Description

[Detailed Description of the Invention] The present invention relates to a pump-filling type container in which the liquid in the liquid container can be poured out using pressurized air from an air pump, and particularly in such a container, the liquid in the liquid container can be poured out using pressurized air from an air pump. This relates to a natural pressure increase prevention structure.

In this type of pump liquid container, the inside of the liquid container is constantly connected to the outside air to prevent the pressure inside the liquid container from increasing naturally due to steam generated from the hot water stored in the liquid container when the pump is stopped. A steam release passage is required for communication, but in conventional pump liquid injection containers, the inside of the liquid container and the inside of the air pump are airtightly communicated, and the entire amount of steam generated in the liquid container is drained away. The steam enters the air pump through an air blowing passage inside the pump, and the vapor is discharged into the outside air from the pump suction port.

However, with this conventional pump-filled container, the entire amount of steam generated from the hot water in the liquid container enters the air pump, causing problems such as thermal deterioration of the air pump due to the large amount of steam. Ta. Additionally, if the container is accidentally tipped over, since the inside of the liquid container and the air pump are in airtight communication, a large amount of the liquid inside the liquid container will flow into the air pump, and the container will be When the pump is held upright, there is a risk that a large amount of liquid that flows into the pump will flow back into the liquid container together with a small amount of dirt attached to the inner surface of the pump. There is room for further improvement.

The present invention was developed in view of the above-mentioned problems.When the pump is stopped, the passage for blowing air into the liquid container is opened to the outside air between the liquid container and the air pump, and when the pump is pressed down, the passage for blowing air into the liquid container is opened to the outside air. By providing a valve body that acts to shut off the blow passage from outside air, and when the pump is not in operation, the inside of the liquid container and the outside air are always in direct communication without going through the inside of the air pump, thereby reducing the steam generated inside the liquid container. It is an object of the present invention to provide a pump liquid injection type container that prevents part or all of the liquid from entering the air pump.

Hereinafter, the pump injection type container of the present invention will be explained based on the illustrated embodiment. In the pump injection type container of the first embodiment of the present invention shown in FIG. , 3 is the hinge, 4 is the container body 1

A flange-shaped discharge port cover 35 is formed to open and close the discharge port from below. This discharge port cover 35 contacts the opening edge of the pump discharge port 24 from below to block the pump discharge port 24 when the pump is inactive, and when the pump is pressed down, moves downward as the push rod 30 moves downward to discharge the pump. The outlet 24 is opened.

Next, a method of using the pump liquid injection type container of the first embodiment and its function will be explained.

First, when the pump is at rest (the state shown in FIG.
The air blowing passage 16 on the stopper 9 side is opened to the space S between the lower surface of the pump bottom plate 22 and the upper surface of the lower mouth member 6, and the steam generated from the hot water W in the liquid container 5 is released from the air. The air is discharged from the upper end opening 16a through the blowing passage 16 into the space S between the pump bottom plate 22 and the lower mouth member 6, and is further discharged from the container body 1 and the lid body 2.
It is released into the outside air through the gaps etc. In this first embodiment, when the pump is not in operation, the pump outlet 24 is closed by the outlet cover 35, so that the steam released into the space S through the air blowing passage 16 is transferred to the air pump 9. There will be no inflow into the country. In addition, when the pump is stopped, the communication port 15 in the liquid passage 14 in the stopper is closed by the water stop valve 17, and even if the container is accidentally knocked over, the liquid W in the liquid container 5 is
There is no possibility that the liquid will flow out through the series of liquid pouring passages 11.

Next, when dispensing liquid, when the pump push plate 20 is pressed as shown in FIG. 2, the push rod 30 is moved downward by the push rod pressing spring 29 as the air pump 10 contracts, and the While opening the discharge port 24, the gasket 34 of the valve body 31
is in airtight contact with the top surface 9a of the stopper, and pressurized air from the air pump 10 is blown into the liquid container 5 through the air blowing passage 16. On the other hand, when the push rod 30 is moved downward, the water stop valve 17 is pushed down by the lower end of the push rod 30 through the membrane gasket 19 against the water stop valve push-up spring 18 to open the communication port 15. . The pressurized air blown into the liquid container 5 causes the liquid W in the liquid container 5 to pass through a series of liquid pouring passages 11 consisting of a liquid pumping pipe 12, a liquid passage in the stopper 14, and a liquid pouring pipe 13 to the outside. It is poured out to.

When the pump push plate 20 is released, the air pump 10 is extended by the pump extension spring 28, the push rod 30 is moved upward, and the water stop valve 17 is pushed in the valve closing direction by the spring 18. It is forced to return to the state shown in FIG.

FIG. 3 shows a pump filling type container according to a second embodiment of the present invention. The sealing member 37 is made of a stretchable material such as a rubber plate, and an annular packing 34 provided on the outer periphery of the valve disc 32 is integrally formed at the lower end of the sealing member 37 . That is, the seal member 37 is attached with its upper end fitted into the pump discharge port 24 and its lower end fitted onto the outer periphery of the valve disc 32.

4 and 5 show a pump injection type container according to a third embodiment of the present invention. In the pump injection type container of this embodiment, the push rod 30 is connected to the pump bottom plate 2
The lower part of the push rod protrudes below the pump bottom plate 22 through the push rod insertion hole 40 provided in the push rod 30.
An annular sealing member 37 that can close the push rod insertion hole 40 from above is attached to the middle position.
When the pump is pressed down, the seal member 37 is inserted into the push rod insertion hole 4.
0 can be closed from above. That is, when the pump is pressed down, the spring 2 for pushing down the push rod
9 pushes down the push rod 30, and the seal (sealing member) 37 at the middle part closes the push rod insertion hole 40 from above, and at the same time, the valve body 3 at the lower end of the push rod 30 closes the push rod insertion hole 40 from above.
A gasket 34 attached to the plug 1 comes into contact with the top surface of the stopper 9. Further, the push rod 30 is formed hollow, and a pump discharge port 24 is formed in the middle part of the push rod 30.
The pressurized air flows from the pump outlet 24 of the push rod 30 to the hollow part 41 in the push rod and the air vent 33 of the valve body 31.
The liquid is blown into the liquid container 5 through the air blowing passage 16 inside the stopper.

In the pump liquid injection type container of the third embodiment, the entire amount of steam generated in the liquid container 5 rises through the in-stop air blowing passage 16 and is discharged upward from the upper end opening of the air blowing passage 16. However, since the upper end opening is open to the outside air, a part of the steam released from the upper end opening flows through the air vent 33,
Although it is conceivable that steam may enter the air pump 10 through the hollow portion 41 and the pump discharge port 24, most of the steam released from the upper end opening is between the air blowing passage 16 and the valve body 31. It comes to be discharged from the open part into the space S between the pump bottom plate 22 and the lower mouth member 6. Therefore, the amount of steam entering the air pump 10 is reduced compared to the conventional pump liquid injection type container in which the inside of the liquid container and the air pump are airtightly communicated, and the problem of thermal deterioration of the air pump 10 is reduced. Reduced. In addition, in the third embodiment, when the liquid in the liquid container 5 flows out from the upper end opening through the in-stop air blowing passage 16 when the container is overturned, most of the liquid (or A part of the liquid flows out into the space S from the opening between the air blowing passage 16 and the valve body 31, compared to the conventional liquid container in which the inside of the liquid container and the air pump are in airtight communication. The amount of liquid flowing into the air pump 10 is reduced. Also, if liquid enters the air pump 10 when the container falls over, and when the container is placed upright, the liquid (which may contain a small amount of dirt) that has entered the air pump 10 may Even if the liquid flows down from the pump outlet 24 through the hollow part 41 and the air vent 33, all or most of the liquid flows out into the space S from the opening between the air blowing passage 16 and the valve body 31, The amount of liquid that flows back into the liquid container 5 through the air blowing passage 16 is almost negligible, and even if it is, it is a very small amount, so that no problems arise in terms of hygiene.

In each of these embodiments, a normal pump-filling container is used, but in other embodiments, a kettle-type pump-filling container may be used.

Next, to explain the effect of the present invention, according to the pump liquid injection container of the present invention, when the pump is extended, the air blowing passage 16 formed in the relay member 9 blows outside air between the pump bottom plate 22 and the relay member 9. Since it is open to the liquid container 5, all or part of the steam generated in the liquid container 5 is released into the outside air from between the pump bottom plate 22 and the relay member 9, and the vapor generated in the liquid container The amount of steam that enters the air pump 10 can be reduced compared to a conventional pump liquid container in which the entire amount of steam passes through the air pump and is released into the outside air. This has the effect that the liquid container 10 is less susceptible to thermal deterioration or thermal deformation due to the steam generated within the liquid container 5.

Further, according to the pump liquid filling type container of the present invention, since the air blowing passage 16 is open to the outside air between the pump bottom plate 22 and the relay member 9, if the container is accidentally tipped over, the air All or part of the liquid in the liquid container 5 that has passed through the blowing passage 16 reaches the pump bottom plate 2.
The amount of liquid that flows into the space between 2 and the relay member 9 and enters the air pump 10 can be reduced, and even if the liquid enters the air pump 10, When the overturned container is uprighted, all or most of the liquid that enters the air pump 10 and flows out of the pump from the pump outlet 24 flows into the space between the pump bottom plate 22 and the relay member 9. Air pump 1
It is possible to prevent the liquid that has flowed into the pump from flowing back into the liquid container 5 through the air blowing passage 16 together with a small amount of dirt in the pump, or to minimize the amount of liquid flowing into the liquid container 5. It has the effect of being more hygienic to use than conventional methods.
