PURPOSE:To always make the execution of steady ink jet possible, by providing the nozzle cap a part of which is at least constructed of a flexible component and otherwise by providing the nozzle cap interconnected to the container having a flexible component at least as its part. CONSTITUTION:The border between the nozzle cap 4 and the cap holder 5 and the sticking part of the flexible component 6 consisting of thin materials of rubber, high molecular material or metallic film, etc. to the cap holder 5 are completely sealed with adhesion or the like and the tops of nozzle 3 are prevented from directly exposing to the atmosphere. Thus, even though the space in the nozzle cap 4 and the space 7 of a meniscus part become of a negative pressure state or a positive pressure state because of the pressing or separation of the nozzle cap 4 and the temperature increase, the pressure variation is absorbed by the flexure of the flexible component 6 as given by the chain line and the meniscus 3 is not affected. Therefore, the always steady jetting of ink is made possible. |
