In addition, the present invention provides a metering stopper that allows the user to arbitrarily set the required amount of liquid to be dispensed from the squeeze bottle depending on the type of liquid and individual differences.

[Summary of the Invention] The gist of the present invention is to provide a spouting cylinder having a spouting part at the upper end in the center of the bottom plate of the bottomed cylindrical inner stopper body that is fitted into the mouth of a squeeze bottle. is provided to protrude in the vertical direction, and a metering adjustment piece for adjusting the required amount of liquid to be poured out from the spouting part is provided on the lower side of the spouting tube, and the height can be freely adjusted. This consists in that a suction pipe is connected below the cylindrical body, the lower end of which reaches the bottom of the squeeze bottle.

[Embodiments of the invention] Hereinafter, one embodiment of the present invention will be described based on the drawings.

As shown in the figure, a side plate 2 of a bottomed cylindrical inner stopper main body 1 that is fitted into a mouth B of a squeeze bottle A made of soft plastic is attached to the outer circumferential surface of the upper end, and an upper end of the mouth B of the squeeze bottle is A contacting flange piece 3 is provided in a protruding manner, and at the center of the bottom plate 4 of the inner stopper body 1, a spouting cylinder 6 having a spouting part 5 at its upper end is provided to protrude 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 amount of liquid C to be poured is provided so as to be height-adjustable by vertically reversing means or the like. And the pouring cylinder body 6
A suction pipe 10 whose lower end reaches the bottom of the squeeze bottle A is connected below the bottle.

As shown in FIGS. 1 to 3, the spouting portion 5 of the spouting cylinder 6 has a closing piece 11 at the upper end of the spouting cylinder 6.
and a pair of spout holes 12 are formed so as to face each other on the lower side of the closing piece 11 of the spout cylinder 6, or
Alternatively, as shown in FIGS. 4 to 6, several spouting pieces 13 are formed 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. You may do so.

Further, a flange piece 3 is provided protrudingly on the outer circumferential surface of the upper end of the circumferential side plate 2 of the inner stopper main body 1, and the collar piece 3 comes into contact with the upper end of the mouth B of the squeeze bottle A. Although shown in the figure, the fitting groove is provided in the lower end of the circumferential side plate 2 of the inner stopper main body 1 so as to protrude from the lower end of the circumferential side plate 2 of the inner stopper body 1 so as to fit tightly into the inner stopper body 1. The stopper body 1 may be externally fitted tightly onto 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 portion 5 of the spouting cylinder 6 without being limited thereto. Further, although shown in the drawings, 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 they are connected.

Incidentally, D is a lug which 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, the body of the squeeze bottle A is appropriately pressed with one hand, so that the liquid C in the squeeze bottle A is sucked up. The pipe 10, the spout cylinder 6, the spout hole 12 of the spout part 5, or the spout piece 13 are successively passed through each other, and the squeeze bottle is pressed when it passes the upper end of the metering adjustment piece 8 of the metering adjustment body 9. When the squeeze bottle A is stopped, the force that returns the squeeze bottle A to its original state causes the constant adjustment piece 8 of the quantitative adjustment body 9 and each spout hole 12 of the spout portion 5 to be adjusted.
Alternatively, the liquid C is sucked into the squeeze bottle A from the suction pipe 10 through the spout cylinder 6 and between the spout pieces 13, and a required amount of liquid C remains in the inner stopper body 1. Therefore, the liquid C in the squeeze bottle A can be reliably dispensed in the required amount by simply 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. Since the height of the metering adjustment piece 8 which adjusts the required amount of the liquid C poured out from the spouting part 5 is freely adjustable, when the upper end of the fixed size adjustment piece 8 is moved to the highest position, the first As shown in FIGS. 3 and 4, when setting the fixed stone adjustment piece 8 upward, and moving the upper end of the quantitative adjustment piece 8 to the lowest position, move the fixed stone adjustment piece 8 downward as shown in FIGS. 3 and 6. When inverting the quantitative adjustment piece 8 downward and moving the upper end of the quantitative adjustment piece 8 to the intermediate position between the highest and lowest positions, the quantitative adjustment piece 8
By cutting the support part 7 of the bottle A short and lowering the supporting position of the support part 7 of the metering adjustment piece 8 which is in the upward position, the height of the upper end of the metering adjustment piece 8 can be easily adjusted. The required amount of liquid C to be dispensed can be arbitrarily set depending on the type of liquid C and individual differences.

In addition, the lower end of the squeeze bottle A is placed below the pouring cylinder 6.
By connecting the suction pipe 10 that reaches the bottom of the squeeze bottle A, it is possible to dispense the required amount of liquid C from the squeeze bottle A, or to remove liquid C beyond the spouting part 5 of the spouting cylinder 6. When the liquid C is sucked into the squeeze bottle A, the liquid C can be sucked up and sucked in smoothly and reliably.

Furthermore, if a closing piece 11 is provided at the upper end of the spouting cylinder 6 as the spouting part 5, and a spouting hole 12 is bored at the lower side of the closing piece 11 of the spouting cylinder 6, the body of the squeeze bottle A can be When you press the
Since the liquid C from below in the spout cylinder 6 hits the closing piece 11 and is poured out to the side through the spout hole 12, even if the body of the squeeze bottle A is pushed too much, the liquid C will scatter upward. can be reliably prevented. In addition, if several spouting pieces 13 are provided as the spouting part 5 at the upper end of the spouting cylinder 6, and the cut lines 14 are inserted radially from the center so that they can be opened and closed, the body of the squeeze bottle A' When the part is pressed, the liquid C from below in the spouting cylinder 6 hits each spouting piece 13 and is pushed upwards slightly, and is poured out from between the spouting pieces 13. It is possible to prevent the liquid C from scattering upward.

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 set it arbitrarily according to individual differences.
