Description of the Related Art In addition to a pot that is tilted and poured, there are an air pot that uses air pressure and a lower pouring type pot that uses the self-weight of the content liquid. The air pot has an inner container having an opening at the upper end, and a pump for feeding air must be mounted above the inner container for pouring.

On the other hand, the lower pouring type pot is provided with an inner container having an opening at the upper end and an outlet at the lower end. With this structure, the pump that is indispensable for the air pot is not required, and the force necessary for pouring (the force that pushes down the pump)
Since the operation position can be reduced, the pouring operation at a high place such as a table is easy.

However, there is a problem that the inner container having the heat retaining ability, which is opened at both upper and lower sides, is difficult to manufacture and the cost is high.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention makes it possible to use an inner container having an opening on only one side, so that the cost can be suppressed and the handling is extremely easy. The challenge is to provide a pot.

[0006]

A means for solving the above-mentioned problems will be described with reference to an embodiment of FIG. 1. The structure is such that a cartridge 2 for loading a content liquid 8 and the cartridge 2 can be attached and detached. The cartridge 2 accommodates an inner container 5 having an opening 4 at its lower end, and the opening 4 is closed by a removable plug body 7. 7, a discharge port 15 is formed, and the discharge port 15 is provided with an opening / closing means 17 that is biased in the closing direction to close the discharge port 15. The mounting table 3 is provided at a position corresponding to the discharge port 15. A flow passage 29 having an open upper end is formed, and a push-up means 37 for pushing up the opening / closing means 17 against the urging force of the cartridge 2 when the cartridge 2 is placed to open the discharge port 15 is formed. Pour out content liquid 8 into 29 Forming a closing valve 32 for controlling, characterized in that it is a said passage 29 bottom pouring type pot 1 derived in dispensing position spout 45 of the lower end.

In order to allow the content liquid 8 to be smoothly poured out, a vent hole 16 is formed in the plug body 7, and the vent hole 16 is biased in the closing direction. A second opening / closing means 18 for closing the inner container 5 and a pipe 26 reaching the upper end portion of the inner container 5 are provided, and a ventilation passage 30 having an upper end opening is formed in the mounting table 3 at a position corresponding to the ventilation hole 16. At the same time, when the cartridge 2 is placed, a push-up means 39 is formed which pushes up the second opening / closing means 18 against the biasing force thereof to open the ventilation hole 16, and opens the tip 46 of the ventilation path 30 to the atmosphere. Good.

Further, in order to maintain the mounted state of the cartridge and prevent the cartridge from being placed in the wrong direction, a fixing means for connecting the cartridge and the mounting table is formed on the outer surface of the cartridge and the mounting table. You can do it.

Further, in order to surely prevent the leakage of the content liquid, the fixing means may be composed of fixing metal fittings which apply an attractive force to each other.

[0010]

That is, according to the structure of claim 1, in use, the content liquid is first loaded into the inner container. This loading is
The cartridge is turned upside down, the plug is removed, the cartridge is inserted from the opening, and after loading, the plug is attached to return the cartridge to the original position. Then, it is carried to the position where the mounting table is installed and properly mounted on the mounting table. By this placement, the opening / closing means of the cartridge is pushed up by the pushing up means, and the inner container, the discharge port and the flow passage are all in communication. After that, if the on-off valve is operated, the content liquid is poured out from the pouring port through the flow passage.

According to the structure of claim 2, when the cartridge is mounted on the mounting table, the content liquid can be poured out, and the air flows into the inner container through the ventilation passage, the ventilation hole and the pipe. It becomes possible to smoothly pour out the content liquid through the discharge port and the flow passage. The liquid content contained in the pre-placement pipe of the cartridge is discharged through the ventilation hole and the ventilation passage when the mounting is completed.

According to the third aspect of the invention, the mounting of the cartridge may be performed by using the fixing means as a mark.

According to the structure of claim 4, when fixed by the fixing means, the cartridge and the mounting table are attracted to each other and are brought into close contact with each other.

[0014]

As a result of the above, according to the lower pouring type pot of claim 1, the content liquid can be injected and poured out from one opening formed at the lower end of the inner container, so that the upper and lower sides can be opened. The lower pouring pot can be obtained without using an inner container having a part. For this reason, the force required for pouring can be reduced, and the pouring operation at a high place such as a table is easy, but the cost can be suppressed, which is a remarkable advantage.

Further, since the cartridge and the mounting table are integrated at the time of mounting, in other words, the cartridge and the mounting table are completely divided in one virtual separation line, and the discharge port of the cartridge. Since it is provided with an opening / closing means which is normally closed, it is possible to keep the cartridge alone even after loading a hot beverage such as hot water.

For this reason, for example, the mounting table can be installed at a fixed location, and only the cartridge can be brought from the fixed location after loading the content liquid. This makes the mounting table lighter and smaller, and is easier to handle than carrying the entire pot.

According to the lower pouring type pot of claim 2, when the content liquid is poured out, the necessary amount of air flows through the ventilation passage, the vent hole and the pipe, so that the pouring of the content liquid can be performed quietly and smoothly. I can do it.

According to the lower pouring type pot of claim 3, since the fixing means is formed between the cartridge and the mounting table,
It can hold the mounted state of the cartridge surely,
Since the fixing means is formed on the outer side surface, the orientation of the cartridge can be prevented from being mistaken when mounting.

A see-through window 10 for seeing through the indicator pipe 9 is attached to the outer peripheral position of the indicator pipe 9. This is to grasp the amount of the content liquid.

A carrying handle 11 is attached to the upper end surface of the casing 6 for the convenience of carrying the cartridge 2. The carrying handle 11 can stand upright and can be tilted so that it does not project from the upper surface of the casing 6 when tilted. This is because it is necessary to invert the cartridge 2 when loading the content liquid 8 into the inner container 5.

Further, as shown in the drawing, a fitting convex portion 12 having a tapered surface 12a is formed on the lower end of the casing 6 so as to allow easy and correct placement on the placing table 3. Good.

Incidentally, as shown in FIG. 4, it is preferable to attach a carrying handle 13 that can be erected and tilted to the lower end surface of the casing 6 so that it can be buried. This is because it can be carried with either of the cartridges 2 facing up, and the handling when the content liquid 8 is empty becomes easy. In FIG. 4, 14 is a positioning protrusion for keeping the carrying hand in a buried state. A similar positioning protrusion may be formed on the attachment portion of the above-mentioned carrying handle 11.

The pouring of the content liquid 8 filled in the inner container 5 is set so as to be possible when the cartridge 2 is mounted on the mounting table 3. Therefore, the above-mentioned plug 7 is It is configured like. That is, the plug body 7 is formed with a discharge port 15 and a ventilation hole 16 that penetrate vertically, and these are provided with opening / closing means 17 and 18 that are biased in the closing direction and close each.

And a stopper 25 that holds the upper end of the coil spring 24.
It is good to consist of

The coil spring 24 and the stopper 25 may be attached by using a pipe 26 standing upright in the vent hole 16 of the stopper 7. The pipe 26 is set to a length that reaches the upper end of the inner container 5 so that the content liquid 8 can be poured out smoothly. The pipe 26 is preferably thin so as to reduce the leakage amount of the inner solution 8 when the cartridge 2 is mounted on the mounting table 3. For this reason, the upper part of the coil spring 24 and the stopper 25 is formed thinner.

As described above, the cartridge 2 has rod-shaped portions 19b and 23b of the valve members 19 and 23 from the lower end thereof.
Since it is in a protruding state, it can be grounded if it is upside down, but it cannot be grounded otherwise. Therefore, a dedicated support base 27 as shown in FIG. 5 may be provided. The support base 27 has a fitting recess 27 that fits into the fitting projection 12 at the lower end of the cartridge 2.
A concave portion 27b having a depth a at the upper end and having a depth that allows the rod-shaped portions 19b and 23b of the valve members 19 and 23 to hang down in the central portion.
Are formed and configured.

The mounting table 3 has a communication pipe 28 communicating with the above-mentioned indicator pipe 9 when the cartridge 2 is mounted, a flow passage 29 communicating with the above-mentioned discharge port 15, and a ventilation passage 30 communicating with the above-mentioned ventilation hole 16.

That is, the predetermined length of the rod-shaped portion of each valve member 19, 23 is set according to the positions of the frame member 37 and the contact portion 39.

In addition to the above-mentioned structure, for example, the first opening / closing means 17 and the second opening / closing means 18 are constituted by a check valve (not shown) mounted on the inner surface of the plug body 7 to constitute a pushing-up means. It may be configured by a rod-shaped body (not shown) provided above the flow passage 29 and the ventilation passage 30. In this case, no special biasing means is needed.

Further, the casing 31 is filled with a heat insulating material (not shown) and a heater (not shown) is internally provided so that the content liquid 8 existing in the communication pipe 28 and the flow passage 29 is filled. Insulation or heating may be performed.

Further, each packing 35, 36, 3 described above
As shown in FIG. 1, 8 is preferably formed so as to protrude from the upper end surface of the casing 31 that constitutes the mounting table 3 in a normal state. This is for pushing up the valve members 19, 23 after the packings 35, 36, 38 and their corresponding parts come into contact with each other to form an airtight state. This makes it possible to eliminate any leakage from the connection.

The on-off valve 32 in the flow passage 29 may be formed as a push button type as shown in the figure. Excessive protruding parts are eliminated and morphological stability is increased. A valve body 41 is attached to the tip of the push button 40, and the valve body 41 is biased by a stopper 42 and a coil spring 43 in a direction in which the flow passage 29 is interrupted. 44,44 in the figure
Is a ceiling.

The spout 45 at the lower end of the flow passage 29 is led out to the pouring position of the spout space 33, and the opening 46 at the lower end of the ventilation passage 30 is exposed to the atmosphere at the rear position of the spout space 33. It is open.

The pouring space 33 has such a height that a cup A or the like can be placed on the pouring space 33, and a detachable drainboard 47 is attached to the lower side of the pouring space 33. ing. The content liquid 8 existing in the pipe 26 when the cartridge 2 is mounted on the mounting table 3 is discharged and collected on the tray 48 through the above-mentioned ventilation passage 30.

The cartridge 2 and the mounting table 3 thus configured may be fixed to each other by various fixing means such as fitting, press-contacting and locking the fitting projection 12 and the fitting recess 34.
As shown in FIG. 2, it is preferable to connect with a plurality of fixing metal fittings 49 that apply an attractive force to each other. By fixing with the fixing metal fitting 49 as described above, the orientation of the cartridge 2 can be set correctly, and the discharge port 15 and the flow passage 29 to be connected and the ventilation hole 16 and the ventilation passage 30 can be completely connected. The leakage of the content liquid 8 can be reliably prevented. In order to eliminate any mistake in the orientation of the cartridge 2, for example, as shown by a phantom line in FIG. 2, the fitting portion between the cartridge 2 and the mounting table 3 can be fitted only in a fixed orientation. It is preferable to form the convex portion 50 on one side.

Further, in the structure using the above-mentioned fixing metal fitting 49, since the orientation of the cartridge 2 when it is mounted on the mounting table 3 is determined, the discharge ports 1 at different positions are arranged.
The direction must be set to be constant even when the above-mentioned plug body 7 having the vent hole 5 and the vent hole 16 is attached to the opening portion 4 of the inner container 5. For example, as shown in FIG.
The necessity can be eliminated by integrally forming the second opening / closing means 18 and the second opening / closing means 18 and setting them in the center of the opening 4.

That is, a discharge port 51 is formed in the center of the plug 7 that detachably closes the opening 4 at the lower end of the inner container 5.
The discharge port 51 is provided with an opening / closing means 52 which is biased in the closing direction to close the discharge port 51. The opening / closing means 52 has an upper end reaching the upper end of the inner container 5 and a lower end protruding downward from the discharge port 51. The pipe 53 is held, and the pipe 53 holds a closing member 55 which is biased in the closing direction and closes the vent hole 54 at the lower end of the pipe 53. Forming a flow passage 56 that opens, and pushing up the opening / closing means 52 and the closing member 55 against the urging force thereof when the cartridge 2 is placed,
A push-up means 57 for opening the discharge port 51 and the vent hole 54 is formed, and the push-up means 57 is connected to the vent hole 54.
It is formed in a tubular shape that communicates with, and branches from the inside of the flow passage 56, and the tip is open to the atmosphere.

Specifically, for example, the opening / closing means 52 described above.
Is composed of a valve member 59 formed by attaching an inversely tapered packing 58 to the tip of the pipe 53, and a biasing means including a coil spring 60 and a holding frame 61 for biasing the valve member 59. A ball may be held in the pore 54 as a closing member 55.

Further, the pushing-up means 57 is formed in a tubular shape for forming the ventilation passage 62, and a packing 63 having a substantially cylindrical shape is attached to the upper end of the pushing-up means 57 so as to maintain an airtight state with the ventilation hole 54 at the lower end of the pipe 53. A rod-shaped body 64 for pushing up the closing means 55 is biased upward and held on the upper portion of the pushing-up means 57. The rod-shaped body 64 is biased by the coil spring 65 in order to provide a time difference between the pushing up of the valve member 59 and the pushing up of the closing means 55.
This is to allow the closing means 55 to be pushed up after the pushing-up means 57 and the ventilation hole 54 at the lower end of the pipe 53 communicate in an airtight state.

In this case, the stopper 7 can be attached to the inner container 5 in a detachable manner, for example, by screwing.

Further, for the same purpose as described above, for example, the discharge port 51 and the flow passage 56 shown in FIG. 6 are formed at the centers of the cartridge 2 and the mounting table 3, respectively, and the outer peripheral portion of the upper surface of the mounting table 3 is formed. By forming a circular groove (not shown) at a position corresponding to the lower end of the indicator pipe 9, the cartridge 2 and the mounting table 3 can be connected by screwing.

In the pot 1 constructed as described above, when used, the content liquid 8 is first loaded into the inner container 5. This loading is performed by turning the cartridge 2 upside down and removing the stopper 7 from the opening 4. After the loading, the stopper 7 is attached and the cartridge 2 is returned to the original posture. Then, it is carried to the position where the mounting table 3 is installed, the position of the fixing metal fitting 49 is aligned as a mark, and the mounting table 3 is correctly mounted. In the case where they are collectively carried by being carried on a wagon or the like without being carried by hand, the support base 27 as shown in FIG. 5 is effective.

By this placement, the first of the cartridge 2 is
Due to the presence of the frame member 37, the valve member 19 of the opening / closing means 17 is
Further, the valve member 23 of the second opening / closing means 18 is pushed up by the existence of the contact portion 39, and the inner container 5, the discharge port 15, the flow passage 2
9, the inner container 5, the pipe 6, the ventilation hole 16 and the ventilation passage 30 communicate with each other. When the inner container 5, the vent hole 16 and the vent passage 30 communicate with each other, the content liquid 8 contained in the pre-placement pipe 26 of the cartridge 2 passes through the vent hole 16 and the vent pipe 30 by its own weight and is placed on the tray 48. Is discharged to.
After that, when the push button 40 constituting the opening / closing valve 32 is operated, the content liquid 8 is discharged from the pouring port 45 through the flow passage 29. At the time of pouring out the content liquid 8, the air can flow into the inner container 5 through the ventilation passage 30, the vent hole 16 and the pipe 26, and the content liquid 8 can be poured out through the discharge port 15 and the flow passage 29. It can be done smoothly.

Therefore, since the content liquid 8 can be injected and poured out through the single opening 4 formed at the lower end of the inner container 5, it is possible to use the inner container having both upper and lower openings.
The lower pouring type pot 1 can be obtained. For this reason, the force required for pouring can be reduced, and the pouring operation at a high place such as a table is easy, but the cost can be suppressed, which is a remarkable advantage.

Further, since the cartridge 2 and the mounting table 3 are integrated at the time of mounting, in other words, the cartridge 2 and the mounting table 3 are completely divided in one virtual separation line, The first opening / closing means 17 and the second opening / closing means 17 which are normally closed in the discharge port 15 and the ventilation hole 16 of the cartridge 2
Since the opening / closing means 18 is provided, only the cartridge 2 can be left alone even after loading a hot beverage such as hot water.

For this reason, for example, the mounting table 3 can be installed at a fixed location, and only the cartridge 2 can be brought from the fixed location after loading the content liquid 8. This makes the mounting table 3 lighter and smaller, and is easier to handle than carrying the entire pot 1.

Further, at the time of pouring out the content liquid 8, the necessary amount of air flows in through the ventilation passage 30, the ventilation hole 16 and the pipe 26, so that the pouring out of the content liquid 8 can be performed quietly and smoothly.

Further, since the fixing metal fitting 49 is formed between the cartridge 2 and the mounting table 3, the mounting condition of the cartridge 2 can be surely maintained, and since the fixing metal fitting 49 is formed on the outer side surface, the mounting At this time, the direction of the cartridge 2 can be prevented from being mistaken. Moreover, since the fixing metal fitting 49 attracts both of them to be connected, the portion to be connected can be surely connected and the leakage of the content liquid 8 can be surely prevented.
