[0001] The present invention relates to a two - liquid mixing container that separately stores a first liquid and a second liquid and can easily mix the first liquid and the second liquid during use.

Background Art

[0002] Two - liquid mixing containers are used, for example, in applications where a liquid extract having a flavor is mixed with a beverage stored in a container body to make a final beverage.

[0003] Conventionally, as such a two - liquid mixing container, it includes a container body for storing a first liquid, an inner cylinder provided with a partition wall that opens in a sliding manner at the lower end, a base fixed to the mouth portion, and an intermediate cylinder that fits inside the inner cylinder and partitions a storage chamber for the second liquid together with the inner cylinder, and a cap attached to the base by screw connection. When the cap is rotated in the tightening direction with respect to the base and moved downward, the lid is opened by being pushed by the intermediate cylinder, and the second liquid stored in the storage chamber flows into the inside of the container body and is mixed with the first liquid. Such a configuration is known (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the above - mentioned conventional two - liquid mixing container, when the cap moves downward with respect to the base and the lid is opened, the second liquid flows into the inside of the container body by its own weight from the opening formed by the opening of the lid.

[0006] However, when the second liquid is a liquid extract, there is a need to forcefully spray the second liquid into the container body at a predetermined pressure to mix it with the first liquid, and in this respect, there was room for improvement in conventional two-liquid mixing containers.

[0007] The present invention was developed to solve these problems, and its objective is to provide a two-liquid mixing container that can forcefully spray the second liquid into the container body at a predetermined pressure and mix it with the first liquid. [Means for solving the problem]

[0010] In the two-liquid mixing container of the present invention, it is preferable that a ratchet mechanism is provided between the cylindrical body and the pressurizing cylinder, which allows the rotating operating body, which rotates integrally with the pressurizing cylinder, to rotate in the tightening direction relative to the cylindrical body, and prevents it from rotating in the loosening direction relative to the cylindrical body.

[0011] In the two-liquid mixing container of the present invention, it is preferable that the outer peripheral wall portion has a locking projection that undercuts and engages with a projection provided on the outer peripheral surface of the inner peripheral wall portion.

[0012] In the two-liquid mixing container of the present invention, it is preferable that the outer peripheral wall portion has a locking projection that undercuts and engages with a projection provided on the outer peripheral surface of the fixing portion.

[0013] In the two-liquid mixing container of the present invention, it is preferable that a stopper member is detachably mounted between the peripheral wall portion and the fixed portion in the above configuration. [Effects of the Invention]

Embodiment for Carrying out the Invention

[0016] Hereinafter, with reference to the drawings, the two-liquid mixing container 1 according to an embodiment of the present invention will be illustrated and described in detail.

[0017] In this specification and the claims, the vertical direction means the vertical direction in the state where the two-liquid mixing container 1 is in a upright posture as shown in FIG. 1, the radial direction means the direction along a straight line passing through the axis O of the two-liquid mixing container 1 and perpendicular to the axis O, and the circumferential direction means the direction around the axis O.

[0018] The two-liquid mixing container 1 shown in FIG. 1 has a container body 10 and a cap 20 attached to the mouth portion 11 of the container body 10. The first liquid L1 is stored in the first storage chamber R1 inside the container body 10, and the second liquid L2 to be mixed with the first liquid L1 is stored in the second storage chamber R2 provided in the cap 20. At the time of use, the first liquid L1 and the second liquid L2 can be easily mixed inside the container body 10.

[0019] The first liquid L1 and the second liquid L2 are liquids of different types. In this embodiment, the first liquid L1 stored in the first storage chamber R1 of the container body 10 is a beverage, and the second liquid L2 stored in the second storage chamber R2 of the cap 20 is a liquid extract having a flavor.

[0020] The first liquid L1 and the second liquid L2 are not limited to the above-mentioned beverage and extract. For example, they can be liquids such as chemical liquids and liquid cosmetics that exhibit a predetermined efficacy by mixing two liquids. However, two types of liquids whose efficacy disappears relatively early after mixing can be adopted.

[0021] The container body 10 has a bottle shape with a mouth portion 11 and a bottomed cylindrical body portion 13 that is integrally connected to the lower end of the mouth portion 11 via a shoulder portion 12. The mouth portion 11 has a cylindrical shape centered on the axis O, and a male thread 11a is integrally provided on its outer peripheral surface. The inside of the body portion 13 is a first storage chamber R1 for storing the first liquid L1.

[0022] The container body 10 can be made of a synthetic resin material such as polyethylene terephthalate, low-density polyethylene, or high-density polyethylene formed by blow molding or injection molding. However, it can also be made of other materials such as glass or metal.

[0023] The shape of the container body 10 is not limited to the above shape as long as it has a cylindrical mouth portion 11 and a first storage chamber R1, and the shape can be variously changed.

[0024] As shown in FIG. 2, the cap 20 has a fixing member 20A, a movable member 20B, and a piston body 20C.

[0025] The fixing member 20A has a fixing portion 21, a storage cylinder portion 22, a nozzle portion 23, and a cylindrical body portion 24. In this embodiment, the fixing member 20A has a configuration in which the fixing portion 21, the storage cylinder portion 22, the nozzle portion 23, and the cylindrical body portion 24 are integrally formed by injection molding of a synthetic resin material.

[0026] The fixing portion 21 has a cylindrical shape with a diameter larger than that of the mouth portion 11 and coaxial with the mouth portion 11. The fixing portion 21 is disposed outside the mouth portion 11 and is detachably fixed to the mouth portion 11 by screwing a female thread 21a provided on its inner peripheral surface with the male thread 11a.

[0027] The storage cylinder portion 22 has a cylindrical shape with a diameter smaller than that of the mouth portion 11 and coaxial with the mouth portion 11. The storage cylinder portion 22 is connected to the fixing portion 21 via a flange-like portion 21b and is disposed inside the mouth portion 11. A second storage chamber R2 for storing the second liquid L2 is provided inside the storage cylinder portion 22.

[0028] The nozzle portion 23 is equipped with a spray hole 23a that opens toward the inside of the container body 10 and is provided in connection with the lower end of the storage cylinder portion 22. In this embodiment, the nozzle portion 23 is a substantially cylindrical shape with a bottom and a smaller diameter than the storage cylinder portion 22, and is provided integrally with the lower end of the storage cylinder portion 22 via a stepped portion 23b. The bottom portion of the nozzle portion 23 is a tapered portion 23c, and a spray hole 23a is provided in the center of the lower end of the tapered portion 23c along the axis O. The inner diameter of the spray hole 23a is sufficiently smaller than the inner diameter of the storage cylinder portion 22. The nozzle portion 23 is equipped with a closure cylinder portion 23d which is larger in diameter than the tapered portion 23c and is integrally connected to the upper side of the tapered portion 23c, and a tapered closure / opening cylinder portion 23e which is larger in diameter than the closure cylinder portion 23d and is integrally connected to the upper side of the closure cylinder portion 23d.

[0029] The cylindrical body portion 24 has a larger diameter than the storage cylinder portion 22 and is cylindrical in shape and coaxial with the storage cylinder portion 22. The cylindrical body portion 24 is attached to the upper end of the storage cylinder portion 22 via a flange-like portion 21b. A male screw 24a is integrally provided on the outer circumferential surface of the cylindrical body portion 24.

[0030] The movable member 20B has a rotating operating body 25 and a pressurizing cylinder portion 26.

[0031] The rotating operating body 25 is a top-cylindrical shape having a circumferential wall portion 25a and a top wall portion 25b, and is attached to the outside of the cylindrical body portion 24 by screw connection at the circumferential wall portion 25a. That is, the circumferential wall portion 25a is a cylindrical shape with a larger diameter than the cylindrical body portion 24 and is arranged coaxially on the outside of the cylindrical body portion 24. An internal thread 25c is provided on the inner circumferential surface of the circumferential wall portion 25a, and the rotating operating body 25 is attached to the outside of the cylindrical body portion 24 by screw connection of the internal thread 25c to the external thread 24a of the cylindrical body portion 24. The rotating operating body 25, which is attached to the cylindrical body portion 24 by screw connection, can move relative to the cylindrical body portion 24 downward by rotating in the tightening direction relative to the cylindrical body portion 24.

[0032] In the initial state, the rotating operating body 25 is positioned at a predetermined vertical position relative to the cylindrical body 24 such that there is a predetermined distance between its lower end and the upper end or flange-shaped portion 21b of the fixing portion 21.

[0033] In this embodiment, the rotating operating body 25 has a double structure, comprising an inner circumferential wall portion 25A that is screw-connected to the outside of the cylindrical portion 24, and an outer circumferential wall portion 25B that is mounted on the outside of the inner circumferential wall portion 25A in a way that prevents rotation and is connected to the top wall portion 25b. As shown in Figure 3, the outer circumferential surface of the inner circumferential wall portion 25A is provided with irregularities 25d that extend vertically along its entire circumference, and the inner circumferential surface of the outer circumferential wall portion 25B is provided with irregularities 25e that extend vertically along its entire circumference. These irregularities 25d and 25e engage with each other, preventing the inner circumferential wall portion 25A and the outer circumferential wall portion 25B from rotating relative to each other in the circumferential direction around the axis O.

[0034] As shown in Figure 2, a projection 25f is integrally provided on the outer circumferential surface of the inner circumferential wall portion 25A, and a locking projection 25g is integrally provided on the inner circumferential surface of the outer circumferential wall portion 25B. The inner circumferential wall portion 25A is mounted to the outer circumferential wall portion 25B in a state where it is held in place and prevents it from coming loose, as its upper end abuts against the lower surface of the top wall portion 25b which is integrally connected to the outer circumferential wall portion 25B, and the locking projection 25g engages with the projection 25f in an undercut manner.

[0035] The pressurized cylinder portion 26 is cylindrical in shape with a smaller diameter than the storage cylinder portion 22 and the cylindrical body portion 24. The pressurized cylinder portion 26 protrudes downward from the top wall portion 25b and is provided coaxially inside the cylindrical body portion 24. In this embodiment, the pressurized cylinder portion 26 is integrally connected to the upper end of the inner peripheral wall portion 25A via a flange portion 25h. The upper end of the pressurized cylinder portion 26 is closed by the top wall portion 25b, and the inside is a pressurized chamber R3. In order to seal the upper end of the pressurized cylinder portion 26, a cylindrical seal portion 25i that fits liquid-tight and airtightly to the inner peripheral surface of the pressurized cylinder portion 26 may be integrally provided on the lower surface of the top wall portion 25b.

[0036] The piston body 20C includes a first sliding portion 30 that contacts the inner circumferential surface of the storage cylinder portion 22 over its entire circumference, a second sliding portion 31 that contacts the inner circumferential surface of the pressurizing cylinder portion 26 over its entire circumference, a closing plug portion 32 that closes the injection hole 23a, and a communication hole 33 that connects the second storage chamber R2 and the pressurizing chamber R3. The piston body 20C can be made of an elastic material such as synthetic rubber.

[0037] More specifically, as shown in Figures 2 and 3, the piston body 20C has a cylindrical main body tubular portion 34 with a smaller diameter than the pressurizing cylinder portion 26, and a lip-shaped first sliding portion 30 is integrally provided on the outer circumferential surface of the lower end of the main body tubular portion 34. The upper end of the main body tubular portion 34 is slightly enlarged upwards, and this enlarged portion constitutes the second sliding portion 31. The closure plug portion 32 is cylindrical with a smaller diameter than the main body tubular portion 34, and its upper end portion is coaxially arranged inside the main body tubular portion 34 and integrally connected to the inner circumferential surface of the main body tubular portion 34 by a plurality (four) of connecting walls 35 arranged at equal intervals in the circumferential direction. The lower end portion of the closure plug portion 32 protrudes downward from the lower end of the main body tubular portion 34 and closes the injection hole 23a by fitting into the inner circumferential surface of the closure cylinder portion 23d of the nozzle portion 23. The communication holes 33 are partitioned and formed between adjacent connecting walls 35 on the inside of the main body cylindrical portion 34. In this embodiment, the piston body 20C is provided with four communication holes 33, but the number can be changed in various ways.

[0038] In its initial state, the piston body 20C is positioned such that the closure plug portion 32 is fitted to the inner circumferential surface of the closure cylinder portion 23d of the nozzle portion 23, thereby closing the injection hole 23a, i.e., blocking communication between the second storage chamber R2 and the injection hole 23a. Furthermore, when the inside of the second storage chamber R2 is pressurized, the piston body 20C is pushed upward by the pressure, causing the first sliding portion 30 to slide along the inner circumferential surface of the storage cylinder portion 22 and the second sliding portion 31 to slide along the inner circumferential surface of the pressurizing cylinder portion 26, thereby moving upward relative to the fixing member 20A. When the piston body 20C has moved upward by a predetermined distance relative to the fixing member 20A, the closure plug portion 32 detaches from the inner circumferential surface of the closure cylinder portion 23d of the nozzle portion 23 and is positioned inside the closure / opening cylinder portion 23e. As a result, the second storage chamber R2 and the injection hole 23a are connected through the gap between the blocking plug portion 32 and the blocking cylindrical portion 23d, and the injection hole 23a is opened.

[0039] The two-liquid mixing container 1 of this embodiment can also be configured to include a ratchet mechanism 40 between the cylindrical body portion 24 and the pressurizing cylinder portion 26, which allows the rotating operating body 25, which rotates integrally with the pressurizing cylinder portion 26, to rotate in the tightening direction relative to the cylindrical body portion 24, and prevents it from rotating in the loosening direction relative to the cylindrical body portion 24.

[0040] More specifically, as shown in Figures 2 and 3, the ratchet mechanism 40 comprises a plurality of locking protrusions 41 integrally provided on the inner circumferential surface of the cylindrical portion 24 at equal intervals in the circumferential direction, and a plurality of locking protrusions 42 integrally provided on the outer circumferential surface of the pressurizing cylindrical portion 26, which is connected to the rotating operating body 25 and rotates together with the rotating operating body 25, at equal intervals in the circumferential direction. The locking protrusions 41 and 42 are wedge-shaped and oriented in opposite directions in the circumferential direction. When the rotating operating body 25 rotates relative to the cylindrical portion 24 in the tightening direction, the ratchet mechanism 40 operates so that the locking protrusions 41 overcome the locking protrusions 42 to allow the rotation, and when the rotating operating body 25 rotates relative to the cylindrical portion 24 in the loosening direction, the locking protrusions 41 engage with the locking protrusions 42 to prevent the rotation.

[0041] As shown in Figure 2, the two-liquid mixing container 1 of this embodiment can also be configured such that a stopper member 50 is detachably mounted between the peripheral wall portion 25a of the rotating operating body 25 and the fixed portion 21. The stopper member 50 has a C-shape centered on axis O and is positioned without gap between the peripheral wall portion 25a and the fixed portion 21 to restrict the relative downward movement of the rotating operating body 25 with respect to the fixed portion 21, i.e., the fixed member 20A. The stopper member 50 has a handle 51 and can be removed from the cap 20 by pulling the handle 51 radially outward.

[0042] Next, a method for using the two-liquid mixing container 1 having the above configuration will be described.

[0043] As shown in Figures 1 and 2, the first liquid L1 is filled into the first storage chamber R1 of the container body 10, and the second liquid L2 is filled into the second storage chamber R2 of the cap 20.

[0044] In this embodiment, the two-liquid mixing container 1 has a rotating operating body 25 which has an inner peripheral wall portion 25A that is screw-connected to the outside of the cylindrical portion 24 and an outer peripheral wall portion 25B that is mounted on the outside of the inner peripheral wall portion 25A in a way that prevents rotation and is connected to the top wall portion 25b, and a pressurized cylindrical portion 26 is integrally connected to the upper end of the inner peripheral wall portion 25A via a flange portion 25h. Therefore, before attaching the portion of the rotating operating body 25 consisting of the outer peripheral wall portion 25B and the top wall portion 25b to the inner peripheral wall portion 25A, the second liquid L2 can be easily filled into the second storage chamber R2 by filling the second storage chamber R2 with the second liquid L2, and then attaching the portion consisting of the outer peripheral wall portion 25B and the top wall portion 25b to the inner peripheral wall portion 25A.

[0045] Furthermore, according to the two-liquid mixing container 1 of this embodiment, the outer peripheral wall portion 25B is configured to have a locking projection 25g that undercuts and engages with a projection 25f provided on the outer peripheral surface of the inner peripheral wall portion 25A. Therefore, after filling the second storage chamber R2 with the second liquid L2, the portion consisting of the outer peripheral wall portion 25B and the top wall portion 25b can be easily attached to the inner peripheral wall portion 25A.

[0046] Once the second liquid L2 is filled into the second storage chamber R2, the cap 20 is then attached to the mouth 11 of the container body 10. When the cap 20 is attached to the mouth 11 of the container body 10, the two-liquid mixing container 1 is completed. At this time, the rotating operating body 25 of the cap 20 is in the initial position shown in Figure 2 relative to the cylindrical body 24 or the fixing member 20A. In this state, since the first liquid L1 and the second liquid L2 are stored separately in the two-liquid mixing container 1, deterioration of the flavor or properties of the first liquid L1 and the second liquid L2 can be suppressed.

[0047] Furthermore, during distribution, the mouth 11 of the container body 10 may be closed with a lid separate from the cap 20, and the cap 20, which is filled with the second liquid L2 in the second storage chamber R2, may be kept separate from the container body 10. At the time of use (when mixing the first liquid L1 with the second liquid L2), the cap 20 may be attached to the mouth 11 of the container body 10.

[0048] Next, the handle 51 of the stopper member 50 is pulled radially outward to remove the stopper member 50 from the cap 20. As shown in Figure 4, when the stopper member 50 is removed from the cap 20, a gap is created between the lower end of the inner peripheral wall portion 25A that constitutes the peripheral wall portion 25a of the rotating operating body 25 and the flange-shaped portion 21b that constitutes the upper end of the fixing portion 21, and the rotating operating body 25 is made to move downward relative to the fixing portion 21, i.e., the fixing member 20A, so as to narrow the gap.

[0049] Next, from the state shown in Figure 4, the rotating operating body 25 is rotated in the tightening direction relative to the cylindrical body 24, moving the rotating operating body 25 downward relative to the cylindrical body 24. As a result, the movable member 20B moves downward relative to the fixed member 20A, as shown in Figure 5. When the movable member 20B moves downward by a predetermined distance relative to the fixed member 20A, the lower end of the inner peripheral wall portion 25A of the rotating operating body 25 comes into contact with the flange-shaped portion 21b that constitutes the upper end of the fixed portion 21, and the downward movement of the movable member 20B relative to the fixed member 20A is restricted.

[0050] Here, when the movable member 20B moves downward relative to the fixed member 20A, the gap between the nozzle portion 23 and the top wall portion 25b is narrowed, and the air inside the pressurizing chamber R3 is pressurized. When the air inside the pressurizing chamber R3 is pressurized, the pressurized air flows into the second storage chamber R2 through the communication hole 33, acting to push the first sliding portion 30 of the piston body 20C upward. As a result, the piston body 20C moves upward relative to the fixed member 20A or the storage cylinder portion 22, the closing plug portion 32 detaches from the closing cylinder portion 23d and moves to the inside of the closing / opening cylinder portion 23e, and the second storage chamber R2 communicates with the injection hole 23a. Note that when the piston body 20C moves upward relative to the fixed member 20A or the storage cylinder portion 22 by a predetermined distance, the first sliding portion 30 comes into contact with the lower end of the pressurizing cylinder portion 26, and further movement is restricted.

[0051] When the closure plug 32 detaches from the closure cylinder 23d and the second storage chamber R2 communicates with the injection hole 23a, the second liquid L2 stored in the second storage chamber R2 is injected from the injection hole 23a of the nozzle 23 into the inside of the container body 10, i.e., into the first storage chamber R1, and the first liquid L1 and the second liquid L2 are mixed inside the first storage chamber R1. At this time, the air inside the second storage chamber R2 is pressurized, so the second liquid L2 is forcefully injected from the injection hole 23a into the inside of the container body 10 while pressurized by the air. Therefore, the second liquid L2 is efficiently mixed with the first liquid L1 so that its properties or effects are appropriately produced.

[0052] Thus, with the two-liquid mixing container 1 of this embodiment, the second liquid L2 can be forcefully injected from the injection hole 23a into the inside of the container body 10 and mixed with the first liquid L1 by simply rotating the rotating operating body 25 relative to the cylindrical body 24.

[0053] Furthermore, with the two-liquid mixing container 1 of this embodiment, when the pressurizing chamber R3 is pressurized to a predetermined pressure by rotating the rotating operating body 25 relative to the cylindrical body 24, the closure plug 32 moves upward and the spray hole 23a opens. Therefore, the second liquid L2 can always be sprayed into the inside of the container body 10 from the spray hole 23a at the desired pressure, regardless of how well the user rotates the rotating operating body 25.

[0054] Furthermore, in the two-liquid mixing container 1 of this embodiment, a ratchet mechanism 40 is provided between the cylindrical portion 24 and the pressurizing cylindrical portion 26, which operates to allow the rotating operating body 25 to rotate in the tightening direction relative to the cylindrical portion 24 and to prevent the rotating operating body 25 from rotating in the loosening direction relative to the cylindrical portion 24. Therefore, when operating the rotating operating body 25 in the tightening direction relative to the cylindrical portion 24 in order to mix the second liquid L2 with the first liquid L1, it is possible to prevent the rotating operating body 25 from rotating in the loosening direction relative to the cylindrical portion 24, thereby improving the operability of the rotating operating body 25.

[0055] Furthermore, in this embodiment, the two-component mixing container 1 has a structure in which the fixing part 21, the storage cylinder part 22, the nozzle part 23, and the cylindrical body part 24 are integrally formed. This makes it possible to easily mold the fixing part 21, the storage cylinder part 22, the nozzle part 23, and the cylindrical body part 24 by injection molding of synthetic resin material, thereby reducing the cost of this two-component mixing container 1.

[0056] Figure 6 is an enlarged cross-sectional view of the cap 20 portion of the modified two-liquid mixing container 1.

[0057] In the two-liquid mixing container 1 shown in Figure 2, a locking projection 25g provided on the outer peripheral wall portion 25B of the rotating operating body 25 is undercut-engaged with a projection 25f provided on the outer peripheral surface of the inner peripheral wall portion 25A, thereby holding the portion of the rotating operating body 25 consisting of the outer peripheral wall portion 25B and the top wall portion 25b to the inner peripheral wall portion 25A. However, as shown in Figure 6 as a modified example, the outer peripheral wall portion 25B may be configured to slightly expand in diameter at the lower end of the inner peripheral wall portion 25A and then extend to the outside of the fixing portion 21. A locking projection 25g provided on the lower inner peripheral surface of the outer peripheral wall portion 25B is undercut-engaged with a projection 21c provided on the outer peripheral surface of the fixing portion 21, thereby holding the portion of the rotating operating body 25 consisting of the outer peripheral wall portion 25B and the top wall portion 25b to the fixing portion 21. In this case, the stopper member 50 is not installed between the peripheral wall portion 25a and the fixing portion 21.

[0058] With this modified configuration, the gap between the fixing part 21 and the inner peripheral wall 25A of the rotating operating body 25, or the outer peripheral surface of the cylindrical part 24 on which the male thread 24a is provided, is covered by the outer peripheral wall 25B, making it invisible from the outside and thus improving the aesthetic appearance of the cap 20. In addition, since the gap between the fixing part 21 and the inner peripheral wall 25A of the rotating operating body 25 is covered by the outer peripheral wall 25B, it is possible to prevent the operator's hand or foreign objects from getting caught in the gap between the fixing part 21 and the inner peripheral wall 25A of the rotating operating body 25 when the rotating operating body 25 is rotated in the tightening direction.

[0059] The present invention is not limited to the embodiments described above, and it goes without saying that various modifications are possible without departing from the spirit of the invention.

[0060] For example, in the above embodiment, the rotating operating body 25 has an inner peripheral wall portion 25A that is screw-connected to the outside of the cylindrical portion 24, and an outer peripheral wall portion 25B that is mounted on the outside of the inner peripheral wall portion 25A to prevent rotation and is connected to the top wall portion 25b, and the pressurizing cylindrical portion 26 is integrally connected to the upper end of the inner peripheral wall portion 25A via a flange portion 25h, but it is not limited to this configuration, and other configurations are also possible as long as it is a top-cylindrical shape having a peripheral wall portion 25a and a top wall portion 25b, and the peripheral wall portion 25a is screw-connected to the outside of the cylindrical portion 24.

[0061] Furthermore, although a ratchet mechanism 40 is provided between the cylindrical body portion 24 and the pressurized cylindrical portion 26 in the above embodiment, a configuration without a ratchet mechanism 40 is also possible.

[0062] Furthermore, in the above embodiment, the fixing part 21, the storage cylinder part 22, the nozzle part 23, and the cylindrical body part 24 are formed as a single unit, but they can also be assembled as an assembly.

[0063] Furthermore, in the above embodiment, a stopper member 50 is detachably mounted between the peripheral wall portion 25a and the fixing portion 21, but a configuration without a stopper member 50 is also possible. [Explanation of Symbols]
