ABSTRACT:
The bladder includes two sidewall portions which are disposed opposite one another. Along a majority of the perimeter, the first and second sidewalls are joined together so as to form a body defining a containment area which is substantially enclosed by the sidewalls. One portion of each of the two sidewalls is not joined with the opposing sidewall so as to form a bladder with an opening along one portion thereof. In accordance with one aspect of the invention, the sidewalls of the bladder form a body, and a neck which extends beyond the unattached portions of the sidewalls. An opening is formed in a neck which extends from the body. The neck is open at opposing ends to thereby provide a conduit for placing fluids into the containment area of the body. To close the conduit formed by the neck portion, the neck portion is rolled toward the body. The rolled neck portion seals the opening closed and prevents liquid in the containment area from escaping out of the neck.
