Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a metering stopper used for dispensing a metered amount of liquid such as medicine, cosmetics, detergent, etc. in a squeeze bottle. It is something.

(Prior Art) Conventionally, as this type of metering stopper, for example, as disclosed in Japanese Utility Model Publication No. 36-14982, a metering storage tank, which is a metering stopper, is fitted and supported on the rim of the main body of a container made of synthetic resin. A dispensing cylinder having an upwardly dispensing hole is provided in the center of the bottom plate of this storage tank and protrudes in the vertical direction, and a metering pipe is formed at the lower end of the dispensing cylinder so as to fit a suction pipe into it. The structure of the collection bottle is disclosed. This presses the body of the main body of the container, causing the liquid inside the main body to flow through the opening at the lower end of the suction pipe,
A fixed amount of liquid is poured out from the spouting hole of the spouting cylinder into the storage tank. By fitting and forming a separate cylindrical body so that it can be adjusted up and down as appropriate, it was possible to adjust the amount of liquid poured out.

(Problem to be Solved by the Invention) However, the conventional quantitative adjustment in which the height is adjusted by adjusting the insertion and insertion positions of the separate cylinders of the dispensing tube always positions the cylinders at a constant position. It is extremely difficult to do so, and the insertion position is easily displaced due to wear and tear from long-term use or a small impact, resulting in an uncertain amount of liquid.

Therefore, the present invention was created to eliminate the above-mentioned drawbacks that existed in the past, and it is extremely easy to operate.
You can reliably pour out the required amount of liquid in the squeeze bottle, and you can reliably adjust the desired amount of liquid to be poured out from the squeeze bottle according to the type of liquid and individual differences. The purpose is to provide a metered volume stopper.

(Means for Solving the Problems) For this reason, the present invention provides a bottom plate in the center of a bottomed cylindrical inner stopper body that is fitted into the mouth of a squeeze bottle.
A spouting cylinder having a spouting part at the upper end is provided to protrude in the vertical direction, and a soft material is provided on the lower side of the spouting cylinder to adjust the required amount of liquid to be poured out from the spouting part. In addition to providing a quantitative adjustment piece shaped like a bowl that can be rotated in the normal direction, a suction pipe is connected to the bottom of the dispensing cylinder so that its lower end reaches the bottom of the squeeze bottle. Achieved the purpose.

(Function) Therefore, in the above invention, the bottomed cylindrical inner stopper body that is fitted into the mouth of the squeeze bottle has a spouting part at the upper end in the center of the bottom plate. A dispensing cylinder is provided to protrude in the vertical direction, and a reversible reversible member made of a soft material is provided on the lower side of the dispensing cylinder to adjust the required amount of liquid poured out from the dispensing part. A roughly teacup-shaped metering adjustment piece is provided, and by reversing the metering adjustment piece in the normal direction, the amount of water flowing from the suction pipe connected to the bottom of the dispensing cylinder reaches the bottom of the squeeze bottle. The amount of liquid that accumulates in the inner stopper body can be easily adjusted.

That is, by appropriately pressing the body of the squeeze bottle with one hand, the liquid in the squeeze bottle passes through the suction pipe, the spouting cylinder, and the spouting part in order and accumulates in the inner stopper body. At this time, if the metering adjustment piece is rotated in the normal direction into a roughly teacup shape, the liquid will accumulate up to the height of the upper end of the metering adjustment piece, and when you stop pressing the squeeze bottle at that position, the squeeze bottle will return to its original state. With the returning force, the liquid in the metering piece will flow into the spouting part,
The liquid is sucked into the squeeze bottle from the suction pipe through the dispensing cylinder, and the liquid remains in the inner stopper main body up to the height of the upper end of the metering adjustment piece which is rotated in the normal direction into a substantially teacup shape.

In addition, by inverting the approximately teacup-shaped metering adjustment piece,
Similarly, if the body of the squeeze bottle is pressed and the pressure on the squeeze bottle is stopped at the location of the spout, liquid will remain up to the height of the spout.

(Example) Hereinafter, one example of the present invention will be described based on the drawings.

As shown in the figure, the outer peripheral surface of the upper end of the circumferential side plate 2 of the bottomed cylindrical inner stopper body 1 that is fitted into the mouth B of the squeeze bottle A made of soft plastic, and the upper end of the mouth B of the squeeze bottle A. A contacting flange piece 3 is provided in a protruding manner, and a spouting cylinder 6 having a spouting portion 5 at its upper end is provided at the center of the bottom plate 4 of the inner stopper body 1 in a manner projecting upward and downward. Below the spouting part 5 of the spouting cylinder 6, there is a cylindrical support part 7 that is externally fitted and supported from the lower side of the spouting part 5 at approximately the center in the vertical direction, and A flexible rubber-made quantitative adjustment body 9 consisting of a substantially teacup-shaped quantitative adjustment piece 8 for adjusting the required quantitative amount of the liquid C to be poured is provided so as to be height adjustable by a positive reversal means in the vertical direction. A suction pipe 1 whose lower end reaches the bottom of the squeeze bottle A is disposed below the spouting cylinder 6.
It is a series of 0's.

Therefore, the spouting part 5 of the spouting cylinder 6 is as follows:
As shown in FIGS. 1 to 3, a closing piece 11 is provided at the upper end of the spouting cylinder 6, and a pair of spouting holes 12 are provided at the bottom of the closing piece 11 of the spouting cylinder 6, facing each other. Alternatively, as shown in FIGS. 4 to 6, several spout holes 13 are formed at the upper end of the spout cylinder 6, and a cut line 14 is formed from the center. It may be formed so as to be inserted radially and provided so as to be openable and closable.

In this way, as the spouting part 5, the closing piece 11 is provided at the upper end of the spouting cylinder 6, and the closing piece 1 of the spouting cylinder 6 is provided.
1, if the spouting hole 12 is bored on the lower side, when the body of the squeeze bottle A is pressed, the liquid C from below in the spouting cylinder 6 hits the closing piece 11 and flows out from the spouting hole 12. Since it is dispensed to the side, even if the body of the squeeze bottle A is pushed too much, the liquid C can be reliably prevented from scattering upward.

If several spouting pieces 13 are provided as the spouting part 5 at the upper end of the spouting cylinder 6, with cut lines 14 radially inserted from the center so that they can be opened and closed, the body of the squeeze bottle A is When the part is pressed, the liquid C from below in the spouting cylinder 6 hits each spouting piece 13 and is pushed upward slightly, and is poured out from between the spouting pieces 13. It is possible to prevent the liquid C from scattering upward.

Further, a flange piece 3 that comes into contact with the upper end of the mouth B of the squeeze bottle A is provided protrudingly on the outer peripheral surface of the upper end of the circumferential side plate 2 of the inner plug main body 1, so that the inner plug main body 1 is connected to the mouth B of the squeeze bottle A. Although shown in the figure, the inner plug main body 1 is not limited to this.
A fitting groove may be provided at the lower end of the peripheral side plate 2 so as to protrude so as to have a substantially downward U-shaped cross section, so that the inner stopper main body 1 is externally fitted tightly into the upper edge of the mouth B of the squeeze bottle A. In addition, the metering adjustment body 9 consisting of the support section 7 and the metering adjustment piece 8 is molded separately, and the support section 7 is extended from the lower side of the spouting section 5 of the spouting cylinder 6 to approximately the center in the vertical direction. Although shown in the figure as being fitted and supported, the metering adjustment piece 8 can also be integrally molded on the lower side of the spouting part 5 of the spouting cylinder 6 without being limited thereto. Furthermore, although the illustration shows that a separate suction pipe 10 is fitted to the lower end of the spout cylinder 6, the suction pipe 10 is not limited to this. It is also possible to integrally mold the spouting cylinder 6 and the suction pipe 10 so that it is possible to do so.

Incidentally, D is a cap that is fitted tightly onto the mouth B of the squeeze bottle A.

(Effects of the Invention) Since the present invention is configured as described above, when using the present invention, first press the body of the squeeze bottle A appropriately with one hand, so that the liquid C in the squeeze bottle A is sucked up. When the pressure on the squeeze bottle A is stopped after passing through the pipe 10, the spout cylinder 6, and the spout part 5 in order and beyond the upper end of the metering adjustment piece 8 of the metering adjustment body 9, the squeeze bottle A returns to its original state. Then, the liquid is sucked into the squeeze bottle A from the suction pipe 10 through the quantitative adjustment piece 8 of the quantitative adjustment body 9, the spouting part 5, and the spouting cylinder 6, and the required amount of liquid is drawn into the inner stopper body 1. C will remain. Therefore,
The liquid C in the squeeze bottle A can be reliably poured out in the required amount by an extremely easy operation of only pressing the body of the squeeze bottle A.

Moreover, a spouting cylinder 6 having a spouting part 5 at the upper end is provided at the center of the bottom plate 4 of the inner stopper main body 1 in a vertically protruding manner. , by providing a quantitative adjustment piece 8 in the shape of a bowl that can be freely reversible in the normal direction and made of a soft material to adjust the required amount of liquid C poured out from the pouring part 5, the quantitative adjustment piece 8 can be adjusted.
When moving the upper end of the
By turning the metering adjustment piece 8 upward as shown in the figure, the liquid C accumulates up to the height of the upper end of the metering adjustment piece 8. When you stop pressing the squeeze bottle A at that position, the squeeze bottle A returns to its original state. With the force that returns to , the liquid C in the quantitative adjustment piece 8 is
The liquid is sucked into the squeeze bottle A from the suction pipe 10 through the dispensing cylinder 6, and the liquid remains in the inner stopper main body 1 up to the height of the upper end of the metering adjustment piece 8, which is rotated in the normal direction into a roughly teacup shape. On the other hand, the quantitative adjustment piece 8
When moving the top end of
As shown in the figure, by inverting the quantitative adjustment piece 8 downward so that it faces downward, liquid remains in the inner stopper main body 1 up to the height of its spouting part. In this way, by reversing the metering adjustment piece 8 in the normal direction, the height of the upper end of the metering adjustment piece 8 can be easily adjusted. It can be set arbitrarily depending on individual differences.

Moreover, since the quantitative adjustment piece 8 is formed of a soft material and has a substantially bowl shape that can be freely reversed in the normal direction, this forward and reverse operation is extremely easy, and therefore the amount of liquid can be adjusted extremely easily. .

Further, since the amount of liquid is adjusted by reversing the approximately teacup-shaped metering adjustment piece 8 in the normal direction, the required amount of liquid can always be reliably obtained.

By cutting the support portion 7 of the metering adjustment piece 8 into a short length, the amount of liquid can be adjusted in advance to a desired amount.

In addition, by providing a suction pipe 10 below the spouting cylinder 6 so that its lower end reaches the bottom of the squeeze bottle A, it is possible to dispense the required amount of liquid C from the squeeze bottle A. When the liquid C that has exceeded the spouting part 5 of the spouting cylinder 6 is sucked into the squeeze bottle A, the liquid C can be drawn up and sucked in smoothly and reliably.

As explained above, according to the present invention, it is possible to reliably pour out the required amount of liquid in the squeeze bottle with an extremely easy operation, and the required amount of liquid can be poured out from the squeeze bottle depending on the type of liquid. Various effects can be obtained, such as being able to arbitrarily and reliably set the settings according to individual differences.
