Abstract:
A tension-actuated submerged dispenser comprising(a.) an orificed container having a shape-deformable wall structure consisting of low bending modulus and high tensile strength membraneous material, and(b.) a pair of opposed end-effectors at opposite ends of said dispenser, arranging said end-effectors vertically with respect to one another so that one of said end-effectors is a top end-effector and the other is a bottom end-effector,and wherein a tension is applied to said wall structure of said container by means of a pulling force developed between the said end-effectors, said pulling force being developed by providing that at least one of said end-effectors is both free to move and is made to execute movement in an opposite direction from the other end-effector, causing said movement by providing that the moving end-effector is of a specific gravity differentiated from that of a surrounding liquid environment of use of said dispenser.
