Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a liquid spouting stopper, and more particularly to a liquid spouting stopper having a valve in its spout.

[Conventional technology]

In general, a liquid spout is provided with a spout for pouring out the liquid and an intake port for introducing air into the container after pouring out the liquid. A check valve is provided to prevent backflow, and a check valve is also provided at the intake port to prevent the liquid in the container from being discharged from the intake port.

In this way, conventional liquid spout taps have at least 2
Two check valves are required. The reason for this is that the valves installed on liquid spout valves generally open only in the direction in which liquid, etc. passes (referred to as the forward direction), and have a valve seat in the direction in which the liquid, etc. flows backwards (referred to as the reverse direction). There is a common sense that if it comes into contact with the valve and closes, but also opens in the opposite direction, it does not function as a valve. A check valve shall be provided at each opening.

[Problem that the invention attempts to solve]

However, doing this creates a spout and an inlet, and even if part of the spout and inlet can be used, two check valves must be provided, making the structure complicated. There are problems in that it becomes difficult to manufacture and increases manufacturing cost.

The present invention was devised in view of these conventional problems, and breaks the common sense of conventional valves to include a valve that opens in both the forward and reverse directions and that also functions as a valve. A technical problem is to provide a liquid spout plug that can completely serve as a spout and an intake port, and as a result has a simple structure, is easy to manufacture, and is inexpensive.

[Means for solving problems]

In order to solve the above-mentioned technical problem, the present invention provides a liquid spouting stopper in which a spout 11 is provided in the plug body 3 that closes the mouth 2 of the container 1, and a valve 12 is provided on the spout 11, as follows. technical measures were taken.

That is, the valve 12 is formed of synthetic resin, rubber, or the like, and is supported within the spout 11 by a support 13 and includes a thin disc 16 having flexibility and spring properties. , this disk 16
A valve 12 is formed by a ring 17 provided around the periphery of the valve and a ring 17 which is in contact with the inner wall of the spout 11 to form a liquid spout plug.

[Effect]

Usually, due to the springiness of the disk 16, the disk 16 becomes a flat plate, and a ring 17 on the periphery of the disk 16 connects to the spout 11.
The spout 11 is closed by contacting the inner wall of the spout 11. Then, when the container 1 is crushed by hand, the liquid inside the container 1 is released into the valve 12.
When you push it open and the water is poured out from the spout 11, when you release your hand, the container 1 returns to its original state, the inside of the container 1 becomes negative pressure, the valve 12 opens in the opposite direction, and outside air is sucked in from the spout 11. be done. When the suction of outside air is finished, the valve 12 returns to its original state and closes the spout 11. When the valve 12 opens, the disc 16 tries to return from a bent state to a flat state due to its spring properties, and since the diameter of the ring 17 also decreases when the valve 12 opens, it tries to return to its original diameter. , the return forces of the disk 16 and the ring 17 combine to hold the valve 12 in the closed state.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

A stopper body 3 is attached to a mouth 2 of a flexible container 1. This stopper body 3 is provided with a cylinder 5 having a slightly smaller diameter than the screw cylinder 4 on the upper surface of the screw cylinder 4 which is screwed onto the mouth 2 of the container 1, and further has a cylinder 5 having a diameter smaller than this cylinder 5 on the upper surface of the cylinder 5. It is formed by arranging nozzles 6 in series. This nozzle 6 has a closed end and has an annular groove 7 for breaking on the outer periphery of the middle portion thereof.

Then, by breaking this annular groove 7 portion, a spout 11 that communicates with the inside and outside of the container 1 via the cylindrical body 5 and the nozzle 6 is formed.

In addition, a valve 1 is provided inside the cylindrical body 5 which is inside the spout 11.
2 is provided. This valve 12 is supported by a support body 13 fitted into the cylinder body 5, and this support body 13 has a communication hole 14 formed by a notch and has a conical column 15 at the center of the upper surface.
The valve 12 is supported at the tip of the valve.

The valve 12 is made of synthetic resin and includes a flexible and springy thin disc 16 whose center is supported by the conical column 15, and a ring 17 provided around the periphery of the disc 16. ing.

Furthermore, this ring 17 normally closes the spout 11 by contacting the inner wall of the cylindrical body 5, which is the inner wall of the spout 11.

Then, by pressing the container 1 and releasing the pressing, the valve 12 also moves in the forward direction of pouring out the liquid.
It also opens in the opposite direction to draw in outside air. The valve 12 closes the spout 11 using the spring force of the disk 16 and the force of the ring 17 to maintain the circular shape.
Since the space between the container 1 and the inner wall of the container 1 is kept airtight, even if the container 1 falls, the liquid will not spill out.

In this embodiment, the screw tube 4 is used for screwing, but it may also be formed as a stopper that fits into the mouth 2 of the container 1.

Also, the meaning of the ring 17 coming into contact with the inner wall of the spout 11 is that when an annular plate 18 is provided on the inner wall as shown in FIG. 4 and a valve 12 is provided in the hole formed by the annular plate 18. This also includes the case where the ring 17 is brought into contact with the edge of this hole.

[Effect of idea]

According to the present invention, the valve breaks the common sense of normal valves and opens in both the forward and reverse directions, allowing it to be used both as a valve for pouring out liquid and as a valve for sucking in outside air. As a result, the spout and the intake port can be combined into one valve, and as a result, the structure is extremely simple, easy to manufacture, and inexpensive.
