Reversible push-in is possible by the elasticity of In the illustrated example, the mounting cap 10 connected to the lower end of the nozzle 7 is liquid-tightly fitted to the container body neck 6 to fix the nozzle 7 to the container body 2 in a liquid-tight manner. The mounting cap 10 is fitted to the outer periphery of the mouth and neck portion 6 through appropriate locking means such as screwing, and a flange-like top plate 10b is extended from the upper end of the mounting tube 10a to the upper surface of the mouth and neck portion 6 and the back surface of the top plate 10b. The seal cylinder 11 that is further suspended is tightly fitted to the inner periphery of the mouth neck 6 to prevent leakage of the stored liquid. In addition, a large number of engaging ribs that are engaged with a plurality of circumferentially arranged locking ribs on the outer periphery of the mouth-and-neck portion 6 are provided on the inner periphery of the mounting cylinder 10a so as to rotate the mounting cap 10 relative to the container body 2. In addition, the engagement protrusion 13 provided on the inner surface of the mounting cylinder 10a is moved over and engaged with the lower surface of the locking protrusion 12 provided on the lower outer periphery of the mouth neck 6 to prevent the upper neck from coming out upward. ing.

  Further, the lower cylindrical portion 7c having a large diameter is erected upward from the inner peripheral edge of the flange-like top plate 10b, and the upper portion having a small diameter is upwardly extended through the elastic deformation wall portion 7a extending inward from the upper end edge thereof. A cylindrical portion 7b is erected. The elastic deformation wall portion 7a basically has an inward flange shape, and is elastically deformed by pressing from above the upper cylindrical portion 7b, so that the upper cylindrical portion 7b descends into the lower cylindrical portion 7c. When the pressing force is released, the thickness, material, shape, and the like are selected so that the elastic deformation wall portion 7a restores the original state by the elastic force. The upper cylindrical portion 7b has a reduced diameter at its upper end and opens a discharge port 14 therein. In the illustrated example, the mounting cap 10 and the nozzle 7 are integrally formed of a synthetic resin as the nozzle member A.

  The rod plug 8 is fitted so that the discharge port 14 is closed and can be pushed in an upwardly biased state, and is configured to communicate with the inside of the nozzle 7 by being pushed. In the illustrated example, a plurality of concave grooves 15 for discharging liquid are provided in the upper part of the peripheral surface, and a flange-like valve part 16 protruding from the outer periphery of the lower part is brought into contact with the rear surface of the cylinder wall forming the discharge port 14 for liquid-tightness.

Are integrally connected to each other and constantly biased upward. The thickness, material, shape, etc. are selected so that the force for elastically deforming the elastic plate portion 17 is sufficiently smaller than the force for elastically deforming the elastic deformation wall portion 7a.

  Further, the valve plate 9 closes the base end opening of the lower cylindrical portion 7c of the nozzle 7 so that the peripheral portion is slidably fitted to the inner periphery of the nozzle 7, and a measuring chamber R is defined thereabove. Yes. Further, the upper cylinder portion 7b is connected to be able to move integrally. In the illustrated example, the peripheral edge is lowered in a tapered shape, and its outer peripheral surface is fitted in a liquid-tight and slidable manner to the lower peripheral edge of the inner periphery of the lower cylindrical portion 7c, and is fitted to the inner peripheral edge of the upper cylindrical portion 7b. The lower end portion of the connecting tube 19 extending downward from the fitting tube 18 is integrally connected to the central portion of the upper surface of the valve plate 9 so that the upper tube portion 7b and the valve plate 9 can be integrally moved. Further, a window hole 20 is formed in the connecting cylinder 19 so that the inside and the outside communicate with each other. When the upper cylindrical portion 7b is pushed downward while elastically deforming the elastic deformation wall portion 7a, the valve plate 9 is moved downward so that the inside of the container body 2 and the inside of the measuring chamber R communicate with each other. Yes. Further, a plurality of radial guide ribs 21 in the circumferential direction are provided on the valve plate 9 on the outer side of the connecting cylinder 19, and the outer peripheral edge is slidably contacted with the inner peripheral surface of the nozzle 7 so that the valve plate 9 is in the nozzle 7. It is configured to perform guidance when it deviates from the circumference. In the illustrated example, the rod plug 8, the elastic plate portion 17, the fitting cylinder 18, the connecting cylinder 19, the valve plate 9 and the guide rib 21 are integrally formed of synthetic resin as an internal member B.

  The cap 4 covers the rod plug 8 and is detachably fitted to the upper cylindrical portion 7b. In the illustrated example, the top wall 23 extends from the upper end edge of the peripheral wall 22 screwed to the outer periphery of the upper cylindrical portion 7b, and the seal cylinder portion 24 suspended from the back surface of the top wall 23 forms a discharge port 14. It is constructed by fitting fluid tightly around the wall periphery.

  In using the quantitative application container 1 configured as described above, after the container is inverted from the state of FIG. 1, the top surface of the cap 4 is brought into contact with an appropriate pressing surface 25 and the container body 2 is pushed down. As shown in FIG. 2, the elastic deformation wall portion 7a is elastically deformed, and the upper cylinder portion 7b is partially pushed into the lower cylinder portion 7c. Accordingly, the valve plate 9 is detached from the lower cylinder portion 7c, and the container body 2 and the measuring chamber R communicate with each other, and the liquid in the container body 2 flows into the measuring chamber R. Next, when the pressing of the container body 2 is released, the elastic deformation wall portion 7a is restored, the container body 2 and the measuring chamber R are isolated, and a predetermined amount of liquid is measured in the measuring chamber R. Next, when the cap 4 is removed and the tip is brought into contact with the coating surface 26 and pressed as shown in FIG. 3, the rod plug 8 is pushed in and the measured liquid is applied to the coating surface 26 through the concave groove 15. The

  FIG. 4 shows another embodiment, and shows an example in which the cylindrical wall of the nozzle 7 constituting the measuring chamber R is formed transparently and a scale is provided there. In the illustrated example, the members constituting the mounting cap 10 and each nozzle 7 are made of a transparent material, and the scale 27 is formed on the lower cylindrical portion 7c. In this case, several stages of amounts can be discharged. Other configurations are the same as those of the embodiment of FIG.
