Problems to be Solved by the Invention However, this structure requires operating mechanisms for operating the flaps on both the liquid container body and the stopper, and furthermore, it is necessary to precisely align their positions so that they cooperate. In addition, in order to open and close the flap, it is necessary to constantly bias the flap in the opening direction using spring means, which makes the structure complicated and may become unhygienic due to rusting of the spring.

Furthermore, since the flap is attached to the main body of the liquid container, the inside of the spout cannot be cleaned, and dirt such as scale is likely to accumulate.

The present invention was developed in view of the above circumstances, and it is an object of the present invention to provide a simple and sanitary structure that has a flap that opens and closes in conjunction with a push button.

Means for Solving the Problems The present invention is a stopper that closes the upper opening of the liquid container body, and has a valve that opens and closes the opening communicating with the liquid container body, and the valve is operated to open and close at the upper part. A push button is provided, a liquid flow path leading from the opening to a spout formed at a position opposite to the spout of the liquid container body is formed inside the stopper, and a push button is provided at the front of the stopper at the top of the spout of the liquid container body. A flap is protrudingly provided to cover the valve, and the flap is pivotably supported within the stopper, and the flap is operated by a push member provided in conjunction with the push button, so that when the valve is in an open state, The flap is linked to open the spout.

The present invention will be explained below with reference to the drawings. FIG. 2 shows a magic bottle as a liquid container equipped with a stopper according to the present invention, in which 1 is a liquid container main body, and a vacuum double bottle 3 is housed in an exterior body 2. A spout 4 is protruded from the upper front part of the exterior body 2, and a handle 5 is formed at the rear side. The upper opening 6 of the liquid container body 1 is closed by a plug 7 of the present invention, and the plug 7 is rotatably supported on the upper part of the handle 5 by a rotation shaft 8' via a connecting member 8. has been done.

FIG. 1 shows a stopper 7 of the present invention. Reference numeral 9 denotes a stopper body, which has an opening 10 in its lower part that communicates with the inside of the liquid container body 1, and a liquid passage 12 that communicates from the opening 10 with a spout 11 formed at a position opposite to the spout 4. There is. Further, 13 is an air vent hole. The upper part of the stopper body 9 is connected to the stopper cover 1.
Covered by 4.

Reference numeral 15 denotes a valve, and a valve body 16 opens and closes the opening 10 of the plug body 9.
A valve rod 17 erected on the upper part of the valve rod 6 penetrates the tap body 9, and a push button 18 fitted to the upper end of the valve rod 17 projects into the center of the tap cover 14. The valve 15 is always urged upward by a spring 19 and is operated by pushing a push button 18.

By pressing down the push button 18 once, the valve 15 moves down, the valve body 16 opens the opening 10, and the liquid passage 12 is maintained in a state communicating with the inside of the liquid container body 1, and the push button 18 is pressed again. As a result, the valve 15 is moved upward, and the valve body 16 closes the opening 10 again. Many such push button structures have been proposed, including the above-mentioned Japanese Utility Model Publication No. 58-30023, and an appropriate one can be selected from these known structures and used.

Reference numeral 20 denotes a flap provided protruding from the front part of the stopper 7, and is adapted to cover the upper part of the spout 4 of the liquid container main body 1. A base 21 of the flap 20 is rotatably supported within the stopper cover 14 of the stopper 7, and an operating portion 22 protruding from the base 21 is attached to a spring receiver 23 fixed to the valve rod 17 of the valve 15. The flap 20 is operated by a push member 24 protruding from the flap 20 to rotate the flap 20.

A detour portion 25 is formed in the center of the flap 20, and the detour portion 25 fits into the peripheral edge of the stopper cover 14 when the flap 20 is rotated upward. This eliminates the need to form a notch in the stopper cover 14 that allows the flap 20 to swing, increasing the strength of the stopper cover 14, and preventing foreign matter from entering the stopper 7 through the notch. Moreover, the appearance of the stopper 7 is not deteriorated by the notch.

26 is an opening button, and the opening button 26
A hook 27 is attached to the hook 2.
7 is adapted to be locked to a locking portion formed on the upper part of the exterior body 2. Then, by operating the open button 26 to release the lock between the hook 27 and the locking portion, the stopper 7 is moved upward as shown by the chain line about the rotation axis 8' between the connecting member 8 and the handle 5. The liquid container body 1 can be rotated to open the lid of the liquid container to inject and drain the liquid contents and to clean the inside of the liquid container main body 1.

Operation The solid line in FIG. 1 shows a state in which the liquid container main body 1 is covered with the stopper 7 and the valve 15 and flap 20 are closed. That is, the valve 15 is moved upward by the elasticity of the spring 19, and the valve body 16 closes the opening 10 of the stopper 7. The flap 20 moves downward due to the weight of its tip and covers the top of the spout 4. In this state, the liquid in the liquid container main body 1 cannot flow into the liquid passage 12 of the stopper 7, which prevents the liquid from leaking or cooling down. No dust or foreign matter can enter.

Next, when the push button 18 is pressed down and moved downward as shown by the chain line, the valve body 1 is moved through the valve rod 17.
6 moves downward as shown by the chain line, and the valve body 16 and opening 1
0 is opened, and the liquid passage 12 and the inside of the liquid container main body 1 communicate with each other. On the other hand, the spring receiver 23 also moves downward together with the valve lever 17, and the push member 24 causes the flap 2 to open.
0 is pushed down, the flap 20 is rotated clockwise about the base 21 as shown by the chain line, and the upper part of the spout 4 is opened. When the liquid container is tilted forward by gripping the handle 5 in this state, the liquid contained in the vacuum double bottle 3 is drained through the opening 10.
The liquid passes through the liquid passage 12 and is poured out from the spout 4 through the spout 11.

By pressing the pushbutton 18 again, the valve 15
moves upward, the valve body 16 closes the opening 10, and
The pushing down of the operation part 22 of the flap 20 by the pushing member 24 is released, and the flap 20 is rotated counterclockwise by the weight of its tip, and the spout 4 is rotated.

In the above description, the flap 20 is configured to rotate by the weight of its tip, but there is a spring means between the operating section 22 and the push member 24 that biases the flap 20 in the closing direction. Attach the
It is also possible to operate the flap 20 by the elasticity of the spring means.

In addition, by operating the cap opening button 26 to release the engagement between the hook 27 and the liquid container main body 1 and rotating the entire cap 7 upward, the cap 7 can be opened from the liquid container main body 1.
It can be removed from the top of the vacuum double bottle 3 to inject the content liquid or to clean the inside of the vacuum double bottle 3. The attachment part between the stopper 7 and the liquid container body 1 may be supported by a shaft 8' as shown in the drawing, but it can also be attached rotatably and removably by an appropriate means. Plug 7 when filling, draining, or cleaning the contents.
never gets in the way.

Effects of the invention According to the invention, since the flap 20 covering the spout 4 is opened and closed in conjunction with the opening and closing of the valve 15 by operating the push button 18, the flap 20 closes when not in use and dusts the spout 4. It can prevent foreign matter such as insects from entering, and when in use, the flap 20 is activated in conjunction with the operation of the push button 18.
Since the can be opened, the contents can be easily poured out.

Further, in the present invention, since the flap 20 is attached to the stopper 7, the operating mechanism for opening and closing the flap 20 in conjunction with the operation of the valve 15 is extremely simple, and the operating mechanism is provided in the liquid container body 1. Therefore, it is not necessary to precisely align the operating mechanisms of the stopper 7 and the liquid container body 1.
Furthermore, since the flap 20 is attached to the stopper 7, when the stopper 7 is removed from the liquid container main body 1, the flap 20 is also removed from the upper part of the spout 4, which is the flow path for the content liquid. 4 can be kept clean at all times.

Furthermore, in the known example, the flap is attached to the liquid container body and is always biased in the opening direction, so that when the cap is opened, the flap opening/closing mechanism is biased in the opening direction. becomes. Therefore, if the valve opening/closing mechanism of the stopper is in the closed state when closing the stopper again, the flap opening/closing mechanism of the liquid container body and the stopper will collide, so that the flap will close smoothly when the lid is closed. requires special structural consideration. However, in the present invention, since both the flap and the flap opening/closing mechanism are provided on the stopper, the stopper can be opened and closed regardless of the open/closed state of the valve or flap.

In the present invention, the stopper 7 may be attached to the liquid container body 1 by screwing, but the stopper 7 may be rotatable relative to the liquid container main body 1 as shown in the drawing. This has the advantage that the position of the flap 20 and the spout 4 will not be misaligned due to tightening or tightening of the screws, and the operation of opening and closing the stopper 7 is easy.
