ABSTRACT:
An evaporation closure is disclosed. One embodiment of the closure includes a cap, made of pliable material, which in turn includes a top wall having an opening, a skirt downwardly depending from the top wall and having a threadless internal wall adapted to slip on and sealingly engage a container, and biasing means integral with the skirt; and an elongated arm, which in turn includes a means for sealing the opening, pivotally attached to the cap for movement between a first position wherein the sealing means seals the opening and a second position wherein the sealing means does not seal the opening, the arm being biased toward the first position by the biasing means. Such a closure is useful for minimizing evaporation from containers, particularly automated clinical analyzer reagent bottles.
