Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is typified by an air pot, for example, and more specifically, a liquid storage section is provided in the outer case, and a liquid storage section is provided in the outer case, and the extrusion action of the pump mechanism is used to A liquid lift pipe located in the liquid storage part and guiding the liquid accumulated in the liquid storage part to the outside of the upper opening of the liquid storage part, and a liquid pump pipe for pouring the liquid from the liquid lift pipe out of the outer case. This invention relates to a liquid container with a tea strainer provided with a liquid pipe.

[Conventional technology]

In recent years, there has been a trend to enjoy tea easily by inserting a tea leaf storage case for a tea strainer into the liquid storage part (medium bottle) of a handy pot so that tea can be brewed immediately from the handy pot. In the field of tea ceremony, there is also a growing trend for air pots with tea strainers. To do this, it is necessary to insert the tea leaf storage case for the tea strainer into the liquid storage section, but in this type of liquid container, the liquid pumping pipe is located inside the liquid storage section, so this pumping liquid case is unavoidable. The problem is the connection between the tube and the tea leaf storage case for the tea strainer.

Therefore, in the past, a cylindrical body for inserting a liquid lifting tube was provided in a case constituting a tea leaf storage case for a tea strainer, so that the liquid lifting pipe was positioned so as to pass through the internal space of the case. A housing is used, and the housing is configured to be attachable by locking the housing to a drain tube provided at the opening of the liquid storage portion (see, for example, Japanese Utility Model Application Publication No. 15321/1983).

[The problem that the idea attempts to solve]

However, with the tea leaf storage case of the conventional structure described above, the tea leaves cannot come into direct contact unless the hot water in the liquid container is nearly full, and when the amount of hot water decreases, contact with steam occurs. Since tea can only be brewed using dewdrops, unless the hot water is kept full for a long period of time, there will be extreme differences in the concentration of the tea, and the components of the tea leaves will not be extracted sufficiently and efficiently. The problem was that it was difficult to do so.

In order to eliminate such inconvenience, for example,
The tea leaf storage case for the tea strainer is made extremely large,
It is also conceivable to position the liquid intake port of the liquid pumping pipe in the internal space of the tea leaf storage case for the tea strainer, and to draw out the tea directly from the internal space of the tea leaf storage case, but in this case, the above-mentioned A screen, etc. must be installed at the liquid intake port to prevent tea leaves from entering, and if used with a liquid container that does not come with a tea strainer, it will be of excessive quality (with a screen) and will not be compatible, so it cannot be used as a component of the liquid container. They tended to lack versatility.

The purpose of the present invention is to provide a tea leaf storage case for a tea strainer and a liquid lifting pipe that can efficiently brew tea regardless of the amount of hot water in a liquid storage part.

[Means to solve the problem]

The technical means of the present invention taken to achieve the above object is to provide a liquid storage section in the outer case, and to transfer the liquid stored in the liquid storage section into the liquid storage section by the extrusion action of the pump mechanism. In the liquid container 2 with a tea strainer, the liquid container 2 is provided with a liquid lift pipe that is positioned and leads to the outside of the upper opening of the liquid storage part, and a liquid injection pipe that pours out the liquid from the liquid lift pipe to the outside of the outer case. With respect to the liquid storage part, the liquid lifting pipe is installed at a position eccentric to the center of the upper opening of the liquid storage part, and adjacent to the liquid lifting pipe,
A tea leaf storage case for the tea strainer was installed with a lower end height comparable to that of the liquid lift pipe.

The tea leaf storage case for tea strainer may be attached to the outer case by supporting its upper end opening to the upper end opening of the outer case.

A mechanism for compressing the stored tea leaves may be provided in the tea leaf storage case for the tea strainer.

The tea leaf storage case for the tea strainer may be removably attached to the liquid lifting tube.

The tea leaf storage case for a tea strainer may be attached to an inner stopper that can close the upper end opening of the liquid storage section.

[Effect]

(a) By arranging the liquid lift pipe and the tea leaf storage case for the tea strainer adjacent to each other, there is no interference between the two, and the liquid lift pipe is not located inside the tea leaf storage case for the tea strainer. Therefore, the liquid storage inlet of the liquid lift pipe is not located inside the tea leaf storage case for tea strainers, or penetrates the wall of the tea leaf storage case for tea strainers and protrudes into the liquid. As an intake port, it is only necessary to form an opening that is large enough to take in the liquid.Also, as a tea leaf storage case for a tea strainer, it is necessary to take precautions against the passage of the liquid pumping pipe (by forming a through hole, or allowing tea leaves to pass through the through hole). (forming a seal structure to prevent leakage).

(b) Since the tea leaf storage case for the tea strainer is installed adjacent to the liquid lifting pipe and has the same lower end height as the liquid lifting pipe, liquid at a low level in the liquid storage section is also protected. By positioning the lower end of the tea leaf storage case at the same level as the liquid lifting pipe that extends close to the bottom so that it can be pumped out, tea can be brewed efficiently regardless of the amount of hot water in the liquid storage area. I can do that.

(c) In addition, by setting the lower end of the tea leaf storage case to the same height as the liquid lift pipe, the liquid intake of the liquid lift pipe is located extremely close to the position where tea leaves are present, allowing hot water supply or tea leaf injection. Immediately after that, tea brewing begins immediately in the vicinity, and it is possible to pour out the tea. Therefore, there is less time loss due to having to wait for the entire solution in the liquid container to reach a predetermined concentration by leaving it for a long time, and in this respect, tea can be brewed quickly.

(d) Furthermore, by installing the liquid lift pipe in an eccentric position, the upper opening of the tea leaf storage case for the tea strainer into which tea leaves must be placed can be moved to one side, and it is adjacent to the liquid lift pipe. The amount of protrusion of the liquid lift pipe into the tea leaf intake opening of the tea leaf storage case for the tea strainer, which is arranged as a tea strainer, can be minimized, and the protrusion of the liquid lift pipe will not cause any obstruction when putting tea leaves into the tea leaf storage case for the tea strainer. It is difficult to become

[Effect of idea]

According to function (a), since the liquid intake port of the liquid lift pipe merely forms an opening, it can also be used as the liquid lift pipe of a liquid container with a pump mechanism that is not equipped with a tea leaf storage case for a tea strainer, and Since the through hole is not required as a tea leaf storage case for a tea strainer, it can also be used as a tea leaf storage case for a tea strainer for other liquid containers not equipped with a pump mechanism.

Due to effects (b) and (c), tea can be brewed efficiently regardless of the amount of hot water in the liquid storage section, and tea can be drawn from near the location where tea leaves are present, making tea brewing even easier. There will be less time loss.

In addition, due to the effect (d), the opening area required for substantially inserting tea leaves in the tea leaf storage case for the tea strainer can be widened, making it easy to insert tea leaves.

In the liquid container with a tea strainer according to the second aspect, since the tea leaf storage case for the tea strainer belongs to the outer case side, tea leaves and liquid can be input while the tea leaf storage case for the tea strainer is attached, and the liquid can be poured. By adding it, you can immediately make tea.

In the liquid container with a tea strainer according to claim 3, when the tea leaves are compressed, the density of the tea leaves increases, and the contact action between the liquid and the tea leaves starts from the periphery of the tea leaf group, so that all the tea leaves do not come into contact with the liquid at once. Therefore,
No more overflowing tea.

In the liquid container with a tea strainer according to claim 4, by providing the mounting structure on the liquid pumping pipe, which originally has a simple structure, the structure for mounting it on the exterior case side, which originally tends to have a complicated structure, can be further improved. I have nothing to add.

In the liquid container with a tea strainer according to the fifth aspect, since the tea leaf storage case for the tea strainer can be removed as one piece when the inner stopper is removed, operability can be improved.

To explain the structure of this operation part HP, as shown in FIG. 17 are provided.

One of the pair of operation parts HP shown on the right in the figure has a pressure adjustment part PC attached above. Since the structure and operation of the pair of operation parts HP are almost the same, they will be described below together with the pressure adjustment part PC.

The operation piece 17 is formed with a protrusion 17a that is engaged with the opening edge of the operation member 16 to prevent it from coming out, and a flange 17b that is positioned opposite to the lower surface of the operation member 16. The tip of one arm 18a of the bifurcated operating fork 18 is in contact with the operating piece 17 from below.

Further, the operating member 16 stands up at the opening,
Further, a bent portion 16b is formed at the rising end thereof to wrap around the opening edge of the chamber body 14A.

Furthermore, a connecting piece 19 is placed on the upper edge of the operating piece 17 . This connecting piece 19 has a pair of overhanging parts 19a, 19b, and one end of each of a pair of compression coil springs 20, 21 arranged concentrically is engaged with the pair of overhanging parts 19a, 19b. It has been stopped.

The other end of the outer compression coil spring (hereinafter referred to as a first spring) 20 is locked to the end of the inner surface of a cylindrical body 22 connected to the upper part of the airtight chamber 14 . In addition, the other end of the inner compression coil spring (hereinafter referred to as the second spring) 21 is
The second spring 2 is inserted into the hole 22a in the end surface of the cylindrical body 22.
The cap member 23 is flexible in the installation direction of the cap member 23 and is fitted onto the inner surface of the cap member 23 in a manner that prevents the cap member from coming off.

The other of the pair of operation parts HP shown on the left side in the figure is not equipped with the pressure adjustment part PC, does not have the connecting piece 19, and replaces the first spring 20 with the operation piece 17 and airtight chamber 14. Cylindrical body 2 connected to the top
A downward biasing compression coil spring (hereinafter referred to as a third spring) 24 having a length of 2A is provided.

The aforementioned operating fork 18 is shown in FIGS. 1 and 3.
As shown in the figure, the pair of arms 18a are each curved and connected to the front cover part 2A of the case 2 in which the liquid injection tube 4 is installed, and a hole is formed at the position corresponding to the liquid injection tube 4. has been done. Also, a pair of arms 18
a is pivotally supported by a pair of brackets 33 fixed to the case 2, so that the operating fork 18
is attached to case 2 so as to be rotatable around axis _X1 .

A pair of free end edges of the swing arm 25 are in contact with the upper surface of the portion 18b of the operating fork 18 that straddles the liquid injection pipe 4. A boss member 26 having an oval-shaped engagement hole 26a in cross section is connected to the base end of the swing arm 25.
6 is pivotally supported by the cover portion 2A of the case 2.

Furthermore, the engagement hole of the boss member 26 is provided with the case 2.
A shaft portion 27a of the operating lever 27 extending laterally from the cover portion 2A of the case 2 is engaged with the shaft portion 27a, and this shaft portion 27a is pivotally supported by the cover portion 2A of the case 2.

In each of Figures 1 to 3, the operating lever 2 is shown.
7 is shown not being operated. In this state, as shown in FIGS. 1 and 2, the pair of arms 18a of the operating fork 18 are both located at the lower limit of their swing range. And operation piece 1
Numeral 7 is a downward biasing force exerted by the first spring 20, so that the protrusion 17a abuts against the opening edge of the operating member 16 and presses it downward.

Therefore, at this time, the chamber body 14A of the airtight chamber 14
is not bent by the operating member 16. Also,
At this time, the second spring 21 is in a free state, and the cap member 23 is at the lower limit of its movement range and closes the airtight chamber 14.

When the operating lever 27 is operated to swing downward from this state, the operating fork 18 is rotated counterclockwise around the axis _X1 in FIG. The tips of the pair of arms 18a move upward.

As a result, the operation piece 17 moves upward against the biasing force of the first spring 20, and the flange 17b of the operation piece 17 moves upward.
the operating member 16 is pushed up. Therefore, the chamber body 14A of the airtight chamber 14 is bent, and the airtight chamber 14
is deformed and reduced.

On the other hand, as the operating piece 17 moves upward, the second spring 21 pushes up the cap member 23. Thereby, the airtight chamber 14 is opened. Therefore, as the airtight chamber 14 is deformed and reduced, the airtight chamber 14
The air inside is discharged to the outside from the opening 22a of the cylindrical body 22.

A communicating cylindrical member 28 made of an elastic body attached to the upper lid 3 is in contact with the end surface of the cylindrical body 22, with its lower edge being elastically deformed. A hat-shaped valve body 30, which is urged downward by a compression coil spring (hereinafter referred to as a fourth spring) 29, comes into contact with the upper edge of the communicating cylinder member 28 to seal the inside.

The air discharged to the outside from the airtight chamber 14 as described above is guided into the inside of the communication cylinder member 28 in an airtight state. As the cap member 23 is pushed up by the second spring 21, it comes into contact with the lower end surface of the valve body 30, and pushes up the valve body 30 against the biasing force of the fourth spring 29.

As a result, the inside of the communication cylinder member 28 is connected to the upper lid 3.
It communicates with an air passage 31 formed on the upper surface of the lower member 3B, and air from the airtight chamber 14 is guided to this air passage 31. The outlet of this air flow path 31 passes downward through the inside of the inner stopper 5 from the upper lid lower member 3B and communicates with the remaining space inside the inner bottle 1 from between the stopper body 5A and the inner lid member 5B.

Therefore, the air discharged from the airtight chamber 14 is guided into the inner bottle 1, increasing the pressure in the remaining space. As a result, the liquid level in the medium bottle 1 is pushed down, and the liquid in the medium bottle 1 is force-fed through the liquid lift pipe 7 and the liquid guiding pipe 8 to reach the liquid injection pipe 4, and the tip of the liquid injection pipe 4. It is poured out from the outside.

On the other hand, if the swinging operation of the operating lever 27 is stopped, the operating piece 17 is pushed down together with the linking piece 19 by the biasing force of the first spring 20, as shown in FIG. As a result, the cap member 23 is no longer pushed up by the second spring 21, so the urging force of the fourth spring 29 is applied to the valve body 3.
0 is pushed down, and the communication cylinder member 28 and the air flow path 3
1 is cut off. Also, the second spring 2
1 returns to the free state, and the hole 22a of the cylindrical body 22 is closed by the cap member 23.

When the operating piece 17 is pushed down, the operating member 16 is locked to the protrusion 17a.
move downward, and along with this, the chamber body 14A of the airtight chamber 14, which is caught and locked by the bent portion 16b of the operating member 16, no longer bends. With the above steps, the operation section HP and the pressure adjustment section PC return to the initial states shown in FIGS. 1 to 3.

At this time, the operating fork 18 is rotated clockwise in FIG. 1 because the operating piece 17 pressed down by the biasing force of the first spring 20 is in contact with the tip of the arm 18a. There is. Therefore, the swinging arm 25 that contacts the operating fork 18 is also rotated clockwise, and the operating lever 17 is lifted. From then on, the operating lever 27
is held at the upper limit of the operating range by the biasing force of the first spring 20.

On the other hand, as shown in FIG. 1, the upper cover 3 is pivotally connected to a bracket 2b extending from the case 2 at its rear end portion by a pin 34, and can be opened and closed with respect to the case 2 by rotating in an arc. It is freely configured. The upper lid 3 is biased toward the open side by a torsion spring 35 pivotally supported by a pin 34, and is locked in the open/closed position by a locking member 36 of the case cover 2A. The lock is released by pushing the button.

It is formed in an opening that is closed by a. In this case, the liquid lift pipe 7 and the tea leaf storage case 32 for tea strainer are installed in the medium bottle 1 in an adjacent state, and the liquid lift pipe 7 is installed at a position eccentric from the center of the upper opening of the medium bottle.

On the other hand, a pneumatic pump P is provided between the upper member 3A and the lower member 3B of the upper lid 3, and this will be explained below.

The pump chamber 44 is moved between the lower member 3B and the annular pressure plate 43, which is provided inside the inner space of the upper lid 2 and can be moved vertically by a spring 48.
An operating push lid 46, to which an elastic bellows 45 is fixed, and which compresses the elastic bellows 45 via a pressure plate 43, is located within the cylindrical portion 3e formed at the center of the upper member 3A. It is provided so that it can rotate freely.

The operating push cover 46 and the cylindrical portion 3e of the upper member 3A are provided with stoppers 46a and 47a that overlap in the vertical direction at a specific position in the circumferential direction and prevent the push cover 46 from coming into contact with the push-down operation. Further, the upper lid 2 is provided with a lock state in which both the stoppers 46a and 47a overlap in the vertical direction, and a lock state in which both the stoppers 46a and 47a overlap in the vertical direction, by rotating the operating pusher cover 46 in a certain range around the vertical axis. 46

The pressure plate 43 is provided with a hook valve 51 that opens and closes its central through hole from below, and the spring 48 is interposed between the hook valve 51 and the upper surface of the lower member 3B. 43 and the push lid 46 are maintained in a standby position.

On the other hand, the lower member 3 is provided on the upper surface side of the inner stopper 5.
A vertically oriented nozzle 49 is formed that passes through B and faces into the space surrounded by the elastic bellows 45, and at the lower end of the vertically oriented nozzle 49, the medium bottle 1 is inserted.
An opening is formed that leads inside.

Therefore, when the pusher cover 46 is pushed in with the lock lever 47 switched to the unlocked position, the pusher cover 46 locks the hook valve 51.
At the same time, the pressure plate 43 is pushed down, and the elastic bellows 4
Compress the air surrounded by 5 and push it out. This pushed out air is guided into the medium bottle 1 via the vertical nozzle 49, once passing through the inside stopper 5 and the tea leaf storage case 32 for straining, and pushes down the liquid level inside the medium bottle 1. This pushed down liquid is transferred to the liquid pumping pipe 7,
The liquid flows out through the liquid guide pipe 8 and the liquid injection pipe 4.

In the figure, reference numeral 52 denotes a locking mechanism that locks the upper lid 3 in the closed state, and although not shown, lock release mechanisms protrude from both sides of the upper member 3A. Further, 53 in FIG. 6 is a heat insulating material.

By integrally forming the tea leaf storage case 32 for a tea strainer on the annular bracket 41 in this way, it is possible to supply liquid and insert tea leaves while the tea leaf storage case 32 for a tea strainer is attached to the outer case 2 side.
