The present invention has the configuration described above, and the spring for pushing up the actuator of the conventional liquid discharge container has been removed, so that no force is required for compressing the spring when the actuator is pushed down. It can be pressed down with less force than before, and a finger hook is attached to the top of the head, so that the operator can easily move up and down by putting the fingertip of the hand holding the container on the finger hook. .come.

Furthermore, since there is no spring for pushing up the actuator, the actuator can be stopped at the lowered position when the container is not used, so that the height of the container is reduced compared to the conventional one, and compactness is achieved. You can do it. Furthermore, by providing the finger hook 30 on the upper surface of the head, the position of the finger hook relative to the head can be kept constant, and thus the finger hook for the head can be fixed. By adjusting the position, it is possible to prevent the head from being pushed or pushed back as usual, so that the head can always be pushed down almost vertically. Therefore, it is possible to prevent the liquid leakage due to the lateral pushing or the pushing.

Further, as shown in claim 2, the finger hanging portion is formed of a U-shaped flat plate having both ends pivotally attached to the left and right side surfaces of the head so that the both ends can be raised and lowered, and when the U-shaped plate is tilted forward, the plate is formed. By providing the inner surface so as to close the front surface of the nozzle, it is possible to prevent dust or the like from adhering to the nozzle and prevent the nozzle from being clogged.

By lowering the sliding cylinder, the upper part of the finger hook can be kept close to the upper surface of the head, so that the height of the whole container can be conveniently reduced.

As claimed in claim 4, the operation of the actuator can be performed by raising the auxiliary wall so that the head can move up and down along the left and right sides of the top wall from the left and right sides of the top wall of the cap-shaped member. When holding the container, the operator can operate the actuator by grasping the upper part of the container body from the lower part of the auxiliary wall, so that the position of the hand to be gripped can be made higher than when the auxiliary wall is not provided. As a result, the height when the fingertip engaged with the finger hook is raised upward can be increased, so that the stroke of the actuator can be increased and the auxiliary wall guides. This prevents the head from sticking when the head is moved up and down, thereby facilitating operation of the actuator.
