A knock-type propelling container, comprising: a body storing a medium therein and having a tip end opening for allowing the medium to be propelled therefrom; a propelling member (22, 24) arranged in the body so as to be slid in a forward/rearward direction of the body and capable of propelling the medium toward the tip end opening; the propelling member (22, 24) being provided with a forward/rearward extending prolongation portion which has a series of engaging-stop portions arranged at fixed intervals in the forward/rearward direction; a knock member provided in a lateral opening formed in a side portion of the body so as to be reciprocably moved with respect to the body; a detent cylinder fixedly arranged in the body in the forward/rearward direction and engaged with the propelling member (22, 24) so as to be rearward slippable relative to the propelling member (22, 24); the detent cylinder being pressedly applied by a return spring onto a taper surface formed around an inner surface of the body; a thrusting cylinder arranged in the body and always biased in a rearward direction by the return spring, which is arranged between an inner step surface of the detent cylinder and a flange portion of the thrusting cylinder, and which always biases the detent cylinder and the thrusting cylinder in a direction in which they are spaced away from each other; the thrusting cylinder being adapted to be movable forward and rearward in the body and the detent cylinder, the thrusting cylinder being adapted to be moved forward by knocking the knock member, and stoppingly engaged with the engaging-stop portions of the propelling member (22, 24) so as to be rearward slippable relative to the engaging-stop portions of the propelling member (22, 24); wherein the knock member is adapted to be reciprocably moved in a direction perpendicular to the forward/rearward direction of the body, the knock member being formed with first cam surfaces, the thrusting cylinder being formed with second cam surfaces slidable relative to the first cam surfaces, and when the knock member is knocked, the first cam surfaces and the second cam surfaces cooperate with each other, to thereby cause the thrusting cylinder to be moved forward. a body storing a medium therein and having a tip end opening for allowing the medium to be propelled therefrom; a propelling member (22, 24) arranged in the body so as to be slid in a forward/rearward direction of the body and capable of propelling the medium toward the tip end opening; the propelling member (22, 24) being provided with a forward/rearward extending prolongation portion which has a series of engaging-stop portions arranged at fixed intervals in the forward/rearward direction; a knock member provided in a lateral opening formed in a side portion of the body so as to be reciprocably moved with respect to the body; a detent cylinder fixedly arranged in the body in the forward/rearward direction and engaged with the propelling member (22, 24) so as to be rearward slippable relative to the propelling member (22, 24); the detent cylinder being pressedly applied by a return spring onto a taper surface formed around an inner surface of the body; a thrusting cylinder arranged in the body and always biased in a rearward direction by the return spring, which is arranged between an inner step surface of the detent cylinder and a flange portion of the thrusting cylinder, and which always biases the detent cylinder and the thrusting cylinder in a direction in which they are spaced away from each other; the thrusting cylinder being adapted to be movable forward and rearward in the body and the detent cylinder, the thrusting cylinder being adapted to be moved forward by knocking the knock member, and stoppingly engaged with the engaging-stop portions of the propelling member (22, 24) so as to be rearward slippable relative to the engaging-stop portions of the propelling member (22, 24); wherein the knock member is adapted to be reciprocably moved in a direction perpendicular to the forward/rearward direction of the body, the knock member being formed with first cam surfaces, the thrusting cylinder being formed with second cam surfaces slidable relative to the first cam surfaces, and when the knock member is knocked, the first cam surfaces and the second cam surfaces cooperate with each other, to thereby cause the thrusting cylinder to be moved forward.
