Abstract

A rod-shaped object feeding container includes a cartridge unit and a knock mechanism unit. The cartridge unit includes a movable body and a female screw member. The knock mechanism unit includes a coupling member, a knock member, a spring member, a main body tube, and a rotary member. When the knock member is pressed, the knock member converts a force with which the knock member is pressed into a rotational force and causes the coupling member and the female screw member to be rotated in one direction so as to advance the movable body and the rod-shaped object. When the rotary member is rotated relative to the main body tube in an opposite direction, the rotary member causes the coupling member and the female screw member to be rotated in the opposite direction so as to retract the movable body and the rod-shaped object.

First claim

What is claimed is:

1. A rod-shaped object feeding container comprising:
a cartridge unit that has a rod-shaped object, the cartridge unit including:
a movable body that has a gripping portion configured to grip the rod-shaped object and has a male screw at an outer peripheral portion thereof, and
a tubular female screw member that has a female screw configured to be screwed to the male screw; and

a knock mechanism unit which the cartridge unit is attachable to and detachable from and which advances and retracts the rod-shaped object, the knock mechanism unit including:
a coupling member that is configured to be coupled to the cartridge unit and is synchronously rotatable with the female screw member when coupled to the cartridge unit,
a knock member capable of being pressed to advance the rod-shaped object,
a spring member that is configured to bias the coupling member and the knock member rearward,
a main body tube that houses the coupling member and the spring member, and
a rotary member that is disposed on a rear side of the main body tube, houses the knock member, and is rotatable relative to the main body tube,

wherein when the knock member is pressed, the knock member converts a force with which the knock member is pressed into a rotational force and causes the coupling member and the female screw member to be rotated relative to the movable body in one direction so as to advance the movable body and the rod-shaped object, and
wherein when pressing of the knock member is released and the rotary member is rotated relative to the main body tube in an opposite direction from the one direction, the rotary member causes the coupling member and the female screw member to be rotated relative to the movable body in the opposite direction, so as to retract the movable body and the rod-shaped object.

2. The rod-shaped object feeding container according to claim 1 ,
wherein the cartridge unit includes a tubular member that is located on a rear side of the female screw member, is synchronously rotatable with the female screw member, and is configured to be coupled with the coupling member,
wherein the tubular member has a first rib formed on an inner surface thereof and the first rib extends along an axial direction in which an axis of the tubular member extends, and
wherein the coupling member has a second rib formed on an external surface thereof and the second rib is configured to engage with the first rib in a rotational direction.

3. The rod-shaped object feeding container according to claim 2 ,
wherein the knock mechanism unit includes a tubular ratchet member that is disposed in the main body tube and houses the coupling member,
wherein the coupling member has a third rib formed on an external surface thereof and the third rib extends along an axial direction in which an axis of the ratchet member extends, and
wherein the ratchet member has a fourth rib formed on an inner surface thereof and the fourth rib is configured to engage with the third rib in the rotational direction when the coupling member and the female screw member are rotated relative to the movable body in the opposite direction.

4. The rod-shaped object feeding container according to claim 1 ,
wherein the knock mechanism unit includes a tubular ratchet member that is disposed in the main body tube and houses the coupling member,
wherein the coupling member has a third rib formed on an external surface thereof and the third rib extends along an axial direction in which an axis of the ratchet member extends, and
wherein the ratchet member has a fourth rib formed on an inner surface thereof and the fourth rib is configured to engage with the third rib in a rotational direction when the coupling member and the female screw member are rotated relative to the movable body in the opposite direction.

5. The rod-shaped object feeding container according to claim 4 ,
wherein the cartridge unit includes a leading tube, a cap attachable to and detachable from the leading tube, and a tubular member located on a rear side of the female screw member,
wherein the leading tube has a first annular recessed portion formed on an external surface thereof, and a first O-ring that is inserted into the first annular recessed portion is configured to be in close contact with an inner surface of the cap, and
wherein the tubular member has a second annular recessed portion formed on an external surface thereof, and a second O-ring that is inserted into the second annular recessed portion is in close contact with an inner surface of the leading tube.

6. The rod-shaped object feeding container according to claim 1 ,
wherein the cartridge unit includes a leading tube, a cap attachable to and detachable from the leading tube, and a tubular member located on a rear side of the female screw member,
wherein the leading tube has a first annular recessed portion formed on an external surface thereof, and a first O-ring that is inserted into the first annular recessed portion is configured to be in close contact with an inner surface of the cap, and
wherein the tubular member has a second annular recessed portion formed on an external surface thereof, and a second O-ring that is inserted into the second annular recessed portion is in close contact with an inner surface of the leading tube.
