BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid dispensing container.

[0002]

[Prior art]

As a liquid dispensing container for liquid dispensing, a container as shown in FIG. 5 has been proposed. This container is composed of a container body 20 and a fixed-rate pouring plug 22 fitted and fixed to the mouth and neck 21 of the container body 20.
Has an intake cylinder 24 and a bottomed discharge cylinder 25 whose lower end is suspended in the container body 20 through a cap top wall 23 fitted on the outer periphery of the mouth and neck 21. A ball-shaped valve body 28 is provided so as to be able to move up and down between a valve seat 26 provided at the upper part and a discharge cylinder bottom wall 27, and a discharge hole 29 is formed in a cylinder wall below the valve seat 26, and a discharge cylinder bottom wall is provided. 27
And a small through-hole 30 is formed. And the container body
The valve body 28 that falls by tilting the valve 20 is limited in its descending speed by the negative pressure of the liquid that penetrates into the pouring cylinder 25 through the small through-hole 30, and reaches a valve seat for a substantially constant time. The liquid in the container is discharged from the discharge tube opening above the valve seat 26 through the discharge hole 29, while the replacement air is sucked into the container through the suction tube 24 as the liquid is discharged. It is configured as follows.

[0003] In this type of conventional container, the direction in which the container is tilted during liquid pouring is limited. In other words, when the container body is tilted toward the intake cylinder, the liquid injected from the injection cylinder opening closes the opening of the intake cylinder, making it difficult to smoothly discharge the liquid. As a result, a substantially constant amount of liquid is discharged. It was impossible to do this, and there was room for improvement in this regard.

An object of the present invention is to propose an excellent container which has solved the above-mentioned disadvantages of the prior art.

[0005]

In order to solve the above-mentioned problems, the container of the present invention has a container body 2 having a mouth and neck 5 erected from the upper end of a body 4 and a fixed-rate dispenser fitted and fixed to the mouth and neck 5. Stopper 3
The spout 3 is a large-diameter short hole whose upper and lower ends are opened through the center of a top wall 7 extending from an upper end edge of a fitting cylinder 6 fitted to the outer periphery of the container body neck portion 5. A cylindrical portion 8 is provided, and an upper end portion is supported in a double cylindrical shape in the cylindrical portion 8, and a flow path is formed around its outer periphery.
11 and a bottomed inner cylinder 10 having an upper end opening with a lower end hanging down into the container body 2, and vertically moving between a valve seat 12 and an inner cylinder bottom wall 13 formed in the upper part of the cylinder 10. In addition to the provision of the ball-shaped valve element 14, an intake hole 15 is formed in the cylinder wall below the valve seat 12, and a small through hole 16 is formed in the lower end of the inner cylinder 10.

[0006]

When the container body 2 is tilted from the state shown in FIG. 1, the liquid in the container body 2 is poured out from the flow path 11 and the external air is discharged from the upper end opening of the inner cylinder 10 through the suction hole 15. 2 and replaced with the liquid.

On the other hand, the valve element 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 of the inner cylinder bottom wall 13, and the valve element 14 is moved to the valve seat 12. Can be made substantially constant. When the valve element 14 reaches the position above the valve seat 12, the intake is shut off, so that the discharge of the liquid is stopped, and as a result, a substantially constant amount of liquid can be discharged.

When the liquid is poured, the opening of the central inner cylinder 10 is formed as an intake hole, and the tip of the flow path 11 between the inner cylinder 10 and the short cylindrical part 8 on the outer periphery thereof is formed as a liquid outlet. Even if the container body 2 is tilted in any direction, a good quantity of liquid can be dispensed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a liquid dispensing container. The container 1
It comprises a container body 2 and a fixed-rate pouring tap 3.

The container 2 has a mouth and neck 5 standing upright from a body 4.

The fixed-quantity pouring plug 3 is fitted and fixed to the container body 2 by a fitting tube 6 fitted to the outer periphery of the mouth and neck 5 and a top wall 7 extending from the upper end of the tube 6. It has a large-diameter short tube portion 8 that penetrates the center and has upper and lower end surfaces opened. or,
The upper end of the outer periphery of the cylindrical wall is fitted and fixed in a double cylindrical shape at the tips of a plurality of ribs 9 protruding at equal intervals in the circumferential direction from the inner surface of the short cylindrical portion 8, and the lower end is suspended in the container body 2. A tube 10 is provided, and a flow path 11 communicating between the inside and outside of the container body 2 is formed between the outer periphery of the inner cylinder 10 and the inner periphery of the short cylinder portion 8.

The inner cylinder 10 has a bottomed cylindrical shape with an open upper end. The diameter of the lower portion is slightly increased by about 2/3, and an inward flange-shaped valve seat 12 is provided around the upper end of the inner diameter of the enlarged diameter portion. This valve seat 12
The ball-shaped valve element 14 is accommodated so as to be able to move up and down between the inner cylinder bottom wall 13. In addition, a rectangular intake hole 15 is formed in the cylindrical wall just below the valve seat 12.
A plurality of holes in the circumferential direction, and a small through hole for liquid injection in the center of the bottom wall 13
16 are drilled.

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

In this embodiment, the inner cylinder 10 is composed of a cylindrical peripheral wall component 10A and a cap-shaped bottom wall component 10B, and the bottom wall component 10B is fitted and fixed to the lower end of the peripheral wall component 10A.
