Also, a bottomed cylindrical valve case 38, which is also referred to as a valve box of the valve body 42, is provided immediately above the steam hole 27. A steam path 39 is provided on the lower surface of the valve case 38 in the vertical direction, and a valve seat 40 is provided in a planar annular shape at the upper end opening edge of the steam path 39. The valve seat 40 is formed of an elastic member 40A such as rubber, elastomer, or elastic synthetic resin in order to improve airtightness. A valve body 42 capable of opening and closing the valve seat 40 is provided above the valve seat 40. The valve body 42 is a metal weight body and is a sphere having a diameter larger than that of the steam path 39. The valve body 42 and the valve seat 40 in contact with the valve are integrated to form a unit. In this unit, the vapor passage 39 of the lid 9 and the inner plug vapor passage 35 are separated when the dispensing operation body 25 is not pushed at all times, and even if the pot is tilted in this state, the content liquid remains in the valve case. It becomes difficult to enter within 38. Further, a relay member 48 is provided between the pouring operation body 25 and the valve case 38 below it, and a member 24 for locking the elasticity of the spring 49 is provided on the outer periphery of the relay member 48. The spout operating body 25 and the unit are pushed upward by the spring 49 which is a body. Further, since the packing 53 is attached to the lid lower plate 9B and the relay member 48 and the packing 53 are in contact with each other, the content liquid does not enter the lid even if the pot is tilted. Accordingly, the inside of the lid is hardly soiled by the content liquid (FIG. 1).

On the other hand, when the pouring operation, that is, when the pouring operation body 25 is pushed, the unit moves downward, and the steam passage 39 of the lid 9 and the inner plug steam passage 35 communicate with each other via the packing 32, and at the same time, the electric air The switch operating member 31A of the switch 31 of the pump 8 is activated (FIG. 2). The unit is housed in the valve case 38 and can move up and down in conjunction with the dispensing operation body 25. When the dispensing operation is completed, the dispensing operation body 25 and the unit are pushed upward by the spring 49.

  Further, the relay member 48 is fitted on the outer periphery of the valve case 38 so that the valve case 38 can be pressed directly. A spring 49, which is a coil spring that expands and contracts in the vertical direction in the embodiment, is interposed under the pouring operation body 25. Therefore, when the dispensing operation body 25 is pressed, this pressing force can be transmitted to the valve case 38 via the relay member 48. The member 24 is provided with an interlocking portion 24A for pressing the switch operating member 31A.

  Next, the operation of the above configuration will be described. When the lid is opened, the knob 20B is tilted forward with the hinge shaft 20A as the center by pressing downward the action portion 20C opposite to the knob 20B of the lock operating portion 20 which is substantially flush with the lid upper surface 9A. When the knob 20B is picked up and pulled backward while being raised, the action part 20C moves the lock claw 21 forward against the spring 21A and engages with the locking claw locking piece 22 By releasing the stop state and further lifting the knob 20B upward, the lid body 9 can be erected so as to face upward via the hinge member 23.

  And after extracting the inner plug 12 from the shoulder member mouth part 6A, hot water is accommodated in the inner cylinder 2 through the shoulder member mouth part 6A using a kettle or the like.

  Next, the inner plug 12 is inserted into the shoulder member mouth 6A so as to insert the pumping pipe 10 into the inner cylinder 2, and the lid is closed. At this time, the lock claw 21 can be locked to the lock claw locking piece 22 according to the spring 21A. When the lid is closed, the lower end of the exhaust leakage preventing packing 32 is usually separated from the upper surface of the inner plug 12. Even if the lid falls, the liquid content does not enter the valve case 38, and the valve body Since the unit consisting of 42 and the valve seat 40 is in contact with the packing 53, even if it falls, the liquid does not enter the lid, and the inside of the lid does not get dirty (Fig. 1).

  Next, when the lock / unlock button 51 is operated to press the unlocking operation body 25 which has been unlocked, the unit consisting of the valve body 42 and the valve seat 40 is lowered, and the lower end of the exhaust leakage preventing packing 32 is Close contact with the top surface of the stopper 12 (FIG. 2). Further, the switch 31 is closed via the interlocking portion 24A by the pushing of the pouring operation body 25, and the electric air pump 8 is activated, and the compressed air is sealed from the exhaust hole 34 to the inner cylinder 2 from the exhaust hole 34. Then, the pressure is fed into the inner cylinder 2 through the air leakage prevention packing 33 and the inner plug air feed path 36 to increase the internal pressure of the inner cylinder 2. The water accommodated by the internal pressure of the inner cylinder 2 rising by this pumping is discharged through the pumping pipe 10 and the water injection pipe 11.

  At this time, if the pressure in the inner cylinder 2 is relatively high, there is a space above the valve body 42 made of a weight body, which causes the valve body 42 to finely move so that the pressure in the inner cylinder 2 is adjusted appropriately. Can be reduced to pressure.

As described above, according to this embodiment, even if the pot is provided with the steam path 39 in the lid, the content liquid does not enter the lid when the container is tilted. Further, by providing the inside plug steam path 35 of the inside plug 12 with a falling water flow prevention valve 37 that closes in the case of falling, it is possible to prevent flowing water at the time of falling.

Further, a lock claw 21 interlocking with the lock operation portion 20 provided on the upper surface plate 9A of the lid body 9 projects downward from a through-hole 9C formed in the lid lower plate 9B, and the lock claw 21 is disposed on the container body 5 side. The lock claw locking piece 22 provided in the lock claw 21 is provided so that it can be locked, and the lock claw 21 is provided with a cover portion 21B that slides integrally with the lock claw 21 to close the through portion 9C. Even if the claw locking piece 22 and the lock claw 21 are in the locked state or the non-locked state, the penetrating portion 9C is covered and closed by the cover portion 21B. When the lid 9 is forgotten and the lid 9 is closed, the vapor is less likely to enter the lid 9, and electrical components and metals inside the lid 9 are less likely to rust, thereby improving durability.
Further, in the present embodiment, a valve case 38 that is open on the valve seat 40 provided with a steam vent primary side hole 39 provided on the lid lower plate 9B side is provided on the valve seat 40. A valve body 42 that can be raised and lowered is provided so as to be openable and closable, and the valve body 42 is provided in a valve case 38 so as to be movable up and down.

  With such a configuration, in the electric air pot in which the inside of the inner cylinder 2 is pressurized by the pump 8 and the content liquid is poured out, the pump 8 is activated when the dispensing operation body 25 is operated, and pressure adjustment is performed. When the valve body 42 closes the valve seat 40, the pressure of the inner cylinder 2 is adjusted and then the content liquid can be poured out. Thus, when the dispensing operation body 25, which is a dispensing button, is pressed, the valve body 42 made of a metal ball is placed on the valve seat 40 to close it, and at this time, there is a space around the valve body 42. Yes, when the pressure in the inner cylinder 2 is high, it is finely moved to lower the pressure in the inner cylinder 2. When the dispensing operation body 25 is pressed, the switch 31 connected to the electric pump 8 is pressed almost simultaneously with the lowering of the unit, the pump 8 is activated, and the content liquid is pressurized. Therefore, when the dispensing operation body 25 is pressed, the content liquid can be dispensed while maintaining the dispensing flow rate within a certain range.

Further, an elastic member 40A is provided on the valve seat 40 which is closed by the valve body 42 made of a weight body. By doing so, in the elastic member 40A of the valve seat 40, when the valve seat 40 is made of resin, the pressure in the inner cylinder 2 is reduced even if the valve body 42 does not move finely due to micro unevenness on the resin surface. If the pressure is higher than the atmospheric pressure, the air escapes slightly, the pressure in the inner cylinder 2 decreases, and the amount dispensed decreases. By using the valve seat 40 as the elastic member 40A, the valve body 42 and the elastic member 40A are brought into close contact with each other, and the influence of micro unevenness is reduced, and the decrease in the amount of liquid dispensed when the temperature is low can be suppressed. In addition, since the pressure of the inner cylinder 2 is high when pouring hot water, the valve body 42 is finely moved to lower the pressure, so that even if the elastic member 40A is used, the amount of pouring does not increase excessively. Therefore, by using the elastic member 40A, the dispensing flow rate can be maintained within a certain range.

Also, releasing the spout body 25, the unit consisting of the valve body 42 and the valve seat 40 by the repulsive force of the elastic body such as a spring, is pushed up, away from the inside plug 12. And since the repulsive force (elasticity) of an elastic body such as a spring is only lifted and held, it is smaller than the force that pushes the manual bellows pump. It is much smaller than the air pot.

  Furthermore, by providing the pump 8, the switch 31, and its dispensing operation body 25 in the hollow portion inside the lid body 9, all electrical components are in the lid body 9. If the cover body 9 can be removed from the container body 5, the container body 5 can be washed without water entering the electrical parts by removing the lid body 9 when washing the container body 5. Become.

  Other embodiments will be described below. In addition, the same code | symbol is attached | subjected to the same part as the said Example 1, and the detailed description is abbreviate | omitted.

  FIG. 1 also shows a second embodiment, in which the packing 32 and the valve seat 40 in the first embodiment are integrated. By doing in this way, manufacturing cost can be reduced.

In Examples 1 and 2, lid packing 32 is provided on the cover 9, in this embodiment is provided on the inner plug 12 (FIG. 6). Even if it does in this way, the effect | action and effect similar to invention of Example 1, 2 are acquired.
