Description

[Detailed Description of the Invention] The present invention relates to a siphon-type air pot.

Conventional siphon-type air pots have a pumping action by force-feeding pressurized air from an air pump in a lid body that is pivotally attached to the top of the pot body so as to be openable and closable to a liquid container in the pot body, and a liquid supply to the liquid container. A liquid pumping pipe that hangs down to the inner bottom of the liquid container from an inner stopper that is tightly fitted into the mouth, a liquid passage inside the inner stopper, a communication pipe that extends in a substantially horizontal direction from the inner stopper, and a liquid container that is outside the pot body. The liquid in the liquid container can be continuously poured out to the outside by the siphon effect of a series of pouring passages consisting of pouring tubes that can hang down approximately at the same level as the inner bottom. However, in this case, the airtightness of the connection between the communication pipe and the spouting pipe is maintained by the pressing force of the lid against the inner stopper when the lid is closed, so airtightness may be poor due to insufficient pressing force. There was a problem in that there was a risk of liquid leakage and poor pouring.

In view of the above-mentioned problems, the present invention aims to improve airtightness between the communication tube and the spouting tube by configuring the top surface of the tip of the communication tube so that it can be pressed by the lid when the lid is closed. The purpose is to

DESCRIPTION OF THE PREFERRED EMBODIMENTS A siphon-type air pot according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a pot body, and 2 denotes a lid pivotably attached to the upper part of the pot body 1 so as to be openable and closable.

A liquid container 3 made of a vacuum double bottle is housed in the pot body 1, and a lower mouth member 4 is attached above the liquid container 3. The liquid supply port 5 of the liquid container 3 is tightly fitted with an inner stopper 6 having an air passage 7 and a liquid passage 8 therein.

The inner stopper 6 is connected to a liquid pumping pipe 9 that hangs down from its lower surface to the inner bottom of the liquid container 3, and a communication pipe 10 that extends from its side surface in a substantially horizontal direction to reach the beak 4a of the lower mouth member 4. They are communicatively connected via a liquid path 8. Moreover, the pot body 1 is attached to the lower mouth member beak 4a.
A spouting pipe 11 is provided outside and hanging down at the same level as the inner bottom of the liquid container 3. The distal end opening 10a of the communication tube 10 is directed downward, and the distal end opening 10a can be brought into contact with the upper end opening 11a of the spouting tube 11. In this embodiment, a gasket 12 is interposed between the two.

Thus, a series of pouring passages 13 is constituted by the liquid pumping tube 9, the inner stopper liquid passage 8, the communicating tube 10, and the pouring tube 11.

The spouting pipe 11 is inserted from above into the through hole 15 at the center of the funnel-shaped engagement recess 14 provided on the bottom surface of the lower mouth member beak 4a, and then the spouting pipe 11 is inserted into the engaging recess 14.
While locking the upper end opening 11a expanded into a flap shape, a screw 11b provided at the lower end is made to protrude downward from the pipe cover 16 attached to the side surface of the pot body 1, and a splash prevention spout 17 is attached to the screw 11b. are screwed together until their upper end surfaces abut against the lower surface of the pipe cover 16.

On the other hand, a bellows type air pump 18 is disposed inside the lid body 2.

The air pump 18 is manually pressed by a disc-shaped pressing plate 19. Thus, the discharge port 20 of the air pump 18 can communicate with the air passage 7 of the inner stopper 6 when the lid is closed.

The lid 2 can be kept locked to the pot body 1 by a lock lever 21 when the lid is closed.

Reference numeral 22 is a projection with which the lock lever 21 engages.

In the bottom plate 23 constituting the lower surface of the lid body 2,
When the lid is closed, the thick portion 10 on the top surface of the tip of the communicating tube 10
A protrusion 24 is integrally provided at a position corresponding to b to abut against the thick portion 10b.

Therefore, when the lid is closed, a pressing force is applied to the communicating tube tip opening 10a due to the contact between the protrusion 24 and the thick walled portion 10b, thereby airtightly connecting the communicating tube 10 and the spouting tube 11. can be forced.

Here, the gasket 12 has a cap-shaped portion 12a fixed to the communicating tube tip opening 10a and the cap-shaped portion 12.
It is composed of a fin-like part 12b integrally protruding from the upper end of the cap-like part 12a and a fin-like part 12b.
By sealing in two places, we are trying to maintain even more airtightness.

FIG. 3 shows a modification of this embodiment,
In this case, the protrusion 24 on the lower surface of the lid body 2 is connected to the elastic member 25.
It is possible to absorb dimensional errors during construction such as design errors.

In the drawing, reference numeral 26 indicates the suction valve 27 of the air pump 18, an auxiliary suction valve, 28 an overturning water stop valve, 29 a water stop air inlet formed in the overturning water stop valve 28, and 30 an air inlet 29. The air supply valve 31 is integrally provided vertically with the suction valve 26 to be opened and closed, and 31 is a spring that biases the lock lever 21 in the locking direction.

FIG. 4 shows another embodiment of the invention. In this case, the lid 2 is attached to the pot body 1, the lock lever 21 is placed at the tip of the lid 2, and the bottom plate 2 is
3, and can be engaged and disengaged by horizontal movement. That is, lock lever 2
1 engages and disengages from a protrusion 22 provided at the tip of the beak portion 4a. A protrusion 24 is integrally provided at the rear end of the lock lever 21 to press against the thick wall portion 10b of the communication tube 10 when the lid is closed.

Next, the operation of the illustrated siphon type air pot will be explained.

When the inner stopper 6 is tightly fitted into the liquid supply port 5 and the lid body 2 is closed, the communicating tube 10 and the spouting tube are separated by the pressing force acting on the contact portion of the communicating tube thick portion 10b with the protrusion 24. 11 are airtightly communicated with each other to complete a series of pouring passages 13, pressurized air is forced into the liquid container 3 from the air pump 18 by pressing the press plate 19.
At this time, the air supply port 29 is closed by the air supply valve 30, the overturning water stop valve 28 is opened, and the pouring passage 13 is opened. Therefore, the liquid W in the liquid container 3 is continuously poured out to the outside through the pouring passage 17 due to the siphon effect.

Next, the effects of the siphon-type air pot of the present invention will be described.

According to the present invention, in the siphon-type air pot, the distal end opening 10a of the communicating pipe 10 extending from the inner stopper 6 in a substantially horizontal direction is directed downward, and the distal end opening 10a is aligned with the upper end opening 11a of the spouting pipe 11. The communication pipe 10 can be brought into contact with the
The top surface of the tip can be pressed at a suitable location on the bottom surface of the lid 2 when the lid is closed, and the pressing force connects the communication pipe 10 and the spouting pipe 11 in an airtight manner, thereby forming a series of spouting passages. 13 was completed, so the communication pipe 1
This makes it possible to easily and reliably improve the airtightness of the connection between the pipe 11 and the spouting pipe 11, and has the practical effect of providing a siphon-type air pot with good spouting performance.
