Detachable Funnel For Water Bottles

Abstract

A detachable funnel apparatus for use with a container has an open wide end, an open narrow end, and sidewalls connecting the open wide end to the open narrow end whereby materials poured into the open end pass through the sidewalls and out the open narrow end when the detachable funnel apparatus is coupled to the container. The funnel is configured to removably affix to the container when stored by a coupling mechanism on the inside of the funnel such as a ring snap to create a snap connection between the funnel and a neck ring on the container or threads to connect to the threads on the container normally used by the cap of the container.

1 . A detachable funnel apparatus for use with a container, the container having a cap, with a closed end and a open end on top, removably attached to of the container for maintaining liquids in the container, the apparatus comprising:
 an open wide end;   an open narrow end; and   sidewalls connecting the open wide end to the open narrow end whereby materials poured into the open end pass through the sidewalls and out the open narrow end when the detachable funnel apparatus is coupled to the container;   wherein the sidewalls have an inner and outer side and include:
 a stem section proximate to the open narrow end and configured to be sufficiently narrow so that the cap may not pass though and is stopped by the top of stem section; 
 a mouth section proximate to the open wide end and configured to be sufficiently wide to allow that the cap of the container and top portion the container to pass through the open wide end; 
 a middle section located between the stem section and the mouth section configured to be sufficiently wide to allow that the cap of the container to pass through the middle section; and 
 a coupling mechanism on the inner side of the sidewalls in the middle section configured to detachably affix the apparatus to the container. 
   
   
   
       2 . The apparatus of  claim 1 , wherein the coupling mechanism is a ring snap configured to create a snap connection between the apparatus and a neck ring on the container. 
   
   
       3 . The apparatus of  claim 2 , wherein the ring snap is located on the middle section such that the distance between the ring snap and intersection of the middle section and the stem section is approximately but no less than the distance from the closed end of the cap to just below the neck ring.
