Next, the state of use and the effects of the metered discharge container of the present invention will be described.
The quantitative discharge container of the present invention is used as a container for quantitatively discharging ketchup, mayonnaise, mustard and the like containing a high-viscosity content and a granular mixture.

First, the lid member D is opened, and the contents are accommodated in the accommodating portion 3 of the container main body A and the cylinder tube 13 of the container base B.
At this stage, the valve member 26 is urged upward by the spring S and the discharge port 20 is closed, so that the contents are not discharged.

In discharging, as shown in FIG. 4, when the operating member C is pushed down, first, the valve member 26 slides in the valve seat 19 and the outer peripheral surface 29 of the piston member 25 of the operating member C is lowered.
Next, when reaching the upper end portion 13a of the cylinder cylinder 13 of the container base B, the valve portion 31 is separated from the valve seat 19, the discharge port 20 is opened, and the piston member 25 and the cylinder cylinder 13 are fitted, Starts functioning as a piston and cylinder and starts discharging.
When the piston member 25 reaches the lowest lowered position as shown in FIG.

In the present invention, since the discharge amount for one time is determined by the action of the piston and the cylinder whose stroke is always constant, the discharge amount for one time becomes substantially constant.
When the content is a low-viscosity fluid, it flows out due to its own weight simultaneously with the movement of the valve member 26, so the discharge amount for one time is not constant. However, in the present invention, the content is high-viscosity. Since it is difficult to discharge only by movement of the valve member 26, the discharge amount in one stroke can be made almost constant.

When the user releases the pressing of the operation member C, the piston member 25 is restored to the original position by the spring S.
At this position, the contents necessary for the next discharge flow into the cylinder cylinder 13 from the gap between the outer peripheral surface 29 of the piston member 25 and the upper end portion 13a of the cylinder cylinder 13 to prepare for the next discharge.

  Since the piston member 25 is restored to its original position and the valve member 26 blocks the discharge port 20, a predetermined amount of air is sucked into the inside due to the return stroke of the piston member 25. Even if is discharged, the inside of the container body A does not become negative pressure.

  When the operating member C is moved up and down, since the guide member 22 of the operating rod 23 is slidably guided by the inner peripheral surface of the upper cylindrical portion 2 of the container main body A, smooth movement can be achieved. .

In order to disassemble the quantitative discharge container of the present invention, it is only necessary to remove the container base B and the lid member D by unscrewing the container main body A and take out the operating member C and the spring S.
In addition, since the valve mechanism does not employ a delicate structure, reassembly and warming cleaning are easy.
When used for business purposes in a fast food restaurant or the like, the purpose of being able to perform quantitative discharge with a single operation can be achieved, and at the same time, the requirement for easy warming washing and refilling of contents can be satisfied.

  Since the upper cylindrical portion 2 of the container main body A is grasped and the pressing piece 38 can be discharged simply by pressing it down with the thumb, it is possible to answer a quick response at a fast food store or the like.

Next, a modified embodiment in which the structure of the operating member C and the lid member D is changed will be described.
In the present embodiment, the tip of the pressing operation portion of the actuating member C is rounded so that it can be pushed down directly with the thumb, and a through hole into which the pressing operation portion is inserted is drilled in the lid member. is there.

As shown in FIG. 6, the lid member Da is composed of a side peripheral wall 45 and a top wall 46, and a through hole 47 is drilled in the center of the top wall 46. It is inserted in the slidable up and down.
The upper end of the pressing operation portion 21a protrudes from the through hole 47 as much as necessary for the stroke.
About the structure of another part, it is the same as the said embodiment.

In this modified embodiment, the structure of the lid member Da can be simplified.
A large gap is generated between the push-down operation portion 21a and the through hole 47 of the lid member Da by the rib 27 of the push-down operation portion 21a. However, the gap acts as a flow hole for air to cope with fluctuations in pressure in the container. Can do.
With respect to other functions and effects, the same functions and effects as those of the above-described embodiment can be obtained.

The quantitative discharge container of the present invention can discharge a high-viscosity content quantitatively, and can be suitably used as a discharge container for seasonings such as ketchup and mustard, foods and the like.
Moreover, it can be widely used as a quantitative discharge container corresponding to other highly viscous contents such as cosmetics and liquid soap.
