It consists of a valve body 6 that comes into contact with the lower end of the stopper body, a push rod 7 that is suspended above the center of the top surface of the valve body, and a lever 8 that slides the push rod up and down.

As shown in FIGS. 3 to 5, the stopper body 4 has an outer hanging wall 9 screwed onto the outer periphery of the container body, and an inner hanging wall 10 hanging from the upper end of the outer hanging wall to the inner periphery of the mouth of the container body.
are integrally molded.

A screw is carved on the inside of the outer hanging wall 9 to be screwed into a screw for a stopper carved on the outer periphery of the mouth of the outer wall of the container body.

An annular seal packing 11 is provided on the outer periphery of the lower part of the inner hanging wall 10, which abuts the upper end of the annular protrusion at the lower part of the inner periphery of the inner wall opening of the container body, making the inside of the inner hanging wall hollow.

The valve body 6 abuts against the lower end of the inner hanging wall from inside the container body via a seal packing 12 to close the lower end of a liquid outflow portion 18, which will be described later.

As shown in FIGS. 3 to 5, the push rod 7 has its upper end inserted into a guide cylindrical portion 15 of the upper plate 5, which will be described later, without a gap, its lower end fixed to the valve body 6, and its upper end inserted into the guide cylindrical portion 15 of the upper plate 5. more prominent.

Reference numeral 13 denotes a spring that constantly presses down the valve body 6.

As shown in FIGS. 3 to 5, the upper plate 5 has a cover 14 that covers the upper part of the stopper body 4 except for the left and right side walls of the upper plate.
and a guide cylinder part 1 hanging downward from the center of the covering part.
5, and a lever locking part 16 at the upper rear end of the guide cylinder part.
are integrally molded.

A liquid outflow portion 18 communicating with the inside of the container body is formed between the cover portion 14, the guide tube portion 15, and the inner hanging wall 10 of the stopper body 4.

The cover part 14 of the upper plate has left and right side walls cut out to form a spout 17 that communicates with the liquid outflow part 18 between the left and right side walls of the upper end of the stopper body.

The lever locking portion 16 is connected to the cover portion 1 as shown in FIG.
4, and consists of a front flat part and a rear flat part which is one step lower than the front, and this rear flat part engages an engaging body 21 of the lever 8, which will be described later. A stopper 19 is provided.

This locking body 19 consists of a rear pin 19a fixed between the left and right side walls of a flat portion at the rear of the lever locking portion 16.

The lever 8 has its front end pivotally supported on the upper end of the push rod 7 via a front pin 20, and the lower surface of the front end is connected to the lever locking portion 1.
It is in contact with the upper surface of the flat part in front of 6.

The lever 8 is provided with an engaging body 21 at its rear end.

As shown in FIG. 5, this engaging body 21 consists of an elongated hole 21a formed in the rear end side wall and long in the front-rear direction.

A rear pin 19a passes through this elongated hole.
The long hole 21a of this lever 8 is movable back and forth with almost no vertical movement due to the rear pin.

To explain the operation, when you put your finger on the rear end of the lever 8 and press it toward the front of the stopper body 4, and then release your finger, the valve body 6 that was in contact with the lower end of the inner hanging wall 10 of the stopper body 4 will be removed.
slides upward against the spring 13, and the valve body is stopped with a gap created between the lower end of the inner hanging wall and the valve body.

That is, the lever 8 pushes down the rear end of the lever obliquely downward along the corner of the boundary between the front flat part and the rear flat part of the lever locking part 16, and pushes the tip of the lever upward.

Therefore, the push rod 7 whose lever tip is supported by the front pin 20 is simultaneously pushed upward, and the valve body 6 is also pushed upward.

In this state, there is no gap between the rear pin 19a and the top and bottom of the elongated hole 21a, and the elongated hole of the lever positions the rear pin 19a of the lever locking part 16 at the rear end of the elongated hole 21a, and stops. The rear pin 19a at the rear end of the hole resists the spring 13 which tries to push down the push rod 7, and prevents the rear end of the lever from moving upward.
The rear end of the lever will not slide upward unless an external force is applied to the tip of the lever.

When a gap is created between the lower end of the inner hanging wall 10 of the stopper body 4 and the valve body 6, the inside of the inner bottle of the container body 2, the liquid outflow portion 18, and the spout 17 communicate with each other through this gap. 5), insert the container body 2 into the spout 1
If the container body 2 is tilted toward 7, the liquid inside the container body 2 can be poured out.

Next, to stop dispensing the liquid, the tip of the lever 8 can be pushed down with a finger.

That is, the lever 8 pushes up the rear end of the lever 8 diagonally upward along the corner of the boundary between the front flat part and the rear flat part of the lever locking part 16, and pushes the tip of the lever 8 downward. Lower it.

Therefore, the elongated hole 21a of the lever is inserted through the rear pin 19a of the lever locking portion 16, and the rear pin 19a is positioned at the front end of the elongated hole to return the lever 8, and the front pin 20 is inserted into the upper end of the push rod 7. The tip of the lever, which is pivoted by the lever, is pushed down, thereby pushing down the push rod 7 and simultaneously pushing down the valve element 6 at the lower end of the push rod 7. The inner hanging wall 10 of the stopper body 4 is pushed down by the force of the spring 13.
The lower end and the valve body 6 come into close contact, thereby blocking the spout 17 and the liquid outlet 18 from the inner wall of the container body 2 (FIGS. 3 and 4).

6 and 7 show a second embodiment of the present invention, in which a magnet serving as an engaging body 21 is attached to the lower rear end of a lever 8 which is pivotally supported on the upper end of a push rod 7 via a front pin 20. 21b, and an iron plate 19 serving as a locking body 19 on the lower side of the lower wall at the rear end of the lever locking portion 16 of the upper plate 5.
b is buried, and the vertical sliding of the valve body 6 is regulated by magnetic force.

That is, to put the liquid into the liquid dispensing state, press the rear end of the lever 8 with your finger toward the front side of the stopper body 4, and the lever 8 will move between the front flat part and the rear flat part of the lever locking part 16. The tip of the lever is pushed upward along the boundary corner, and the rear end of the lever is pushed diagonally downward, and the magnet 21b of the lever attracts the iron plate 19b of the lever locking portion and stops.

Therefore, the push rod 7 that pivotally supports the tip of the lever via the front pin 20 is pushed up, and the valve body 6 is also pushed up, creating a gap between the lower end of the inner hanging wall 10 of the stopper body 4 and the valve body 6. The liquid can be poured out (Fig. 7).

In addition, to stop dispensing the liquid, push down the tip of the lever 8, and the tip of the lever will move along the corner of the boundary between the front flat part and the rear flat part of the lever locking part 16. When pushed downward, the rear end of the lever is pushed upward diagonally and returned to its original position, at the same time tightly closing the gap between the lower end of the inner hanging wall 10 and the valve body together with the force of the spring 13 (FIG. 6).

8 to 10 show a third embodiment of the present invention, in which a metal plate 19c serving as a locking body 19 is attached to the rear end left and right side walls and the lower wall of the lever locking portion 16 of the upper plate 5.
