FIG. 1 is a partially cutaway front view of a liquid container 1 having a liquid dispensing mechanism 5 according to an embodiment of the present invention, FIG. 2 is a plan view of a float 8, and FIG. FIG.

A liquid container 1 shown in FIG. 1 contains a viscous liquid L such as a liquid detergent and has a container body 2 made of synthetic resin. The container main body 2 includes a top-end cylindrical liquid storage portion 3 and a cylindrical mouth jaw 4 communicating with the liquid storage portion 3 and protruding downward. The liquid storage portion 3 is gripped with one hand. It is formed in a size that can be
And it is elastically deformable.

A liquid dispensing mechanism 5 is provided on the jaw 4. The liquid dispensing mechanism 5 includes a cylindrical guide member 6 provided coaxially inside the mouth 4. Guide member 6
And a floating member 8 slidably accommodated in the guide member 6 in the axial direction.

The guide member 6 is made of a synthetic resin, and is formed so that the outer peripheral surface is in contact with the inner peripheral surface of the mouth jaw 4 over the entire circumference and the entire length, and an inward flange 9 formed at the upper end.
And an outward flange 10 formed at the lower end. The outer flange 10 is mounted such that the back surface of the outward flange 10 is in contact with the lower end surface of the mouth jaw 4.

The lid 7 is made of a synthetic resin, and has a double-bottomed lid-shaped lid body 11 and a hinge 1 at the lower end edge of the lid body 11.
3 and a bottomed cylindrical cap 12 rotatable in a vertical plane.

The lid body 11 is made of an elastically deformable inner cylinder 14.
A fitting groove 15 extending in the circumferential direction is formed on the inner peripheral surface over the entire periphery, and the fitting groove 15 is formed on the outer peripheral surface of the mouth jaw 4 over the entire periphery. The cover body 11 is fitted and fixed to the mouth-and-jaw part 4 by fitting the cover body 16 with the cover body 16.

The inner surface of the bottom wall 17 of the lid body 11 comes into contact with the surface of the outward flange 10 of the guide member 6 when the lid body 11 is mounted on the mouth jaw 4. A cylindrical spout 18 protruding downward is formed on the bottom wall 17 of the lid body 11, and the spout 18 has a diameter smaller than the lower end opening of the guide member 6 and has a smaller diameter. Is provided so as to face the lower end opening.

On the inner surface of the cap 12, there is formed a projection 19 which fits into the spout 18 and seals it.

The float 8 is made of a synthetic resin and is formed in a cylindrical shape. The diameter of the float 8 is substantially equal to the inner diameter of the guide member 6, and the upper surface has a dome shape. The specific gravity of the float 8 is smaller than the specific gravity of the liquid L. When the float 8 is at the upper end position (the position in FIG. 1), the float 8 seals the opening 20 (see FIG. 3) formed inside the inward flange 9 of the guide member 6 and contacts the bottom wall 17 of the lid body 11. About 3cc of liquid L in between
Is formed so as to define a chamber 21 in which the filling port 18 is filled, and closes the spout 18 when the chamber 21 is at the lower end position (the position in FIG. 3).

As shown in FIG. 2, on the outer periphery of the float 8
A plurality of notches 22 extending over the entire length in the axial direction are formed.
Are in communication with each other. The diameter of the notch 22 is such that the liquid L cannot pass when the float 8 is pressed down by the liquid pressure by pressing the liquid container 3 and the liquid L does not pass when the float 8 rises from the lower end position. Are set so that they can pass.

As described above, when the float 8 is pushed down, the liquid L
Does not pass through the notch portion 22 and the liquid L passes through the notch portion 22 when the float 8 floats, because the velocity of the float 8 at the time of pushing down is higher than that at the time of floating, and the liquid L has viscosity. It depends. By providing such a notch 22,
It is possible to shorten the time from when the dispensing is completed (FIG. 3) to when the next dispensing is possible (FIG. 1). It should be noted that a hole having a similar effect may be provided in the float 8 instead of the cutout portion 22.

Next, the liquid container 1 constructed as described above is used.
How to use is explained. In the state shown in FIG. 1, when the liquid container 3 is gripped with one hand, the cap 12 is rotated to expose the spout 18 and the liquid container 3 is pressed, the liquid L
Is pressed, the float 8 is pushed down by the hydraulic pressure, and the float 8
Until the liquid reaches the lower end position, about 3 cc of the liquid L filled in the chamber 21 is discharged from the spout 18. Float 8
When it reaches the lower end position, as shown in FIG.
Is sealed by the float 8.

When the pressing force on the liquid container 3 is released, the liquid container 3 elastically returns to the state before the deformation, and the float 8 starts to float from the lower end position, and the notch formed in the outer peripheral portion of the float 8 The liquid L above the float 8 flows below the float 8 through a gap formed between the float 22 and the guide member 6 and the like. When the float 8 reaches the upper end position, the opening 20 formed inside the inward flange 9 of the guide member 6 is closed by the float 8 and the chamber 21 is filled with a predetermined amount of the liquid L. Can be poured out.

The present invention is not limited to the above embodiment, but can be implemented in various modes.

For example, in the above-described embodiment, the liquid metering / dispensing mechanism of the present invention is applied to the mouth and jaw of a liquid container having one liquid container and one mouth and jaw provided therein. Although the description has been made of the case where the liquid container is provided, the present invention is applied to each mouth and jaw of a liquid container including a plurality of liquid storage portions and a plurality of mouth and jaws respectively provided in each liquid storage portion. The liquid dispensing mechanism according to the invention may be provided.

In addition, the present invention can be implemented in various modes without departing from the gist of the present invention.
