A medicinal liquid dispenser like the one in Patent Document 1 cannot be installed if there is no water supply tray for hand washing. Even if there is a water supply tray, the medicinal liquid dispenser cannot be installed if, for example, decorative items are placed in the water supply tray. On the other hand, when a dispenser like the ones in Patent Documents 2 and 3 is used, the amount of medicinal liquid that can be applied to the inner surface of the toilet bowl with one stamp is limited, and there is also a risk that the medicinal liquid on the inner surface of the toilet bowl will be peeled off by flushing, making it impossible to dispense the medicinal liquid stably.

The present invention aims to provide a chemical liquid supply device that is easy to secure an installation location for and can stably supply chemical liquid.

The chemical supply device of the present invention is a chemical supply device that can be attached to a water tank of a toilet bowl, which has a tank body with an opening at the top and a lid that covers the opening of the tank body. It comprises a chemical container that contains the chemical, a support that supports the chemical container, a flexible tube that supplies the chemical from the chemical container to the water tank, and a mounting member that supports the tube and is configured to be attachable to the edge of the opening of the tank body, and the support can be selectively attached to the mounting member at either a first position that is close to the water tank, or a second position that is farther from the water tank than the first position.

In the above-mentioned drug solution supply device, the mounting member has a receiving portion that is attached to the support, and the support can have a first side surface, a second side surface opposite the first side surface, a storage space formed between the first side surface and the second side surface in which the receiving portion of the mounting member is stored, and a positioning portion provided in the storage space for positioning a portion of the mounting member on the first side surface side.

In the above-mentioned drug solution supply device, the positioning portion can form the storage space using a fixed plate, and the receiving portion of the mounting member can be configured to be fixed between the fixed plate and the first side surface.

In the above-mentioned chemical liquid supply device, the mounting member comprises an abutment portion having an abutment surface that can abut against the outer surface of the tank body, and a fixing portion that, in the initial state, extends downward from the abutment portion, straddling the edge of the tank body, and along the inner surface of the tank body; the receiving portion, the abutment portion, and the fixing portion can be integrally formed from a flexible material.

In the above-mentioned medicinal liquid supply device, the receiving portion has a recess for receiving the medicinal liquid discharged from the medicinal liquid container, and the tube can be connected to the recess.

This invention has an attachment member that can be attached to the edge of the opening of the tank body, allowing the drug supply device to be attached to a water storage tank that does not have a water supply tray. Furthermore, the attachment member supports a flexible tube that guides the drug solution from the drug solution container to the water storage tank, allowing the drug solution from the drug solution container to be stably supplied to the water storage tank via this tube.

The following describes a chemical liquid supply device according to one embodiment of the present invention, with reference to the drawings. Figure 1 is a perspective view of the chemical liquid supply device according to this embodiment, Figure 2 is an exploded side view of the chemical liquid supply device of Figure 1, and Figure 3 is a cross-sectional view of the water storage tank.

As shown in Figures 1 and 2, this chemical liquid supply device is a device that supplies chemical liquid to the toilet's water tank 1, and is equipped with a chemical liquid container 2 in which the chemical liquid is stored, a chemical liquid guide member 3 for discharging the chemical liquid from the chemical liquid container 2, a support member 4 that supports the chemical liquid container 2 and receives the chemical liquid, and an attachment member 5 for attaching the support member 4 to the toilet's water tank 1.

As shown in Figure 3, the target water storage tank 1 comprises a tank body 11 that stores flushing water and a lid 12 that closes the top opening of the tank body 11. The tank body 11 has a first edge 121 extending downward on the outer periphery of the lid 12, and a second edge 122 that is spaced apart inside the first edge 121. The edge 111 of the top opening of the tank body 11 fits between the first edge 121 and the second edge 122 of the lid 12. Therefore, the lid 12 is installed so that it protrudes slightly outward from the outer periphery of the tank body 11. The above-mentioned mounting member 5 is attached so that it is sandwiched between the tank body 11 and the lid 12. Each component of the chemical solution supply device will be described in detail below.

<1. Chemical solution container>
Fig. 4 is a perspective view of a liquid medicine container. As shown in Fig. 4, liquid medicine container 2 has a transparent, dome-shaped container body 21 with a flat bottom, and liquid medicine is stored in container body 21. An outlet 211 is formed in the bottom surface of container body 21, and a cap 22 is attached to outlet 211 before use. Cap 22 is composed of an annular main body 221 and a thin film 222 that closes the central hole. When using, thin film 222 is broken to discharge the liquid medicine.

The chemical solution contains one or more elements selected from the group including cleaning agents, disinfectants, deodorizers, and fragrances, and may also contain coloring agents. The chemical solution is mixed with flush water stored in the water storage tank, providing the benefits of the ingredients contained in the chemical solution to the toilet bowl or toilet room. For example, if the chemical solution contains a cleaning agent and a disinfectant, it can clean and disinfect the toilet bowl, and if it contains a deodorizer and a fragrance, it can eliminate unpleasant odors and fill the toilet room with a pleasant fragrance.

<2. Chemical Solution Guide Member>
FIG. 5 is a perspective view of the drug solution guide member. The drug solution guide member 3 guides the drug solution discharged from the drug solution container 2 to the support 4. As shown in FIG. 5, the drug solution guide member 3 has a rectangular upper surface 31 and side surfaces 32 extending downward from the periphery thereof. An annular recess 311 is formed in the center of the upper surface 31, and the main body 221 of the cap 22 of the drug solution container 2 fits into this recess 311. A cylindrical communication tube 33 with a sharp, obliquely notched tip is provided inside the recess 311. The communication tube 33 is designed to pierce the thin film portion 222 of the cap 22 of the drug solution container 2. This allows the drug solution from the drug solution container 2 to flow through the communication tube 33 to the receiving portion 42 of the support 4, which will be described next. A protrusion 34 is formed at an opposing location on the side surface 32.

<3. Support>
Next, the support body 4 will be described. Fig. 6 is a perspective view of the support body viewed from above, and Fig. 7 is a perspective view of the support body viewed from below. As shown in Figs. 6 and 7, the support body 4 has a housing 41 that is elliptical in plan view. The internal space surrounded by the housing 41 is provided with a receiving portion 42 to which the drug solution guide member 3 is attached, a pair of support plates 43 that are disposed below the receiving portion 42 and support the receiving portion 42, and a fixing plate 44 for fixing the mounting member 5.

The housing 41 has a pair of long walls 411 extending in the longitudinal direction and a pair of curved short walls 412 extending in the lateral direction, and is configured to support the drug solution container 2 at the upper ends of these. The housing 41 also has multiple openings 413, through which the internal space of the housing 41 communicates with the outside. Note that the openings 413 may be omitted in some drawings.

The pair of support plates 43 are arranged at a predetermined distance from each other in the internal space of the housing 41, extending in the short direction. Both ends of each support plate 43 are connected to the inner wall surface of the housing 41. The receiving portion 51 of the mounting member 5, which will be described later, is arranged between these support plates 43.

The fixed plate 44 is connected to each support plate 43 on both sides and extends longitudinally between these support plates 43. The fixed plate 44 is positioned closer to one of the long wall portions (hereinafter referred to as the first long wall portion 411a and the other long wall portion as the second long wall portion 411b) than the center of the internal space in the short direction. The receiving portion 51 of the mounting member 5 (described below) is fitted between the second long wall portion 411b and the fixed plate 44. More specifically, the distance between the second long wall portion 411b and the fixed plate 44 is slightly shorter than the short-side length of the receiving portion 51. Therefore, the flexible receiving portion 51 is press-fit between the second long wall portion 411b and the fixed plate 44.

The upper end of each support plate 43 is provided with an engagement portion 45 that elastically deforms and engages with the protrusions 34 on both sides of the chemical solution guide member 3, and a receiving portion 42 that receives the chemical solution is positioned between these engagement portions 45. The receiving portion 42 is formed in a rectangular cup shape in a plan view, with a through-hole 421 formed in the center of the bottom surface. The outer edge of the receiving portion 42 fits inside the side portion 32 of the chemical solution guide member 3. A guide plate 46 extends downward from the bottom surface of the receiving portion 42, allowing the chemical solution that passes through the through-hole 421 to flow downward along the guide plate 46. The guide plate 46 is positioned near the center of the lateral direction of the housing 41 and faces the second long wall portion 411b.

<4. Mounting parts>
Fig. 8 is a side view of the mounting member, Fig. 9 is a perspective view of the mounting member seen from above, and Fig. 10 is a perspective view of the mounting member seen from behind. As shown in Figs. 8 to 10, the mounting member 5 includes a receiving portion 51 attached to the support body 4, a contact portion 52 connected to the lower end surface of the receiving portion 51, a fixing portion 53 extending from the contact portion 52 so as to climb over the edge 111 of the tank body 11, and a folded portion 54 extending from the end of the fixing portion 53 toward the contact portion 52, all of which are integrally formed from a flexible material. A known flexible tube 6 is also attached to the mounting member 5.

The receiver 51 is formed in the shape of an octagonal block in plan view, with a rectangular recess 511 formed in the center of its top surface. The bottom of this recess 511 is shaped like a mortar, with a discharge hole 512 formed at the bottom. A rod-shaped member 513 with a through-hole communicating with the discharge hole 512 is attached to the part of the underside of the receiver 51 where the recess 511 is formed. This rod-shaped member 513 is inserted into the upper end of the tube 6, allowing the medicinal liquid that accumulates in the recess 511 to flow into the tube 6 via the discharge hole 512 and the through-hole.

The abutment portion 52 has a front plate 55 extending downward from the receiving portion 51 and a pair of side plates 56 connected to either side of the front plate 55, with the front plate 55 being supported by the pair of side plates 56. The front plate 55 has a first extending surface 551 extending downward from the outer peripheral surface of the receiving portion 51 facing the water tank 1, a curved surface 552 curving downwardly from the lower end of the first extending surface 551 so as to be convex, a second extending surface 553 extending diagonally upward from the curved surface 552, and an abutment surface 554 extending downward from the end of the second extending surface 553. Furthermore, the edge of each side plate 56 facing the water tank 1 is formed to conform to the first extending surface 551, the curved surface 552, the second extending surface 553, and the abutment surface 554. On the other hand, the edge of each side panel 56 opposite the water tank 1 extends obliquely in a straight line from the lower end of the receiving portion 51 to the lower end of the abutting surface 554 .

In the front panel 55, a through-hole 555 is formed in the curved surface 552, and a first groove 556 is formed in the second extending surface 553, extending toward the water tank 1 so as to be continuous with the through-hole 555. As described above, the tube 6 inserted into the rod-shaped member 513 is pulled out toward the water tank 1 through the through-hole 555 and is positioned so as to follow the first groove 556 in the second extending surface 553. The first groove 556 has an arc-shaped cross section, and is formed so as to fill at least 30%, preferably at least 50%, of the cross-sectional area of the tube 6.

A plate-shaped guide member 557 is disposed on the back surface of the first extending surface 551 of the front panel 55. This guide member 557 extends upward from the upper edge of the through-hole 555 and is disposed with a gap between it and the rod-shaped member 513. The edge of the guide member 557 extending from the rod-shaped member 513 to the through-hole 555 is formed in an arc shape. Therefore, the tube 6 inserted into the rod-shaped member 513 is disposed along the edge of the guide member 557 and is guided toward the through-hole 555.

Next, the fixing portion 53 will be described. In its initial state, the fixing portion 53 is formed in a band shape having a curved portion 531 extending convexly upward from the upper end of the second extending surface 553 described above, and an extending portion 532 extending downward from the tip of the curved portion 531. The fixing portion 53 is formed with a second groove 533 that is continuous with the first groove 556 formed in the second extending surface 553. The second groove 533 has a cross-sectional shape similar to that of the first groove 556 and extends across the curved portion 531 and the extending portion 532. In addition, the extending portion 532 is formed with a retaining portion 534 that covers the second groove 533, and the tube 6 fitted into the second groove 533 is covered by the retaining portion 534 to prevent it from coming loose. The tube 6 is long enough to extend downward from the lower end of the extending portion 532.

A strip-shaped folded portion 54 is connected to the lower end of the extending portion 532, extending diagonally upward toward the abutment surface 554. Because the folded portion 54 is elastically deformable, it moves closer to the extending portion 532 when a force is applied. In other words, when the folded portion 54 is pressed, the angle between the folded portion 54 and the extending portion 532 becomes smaller.

The mounting member 5 configured as described above is integrally formed from a flexible material. The material from which the mounting member 5 is made is not particularly limited, but it can be made from materials such as urethane rubber, styrene-butadiene rubber, silicone rubber, and fluororubber. Furthermore, the hardness (International Rubber Hardness) of the mounting member 5 is preferably 60 to 100 IRHD, and more preferably 85 to 95 IRHD. International rubber hardness can be measured, for example, using the test specified in JIS K 6253-2 (ISO 480).

5. Method of assembling and using the chemical solution supply device
Next, we will explain how to assemble and use the chemical solution supply device using the components configured as described above. First, attach the chemical solution guide member 3 to the support body 4. That is, attach the chemical solution guide member 3 so that it covers the receiving portion 42 of the support body 4. At this time, the protrusion 34 of the chemical solution guide member 3 engages with the engagement portion 45 of the support body 4, thereby fixing the chemical solution guide member 3 to the support body 4.

Next, the mounting member 5 is attached to the support body 4. At this time, the method of attaching the mounting member 5 differs depending on the position of the lid body 12 of the water storage tank 1. For example, if the lid body 12 protrudes laterally from the tank body 11 as shown in Figure 3, it is necessary to ensure that the support body 4 does not interfere with the lid body 12. Therefore, the receiving portion 51 of the mounting member 5 is fitted into the support body 4 so that the surface of the receiving portion 51 on the front panel 55 side of the mounting member 5 contacts the second long wall portion 411b of the support body 4. As a result, as shown in Figure 11, the second long wall portion 411b of the support body 4 and the first extending surface 551 of the mounting member 5 are roughly flush with each other, thereby preventing interference between the support body 4 and the lid body 12.

In addition, since the receiving portion 51 of the mounting member 5 is positioned at a position offset from the center of the short side of the housing 41 of the support body 4, the discharge hole 512 of the receiving portion 51 is not located directly below the guide plate 46, and the cone-shaped bottom surface of the recess 511 of the receiving portion 51 is located instead. Therefore, the chemical solution running down the guide plate 46 drips onto the cone-shaped bottom surface.

Next, the mounting member 5 is attached to the water storage tank. First, the lid 12 is shifted from the tank body 11 to expose the upper edge 111 of the tank body 11. Next, as shown in FIG. 12, the fixing portion 53 is attached so as to straddle the edge 111 of the tank body 11 from above. At this time, the abutment surface 554 of the mounting member 5 abuts against the outer surface of the edge 111 of the tank body 11, and the folded portion 54 presses against the inner wall surface of the edge 111. Therefore, the edge 111 of the tank body 11 is sandwiched between the abutment surface 554 and the folded portion 54, thereby fixing the mounting member 5 to the tank body 11. Next, as shown in FIG. 13, the lid 12 is attached to the tank body 11, and the fixing portion 53 is positioned between the first edge 121 and second edge 122 of the lid 12. Furthermore, the first edge 121 presses against the curved surface 552 and the second extending surface 553 of the mounting member 5 (these portions constitute the installation surface of the present invention). However, because the tube 6 is fitted into the first groove 556, the first edge 121 is prevented from pressing against the entire tube 6.

After the mounting member 5 is attached to the water storage tank 1 in this manner, the chemical container 2 is attached to the support 4 as shown in Figure 14. The connecting tube 33 of the chemical guide member 3 is inserted into the thin film portion 222 of the cap 22 of the chemical container 2, allowing the chemical solution to flow through the connecting tube 33 and into the receiving portion 42 of the support 4. The chemical solution then flows downward from the through hole 421 in the receiving portion 42 along the guide plate 46. The chemical solution drips from the lower end of the guide plate 46 into the recess 511 in the receiving portion 51 of the mounting member 5. At this time, the lower end of the guide plate 46 falls onto the cone-shaped bottom surface rather than the discharge hole 512 in the recess 511, and flows along the bottom surface and enters the discharge hole 512. The chemical solution that enters the discharge hole 512 flows into the tube 6 and is supplied from the tube 6 to the flushing water stored in the water storage tank 1.

In this way, the medicinal liquid stored in the water storage tank 1 along with the flush water provides a deodorizing and fragrant effect due to its aromatic components. Furthermore, the medicinal liquid poured into the toilet bowl from the water storage tank 1 during flushing cleans the toilet bowl, providing a deodorizing and fragrant effect. It is also possible to attach the medicinal liquid supply device to the water storage tank 1 after attaching the medicinal liquid container 2 to the support 4.

<6. Features>
The chemical liquid supply device configured as above can provide the following effects.
(1) This chemical supply device has a mounting member 5 that can be attached to the edge 111 of the tank body 11, so it can be attached to a water storage tank that is not provided with a water supply tray. In addition, a flexible tube 6 that guides the chemical solution from the chemical solution container 2 to the water storage tank 1 is supported on the mounting member 5, so that the chemical solution from the chemical solution container 2 can be stably supplied to the water storage tank 1 by this tube 6.

(2) Because the fixing portion 53 and the folded portion 54 are deformable, the mounting member 5 can be attached to the edge 111 of the tank body 11 of various widths. The example in Figure 14 described above shows a case where the edge 111 of the tank body 11 is narrow, that is, where the width of the edge 111 is shorter than the distance between the abutment surface 554 and the extension portion 532 of the fixing portion 53. However, when the edge 111 of the tank body 11 is wide, the mounting member 5 can be attached as follows.

As shown in Figure 15, when the width of the edge 111 of the tank body 11 is somewhat wide, the folded portion 54 is pressed by the edge 111, and the folded portion 54 comes into contact with the extending portion 532 of the fixing portion 53. The edge 111 of the tank body 11 is then sandwiched between the abutment surface 554 and the folded portion 54. In this case, the edge 111 of the tank body 11 is generally sandwiched by the elastic force of the fixing portion 53. In other words, when the width of the edge 111 of the tank body 11 is roughly the same as the distance between the extending portion 532 of the fixing portion 53 and the abutment surface 554, this type of sandwiching occurs.

As shown in Figure 16, if the edge 111 of the tank body 11 is wide, the curved fixing portion 53 is extended linearly, and the angle between the folded portion 54 and the extending portion 532 is widened so that they form approximately a 90-degree angle. This allows the edge 111 of the tank body 11 to be sandwiched between the abutment surface 554 and the folded portion 54. In other words, if the width of the edge 111 of the tank body 11 is longer than the distance between the extending portion 532 of the fixing portion 53 and the abutment surface 554, the edge 111 is sandwiched in this manner.

As shown in Figure 17, if an inward-extending flange 18 is formed on the edge 111 of the tank body 11, the curved fixing portion 53 is extended linearly and positioned along the upper surface of the flange 18. At this time, the folded portion 54 engages with the lower surface of the flange 18.

In this way, the mounting member 5 of this embodiment can be attached to the edge 111 of the tank body 11 of various widths.

(3) Because the fixing portion 53 has an upwardly convex curved portion 531, the fixing portion 53 can be positioned so that it rides over the edge 111 of the tank body 11. For example, as shown in FIG. 18 , if the fixing portion 8 extends in a straight line, the lid body 12 may ride up on the fixing portion 8, causing the lid body 12 to tilt, or the mounting member 5 may tilt. In contrast, by forming the fixing portion 53 as described above, the fixing portion 53 is positioned so that it rides over the edge 111 of the tank body 11, thereby suppressing interference between the mating portion between the tank body 11 and the lid body 12 and the fixing portion 53. As a result, the lid body 12 can be prevented from being positioned at an angle. Furthermore, because the mounting member 5 can be prevented from being positioned at an angle, the chemical solution container 2 can also be prevented from tilting.

In addition to the water storage tank 1 of the above-described configuration, the mounting member 5 can also be attached to the following water storage tank. In the example of Figure 19, only a first edge 121 extending downward is provided on the outer periphery of the lid 12, and this first edge 121 is in contact with the edge 111 of the tank body 11. In this case, the fixing part 53 is positioned so as to straddle the edge 111 of the tank body 11, making it possible to attach it. Furthermore, although the first edge 121 of the lid 12 presses against the curved part 531 of the fixing part 53, because the tube 6 is embedded in the second groove 533, the first edge 121 is prevented from pressing against the entire tube 6. This prevents the flow of the chemical solution from being obstructed.

In the example of Figure 20, a first edge 121 extending downward is provided on the outer peripheral edge of the lid body 12, and the width of this first edge 121 is wider than the edge 111 of the tank body 11. In addition, a protrusion 124 is formed at the lower end of the first edge 121 and is positioned on the inner surface side of the edge 111 of the tank body 11. In this case, too, the fixing portion 53 is positioned so as to straddle the edge 111 of the tank body 11, and therefore can be attached.

In the example of Figure 21, a first edge 121 extending downward is provided on the outer peripheral edge of the lid body 12, and the width of this first edge 121 is wider than the edge 111 of the tank body 11. Meanwhile, a protrusion 112 protruding upward is formed on the outer side of the upper end surface of the edge 111 of the tank body 11. Furthermore, a protrusion 125 is formed at the lower end of the first edge 121 and is positioned on the inner side of the edge 111 of the tank body 11, and this protrusion 125 is positioned inside the protrusion 112 of the tank body 11. In this case too, the fixing portion 53 is positioned so as to straddle the edge 111 of the tank body 11, and therefore can be attached.

In the example of Figure 22, a first edge 121 extending downward is provided on the outer peripheral edge of the lid body 12. Meanwhile, a protrusion 113 protruding upward is formed on the inside of the upper end surface of the edge 111 of the tank body 11. The first edge 121 is then positioned on the outer surface side of the protrusion 113 of the tank body 11. In this case too, the fixing portion 53 is positioned so as to straddle the edge 111 of the tank body 11, and therefore can be attached.

In this way, the mounting member 5 of this embodiment can be attached to water tanks 1 of various types.

(4) In the above example, since the lid body 12 protrudes from the tank body 11, the receiving portion 51 of the mounting member 5 is fitted into the support body 4 so that the second long wall portion 411b of the support body 4 faces the fixed portion 53 of the mounting member 5 (second position). This prevents interference between the support body 4 and the lid body 12. On the other hand, when the side of the lid body 12 and the side of the tank body 11 are roughly flush with each other as shown in FIG. 23, the receiving portion 51 of the mounting member 5 is fitted into the support body 4 so that the first long wall portion 411a of the support body 4 faces the fixed portion 53 of the mounting member 5 (first position). This causes the first long wall portion 411a of the support body 4 to protrude toward the water storage tank 1 more than the first extension surface 551 of the mounting member 5, preventing the support body 4 and the lid body 12 from becoming too far apart.

In this way, with the mounting member 5 and support body 4 according to this embodiment, the orientation of the support body 4 relative to the mounting member 5 can be changed depending on whether or not the lid body 12 protrudes. This makes it possible to prevent interference between the lid body 12 and the support body 4, or to position the lid body 12 and the support body 4 so that they are not too far apart.

(5) Because the tube 6 is supported by the mounting member 5 so that it is positioned below the discharge hole of the receiving part, the following effects can be obtained. For example, as shown in Figure 24, if a portion of the tube is positioned above the discharge hole of the receiving part, the medicinal liquid dripping from the discharge hole will accumulate between the portion of the tube positioned above the discharge hole and the discharge hole, and there is a risk that the accumulated medicinal liquid will flow out all at once due to the siphon principle.

On the other hand, as shown in Figure 25, if the tube 6 is positioned below the discharge hole 512 of the receiving portion 51, the chemical solution dripping from the guide plate 46 onto the receiving portion 51 enters the tube 6 alternately with air, allowing the chemical solution to be supplied little by little from the tube 6 into the water storage tank 1.

(6) In the mounting member 5, the guide member 557 on which the tube 6 is placed, the curved surface 552, the second extension surface 553, and the fixing portion 53 are formed by curved or flat surfaces and therefore do not have corners. Therefore, bending of the tube 6 can be prevented. As a result, kinking of the tube 6 can be suppressed, allowing the medicinal solution to flow smoothly through the tube 6.

(7) The guide plate 46 faces the second long wall portion 411b inside the housing 41 of the support body 4. Therefore, a portion of the medicinal liquid flowing along the guide plate 46 volatilizes on the guide plate 46. As a result, the aromatic components flow to the outside through the opening 413 of the housing, thereby achieving an aromatic effect.

(8) The discharge hole 512 of the receiving portion 51 is not located directly below the guide plate 46 of the support 4, but rather the mortar-shaped bottom surface of the recess 511 of the receiving portion 51. Therefore, the medicinal liquid running down the guide plate 46 does not directly enter the discharge hole 512, but drips onto the mortar-shaped bottom surface. As a result, part of the medicinal liquid evaporates on this bottom surface, thereby achieving an aromatic effect.

(9) Even if the lid 12 is installed on the mounting member 5 and the tube 6 is pressed by the lid 12, the tube 6 is not completely crushed because it is housed in the groove at that location (the installation section). Therefore, the medicinal solution can flow smoothly through the tube 6. In addition, because the mounting member 5 is flexible, the groove is reduced in diameter when pressed by the lid 12. This brings the inner wall surface of the groove into tight contact with the tube 6, allowing the tube 6 to be firmly fixed to the groove.

7. Modifications
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, the following modifications are possible. Furthermore, the gist of the following modifications can be combined as appropriate.

<7-1>
In the above embodiment, a chemical solution guide member 3 and a support body 4 are provided, but as long as the chemical solution discharged from the chemical solution container 2 is supplied to the water storage tank 1 via a tube 6, the chemical solution container 1 is supported by the support body 4, and the mounting member 5 can be attached to the support body 4, the configuration of the support body 4 can be changed as appropriate, and the chemical solution guide member 3 is not necessarily required.

<7-2>
In the above embodiment, the support body 4 is provided with a fixed plate 44 in the internal space of the support body 4, and the receiving portion 51 of the mounting member 5 is fitted between the fixed plate 44 and the second long wall portion 411b of the housing 4 so that the support body 4 can take the first position and the second position of the present invention. However, the configuration of the support body 4 is not particularly limited as long as the support body 4 can take the first position and the second position of the present invention. For example, it is sufficient if a positioning portion is provided so that the receiving portion 51 of the mounting member 5 can move in the short direction in the internal space of the support body 4. Alternatively, the support body 4 may have a structure that rotates relative to the mounting member 5, thereby taking the first and second positions.

<7-3>
The configuration of the mounting member 5 for mounting to the water tank 1 is not particularly limited, as long as the mounting member 5 is configured to be mounted at least between the tank body 11 and the lid 12 of the water tank 1. Therefore, for example, the configuration of the fixing portion 53 can be changed as appropriate.

<7-4>
The tube 6 may be attached to any position on the attachment member 5, and does not have to be attached along the contact portion 52 and the fixing portion 53 as in the above embodiment.
