<P>PROBLEM TO BE SOLVED: To provide a simply structured residual amount check mechanism for a jet container which makes it possible to inform the rise of a movable bottom panel to a predetermined low residual amount position by a reduced jet amount. <P>SOLUTION: This relates to an airless pump type jet container with a movable bottom panel 20 which rises toward a cylinder 12 by negatively pressurizing the inside of the container 1 linked with the jetting of a content liquid from its nozzle by the manual operation of a jet head 9. In order to make it possible to confirm the reduction of the residual amount of the liquid, the panel 20 is provided with a cup shaped bottom panel main body 23 corresponding to the outer peripheral shape of the cylinder 12, and the outer peripheral face of the cylinder 12 is provided with a rubber tube 36 which works as an interfering elastomer by elastic compression relative to the rising movement by which the main body 23 makes the cylinder 12 invade. By this, when the panel 20 rises to a predetermined low residual amount position, the tube 36 interferes the rising movement corresponding to the negative pressure in the cylinder 12 resulting in a reduced jet amount. <P>COPYRIGHT: (C)2007,JPO&INPIT |
