The inner cap 44 moves inside the container body 1 by the compressed air supplied from the compressed air supply pipe 26 into the container body 1, and thus generates a force for pushing the printing material toward the bottle opening 2.

[0019]

According to the present invention described above, the operation of supplying printing material, which has a high viscosity and takes a long time to transfer from a container to a printing material tank or the like, is greatly simplified, and the work efficiency of screen printing and the like is reduced. Can be improved. In addition, since the screen printing apparatus can be used in connection with the squeegee apparatus without being transferred to the royalties tank, the configuration of the screen printing apparatus can be simplified.

Further, since the remaining amount of the printing material in the container body can be measured by the magnetic body fixed to the inner cap and the magnetic sensor fixed to the outer peripheral surface of the container body, it is necessary to supply the printing material during printing. It is possible to eliminate scandals such as interruption of work due to the fact that the printing is performed with high accuracy, and to execute high-precision printing.
