  The valve B2 is formed of a soft material such as rubber or soft synthetic resin, and an engagement cylinder portion 25 whose inner periphery engages with the outer periphery of the reduced diameter cylinder portion 14 of the measuring cylinder 6 of the lower cap base B1, A ring-shaped lower wall 26 whose upper surface is in contact with the lower surface of the lower wall 15, and a valve portion 27 that is suspended from the inner edge of the lower wall 26 and that is in contact with and engages with the outer periphery of the valve cylinder portion 17. It has.

  The upper cap C includes an upper cap base C1 and a piston body C2 attached to the lower part of the upper cap base C1.

The upper cap base C1 includes a top wall 30, a working cylinder 31 suspended from the lower surface of the top wall 30, a sealed cylinder 32 whose outer periphery engages with the inner periphery of the extraction cylinder 7 of the lower cap base B1, and the top wall 30 is provided with an outer cylinder 33 which is suspended from the outer edge of 30 and whose inner periphery is screwed onto the screw 11 on the outer periphery of the extraction cylinder 7 of the lower cap B.

An inner cylinder 36 that engages with the outer peripheral edge of the bottom wall 35, and an engagement cylinder 37 that engages with the outer periphery of the lower end of the actuating cylinder 31 of the upper cap base C 1 and the engaging portion 34. A diameter of the joint cylinder 37 is increased from the upper end, and a sliding portion 38 that slides in contact with the inner periphery of the cylinder portion 13 of the measuring cylinder 6 of the lower cap base B1 is provided.

Next, the effect of the container of this embodiment is demonstrated.
When the content liquid in the container main body A is weighed and used, first, the outer cylinder 33 of the upper cap C is gripped and rotated, the screwing with the lower cap B is removed, and the upper cap C is pulled up. .

When the upper cap C rises, as shown in FIG. 3, the sliding portion 38 of the piston body C2 slides in the cylinder portion 13 of the measuring cylinder 6 of the lower cap B, and in the measuring chamber a on the lower surface of the piston body C2. To negative pressure.
When the inside of the measuring chamber a becomes negative pressure, the ball valve 16 is pulled upward, the discharge port 21 of the valve seat 22 of the valve cylinder part 17 of the measuring cylinder 6 opens, and the discharge port 21 passes through the suction pipe 18. Then, the liquid in the container body A is sucked into the measuring chamber a.

  When the upper cap C is further raised and the sliding portion 38 of the piston body C2 is positioned on the diameter-enlarged cylindrical portion 12 of the measuring cylinder 6 of the lower cap B, the contact between the sliding portion 38 and the measuring cylinder 6 is released. As shown in FIG. 4, the upper cap C is removed from the lower cap B, the negative pressure in the measuring chamber a is eliminated, and the suction of the content liquid is completed.

  Simultaneously with the completion of the suction of the content liquid, the ball valve 16 is pulled downward by the negative pressure due to the suction of the content liquid in the container main body A, and engages with the valve seat 22 of the valve barrel portion 17 to cause the discharge port 21 to close. It is closed to prevent the liquid content in the measuring chamber a from being returned to the container body A.

  When the upper cap C is removed and the container is tilted, the content liquid weighed in the measuring chamber a can be poured out from the dispensing cylinder 7 of the lower cap B and used.

When the use of the content liquid is finished, the upper cap C is engaged with the lower cap B and pushed back as shown in FIG.
When the upper cap C is pushed back, the sliding portion 38 of the piston body C2 slides again in the cylindrical portion 13 of the measuring cylinder 6 of the lower cap B, and pressure is applied to the air in the measuring chamber a on the lower surface of the piston body C2. I will continue.

  When pressure is applied to the air in the measuring chamber a, the ball valve 16 closes the discharge port 21, so that the air passes through the flow hole 20 provided in the lower wall 15 of the measuring cylinder 6 and the lower wall of the valve B2. 26, the upper surface is pressed, the valve B2 is deformed, and the engagement between the valve part 27 of the valve B2 and the valve cylinder part 17 of the measuring cylinder 6 is released.

When the pushing of the upper cap C is finished, the valve B2 is not pressed by air, the valve B2 returns to its original shape, and the valve part 27 of the valve B2 and the valve cylinder part 17 of the measuring cylinder 6 are engaged again, Close the gap.
Since air is introduced into the container main body A from the gap between the valve part 27 and the valve cylinder part 17, the negative pressure in the container main body A can be eliminated.

When all of the measured content liquid is not used, the remaining content liquid can be returned into the container main body A through the gap between the valve portion 27 and the valve cylinder portion 17 together with the air by pushing the upper cap C.
Even when the content liquid is not measured and used, the content liquid remaining together with the air can be returned into the container main body A by pushing the upper cap.

By repeatedly pulling and pushing the upper cap C, the content liquid can be weighed and poured out in the measuring chamber a.
Finally, the upper cap C and the lower cap B can be screwed together to seal the inside of the container.

  The measuring container of the present invention is configured to set the diameter of the measuring cylinder 6 of the lower cap B, the height of the cylinder portion 13 of the measuring cylinder 6, and the diameter of the piston body C2 of the upper cap C and the upper cap base C1. The capacity of the measuring chamber a can be determined by setting the diameter and height of the working rod 31.

  In the above embodiment, the ball valve 16 is placed in the valve cylinder portion 17 below the measuring cylinder 6 of the lower cap B so as to be movable up and down, thereby forming a backflow prevention valve. As long as the liquid contents are prevented from flowing back, the ball valve system may not be used separately, and the backflow prevention valve system is not limited to the above embodiment.

  In the above-described embodiment, the flow hole 20 is drilled in the ring-shaped lower wall 15 provided at the lower end of the measuring cylinder 6, but the flow hole 20 is drilled in the peripheral surface of the lower end portion of the cylindrical portion of the measuring cylinder 6, The valve B2 may be provided.

  In the present invention, by pulling up and removing the upper cap from the lower cap, the liquid in the container can be measured and used in a measuring chamber in the lower cap. It can be widely used as a measuring container for other liquid contents.

It is a partial section elevation view of an embodiment container of the present invention. It is decomposition | disassembly explanatory drawing of a lower cap and an upper cap. It is explanatory drawing of a container when an upper cap is pulled. It is explanatory drawing of a container when an upper cap is removed. It is explanatory drawing when an upper cap is pushed in.
