Manually operated liquid injection container having a finger knob

Abstract

Herein disclosed is a liquid injection container which comprises: a container body 1; a cylinder 10 depending into the container body from a cap-shaped member 3 fitted on the outer face of the mouth/neck portion of the container body; and an actuator 20 having a stem 17 erected through the top wall 4 of the cap-shaped member from a cylindrical piston 16, which is fitted in the cylinder, and a head 18 fitted on the upper end of the stem and having a nozzle opened forward. The actuator is moved up and down with respect to the cylinder for sucking a liquid in the container body into the cylinder and discharging the liquid in the cylinder out of the nozzle 19 through the stem. A finger knob 30 attached to the top face of the head for receiving a finger. The vertical movements of the actuator are accomplished by the tip of the finger inserted into the finger knob. The actuations of the actuator are facilitated through use of auxiliary walls 6 and 6 acting as a finger knob and guiding the head. These auxiliary walls are erected along the righthand and lefthand two side portions of the head.
