Abstract

PROBLEM TO BE SOLVED: To perform storing and injecting of liq. without using a liq. jetting pump and with a simple structure by providing an air suction valve which is constituted in such a way that it prevents air from exhausting from an air suction hole caused by compression of the body part of a container and open air is introduced through the air suction hole by elastic restoring of the body part after compression. SOLUTION: When a container is used and a lid body 6 is opened and the body part 8 of a container body 2 is compressed, a liq. filling bag 12 is pressed and a liq. opens a valve plate 17 and is injected from a jetting outlet 23. In addition, when compression of the body part 8 is released, the inside becomes to be negative pressure by elastic restoring force of the container body 2 and the liq. filling bag 12 is expanded and the liq. filling bag 12 is also made to be negative pressure to close the valve plate 17 and then, an annular valve plate 30 is opened and open air is introduced from an air suction hole 10. Then, when the storing liq. is injected out again from the condition where a part of the storing liq. is injected, even if air exists between the container body 2 and the liq. filling bag 12, air is not leaked outside from the air suction hole 10 caused by existence of the air suction valve and the liq. filling bag 12 can be surely pressed and the liq. can be surely infected.

And a circular pouring hole 16 in the center of the bottom wall 15.
Has been drilled.

The valve member 4 for the discharge valve is made of a flexible and highly elastic material such as an elastomer, and is used for discharging the stored liquid to the outside unilaterally. A valve plate 17 that is openably closed by closing the outlet hole 16
It has. In the present embodiment, a flange 19 extends inward from a lower end edge of a fitting cylinder 18 fitted to the inner surface of the inner plug peripheral wall 13 and a small-width bent portion 20 protruding from a part of the inner peripheral edge of the flange.
A valve plate 17 that closes the through hole 16 in a liquid-tight manner through the valve is provided.

The valve member for the discharge valve is not limited to the above embodiment. For example, a valve plate is provided at the center of the fitting cylinder 18 through a plurality of rod-like elastic plates protruding from the lower part of the inner surface of the fitting cylinder 18 in the circumferential direction. 17 may be supported.

The cap body 5 has a fitting cylindrical portion 21 fitted on the outer periphery of the mouth and neck portion above the intake hole 10 hangs down from the back surface of the top plate 22, and has an outlet 23 in the center of the top plate 22. Further, a peripheral wall 24 is suspended from the peripheral edge of the top plate 22 in a double cylindrical shape with the fitting cylinder 21, and the lower end thereof is suspended down to below the fitting cylinder 21. In addition, a seal cylinder 25 vertically provided from the center of the back surface of the top plate 22 is closely fitted to the upper portion of the inner surface of the fitting cylinder 18 of the valve member 4 for the discharge valve to achieve liquid tightness.

The valve member 7 for the intake valve includes the container body 8 described above.
To prevent the air from being exhausted from the intake hole 10 due to the compression of the air, and to form an intake valve configured to introduce outside air through the intake hole 10 by elastic restoration of the body 8 after the compression. , And a flexible and elastic material such as an elastomer. In the present embodiment, a tapered annular valve plate 30 is projected inward and obliquely upward from an annular base 29 fitted to the lower end inner surface of the cap main body peripheral wall 24, and this annular valve plate 30 is connected to the opening below the intake hole 10. The suction hole 10
Are closed. Further, the annular valve plate 30 is configured to be pressed against the outer peripheral corner of the step portion 11 facing upward to close the intake hole 10, and as shown in FIG. It is opened and introduced into the container through the intake hole 10, but as shown in FIG. 2 (b), even if the internal pressure in the container is high, the annular valve plate 30 does not open, and from the container through the intake hole 10. It is configured so that there is no leakage of air to the outside. The intake valve is not limited to the one in this embodiment, and may have another configuration as long as it has the above-described functions.

When the container constructed as described above is used, the liquid filling bag 12 is pressurized by opening the lid 6 and squeezing the body 8 of the container 2 from the state of FIG. The valve plate 17 is opened and poured out from the spout 23. When the squeezing of the body portion 8 is released, the container body 2 attempts to return to the original state by the elastic restoring force. Then, the valve plate 17 is closed, and then the annular valve plate 30 is opened by negative pressure inside the container body, which is still elastically restored, and outside air is introduced into the container body through the intake hole 10.

When the stored liquid is again discharged from the state where a part of the stored liquid has been discharged, even if there is air interposed between the container body 2 and the liquid filling bag 12, the air is present due to the presence of the intake valve. Is the intake hole 10
The configuration is such that the liquid filling bag can be reliably pressed without leaking to the outside, and the liquid can be reliably discharged. still,
Each of the above members is preferably formed of a synthetic resin unless otherwise specified.

[0020]

As described above, the liquid dispensing container of the present invention has a liquid filling bag 12 for sealing the stored liquid which shrinks as the stored liquid is taken out, and introduces outside air between the liquid filling bag 12 and the filled bag. And an air hole 10 for piercing the mouth and neck 9 and
