Abstract: An implement for applying liquid having an elastic container for containing liquid, a head cylinder connected to the elastic container, and a liquid applying member provided in the head cylinder for applying liquid to a desired application surface, the elastic container having in an opening thereof a valve assembly for supplying and blocking liquid from the elastic container to the head cylinder and pressing portions in sides thereof, the valve assembly being actuated by pressing the pressing portions, the elastic container including an oval cylindrical portion having an elliptical cross section consisting of short arcuate portions and long arcuate portions, the long arcuate portions having actuators in the form of inward projected recesses at central portions thereof, respectively, for acting as pressing portions, the valve assembly including a valve rod carrying a slide member having a tapered surface, the slide member being disposed between the two actuators.

Abstract: A propelling or automatic writing implement having a lead which can be projected from the implement without pushing. An inner frame having a chuck assembly for permitting advance of the lead but preventing retraction of the lead and a lead protecting tube having a holder for holding the lead with a suitable frictional force are housed in a main body and slidable axially thereof. A mechanism is provided for retracting the frame and the tube by a reaction to which the lead is subjected when pressed against the writing surface with a force of considerable magnitude and for returning them when the lead is released from the force, while permitting the tube to move backward and forward relative to the frame in the course of the reciprocating movement. The lead can be projected by the relative movement of the tube and the frame.
