[Industrial applications]

 The present invention relates to a liquid quantitative dispensing container.

[0002]

[Prior Art] [Problems to be solved by the device]

 As a liquid quantitative dispensing container, a container as shown in FIG. 5 has been conventionally proposed. This container is composed of a container body 20 and a fixed-volume dispensing plug 22 fitted and fixed to a mouth-neck portion 21 of the container body 20. The valve seat 26 is provided at the upper portion of the inside of the spout cylinder 25, and has an intake cylinder 24 and a bottomed spout cylinder 25 that penetrate the cap top wall 23 that is fitted and hang down the lower end into the container body 20. A ball valve 28 is installed so that it can move up and down between the pipe and the bottom wall 27 of the spouting cylinder, and a spout hole 29 is formed in the cylinder wall below the valve seat 26, and a small through hole 30 is formed in the bottom wall 27 of the spouting cylinder. It is configured by drilling. Then, the valve body 28 that falls by tilting the container body 20 is limited in its descending speed by the negative pressure of the liquid that enters the pouring cylinder 25 through the small through hole 30 and reaches the valve seat. The liquid in the container is discharged through the discharge hole 29 through the discharge cylinder opening above the valve seat 26 at a substantially constant time until the air is displaced into the container as the liquid is discharged. It is configured to be inhaled via the.

In the conventional container of this type, the direction in which the container body is tilted when the liquid is poured out is limited. That is, when the container body is tilted to the intake cylinder side, it is difficult to smoothly pour the liquid because the opening part of the intake cylinder is blocked by the liquid poured out from the pouring cylinder opening, and as a result, a substantially fixed amount of liquid is poured out. It was impossible to do this, and there was room for improvement in this respect.

An object of the present invention is to propose an excellent container that solves the above-mentioned drawbacks of the prior art.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the container of the present invention comprises a container body 2 in which a mouth / neck portion 5 is erected from the upper end of a body portion 4 and a fixed amount dispensing plug 3 fitted and fixed to the mouth / neck portion 5. The stopper 3 is provided with a large-diameter short tube portion 8 having an upper end and a lower end surface opened through the center of a top wall 7 extending from the upper end edge of a fitting cylinder portion 6 fitted to the outer periphery of the container body neck portion 5. The upper end portion is supported in a double-tube shape inside the tubular portion 8 and the flow passage 11 is formed on the outer periphery thereof, and the bottomed inner cylinder 10 having the lower end portion hanging down into the container body 2 is provided. A ball-shaped valve element 14 that moves up and down between a valve seat 12 and an inner cylinder bottom wall 13 formed in the upper part of the cylinder 10 is provided, and an intake hole 15 is formed in the cylinder wall below the valve seat 12 and the inner cylinder is formed. 10 A small through-hole 16 was formed at the lower end of the structure.

[0006]

[Action]

 When the container body 2 is tilted from the state shown in FIG. 1, the liquid in the container body 2 is discharged from the flow path 11, and outside air is introduced from the upper end opening of the inner cylinder 10 into the container body 2 through the intake hole 15. It is introduced and replaced with liquid.

On the other hand, the valve body 14 falls in the inner cylinder 10, but the falling speed is limited by the negative pressure of the liquid introduced from the small through hole 16 in the inner cylinder bottom wall 13, and the valve body 14 is closed. It is possible to make the time to reach approximately constant. When the valve body 14 reaches the valve seat 12, the intake air is shut off, so that the pouring of the liquid can be stopped, and as a result, a substantially fixed amount of the liquid can be poured.

At the time of liquid pouring, the opening of the inner cylinder 10 at the center is used as an intake hole, and the tip of the flow path 11 between the inner cylinder 10 and the short cylinder part 8 at the outer periphery is constituted as a liquid pouring outlet. Even if the container body 2 is tilted in any direction, a good amount of liquid can be dispensed.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 and FIG. 2 show an embodiment of the present invention, in which 1 indicates a liquid fixed amount dispensing container. The container 1 is composed of a container body 2 and a fixed amount dispensing plug 3.

The container body 2 comprises a body 4 and a mouth / neck 5 standing upright.

Further, the fixed amount dispensing plug 3 is fitted and fixed to the container body 2 by a fitting tubular portion 6 which is fitted to the outer periphery of the mouth / neck portion 5, and a top wall 7 extending from the upper end of the tubular portion 6 is provided. It has a large-diameter short tubular portion 8 which penetrates the central portion and has open upper and lower end surfaces. The upper end of the outer peripheral wall of the cylinder wall is fitted and fixed to the tip of a plurality of ribs 9 projecting from the inner surface of the short cylinder portion 8 at equal intervals in the circumferential direction, and the lower end is hung down inside the container body 2. The inner cylinder 10 is provided, and a flow path 11 that communicates the inside and the outside of the container body 2 is formed between the outer peripheral upper part of the inner wall of the inner cylinder 10 and the inner circumference of the short cylindrical portion 8.

The inner cylinder 10 has a bottomed cylindrical shape with an open upper end, and a diameter of about 2/3 of the lower portion is slightly expanded, and an inward flange-like valve seat 12 is provided around the inner peripheral upper end of the expanded diameter portion. A ball valve element 14 is housed between the valve seat 12 and the inner cylinder bottom wall 13 so as to be vertically movable. Further, a plurality of rectangular intake holes 15 are formed in the circumferential direction in the cylindrical wall immediately below the valve seat 12, and a small through hole 16 for liquid injection is formed in the center of the bottom wall 13.

The ball-shaped valve body 14 is made of metal, has an outer diameter that is substantially equal to or slightly smaller than the inner diameter of the expanded diameter portion of the inner cylinder 10, and when the container body 2 is tilted, The lowering speed is limited by the negative pressure of the liquid that enters from the inside through the small through hole 16.

In this embodiment, the inner cylinder 10 is composed of a cylindrical peripheral wall constituting member 10A and a cap-shaped bottom wall constituting member 10B, and the bottom wall constituting member 10B is fitted to the lower end of the peripheral wall constituting member 10A. It is configured to be fixed. Also, in the figure, 17 indicates packing.

3 and 4 show another embodiment of the present invention. In this embodiment, the bottom wall constituent member 10B is rotatably fitted to the peripheral wall constituent member 10A, and the small through hole 16 is formed on the peripheral wall. The first small through hole 16a provided at the lower end of the constituent member 10A and the second small through hole 16b provided at the same level as the first small through hole 16a in the peripheral wall portion of the bottom wall constituent member 10B, By rotating the bottom wall constituent member 10 B, the opening area of the small through hole 16 is made variable so that the falling speed of the ball-shaped valve element 14 is made variable, and as a result, the amount of pouring out is made variable. . For example, if the opening area of the small through-hole 16 is increased, the amount of liquid per unit time that enters through the through-hole 16 increases, so that the falling speed of the ball-shaped valve element 14 increases, and as a result, the pouring hole The amount of liquid to be poured out is reduced.

[Effect of the device]

 As described above, since the container of the present invention has the above-described configuration, it is possible to pour a substantially fixed amount of liquid by simply tilting the container body, and even if the container body is tilted in any direction, Since it is possible to dispense a fixed amount, it is convenient compared to conventional containers of this type.
