Description

The present invention relates to a tea machine with a lid used for brewing tea using a tea bag.

  In order to leach dry beverages such as tea, tea utensils such as teapots, teapots, and teacups are usually used. In addition, a method for obtaining a leachable liquid of a dried beverage includes a method of obtaining a leachate by directly leaching the tea leaves in a tea container and a tea bag in which tea leaves are sealed in a water-permeable bag such as a nonwoven fabric. The method of obtaining is common. Hereinafter, tea leaves will be described as examples of problems in the current state of the brewing method for dried beverages and improvement measures according to the present invention.

  In the method of brewing the green tea leaves in the teapot, the green tea leaves diffuse in the teapot, so the leaching of the soluble content becomes uniform, the pour-out is good, and the flavor can be leached. However, it must be thoroughly washed each time it is used in order to prevent the propagation of germs when the tea leaves are stuck or clogged in the filter net in the teapot. Moreover, the processing of the tea husk is cumbersome and the work of collecting it as trash is troublesome. When weighing tea leaves and putting them in the teapot, we must be careful not to spill tea leaves. To make them delicious, it is necessary to use the appropriate amount of tea leaves. Requires skill.

  On the other hand, in the method using a tea bag, since tea leaves are enclosed in a water-permeable bag, handling is easy and no tea strainer is required when pouring, and teapot cleaning and cleaning of tea leaves are easy. In addition, since tea leaves are quantified in advance in the production process, it is not necessary to worry about the measurement of tea leaves, and tea can be easily brewed.

  However, in the leaching with the tea bag, the tea leaves are contained in the bag, so that the leaching of the soluble components from the tea leaves does not occur quickly, and it takes time for the leaching. In addition, when pouring a teapot, even if the teapot is tilted, the high concentration of exudate remains in the tea leaves that have absorbed and expanded in the bag, so there is not enough leaching of solubles compared to Sanyu tea leaves, and generally drowning. The light blue color is thin and the flavor is poor.

  Therefore, if you press the tea bag with the bottom of the teaspoon to drain the tea bag and drain it, if the pressure is too strong, the tannin is excessively extracted from the tea leaves, and the bitterness and astringency will increase. It has a big effect. Thus, it is effective to squeeze tea bag tea by moderate pressing, and the strength of the pressing greatly affects the quality.

  Also, if both the tea leaves and tea bags are kept in the exudate for longer than necessary, the elution of tannin will progress and the exudate will have a strong bitter taste. Must be. In particular, the tea bag is insufficiently squeezed, and if a high-concentration exudate remains in the tea leaves in the tea bag, the quality of the tea leaves deteriorates, and the flavor after the second tea is reduced.

Tea bags for tea bags are usually finely crushed in order to promote leaching of the soluble content of tea leaves in the bag and to facilitate quantitative charging during bag packaging. Since fermented tea such as black tea has already been oxidized in the tea making process, its impact on quality due to crushing is relatively small. However, in non-fermented tea such as sencha, crushing after tea production promotes the oxidation of the product, so the leachate Will greatly impair the light blue color, aroma and taste quality. For this reason, crushing should be avoided as much as possible when making non-fermented tea into tea bags, but when tea leaves are enclosed in tea bags without crushing, steaming and swallowing the raw leaves stiffened the volume. When dried tea leaves are soaked in hot water, the bulk of the tea leaves expands to return to the original shape of the original leaves, the leaves cannot expand sufficiently in the tea bag, and become a sponge that absorbs water in a saturated state. The leaching of soluble components to the outside does not proceed. For this reason, tea bags are not suitable for high-quality senchas, and the current use of tea bags in sencha is limited to inexpensive and low-quality tea bags.

  In addition, the tea leaves when pouring are usually in a state where both the tea leaves and tea bags are soaked in the leachate in the teapot. It becomes thicker as the water-soluble matter dissolves. For this reason, when pouring into several cups, it is necessary to pour it over and over again to make the concentration uniform.

  When drinking tea bags directly in drinking containers such as teacups and tea cups, the tea bag has a light blue color and poor flavor, and it cannot be drunk after the 2nd round.

  From the above, in order to make it easy and easy for everyone to brew high quality tea leaves, use a tea bag to reduce the squeeze during pouring, which is a disadvantage of tea bags. It is the best method to obtain a tea cup that can be accurately and does not retain the tea bag after leaching in the liquid.

  Regarding the method of pressing the tea bag in the teapot, Patent Literature 1 discloses a vertically movable method using a pressing piece and a lever method in which a handle is gripped and a compression plate is pressed against the inner wall of the teapot via a connecting member. A system is disclosed in which a tea bag that has absorbed water in a container for a disposable cup is pulled up on the liquid level in the container below the cover and hung in the vertical direction, and squeezed on both sides by the wing part. A teapot having a structure in which tea leaves that have finished leaching by tilting the teapot and leaving it in contact with the liquid surface is disclosed.

JP-A-1-227714 Special table 2007-501743 JP 2008-43715 A

In the method of moving up and down using a pressing piece and the lever method in which a handle is held and a compression plate is pressed against the inner wall of a teapot via a connecting member, a plurality of tea bags are mechanically operated in hot water poured into the teapot. The aim is to promote the exchange of water inside and outside the tea bag by pressing it once, and is intended to cope with a material with poor water permeability. However, tea bag materials currently used are mainly non-woven fabrics with high water permeability and nylon / polylactic acid nets, and the water permeability of tea bags has been improved. In these materials, tea leaves have expanded to include hot water. The challenge is how to properly and easily drain tea bags. Moreover, in the technique of patent document 1, since the tea bag at the time of pouring is in the teapot hot water, the tea leaf in the tea bag is deteriorated in quality, and the quality after the second tea is also deteriorated. In addition, it is necessary to continue pressing mechanically at the time of pouring out, the operation is inconvenient, and the pressing mechanism is composed of multiple parts. There is a concern that foreign materials are mixed in due to wear pieces of material at the contact portion, and the manufacturing cost also increases. In both of the embodiments described in Patent Document 1, there are overhanging members such as a spring, a connecting member, and a handle, and the operational feeling and aesthetics of the teapot are impaired.

  In the lid that assumes the disposable cup described in Patent Document 2, the tea bag that has absorbed water in the container is pulled up on the liquid level in the container below the lid and hung in the vertical direction. In order to hang the tea bag vertically without touching the liquid surface, the body part of the lid must be lengthened, the internal volume of the lid becomes large and the heat retention effect is reduced. In teapots, etc., tea bags are too large to be practical. Further, in order to squeeze the tea bag, it is necessary to sandwich the wing with two fingers. In addition, since the wing closes like a hinge, it can not be pressed uniformly, and there is no mechanism to hold both wings in a certain gap, so if the finger pressure is strong, the tea bag will be squeezed too much, and conversely if the pressure is weak, the squeezing will be insufficient It is difficult to obtain a predetermined concentration.

  The teapot described in Patent Document 3 has a structure in which tea leaves that have been leached out by tilting the teapot and standing still do not touch the liquid surface, but this method cannot squeeze the tea bag. In addition, when there is a large amount of residual liquid in the teapot, the tea leaves are immersed in the liquid, and when the residual liquid is poured, the tea leaves may be immersed again in the liquid.

  SUMMARY OF THE INVENTION In view of the above-described drawbacks of conventional tea bags for tea bags, the present invention provides a tea machine for extraction that can be easily and satisfactorily poured by a simple mechanism and that does not retain the tea bag after leaching. It is an object.

  A tea machine with a lid according to a first aspect of the present invention is a tea machine with a lid for leaching a dried plant that has entered a tea bag, and has a drainer between an opening of the upper part of the tea machine and an assumed liquid surface, The bottom surface of the lid in a closed state and the drainer at any of the locations is characterized by maintaining a substantially constant gap.

A tea machine with a lid according to a second invention is the tea machine with a lid according to the first invention, characterized in that the drainer can be attached and detached.

The tea machine with a lid according to a third aspect of the invention is the tea machine with a lid according to the first and second aspects, wherein the gap between the bottom surface of the lid and the draining can be adjusted.

With the configuration as described above, the tea set of the present invention has the following effects. In the tea apparatus with a lid according to the first aspect of the present invention, the lid bottom surface and draining top surface are kept substantially horizontal and parallel when the lid of a teapot, teapot or teacup is closed, and the gap is defined. By placing the tea bag that has absorbed the hot water and inflated it flat on the draining top and completely closing the lid, the sandwiched tea bag can be uniformly squeezed to the specified thickness by pressing the lid. A leachate having a concentration of The tea bag can be pressed to obtain a predetermined pressure on the tea bag simply by closing the lid. In addition, when the lid is not completely closed but is stopped halfway, the tea bag squeezing degree becomes light, so that the concentration of the leachate can be adjusted thinly by adjusting the lid.

Since the drainer is arranged at a position higher than the assumed level of the leachate, the squeezed tea bag is not immersed again in the leachate and does not affect the quality of the leachate. Because the exudate that has been drained from the tea bag properly becomes homogeneous, it does not need to be poured over and over again, and even if the exudate is kept in the tea container, there is no deterioration in quality due to tea bag immersion. It can also be used as a pot. When pouring a teapot or teapot, the lid is poured with a finger, so that the tea bag sandwiched between the drainer and the bottom of the lid does not fall into the tea set. After the 2nd round, the same effect as the 1st round can be obtained by returning the tea bag to the bottom of the teapot and pouring hot water again.

The tea apparatus with a lid according to the first invention can solve the problem that the tea bag after leaching pointed out as a problem of Patent Document 1 remains in the infusion liquid of the tea apparatus. In addition, it is possible to solve the decrease in heat retention and the appearance defect due to the method of squeezing the vertical tea bag pointed out as the problem of Patent Document 2 by the method of squeezing in a substantially horizontal state. The tea bag can be squeezed with a uniform pressure because the pressure is not a biased pressure but a parallel pressure. The problem pointed out as the problem of Patent Document 3 that the tea bag cannot be squeezed, and that the tea bag is again immersed in the leachate when pouring can be naturally solved.

The detachable drainer of the tea apparatus with a lid according to the second aspect of the invention can secure a set gap by being mounted at a predetermined position and plays a role of appropriately squeezing the tea bag. By removing it after use, the teapot, teapot, and teacup can be easily cleaned and the inside of the teaware can be kept clean. In the case of a cup, since the drainer may touch the nose of the drinker when drinking, a detachable drainer that can be temporarily removed from the cup together with the tea bag that is placed is more practical.

According to a third aspect of the present invention, there is provided a spacer on the inner lid for lid or on the inner brim for draining, or by using a lid having a plurality of different thicknesses on the back surface, Since the gap between the tea bags can be adjusted, a variety of tea bags with different tea bag shapes, tea leaf types, and contents can be accommodated with a single teapot. When a lid having a plurality of different thicknesses on the back surface is used, it is convenient because the gap can be adjusted only by rotating the lid.

Drainer is removable and a teapot using a spacer. A spacer is placed on the draining inner collar, a drainer is placed on top, a tea bag is placed on top of it, and the lid is covered. It is a block diagram. It is sectional drawing of FIG. The drainer is detachable, and the water drainer with a spacer is used to place the drainer on the draining collar, place a tea bag to be pressed on it, place the spacer on the lid lid, and cover the lid. It is a block diagram which shows the state. FIG. 4 is a cross-sectional view of FIG. 3. It is a perspective view of the teapot with which the drainer was integrated with the lid which was divided into 3 equally from the center part of a lid, and each has a different thickness. It is a perspective view of the lid of a teapot provided with the mark which shows the degree of a press on the surface of the lid | cover of FIG. It is a block diagram which shows the state which drained the drainage with the teapot, and sandwiched the spacer on the lid collar and covered the lid with the teapot using the spacer. It is a perspective view which shows the state which accommodated the tea bag in the teapot provided with the guide and the string thread. It is a perspective view which shows an example of the hanging-type detachable drainer which can be used with a ready-made teapot and a cup.

Hereinafter, embodiments of a tea machine with a lid according to the present invention will be described with reference to the drawings. However, the technical scope of the present invention is not limited to the specific applications, shapes, dimensions, and the like shown in the following embodiments.

1 is a configuration diagram of a removable drainer according to Embodiment 1 of the present invention, and a teapot in which a spacer is sandwiched between the drainer and the lid, and FIG. 2 is a sectional view thereof. The drainer 3 has a substantially half-moon shape along the inner peripheral wall of the teapot 1 and has a size on which the tea bag 4 enclosing tea leaves for the number of people can be placed almost flat, and is provided with a small hole 10 for drainage. . The teapot opening which is not blocked by draining is a space for taking in and out the tea bag 4 and pouring water. The drainer 3 is located in a fixed position by the horseshoe-shaped drainer inner collar 6 and the rotation stop projection 7 which are in the facing direction of the spout at the upper part of the inside of the teapot 1 and are higher than the assumed liquid level 5. At this time, in any place in the drainer, the bottom surface of the lid 2 in the closed state and the drainer 3 are maintained with a substantially constant gap, and when the shape of the bottom surface of the lid is convex or concave, the drainer The top surface also has a concave or convex shape that matches the bottom of the lid. In the embodiment of the present invention, the drainer is removable, but may be a drainer integrated with the teapot.

A method for leaching a dried plant contained in a tea bag by a teapot with a lid provided with a drainer of Example 1 of the present invention is described below. When the tea bag 4 is leached, first, an appropriate amount of hot water is poured into the teapot 1 from the teapot opening in the facing direction of the drainer 3 and allowed to stand for about 1 minute to warm the teapot 1 and lower the hot water temperature to an appropriate temperature. Thereafter, the tea bag 4 is thrown into the bottom of the teapot using the attached string 9, and the string 9 is moved out of the teapot 1 and the lid 2 is closed. In this state, tea leaves are leached out, and after a suitable time has elapsed, the lid 2 is opened and the tea bag 4 is placed flat on the drainer 3 using the string 9. Thereafter, the string 9 is hung out of the teapot, the lid 2 is lowered in the vertical direction, and the lid 2 is completely closed. By fully closing the lid 2, the tea bag 4 is squeezed at a predetermined gap, so that excess leachate falls into the teapot or obtains an appropriate concentration of leachate. Next, the teapot 1 is lifted, fingers are put on the lid 2, and poured into each cup. If the leachate remains, it may be poured again into an empty cup or left in the teapot for the second pot. When drowning the second rice, first open the lid 2, use the string 9 to move the tea bag 4 placed on the drainer 3 from the opening to the bottom of the teapot, drop the string 9 outside the teapot 1, Hot water is poured from the opening and the lid 2 is closed again. By repeating in this way, in the case of Sencha, it can be deliciously tasted up to several rice crackers. Since the tea bags that have been drunk are already drained, they do not drain or fall off and are easy to clean.

The teapot teapot provided with the drainer of Example 1 of the present invention can control the pressure on the teabag by using a spacer. When it is desired to increase the pressure, the drainage 3 is positioned by the thickness of the horseshoe spacer 11 by sandwiching the horseshoe spacer 11 between the drainage inner collar 6 and the drainage 3 arranged on the side opposite to the spout 8. The gap between the lid 2 and the bottom surface of the lid 2 is narrowed, and the pressure can be increased. Conversely, when it is desired to weaken the pressure, if the ring spacer 13 is sandwiched between the lid collar 12 and the lid 2, the position of the lid 2 is increased by the thickness of the ring spacer 13 while maintaining a sealed state. A gap with the bottom surface of the lid 2 is widened, and the pressure can be weakened. By increasing the number of these spacers or using spacers having different thicknesses, an optimal leachate can be obtained with a single teapot for various packaging materials, shapes, tea leaf quantities, and tea quality tea bags. In addition, the first sengo can be extracted lightly so that the scent will stand out, and the second senme can be added to or modified with a spacer to enjoy a strong squeezed taste.

FIG. 3 is a configuration diagram of a detachable drainer according to Embodiment 2 of the present invention, and a hot water scum with a spacer sandwiched under the lid, and FIG. 4 is a cross-sectional view thereof. In the case of hot water, the tea bag 4 is for one person and the spacer is small, and the spacer is arranged at a position facing the smooth drinking mouth without the drain collar and lid collar. Others are the same as the teapot of Example 1.

In a water bath, the spacer may touch the nose when tilted depending on the shape. At this time, before drinking, the lid 2 of the hot water cup 14 is opened, the knob 16 of the drainer 3 is pinched with a finger, the drainer 3 and the tea bag 4 are lifted as a set, and temporarily placed outside the hot water bottle. At the time of drinking, it is easy to drink from a smooth drinking mouth 15 where the inner peripheral wall of the lid 14 is not attached to the inner peripheral wall of the cup 14 facing the drainer 3. When putting the second cross, the draining knob 16 of the temporarily placed drainer 3 is pinched with a finger, the tea bag 4 placed on the drainer 3 is lifted together, the drainer 3 is set at a predetermined position of the hot water cup 14, and the tea bag 4 Using the string 9, the tea bag 4 is transferred to the bottom of the hot water cup 14, the string 9 is moved out of the hot water cup 14, and the second bath is poured. Since the tea bag 4 that has been drunk has already been drained, it is easy to clean up without dripping or dropping.

FIG. 5 shows the teapot of Example 3 of the present invention having a lid that is integrated with the teapot and radially divided into three from the center of the lid and having different thicknesses, and FIG. 6 shows the thickness of the back surface of the lid. Indicates the surface of the lid with the mark on the surface. When the inflated tea bag 4 is placed on the drainer and the lid 2 is closed with the strong pressure surface 17 having a thick lid bottom, the gap between the two becomes narrow and the pressure on the tea bag 4 increases. Conversely, when the lid 2 is closed with the low-pressure surface 19 having a thin lid bottom surface, the gap between the two is widened and the pressure on the tea bag 4 is weakened. When intermediate pressing on the tea bag is required, the medium pressure surface 18 on the back of the lid is selected. The shape of the drainer 3 when using the lid 2 is preferably a shape that matches the radial surface of the back surface of the lid and is provided on the inner wall of the teapot diagonal to the spout 8. In the third embodiment of the present invention, an example in which three types of pressing can be selected only by rotating the lid 2 by equally dividing the back surface of the lid into 120 degrees and securing three levels of thickness is shown. The thickness may be divided into two levels. Further, when the tetra-type tea bag is exclusively used, the bottom face angle of the tetra-type is 60 degrees, so that the lid bottom face can be divided into 60 degrees at a maximum to constitute 6 levels of thickness. Moreover, by marking the mark 21 indicating the thickness of the bottom surface of the lid on the lid surface, it is possible to select a desired press without confirming the bottom surface of the lid each time.

FIG. 7 shows a teapot in which the drainer is integrated with the teapot body and a spacer is used. The gap between the drainer 3 and the bottom of the lid 2 can be arbitrarily enlarged by sandwiching the ring-shaped spacer 13 on the inner lid 12 for the lid in the teapot 1. The teapot with which the drainer is integrated with the main body of the teapot has no looseness because the drainer is fixed, and the drainage is not lost. Moreover, an integrated design can be obtained.

FIG. 8 shows a teapot provided with a guide 22 and a string passage groove 23 for preventing the corner of the tea bag from protruding when draining. A normal tea bag has a cushion shape and a rectangular bottom, and when placed on a substantially half-moon drainer, the outer corner of the tea bag 4 may protrude from a circular teapot opening or a cup opening. In order to prevent this, a pair of guides 22 having a shape in which the inner lid 12 for the lid partially protrudes substantially inwardly is provided, and a string passage groove 23 for passing the string 9 connected from the vicinity of the center to the upper part of the peripheral wall of the tea device is provided. It is provided. In use, the tea bag 4 that has absorbed water and expanded is placed on the drainer 3 using the string 9, and the tea bag 4 is pulled outward by guiding the string 9 to the groove 23 and pulling the string 9 outward. Thus, both shoulders of the tea bag 4 are pushed by the guide 22, drainer 3, the lid 2, and the inner peripheral wall of the tea pot tea device 1, and are contracted in the center direction of the tea bag 4 to prevent the tea pot tea device 1 from protruding.

FIG. 9 shows a hanging drainer that can be used in a teapot and a teacup for an existing tea leaf as a removable drainer. In this method, a draining suspension support 24 is placed on the lid lid 12 of the teapot 1 or the cup 14, and the lid bottom surface and draining water when the lid is closed at a position higher than the liquid level 5 assumed thereby. The drainer 3 is disposed at a position where the gap on the top surface is a predetermined interval. The hanging type drainer can be retrofitted, and the clearance can be adjusted by using the lid ring spacer 13 together. When the shape of the bottom surface of the ready-made teapot or cup is convex or concave, the draining top surface may be adjusted to be concave or convex according to the bottom surface of the lid.
