  Hereinafter, the extraction netting tool and the extractor according to the embodiment will be described. Here, an explanation will be given with an example assuming a teapot, which is a tool for brewing tea as an extractor. FIG. 1 is an exploded perspective view showing a teapot 10 according to the embodiment, and FIG. 2 is a cross-sectional view of the teapot 10.

  This teapot 10 is a device for extracting beverage components such as tea components and coffee components from an extract (for example, tea leaves such as Japanese tea or black tea, coffee, etc.), that is, a device for producing a beverage. It is.

  The teapot 10 includes a container 20 as an extraction container, a lid 12, and an extraction netting tool 30.

  The container part 20 includes a container main body part 22, a spout part 28, and a handle part 29.

  The container body 22 is formed in a container shape having an opening 27 on the upper side. More specifically, the container body portion 22 has a thick middle in the height direction and is formed in a container shape whose upper and lower portions are thinner than the intermediate portion, and can store liquid therein. Yes.

  The outer surface of the bottom 23 of the container body 22 is formed in a shape that can be placed on a flat surface such as a desk. The inner surface of the bottom 23 is formed in a shape that can stably support the extraction netting tool 30, here, flat. The inner surface of the bottom 23 is preferably a surface that is the same as or wider than the lower portion of the extraction netting tool 30.

  The opening 27 opens upward above the container body 22. Then, the liquid is poured into the container main body 22 through the opening 27, and the liquid can be stored in the container main body 22.

  The height position of the opening 27 from the inner surface of the bottom 23 is preferably the same as the height dimension of the extraction netting tool 30. As a result, the upper end of the extraction mesh tool 30 can be disposed in the opening 27 and supported at a fixed position, and the opening 27 can be closed with the lid 12 while the extraction mesh tool 30 remains set. Because it can. Further, the inner diameter of the opening 27 is formed to a size that allows the extraction netting tool 30 to be inserted. The inner diameter of the opening 27 is preferably about the same as the outer diameter of the extraction netting tool 30. This is because the extraction net tool 30 can be supported as little as possible.

  The spout part 28 is a part of the outer periphery of the container main body part 22 and is formed in a cylindrical shape extending obliquely upward from an intermediate part in the height direction. The base end portion of the spout portion 28 communicates with the internal space of the container body portion 22. And if the container main-body part 22 is inclined so that the front-end | tip part of the spout part 28 may face downward, the liquid in the container main-body part 22 will flow out through the spout part 28 outside. The spout portion may have a semi-cylindrical shape extending outward from the peripheral edge of the opening of the container main body. That is, the spout portion 28 may be configured to guide the liquid in the container main body portion 22 to the outside.

  The handle portion 29 is a part of the outer periphery of the container main body portion 22 and is formed in a cylindrical shape extending obliquely upward from an intermediate portion in the height direction. Here, in the plan view of the container main body 22, the handle portion 29 is provided at a position shifted about 90 degrees around the container main body 22 with respect to the spout portion 28. Then, the user of the teapot 10 can pour a drink (tea) from the spout portion 28 into a cup of tea or the like by lifting the teapot 10 and tilting the teapot 10 by grasping the handle portion 29 by hand. It can be done. In addition to the handle portion 29 fixed to one side portion of the container body portion 22 as described above, a handle or the like that supports the container body portion so as to be suspended may be used, and the handle may be omitted. That is, the handle portion is not limited to the above example, and may be configured to be connected to the container main body portion 22 and to be able to lift and tilt the container main body portion 22.

  The lid portion 12 is configured to be detachably attached to the opening portion 27. More specifically, the lid portion 12 is formed in a shallow dish shape and is configured to be able to close the opening portion 27. Then, by placing the outer peripheral edge of the lid 12 on the opening 27, the opening 27 can be closed by the lid 12. Also, from this state, the lid 12 can be removed from the opening 27 by lifting the lid 12 upward. In addition, a knob portion 13 is projected at a substantially central portion of the outer surface (upper surface) of the lid portion 12, and when the user pinches the knob portion 13 by hand, the lid portion 12 is moved with respect to the opening portion 27. Can be easily attached and detached.

  3 is a perspective view showing the extraction mesh tool 30, FIG. 4 is a cross-sectional view taken along line AA of FIG. 3, FIG. 5 is an exploded view of the extraction mesh tool 30, and FIG. FIG.

  As shown in FIGS. 1 to 6, the extraction net tool 30 includes an extraction net 31 and a bottom 40, and is configured to be detachable from the container body 22 through the opening 27. .

  The extraction net 31 is a member formed in a cylindrical shape having a mesh, and includes a net part 32, an upper frame part 34, and a lower frame part 36.

  The net part 32 has a configuration in which a net material is formed in a cylindrical shape. Here, the net part 32 is formed in a cylindrical shape having the same diameter along the axial direction. Although it is not essential that the net part 32 has a cylindrical shape having the same diameter along the axial direction, the net part 32 can be easily manufactured from a net material spreading in a plane if such a shape is used. There is. In addition, the extraction net may have a polygonal cylindrical shape. As the mesh material, a stainless steel mesh material formed of stainless fine wires, other metal meshes, resin meshes, vegetable meshes, and the like can be used. In addition, when a connection portion is generated when the mesh material is processed into a cylindrical shape, the mesh material may be joined by welding or the like, or only the end portions of the mesh material may be disposed so as to overlap each other.

  The upper frame portion 34 is formed by bending a stainless steel strip or the like into a circular shape and bending it in a double fold shape so as to sandwich the opening on the other side (upper side) of the net portion 32. . In addition to the above configuration, the upper frame portion 34 may be attached to the other edge (upper side) edge opening of the mesh portion 32 by a sewing structure or the like, similarly to the lower frame portion 36 described below.

  The lower frame portion 36 is a member formed by bending a stainless steel strip or the like into a circular shape, and is a member as an annular frame portion attached to one side opening of the mesh portion 32.

  The outer peripheral side portion of the lower frame portion 36 protrudes from the outer periphery of the net portion 32. Therefore, the outer peripheral side portion of the lower frame portion 36 serves as an annular convex portion 36a formed along the circumferential direction.

  For attachment of the lower frame portion 36 to the one side opening of the net portion 32, for example, a sewing structure using holes formed in the lower frame portion 36 and threads such as nylon can be adopted. In this case, in order to make the gap between the mesh portion 32 and the lower frame portion 36 as small as possible, it is preferable to perform the above-described sewing in a state where the upper end portion of the lower frame portion 36 is covered with one side opening of the mesh portion 32. In addition, as in the case of the upper frame portion 34, the lower frame portion 36 is connected to the mesh portion 32 by, for example, inserting an end edge opening on one side (lower side) of the mesh portion 32 with the lower frame portion 36. It may be attached. However, the lower frame portion 36 is not essential.

  The bottom portion 40 is a member that is detachably attached to one side (lower side) opening of the extraction netting tool 30.

  Here, the bottom portion 40 is an integrally molded member formed of resin (soft resin or the like), and includes a bottom main body portion 42 and a peripheral wall portion 44.

  The bottom main body 42 is formed in a plate shape (here, a disc shape) that can close the one-side opening of the extraction netting tool 30.

  The peripheral wall portion 44 is formed in an annular wall shape that rises from the outer periphery of the bottom main body portion 42. The inner diameter of the peripheral wall portion 44 is set to be approximately the same as the outer diameter of the one side opening of the extraction netting tool 30, and is configured to be able to be externally fitted to the outer periphery of the one side opening of the extraction netting tool 30. The protruding dimension (vertical direction dimension) of the peripheral wall portion 44 is set to be larger than the height dimension of the lower frame portion 36, and one side opening of the extraction netting tool 30 so that the peripheral wall portion 44 covers the entire lower frame portion 36. It is preferred that it be attached to the part, but this is not essential.

  An annular recess 45 that fits with the annular protrusion 36 a is formed on the inner peripheral surface of the peripheral wall 44. And the annular convex part 36a fits in the cyclic | annular recessed part 45 in the whole circumferential direction of the one side opening part of the extraction net | network tool 30, Thereby, the attachment state of the bottom part 40 with respect to the one side opening part of the extraction net | network tool 30 is maintained. The The detachment of the bottom 40 can be easily performed using disconnection deformation of at least one of the opening on the one side of the extraction netting tool 30 and the bottom 40.

  In the above example, the annular projection 36a is formed in the opening on one side of the extraction mesh tool 30 and the annular recess 45 is formed in the bottom 40. However, the concavo-convex relationship is reversed, that is, the extraction mesh tool. An annular recess may be formed on the bottom, and an annular protrusion may be formed on the bottom.

  Moreover, although the bottom part 40 demonstrated in the said example by the external fitting with respect to the one side opening part of the extraction net | network tool 30, it is the structure by which a bottom part is internally fitted with respect to the one side opening part of an extraction net | network tool. There may be. An annular convex portion or an annular concave portion may be formed on the inner peripheral side of the one side opening of the extraction netting tool 30, and an annular concave portion or an annular convex portion may be formed on the outer peripheral side of the bottom portion.

  However, it is not essential that the annular convex portion and the annular concave portion are formed.

  As described above, the height dimension of the extraction netting tool 30 is preferably about the distance connecting the bottom 23 and the opening 27. In addition, the outer diameter of the extraction netting tool 30 is preferably about the inner diameter of the opening 27.

  The usage method of the teapot 10 comprised in this way is demonstrated.

  First, the extraction netting tool 30 is disposed in the empty container part 20 through the opening 27. In this state, the substance to be extracted is put into the extraction netting tool 30 through the other side (upper side) opening of the extraction netting tool 30 arranged in the opening 27 above the container part 20. Note that the extraction object may be put into the extraction netting tool 30 in a state before the extraction netting tool 30 is arranged in the container portion 20.

  Thereafter, hot water is poured into the container part 20 through the opening 27 above the container part 20. Then, as shown in FIG. 7, the to-be-extracted object in the container part 20 is immersed in hot water. At this time, since the extraction netting tool 30 is placed on the bottom 23 of the container part 20, even if a small amount of hot water is poured into the container part 20, the extraction object is easily immersed in the hot water. . For this reason, even if it is a small amount of hot water, the drink component etc. can fully be extracted from a to-be-extracted thing.

  After pouring hot water into the container part 20, the lid part 12 is attached, and when an appropriate time has passed for extracting the beverage components, the extraction netting tool 30 is taken out from the container part 20. At this time, hot water (beverage) in which the extracted components are dissolved passes through the extraction netting tool 30, and the extractables remain in the extraction netting tool 30. Moreover, since hot water is filtered using the whole circumference | surroundings of the cylindrical extraction net tool 30, the filtration area can be made comparatively large. Thereby, the hot water in the extraction netting tool 30 can be smoothly left in the container part 20. Further, since the bottom 40 is attached to the one side opening of the extraction net 31 of the extraction net 30, the passage of the extraction object from the bottom side portion of the extraction net 30 is also suppressed.

  And the to-be-extracted object L which sinked to the bottom is stored in the bottom part 40 of the extraction netting tool 30, and especially the powdery to-be-extracted object Ls is easy to store in the bottom, ie, the part enclosed by the surrounding wall part 44. . For this reason, the to-be-extracted substance L (especially powdery to-be-extracted substance Ls) which was sunk in the bottom in the container part 20 is surrounded by the surrounding wall part 44, and it becomes difficult to flow out outside, and the drink remaining in the container part 20 Mixing of the powdery extract Ls and the like is suppressed.

  Then, the user holds the handle portion 29 by hand, lifts the teapot 10, and tilts the teapot 10 so that the spout portion 28 faces downward. Then, the hot water in which the extracted components are dissolved in the container portion 20, that is, the beverage, flows out from the spout portion 28 and is poured into a container such as a hot drink under the spout portion 28. At this time, since the extraction object L is removed together with the extraction netting tool 30, the extraction object L is hardly mixed in the beverage.

  But after extracting a drink from the container part 20, you may take out the extraction netting tool 30 from the container part 20. FIG.

  The extraction net tool 30 taken out from the container unit 20 is subjected to removal and washing of the extraction object L. That is, the extraction netting tool 30 is drawn upward through the opening 27 with the lid 12 removed. Then, as shown in FIG. 8, the bottom 40 is removed from the extraction net 31. At this time, if the bottom 40 is fitted on the extraction net 31, it can be easily removed with the outer circumference of the extraction net 31 and the bottom 40. Then, water is poured on the bottom 40 vigorously mainly, and the extract attached to the bottom 40 is washed away using a brush or the like as necessary. At this time, since the bottom portion 40 is removed from both the container portion 20 and the extraction net 31, water can be poured to any position of the bottom portion 40 and brush cleaning can be performed. Moreover, since the bottom 40 is not formed with a mesh or the like, the extractables L (particularly the powdery extractables Ls) that easily adhere to the bottom 40 can be easily washed away.

  Further, water is poured on the entire extraction net 31, and the extract to be extracted attached to the extraction net 31 is washed away using a brush or the like as necessary. At this time, since both ends of the extraction net 31 are open, it can be easily washed. In particular, since the extraction net 31 is removed from the container portion 20, water can be poured from the outside of the extraction net 31, so that the attached extraction object can be more reliably washed away.

  In addition, about the outer periphery of the container part 20, the cover part 12, etc., it can wash | clean by the method similar to the common teapot 10.

  In addition, the said extraction net | network tool 30 is formed in the container shape which has the opening part 62, as shown in FIGS. 9-11, and can be used also for the container 60 for a drink provision to an individual. In the example shown in FIGS. 9 to 11, an example applied to so-called hot water drinking is shown. That is, the container 60 and the extraction netting tool 30 constitute an extractor that produces an extract. As a container for providing beverages to individuals, Western-style teacups such as tea cups and coffee cups, glass cups, and the like are assumed.

  In this case, the extraction net tool 30 is accommodated in the container 60 through the opening 62, the extraction target L is put into the extraction net tool 30, and hot water or the like is poured into the container 60. You can make a beverage that is. Note that the bottom of the extraction netting tool 30 is not necessarily in contact with the bottom of the container 60.

  Thereafter, the extraction mesh tool 30 can be taken out of the container 60 together with the extracted object L after extraction, and the extraction mesh tool 30 can be washed in the same manner as described above. According to this application example, since there is no need to prepare the teapot 10, there is an advantage that a beverage can be easily made.

  In addition, like the modification shown in FIG. 12, the extraction netting tool 30B may be formed in a shape suitable for a container 60B for providing beverages to individuals.

  In the example shown in FIG. 12, an elongated glass container 60B is assumed, and the extraction netting tool 30B is formed in a shape suitable for the container 60B. That is, the extraction netting tool 30B is formed in an elongated bottomed cylindrical shape corresponding to the internal shape of the container 60B. In order to allow the extraction mesh tool 30 to be easily taken out while hot water is poured into the container 60B, the height dimension of the extraction mesh tool 30B is large enough to reach the opening 62 of the container 60B or more. It is preferable that it is the magnitude | size of.

  In addition, the extraction net | network tool 30 removed from the container part 20 and the containers 60 and 60B may be temporarily mounted on the desk etc. Even in this case, since the peripheral wall portion 44 is provided in the bottom portion 40, the peripheral wall portion 44 suppresses the liquid contained in the extract L from spilling on the desk.

  According to the extraction net tools 30 and 30B and the extractor configured as described above, the bottom 40 is attached to the opening on one side of the extraction net 31, so that the object to be extracted is contained in the container 20 and the containers 60 and 60B. The thing L becomes difficult to leak from the extraction netting tools 30 and 30B. In addition, the extract L, particularly the extract Ls such as fine powdered tea, can be easily stored on the bottom 23, so that the bottom 40 can be removed from the extraction net 31 with the extraction net tools 30 and 30B removed. it can. Then, by washing the bottom portion 40, the extract, in particular, the fine extract Ls that is difficult to be washed away can be easily removed.

  In addition, since the peripheral wall portion 44 is provided in the bottom portion 40, most of the fine extraction object Ls stored near the bottom portion 40 is stored inside the peripheral wall portion 44. And the outflow of the said fine to-be-extracted object Ls by the surrounding wall part 44 is suppressed more reliably.

  Furthermore, since the lower frame part 36 is provided in the one side opening of the net part 32, the shape of the one side opening part of the extraction net 31 can be kept in a more constant shape. Thereby, attachment / detachment with the bottom part 40 externally or internally fitted to the one side opening of the extraction net | network 31 can be continued and performed smoothly.

  In addition, since the bottom portion 40 is externally fitted to one side opening of the extraction net 31, each of the bottom portion 40 and the extraction net 31 is held by holding the outer periphery of the bottom portion 40 and the outer periphery of the extraction net 31 by hand. It can be attached and detached, which is convenient.

  Further, the bottom 40 can be reliably and easily attached to and detached from the extraction net 31 by the fitting structure of the annular protrusion 36 a and the annular recess 45. Moreover, since the annular convex part 36a and the annular concave part 45 are fitted in the whole circumferential direction in the state where the bottom part 40 is attached to the extraction net 31, it is possible to more reliably prevent the extraction object L from leaking between them. Can be suppressed.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
