This action slows the effective transfer of the liquid. Accordingly, there is a need to overcome the aforementioned deficiencies of the prior art.
SUMMARY OF THE INVENTION
The present invention relates to an adapter for use with funnels so that various funnel sizes can be used in containers with various sizes of openings therein and still be stable. An adapter which has multiple step portions thereon can be placed into containers of different sizes so that the adapter will remain stable on the top of the container, i.e. will not shift around. At the same time, a funnel of various sizes can be used to extend into the adapter.
Additionally, a vent structure is provided to use as an air bleed to prevent “burping” of air up past the adapter and funnel during the transfer of liquid from one container, through the funnel and adapter, to another container.
An object of the present invention is to provide an adapter which is useful for various-sized containers and various-sized funnels.
Another object of the present invention is to provide an adapter which has a built-in venting or air bleed structure.
Other objects, advantages, and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.

DESCRIPTION OF THE BEST MODE
Referring now to the drawings, where like reference numbers designate identical or corresponding views throughout the several views, FIG. 1 shows a funnel adapter 10 constructed in accordance with the present invention.
An adapter 10 is shown for use with a funnel 11 having an upper tapered section 1a and a lower tapered section 11b and a container 12 or 112 having a top surface 12a, 112a with an opening 12b or 112b respectively therein. The adapter 10 has a housing 10a having a top 10b, a bottom 10c, a longitudinal axis 10d, a tapered opening 10e is disposed through the inside housing 10a about the longitudinal axis 10d and an outside portion shown as the outside of at least part of parts 10f, 10g, or 10h, said tapered opening 10e being larger at the top thereof than at than at the bottom for telescopically receiving the lower tapered section 11b of the funnel 11.
An upper portion 10f of the housing 10a is disposed radially outwardly farther from the longitudinal axis 10d than a lower portion 10h of the housing 10a is spaced outwardly from the longitudinal axis 10d. 
An intermediate portion 10g of the housing 10a is disposed outwardly farther from the longitudinal axis 10d than is the lower portion 10h of the housing 10a but intermediate portion 10g is does not extend radially outwardly more than the upper portion 10f extends outwardly from the longitudinal axis 10d. 
A lower part 10i of the upper portion 10f has a first shoulder 10i thereof thereon for abutment with the top surface 12a of the container 12 shown in FIGS. 5 and 6 if the opening 12b in the top surface 12a of the container 12 is smaller than the top portion 10f but larger than the lower and intermediate portions 10h and 10g respectively of the housing 10a. 
The intermediate portion 10g has a second shoulder 10j thereon for abutment with the top surface 112a of the container 112 if the opening 112b in the top surface of the container 112 is smaller than the lower portion 10h of the housing 10a but larger than the lower portion 10h of the housing 10a. 
The outside of the intermediate portion 10g of the housing 10a is, in a preferred embodiment, substantially circular in shape and is smaller in diameter at the bottom thereof than at the top thereof.
The outside of the lower portion 10h of the housing 10a is, in a preferred embodiment, substantially circular in shape and is smaller in diameter at the bottom thereof than at the top thereof.
A vent passageway 10k extends through the housing 10a from the bottom thereof to the top thereof for allowing air to escape there through from the container 12 or 112 to atmosphere as liquid is poured into the container 12 or 112 through the funnel 11 and the adapter housing 10a. This prevents “burping” of air out the top of the container 12 or 112 as will happen if no vent is provided.
The vent passageway, in the preferred embodiment, extends the entire way from the tapered opening 10e radially outwardly to the outside of the housing 10a from top to bottom.
It is also noted that the adapter, in its preferred embodiment, extends around the longitudinal axis 10d by less than 360 degrees, whereby a vent passageway 10k is formed between an interior portion of the container 12 or 112 and atmosphere.
Obviously many modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
