[0001] The present invention relates to a drug solution supplying device. [Background technology]

[0002] In recent years, toilets have become increasingly tankless, and a chemical liquid supplying device that is attached to the rim of a toilet bowl to supply a cleaning agent or an aromatic agent into the toilet bowl is known, as described in Patent Document 1. The chemical liquid supplying device described in Patent Document 1 has a chemical liquid container, a chemical liquid guide member that guides the chemical liquid discharged from the chemical liquid container to a support, a support that receives the chemical liquid, and a mounting member that mounts the chemical liquid supplying device to the toilet bowl (see Figures 27 and 28 of Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-51869 A Summary of the Invention [Problem to be solved by the invention]

[0004] Here, the attachment member in the invention described in Patent Document 1 is a belt-shaped member that is initially curled and abuts the inner, top, and outer surfaces of the edge of the toilet bowl to attach the drug solution supplying device to the toilet bowl. This allows the drug solution supplying device to be attached even if the width of the edge to be attached is different. However, since this belt-shaped member can easily be deformed from a curled state to a straight state, it has a small restoring force and the attachment stability of the drug solution supplying device is not high.

[0005] The present invention has been made in consideration of the above problems, and an object of the present invention is to provide a medicinal liquid supplying device that can be attached to the rim of a toilet bowl with high stability. [Means for solving the problem]

[0006] According to one aspect of the present invention, there is provided a chemical liquid supplying device that supplies a chemical liquid into a toilet bowl, the chemical liquid supplying device comprising a fixing member that is attached to the edge of the toilet, the fixing member having a holding portion that holds a chemical liquid container filled with chemical liquid, an inner arm including an inner abutment portion that abuts against the inside of the edge of the toilet, and an outer arm including a sloping portion that extends diagonally downward inward from the holding portion or the inner arm, and an outer abutment portion that extends upward from the sloping portion and abuts against the outside of the edge of the toilet, the base end of the sloping portion on the connection side to the holding portion or inner arm is formed into an outwardly convex curved shape.

[0007] According to the above aspect, the medicinal liquid supplying device is attached by clamping the edge of the toilet bowl between the inner abutment portion of the inner arm and the outer abutment portion of the outer arm, so that it can be stably attached to the toilet bowl. Furthermore, since the base end of the inclined portion has an outwardly convex curved shape, the outer arm can be significantly bent outward, so that the medicinal liquid supplying device can be attached to the toilet bowl regardless of the width of the edge of the toilet bowl.

[0008] According to one aspect of the present invention, the tip end portion of the inclined portion on the connection side to the outer contact portion is formed into an inwardly convex curved shape.

[0009] According to the above aspect, since the tip of the inclined portion has an inwardly convex curved shape, the outer abutment portion can be deflected significantly relative to the inclined portion, and the medicinal liquid supply device can be attached to the toilet even if the edge width is wider.

[0010] According to one aspect of the present invention, the holding portion or the connection portion to the inner arm is formed in a curved shape that continues to the base end of the inclined portion.

[0011] According to the above aspect, it is possible to prevent a large load from acting locally on the connection portion when the outer arm deforms, and to prevent the outer arm from being damaged.

[0012] According to one aspect of the invention, the abutment surface of the inner abutment portion is angled relative to the abutment surface of the outer abutment portion so as to diverge toward the rear of the toilet bowl.

[0013] When mounting the drug supply device, it is preferable to mount it on the edge of the rear side of the toilet bowl so as not to hinder the user, and in such a portion the width of the rim increases toward the rear. In contrast, according to the above embodiment, the contact surface of the inner contact part is angled so as to increase in width toward the rear relative to the contact surface of the outer contact part, so that the drug supply device can be stably mounted on the edge of the toilet bowl.

[0014] According to one aspect of the present invention, the contact surface of the inner contact portion is inclined inwardly and rearward with respect to a direction perpendicular to the direction in which the inner arm extends.

[0015] As described above, when attaching the drug solution dispenser, it is preferable to attach it to the edge of the rear side of the toilet bowl, and in such a portion, the inner surface of the rim is inclined inward toward the rear. In contrast, according to the above embodiment, the abutment surface of the inner abutment part is inclined inward toward the rear with respect to a direction perpendicular to the direction in which the inner arm extends, so that the inner arm extends inward and outward, preventing the drug solution container from interfering with the lid or toilet seat.

[0016] According to one aspect of the present invention, the outer contact portion has a vertical cross-sectional shape that is curved and convex outward.

[0017] The outer surface of the toilet has a vertical cross-sectional shape that is curved and convex outward. In contrast, according to one aspect of the present invention, the outer contact portion can be made to contact the outer surface of the toilet so as to conform to the outer surface.

[0018] According to one aspect of the invention, the inner arm includes a base end extending from the retaining portion, the inner abutment portion extending from the base end, and a width of the base portion is between 15 mm and 50 mm.

[0019] According to the above aspect, the base abuts against the edge of the rim of the toilet over a wide area, so that the medicinal liquid supplying device can be stably attached to the edge of the toilet.

[0020] According to one aspect of the invention, the device includes a tube that dispenses the liquid medicine supplied from the liquid medicine container into the bowl, the tube extending within a recess formed in the rear side of the inner arm.

[0021] According to the above aspect, the recess that houses the tube faces rearward, so that when a person urinates in the toilet, dirt can be prevented from accumulating in the recess.

[0022] According to one aspect of the present invention, there is provided the following aspect of the invention. Item 1. A medicinal liquid supplying device that supplies medicinal liquid into the bowl of a toilet, comprising a fixing member that is attached to the edge of the toilet, the fixing member having a holding portion that holds a medicinal liquid container filled with medicinal liquid, an inner arm including an inner abutment portion that abuts against the inside of the edge of the toilet, and an outer arm including a sloping portion that extends diagonally downward inward from the holding portion or the inner arm, and an outer abutment portion that extends upward from the sloping portion and abuts against the outside of the edge of the toilet, the base end of the sloping portion on the side of the connection to the holding portion or inner arm is formed in an outwardly convex curved shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] Hereinafter, a first embodiment of a drug solution supplying device of the present invention will be described in detail with reference to the drawings. Fig. 1 is a perspective view showing a medicinal liquid supplying device according to a first embodiment of the present invention in a state where it is attached to a toilet. Figs. 2 to 5 show the medicinal liquid supplying device according to the first embodiment of the present invention, with Fig. 2 being an upper perspective view, Fig. 3 being a lower perspective view, Fig. 4 being an exploded perspective view, and Fig. 5 being a vertical cross-sectional view. In the following description, the left-right direction of the toilet when the medicinal liquid supplying device is attached will be referred to as the left-right direction or lateral direction, the direction towards the toilet with respect to the medicinal liquid supplying device (the left direction in Fig. 5) will be referred to as the inward or inner side, and the opposite direction (the right direction in Fig. 5) will be referred to as the outward or outer side. Also, the depth direction of the toilet when the medicinal liquid supplying device is attached will be referred to as the depth direction.

[0026] As shown in Fig. 1, the chemical liquid dispenser 1 of this embodiment is used by attaching a replaceable chemical liquid container 40 filled with a chemical liquid including a cleaning agent, a disinfectant, or an air freshener. The chemical liquid dispenser 1 is attached to the rear side edge of the rim R of the toilet T, and supplies the chemical liquid filled in the chemical liquid container 40 into the bowl of the toilet T. The chemical liquid dispenser 1 is preferably attached to the rear side edge of the rim R of the toilet T so as not to get in the way of the user, but it can also be attached to another part of the rim R of the toilet T.

[0027] 1 to 5, the medicinal liquid supplying device 1 includes a fixing member 10 that can be attached to a toilet bowl, a housing 20 that is detachably attached to the fixing member 10, an opening member 30 that is fixed to the housing 20, and a tube 50 (FIG. 3). Also, FIGS. 1 to 5 show a state of use, and in the state of use, the medicinal liquid supplying device 1 further includes a medicinal liquid container 40 that is detachably attached to the housing 20.

[0028] Fig. 6 to Fig. 12 show the fixing member of the drug solution supplying device according to the first embodiment. Fig. 6 is a perspective view, Fig. 7 is a front view, Fig. 8 is a rear view, Fig. 9 is a vertical cross-sectional view seen from the front, Fig. 10 is a left side view seen from the inside, Fig. 11 is a vertical cross-sectional view seen from the left side, and Fig. 12 is a bottom view. Fixing member 10 is made of an elastically deformable material such as resin, and as shown in Figures 6 to 12, has fixing part 100 for attachment to the toilet bowl, and holding part 130 for holding housing 20 integrated with chemical solution container 40. In the attached state, fixing part 100 is located on the toilet bowl side, and holding part 130 is located on the outside of the toilet bowl.

[0029] The holding portion 130 has a housing fixing portion 140 and a chemical solution receiving portion 150 . The housing fixing portion 140 has a bottom surface 141 , and an arc wall portion 142 and a flat wall portion 143 that are provided upright along the outer edge of the bottom surface 141 .

[0030] Bottom surface 141 is plate-like and formed into an annular shape in a plan view. The outer shape of bottom surface 141 is linear on the fixed part 100 side and arc-shaped in other parts. The inner diameter of bottom surface 141 has a shape corresponding to the outer shape, with the inside (fixed part 100 side) being linear and the other parts being arc-shaped. As shown in FIG. 8, inner portion 141A on the far side of bottom surface 141 is concave toward the top, and the height of this portion is approximately equal to the upper surface of recess 114 of inner arm 110.

[0031] The arc wall portion 142 is provided perpendicular to the bottom surface 141 along the arc-shaped portion of the outer edge of the bottom surface 141. The height of the arc wall portion 142 is lower than the height of the planar wall portion 143. Slits 142A extending in the circumferential direction are formed at positions of the arc wall portions 142 facing each other in the depth direction.

[0032] The planar wall portion 143 stands along the inner part of the outer edge of the bottom surface 141 and extends perpendicularly to the bottom surface 141. The planar wall portion 143 is substantially rectangular in a side view, with both edges parallel to each other. A pair of guide protrusions 144 are formed on both widthwise edges of the outer side (the surface on the right side in FIG. 7) of the planar wall portion 143. The guide protrusions 144 extend from the lower end of the planar wall portion 143 to a predetermined height. The outer surface of the guide protrusions 144 is formed flat. In the assembled state, the planar wall portion 143 functions as a cover that covers the cutout 202A of the planar portion 202 of the housing 20.

[0033] Chemical solution receiving section 150 has a pedestal section 160 and a receiving dish section 170 formed above pedestal section 160. The planar shape of pedestal section 160 is a shape that follows the inner edge of bottom surface 141 and protrudes upward. The position of the underside of holding section 130 that abuts against pedestal section 160 has an upwardly concave shape.

[0034] The receiving tray 170 has a bottom 171 and a side wall 172, and a through hole 171A is formed in the center, penetrating in the up-down direction. The bottom 171 has a rectangular planar shape with arc-shaped corners. The upper end of the through hole 171A opens in the center of the width of the bottom 171, and the bottom 171 is inclined toward the through hole 171A. The side wall 172 is erected on the periphery of the bottom 171 and extends vertically. A connecting tube 173 is provided on the lower surface of the bottom 171. The through hole 171A extends through the connecting tube 173 and opens at the lower end of the connecting tube 173.

[0035] The fixed part 100 has an inner arm 110 that abuts against the inside of the rim of the toilet bowl, and an outer arm 120 that abuts against the outside of the rim of the toilet bowl. The inner arm 110 and the outer arm 120 are elastically deformable.

[0036] In this embodiment, the inner arm 110 and the outer arm 120 are not particularly limited as long as they are elastically deformable, but typically, resin or metal can be used. For example, the inner arm 110 and the outer arm 120 can be preferably made of a synthetic resin such as polyethylene terephthalate, polypropylene, polyethylene, or acrylic.

[0037] The inner arm 110 has a base 111 extending inward from the inner lower end of the holding part 130, and an inner abutment part 112 extending downward from the tip of the base 111. The base 111 extends laterally (so as to be horizontal in the mounted state) so that its lower surface abuts on the upper surface of the rim in the mounted state. As shown in FIG. 11, the base 111 has a substantially triangular vertical cross section in the depth direction, with the lower surface being a flat surface and the upper surface being an inclined surface that slopes upward toward the rear side. The inner arm 110 is formed so that the lower surface of the base 111 is flush with the lower surface of the housing fixing part 140 of the holding part 130.

[0038] 7, the inner surface of connection portion 113 between base portion 111 and inner contact portion 112 is curved in an arc shape so as to be convex upward and inward when viewed from the front. That is, the inner surface of base portion 111 and inner contact portion 112 are curved with a continuous curvature.

[0039] The inner contact portion 112 extends downward so that its rear surface (the surface on the right side in FIG. 7) comes into contact with the rim when in the attached state. The inner contact portion 112 has a shape in which the width is formed wider at the front side (lower side in FIG. 12) in a horizontal cross section and narrows toward the rear side. The inner surface of the inner contact portion 112 (the surface on the left side in FIG. 7) is formed in a circular arc shape that is convex toward the inside in a horizontal cross section. As shown in FIG. 12, the outer surface of the inner contact portion 112 (the surface on the right side in FIG. 7) is inclined inward toward the front side.

[0040] A recess 114 is formed on the side surface on the far side of the inner arm 110. The recess 114 is formed continuously from the base end of the base 111 to the tip of the inner abutment portion 112, and is open to the side surface of the inner arm 110 and the lower end of the inner abutment portion 112.

[0041] The outer arm 120 has an inclined portion 121 extending from the underside of the base end of the base portion 111 of the inner arm 110, and an outer abutment portion 122 extending upward from the inclined portion 121. Note that in this embodiment, the outer arm 120 extends from the base portion 111 of the inner arm 110, but this is not limited thereto, and the outer arm 120 may be configured to extend from the underside of the holding portion 130. The inner arm 110 is formed by bending a plate-shaped member, and its vertical cross section in the inward and outward directions is constant in the depth direction.

[0042] The inclined portion 121 is plate-shaped and extends diagonally downward (to the lower left in FIG. 7) toward the inside. The inclined portion 121 is connected to the inner arm 110 via the connecting portion 123. The base end of the inclined portion 121 has a curved shape that convexly faces outward (to the lower right in FIG. 7). Furthermore, the connecting portion 123 is also curved and continues from the base end of the inclined portion 121. The inner surface of the connecting portion 123 has an arc shape that is continuous with the base end of the inclined portion 121 and the lower surface of the base portion 111 of the inner arm 110. Furthermore, in this embodiment, the curvature of the base end of the inclined portion 121 and the inner surface of the connecting portion 123 is continuous, and is approximately constant in this embodiment.

[0043] In addition, the base end of inclined portion 121 having an outwardly convex curved shape means that inclined portion 121 has a curved shape and that the base end of inclined portion 121 is located outward (to the right in Figure 7) with respect to a straight line connecting the base end of inclined portion 121 and the middle portion or tip.

[0044] The outer surface of the connecting portion 123 extends vertically downward with the lower surface of the holding portion 130 as a fulcrum, and is continuous with the outer surface of the inclined portion 121. In this embodiment, the curvature of the outer surface of the curved portion of the base end of the inclined portion 121 is continuous, and in this embodiment, is approximately constant.

[0045] The vertical cross-sectional shape of the outer contact portion 122 is a curved shape that is convex outward (to the right in FIG. 7) at the center, and extends upward from the tip of the inclined portion 121. The outer contact portion 122 is connected to the inclined portion 121 via a connecting portion 125.

[0046] When the outer contact portion 122 is biased outward, the connection portion 123 bends the inclined portion 121 outward (so that the angle between the base portion 111 and the inclined portion 121 becomes larger), and the connection portion 125 between the inclined portion 121 and the outer contact portion 122 bends so that the outer contact portion 122 approaches the inclined portion 121 (so that the angle between the inclined portion 121 and the outer contact portion 122 becomes smaller). This makes it possible to increase the distance between the outer contact portion 122 and the inner contact portion 112 while suppressing the change in the attitude of the outer contact portion 122. Furthermore, in this state where the outer contact portion 122 and the inner contact portion 112 are separated from each other, a restoring force is generated by the elastic force of the outer arm 120 such that the outer contact portion 122 moves toward the inner contact portion 112. According to this embodiment, since the base end and the connection portion 123 of the inclined portion 121 are curved, when the outer arm 120 is bent, the force acting on the base end and the connection portion 123 of the inclined portion 121 can be reduced, so that the distance between the outer abutment portion 122 and the inner abutment portion 112 can be easily increased and damage to the base end and the connection portion 123 of the inclined portion 121 can be prevented.

[0047] As shown in Fig. 12, the inner surface of the outer abutment portion 122 (the surface on the left side in Fig. 12) is approximately perpendicular to the extension direction of the outer arm 120 and the inner arm 110 in a plan view. In contrast, in a plan view, the abutment surface of the inner abutment portion 112 is inclined inward (to the left in Fig. 12) toward the rear (downward in Fig. 12) with respect to a direction perpendicular to the extension direction of the inner arm 110 (the front-to-rear direction of the toilet in the installed state). As a result, the abutment surface of the inner abutment portion 112 forms an angle with respect to the abutment surface of the outer abutment portion 122 such that it widens toward the rear. In this embodiment, the angle between the abutment surface of the outer abutment portion 122 and the abutment surface of the inner abutment portion 112 is 12 degrees.

[0048] The angle between the contact surface of the outer contact portion 122 and the contact surface of the inner contact portion 112 (the angle between the straight lines A and B) is preferably 5 to 20 degrees, and more preferably 10 to 15 degrees. The angle between the inner surface and the outer surface of the toilet rim is different. The drug solution dispenser 1 of this embodiment is attached to the edge of the rear side of the bowl of the toilet, and the width of the rim expands toward the rear in this part. In contrast, the contact surface of the outer contact portion 122 is inclined with respect to the contact surface of the inner contact portion 112, so that the contact surface of the outer contact portion 122 and the contact surface of the inner contact portion 112 can be attached so as to follow the inner and outer surfaces of the toilet. If the angle of the contact surface of the outer contact portion 122 with respect to the contact surface of the inner contact portion 112 is out of the above angle range, the adhesion of the outer contact portion 122 and the inner contact portion 112 to the rim will decrease.

[0049] In addition, by inclining the contact surface of the inner contact portion 112 as described above, when the drug solution supplying device 1 is attached to the toilet, the inner arm 110 and the outer arm 120 extend laterally with respect to the front-rear direction of the toilet. This makes it possible to prevent the housing 20 and the like from interfering with the toilet lid or the toilet seat during use. Note that, when the contact surface of the inner contact portion 112 is curved in the horizontal cross section as in this embodiment, the angle between the straight line connecting the front end and the rear end of the contact surface of the inner contact portion 112 and the contact surface of the outer contact portion 122 may be set to the angle between the contact surface of the outer contact portion 122 and the contact surface of the inner contact portion 112. The same applies to the contact surface of the outer contact portion 122.

[0050] In this embodiment, the width of the inner arm 110 is 25 mm. The width of the inner arm 110 is preferably 15 to 50 mm, more preferably 20 to 40 mm, even more preferably 20 to 35 mm, and most preferably 25 to 35 mm. In the present embodiment, the liquid medicine supplying device 1 holds the liquid medicine container 40 at a position higher than the fixing member 10, and the liquid medicine supplying device 1 is likely to tilt due to the weight of the liquid medicine container 40. In contrast, according to this embodiment, the width of the inner arm 110 is 22 to 50 mm, so that the contact width between the upper surface of the toilet rim and the inner arm 110 can be increased, and the liquid medicine supplying device 1 can be fixed in a stable state.

[0051] Tube 50 is a flexible tube made of, for example, silicone. One end of tube 50 is attached to connecting tube 173. Tube 50 extends inside recess 114 of inner arm 110, and the other end of tube 50 reaches the lower end of inner contact portion 112. Since recess 114 is provided on the far side of inner arm 110, urine splashes and the like can be prevented from accumulating in recess 114 during use.

[0052] Fig. 13 to Fig. 20 show a housing of the drug solution feeder according to the first embodiment. Fig. 13 is an upper perspective view, Fig. 14 is a lower perspective view, Fig. 15 is a front view, Fig. 16 is a right side view, Fig. 17 is a top view, Fig. 18 is an AA cross-sectional view in Fig. 17, Fig. 19 is a BB cross-sectional view in Fig. 17, and Fig. 20 is a CC cross-sectional perspective view in Fig. 17. As shown in FIGS. 13 to 20, the housing 20 is made of, for example, resin, and has a cylindrical portion 200, an annular bottom portion 210, a dripping portion 220, and a pair of supports 230 that support the dripping portion 220.

[0053] Cylindrical portion 200 has arc portion 201 having a horizontal cross section formed in a substantially arc shape, and flat portion 202 having a linear horizontal cross section formed between both ends of arc portion 201. The height of cylindrical portion 200 is set so that the height of the upper edge of cylindrical portion 200 and the height of the upper edge of the flat wall portion of fixing member 10 are substantially equal when cylindrical portion 200 is attached to fixing member 10. As shown in FIG. 1, the height of cylindrical portion 200 is set so that side wall surface 411 of drug solution container 400 is not positioned above the upper edge of housing 20 in the attached state, and only chamfered connection portion 417 of drug solution container 400 (i.e., portion 419 on the bottom side of connection portion 417 (including connection portion 417, see FIG. 30A )) protrudes upward.

[0054] The width of the flat portion 202 is approximately equal to the width of the flat wall portion 143 of the fixing member 10. A notch 202A that projects downward is formed at the upper end of the flat portion 202. The lower edge of the notch 202A is formed in an arc shape, and its width is wider than the width of an adult's finger.

[0055] Guide recesses 202B are formed on both sides of the lower part of the flat surface portion 202. The guide recesses 202B are concave toward the outside compared to the center of the flat surface portion 202. The guide recesses 202B extend with a constant width from the lower end to a predetermined height along both sides of the flat surface portion 202. The inner surface of the guide recesses 202B is formed flat.

[0056] The arc portion 201 has a tapered portion 201C with a slightly smaller diameter at its lower end, and the diameter of the remaining portion is constant regardless of height. The arc portion 201 has slits 201B extending vertically at equal intervals. Also, a notch 201A that projects downward is formed at the upper end of the outer side of the arc portion 201 (the right side in FIG. 15). This notch 201A is disposed at a position opposite to the notch 202A of the flat portion 202 across the center point of the arc portion 201 in plan view.

[0057] A pair of flaps 203 are formed at positions facing each other in the depth direction of the arc portion 201. The flap 203 is defined by forming a slit 203A at the lower end of the arc portion 201, which extends continuously from both sides and the upper part. Both sides of the flap 203 are linear, and the upper part is arc-shaped. An engaging protrusion 204 extending in the circumferential direction is formed on the outer surface of the flap 203. The longitudinal section of the engaging protrusion 204 is triangular in shape such that the protruding width decreases toward the bottom. By pressing the upper part of the flap 203 toward the inside of the cylindrical portion 200, the flap 203 can be bent inwardly with the lower end as the center. The circumferential length of the flap 203 along the surface of the housing 20 is 80 mm or more. This prevents an infant from simultaneously pressing the flaps 203, thereby preventing the infant from accidentally removing the housing 20. As described later, the flap 203 having the engaging protrusion 204 and the slit 142A of the fixing member 10 constitute a fixing means for fixing the fixing member 10 in a state in which the fixing member 10 holds the housing 20.

[0058] According to one aspect of the present invention, the fixing means is not particularly limited, but examples thereof include a flap having an engaging protrusion, which will be described later, and fixing via a slit in the fixing member, engagement via a screw, adhesive tape or a clip, etc. From the viewpoint of more reliably preventing an infant from accidentally removing the drug solution container, the fixing means is preferably a flap having an engaging protrusion and fixing via a slit in the fixing member or engagement via a screw, and more preferably a flap having an engaging protrusion and fixing via a slit in the fixing member.

[0059] The annular bottom 210 extends inward from the lower edge of the tubular portion 200 at a right angle to the tubular portion 200. The annular bottom 210 is formed in an annular shape so as to fit along the lower edge of the tubular portion 200. The inner edge of the annular bottom 210 is linear on the inside and sides, and arc-shaped on the outside.

[0060] The support parts 230 are erected in the form of plates extending in the vertical direction on the inner edge of the annular bottom part 210. The pair of support parts 230 are provided at positions facing each other in the inward and outward directions of the annular bottom part 210. The inner support part 230 is formed in the form of a plate extending parallel to the flat part 202. The outer support part 230 is formed in the form of a plate having an arc-shaped horizontal cross section.

[0061] The dripping portion 220 has a receiving portion 221 and a hanging piece 222 extending downward from the receiving portion 221. The receiving portion 221 has a bottom plate 223 formed in a square shape with rounded corners, and a cylindrical side plate 224 standing upward on the edge of the bottom plate 223. The shape of the bottom plate 223 is approximately the same as the shape of the outer frame portion 320 of the opening member 30. A pair of engagement portions 224A are formed on the inner surface of the side plate 224, which extend horizontally around the entire circumference at a predetermined interval in the vertical direction. A portion of the inner wall of the side plate 224 between the pair of engagement portions 224A is recessed outward. The opening member 30 is disposed in the upper portion of the space defined by the bottom plate 223 and the side plate 224 of the receiving portion 221, as described later.

[0062] Further, in the center of the bottom plate 223 of the receiving portion 221, there are provided a cylindrical guide tube 225 that fits into the fixed tube 340 of the opening member 30, and a circular fixed wall 226 that is provided so as to surround the periphery of the guide tube 225. The gap between the guide tube 225 and the fixed wall 226 is dimensioned so that the fixed tube 340 fits into it. The guide tube 225 is cylindrical, and its upper end opens forward (to the left in FIG. 19), inclining downward. As shown in FIG. 20, a guide groove 227 extending in the vertical direction is formed in the front of the outer surface of the guide tube 225.

[0063] An opening 228A (FIGS. 14 and 20) is formed on the inside of fixed wall 226, penetrating bottom plate 223 from top to bottom. The upper surface of hanging piece 222 is exposed in opening 228A, and guide pipe 225 is erected on the upper surface of hanging piece 222. Between guide pipe 225 and fixed wall 226, the front and rear of guide pipe 225 are closed by hanging piece 222, and the parts other than the front and rear (inner and outer parts) are connected to the upper and lower sections of bottom plate 223 through opening 228A. The inside of guide pipe 225 is closed by bottom plate 223.

[0064] A hanging piece 222 hangs down from the lower surface of bottom plate 223. Hanging piece 222 is formed in a plate shape and has a predetermined width in the depth direction. The inner and outer surfaces of hanging piece 222 are formed along the edges of inner and outer openings 228A, respectively. Guide grooves 222A extending in the up-down direction are formed on the surfaces of the inner and outer surfaces of hanging piece 222.

[0065] Figures 21 to 24 show the opening member of the drug solution supplying device according to the first embodiment, in which Figure 21 is a perspective view, Figure 22 is a right side view, Figure 23 is a vertical cross-sectional view as seen from the right side, and Figure 24 is a vertical cross-sectional view as seen from the front. As shown in Figures 21 to 23, the opening member 30 is made of, for example, resin, and has a substrate 310, an outer frame portion 320 surrounding the edge of the substrate 310, an opening tube 330 standing on the upper surface of the substrate 310, and a fixed tube 340 standing on the lower surface of the substrate 310.

[0066] The substrate 310 is formed as a circular flat plate. The substrate 310 extends to the inner region of the open cylinder 330, and the end of the open cylinder 330 is open in the center.

[0067] As shown in Figure 23, the outer frame portion 320 has an inner tube portion 321 that is erected upward from the outer edge of the substrate 310, an upper surface portion 322 that is connected to the outer periphery of the upper edge of the inner tube portion 321, and an outer tube portion 323 that is erected downward from the outer edge of the upper surface portion 322.

[0068] The inner cylinder portion 321 is formed in a cylindrical shape. The upper surface portion 322 is plate-shaped, with the inner edge formed in a circular shape corresponding to the inner cylinder portion 321, and the outer edge formed in a square shape with the corners chamfered in an arc shape. The outer cylinder portion 323 is tubular corresponding to the outer edge shape of the upper surface portion 322. The outer cylinder portion 323 extends below the substrate 310. The outer cylinder portion 323 is divided by a groove extending in the circumferential direction into an upper portion 323A that extends from the connection portion with the upper surface portion 322 to a predetermined height, and a lower portion 323B that is lower than the predetermined height.

[0069] The open cylinder 330 is vertically disposed at the center of the substrate 310. The open cylinder 330 is cylindrical, and the upper edge is inclined so that one side is higher.

[0070] The fixed cylinder 340 is formed in a cylindrical shape and is vertically disposed at the center of the substrate 310. The inner diameter of the fixed cylinder 340 is approximately equal to the outer diameter of the guide tube 225, and the outer diameter of the fixed cylinder 340 is approximately equal to the inner diameter of the fixed wall 226. The internal space of the fixed cylinder 340 and the internal space of the open cylinder 330 are in communication with each other.

[0071] 25 to 27 are diagrams showing a liquid medicine container of the liquid medicine supplying device according to the first embodiment. FIG. 25 is a left side view, FIG. 26 is a plan view, and FIG. 27 is a vertical cross-sectional view seen from the front. As shown in FIGS. 25 to 27, liquid medicine container 40 is made of resin, which will be described later. Liquid medicine container 40 includes bottle portion 410 made of transparent or semi-transparent resin, and sealing cap 420. Bottle portion 410 has a horizontal cross-sectional shape with side wall surface 411, bottom surface 415, and top surface 416. Connection portion 417 between bottom surface 415 and side wall surface 411, and connection portion 418 between side wall surface 411 and top surface 416 are chamfered. Side wall surface 411 of bottle portion 410 includes linear flat portion 412 and arc-shaped portion 413 in horizontal cross-sectional view. The plane portion 412 of the side wall surface 411 is formed as a flat surface, and the arc-shaped portion 413 is formed as a part of a cylindrical shape. A discharge port 414 is formed in a top surface 416 of the bottle portion 410.

[0072] The sealing cap 420 comprises a cylindrical portion 421 and a membrane member 422 provided to close one end of the cylindrical portion 421. The membrane member 422 is made of an easily penetrable material such as aluminum foil. The sealing cap 420 is fixed to the outlet 414 of the bottle portion 410, and the outlet 414 of the bottle portion 410 is sealed by the membrane member 422.

[0073] Bottle portion 410 of liquid medicine container 40 is filled with liquid medicine. Before use, outlet 414 is sealed by membrane member 422. When in use, membrane member 422 is opened, allowing the liquid medicine in bottle portion 410 to flow out through outlet 414.

[0074] In this embodiment, the bottle portion 410 of the liquid medicine container 40 is made of a transparent or semi-transparent resin, but the entire liquid medicine container 40 may be made of a transparent or semi-transparent resin. However, it is preferable that the portion of the cutout 202A is transparent or semi-transparent so that the content amount can be confirmed through the cutout 202A.

[0075] In this embodiment, the material constituting the liquid medicine container 40 is not particularly limited, but typically, a hard resin or metal can be used. For example, the liquid medicine container 40 can be preferably made of a synthetic resin such as polyethylene terephthalate, polyethylene, or polypropylene. The fixing member and the housing are also made of the same material.

[0076] In the assembled state, the opening member 30 is fixed to the housing 20. FIG. 28 is an enlarged cross-sectional view showing the structure of the connection part between the opening member and the housing in the assembled state. In the assembled state, the outer tube part 323 of the opening member 30 is placed in the side plate 224 of the dripping part 220. Then, the upper part 323A of the outer tube part 323 enters the recess between the engagement parts 224A, and the upper part 323A of the outer tube part 323 abuts against the upper and lower engagement parts 224A, respectively, thereby fixing the opening member 30 to the dripping part 220. At the same time, the fixed tube 340 is fitted between the guide tube 225 and the fixed wall 226. As a result, the opening member 30 is integrated with the housing 20.

[0077] In addition, since guide tube 225 is located inside fixed barrel 340 in the fitted state, a passage (guide path) for the drug solution is defined by the inner wall surface of fixed barrel 340 and guide groove 227. A space through which the drug solution passes is also formed in the gap between guide tube 225 and fixed wall 226 of bottom plate 223 and the gap between the lower end of fixed barrel 340. As a result, a flow path is formed that leads from the space inside inner barrel portion 321 of opening member 30 through guide groove 227 and the gap between the lower end of fixed barrel 340 and bottom plate 223 to opening 228A.

[0078] The liquid medicine container 40 is attached to the housing 20. The liquid medicine container 40 is attached to the housing 20 by aligning the bottle part 410 so that the discharge port 414 of the bottle part 410 faces the housing 20 and the flat part 412 of the bottle part 410 is aligned along the flat part 202 of the housing 20, and pushing the bottle part 410 toward the housing 20. As a result, the bottle part 410 is held in the housing 20 with the side wall surface 411 of the bottle part 410 surrounded by the cylindrical part 200 of the housing 20. Furthermore, when the bottle part 410 is pushed into the housing 20, the opening cylinder 330 of the opening member 30 opens the membrane member 422 of the liquid medicine container 40. In this manner, when the bottle part 410 is accommodated in the housing 20, the opposing parts of the bottle part 410 are exposed to the outside at the cutouts 201A and 202A of the cylindrical part 200 of the housing 20. Furthermore, when bottle portion 410 is accommodated within housing 20, only the portion of bottle portion 410 closer to bottom surface 415 than connection portion 417 protrudes from housing 20, thereby preventing the liquid medicine container 40 from being removed from housing 20 by grabbing the portion of liquid medicine container 40 protruding from the end of housing 20.

[0079] The fixing member 10 is attached to the rim R of the toilet. FIG. 29 is a diagram showing the state in which the fixing member is attached to the rim of the toilet. As shown in FIG. 29, when attaching the fixing member 10, a force is applied to the outer abutment portion 122 and the inner abutment portion 112 so as to separate them. In this state, the lower surface of the base portion 111 of the inner arm 110 is abutted against the upper surface of the rim of the toilet, and the force acting on the outer abutment portion 122 and the inner abutment portion 112 is released. As a result, a restoring force of the fixing member 10 is generated, and the outer surface of the inner abutment portion 112 abuts against the inner surface of the rim, and the inner surface of the outer abutment portion 122 abuts against the outer surface of the rim. Then, the fixing member 10 can be attached to the rim by sandwiching the rim between the outer abutment portion 122 and the inner abutment portion 112. In addition, when attached to the rim, the tip of the inner abutment portion 112 of the inner arm 110 is located in the bowl of the toilet, and the tip of the tube 50 is located in the toilet.

[0080] The housing 20 is attached to the fixed member 10 with the bottle portion 410 housed therein. When attaching the housing 20 to the fixed member 10, the housing 20 is aligned so that the outer surface of the flat portion 202 of the housing 20 abuts against the flat wall portion 143 of the fixed member 10 and the guide protrusion 144 of the fixed member is positioned within the guide recess 202B of the housing 20. Then, the housing 20 is pushed toward the fixed member 10. When the housing 20 is pushed in, the lower end of the engagement protrusion 204 abuts against the upper edge of the arc wall portion 142, and the flap 203 is bent inward. When the housing 20 is further pushed in, the engagement protrusion 204 enters the slit 142A of the arc wall portion 142, and the flap 203 is restored to its original state. As a result, the upper surface of engaging protrusion 204 of flap 203 engages with flap 203, and housing 20 is held by fixing member 10 with the lower part of tubular portion 200 of housing 20 accommodated within housing fixing portion 140 of fixing member 10. With housing 20 attached to fixing member 10, notch 202A of flat portion 202 of housing 20 is covered by flat wall portion 143, and the side surface of drug solution container 40 exposed through notch 202A is also covered by flat wall portion 143.

[0081] In this state, the medicinal liquid filled in the medicinal liquid container 40 flows into the open tube 330 that penetrates the membrane member 422. The medicinal liquid that has flowed into the open tube 330 passes through the guide groove 227 and the gap between the lower end of the fixed tube 340 and the bottom plate 223, and flows into the opening 228A. The medicinal liquid that has flowed into the opening 228A descends along the wall surface of the hanging piece 222 and drips into the receiving tray 170 of the fixed member 10. The medicinal liquid that has dripped into the receiving tray 170 flows into the tube 50 through the through hole 171A, and drips through the tube 50 into the toilet bowl.

[0082] In this embodiment, the medicinal liquid filled in the medicinal liquid container 40 is not particularly limited, but contains one or more components selected from a group including a cleaning agent, a disinfectant, a deodorant, and an aromatic, and may also contain a coloring agent. The medicinal liquid is mixed with flushing water to provide the effects of the components contained in the medicinal liquid to the inside of the toilet bowl or the inside of the toilet room. For example, if the medicinal liquid contains a cleaning agent and a disinfectant, it can clean and disinfect the toilet bowl, and if it contains a deodorant and an aromatic, it can eliminate unpleasant odors and fill the toilet room with a pleasant fragrance.

[0083] Next, a method for replacing the drug solution container 40 will be described. First, the liquid medicine container 40 is removed. FIG. 30 is a diagram for explaining a method for removing the liquid medicine container. As shown in FIG. 30(A), the pair of flaps 203 of the housing 20 are simultaneously pushed in. As a result, the engaging protrusion 204 moves inward and is released from the slit 142A of the arc wall portion 142. Then, as shown in FIG. 30(B), the housing 20 is pulled out from the fixing member 10 with the pair of flaps 203 pushed in like this. Next, as shown in FIG. 30(C), the housing 20 with the liquid medicine container 40 attached thereto is rotated so that the discharge port 414 of the liquid medicine container 40 faces upward. Next, as shown in FIG. 30(D), the side wall surface 411 of the liquid medicine container 40 exposed from the notches 201A and 202A is pinched with fingers. In this state, the liquid medicine container 40 is pulled out from the housing 20. This allows the liquid medicine container 40 to be removed.

[0084] Next, a new liquid medicine container is attached. First, the bottle part 410 is aligned so that the discharge port 414 of the bottle part 410 faces the housing 20 and the flat surface part 412 of the bottle part 410 is aligned along the flat surface part 202 of the housing 20, and the bottle part 410 is pushed toward the housing 20. At this time, the opening tube 330 of the opening member 30 opens the membrane member 422 of the sealing cap 420 of the liquid medicine container 40.

[0085] Next, the housing 20 is aligned so that the outer surface of the flat portion 202 of the housing 20 abuts against the flat wall portion 143 of the fixed member 10 and the guide protrusion 144 of the fixed member is positioned within the guide recess 202B of the housing 20. Then, the housing 20 is pushed toward the fixed member 10 so that the engagement protrusion 204 enters the slit 142A of the arc wall portion 142. This allows the housing 20 to be attached to the fixed member 10.

[0086] As described above, the first embodiment provides the following advantages. According to the first embodiment, the medicinal liquid supplying device 1 can be attached to the toilet bowl in a stable state because the edge of the toilet bowl is sandwiched between the inner abutment portion 112 of the inner arm 110 and the outer abutment portion 122 of the outer arm 120. Furthermore, because the base end portion of the inclined portion 121 has an outwardly convex curved shape, the outer arm 120 can be significantly bent outward, and the medicinal liquid supplying device 1 can be attached to the toilet bowl regardless of the width of the edge of the toilet bowl.

[0087] Furthermore, according to the first embodiment, the connection portion 123 of the inclined portion 121 to the inner arm 110 is formed in a curved shape that is continuous with the base end portion of the inclined portion 121. This makes it possible to prevent a large load from acting locally on the connection portion 123 when the outer arm 120 is deformed, and to prevent the outer arm 120 from being damaged.

[0088] Also, according to the first embodiment, the contact surface of the inner contact portion 112 is angled relative to the contact surface of the outer contact portion 122 so as to widen towards the rear of the toilet. When mounting the medicinal liquid supplying device, it is preferable to mount it on the edge of the rear side of the toilet bowl so as not to hinder the user, and in such a portion the rim width widens towards the rear. In contrast, according to the first embodiment, the contact surface of the inner contact portion 112 is angled relative to the contact surface of the outer contact portion 122 so as to widen towards the rear, so that the medicinal liquid supplying device 1 can be stably mounted to the edge of the toilet.

[0089] Also, according to the first embodiment, the contact surface of the inner contact portion 112 is inclined inward toward the rear with respect to a direction perpendicular to the extension direction of the inner arm 110. As described above, when installing the medicinal liquid supplying device, it is preferable to install it on the edge of the rear side of the toilet bowl, and in such a portion, the inner surface of the rim is inclined inward toward the rear. In contrast, according to the first embodiment, the contact surface of the inner contact portion 112 is inclined inward toward the rear with respect to a direction perpendicular to the extension direction of the inner arm 110, so that the inner arm 110 extends inward and outward, and the medicinal liquid container 40 is prevented from interfering with the lid or the toilet seat.

[0090] Furthermore, according to the first embodiment, the cross section of the outer contact portion 122 is formed into an outwardly convex curved shape. The cross section of the outer surface of the toilet is also curved and outwardly convex. In contrast, according to the first embodiment, the outer contact portion 122 can be made to contact the outer surface of the toilet so as to fit along the surface.

[0091] Furthermore, according to the first embodiment, inner arm 110 includes base 111 extending from holding portion 130, inner abutment portion 112 extends from base 111, and base 111 has a width of 15 mm to 50 mm. As a result, the base abuts against the edge of the rim of the toilet over a wide area, the medicinal liquid supply device can be stably attached to the edge of the toilet.

[0092] Furthermore, according to the first embodiment, the toilet includes a tube 50 that discharges the chemical solution supplied from the chemical solution container 40 into the bowl, and the tube 50 extends inside a recess 114 formed in the rear side surface of the inner arm 110. As a result, the recess 114 that houses the tube 50 faces rearward, so that when a person urinates in the toilet, dirt can be prevented from accumulating inside the recess 114.

[0093] A second embodiment of the present invention will be described below. The drug solution supplying device according to the second embodiment differs from the first embodiment in the shape of the fixing part of the fixing member. In the following description, the same structures as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted.

[0094] Figures 31 to 33 are views showing the configuration of a fixing member according to a second embodiment. Figure 31 is a front view, Figure 32 is a perspective view seen from the upper left of the front, and Figure 33 is a perspective view seen from the upper right of the rear. As shown in Figures 31 to 33, a fixing member 60 according to the second embodiment is made of an elastically deformable material such as resin, and has a fixing part 500 for attaching to the toilet bowl and a holding part 130 for holding the housing 20.

[0095] The fixing part 500 has an inner arm 510 that abuts against the inside of the toilet rim and an outer arm 520 that abuts against the outside of the toilet rim.

[0096] The inner arm 510 has a base 511 extending inward from the inner lower end of the holding part 130, and an inner abutment part 512 extending downward from the tip of the base 511. The base 511 extends laterally so that its lower surface abuts against the upper surface of the rim in the attached state. The base 511 has a substantially triangular vertical cross section in the depth direction, with the lower surface being a flat surface and the upper surface being an inclined surface that slopes upward toward the back side. The inner arm 510 is formed so that the lower surface of the base 511 is flush with the lower surface of the housing fixing part 140 of the holding part 130.

[0097] A connection portion 513 between the base portion 511 and the inner contact portion 512 is curved in an arc shape so as to be convex upward and inward in front view.

[0098] The inner contact portion 512 extends downward so that its outer surface comes into contact with the inner surface of the rim when the inner contact portion 512 is attached. In a horizontal cross section, the inner surface of the inner contact portion 512 is formed in an arc shape that is convex toward the inside (toward the left side in FIG. 31).

[0099] A recess 514 is formed on the side surface on the far side of the inner arm 510. The recess 514 is formed continuously from the base end of the base 511 to the tip of the inner abutment portion 512, and is open to the side surface of the inner arm 510 and the lower end of the inner abutment portion 512.

[0100] The outer arm 520 has an inclined portion 521 extending from the underside of the base end of the base portion 511 of the inner arm 510, and an outer abutment portion 522 extending upward from the inclined portion 521. Note that in this embodiment, the outer arm 520 extends from the base portion 511 of the inner arm 510, but this is not limited thereto, and the outer arm 520 may be configured to extend from the underside of the holding portion 130. The inner arm 510 is formed by bending a plate-like member, and its vertical cross section in the inward and outward directions is constant in the depth direction.

[0101] The inclined portion 521 is plate-shaped and extends diagonally downward toward the inside (to the lower left in FIG. 31).

[0102] The base end of inclined portion 521 has a curved shape that convexly extends outward (to the lower right in FIG. 31). Furthermore, connecting portion 523 also has a curved shape that is continuous with the base end of inclined portion 521. The inner surface of connecting portion 523 has an arc shape that is continuous with the base end of inclined portion 521 and the lower surface of base portion 511 of inner arm 510. In this embodiment, the curvature of the base end of inclined portion 521 and the inner surface of connecting portion 523 is continuous, and is approximately constant in this embodiment.

[0103] Further, the tip of the inclined portion 521 on the side of the outer contact portion 522 has a curved shape that is convex inward (toward the upper left in FIG. 31), so that the inclined portion 521 has an overall S-shape in side view.

[0104] The outer contact portion 522 extends upward from the tip of the inclined portion 521. The outer contact portion 522 is connected to the inclined portion 521 via a connecting portion 525.

[0105] When the outer contact portion 522 is biased outward, the connection portion 523 bends in a direction in which the inclined portion 521 faces downward (so that the angle between the base portion 511 and the inclined portion 521 becomes larger), and the connection portion 525 between the inclined portion 521 and the outer contact portion 522 bends so that the outer contact portion 522 approaches the inclined portion 521 (so that the angle between the inclined portion 521 and the outer contact portion 522 becomes smaller). This makes it possible to increase the distance between the outer contact portion 522 and the inner contact portion 512 while suppressing the change in the posture of the outer contact portion 522. Furthermore, in this state in which the outer contact portion 522 and the inner contact portion 512 are separated from each other, a restoring force is generated by the elastic force of the outer arm 520 such that the outer contact portion 522 moves toward the inner contact portion 512. According to this embodiment, the base end and the connecting portion 523 of the inclined portion 521 have an outwardly convex curved shape, so that when the outer arm 520 is bent, the force acting on the base end and the connecting portion 523 of the inclined portion 521 can be reduced, the distance between the outer abutment portion 522 and the inner abutment portion 512 can be easily increased, and the base end and the connecting portion 523 of the inclined portion 521 can be prevented from being damaged.

[0106] Furthermore, according to this embodiment, the tip portion connected to the outer abutment portion 522 of the inclined portion 521 has an inwardly convex curved shape, so that when the outer arm 520 is bent, the force acting on the tip portion and connection portion 525 of the inclined portion 521 can be reduced, the distance between the outer abutment portion 522 and the inner abutment portion 512 can be easily increased, and damage to the tip portion and connection portion 525 of the inclined portion 521 can be prevented.

[0107] According to the second embodiment, the following effects are achieved in addition to those achieved in the first embodiment. According to the second embodiment, the tip of the inclined portion 121 on the connection side to the outer abutment portion 122 is formed in an inwardly convex curved shape. This allows the outer abutment portion 122 to be largely deflected relative to the inclined portion 121, and the drug solution supplying device 1 can be attached to the toilet bowl even if the edge width is wider.
