Description of the Related Art Japanese Utility Model Application Laid-Open No. 7-2252 comprises a container having an elastically squeezable body, and a measuring instrument having a lower cylindrical portion fitted to the mouth and neck of the container. A partition wall is laid laterally on the inner surface of the tubular portion fitted to the mouth and neck, and a pipe is pierced in the center of the partition wall, and the lower cylindrical portion is extended higher than the upper end of the pipe to measure. When the container is squeezed, the liquid in the container enters the measuring cylinder through the pipe. Also, the upper liquid is sucked back into the container body by the elastic recovery of the trunk portion, and a fixed amount of liquid remains in the measuring cylinder and is measured.

来なかった。The above-mentioned container is provided so that when the pressure inside the container is increased by squeezing the body of the container, the liquid enters the measuring cylinder through a pipe hanging down into the container. It is convenient when viscosity is poor,
As the viscosity increases, it becomes more difficult for the liquid to flow through the pipe into the measuring cylinder. Also, since the liquid excessively discharged into the measuring cylinder is sucked back by elastic restoration of the body and measured, the outside air enters the container body at the time of sucking back, and it is necessary to prevent the stored liquid from being oxidized. Could not be used.

ある。According to the present invention, a lower cylinder portion is fitted to the mouth and neck of a tube container body to erect a main cylinder member, and discharge valves are provided above and below the main cylinder member. When the inside of the cylinder can be moved up and down, and a push rod for pushing down the upper discharge valve is hung down from the top wall of the cap screwed to the main cylinder, and the container body is squeezed from the above-mentioned cap removed state, the lower discharge is performed. The liquid that has entered the upper discharge valve lower chamber through the valve closes the upper discharge valve and pushes up the main cylinder. When the cap is screwed into the main cylinder from this state, the push-down rod opens the upper discharge valve. By pressing down while keeping it, the liquid between the lower discharge valve and the upper discharge valve is provided to be moved above the upper discharge valve, the cap is removed from this state, and the container body is squeezed. The liquid passing between the two discharge valves pushes the upper discharge valve upward, and the liquid is pushed up. In this way, the liquid inside the upper discharge valve is provided so as to be discharged from the upper end of the main cylinder. In this way, even a viscous liquid can be easily discharged without flowing outside air into the container body. It is provided to be able to.

たことを特徴とする定量液体注出容器。1. A tube container body 1 having a flexible trunk 2 and standing up a mouth and neck 3, a lower part of the main cylinder 12 to the outside of the mouth and neck, and a tube to the inside of the mouth and neck. An inner cylinder 14 hanging down via a first inward flange 13 attached to the lower part of the cylinder is non-rotatably fitted into the inner cylinder 14 to erect the main cylinder 12, and a second inward flange 15 is attached to the lower end of the inner cylinder. A main cylinder member that closes the upper end surface of the main cylinder with a top plate 17 of a central opening 16.
From the lower end of the fixed cylindrical portion 22 fitted to the inner surface of the inner cylinder 14, a plurality of spirally wound spring pieces 23 project at substantially equal intervals, and the tips of these spring pieces are attached to the outer peripheral surface of the valve plate 24. The first valve member 21 forming the lower discharge valve 25 in which the lower surface of the outer peripheral portion of the valve plate 24 is in contact with the upper surface of the inner peripheral portion of the second inward flange 15, and the inner peripheral surface of the main cylinder 12 is forcibly applied. A third inward flange is formed from the inner surface of the short cylindrical portion 32 in which the outer peripheral surface is slidably and watertightly pressed.
A plurality of engaging plates 43 are formed by engaging the sliding cylinder 31 projecting the 33 and the upper surface of the third inward flange 33 from the upper end of the bottomed cylinder 42 loosely inserted into the third inward flange 33. A tapered cylinder 44 having a larger outer diameter than the flange hole of the third inward flange 33 and a smaller outer diameter than the inner diameter of the main cylinder 12 is projected from the lower end of the bottomed cylinder downward and outward, and the sliding is performed. Moving cylinder 31
A second valve member 41 that closes and opens an upper discharge valve 45 formed by the inner peripheral lower surface of the third inward flange 33 and the upper surface of the tapered cylinder, and a top wall 52 to the outer surface of the main cylinder 12. A threaded peripheral wall 53 hanging from the outer periphery is used. A push rod 54 that is loosely inserted into the opening 16 from the center of the top wall 52 and hangs down is provided through a bottom plate of the bottomed cylinder.
12. A quantitative liquid dispensing container comprising a second valve member 41 pushed down to a lower portion and a cap 51 for closing the opening 16 with a cylindrical stopper 55 hanging down from the lower surface of the top wall 52.
