  The radial thickness of the covering tubular portion 51 and the tubular distal end portion 53 is slightly smaller than the radial interval between the outer peripheral surface of the movable plug 40 and the inner peripheral surface of the pouring cylinder 23. The contents can be prevented from flowing out of the gap between the pouring cylinder 23 and the movable plug 40 without hindering the movement of the body 40 in the axial direction. The coating tubular portion 51 and the tubular distal end portion 53 are movable alone or together with the movable plug 40 in the axial direction between the outer peripheral surface of the movable plug 40 and the inner peripheral surface of the pouring cylinder 23. In addition, if the covering cylinder part 51 can move in the axial direction between the pouring cylinder part 23 and the movable plug 40, its radial thickness dimension is equal to the outer peripheral surface of the movable plug 40 and the pouring cylinder part 23. May be made equal to the radial distance from the inner peripheral surface of the base.

  In the present embodiment, the tubular distal end 53 of the opening / closing cylinder 50 is configured to always protrude to the outside from the tip of the pouring cylinder 23 regardless of the axial movement position of the opening / closing cylinder 50. However, the present invention is not limited to this, and when the tubular distal end portion 53 of the opening / closing tubular body 50 is pushed toward the movable plug 40, the leading end thereof is positioned at the same position as the distal end of the pouring tubular portion 23. It is also possible to adopt a configuration in which it is performed. When the cylindrical tip 53 of the opening / closing cylinder 50 is configured to always protrude from the tip of the pouring cylinder 23, the opening / closing cylinder 50 is more stably turned toward the movable plug 40. You can push it.

  The overcap 60 is formed in a topped cylindrical shape by, for example, a resin material. A female screw 61 is provided on the inner peripheral surface of the peripheral wall of the overcap 60, and the female screw 61 is screwed to a male screw 12 b provided on the outer peripheral surface of the mouth portion 12, so that the overcap 60 can be detachably attached to the mouth portion 12. It is attached and covers the pouring cap 20.

  An engaging portion 62 is integrally provided on the inner surface of the top wall of the overcap 60. The engaging portion 62 is formed in a cylindrical shape, and protrudes downward from the inner surface of the top wall of the overcap 60. An annular locking groove 62a is provided on the outer peripheral surface on the distal end side of the engaging portion 62, and the inner peripheral surface on the distal end side of the plug body 41 corresponding to the locking concave groove 62a, A locked projection 46 is formed integrally with the inner peripheral surface of the flow path 44.

  In a state where the overcap 60 is attached to the mouth portion 12, the locked convex portion 46 is detachably undercut engaged with the locking groove 62a, and the movable plug 40 at the pouring position is engaged with the overcap 60. It is in a state of being detachably held. Further, the opening of the pouring tube portion 23 is closed by a closing tube 63 provided on the inner surface of the top wall of the overcap 60.

  When the overcap 60 is removed from the mouth portion 12 in this state, the movable plug 40 is held by the engaging portion 62 and pulled up together with the overcap 60, and as shown in FIG. Go to. With such a configuration, the movable stopper 40 can be easily moved from the pouring position to the measuring position by a simple operation of simply removing the overcap 60 from the mouth portion 12. In addition, the movable plug 40 has an upper end portion of the skirt portion 42 in contact with an inner surface of the stopper portion 52 of the opening / closing cylinder 50 in a state of contacting a lower end of the pouring cylinder portion 23, so that the movable stopper 40 is at its measurement position. The side stroke end is defined. Further, by further pulling up the overcap 60 from the state in which the movable plug 40 has been moved from the pouring position to the measuring position, the engagement between the locked convex portion 46 and the locking concave groove 62a is released. The overcap 60 can be removed from the container body 10.

  Next, with reference to FIGS. 2 and 3, a procedure of dispensing a predetermined amount of the content measured in the measuring chamber R from the quantitative dispensing container 1 having such a configuration into small portions and applying the content to the application surface S. Will be described.

  When using the fixed amount dispensing container 1, first, the overcap 60 is removed from the mouth portion 12 of the container body 10. When the overcap 60 is removed from the mouth portion 12, as shown in FIG. 2, the movable plug 40 is pulled up by the overcap 60 to be in the measurement position. When the movable plug 40 is at the measuring position, the umbrella-shaped seal 45 of the movable plug 40 is separated from the seal tube 32a, the outlet hole 33 is opened, and the housing 13 of the container body 10 is communicated with the measuring chamber R.

  Next, as shown in FIG. 3A, the dispensing container 1 is set in an inverted posture in which the mouth 12 is on the lower side with respect to the body 11. As a result, the liquid content stored in the storage section 13 of the container body 10 is filled into the measuring chamber R through the outflow hole 33. At this time, the stopper portion 52 of the opening / closing cylinder 50 formed of the elastic body is sandwiched between the ejection cylinder 23 and the movable plug 40 so that the gap between the ejection cylinder 23 and the movable stopper 40 is formed. Is sealed, the leakage of the contents filled in the measuring chamber R to the outside is prevented.

  It should be noted that the pouring cap 20 may be formed of a transparent material so that it can be easily confirmed that the contents have been filled in the measuring chamber R to the full amount.

  When the contents are filled in the weighing chamber R until the weighing chamber R is full, then, as shown in FIG. The tip of the cylindrical tip 53 is pressed against the surface S to be coated. When the tip of the cylindrical tip 53 is pressed against the surface S to be coated, the pressing force moves the movable plug 40 together with the opening / closing cylinder 50 from the measuring position to the pouring position. When the tip of the cylindrical tip 53 is further pressed against the surface S to be coated after the movable plug 40 is at the pouring position, the inward projection 53a of the tubular tip 53 is Until the end comes into contact with the distal end, it moves axially with respect to the plug body 41 toward the measuring chamber R along the outer peripheral surface of the plug body 41. At this time, since the movement of the coating tubular portion 51 in the axial direction is regulated by the stopper portion 52, when the cylindrical distal end portion 53 is moved in the axial direction toward the measuring chamber R, the coating tubular portion 51 is stopped by the stopper. The portion between the portion 52 and the cylindrical tip portion 53 is elastically deformed in the radially increasing direction so as to reduce the axial dimension. When the movable plug 40 is at the pouring position, at least a part of the opening / closing slit 54 is located below the lower end of the pouring cylinder 23, so that when the opening / closing slit 54 is opened in the circumferential direction, the measuring chamber is opened. R is communicated with the inflow port 44 b through the opening / closing slit 54, and the contents in the measuring chamber R are discharged from the outflow port 44 a provided at the tip of the movable plug 40 through the discharge flow path 44. Can be poured out.

  Next, as shown in FIG. 3C, when the cylindrical tip 53 is separated from the surface S to be coated, the covering cylinder 51 is opened and closed by its elastic force while the movable plug 40 is at the pouring position. The slit 54 is restored to its original shape to close, and the cylindrical distal end 53 moves to the original position where the inward projection 53 a is separated from the distal end of the movable plug 40. By repeatedly pressing the opening / closing cylinder 50 against the surface S to be coated in a state in which the fixed quantity dispensing container 1 is in the inverted posture, the inflow port 44b is opened / closed by the opening / closing slit 54, and a fixed amount of The contents can be discharged in small portions from the outlet 44a. Therefore, by repeatedly pressing the coating cylindrical portion 51 against the surface S to be coated such as the scalp while moving the coating portion, the content measured in the measuring chamber R is poured out from the outlet 44a into small portions to be coated. It can be applied over a wide area of the surface S.

  At this time, when the opening / closing cylinder 50 is pressed against the surface S to be coated, the cylindrical distal end 53 of the opening / closing cylinder 50 is elastically deformed in the radially enlarged direction so that the coating cylinder 51 reduces the axial dimension. Since it moves in the direction and is pushed into the weighing chamber R side, the pressing force of the opening / closing cylinder 50 toward the surface S to be coated is reduced by the elastic deformation of the coating cylinder 51. Thereby, the stimulus given to the application surface S by the opening / closing cylinder 50 repeatedly pressed against the application surface S can be reduced, and the application feeling can be enhanced.

  After the application of the contents is completed, the dispensing container 1 is returned to the upright posture, and the overcap 60 is attached to the mouth portion 12 so that the locking groove 62 a of the engaging portion 62 is moved to the movable plug 40. The opening of the pouring cylinder 23 can be closed by the closing cylinder 63 while being engaged with the locked projection 46.

  The present invention is not limited to the above embodiment, and it goes without saying that various changes can be made without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the fixed amount dispensing container 1 is used for storing a liquid drug as a content, and dispensing the content in small portions into a coating surface S such as a user's skin. Although illustrated as being used, specifically, it can be used for the purpose of accommodating other contents such as pharmaceuticals, quasi-drugs, cosmetic liquids, and detergents.
