Lined storage bin

1. A storage bin comprising:

a container comprising:

a closed base end and an opposing open top end with an elongated body therebetween, said body having an interior side and an opposing exterior side and said open top end;

a rim portion at said open top end forming the uppermost edge of said open top end and circumscribing a generally circular opening providing access to the interior of said enclosed container;

wherein said exterior side comprises a first portion disposed around said rim and having a first radius a second portion disposed between said rim and said closed base end and having a second radius larger than said first radius;

wherein said interior side has a height greater than said second portion;

a venting grommet attachable to said open top end comprising:

an outermost wall having opposing top and bottom sides and being generally in the shape of a circular major arc having two terminal ends, said outermost wall having a radius larger than the radius of said rim;

an inner wall having opposing top and bottom sides and being generally in the shape of a circular major arc the endpoints of which are connected by a chord coplanar with said terminal ends of said outer wall, said inner wall having a radius smaller than the radius of said rim and said inner wall being generally concentric with and circumscribed by said outer wall, and said inner wall and said chord defining the perimeter of a hollow center opening;

a top generally perpendicularly and terminally connected to said top side of said outer wall and said top side of said inner wall; and,

wherein said inner wall and said outer wall are about the same height;

wherein said inner wall, said outermost wall, and said hollow center opening are generally concentric;

wherein when said venting grommet is attached to said open top end of said container, said outer wall only circumscribes a portion of said rim; and

wherein when said venting grommet is rotated about ninety degrees with respect to said generally circular opening, said venting grommet can pass through said generally circular opening.

2. The storage bin as claimed in claim 1 , said storage bin further comprising:

a liner bag having an open end wherein when said liner bag is disposed upon said container such that said open end of said liner bag circumscribes said rim and when said venting grommet is attached to said container, said venting grommet holds said liner bag in place.

3. The storage bin as claimed in claim 1 , wherein said rim and said outer wall are threaded such that said venting grommet may be screwed onto said rim.

4. The storage bin as claimed in claim 1 , said storage bin further comprising:

a liner bag dispensing system comprising:

a spindle within said container having opposing top and bottom ends and an elongated body therebetween, said bottom end of said spindle attached to the center of said base end of said container;

a support within said interior having opposing top and bottom sides, said top end of said spindle being attached to said support;

wherein when a spool of liner bags is placed on said spindle, a liner bag from said spool of liner bags can pass between said support and said interior side of said container.

5. The storage bin as claimed in claim 4 , said storage bin further comprising a spool of liner bags disposed on said spindle.

6. The storage bin as claimed in claim 4 , wherein the length of said spindle is less than half the length of said enclosed container.

7. The storage bin as claimed in claim 4 , wherein said support is removable from said spindle.

8. The storage bin as claimed in claim 1 , wherein the height of said inner wall is about the same as the height of said outer wall.

9. The storage bin as claimed in claim 1 , where the radius of said rim is less than the radius of said cylindrical container.

10. The storage bin as claimed in claim 1 , wherein said venting grommet is made from plastic.

11. The storage bin as claimed in claim 1 , wherein the distance between the center of said chord and the midpoint of said major circular arc of said outer wall is greater than the radius of said rim and less than the diameter of said rim.

12. The storage bin of claim 1 , wherein the angle measure of said major arc of said inner wall is not less than 250 degrees.

13. The storage bin of claim 1 , wherein the angle measure of said major arc of said outermost wall is not less than 250 degrees.
