Description

[Detailed explanation of the idea] "Industrial application field" This proposal concerns a liquid container with a metering stopper.

"Prior Art" Conventionally, containers with measuring stoppers for powder are known.
In this container, the inside of the cylindrical measuring stopper fitted at the lower part of the mouth of the container body is divided into a measuring chamber and a measured powder storage chamber, and when the container body is turned upside down, the powder inside the container body flows into the measuring chamber. When the container body was returned to the upright position after filling, only the powder that had entered the measuring chamber moved by its own weight onto the guide plate into the storage chamber provided diagonally below the measuring chamber, and did not enter the measuring chamber. The powder is returned to the container, and when the container is turned upside down again, the powder in the storage chamber is discharged from the mouth above the storage chamber, and the powder enters the measuring chamber. By repeatedly turning the body upside down, a nearly constant amount of powder is discharged each time the body is turned upside down.

``Problem to be solved by the invention'' By slightly modifying the above-mentioned measuring stopper for powder, it should be possible to make it into a measuring stopper for liquids. However, measuring liquid with a measuring stopper obtained in this way is limited to cases where the container body is a normal container in terms of rigidity, and the container body is extremely thin-walled, which is currently being used. This cannot be done in the case of biaxially stretched bottles made of synthetic resin. That is, when the above-mentioned metering stopper is used in a normal container that does not easily deform, when the liquid water surface that enters the metering chamber by inverting the container body blocks the end surface of the outflow path from the container body to the metering chamber, Since outside air cannot flow into the container, the liquid cannot be replaced with air, and as soon as the measuring chamber is filled with liquid, the liquid stops flowing from the container into the measuring chamber. If the container is flexible and easily deformed, the negative pressure inside the container will be eliminated by squeezing the body by atmospheric pressure, and the liquid will continue to flow out, making the above measurement impossible. It was hot.

This idea makes it possible to measure even liquid contained in a flexible and easily deformable container body by providing a float that also serves as a valve body in the upper end of the outflow device to close the valve hole provided in the upper end. In addition, by making the above-mentioned valve somewhat breathable, it is possible to easily recirculate the outside air into the container body.

"Means for solving the problem" Container body 1 having a body that is flexible and easily deformed elastically
Then, the fitting tube 4 fitted into the container mouth neck 2 is vertically disposed from the periphery of the first bottom wall 5, and the measuring tube 6 is erected from the periphery of the first bottom wall, and A liquid outflow tube 8 lower than the measuring tube from the periphery of the opening 7 in the section
Stand up the valve plate 1 with a valve hole 9 on the inner surface of the upper part of the outflow tube.
0, a float 11 that also serves as a valve body and is fitted into the liquid outflow cylinder above the valve plate so as to be vertically movable and closes the valve hole 9 leaving a small gap; The inner surface of the measuring cylinder portion, which is approximately midway in the vertical direction between the plate and the first bottom wall 5, is closed with the second bottom wall 13, and a liquid outflow hole 14 is bored in the side portion of the second bottom wall near the liquid outflow tube. An outward flange-shaped top wall 17 is provided on the upper part of the nozzle 16 that stands up from the periphery of the opening 15 in the second bottom wall portion away from the liquid outflow hole, and a peripheral wall 18 that hangs down from the periphery of the top wall is connected to the upper end of the measuring tube. and an auxiliary cylindrical member 12 that is watertightly fitted into the auxiliary cylinder member 12, and is provided with a means for preventing the float from being pulled out from the liquid outflow cylinder.

"Operation" When the container body 1 is turned upside down from the state shown in FIG. When the container body is inverted, the air enters the inside (downward), and the replacement air flows through the nozzle 16, the liquid outflow hole 14, and the valve hole 9.
It enters the container body through. At the same time as the liquid water level that has entered the upper part of the measuring chamber closes the upper end surface of the liquid outflow tube 8, the replacement air stops flowing into the container, but from this state, the container body is squeezed with outside air. The liquid continues to flow out, and the float 11 reaches the valve hole 9.
By almost blocking the liquid, the liquid outflow is almost stopped and measured. When the container body is returned to the upright position from this state, the liquid contained in the upper part of the measuring cylinder will flow through the liquid outflow hole 14.
The first bottom wall 5 and the second bottom wall 1 at the lower part of the measuring cylinder 6
Enter the storage room between 3 and 3.

At this time, the liquid remaining in the upper end of the liquid outflow cylinder 8 enters the container body 1 through the small gap between the float 11 that also serves as a valve element and the valve hole 9, and enters the nozzle 16, the liquid outflow 14, and the float 11. Outside air flows into the container body through the small gap between the valve hole 9 and the valve hole 9, and the body returns to its original shape. Next, by inverting the container body, the liquid in the reservoir is discharged through the nozzle 16,
In addition, the liquid inside the container enters the measuring chamber at the top of the measuring cylinder and is measured.

If the amount of liquid to be measured is larger than the capacity of the storage chamber, it will not be able to fully enter the storage chamber when the container is upright, and will remain in the measurement chamber, and the remaining liquid will flow to the top of the measurement chamber the next time the container is turned upside down. It will be moved and weighed again.

"Example" 1 is a synthetic resin container body having a body that is flexible and easily elastically deformed by biaxial stretching, and 2 is its mouth and neck.

The fitting cylinder 4 of the main cylinder member 3 is inserted into the mouth and neck of the container body.
is fitted. The main cylinder member has a fitting cylinder 4 hanging from the periphery of the first bottom wall 5 and a measuring cylinder 6 erected from the periphery of the first bottom wall. Further, a liquid outflow tube 8 lower than the measuring cylinder stands up from the periphery of the opening 7 provided on the side of the first bottom wall, and a valve plate 10 with a valve hole 9 is provided on the upper inner surface of the outflow tube.

A float 11 which also serves as a valve body is fitted into the liquid outflow tube above the valve plate so as to be movable up and down. As described above, the float does not completely close the valve hole 9 when the container body is erect, but allows some liquid and outside air to pass through the valve hole.

Therefore, the lower surface of the float does not come into complete contact with the upper peripheral edge of the valve hole, but is provided so that some gap is formed.

The inner surface of the metering cylinder portion, which is approximately midway in the vertical direction between the valve plate 10 and the first bottom wall 5 mentioned above, is the second part of the auxiliary cylinder member 12.
It is closed with a bottom wall 13. As shown in FIG. 2, a liquid outflow hole 14 is bored in a side portion of the second bottom wall near the liquid outflow tube on the side of the second bottom wall. The nozzle 16 is made to stand up from the periphery of the opening 15 in the wall portion, and the peripheral wall 18 that hangs down from the periphery of the outward flange-shaped top wall 17 attached to the upper part of the nozzle is watertightly fitted into the upper end of the measuring cylinder to form the auxiliary cylinder member 12. is formed. A rod 19 as a means for preventing the float from being pulled out is suspended from the top wall 17, and this rod prevents the float from being pulled out of the liquid outlet tube 8 when the container is inverted.

A storage chamber is formed between the first bottom wall 5 and the second bottom wall 13 in the measuring cylinder 6, and the second bottom wall 13 and the top wall 1
Seven rooms form the measuring room.

"Effect of the invention" The present invention has the above-described structure, and a valve plate 10 with a valve hole is attached to the upper inner surface of the liquid outflow pipe 8 that stands up into the metering chamber from the first bottom wall that closes the upper end of the mouth and neck of the container body. A float 11 which also serves as a valve body is fitted into the cylindrical portion above the valve plate so as to be able to move up and down, and a means for preventing the float from being pulled out is provided, so that a predetermined amount of liquid enters the measuring chamber when the container body is inverted. When the valve hole reaches 1, the valve hole is reliably closed, so that the metering can be ensured even though the body of the container is elastically deformed. Also, the float 1 that also serves as the valve body
1 is provided so that the valve hole 9 is closed leaving a small gap, so that outside air enters the container through the small gap, and thus when liquid flows out, the outside air is elastically deformed and becomes negative pressure inside the container. It is possible to ensure the inflow of outside air.
