Abstract:
1. 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 and a lateral opening formed in a side surface thereof; a propelling member arranged in the body so as to be slidable in a forward/rearward direction of the body and capable of propelling the medium toward the tip end opening, the propelling member being provided with a forward/rearward extending prolongation portion which includes a series of engaging-stop portions formed at fixed intervals in the forward/rearward direction; a knock member provided in the lateral opening of the body so as to be reciprocably moved in a radial direction perpendicular to an axial direction of the body; and a double cyclinder structure for converting radially inward movement of the knock member relative to the body into forward movement of the propelling member and for allowing the propelling member to propel the medium toward the tip end opening of the body, the double cylinder structure comprising a detent cylinder fixedly arranged in the body, and a thrusting cylinder arranged in the detent cylinder and always biased in a rearward direction, the propelling member being inserted through the thrusting cylinder and the detent cylinder, the thrusting cylinder being adapted to be moved forward by knocking the knock member and including first cam surfaces provided on an outer peripheral surface thereof, a first pair of elastic piece portions elastically deformable in a radical direction relative to the prolongation portion of the propelling member, each of the first pair of elastic piece portions being surrounded by slits formed in a peripheral surface of the thrusting cylinder, and a pair of thrusting pawls stoppingly engageable with the engaging-stop portions of the propelling member, each of the pair of thrusting pawls being formed at a tip end of corresponding one of the first pair of elastic piece portions, the first cam surfaces and the first pair of elastic piece portions being disposed along an axial direction of the thrusting cylinder, the knock member being formed with second cam surfaces slidingly contactable with the first cam surfaces of the thrusting cylinder, the thrusting cylinder being adapted to be moved forward by cooperation of the first and second cam surfaces when the second cam surfaces of the knock member slidingly contact the first cam surfaces of the thrusting cylinder by knocking the knock member, the detent cylinder being engageable with the engaging-stop portions of the prolongation portion of the propelling member, the prolongation portion of the propelling member being configured in such a manner that the engaging-stop portions thereof slip forward relative to the detent cylinder but do not slip rearward relative to the detent cylinder and are maintained in an engagement state with the detent cylinder, and the thrusting cylinder being configured in such a manner that the pair of thrusting pawls thereof slips rearward relative to the engaging-stop portions but does not slip forward relative to the engaging-stop portions and is maintained in an engagement state with the engaging-stop portions.
