Abstract

A dispensing vessel for holding a supply of a liquid includes an outer can and corresponding lid conjoinable to the outer can in an air-tight manner 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.

Claims

1. A dispensing vessel for holding a supply of a liquid composition containing an organic semiconductor material for deposit onto a surface, the dispensing vessel having:

a outer can and corresponding lid, the lid being conjoinable to the outer can in an air-tight manner, when conjoined the can and lid cooperating to define an enclosed chamber;

wherein the improvement comprises;

a separate self-supporting secondary inner container removably receivable within the outer can, the container having a top portion and a closed bottom portion, the closed bottom portion having an outlet port defined therein,

the container being fabricated of a material that is non-reactive with a liquid composition containing an organic semiconductor material.

3. The dispensing vessel of claim 1 wherein the container is fabricated from stainless steel.

4. The dispensing vessel of claim 1 wherein the closed bottom portion of the container is conical in shape, with the outlet port being disposed at the apex of the cone.

5. The dispensing vessel of claim 4 wherein the container further includes a support skirt for supporting the container within the outer can,

the skirt connected to the top portion and disposed in surrounding relationship to the conical bottom portion.

6. The dispensing vessel of claim 5 wherein the container further comprises a cover receivable over the top portion of the container thereby to close the same in a non-air-tight manner such that the container is in fluid communication with the interior of the outer can.

2. The dispensing vessel of claim 2 wherein the container is fabricated from a polytetrafluoroethylene material.
