In this case, the urging member 60 is made of, for example, a metal or resin spring, and is arranged inside the measuring chamber R so as to be positioned between the movable cylinder 50 and the inner plug main body 32. be able to.

  The overcap 70 is formed in a cylindrical shape with a resin material, for example. 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 12 b 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 engaging portion 72 is integrally provided on the inner surface of the top wall of the overcap 70. The engaging portion 72 is formed in a cylindrical shape and protrudes downward from the inner surface of the top wall of the overcap 70. Further, an annular locking groove 72a is provided on the outer peripheral surface on the distal end side of the engaging portion 72, and the inner peripheral surface on the distal end side of the plug body 41, that is, the dispensing, corresponding to the locking groove 72a. A locked convex portion 46 is integrally formed on the inner peripheral surface of the flow path 44.

  In a state where the overcap 70 is attached to the mouth portion 12, the locked convex portion 46 is detachably undercut engaged with the locking concave groove 72 a, and the movable plug body 40 at the pouring position is attached to the overcap 70. The state is held so as to be detachable. Further, the opening of the dispensing cylinder 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 40 is held by the engaging portion 72 and pulled upward together with the overcap 70, and as shown in FIG. Move up to. With such a configuration, the movable stopper 40 can be easily moved from the dispensing position to the measuring position by a simple operation of simply removing the overcap 70 from the mouth portion 12. Note that the movable plug body 40 has an upper end portion of the skirt portion 42 abutting against the inner surface of the stopper portion 51 of the movable cylinder body 50 in a state of abutting against the lower end of the dispensing cylinder portion 23, thereby The stroke end on the side is defined. Further, when the movable plug 40 is moved from the pouring position to the measuring position, the overcap 70 is further lifted 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, referring to FIGS. 2 and 3, a procedure for dispensing a predetermined amount of the content weighed in the measuring chamber R from the quantitative dispensing container 1 having such a configuration and applying it to the application surface S. Will be described.

  When using the quantitative dispensing container 1, first, the overcap 70 is removed from the mouth 12 of the container body 10. When the overcap 70 is removed from the mouth portion 12, as shown in FIG. 2, the movable plug 40 is pulled upward by the overcap 70 to be in the measuring position. When the movable stopper 40 is in 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 accommodating portion 13 of the container body 10 is communicated with the measuring chamber R.

  As shown in FIG. 2, when the movable plug 40 is in the measuring position, the tip of the movable cylinder 50 in the protruding position is located between the tip of the dispensing cylinder 23 and the tip of the movable plug 40. It is like that. Thereby, it can prevent that the moving stroke to the axial direction of the movable cylinder 50 becomes large too much, and this fixed quantity dispensing container 1 can be reduced in size. In addition, when the movable plug body 40 is in the measuring position, the distal end of the movable cylindrical body 50 in the protruding position may be configured to be equal to or above the distal end of the movable plug body 40.

  Next, as shown to Fig.3 (a), let the fixed_quantity | dispersion_dispersion container 1 be an inverted posture in which the opening | mouth part 12 becomes the downward side with respect to the trunk | drum 11. FIG. Thereby, the liquid content accommodated in the accommodating portion 13 of the container body 10 is filled into 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 dispensing cylinder portion 23 and the movable stopper 40, the gap is narrowed by the movable cylinder 50 being arranged. Therefore, the contents are held in the gap by the surface tension and do not flow out.

  In addition, in order to make it easy to confirm that the weighing chamber R is fully filled with the contents, the dispensing cap 20 can be formed of a transparent material.

  When the measuring chamber R is filled with the contents until the measuring chamber R is full, next, the tip of the movable stopper 40 is pressed against the surface S to be coated while the quantitative dispensing container 1 is in the inverted posture. By the pressing force, the movable stopper 40 is moved from the measuring position to the dispensing position as shown in FIG. When the movable plug 40 moves to the pouring position, the outflow hole 33 is closed, and a predetermined amount of contents are accommodated in the measuring chamber R.

  Further, when the movable plug 40 is moved from the measuring position to the dispensing position, the tip of the movable cylinder 50 is also pressed against the application surface S during the movement. Therefore, by moving the movable plug 40 against the surface S to be coated and moving from the measuring position to the dispensing position, the movable cylinder 50 is also moved from the protruding position to the pushing position while elastically deforming the biasing member 60. Can be made.

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

  Next, as shown in FIG. 3 (c), when the movable plug body 40 in the dispensing position is pulled away from the surface S to be coated, the movable cylinder 50 is attached while the movable plug body 40 remains in the dispensing position. The urging force of the urging member 60 moves from the pushing position to the protruding position. When the movable cylinder 50 is moved from the pushing position to the protruding position by the urging force of the urging member 60, the inflow port 44b is opened, and the measuring chamber R is communicated to the outside via the pouring channel 44. The contents inside are poured out from the outlet 44a. In addition, with the quantitative dispensing container 1 in the inverted position, the movable cylinder 50 is repeatedly pressed against the surface S to be coated and reciprocated in the axial direction between the protruding position and the pressing position, thereby moving the inlet 44b. The contents held in the measuring chamber R or the extraction flow path 44 by the negative pressure generated in the measuring chamber R or the surface tension of the contents when the contents are poured out are opened and closed by the cylinder 50. The movable cylinder 50 can be guided to the outlet 44a by the vibration generated by the reciprocating movement or the opening / closing operation of the movable cylinder 50 and can be poured out. As described above, according to the quantitative dispensing container 1 of the present invention, a fixed amount of contents measured in the measuring chamber R is poured into the sub-portion from the outlet 44a by repeatedly pressing the movable cylinder 50 against the surface S to be coated. Can be issued. Therefore, the movable cylinder 50 is repeatedly pressed against the surface to be coated S such as the scalp while moving the application location, so that the contents measured in the measuring chamber R are poured out from the outlet 44a in small portions. It can be applied to a wide range of the surface S.

  At this time, when the movable cylinder 50 is pressed against the surface S to be coated, the movable cylinder 50 moves from the protruding position toward the pushing position against the urging force of the urging member 60. The pressing force toward the application surface S of 50 is alleviated by the elastic deformation of the urging member 60. Thereby, the irritation | stimulation which the movable cylinder 50 pressed repeatedly on the to-be-coated surface S gives to the to-be-coated surface S can be reduced, and the coating feeling can be improved.

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

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, in the above-described embodiment, the quantitative dispensing container 1 accommodates a liquid medicine as the contents, and is used for dispensing the contents into the application surface S such as the user's skin in small amounts. Although illustrated as what is used, specifically, it can also be used for containing other contents such as pharmaceuticals, quasi drugs, cosmetic liquids, and detergents.

  In the embodiment, the urging member 60 has a thin umbrella-like structure formed integrally with the movable barrel 50 made of synthetic resin, but the movable barrel 50 protrudes from the pushing position. If it can be energized, its material and configuration can be variously changed.

  Furthermore, the movable plug 40 is configured to be engaged with the engaging portion 72 of the overcap 70 and moved from the dispensing position to the measuring position by removing the overcap 70. After removing the cap 70, it can also be set as the structure which can be switched manually from a pouring position to a measurement position.
