Patent Document 1

[0005] (1) First aspect In view of the above, the mushroom cultivation bottle cap of the first embodiment of the present application comprises an annular mounting portion that fits onto the outer circumference of the circular wide-mouth portion of the cultivation bottle, and a cylindrical extension portion that extends upward from the mounting portion, wherein the diameter of the extension portion is smaller than the diameter of the wide-mouth portion, and the height of the extension portion is 1 cm or more higher than the upper edge of the wide-mouth portion.

[0006] The cultivation bottle is a wide-mouthed bottle commonly used for mushroom cultivation, with an inner diameter of approximately 50 mm for its circular wide opening. The mushroom cultivation bottle cap of this embodiment is attached by fitting an annular attachment part onto the outer circumference of the wide opening of this cultivation bottle. In this case, since the diameter of the extension part is smaller than the diameter of the wide opening, the cross-sectional area of ​​the extension part becomes smaller than the area of ​​the wide opening, making it possible to compress the stems of clustered mushrooms. In this case, the length of the compressed mushroom stems can be made 1 cm or more. Furthermore, by restricting the mushrooms that tend to grow laterally beyond the inner diameter of the wide opening during the growth process with such a cylindrical extension part, it is possible to compress the stems of multiple clustered mushrooms while simultaneously encouraging them to grow upward.

[0007] The height of the extension is preferably 1 to 12 cm, and more preferably 7 to 10 cm. In other words, the mushroom cultivation bottle cap of this embodiment allows the mushroom stems to grow to such lengths. Stems grown to such lengths are compressed into a cylindrical shape. These cylindrical stems can then be sliced, for example, and used as an ingredient with a fibrous texture similar to scallops, such as in tempura, sautéed dishes, or cutlets.

[0008] The mushroom cultivation bottle cap of this embodiment has a clearly defined cap and stem, making it suitable for cultivating all types of edible mushrooms that grow in clusters. Among such mushrooms, the buna-shimeji is the most suitable. It can also be used for cultivating other mushrooms such as "shimofuri oyster mushroom" (registered trademark) and king oyster mushroom.

[0009] (2) Second aspect The mushroom cultivation bottle cap of the second embodiment of this invention, in addition to the configuration of the first embodiment, has the extension portion divided into multiple members in a direction perpendicular to the height direction. With this configuration, when harvesting mushrooms, the mushrooms can first be removed from the cultivation bottle along with the mushroom cultivation bottle cap, and then the lower members can be removed, followed by the upper members in sequence. This makes it easier to remove the mushrooms from the mushroom cultivation bottle cap.

[0010] In this embodiment of the mushroom cultivation bottle cap, for example, an annular lower end connecting portion is formed on the lower end portion of the upper member among the plurality of members, and an annular upper end connecting portion is formed on the upper end portion of the lower member among the plurality of members, which fits into the inner circumference of the lower end connecting portion. That is, the lower end connecting portion of the upper member can be attached to the upper end connecting portion of the lower member, and then the lower member can be attached to the wide opening of the cultivation bottle.

[0011] In this case, the upper end connecting portion may also be formed on the upper end portion of the upper member, and the mounting portion and the lower end connecting portion may have the same shape, so that the upper member and the lower member have the same shape. In this case, since the mushroom cultivation bottle cap can be constructed from multiple single-shaped members, the manufacturing cost of the members can be reduced.

[0012] Furthermore, the inner circumference of the lower end connecting portion may be formed with female threads, and the outer circumference of the upper end connecting portion may be formed with male threads that screw into the lower end connecting portion. In this case, attaching the upper member to the lower member and removing the upper member from the lower member becomes easier. [Effects of the Invention]

[0013] Since the present invention is configured as described above, it is possible to extend the stalk length of the mushroom during cultivation compared to the mushrooms obtained by normal cultivation.

[Modes for carrying out the invention]

[0015] Embodiments of the present invention will be described below with reference to the drawings. Note that the resin materials mentioned below are merely examples, and other materials may be used as appropriate. Furthermore, the components and parts shown in each figure are merely examples and do not necessarily reflect the size and proportions of the actual product. Note that common reference numerals in each figure refer to the same components or parts, even if not explicitly mentioned in the description of each figure.

[0016] (1) First Embodiment (1-1) Cultivation bottles 50 Figure 1 is a front cross-sectional view of a cultivation bottle 50 to which the mushroom cultivation bottle cap 10 of the first embodiment (see Figures 2A to 2E) is attached. The cultivation bottle 50 is molded by blow molding of polypropylene resin, and as shown in Figure 1, it has an elongated body 51 at its upper end, with a sloping shoulder 53 and a narrower cylindrical neck 52 integrally attached thereto. The upper end of this neck 52 is a wide mouth 54. The inner diameter of the wide mouth 54 is, for example, about 50 mm.

[0017] (1-2) Mushroom cultivation bottle caps 10 Figures 2A to 2E are an upper perspective view (Figure 2A), a front view (Figure 2B), a top view (Figure 2C), a bottom view (Figure 2D), and a cross-sectional view (Figure 2E) of line II-II in Figure 2B of the mushroom cultivation bottle cap 10 according to the first embodiment. The mushroom cultivation bottle cap 10 comprises an annular mounting portion 15 that fits onto the outer circumference of the circular wide-mouth portion 54 of the cultivation bottle 50, and a cylindrical extension portion 11 that extends upward from the mounting portion 15 and has a greater length in the height direction than the inner diameter of the wide-mouth portion 54. The inner diameter of the mounting portion 15 is sized to tightly fit onto the outer circumference of the wide-mouth portion 54. That is, the mounting portion 15 covers and fits onto the edge of the wide-mouth portion 54 and the outer surface near the edge.

[0018] The outer diameter of the extension 11 is smaller than the outer diameter of the mounting part 15. The inner diameter of the extension 11 is smaller than the inner diameter of the wide opening 54 of the cultivation bottle 50. The extension 11 is designed to compress and solidify the stem length of the growing mushrooms appropriately within its internal space, while extending them upward. The height of the internal space is, for example, 1 to 12 cm, more preferably 7 to 10 cm, and this height allows the mushroom stems to grow longer than usual.

[0019] (1-3) Method for cultivating and harvesting mushrooms using mushroom cultivation bottle caps 10 An example of a mushroom cultivation process using the mushroom cultivation bottle cap 10 according to this embodiment is as follows. In the example below, the mushroom cultivated is buna shimeji, but it is not limited to this, and the mushroom cultivation bottle cap 10 according to this embodiment can also be used to cultivate, for example, "shimofuri hiratake" (registered trademark) and eringi.

[0020] (1-3-1) Mycelial culture process The culture medium 60, prepared in the same manner as in conventional mushroom cultivation, is filled into cultivation bottles 50, sterilized, and then allowed to cool before being inoculated with spawn 61 to create the substrate (Figure 3). During the cultivation period, the temperature is maintained at 20-21°C in the culture room to allow the mycelium to grow.

[0021] (1-3-2) Mycelial scraping process After the mycelial culture process described above is completed, mycelial scraping is performed in the mycelial scraping room (Figure 4). The point at which this mycelial scraping is completed is designated as day 0 of growth.

[0022] (1-3-3) Sprouting process At this stage, between 0 and 14 days of growth, the attachment part 15 of the mushroom cultivation bottle cap 10 shown in Figure 2E is fitted onto the wide opening 54 of the cultivation bottle 50 (Figure 5), and the bottle is moved to the sprouting chamber. In this state, the room temperature is maintained at about 15°C, and light is shone from above as needed, and the bottle is left undisturbed for about two weeks to allow the fruiting body primordia 62 to sprout (Figure 6).

[0023] (1-3-4) Growth process After the sprouting process is complete, the cultivation bottles 50 fitted with mushroom cultivation bottle caps 10 are moved to the growth chamber. In this state, the room temperature is maintained at approximately 15°C, and light is shone from above as needed, allowing the fruiting body primordia 62 to grow. (Figure 7)

[0024] (1-3-5) Harvest The growth process allows the fruiting body 63 to grow until the cap 66 protrudes from the upper end of the extension 11 (see Figure 8). In this state, the internal space of the extension 11 is filled with the elongated and compressed stem 65. Once the mushrooms have grown to this stage, the cultivation bottle 50 is removed from the growing chamber. Then, by lifting the mushroom cultivation bottle cap 10, the fruiting body 63 is removed from the culture medium 60 and harvested (Figure 9). When the mushroom cultivation bottle cap 10 is removed, mushrooms with clustered stems 65 that are elongated and compressed to about 2 to 3 times their normal length are obtained, as shown in Figure 10.

[0025] As shown in Figure 11, the upper part including the cap 66 and the lower part including the stem 64 of the mushroom are cut off, while the stem 65 in the middle is cut horizontally into multiple pieces (Figure 11). In this figure, the stem 65 is divided into five pieces 67 with a thickness of approximately 1.5 cm (Figure 12). The cross-section of piece 67 shows that the aggregate of multiple stems 65 is pressed together in a roughly circular shape (Figure 13). Each piece 67 is cooked as an ingredient with a fibrous texture similar to scallops, for example, in tempura, sautéed, or cutlet.

[0026] (2) Second Embodiment (2-1) 50 cultivation bottles The cultivation bottle 50 to which the mushroom cultivation bottle cap 10 of the second embodiment is attached is the same as that of the first embodiment (see Figure 1). (2-1) Mushroom cultivation bottle caps 10 The mushroom cultivation bottle cap 10 of the second embodiment is formed by combining two unit members 20 of the same shape. Figures 14A to 14E are an upper perspective view (Figure 14A), a front view (Figure 14B), a top view (Figure 14C), a bottom view (Figure 14D), and a cross-sectional view of XIV-XIV in Figure 14B (Figure 14E) of one of the multiple (2) unit members 20 that constitute the mushroom cultivation bottle cap 10 of the second embodiment. The unit member 20 has a cylindrical extension portion 11 with annular protrusions at both the upper and lower ends. The annular shape with the upper end protruding is the upper end connecting portion 12, and the annular shape with the lower end protruding is the lower end connecting portion 13. The inner diameter of the lower end connecting portion 13 is such that the outer circumference of the wide mouth portion 54 (see Figure 1) of the cultivation bottle 50 fits snugly, and the outer circumference of the upper end connecting portion 12 of another unit member 20 fits snugly. The outer diameter of the extension 11 is smaller than the outer diameter of the mounting part 15. The inner diameter of this extension 11 is smaller than the inner diameter of the wide opening 54 of the cultivation bottle 50.

[0027] As shown in Figure 15A, the two unit members 20 are fitted together by placing the lower end connecting portion 13 of the upper unit member 21 over the upper end connecting portion 12 of the lower unit member 22, thereby forming the mushroom cultivation bottle cap 10 as shown in the upper perspective view of Figure 15B, the front view of Figure 15C, and the cross-sectional view XV-XV of Figure 15C (Figure 15D). The plan view and bottom view of this mushroom cultivation bottle cap 10 are shown in the same way as in Figures 14C and 14D, respectively. The lower end connecting portion 13 of the lower unit member 22 becomes a mounting portion 15 that fits onto the outer circumference of the wide opening 54 (see Figure 1) of the cultivation bottle 50.

[0028] As shown in Figures 15B to 15E, the mushroom cultivation bottle cap 10 of the second embodiment is divided into a plurality (2) unit members 20 along the direction perpendicular to the height direction. Furthermore, an annular lower end connecting portion 13 is formed on the lower end portion of the upper unit member 21 of the plurality of unit members 20, and an annular upper end connecting portion 12 is formed on the upper end portion of the lower unit member of the plurality of unit members 20, which fits into the inner circumference of the lower end connecting portion 13. Moreover, the upper end connecting portion 12 is also formed on the upper end portion of the upper unit member 21, and the mounting portion 15 and the lower end connecting portion 13 have the same shape, so the upper unit member 21 and the lower unit member 22 have the same shape.

[0029] The outer diameter and inner diameter of the extension portion 11, the height of its internal space, and its significance in the mushroom cultivation bottle cap 10 of the second embodiment are the same as in the first embodiment.

[0030] (2-3) Method for cultivating and harvesting mushrooms using mushroom cultivation bottle caps 10 An example of the mushroom cultivation process using the mushroom cultivation bottle cap 10 according to this embodiment is as follows. The mushrooms cultivated in the following example are the same as those in the first embodiment.

[0031] (2-3-1) Mycelial culture process The mycelial culture process is the same as in the first embodiment (Figure 3).

[0032] (2-3-2) Mold scraping process The mycelial scraping process is the same as in the first embodiment (Figure 4).

[0033] (2-3-3) Sprouting process The sprouting process is the same as in the first embodiment, except that the mounting portion 15 of the mushroom cultivation bottle cap 10 shown in Figure 15D is fitted into the wide-mouth portion 54 of the cultivation bottle 50 (see Figure 1) (see Figure 16) (see Figure 6).

[0034] (2-3-4) Growth process The growth process is the same as in the first embodiment, except that the mushroom cultivation bottle cap 10 shown in Figure 15D is used (see Figure 7).

[0035] (2-3-5) Harvest The growth process allows the fruiting body 63 to grow until the cap 66 protrudes from the upper end of the extension 11 (Figure 17). In this state, the internal space of the extension 11 is filled with the elongated and compressed stem 65. Once the fruiting body has grown to this stage, the cultivation bottle 50 is removed from the growing chamber. Then, by lifting the mushroom cultivation bottle cap 10, the fruiting body 63 is removed from the culture medium 60 and harvested (Figure 18). After removing the lower unit member 22 (Figure 19), the upper unit member 21 is removed to obtain a mushroom similar to that of the first embodiment (see Figure 10).

[0036] In this embodiment, since the mushroom cultivation bottle cap 10 is divided into two unit members 20, it is possible to remove each unit member 20 from the stem 65 which is extended in a roughly cylindrical shape, making removal easy.

[0037] (3) Third Embodiment Figure 20 shows a plan view (A), front view (B), cross-sectional view (C), and bottom view (D) of one of the multiple unit members 20 that make up the mushroom cultivation bottle cap 10 of the third embodiment. The unit member 20 has a shape in which a lower end connecting portion 13 protruding in an annular shape is attached to the lower end of a short cylindrical extension portion 11. The inner diameter of the lower end connecting portion 13 is sized to tightly fit the outer circumference of the wide opening portion 54 (see Figure 1) of the cultivation bottle 50.

[0038] The mushroom cultivation bottle cap 10 shown in Figure 21 is formed by stacking five of the unit members 20 shown in Figure 20. In other words, the mushroom cultivation bottle cap 10 of this embodiment is divided into multiple (five) unit members 20 along the direction perpendicular to the height direction.

[0039] In this embodiment, the mushroom cultivation bottle cap 10 can be attached to the wide-mouth portion 54 (see Figure 1) of the cultivation bottle 50, similar to the first and second embodiments, by using the lower end connecting portion 13 of the lowest section as the mounting portion 15.

[0040] (4) Fourth Embodiment Figure 22 is a front view of the fourth embodiment, showing the state in which the unit members 20 are combined to obtain the mushroom cultivation bottle cap 10. This embodiment differs from the second embodiment described above in that a female thread 13A is formed on the inner circumference of the lower end connecting portion 13 of the upper unit member 21, while a male thread 12A is formed on the outer circumference of the upper end connecting portion 12 of the lower unit member 22. That is, a female thread 13A is formed on the inner circumference of the lower end connecting portion 13, and a male thread 12A that screws into the lower end connecting portion 13 is formed on the outer circumference of the upper end connecting portion 12. The shape of the mounting portion 15 of the lower unit member 22 is the same as the shape of the lower end connecting portion 13 of the unit member 20 in the second embodiment described above (see Figures 14A to 14E).

[0041] As shown in Figure 22, by screwing the female thread 13A of the lower end connecting portion 13 of the upper unit member 21 into the male thread 12A of the upper end connecting portion 12 of the lower unit member 22, a mushroom cultivation bottle cap 10 with the same appearance as the mushroom cultivation bottle cap 10 of the second embodiment (see Figures 15B to 15D) can be obtained. The mushroom cultivation bottle cap 10 of this embodiment can be attached to the wide opening portion 54 of the cultivation bottle 50 (see Figure 1) using the mounting portion 15 of the lower unit member 22, similar to the first and second embodiments.

[0042] (5) Fifth embodiment Figure 23A is a front view of the fifth embodiment, showing how two divided members 16 are combined to obtain a mushroom cultivation bottle cap 10. The divided member 16 is a mushroom cultivation bottle cap 10, as shown in Figures 2A and 2B, divided vertically into two halves. The vertical edges of the divided member 16 have an equal number of alternating protrusions 17 and recesses 18. Opposing protrusions 17 and recesses 18 are formed to be substantially the same shape so that they fit together. In other words, the two divided members 16 are exactly the same shape.

[0043] By fitting the opposing convex portion 17 and concave portion 18 of these two dividing members 16 together, a mushroom cultivation jar cap 10 as shown in Figure 23B is obtained. This mushroom cultivation jar cap 10 can be used in the same way as in the first embodiment. In this embodiment, as shown in Figure 9, the mushroom cultivation jar cap 10 can be split into left and right halves from the state in which the mushrooms have been harvested together with the mushroom cultivation jar cap 10 to remove the mushrooms. [Industrial applicability]

[0044] This invention can be used for cultivating clustering mushrooms such as buna shimeji. [Explanation of symbols]
