A clicking type dispensing container that can dispense the content by pressing a crown disposed at the rear end of a barrel body, forwards in the axial direction, and has a structure, including a mechanical assembly that transforms the pressing force acting on crown by user operation into rotational force, a threaded body fixed to barrel body and a threaded rod screw-fitted into threaded body, and dispensing the content by advancing the threaded rod through the threaded body when the threaded rod is turned by the rotational force transformed by the mechanical assembly. The clicking type dispensing container can produce the rotational force without depending on spring force and cam configuration only, is constructed of a fewer number of parts and can dispense a fixed amount of the content by use of a thread. |

1. A clicking type dispensing container that can dispense the content inside a reservoir by a user operating a crown disposed at the rear end of a barrel body, and has a structure, including a mechanical assembly that transforms the pressing force acting on the crown by user operation into rotational force, a threaded body fixed to the barrel body, a threaded rod screw-fitted into the threaded body and a piston body fitted on the front end of the threaded rod, and dispensing the content by advancing the threaded rod by means of the threaded body by turning the threaded rod with the rotational force transformed by the mechanical assembly, characterized in that
the mechanical assembly for transforming pressing force into rotational force includes: a rotary body that is provided with the crown that is rotatable and restrained from axial movement relative to the rotary body, has an annular configuration having a first cam face directed forwards and a second cam face directed rearwards, and is arranged so as to be rotatable and movable in the axial direction relative to the barrel body; and, a first fixed cam face and a second fixed cam face that oppose the first cam face and second cam face, respectively, and are disposed and fixed to the barrel body with respect to the axial direction and the rotational direction, and is constructed such that at least one of the first cam face and the first fixed cam face, has a plurality of the first teeth, each having a forward-inclined slope relative to the predetermined rotational direction of the rotary body, and arranged with an identical pitch along the predetermined rotational direction, at least one of the second cam face and the second fixed cam face, has a plurality of the second teeth, each having a rearward-inclined slope relative to the predetermined rotational direction of the rotary body, and arranged with an identical pitch along the predetermined rotational direction, and in a state where the first cam face of the rotary body is put in mesh with the first fixed cam face by the pressing force, as the first cam face is guided along the forward-inclined slope of the tooth, the rotary body moves forwards and turns in the predetermined direction, whereas, as the aforementioned pressing force is released, the second cam face of the rotary body being kept in mesh with the second fixed cam face is guided along rearward-inclined slope of the second fixed cam face, the rotary body moves rearwards and turns in the predetermined direction, thereby, the threaded rod is rotated by rotation of the rotary body, wherein the piston body is integrally moved with the threaded rod in the axial direction by rotation of the threaded rod, and said rotation causes the piston body to advance inside the reservoir to dispense liquid content as the content. |
