  • Patent number: 9149830
    Abstract: A liquid replenishment system includes a dispensing vessel for holding a supply of a liquid that has an outer can and corresponding lid conjoinable to the outer can in an air-tight manner. The dispensing vessel is improved by the provision of a separate self-supporting secondary inner container removably receivable within the outer can. The container is fabricated of a material that is non-reactive with a liquid composition containing an organic semiconductor material, such as a polytetrafluoroethylene material or stainless steel.
