Insulated beverage holder with vertical bracket and flat storage method

A beverage holder device comprising:

• a flexible foldable cylindrically-shaped insulated sleeve with a straight longitudinal side fabric seam that includes a flexible piping or welt sewn into the straight longitudinal fabric seam and a bulbous portion of the welt being in a spaced-apart parallel relationship to said fabric seam, said piping or welt being configured so as to form a beaded edge sized to slidingly engage into an accepting bracket with a longitudinal tubular shaped furrow and a smaller channel opening running a predetermined length of said bracket wherein said channel opening is smaller in width opening than a cross-section dimension of said beaded edge portion of said piping or welt;
• a circumference of the tubular shaped furrow being larger than a radius of the beaded edge of the piping or welt so when said sleeve is joined with said bracket, said sleeve is held in a non-rigid fixed position and said sleeve moves to each side of the bracket;
• the piping or welt having a flat portion configured so that when said bulbous portion is inserted within said bracket, said flat portion extends from said bulbous portion through said channel opening to said fabric seam and is integrally attached to said sleeve by said fabric seam;
• said sleeve having an inside diameter sized to receive and hold a beverage container;
• a foldable circular bottom portion for preventing said beverage container from dropping through said sleeve, said bottom portion being attachable to said sleeve in a spaced-apart overlying relationship to a bottom edge of said sleeve to form a gap between said bottom edge and said bottom portion when said beverage container is inside said sleeve, said bottom portion further having an upwardly directed elevated portion that substantially runs diagonally across a central portion of said bottom portion to form an air gap between said bottom portion and a beverage can bottom;
• said bracket having means for mounting said bracket to a vertical surface;
• and
• said bracket having a closed bottom end and an opening at its upper end, said channel being sized to receive by sliding engagement therein said piping or welt wherein said piping or welt and said channel opening are configured such that when said piping or welt is slid into said channel starting from said channel's upper end, said sleeve is held vertically in place by said bracket.
