Abstract

<P>PROBLEM TO BE SOLVED: To provide a cosmetic material applicator allowing a user to easily adjust the quantity of the cosmetic material to be applied and to apply the cosmetic material very quickly and highly efficiently. <P>SOLUTION: A pusher member 10 is moved in the axial direction within an outer barrel 60. At the time, a recess 25 is engaged with a projection formed on the rear wall of the pusher member 10, so that a center member 20 is not rotated. As a result, a pin 32 is engaged with a helical groove 24 formed in a guide part 23 of the center member 20, and a rotary cylinder 31 is rotated. As the rotary cylinder 31 is rotated, a rotary part 41 and an attaching part 70 of a brush 80 are also rotated. When the pressure by the pusher member 10 is released, the engagement between the recess 25 and the projection is released and the center member 20 retreats while rotating. In this way, the brush is rotated always in one direction with the reciprocation of the pusher member 10 in the axial direction. <P>COPYRIGHT: (C)2010,JPO&amp;INPIT

The pin 64 enters the groove 13 of the pressing member 10, so that the pressing member 10 moves relative to the outer cylinder 60 in the axial direction but does not rotate. It has become.

  On the other hand, the other end portion 62 of the outer cylinder 60 is not formed with a wall but is an open end portion. The inner diameter of the open end portion 62 is that of the flange 34 of the fixed portion 33 of the inner rotating member 30. Smaller than diameter. That is, the support portion 33 a of the fixed portion 33 has a diameter slightly smaller than the inner diameter of the outer cylinder 60, and can be inserted into the outer cylinder 60 at the open end 62. On the other hand, the flange 34 has the same diameter as the outer diameter of the outer cylinder 60, and the open end 62 of the outer cylinder 60 contacts the flange 34. The relatively large hole 63 on the peripheral surface of the outer cylinder 60 is used when operating or assembling members in the outer cylinder 60.

  Each component configured in this way is assembled as follows. The guide portion 23 of the center member 20 is inserted into the rotating cylinder 31 of the inner rotating member 30 and the pin 32 is inserted into the spiral groove 24. On the other hand, in the state where the pin 39 formed on the end surface of the connecting member 37 is inserted into the hole 45 of the outer rotating member 40, the fixing member 50 is applied from behind the outer rotating member 40, and the screw 51 of the fixing member 50 is attached. The outer rotating member 40 and the inner rotating member 30 are connected by being screwed to the screw 35 of the fixing portion 33. Therefore, the rotating cylinder 31 and the connecting portion 37 of the inner rotating member 30 and the rotating portion 41 of the outer rotating member 40 are supported rotatably with respect to the fixing portion 33 and the fixing member 50. The rotating part 41 is urged in a direction away from the fixed part 33 by a spring 43, and the rotating cylinder 31 is urged in a direction away from the fixed part 33 by a spring 36.

  On the other hand, the center member 20 is inserted into the storage portion 12 of the pressing member 10. Then, the rod-like portion 21 is inserted into the central hole 15 of the central member 10, and among the concave portions 25 formed in the flange 22, the two concave portions 25 having a central angle of 180 ° are inserted into the back of the storage portion 12. The flange 22 is brought into contact with the inner wall of the storage portion 12 in a state in which the two protrusions formed on the wall of the storage portion 12 are fitted. Thereafter, the outer cylinder 60 is externally fitted to the pressing member 10 from the open end 62 thereof, and the operation portion 11 of the pressing member 10 is protruded outward from the hole 61 of the outer cylinder 60, and the open end of the pressing member 10 is 62 is brought into contact with the flange 34 of the fixing portion 33. In this state, the outer cylinder 60 is fixed to the fixing portion 33 by means such as screwing. Then, the screw of the connecting portion 44 is screwed into the screw hole 71 of the mounting member 70 to connect the mounting member 70 to the outer rotating member 40. Thereafter, the brush 80 is attached to the attachment member 70. Thereby, as shown in FIG. 2, each member is connected and the applicator 100 is assembled.

  Next, operation | movement of the applicator 100 of this embodiment comprised as mentioned above is demonstrated. The outer cylinder 60 is held by hand, and the operation unit 11 is pushed in with a finger. Then, the pressing member 10 is pushed in the axial direction of the outer cylinder 60 without rotating relative to the outer cylinder 60. At this time, the center member 20 also moves in the pressing direction by the operation unit 11 without rotating relative to the pressing member 10 because the protrusion 14 of the pressing member 10 is fitted in the recess 25. Then, since the pin 32 is engaged with the spiral groove 24 formed on the peripheral surface of the guide portion 23, the rotary cylinder 31 of the inner rotary member 30 provided with the pin 32 rotates in one direction. When the rotating cylinder 31 rotates in one direction, the rotating portion 41 of the outer rotating member 40 also rotates in the one direction by the same angle as the rotating cylinder 31. Thereby, the brush 80 attached to the attachment part 70 also rotates.

  Then, the force which pushes in the operation part 11 of the press member 10 is cancelled | released, and the operation part 11 is made free. Then, the pressing member 10 moves (retreats) in the axial direction with respect to the outer cylinder 60. At this time, the pressing force of the center member 20 pressed against the inner wall of the storage portion 12 of the pressing member 10 by the spring 36 is reduced, and the recess 25 provided in the flange 22 of the center member 20 and the pressing member 10 are stored. The engagement with the projection 14 provided on the back wall of the portion 12 is released. Further, the center member 20 tries to move (retreat) in the same direction as the pressing member 10 by the spring in the rotating cylinder 31. On the other hand, since the pin 32 of the rotating cylinder 31 of the inner rotating member 30 is engaged in the spiral groove 24 of the guide portion 23 of the center member 20, the guide member 23 is moved to the pin 32 and the spiral groove by the retreat of the center member 20. Rotate around its central axis by engagement with 24. Therefore, the central member 20 moves backward while rotating around the central axis. The pressing member 10 is retracted until the storage portion 12 comes into contact with the wall 65 of the outer cylinder 60 and the operation portion 11 protrudes from the outer cylinder 60.

  At this time, the flange 22 is in contact with the back wall of the storage portion 12 by the spring 36 and the spring in the rotary cylinder 31, but the protrusion 14 on the back wall of the storage portion 12 is formed on the flange 22 by the rotation of the flange 22. Of the eight recesses 25, the other recesses 25 shifted by the rotation of the flange 22 are engaged.

  In this state, when the operation unit 11 is pushed in again, the central member 20 is pushed into the rotary cylinder 31 as described above, and the central member 20 does not rotate due to the engagement between the protrusion 14 and the concave portion 25. 31 and the rotating part 41 rotate in the one direction, and the brush 80 also rotates in the one direction. Thereafter, when the pressing of the operation portion 11 is released, the engagement between the protrusion 14 and the concave portion 25 is released, and the pressing member 10 moves backward without rotating, but the center member 20 is rotated by the pin 32 in the rotational direction position of the spiral groove 24. Therefore, the rotating cylinder 31 and the brush 80 do not rotate.

  In this way, by repeatedly pushing and releasing the operation unit 11, the rotating cylinder 31, the rotating unit 41, and the brush 80 always rotate in the one direction. Therefore, by applying a cosmetic material to the brush portion of the brush 80, the cosmetic material is applied to the eyelashes or the like.

  In this way, by repeating the operation of pushing in the operation unit 11 and the operation of releasing it, the axial movement and the axial retreat and rotation of the center member 20 are repeated and attached to the pedestal 60 fixed to The application of the decorative material is repeatedly performed when the brush 90 rotates in one direction.

  At the time of applying the decorative material, the rotational speed of the brush 80 can be finely adjusted by adjusting the pushing force of the operation unit 11, and a desired amount of the decorative material can be applied at a desired position. For example, by holding the mascara on the brush 80 and pressing the operation unit 11 little by little against the outer tube 60 when it is applied to the eyelashes, the new brush surface and the eyelashes always come into contact with each other. It is possible to prevent the formation of lumps or uneven coating while applying the coating. Further, if the operation unit 11 is pushed into the outer cylinder 60 at a high speed, the amount of the cosmetic material applied to the eyelashes can be reduced. And in this invention, since the brush 80 always rotates to a fixed direction, it can implement continuously, without stopping application | coating of the cosmetics with respect to eyelashes. For this reason, according to the present invention, it is possible to apply the cosmetic material very quickly and with high efficiency.
