Description

  The present invention relates to a plug for a liquid container for a coffee maker that injects coffee extracted by a coffee maker from a liquid inlet and stores the coffee.

  In coffee makers that drip coffee by pouring hot water into the ground coffee beans, the extracted coffee is often drip into a decanter that is a glass container. In such a case, since a decanter without a heat retaining function is used, the decanter is placed on a heat retaining heater. However, when time passes in the heat-retaining state, there is a problem that the water evaporates and the coffee is boiled or the flavor is impaired. Therefore, coffee is drip into a liquid container having a heat retaining function instead of a decanter. (For example, see Patent Documents 1 to 3). The heat insulation container used for such an application is configured so that coffee can be poured into the container without removing the plug of the heat insulation container even when the coffee is drip from the coffee maker. That is, by pressing an operating member disposed on the top of the plug, the water stop valve is opened to introduce the drip coffee into the heat retaining container (see, for example, Patent Document 4).

FIG. 8 shows a specific structure of a conventional heat insulation container stopper. The plug body 50 includes a plug body 52 provided with a liquid flow path 51, a water stop valve body 53 for opening and closing the liquid flow path 51, and an operation member 54 for opening and closing the water stop valve body 53. . When the end of the operation member 54 is pressed, the water stop valve body 53 moves downward to open the valve. On the other hand, when the pressing force at the end of the operation member 54 is removed, the water stop valve body 53 is moved upward by the urging force of the spring 55 built in the stopper main body 52 so as to be closed. Therefore, when drip coffee from the coffee maker, if the water stop valve 53 is opened by pressing the end of the operation member 54, the drip coffee passes through the liquid channel 51 from the liquid inlet 56. It will pass through and fall into the heat insulation container. A vent hole 57 is provided in the stopper main body 52 so that coffee can be smoothly poured from the heat retaining container into the coffee cup.

  However, in the above-described conventional plug body, most of the coffee dripped from the coffee maker is accommodated in the heat insulating container through the liquid injection port of the plug body, but the gap between the opening edge of the heat insulating container and the plug body. In addition, coffee flowed in, and a part of this coffee flowed into the internal space of the plug body and accumulated. Here, the plug body is provided with a vent hole for releasing water vapor from the coffee accumulated in the heat insulation container when the water stop valve is opened, but the vent hole is used for the coffee accumulated in the plug body. Since it is provided at a position higher than the liquid level, there is a problem that the coffee accumulated in the stopper overflows from the stopper. Further, even when a vent hole is provided in the horizontal plane at the bottom of the inner surface of the plug, coffee that has entered the plug will block the vent. As a result, water vapor in the heat insulation container is discharged from the liquid injection port through the liquid channel, and there is a problem that coffee overflows from the liquid injection port.

  Furthermore, if the liquid injection port is too small, the drip coffee closes the liquid injection port and overflows, and there is a problem that the coffee cannot be smoothly stored in the heat insulation container. On the other hand, when the pouring port is too large, the liquid flow is disturbed when pouring coffee into the coffee cup, and there is a problem that the surroundings are soiled. Therefore, there has been a strong demand for a configuration in which the liquid inlet has a sufficient opening area and the liquid flow is smooth.
