Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an extractor, for example, an extractor for extracting the components of Japanese tea when drinking Japanese tea.

(Prior Art) Traditionally, teabags have been used that can be used to easily and conveniently brew Japanese tea, for example. As is well known, this tea bag is made from a paper bag and small pieces of tea leaves that are stored inside the bag.You can easily make tea by simply pouring hot water into the teacup containing the tea bag. It is something that can be done.

(Problem that the invention aims to solve) However, when the tea bag used in the past is taken out of the teacup after making tea, the hot water drips out because the tea bag itself contains a large amount of hot water. There was a problem that it was difficult to dispose of. These drips can stain the table, stain clothes, or stain the inside of the vehicle when drinking tea in a vehicle, such as a car, so it is preferable to minimize the drips.

Also, when making tea with a traditional tea bag,
Normally, tea is brewed by shaking a tea bag in a teacup, which has the problem that when the water temperature is high, the tea comes out well, but when the water temperature is low, it is difficult to make tea.

The purpose of this invention was to solve the above-mentioned problems with the conventional methods, by making it possible to minimize the amount of liquid dripping after the extraction of the components of the extracted material, and to efficiently extract the extracted material. The object of the present invention is to provide an extractor with a structure that

(Means for solving the problem) In order to achieve this object, the extractor of this invention includes a first clamping member and a second clamping member for clamping the material to be extracted in the liquid and applying a pressing force to the material to be extracted. A pressing force is applied between the two clamping members, the liquid permeable portion formed in one or both of the first and second clamping members, and the first and second clamping members in the direction of bringing these clamping members closer to each other. and a pressing portion that can freely maintain and release the pressing force.

In carrying out this invention, one or both of the first and second clamping members is restored to its shape so as to move these clamping members away when the pressing force between the clamping members is released. It is preferable to use an elastic member.

(Function) According to the extractor having such a configuration, the material to be extracted is held between the first and second holding members in the liquid, and the material to be extracted is removed by moving these holding members closer to or away from each other. A pressing force is applied to the material to be extracted, or the pressing force is released from the extracted material. By repeatedly performing such operations to squeeze out the components of the object to be extracted, the components of the object to be extracted can be efficiently extracted.

When the extraction of the components of the extracted material is completed, the liquid is removed from the extracted material by pulling up the extracted material from the liquid while applying a pressing force to the extracted material between the first and second holding members. The material to be extracted can be pulled up in the squeezed state, and dripping of the liquid can therefore be suppressed to a minimum amount. At this time, the material to be extracted is not held in a pressed state by sandwiching the material between the pressing part and the inner wall surface of a container such as a paper cup or teacup, but by using the first and second holding members. This is done by sandwiching the material to be extracted between the two.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings. Note that the drawings are merely shown schematically to the extent that this invention can be understood, and therefore, the dimensions, shapes, and arrangement positions of each component are not limited to the illustrated examples.

1 and the fitting part 24.

2A and 2B are side sectional views schematically showing the assembled state of the extractor of the first embodiment shown in FIG. FIG. 2B shows a state in which the gripping member is released and a state in which a pressing force is generated between the first and second clamping members. Further, FIG. 3 is a plan cross-sectional view of essential parts schematically showing a state in which the operating member is locked to the support member when the extractor of this embodiment is assembled.

As shown in FIG. 3, the operating member 1 of this embodiment
8 has locking portions 32 that are spaced apart from each other, and therefore, by inserting the support member 22 between the opposing locking portions 32, the operating member 18 can be freely slid on the support member 22. It can be locked to.

Next, the procedure for extracting the to-be-extracted material will be explained in order to better understand this idea.

First, in order to assemble the extractor 26, the operating member 18
is locked to the support member 22 (see FIG. 3). Next, the tip of the support member 22 is fitted into the fitting part 24, and the support member 22 is erected on the surface opposite to the clamping surface of the first clamping member 10 (FIGS. 1 and 2A,
(See B).

Next, the substance to be extracted 30 sandwiched between the first and second holding members 10 and 12 is placed in, for example, a teacup filled with hot water and immersed in hot water (not shown).

Next, the operation member 18 is operated to repeatedly generate or release a pressing force between the first and second clamping members 10 and 12. As shown in FIG. 2A, when no tension is applied to the connecting member 20, or even if it is applied, the tension is very small, the second clamping member 12 maintains its spherical shape. . At this time, the first and second holding members 10
No pressing force is generated between and 12 (pressing force released state). Although not shown, when the user puts the upright end A of the support member 22 against the palm of the hand and pulls up the operating member 18 with a finger, the operating member 18 moves along the support member 22 . As shown in FIG. 2B, this movement of the operating member 18 causes the operating member 18 and the first clamping member 10 to
When the first and second clamping members 10 and 12 are moved away from each other so that tension is applied to the connecting member 20, a pressing force that brings the first and second clamping members 10 and 12 closer to each other can be generated. As a result, the material to be extracted 30 is crushed between the first and second holding members 10 and 12, and thus the components of the material to be extracted 30 can be squeezed out. Thereafter, the user releases his/her finger from the operating member 18 and releases the pressing force between the first and second holding members 10 and 12. At this time, the second clamping member 12 tries to restore the spherical shape so as to move the clamping members away from each other, and the elastic force that tries to restore this shape helps release the pressing force (Figs. 2B and A). reference).

By repeatedly performing the operation of creating or releasing the pressing force between the first and second holding members 10 and 12 as described above, the components of the material to be extracted 30 can be efficiently extracted. For example, even when the water temperature is low, extraction can be carried out effectively. Further, the components of the extracted material 30 can be extracted in a shorter time, and the waiting time until the components can be extracted sufficiently to make tea, for example, can be reduced.

Moreover, after the extraction is completed, the first and second holding members 10
and 12, maintain the pressing force with your finger on the operating member 18, and take out the extracted material 30 from the teacup while squeezing out a large amount of hot water contained in the extracted material 30. , the amount of hot water that drips down can be reduced to a very small amount, and therefore the dripping of hot water can be reduced. With conventional tea cups and the like, hot water can be squeezed by pressing and holding the material to be extracted between the inner wall of the teacup and the pressing means, but in this case, the material to be extracted, which would be a hindrance to drinking tea, can be squeezed out immediately after the components have been extracted. To take out the hot water, you have to squeeze the hot water using the inner wall of the teacup, which is filled with enough hot water. However, it is troublesome to squeeze out the hot water from the inner wall of a teacup that is filled with hot water, and it is also difficult to squeeze out the hot water sufficiently. Also, if you squeeze the hot water from the empty inner wall of the teacup after drinking the tea, the extracted material will be immersed in the hot water until you finish drinking the tea, making the tea stronger than necessary. Extractable substances interfere with drinking tea. However, in this embodiment, the material to be extracted is transferred to the extractor 26.
Since the pressure is applied between the clamping members 10 and 12 constituting the teacup, the hot water of the extracted material can be squeezed out without pressing the extracted material against the inner wall surface of the teacup. Therefore, even if there is a lot of hot water in the teacup, it is possible to squeeze out the hot water for the extracted material by dropping the squeezed hot water into the teacup, and not only can the amount of hot water dripping be greatly reduced compared to the conventional method, Squeezing hot water is also easier than before. Therefore, after extracting the components, the hot water of the extracted material can be quickly and easily squeezed out to eliminate dripping or reduce the amount of hot water as much as possible, and the extracted material can be taken out of the hot water.

In addition, in conventional teabags, etc., when a flexible container that is easily deformed by external force, such as a paper cup, is used, if the material to be extracted is squeezed by pressing it against the inner wall of the flexible container, the deformation of the container may cause the material to be extracted to be squeezed out. There is an inconvenience that it is difficult to squeeze. However, in the first embodiment, it is possible to press and release the material to be extracted without pressing the material against the inner wall surface of the container, thereby eliminating the above-mentioned inconvenience.

For example, when making coffee or tea,
It can also be used to stir sugar or milk.

Second Embodiment Figure 4 is for explaining the second embodiment of this invention.
FIG. 3 is a perspective view showing an extractor of a second embodiment and a material to be extracted to be extracted by the extractor in the same drawing, and an exploded view of each component of the second embodiment. 34 and 36 indicate first and second clamping members, and in this embodiment, the second clamping member 36 is
It is constructed using an elastic member. This second holding member 3
Although the shape of the second clamping member 6 is not limited, the second clamping member 36 in this embodiment has a shape that curves like the side surface of a cylinder when the pressing force between the first and second clamping members 34 and 36 is released. It has a shape that is convex from the clamping surface of the material to be extracted to the side opposite to the clamping surface.

38 indicates a liquid permeation part, and in this example,

Reference numerals 46 and 48 indicate locking portions, and in this embodiment, the locking portions 46 and 48 are provided facing each other on the side of the first clamping member 34 that holds the object to be extracted. The abutting portion 44 is disposed between the locking portions 46 and 48, and the operating member 42 is locked on one side by the locking portion 46 and on the other side by the locking portion 48. , the operating member 42 is removably and rotatably locked.

0 mentioned above, the first and second clamping members 34 and 36
, a transparent section 38 , and a pressing section 40 .

Next, the procedure for extracting the to-be-extracted material will be explained in order to better understand this idea.

5A and 5B are main part sectional views schematically showing the assembled state of the extractor of the second embodiment shown in FIG. FIG. 4B shows a state in which the pressure is released and a state in which a pressing force is generated between the first and second clamping members.

First, in order to assemble the extractor 50, in this embodiment, the container 28 containing the object to be extracted 30 and the second clamping member 36 are sequentially arranged from the first clamping member 34 side. At the same time, the storage body 28 and the second holding member 36 are sandwiched between the first holding member 34 and the pressing part 36, and the operating member 42 of the pressing part 36 is held in place by the locking parts 46 and 48. One clamping member 34 (FIGS. 4 and 5 A and B)
reference).

Next, the substance to be extracted 30 sandwiched between the first and second holding members 34 and 36 is placed, for example, in a teacup filled with hot water (this teacup is indicated by the reference numeral 52 in the figure) and soaked in hot water. .

Next, the operating member 42 is rotated so as to press the first clamping member 34 against the inner surface of the teacup 52 to create a pressing force between the first and second clamping members 34 and 36. Repeat the process to release it. As shown in FIG. 4A, when the abutment part 44 is not in a state where it stands up against the second clamping member 36 but is in a state where it falls down along the second clamping member 36, the second clamping member 36 is Maintains a curved shape like the side of a cylinder. At this time, no pressing force is generated between the first and second holding members 34 and 36 (pressing force released state). Further, as shown in FIG. 5B, when the operating member 42 is rotated so that the contact portion 44 stands up against the second clamping member 36, the first and second clamping members 34 and 36 are brought closer to each other. It is possible to generate such a pressing force. As a result, the substance to be extracted 30 is transferred to the first and second clamping members 34
and 36, and thus the extracted material 30
It is possible to extract the components of Thereafter, the operating member 42 is rotated to release the pressing force between the first and second clamping members 34 and 36. At this time, the second clamping member 36 attempts to restore the curved shape such as the cylindrical side surface so as to move these clamping members away from each other, and the elastic force that attempts to restore this shape helps release the pressing force. (See Figures 5B and A).
After the extraction is completed, the material to be extracted 30 is removed from the hot water while keeping the pressed state of the material to be extracted 30 in such a state that the abutting portion 44 stands up against the second holding member 36. Drips can be kept to a minimum.

In this second embodiment as well, even if there is a lot of hot water in the teacup, the hot water to be extracted can be squeezed out by dropping the squeezed hot water into the teacup, and the dripping of hot water is much easier than before. Not only can the amount of hot water be reduced, but the hot water can also be squeezed out more easily than before. Therefore, after extracting the components, the hot water of the extracted material can be quickly and easily squeezed out to eliminate dripping or reduce the amount of hot water as much as possible, and the extracted material can be taken out of the hot water.

FIG. 6 is a front view showing a modification of the transparent part.
In the figure, 54 indicates a liquid permeation part. As shown in the figure, the transparent part 54 is connected to the second holding member 3, for example.
It may also be configured with a notch formed in 6.

Third Embodiment FIGS. 7A and 7B are partially cutaway side sectional views schematically showing the structure of an extractor according to a third embodiment of this invention, and FIG. 7A is a first and second clamping FIG. 7B shows a state in which the pressing force between the members is released, and a state in which the pressing force is generated between the first and second clamping members. In order to explain the third embodiment, the extractor of the third embodiment and the material to be extracted by the extractor are shown in the same drawing in FIGS. 7A and 7B. Note that the same components as those of the first or second embodiment described above are designated by the same reference numerals.

First, the configuration of the third embodiment will be explained with reference to FIG. 7A. In FIG. 7A, 56 indicates a first holding member and 58 indicates a pressing portion. In this example,
The pressing portion 58 is composed of the operating member 18, the connecting member 61, and the supporting member 60. Although the cross-sectional shape of the support member 60 does not matter, in this embodiment, the support member 6
0 has the same cross-sectional shape as the support member 22 of the first embodiment (see FIG. 3), so that the locking portion 3
2, the operating member 18 is slidably engaged with the support member 60. Support member 60
has an approximately J-shape with one end bent;
When forming a pressing force between the first and second clamping members 56 and 36, the bent end P of this support member 60 presses the second clamping member 36.

Reference numeral 62 indicates a mounting portion, and reference numeral 64 indicates a mounting shaft. In this embodiment, the mounting portion 62 is provided protrudingly on the side of the first clamping member 56 that clamps the object to be extracted, and the mounting shaft 64 is configured to protrude laterally. It is provided in the mounting part 62. In this embodiment, the support member 60 is rotatably and detachably fixed by inserting the mounting shaft 64 into a through hole provided near the bent end P of the support member 60. At the same time, one end of the connecting member 61 is fixed to the operating member 18 and the other end is fixed to the first holding member 56. By operating the operating member 18 to pull up the portion of the first clamping member 56 to which the other end of the connecting member 61 is fixed, the second clamping member 36
can be pushed at the bent end P.

66 indicates an extractor, in this example extractor 6
6 is composed of first and second holding members 56 and 36, a transparent section 18, and a pressing section 58.

Next, the procedure for extracting the to-be-extracted material will be explained in order to better understand this idea.

First, the bent end portion P is inserted between the locking portions 32 to lock the operating member 18 to the support member 60. Thereafter, the container 28 containing the substance to be extracted 30 is sandwiched between the first and second holding members 56 and 36, and then the support member 60 is fixed to the mounting shaft 64.

Next, the substance to be extracted 30 is placed in, for example, a teacup (not shown) filled with hot water and immersed in hot water.

Next, the operation member 18 is operated to repeatedly generate or release a pressing force between the first and second holding members 56 and 36. As shown in FIG. 7A, when the operating member 18 is close to the bent end P side to the extent that the bent end P does not push the second clamping member 36, the second clamping member 12 is moved like a cylindrical side surface. Retains curved shape. At this time, no pressing force is generated between the first and second holding members 56 and 36 (pressing force released state). Although not shown, when the other end B of the support member 60 is placed on the palm of the hand and the operating member 18 is pulled up with a finger, the operating member 18 moves along the support member 60. As shown in FIG. 7B, as the operating member 18 moves, the portion of the first clamping member 56 to which the other end of the connecting member 61 is fixed is pulled up, so that the second clamping member 36 is moved to the bent end. Pressed in part P. Therefore, it is possible to generate a pressing force that brings the first and second holding members 56 and 36 closer to each other. As a result, the material to be extracted 30 is crushed between the first and second holding members 56 and 36, and thus the components of the material to be extracted 30 can be squeezed out. Thereafter, the user releases his/her finger from the operating member 18 and releases the pressing force between the first and second holding members 56 and 36. At this time, the second clamping member 36 tries to restore the curved shape like the cylindrical side surface so as to move these clamping members away from each other, so the elastic force that tries to restore this shape helps release the pressing force (7th (See Figures B and A).

This third embodiment also provides the same effects as the first embodiment.

This invention is not limited to the above-described embodiments, and the shape, arrangement position, and configuration of each component can be modified and changed as desired according to the design.

For example, the shape and configuration of the first and second clamping members can be any suitable shape and configuration that allows the material to be extracted to be held between the clamping members during extraction.

Furthermore, in the above-mentioned embodiment, an example was explained in which only the second clamping member was composed of an elastic member.
Only the first clamping member may be constructed of an elastic member, or both the first and second clamping members may be constructed of elastic members. Furthermore, the elastic member may be configured to have a curved shape or a planar shape that curves in any suitable manner when the shape is restored. When the elastic member has a planar shape, for example, the second clamping member is made of an elastic member, and the peripheral part of the second clamping member is supported by a locking part protruding from the peripheral part of the first clamping member. The pressing force may be generated by pressing the central portion of the second holding member.

Further, the transparent portion may be provided only on the first holding member, only on the second holding member, or may be provided on both the first and second holding members. Further, the permeable portion may have any suitable structure such as openings, pores, holes, slits, notches, meshes, etc., as long as the liquid can freely pass therethrough.

Further, the configuration of the pressing portion can be any suitable shape capable of applying a pressing force between the first and second holding members.

For example, the pressing section may include a first pressing member, a second pressing member, and an elastic means such as a coil spring or a leaf spring provided between one end of these pressing members, and one of the first pressing members and A structure may be adopted in which the portion between the other end and the portion between the one and the other ends of the second holding member are rotatably connected. In this case, the first clamping member is the first or second holding member, and the second clamping member is the second or first holding member,
Preferably, they are attached removably. By pinching one end of the first and second holding members with your fingers and bringing them closer together, you can move the first and second holding members away from each other and release the pressing force between these holding members, and then release your fingers. The elastic force of the elastic means can generate a pressing force in a direction in which the first and second holding members approach each other. In this case, both the first and second holding members need not be made of elastic members.

Alternatively, the pressing portion may be formed of an elastic body that is bent at the center into a U- or V-shape, for example. In this case, the first clamping member is attached to one end or the other end of the elastic body, and the second clamping member is preferably detachably attached to the other end or one end of the elastic body. Attach. By pinching the bending elastic body with fingers so as to bend it further, a pressing force is generated between the first and second holding members in a direction that moves these holding members closer to each other. Further, when the finger is released, the first and second holding members are moved away from each other by the restoring force of the elastic body, and the pressing force between these holding members is released. In this case, both the first and second holding members need not be made of elastic members.

In addition, in the above-mentioned embodiment, an example was explained in which the material to be extracted was placed in a container and the components were extracted.
It is not necessary to put the substance to be extracted into the storage body, and if not, the size of the permeation part is set to any suitable size that can hold the substance to be extracted between the first and second clamping members, and when performing component extraction. It is preferable to prevent the substance to be extracted from flowing outside between the first and second clamping members. The material to be extracted may be processed into powder, granules, strips, or any other suitable shape.

Further, the extractor of this invention may be used to extract the components of any material to be extracted, and the liquid used for component extraction is not limited to hot water, and any liquid may be used. When hot water is used, it is preferable to prevent the temperature of the hot water from decreasing by reducing the heat capacity of the extractor. The heat capacity of the extractor can be reduced, for example, by constructing each component with thin members.

(Effects of the invention) As is clear from the above description, the extractor of this invention allows repeated operations to generate or release a pressing force between the first and second holding members. Since the components of the object to be extracted are squeezed out in this way, the components of the object to be extracted can be efficiently extracted.

When the extraction of the components of the extracted material is completed, the liquid is removed from the extracted material by pulling up the extracted material from the liquid while applying a pressing force to the extracted material between the first and second holding members. The material to be extracted can be pulled up in the squeezed state, and dripping of the liquid can therefore be suppressed to a minimum amount. Moreover, even if there is a lot of liquid in a container such as a teacup, the liquid to be extracted can be squeezed out by dropping the squeezed liquid into the container, which greatly reduces the amount of liquid dripping compared to conventional methods. It is also easier to squeeze out the liquid than in the past. Therefore, after extracting the components, the liquid to be extracted can be quickly and easily squeezed out to eliminate dripping of the liquid or to minimize the amount of liquid, and to take out the substance to be extracted from the liquid.

This device is particularly suitable for use as a disposable extractor for making drinks such as Japanese tea, black tea, coffee, or Chinese herbal medicine.For example, when brewing Japanese tea, black tea, etc. using low-temperature hot water. , it is possible to shorten the time. In addition, since the amount of liquid dripping can be kept to a minimum, there is no risk of liquid dripping staining the table, clothes, or staining the inside of a vehicle such as a car when drinking tea. However, it becomes less.
