It is preferable that the valve operating body is moved down so that the tea strainer is moved down together with the valve body so that the content liquid in the container body is discharged from the pouring port through the pouring passage.

[0018]

The operation of the present invention will be briefly described below, including the method of use. When a tea strainer is used, the tea leaves are put in the tea strainer, the tea strainer is attached to the stopper, and the stopper with the tea strainer is inserted into the upper opening of the container body. In this state, the lower end of the tea strainer has reached near the bottom of the inner container, and the tea leaves accommodated in the tea strainer are immersed in the hot water in the inner container. In the case where the stopper is of a pressing type, if the valve is opened by pressing the valve operating body, and the liquid container is tilted, the liquid in the liquid container can be discharged to the outside from the stopper injection passage. In the case of a commonly used screw-type plug, the liquid can be injected by loosening the plug and then tilting the liquid container in the same manner as described above.

When the plug is to be taken out of the upper opening of the container body when taking in and out the tea leaves and cleaning the tea strainer from the above-mentioned use condition of the tea strainer, the plug is moved to the upper portion of the container body while the tea strainer is connected to the plug body. It can be taken out from the opening.

When the plug with a tea strainer is taken out of the container main body, the present invention provides an air vent portion in an attachment portion between the plug and the tea strainer, or a coarse mesh on the upper side of the tea strainer. Since it is formed roughly, outside air is introduced into the tea strainer from the air vent portion or the coarse mesh portion. Therefore, the inside of the tea strainer does not become a negative pressure, the air escape is good, the drainage is good, and the tea strainer is easily removed from the plug.

Further, in the mesh of the tea strainer of the present invention, the lower side where tea leaves are heavily deposited is made dense (fine), and the amount of extraction from the lower side is smaller than that of the upper side. On the other hand, the upper side is made coarse (rough) within a range where tea leaves do not appear, the amount of extraction from the rough part is increased, and the amount of extraction from both the upper and lower parts is adjusted to obtain a uniform concentration as a whole. It is made to become.

Further, in the case of using a push-type plug having a liquid injection passage, a valve element, and a valve operating element, the plug and the tea strainer move up and down together with the valve operating element moving down or up. Since the tea strainer is moved and vibrated, the contact between the tea leaves in the tea strainer and the content liquid is promoted, and the tea brewing action is promoted.
