It can also be configured separately. In this case, the urging member 60 is composed of, for example, a spring made of metal or resin, and is arranged inside the measuring chamber R so as to be located between the movable tubular body 50 and the inner plug body 32. be able to.

  The overcap 70 is made of, for example, a resin material and has a cylindrical shape with a top. A female screw 71 is provided on the inner peripheral surface of the peripheral wall of the overcap 70, and the female screw 71 is screwed to a male screw 12b provided on the outer peripheral surface of the mouth portion 12, whereby the overcap 70 is detachably attached to the mouth portion 12. It is attached and covers the pouring cap 20.

  An engagement portion 72 is integrally provided on the inner surface of the top wall of the overcap 70. The engagement portion 72 is formed in a tubular shape, and protrudes downward from the inner surface of the top wall of the overcap 70. Further, an annular locking concave groove 72a is provided on the outer peripheral surface on the tip side of the engaging portion 72, and the inner peripheral surface on the distal side of the plug body 41 corresponding to the locking concave groove 72a, that is, the pouring out. A locked convex portion 46 is integrally formed on the inner peripheral surface of the flow path 44.

  When the overcap 70 is attached to the mouth portion 12, the locked convex portion 46 detachably undercuts the locking concave groove 72a, and the movable plug body 40 at the pouring position is fixed to the overcap 70. It is in a detachably held state. Further, the opening of the pouring tube portion 23 is closed by the closing cylinder 73 provided on the inner surface of the top wall of the overcap 70.

  When the overcap 70 is removed from the mouth portion 12 from this state, the movable plug body 40 is held by the engaging portion 72 and pulled upward together with the overcap 70, and as shown in FIG. Move to. With such a configuration, the movable plug 40 can be easily moved from the pouring position to the weighing position by a simple operation of only removing the overcap 70 from the mouth 12. It should be noted that the movable plug 40 has its upper end portion of the skirt portion 42 brought into contact with the inner surface of the stopper portion 51 of the movable tubular body 50 in the state of being brought into contact with the lower end of the spouting tubular portion 23, whereby The stroke end on the side is defined. Further, the movable cap 40 is moved from the pouring position to the weighing position, and the overcap 70 is further pulled upward to release the engagement between the locked convex portion 46 and the locking concave groove 72a. The overcap 70 can be removed from the container body 10.

  Next, with reference to FIG. 2 and FIG. 3, a procedure for dispensing a fixed amount of the content weighed in the weighing chamber R from the fixed-quantity dispensing container 1 having such a configuration in small portions and applying it to the surface S to be coated. Will be described.

  When using the fixed-volume dispensing container 1, first, the overcap 70 is removed from the opening 12 of the container body 10. When the overcap 70 is removed from the mouth portion 12, the movable plug 40 is pulled upward by the overcap 70 to the weighing position as shown in FIG. When the movable stopper 40 reaches the measuring position, the umbrella-shaped seal 45 of the movable stopper 40 is separated from the seal cylinder portion 32a, the outflow hole 33 is opened, and the housing portion 13 of the container body 10 is communicated with the measuring chamber R.

  As shown in FIG. 2, when the movable stopper 40 is at the weighing position, the tip of the movable cylinder 50 at the protruding position is located between the tip of the pouring cylinder portion 23 and the tip of the movable stopper 40. It is like this. As a result, it is possible to prevent the movement stroke of the movable tubular body 50 in the axial direction from becoming excessively large, and to reduce the size of the quantitative dispensing container 1. In addition, when the movable stopper 40 is at the weighing position, the tip of the movable barrel 50 at the protruding position may be equal to or higher than the tip of the movable stopper 40.

  Next, as shown in FIG. 3 (a), the fixed-volume dispensing container 1 is placed in an inverted posture in which the mouth 12 is on the lower side of the body 11. As a result, the liquid content stored in the storage portion 13 of the container body 10 is filled in the measuring chamber R through the outflow hole 33. At this time, even if the liquid content filled in the measuring chamber R reaches the gap between the pouring cylinder portion 23 and the movable stopper 40, the gap is narrowed by disposing the movable cylinder 50. Therefore, the contents are held in the gap due to the surface tension and do not flow out.

  The pouring cap 20 may be formed of a transparent material so that it is possible to easily confirm that the measuring chamber R is filled with the content.

  When the measuring chamber R is filled with the contents until the measuring chamber R is fully filled, the tip of the movable stopper 40 is then pressed against the surface S to be coated with the fixed amount dispensing container 1 in the inverted posture. By the pressing force, the movable stopper 40 is moved from the measuring position to the pouring position as shown in FIG. 3 (b). When the movable stopper 40 moves to the pouring position, the outflow hole 33 is closed and a predetermined amount of content is stored inside the measuring chamber R.

  When the movable stopper 40 is moved from the measuring position to the pouring position, the tip of the movable cylinder 50 is also pressed against the surface S to be coated during the movement. Therefore, by pressing the movable stopper 40 against the surface S to be coated and moving it from the measuring position to the pouring position, the movable cylinder 50 also moves from the protruding position to the pushing position while elastically deforming the biasing member 60. Can be made.

  When the movable plug 40 is at the pouring position and the movable cylinder 50 is at the push-in position, the inflow port 44b is closed by the movable cylinder 50.

  Next, as shown in FIG. 3C, when the movable plug 40 at the pouring position is separated from the surface S to be coated, the movable plug 40 remains attached at the pouring position and the movable cylindrical body 50 is attached. The urging force of the urging member 60 moves from the pushing position to the protruding position. When the movable cylindrical body 50 moves from the pushing position to the protruding position by the urging force of the urging member 60, the inflow port 44b is opened, the measuring chamber R is communicated with the outside through the pouring channel 44, and the measuring chamber R The contents inside are poured out from the outlet 44a. Further, in a state where the fixed amount dispensing container 1 is in the inverted posture, the movable cylindrical body 50 is repeatedly pressed against the surface S to be coated and axially reciprocates between the projecting position and the pressing position to move the inflow port 44b. The contents held in the measuring chamber R and in the pouring flow path 44 are opened and closed by the cylindrical body 50, and due to the negative pressure generated in the measuring chamber R accompanying the pouring of the contents, the surface tension of the contents, and the like. The movable cylinder 50 can be guided to the outlet 44a and discharged to the outside by vibration or the like caused by the reciprocating motion or the opening / closing motion of the movable cylinder 50. As described above, according to the fixed-volume dispensing container 1 of the present invention, a fixed amount of the contents weighed in the weighing chamber R is repeatedly pressed against the surface S to be coated by the movable cylindrical body 50, so that the contents are poured into the outlet 44a in small portions. Can be issued. Therefore, by repeatedly pressing the movable cylindrical body 50 against the surface S to be coated such as the scalp while moving the coating location, the contents weighed in the weighing chamber R are dispensed in small portions from the outlet 44a to be coated. It can be applied to a wide range of the surface S.

  At this time, when the movable tubular body 50 is pressed against the surface S to be coated, the movable tubular body 50 moves from the projecting position toward the pushing position against the biasing force of the biasing member 60. The pressing force of the coating member 50 toward the coated surface S is alleviated by the elastic deformation of the urging member 60. As a result, it is possible to reduce the stimulus applied to the surface S to be coated by the movable cylindrical body 50 that is repeatedly pressed against the surface S to be coated, and to enhance the coating feeling.

  After the application of the contents is completed, the fixed amount dispensing container 1 is returned to the upright posture, and the overcap 70 is attached to the mouth portion 12, so that the locking concave groove 72a of the engaging portion 72 is formed in the movable stopper 40. The opening of the dispensing cylinder portion 23 can be closed by the closing cylinder 73 while engaging with the locked convex portion 46.

  It is needless to say that the present invention is not limited to the above-mentioned embodiment and can be variously modified without departing from the scope of the invention.

  For example, in the above-described embodiment, the fixed-volume dispensing container 1 is used for storing a liquid medicine as a content and for dispensing the content into a predetermined amount on a surface S to be coated such as a user's skin. Although it has been illustrated as the one used, specifically, it can also be used for the purpose of accommodating other contents such as a medicine, a quasi drug, a cosmetic solution, and a detergent.

  Further, in the above-described embodiment, the biasing member 60 has a thin umbrella-like structure integrally formed with the movable cylinder 50 made of synthetic resin, but the movable cylinder 50 is located at the protruding position from the pushing position. If it can be urged to, the material and the configuration can be variously changed.

  Further, the movable stopper 40 is configured to be engaged with the engaging portion 72 of the overcap 70 and moved from the pouring position to the weighing position by removing the overcap 70, but the invention is not limited to this. After the cap 70 is removed, the pouring position can be manually switched to the weighing position.
