  • the plunger 60 includes a clicking body 61 , a piston 62 that can move forward by sliding through the tank T, a piston rod 63 having an external screw formed on an outer peripheral surface thereof, a rotation cam 64 having an internal screw that is screwed to the external screw of the piston rod 63 formed on an inner peripheral surface thereof, whereby the rotation cam 64 is screwed to the piston rod 63 to be capable of rotating relative thereto, a swing cam 65 configured to be capable of swinging in order to drive the rotation cam 64 to rotate in a single rotational direction, a top crown 66 attached to the rear end portion of the container main body 10 in order to support the plunger 60 , a return spring 67 that biases the clicking body 61 rearward, and a slide cam 68 coupled to the clicking body 61 so as to be attached to the swing cam 65 .
  • the rotation cam 64 has a frontward-projecting ratchet tooth on a front surface thereof, and a plurality of cam ridges extending in the circumferential direction are formed on a rear surface thereof.
  • the swing cam 65 has a frontward-projecting ratchet tooth on a front surface thereof, and is attached to the rotation cam 64 so that the rear surface of the rotation cam 64 engages with the ratchet tooth of the swing cam 65 , whereby the rotation cam 64 is driven in only one rotational direction.
  • the return spring 67 and an assembly of the clicking body 61 and the slide cam 68 which is biased rearward relative to the swing cam 65 by the return spring 67 , are also attached to the swing cam 65 attached to the rotation cam 64 .
  • the swing cam 65 and the slide cam 68 are attached in a mutually cam-engaged condition so that the slide cam 68 executes a reciprocating motion in the axial direction in conjunction with a reciprocating rotary motion executed by the swing cam 65 in the circumferential direction.
  • An assembly obtained by assembling the clicking body 61 , the rotation cam 64 , the swing cam 65 , the return spring 67 , and the slide cam 68 in the manner described above serves as a clicking set.
  • the clicking set is attached to the top crown 66 by being fitted into the rear end opening of the top crown 66 from the rear.
  • a plurality of cam ridges extending in the circumferential direction are formed on a front portion inner peripheral surface of the top crown 66 , and the plurality of cam ridges engage with the ratchet tooth of the rotation cam 64 so as to allow the rotation cam 64 to rotate in one rotational direction while preventing the rotation cam 64 from rotating in the other rotational direction.
  • the piston 62 is fitted to a front end portion of the piston rod 63 .
  • Contact surfaces constituted by a pair of planes extending in the axial direction are formed at 180-degree circumferential direction intervals on an outer peripheral surface of the piston rod 63 so as to divide the external screw of the piston rod 63 into two in the circumferential direction.
  • Contact surfaces are formed opposite the contact surfaces of the piston rod 63 on an inner peripheral surface of a front portion opening of the top crown 66 so as to contact the contact surfaces of the piston rod 63 .
  • the plunger 60 is incorporated into the container main body 10 by being press-fitted from the rear, whereupon the fluid F is injected into the tank T from the front of the container main body 10 and the fluid discharging body (the holder 22 ′ and the discharge pipe 28 ) is press-fitted into the container main body 10 from the front.
  • the front portion of the fluid discharging body (the holder 22 ′ and the discharge pipe 28 ) is covered by the applicator 26 ′, whereupon the front fitting 30 is fitted into the outer peripheral surface of the front end portion of the container main body 10 from the front.
  • the fluid discharging body (the holder 22 ′ and the discharge pipe 28 ) and the applicator 26 ′ are incorporated into the container main body 10 .
  • the cap 40 is fitted to the front fitting 30 from the front, whereby the fluid application container 1 ′ is assembled.
  • the discharge pipe 28 covered by the applicator 26 ′ which is formed from a soft material having the lowest hardness, is formed from a soft material having a lower hardness than the holder 22 ′, and therefore the discharge pipe 28 covered by the applicator 26 ′ can bend to an appropriate degree so to impart to the user a comfortable feeling on the skin.
  • the flocked finish 264 to the applicator 26 ′, as in this embodiment, an even more comfortable feeling on the skin can be imparted to the user.
  • the fluid F housed in the tank T is a cosmetic material, but in another embodiment, another desired fluid, such as a fluid for stationery, may be housed in the tank T and discharged.
  • the desired fluid can be applied to the application surface favorably, without damaging the application surface.
  • the fluid may be any desired liquid, gel, or the like.
