TECHNICAL FIELD OF THE INVENTION
The present invention relates to a stopper for closing an upper end opening of a liquid container such as a thermos bottle.
[0002]
[Prior art]
The stopper is for closing the opening of the liquid container, that is, the portion into which the liquid is poured, and is configured to be screwed to the liquid container in most cases.
[0003]
However, in the case of screwing, that is, turning and attaching and detaching, it is necessary to rotate the stopper every time liquid is injected, and the injection operation is troublesome. Then, the structure as disclosed in Japanese Patent Application Laid-Open No. 9-299254 was devised. That is, an injection passage penetrating vertically is formed at the center of the plug. According to this configuration, the liquid can be injected only by opening the openable top lid pivotally attached to the upper end of the stopper without removing the stopper, so that the injection operation is convenient.
[0004]
By the way, in the said invention, there is no structure which closes the pouring path which pours a liquid positively. As long as it is used normally, a means for closing the spout is not always necessary, but if the liquid container falls over, the liquid may spill through the spout.
[0005]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION Accordingly, it is a main object of the present invention to prevent inconvenience such as accidental spillage of a liquid while the injection of the liquid is simple.
[0006]
[Means for Solving the Problems]
Means for that is a plug of the liquid container formed by vertically penetrating an injection path for injecting the liquid into the liquid container to be attached, and tilting the liquid container toward the lower end of the plug. A discharging member for discharging the liquid, a closing member for closing the discharging passage so as to be openable and closable, and a biasing means for biasing the closing member in a closing direction. The closing member is displaced against the urging force of the above (1), and is a stopper of a liquid container provided with an operation member for opening the above-mentioned pouring path.
[0007]
That is, injecting the liquid is performed with the stopper attached, using the injection path. When the liquid is injected in this manner, the liquid inside does not flow out of the pouring path even if the liquid container is tilted. That is, the closing member is positively closed by the urging force of the urging means, and the operation member is operated to displace the closing member to open the pouring path. The operation member can be constituted by appropriate means such as a push button and a lever.
[0008]
It is preferable that a funnel-shaped recess is formed in the upper part of the injection path so that the liquid can be easily injected without zero.
[0009]
In addition, when the upper end of the injection path is opened and closed by a lid that can be opened and closed by a simple operation other than screwing, the liquid may spill out of the injection path when the liquid container falls, entry of dust, temperature of the liquid. Change can be prevented.
[0010]
Specifically, an opening / closing lid portion pivotally attached to the upper end portion and a locking portion for holding the opening / closing lid portion in a closed state are provided, and the upper end portion of the injection path is closed on the lower surface of the opening / closing lid portion. It is good to form the closing projection which does.
[0011]
Further, the operation member may be configured by a push lever having a pivot portion at one end and a push portion at the other end. Leverage principle can be used and it can be operated with light force.
[0012]
In this case, the pressing section may be located above a handle formed on the liquid container. Since the press lever can be pushed down using the fingers and thumbs of the hand holding the handle, it is possible to dispense with only one hand.
[0013]
【The invention's effect】
As described above, according to the present invention, the stopper is provided with the closing member for closing the spouting path, and the urging means for urging the closing member in the closing direction is provided. Can be closed. For this reason, even if the liquid container falls down, it is possible to prevent the liquid from spilling out of the pouring path.
[0014]
If the operating member for opening the pouring path is constituted by a pressing lever, the operation can be easily performed with a small force. In particular, when the pressing portion of the pressing lever is positioned above the handle of the liquid container, the liquid can be poured out with one hand.
[0015]
In addition, since the injection path is formed, it is not necessary to remove the stopper every time the injection is performed, so that the work required for the injection of the liquid is simple.
[0016]
As described above, since the liquid can be easily poured and the liquid can be easily injected as described above, a very easy-to-use liquid container can be obtained. In addition, since the pouring path is positively closed, when the liquid container is a heat insulating container such as a thermos, the heat insulating performance may be improved.
