There is provided a knock-type propelling container having a simple structure that allows media used in the fields of cosmetics, writing, correcting, medical treatment (dental surgery), industry, etc., to be propelled by knocking a knock member of the propelling container. The propelling container comprises a body (12) storing a medium therein and having a tip end opening (12a) for allowing the medium to be propelled therefrom, a piston (22) arranged in the body (12) so as to be slid in a forward/rearward direction of the body (12) and capable of propelling the medium toward to the tip end opening, a piston rod (24) connected to the piston (22) and having a series of engaging-stop portions (24d) formed at fixed intervals in the forward/rearward direction, a knock member (20) provided at the body (12) so as to be reciprocably moved with respect to the body (12), a thrusting cylinder (28) arranged in the body (12) and always biased in a rearward direction, the thrusting cylinder (28) being adapted to be moved forward by knocking the knock member (20) and adapted to be stoppingly engaged with the engaging-stop portions (24d) so as to be rearward slippable relative to the engaging-stop portions (24d), and a detent cylinder (26) fixedly arranged in the body (12) in the forward/rearward direction and adapted to be stoppingly engaged with the engaging-stop portions (24d) so as to be rearward slippable relative to the engaging-stop portions (24d).

The invention relates to a liquid supply device utilizing a rotating cam mechanism for supplying a liquid. In the liquid supply device for smoothly supplying a liquid with the assistance of pressurizing action, switching operation by the rotating cam mechanism can be carried out reliably. A liquid housing tube 14 housing a liquid is disposed to be movable in an axial direction in an outer shaft and has a tip end chip 32 movable between a protruding position from a tip end of the outer shaft and a retracting position in the outer shaft. A rotating cam mechanism 16 which can move the liquid housing tube 14 forward and backward includes a rotating cam 40 movable between a front position and a rear position and a pressurizing space 18 to be compressed to be able to pressurize an inside of the liquid housing tube 14 when the tip end chip 32 is in the protruding position is provided in a rear portion in the rotating cam 40.

A lead cartridge that is provided with a tank part for storing leads and is capable of being detachably connected to a receiving part provided in a lead feeding mechanism of a mechanical pencil to supply a lead can reduce costs for manufacturing the lead cartridge and the number of manufacturing steps and can prevent a lead from falling out from the lead cartridge inadvertently. The lead cartridge 10 includes a case 12 and a swing cover 14. A tank part 12a is defined inside the case 12 and the tip end part of the case 12 is formed with an open tip end connection part 12b. Between the tank part 12a and the tip end connection part 12b, a lead port 12e is formed. The swing cover 14 is mounted in the case 12 swingably to a closing position where the swing cover 14 closes the lead port 12e and to an opening position where the swing cover 14 opens the lead port 12e. The swing cover 14 includes an interfered part 14c capable of being interfered with an interference part 46e of a cartridge receiving part 46b of the mechanical pencil. The swing cover 14 is biased in a swing direction from the opening position to the closing position but swings from the closing position to the opening position when the tip end connection part 12b is fitted with the cartridge receiving part 46b so as to cause the interfered part 14c to be interfered with the interference part 46e.

A liquid applying tool is provided which can create pressurizing action with a simple structure and without any labor at the time of using the liquid applying tool, and allows liquid to be smoothly fed to a tip end of a liquid applicator member with the assistance of the pressurizing action. The liquid applicator comprises a liquid storage container 13 having liquid L stored therein and a liquid applicator member 15 provided at a tip end portion thereof, an outer container 12, the liquid storage container 13 being housed in the outer container 12 with at least a tip end of the liquid applicator member 15 being exposed to an outside of the outer container, a cap 20 removably attached to a tip end portion of the outer container 12 to cover the tip end of the liquid applicator member 15, a compression member 40 arranged in the outer container 12 and provided at a rear end portion of the liquid storage container 13, a forward biasing member 62 for causing the compression member to be biased axially forward, and a power transmitting member 60 provided in the outer container 12. The power transmitting member 60 is adapted to be reciprocation-moved in the axial direction in the outer container 12 according to attaching/detaching of the cap 20, whereby the compression member 40 is reciprocation-moved with respect to the liquid storage container 13 in the axial direction.
