[0015] Hereinafter, chemical solution supply devices according to several embodiments of the present invention will be described with reference to the drawings.

[0016] 1. First Embodiment <1-1. Overview of the chemical supply device> FIG. 1 is a front view of a liquid medicine supplying device 100 according to a first embodiment of the present invention, FIG. 2 is an exploded view thereof, and FIG. 3 is a diagram showing a typical installation example of the liquid medicine supplying device 100. The liquid medicine supplying device 100 is a device that supplies liquid medicine to a toilet bowl, and as shown in these figures, includes a container 1 that contains the liquid medicine to be supplied to the toilet bowl, and a tube 2 connected to the container 1. In the description herein, unless otherwise specified, "top (top surface)," "bottom (bottom surface)," "left," and "right" are defined as shown in FIGS. 1 and 2, "front" means the near side in FIGS. 1 and 2, and "rear (back surface)" means the far side in FIGS. 1 and 2.

[0017] The chemical liquid supplying device 100 is installed near the water storage tank 9 so as to supply the chemical liquid into the water storage tank 9, which supplies flush water into the toilet bowl. The water storage tank 9 includes a tank body 91 with an open top, and a lid 92 that covers the opening at the top of the tank body 91. As shown in FIG. 3 , the chemical liquid supplying device 100 is installed so that the container 1 is placed on the top surface of the lid 92 of the water storage tank 9, and the tube 2 is sandwiched between the tank body 91 and the lid 92. Note that the top surface of the lid 92 here forms a substantially horizontal plane, and no water supply tray for hand washing is placed on the top of the lid 92.

[0018] The chemical solution supplying device 100 of this embodiment further includes a spacer 3. The tube 2 defines a passage S2 therein that guides the chemical solution contained in the container 1 into the water storage tank 9. The spacer 3, like the tube 2, is disposed so as to be sandwiched between the tank body 91 and the lid 92 in order to prevent clogging of the passage S2 for the chemical solution in the tube 2.

[0019] Moreover, the drug solution supply device 100 of this embodiment further includes a connection member 4 connected to the container 1 and the tube 2. The tube 2 is indirectly connected to the container 1 via the connection member 4. The connection member 4 plays a role in controlling the amount of drug solution supplied from the container 1, as will be described in detail later.

[0020] The chemical solution contains one or more elements selected from the group including a cleaning agent, a disinfectant, a deodorizer, and an air freshener, and may also contain a coloring agent. The chemical solution is mixed with flush water to provide the effects of the ingredients contained in the chemical solution to the inside of the toilet bowl or the inside of the 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 an air freshener, it can eliminate unpleasant odors and fill the toilet room with a pleasant fragrance.

[0021] <1-2. Configuration of each part> <1-2-1. Container> 1 to 3, the container 1 has a container body 10 having an internal space S1 for accommodating a medicinal solution, and a cap 12 that closes the internal space S1. The shape of the container body 10 is not particularly limited, but in this embodiment, the container body 10 has a dome shape that is slightly flattened in the left-right direction and whose width in the left-right direction is greater than its width in the depth direction.

[0022] The container body 10 has an outlet 11 at the center of its lower portion that connects the internal space S1 with the external space, and the outlet 11 is cylindrical and extends in the vertical direction. The cap 12 is fixed to the outlet 11 so as to cover and close it. In Figure 2, a cross section of the outlet 11 and the cap 12 taken along a plane that passes through the central axis of the outlet 11 and is parallel to the left-right direction is shown, with part of the cross section shown by a dotted line, for reference.

[0023] The material constituting the container 1 is not particularly limited, but typically, a hard resin or metal can be used. For example, the container body 10 can be preferably made of a synthetic resin such as polyethylene terephthalate, polyethylene, or polypropylene. The same applies to the cap 12.

[0024] <1-2-2. Connection parts> 4A to 4D are views of the connection member 4 viewed from various directions. The connection member 4 is disposed between the container 1 and the tube 2 so as to connect them.

[0025] As shown in FIGS. 4A and 4C , the connecting member 4 has a rectangular base 40 and a cylindrical puncture portion 41 that rises from the center of the upper surface of the base 40. The puncture portion 41 has a shape in which the top of a vertically extending cylinder is cut off at an angle, and the top is sharp. The puncture portion 41 is inserted into the outlet 11 of the container 1 by piercing the bottom surface of the cap 12 of the container 1 from below. The connecting member 4 further has a cylindrical peripheral wall portion 42 that rises from the upper surface of the base 40 at a distance from the puncture portion 41 and surrounds the puncture portion 41. The annular space surrounded by the outer surface of the puncture portion 41 and the inner surface of the peripheral wall portion 42 receives the cap 12 and the outlet 11 of the container 1. At this time, the outer surface of the cap 12 and the inner surface of the peripheral wall portion 42 come into close contact with each other, and the frictional force generated between them secures the connecting member 4 to the container 1.

[0026] 4B and 4D, the connecting member 4 further includes a thin, cylindrical rod 43 that hangs down from the center of the underside of the base 40. A fine groove S4 is formed on the outer surface of the rod 43, extending vertically along the entire length of the rod 43. The fine groove S4 extends not only through the rod 43 but also through the base 40, and communicates with the space S3 inside the puncturing portion 41. Therefore, when the puncturing portion 41 breaks through the cap 12 and the container 1 and the connecting member 4 are connected, the fine groove S4 communicates with the internal space S1 of the container 1 via the space S3 inside the puncturing portion 41, and serves as a passageway for the medicinal liquid delivered from the internal space S1. In this embodiment, the cross section of the fine groove S4 is V-shaped with a sharp point at the bottom.

[0027] One end of the rod 43 is inserted into the passage S2 inside the tube 2. At this time, the inner surface of the tube 2 and the outer surface of the rod 43 come into close contact, and the frictional force generated between them fixes the tube 2 to the connecting member 4. As a result, the microgroove S4 and the passage S2 are connected, and the drug solution delivered from the internal space S1 passes through the microgroove S4 and is then delivered to the passage S2. At this time, the drug solution flows slowly from the internal space S1 into the microgroove S4 and further into the passage S2 due to gravity and the action of capillary action.

[0028] The connecting member 4 further has a cylindrical peripheral wall portion 44, which hangs down from the underside of the base 40 at a distance from the rod body 43 and surrounds the rod body 43. The annular space surrounded by the outer surface of the rod body 43 and the inner surface of the peripheral wall portion 44 receives one end of the tube 2 attached to the rod body 43.

[0029] As described above, the connecting member 4 indirectly connects the internal space S1 of the container 1 to the passage S2 in the tube 2, receives the chemical solution from the internal space S1, and supplies it to the passage S2. By appropriately adjusting the cross-sectional area of ​​the fine grooves S4, the connecting member 4 can control the amount of chemical solution supplied from the container 1, and stably supplies the chemical solution at a desired flow rate to the passage S2 in the tube 2 further downstream, and ultimately to the water storage tank 9.

[0030] In addition, a support member 45 is connected to the connecting member 4, which supports the container 1 so that it is placed on the lid 92 of the water storage tank 9. The support member 45 serves to support the container 1 so that it is stably placed in a predetermined position. The connecting member 4 and the support member 45 may be formed integrally, or may be formed separately and then connected. In this embodiment, the support member 45 is composed of a plurality of legs hanging down from the underside of the base 40, and these legs extend in the vertical direction and are located at the four corners of the approximately rectangular base 40. As shown in FIG. 3 , these legs constituting the support member 45 are installed so as to stand on the upper surface of the lid 92 of the water storage tank 9, and support the container 1 so that it is stably placed on the upper surface of the lid 92.

[0031] The materials constituting the connecting member 4 and the supporting member 45 are not particularly limited, but typically, hard resin or metal can be used. For example, the connecting member 4 can be preferably made of a synthetic resin such as polypropylene, polyethylene, or polyethylene terephthalate. The same is true for the supporting member 45.

[0032] <1-2-3. Tube> The tube 2 defines a passage S2 therein through which the medicinal liquid flows. As described above, one end of the tube 2 is connected to the rod body 43 of the connecting member 4 so as to cover it from the outside. Also, as described above, when one end of the tube 2 is connected to the rod body 43 and the container 1 is connected to the puncture portion 41, the passage S2 communicates with the internal space S1 of the container 1 via the space S3 inside the puncture portion 41 and the microgroove S4. Also, as shown in FIG. 3 , the middle portion of the tube 2 is sandwiched between the tank body 91 and the lid 92, and the other end is contained in the water storage tank 9. Therefore, the passage S2 can guide the medicinal liquid delivered from the internal space S1 into the water storage tank 9.

[0033] The tube 2 is flexible and can be deformed into various shapes. Therefore, the tube 2 can be bent freely, and therefore, wherever the container 1 is installed, the container 1 can be connected to the inside of the water storage tank 9 via the connecting member 4. As described above, the chemical solution supply device 100 can easily secure an installation location and can stably supply the chemical solution from the inside of the container 1 to the inside of the water storage tank 9.

[0034] The material constituting the tube 2 is not particularly limited as long as it is flexible, but typically rubber, thermoplastic elastomer, or soft resin can be used. For example, the tube 2 is preferably made of silicone rubber. The contact angle of the chemical solution with the material of the inner surface of the tube 2 is preferably 90° or less. In this case, the chemical solution can flow through the tube 2 at an appropriate speed, neither too fast nor too slow.

[0035] <1-2-4. Spacer> As shown in Fig. 3, the spacer 3 is installed so as to be sandwiched between the tank body 91 and the lid 92 of the water storage tank 9, similar to the tube 2. The spacer 3 has a constant thickness in the vertical direction and maintains the gap between the tank body 91 and the lid 92. The number of spacers 3 is not particularly limited. One or more spacers 3 may be arranged only near the tube 2 in the annular upper part of the tank body 91, or multiple spacers 3 may be arranged at predetermined intervals in the circumferential direction of the annular upper part of the tank body 91.

[0036] 3, the spacer 3 has a recess on its underside, which receives the upper part of the tank body 91 and covers it from above. Therefore, the spacer 3 is firmly caught on the upper part of the tank body 91 and will not easily fall off the tank body 91.

[0037] As described above, the tube 2 is flexible. However, even when the tube 2 is sandwiched between the tank body 91 and the lid 92, the spacer 3 ensures a space for the tube 2 to be disposed therebetween, so the tube 2 is not excessively crushed or is not crushed at all due to the weight of the lid 92. This prevents the passage S2 from being blocked and preventing the flow of the chemical solution through the passage S2. Furthermore, by adjusting the number and arrangement of the spacers 3, it is possible to prevent the lid 92 from rattling relative to the tank body 91 due to the thickness of the tube 2 sandwiched between the tank body 91 and the lid 92.

[0038] The material constituting the spacer 3 is not particularly limited, but typically, hard resin, rubber, or thermoplastic elastomer can be used.

[0039] 2. Second Embodiment <2-1. Overview of the chemical supply device> FIG. 5 is a front view of a medicinal liquid supplying device 200 according to a second embodiment of the present invention, FIG. 6 is an exploded view thereof, and FIG. 7 is a diagram showing a typical installation example of the medicinal liquid supplying device 200. Like the medicinal liquid supplying device 100, the medicinal liquid supplying device 200 is also a device that supplies medicinal liquid to a toilet bowl. In the following description, elements common to the medicinal liquid supplying devices 100 and 200 are given the same reference numerals, and description thereof will be omitted as appropriate. In this description, unless otherwise specified, "top (top surface)," "bottom (bottom surface)," "left," and "right" are defined as shown in FIGS. 5 and 6, "front" means the front side of FIGS. 5 and 6, and "rear (back surface)" means the back side of FIGS. 5 and 6.

[0040] As shown in FIGS. 5 to 7, chemical solution supplying device 200 also includes container 1 for storing chemical solution and tube 2 connected to container 1, and is installed around water storage tank 9 so that chemical solution can be supplied into water storage tank 9. As shown in FIG. 7, chemical solution supplying device 200 is also installed so that container 1 is placed on the upper surface of lid 92 of water storage tank 9 and tube 2 is sandwiched between tank body 91 and lid 92. Chemical solution supplying device 200 also further includes spacer 3 sandwiched between tank body 91 and lid 92 to prevent clogging of passage S2 in tube 2. Spacer 3 can also prevent lid 92 from rattling relative to tank body 91 due to the thickness of tube 2.

[0041] On the other hand, the drug solution supply device 200 further includes a cover member 5, a lower container 6, and a reservoir 7, which are arranged between the container 1 and the tube 2, instead of the connecting member 4. The tube 2 is indirectly connected to the container 1 via these elements 5 to 7. These elements 5 to 7 collectively function as a connecting member that connects the container 1 and the tube 2, and, like the connecting member 4, play a role in controlling the amount of drug solution supplied from the container 1.

[0042] <2-2. Configuration of each part> The cover member 5, the lower container 6, and the reservoir 7 will be described in detail below in order.

[0043] <2-2-1. Cover parts> As shown in FIG. 6 , the cover member 5 has a circular plate-shaped base 50 and a cylindrical puncturing portion 51 rising from the center of the upper surface of the base 50. In FIG. 6 , a cross section of the cover member 5 and the lower container 6 taken along a plane passing through the central axis of the puncturing portion 51 and parallel to the left-right direction is shown partially in dotted lines for reference. The puncturing portion 51 has a shape in which the top of a vertically extending cylinder is cut off at an angle, and the top is sharp. The puncturing portion 51 is inserted into the discharge port 11 by breaking through the bottom surface of the cap 12 of the container 1 from below. The cover member 5 further has a cylindrical peripheral wall portion 52, which rises upward from the outer periphery of the base 50 at a distance from the puncturing portion 51 and surrounds the puncturing portion 51. The annular space surrounded by the outer surface of the puncture portion 51 and the inner surface of the peripheral wall portion 52 receives the cap 12 and the outlet portion 11 of the container 1 .

[0044] The cover member 5 also has a cylindrical port member 53 that hangs down from the center of the underside of the base 50. A small opening is formed in the center of the base 50, and the port member 53 is arranged to surround the opening. Therefore, the space S21 inside the puncture portion 51 communicates with the space S22 inside the port member 53. The port member 53 has a smaller diameter than the puncture portion 51.

[0045] The cover member 5 further has an annular top surface 54 that is continuous with the upper edge of the peripheral wall 52 and extends radially outward from the upper edge. The outer peripheral edge of the top surface 54 is rectangular. The cover member 5 also has a peripheral wall 55 that hangs down from the outer peripheral edge of the top surface 54. The peripheral wall 55 is rectangular tubular. A pair of left and right protrusions 55a protrude radially outward from the vicinity of the lower part of the left and right wall portions of the peripheral wall 55. These protrusions 55a connect the lower container 6 and the cover member 5 by being hooked onto a pair of left and right claws 64 of the lower container 6, which will be described later.

[0046] The material constituting the cover member 5 is not particularly limited, but typically, a hard resin or metal can be used. For example, the cover member 5 can be preferably made of a synthetic resin such as polypropylene, polyethylene, or polyethylene terephthalate.

[0047] <2-2-2. Lower container> The lower container 6 is a dish-shaped container that receives the lower portion of the container 1, including the outlet 11 and the cap 12, from below. The lower container 6 has a bottom 61 and an outer wall 62 that rises upward and outward from the bottom 61. The lower container 6 further has a rectangular cylindrical peripheral wall 63 that rises from the upper surface of the bottom 61 inside the outer wall 62, and the cover member 5 is housed in the space inside the peripheral wall 63. At this time, the peripheral wall 63 is received in the rectangular annular space surrounded by the outer surface of the peripheral wall 52 and the inner surface of the peripheral wall 55 of the cover member 5. A pair of left and right claws 64 rise from the upper surface of the bottom 61 at positions spaced apart from the peripheral wall 63. These claws 64 hook onto the protrusions 55a of the cover member 5, thereby fixing the lower container 6 to the cover member 5. Therefore, the lower container 6 will not fall off the cover member 5 unintentionally.

[0048] The lower container 6 further has a plate member 65 hanging down from the center of the lower surface of the bottom portion 61. The plate member 65 has a width that extends left and right and a thickness that extends front and rear. A cylindrical protrusion 66 stands up from the center of the upper surface of the plate member 65. An opening is formed in the center of the bottom portion 61. The protrusion 66 extends in the vertical direction so as to pass through the opening in the center of the bottom portion 61. The protrusion 66 has a shape in which the top of a cylinder extending in the vertical direction has been cut off diagonally, and the top is sharp. A number of fine grooves S25 extending in the vertical direction are formed on the front and rear surfaces of the plate member 65.

[0049] When the cover member 5 is housed in the space inside the peripheral wall portion 63 and the lower container 6 and the cover member 5 are connected, the protrusion 66 is inserted into the space S22 inside the port member 53. A fine groove S24 extending in the vertical direction is formed on the outer surface of the protrusion 66 over the entire length of the protrusion 66. Therefore, when the lower container 6 and the cover member 5 are connected and the puncturing portion 51 breaks through the cap 12, and the container 1 and the cover member 5 are connected, the fine groove S24 communicates with the internal space S1 of the container 1. More specifically, the fine groove S24 communicates with the internal space S1 of the container 1 via the space S21 inside the puncturing portion 51, and serves as a passage through which the medicinal liquid delivered from the internal space S1 flows.

[0050] The drug solution delivered from the internal space S1 passes through the microgroove S24, reaches the plate member 65 below the protrusion 66, and flows into the microgroove S25 of the plate member 65. At this time, the drug solution flows slowly from the internal space S1 into the microgroove S24 and further into the microgroove S25 due to gravity and the action of capillary action. The drug solution that reaches the lower end of the microgroove S25 of the plate member 65 then drops from the plate member 65 and is stored in the reservoir 7. The microgroove S25 also serves as a passage through which the drug solution delivered from the internal space S1 flows.

[0051] The lower container 6 further has a rectangular cylindrical peripheral wall portion 67, which is spaced apart from the plate member 65 and hangs down from the underside of the bottom portion 61 so as to surround the plate member 65. A pair of front and rear rods 68 extending in the vertical direction are disposed at the center of the front and rear surfaces of the peripheral wall portion 67. The pair of front and rear rods 68 are used to position the lower container 6 relative to the reservoir 7, as will be described in detail later.

[0052] The lower container 6 also has a support portion 69 extending downward from the outer wall portion 62. In this embodiment, the support portion 69 is composed of a plurality of legs that extend in the vertical direction, with two legs arranged at a fixed interval in the left-right direction on the lower front surface of the outer wall portion 62, and two more legs arranged at a fixed interval in the left-right direction on the lower rear surface of the outer wall portion 62.

[0053] As will be described in detail later, in this embodiment, a reservoir 7 is disposed below the lower container 6, and the container 1 is placed on the lid 92 of the water storage tank 9 via this reservoir 7. However, if the lid 92 has a water supply tray for hand washing, the container 1 can be placed on the water supply tray using only the cover member 5 and the lower container 6 without using the reservoir 7. At this time, the pair of front and rear rods 68, together with the plate member 65, are inserted into an opening formed in the water supply tray that allows flush water to flow into the water storage tank 9. At this time, the multiple legs constituting the support portion 69 are placed so as to stand on the water supply tray. The support portion 69 supports the container 1 so that the container 1 is stably placed in the water supply tray.

[0054] Although there are no particular limitations on the material that constitutes the lower container 6, typically, a hard resin or metal can be used. For example, the lower container 6 can be preferably made of a synthetic resin such as polypropylene, polyethylene, or polyethylene terephthalate.

[0055] <2-2-3. Reservoir> The reservoir 7 is box-shaped with an open top and has a storage space S26 therein for storing the medicinal liquid. The reservoir 7 is disposed below the lower container 6, receives the medicinal liquid from the internal space S1 of the container 1 via the cover member 5 and the lower container 6, and temporarily stores it in the storage space S26.

[0056] Fig. 8 is a cross-sectional view taken along line VIII-VIII in Fig. 6. The reservoir 7 has a rectangular bottom surface portion 70, and a front wall portion 71, a rear wall portion 72, a left wall portion 73, and a right wall portion 74 that stand up from the front edge, rear edge, left edge, and right edge, respectively, of the bottom surface portion 70. The reservoir 7 also has a rectangular annular flange 76 that continues from the upper edges of these walls 71 to 74.

[0057] A pair of front and rear recesses 75 extending in the up-down direction are formed in the left-right center on the inner surfaces of the front wall 71 and the rear wall 72. The pair of front and rear rods 68 of the lower container 6 are inserted into these recesses 75, thereby positioning and connecting the lower container 6 to the reservoir 7. At this time, the bottom surface 61 of the lower container 6 is placed on the upper surface of the flange 76. At this time, the multiple legs constituting the support part 69 are positioned so as not to interfere with the flange 76, as shown in FIG. 5.

[0058] An outlet is formed in the right wall portion 74 of the reservoir 7 near the bottom surface portion 70, and the tube 2 is inserted into the outlet. The tube 2 is fixed to the reservoir 7 by a fixing means (not shown). As described above, the tube 2 is connected to the reservoir 7 so that the passage S2 therein communicates with the storage space S26.

[0059] When the reservoir 7 and the lower container 6 are connected, the plate member 65 and the peripheral wall portion 67 of the lower container 6 are received in the storage space S26. As described above, the chemical solution is sent from the internal space S1 of the container 1, travels through various paths, and reaches the fine grooves S25 of the plate member 65 of the lower container 6. The chemical solution then flows downward along the fine grooves S25 and drops from the fine grooves S25 into the reservoir 7. The reservoir 7 supplies the chemical solution thus stored in the storage space S26 to the passage S2 in the tube 2 via the outlet in the right wall portion 74. The chemical solution then passes through the passage S2 and is finally guided into the water storage tank 9.

[0060] The material constituting the reservoir 7 is not particularly limited, but typically, a hard resin or metal can be used. For example, the reservoir 7 can be preferably made of a synthetic resin such as polypropylene, polyethylene, or polyethylene terephthalate.

[0061] As described above, the cover member 5, the lower container 6, and the reservoir 7 indirectly connect the internal space S1 of the container 1 to the passage S2 in the tube 2. These elements 5-7 receive the chemical solution from the internal space S1 and supply it to the passage S2. These elements 5-7 can control the amount of chemical solution supplied from the container 1 by appropriately adjusting the cross-sectional areas of the fine grooves S24 and S25 through which the chemical solution passes, and stably supply the chemical solution at a desired flow rate to the downstream passage S2 and ultimately into the water storage tank 9. Furthermore, like the chemical solution supply device 100, the chemical solution supply device 200 also has a flexible tube 2, so that it is easy to secure an installation location.

[0062] <3. Modifications> Although several embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, 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.

[0063] <3-1> In the above embodiment, the container 1 is installed on the lid 92 of the water storage tank 9, and the tube 2 is installed so as to be sandwiched between the tank body 91 and the lid 92. However, the installation manner of the chemical solution supply devices 100 and 200 is not limited to this example, and they can be installed in various places.

[0064] For example, as shown in Fig. 9, the container 1 may be placed on the side of the water storage tank 9. In this case, it is preferable to appropriately modify the support member 45 into a shape that can support the container 1 so that it can be placed on the side of the water storage tank 9.

[0065] 10, the container 1 may be placed on the side of the toilet bowl 8, with one end of the tube 2 housed within the toilet bowl 8. In this case, the passage S2 within the tube 2 can guide the chemical solution directly into the toilet bowl 8 without passing through the water tank 9. In this case, it is preferable to appropriately modify the support member 45 into a shape that can support the container 1 so that it can be placed on the side of the toilet bowl 8. In this case, the tube 2 can be placed so that it is sandwiched between the rim 81 of the toilet bowl 8 and a toilet seat 82 attached to the toilet bowl 8. In this case, it is preferable that the spacer 3, like the tube 2, be placed so that it is sandwiched between the rim 81 of the toilet bowl 8 and the toilet seat 82.

[0066] 9 and 10 show modified examples of the liquid medicine supplying device 100, the liquid medicine supplying device 200 can also be modified so that the container 1 can be installed on the side of the water storage tank 9 or the side of the toilet bowl 8. In this case, the liquid medicine supplying device 200 may also be provided with a support member that performs the same function as the support member 45.

[0067] <3-2> In the above embodiment, the spacer 3 can be omitted. In this case, the tube 2 may be configured to have partial rigidity at the portion sandwiched between the tank body 91 and the lid 92 (or between the rim 81 of the toilet bowl 8 and the toilet seat 82) so that the portion is not crushed.

[0068] Alternatively, as shown in Figure 11, a rigid guard member 21 may be attached to the tube 2 so that the portion of the tube 2 sandwiched between the tank body 91 and the lid 92 (or between the rim 81 of the toilet bowl 8 and the toilet seat 82) does not collapse. For example, the guard member 21 may be made of a hard material such as a hard resin, and may be realized as a tubular member into which the tube 2 is inserted. In this case, it is preferable that the guard member 21 be freely slidable along the longitudinal direction of the tube 2.

[0069] <3-3> In the first embodiment, the connecting member 4 may be omitted, and the tube 2 may be directly connected to the outlet portion 11 of the container 1. Similarly, in the second embodiment, the cover member 5, the lower container 6, and the reservoir 7 may be omitted, and the tube 2 may be directly connected to the outlet portion 11 of the container 1.
