Description

The present invention relates to a chemical liquid supplying device that supplies chemical liquids for fragrance, deodorization, cleaning, etc. to the outside, and is, for example, a chemical liquid supplying device that is installed in a dish-shaped hand washing section provided on top of a water storage tank of a flush toilet and supplies chemical liquids to running water (flush water) for flushing.

Flush toilets have traditionally used on-tank chemical supply devices that are installed in the hand washing section above the water tank to supply chemicals, for example for fragrance, deodorization, and cleaning, to the running water used for flushing (flush water).

One known example of this on-tank type drug supply device is one that includes a drug container that contains the drug solution, a cup-shaped support that supports the drug container from below with the drug solution outlet facing downward, and has multiple long legs and a guide member protruding from the bottom of the support that are inserted into the drain of the hand-washing section (see, for example, Patent Document 1). In this drug supply device, the drug solution is discharged from the outlet of the drug solution container onto the support, and the drug solution discharged onto the support is guided and held by the guide member. Then, as running water is supplied to the hand-washing section from a water-discharging tap located above the hand-washing section and flows toward the drain, it sweeps up the drug solution on the guide member, so that it flows from the drain together with the running water into the water tank.

In addition, in flush toilets, the hand washing area is sometimes decorated with artificial flowers, ornaments, and other decorations to improve the aesthetic appearance of the toilet.

However, in order to decorate the washbasin in which the liquid medicine supply device is installed with the above-mentioned decorations, a large space is required in the washbasin. Furthermore, the decorations may block the various openings formed in the liquid medicine supply device or the drain in the washbasin, which may result in problems such as not being able to achieve the desired effect of the liquid medicine supply device or water clogging. Such problems may also occur with liquid medicine supply devices other than the on-tank type.

The present invention has been made to solve the above problems, and aims to provide a liquid medicine supplying device that has an aesthetic appearance. It also aims to provide a liquid medicine supplying device in which the discharge of the liquid medicine from the discharge port is not hindered by decorations contained in the liquid medicine container.

The liquid medicine supply device of the present invention comprises a liquid medicine container whose interior can be seen, a liquid medicine contained in the liquid medicine container, a support that supports the liquid medicine container from below with the liquid medicine outlet facing downward, and a decorative object that is contained in the liquid medicine container together with the liquid medicine, and is characterized in that the liquid medicine container has at least one guide groove recessed on the inner surface outside the outlet, with a portion of the guide groove connected to the outlet and guiding the liquid medicine to the outlet.

In the drug supply device of the present invention, it is preferable that the guide grooves are provided in a radial manner around the discharge port.

In addition, in the drug solution supply device of the present invention, it is preferable that the guide groove is provided in a ring shape so as to surround the discharge port.

According to the present invention, a decoration is contained inside a liquid medicine container whose interior is visible, together with the liquid medicine, and the decorative effect of the decoration gives the liquid medicine supply device itself a beautiful appearance, eliminating the need for other decorations. Therefore, for example, when the liquid medicine supply device is installed in the hand-washing section above the water tank of a flush toilet, it is sufficient to secure a space the same as that of a conventional liquid medicine supply device, and a large space in the hand-washing section is not required for decoration. Furthermore, since the various openings formed in the liquid medicine supply device and the drain in the hand-washing section are not blocked, the desired effect of the liquid medicine supply device can be obtained.

In addition, at least one guide groove is recessed on the inner surface of the liquid medicine container, outside the discharge outlet, with a portion of the guide groove connected to the discharge outlet to guide the liquid medicine to the discharge outlet. Therefore, even if the decoration inside the liquid medicine container covers and blocks the discharge outlet, the liquid medicine inside the liquid medicine container is discharged from the discharge outlet through the guide groove to the outside of the liquid medicine container. Therefore, the discharge of the liquid medicine from the discharge outlet is not hindered by the decoration inside the liquid medicine container, and the liquid medicine can be supplied without any problems.

The actual form of the present invention will be described below with reference to the attached drawings. Figs. 1 to 3 show the external configuration of a medicinal liquid supplying device 1 according to one embodiment of the present invention. Note that the medicinal liquid supplying device 1 of this embodiment is an example of a type that is installed in a dish-shaped hand washing section provided above the water storage tank of a flush toilet.

The medicinal liquid supplying device 1 comprises a medicinal liquid, for example for fragrance/deodorizing the space within the toilet or for flushing the toilet bowl, a medicinal liquid container 2 for containing the medicinal liquid, a support 3 to which the medicinal liquid container 2 is detachably attached, and a decorative object 7 contained in the medicinal liquid container 2 together with the medicinal liquid. The medicinal liquid supplying device 1 is installed in the hand-washing section such that the guide member 5 and the long legs 32 protruding from the bottom surface portion 30 of the support 3 are inserted into the drain of the hand-washing section. Each component of the medicinal liquid supplying device 1 will be described below.

As shown in Figures 3 to 6, the liquid medicine container 2 has a body 20 capable of containing the liquid medicine, and a cylindrical mouth 21 that is integrally formed and continuous with the body 20. Note that when in use, the liquid medicine container 2 is attached to the support 3 upside down with the mouth 21 facing downwards, so in the following description, the mouth 21 side of the liquid medicine container 2 is referred to as the "lower side" and the body 20 side as the "upper side."

The inside of the liquid medicine container 2 can be seen from the outside, and can be made visible, for example, by making the entire container transparent or translucent. The inside can also be made visible by making at least a portion of the liquid medicine container 2 transparent or translucent. The body 20 and the mouth 21 of the liquid medicine container 2 can be made of, for example, glass or synthetic resin.

A discharge port 22 is opened at the bottom of the body 20, which communicates with the mouth 21 and is used to discharge the liquid medicine inside the body 20. A cap 23 is detachably placed on the mouth 21. The cap 23 can be made of, for example, a soft synthetic resin. The cap 23 has a blocking portion 24 with a thin portion 25 interposed therebetween at the portion that blocks the mouth 21.

As shown in Figures 5 and 6, guide grooves 26 are recessed on the inner surface of the body 20 outside the discharge port 22. The guide grooves 26 are formed by recessing a part of the inner surface of the body 20, and a part of the guide grooves 26 is connected to the discharge port 22. In this embodiment, the guide grooves 26 are provided radially from the discharge port 22 as the center, with one end connected to the discharge port 22, and are arranged at equal intervals around the discharge port 22.

As shown in FIG. 7, the guide groove 26 serves to guide the liquid medicine in the liquid medicine container 2 to the outlet 22 when the decoration 7 contained inside the liquid medicine container 2 is present at the bottom (lower part) of the liquid medicine container 2 and covers the outlet 22. If the decoration 7 in the liquid medicine container 2 covers the outlet 22, the outlet 22 may be blocked and the decoration 7 may prevent the liquid medicine from being discharged from the outlet 22. However, even in this case, the liquid medicine flows along the guide groove 26 to the outlet 22, allowing the liquid medicine in the liquid medicine container 2 to be discharged smoothly from the outlet 22.

The liquid medicine container 2 is used upside down with the cap 23 attached to the mouth 21 and the cap 23 (the discharge port 22 of the body 20) facing downward. When in use, the liquid medicine container 2 and the support 3 are connected by inserting the cylindrical connecting member 44 of the support 3, which will be described later, into the mouth 21 of the liquid medicine container 2 so as to break through the closing portion 24 of the cap 23. This allows the liquid medicine in the liquid medicine container 2 to pass from the discharge port 22 through the mouth 21 and be discharged into the support 3 via the connecting member 44. The connecting member 44 of the support 3 fits into the mouth 21 of the liquid medicine container 2, making it difficult for the connecting member 44 to come out of the mouth 21.

One or more streak-like bends 8 are formed on the circumferential surface of the drug solution container 2 when viewed from the front and/or rear. The streak-like bends 8 are formed in a convex shape such that the circumferential surface of the body 20 protrudes outward in a V shape, or in a concave shape such that the circumferential surface of the body 20 recesses inward in a V shape, and the circumferential surface of the body 20 has an angular shape at the streak-like bends 8. In this embodiment, the streak-like bends 8 are formed in a convex shape.

The streak-like bends 8 may extend in any direction, up and down, left and right, or diagonally. The streak-like bends 8 may extend in a straight line or in a curved line. The streak-like bends 8 may be formed only on either the front side or the back side of the circumferential surface of the body 20, but it is preferable that they are formed on both the front side and the back side of the circumferential surface of the body 20, and it is further preferable that the streak-like bends 8 on the front side and the back side of the circumferential surface of the body 20 are formed around the circumference in a circumferential direction so that they are connected to each other. In this embodiment, multiple (3) streak-like bends 8 are formed around the circumference in a circumferential direction of the circumferential surface of the body 20, with the top and bottom positions being different from each other.

The position where the streak-like bends 8 are formed on the circumferential surface of the drug solution container 2 is not particularly limited, but it is preferable that at least a part of the streak-like bends 8 is formed in the central region in the height direction of the drug solution container 2. Note that the central region in the height direction of the drug solution container 2 refers to the region from H/3 to 2H/3 from the bottom end of the body 20, based on the height H of the body 20 of the drug solution container 2.

By forming the striated bends 8 on the peripheral surface of the liquid medicine container 2, as shown in FIG. 8, the decoration 7 inside the liquid medicine container 2 appears blurred, large, or refracted due to light refraction in the areas where the striated bends 8 are formed. On the other hand, if the striated bends 8 are not formed on the peripheral surface of the liquid medicine container 2, as shown in FIG. 9, the decoration 7 inside the liquid medicine container 2 is clearly visible. In this way, by forming the striated bends 8 on the peripheral surface of the liquid medicine container 2, the decoration 7 inside the liquid medicine container 2 is not clearly visible, making it possible to express an abstract design, and depending on the shape of the decoration 7, the decorative effect of the decoration 7 can be increased.

In addition, since the striated bends 8 are formed around the entire circumference of the peripheral surface of the liquid medicine container 2, the decoration 7 inside the liquid medicine container 2 can be expressed in the above-mentioned abstract design no matter where the liquid medicine container 2 is viewed from. Furthermore, since the liquid medicine supply device 1 of this embodiment is generally installed at eye level, the liquid medicine supply device 1 is often viewed straight on, but since the striated bends 8 are formed in the central region in the height direction of the liquid medicine container 2, the decoration 7 inside the liquid medicine container 2 can be effectively expressed in the above-mentioned abstract design.

One or more three-dimensional patterns 9 are formed on the periphery of the drug solution container 2 when viewed from the front and/or the back. The three-dimensional pattern 9 is composed of convex portions formed by protruding a part of the periphery of the body 20 outward, and/or concave portions formed by recessing a part of the periphery of the body 20 inward. In this embodiment, the three-dimensional pattern 9 having one desired design as a whole is formed by combining multiple convex portions and concave portions, but the three-dimensional pattern 9 may also be formed by each convex portion and each concave portion having a desired design.

The three-dimensional pattern 9 may be formed only on either the front or back side of the circumferential surface of the body 20, but is preferably formed on both the front and back sides of the circumferential surface of the body 20. In addition, the position where the three-dimensional pattern 9 is formed on the circumferential surface of the drug solution container 2 is not particularly limited, but it is preferably positioned in the center in the left-right direction on the front or back side of the circumferential surface of the body 20.

By forming the three-dimensional pattern 9 on the peripheral surface of the liquid medicine container 2, the decoration 7 inside the liquid medicine container 2 cannot be seen clearly in the part where the three-dimensional pattern 9 is formed due to refraction of light, just like the part where the streak-like bends 8 are formed, making it possible to express an abstract design. Therefore, depending on the shape of the decoration 7, the decorative effect of the decoration 7 can be increased.

Next, as shown in Figs. 1 to 3 and 10 to 13, the support 3 is formed in a cup shape with an open top, and supports the connected drug solution container 2 from below. The support 3 includes a bottom surface portion 30, a side surface portion 31, a cover member 4, and a guide member 5. Like the drug solution container 2, the support 3 has a horizontally elongated outer shape in a plan view in which the length in a first direction (left-right direction in Fig. 1) is longer than the length in a second direction (left-right direction in Fig. 2) perpendicular thereto. In this embodiment, the support 3 is formed in a substantially elliptical shape in a plan view. When the hand-washing section has a horizontally elongated shape, the drug solution supplying device 1 is installed so that the first direction (left-right direction of the support 3 and the drug solution container 2) coincides with the left-right direction of the hand-washing section. The support 3 can be formed of a synthetic resin such as polyethylene, polypropylene, or polyethylene terephthalate, and is flexible.

The bottom surface portion 30 is provided with a number of long legs 32 (two in the illustrated example) that protrude downward. In addition, a number of short legs 33 (e.g., four) that are shorter than the long legs 32 are provided around the long legs 32 and protrude downward from the side surface portion 31. The short legs 33 position the support 3 almost horizontally on the hand-washing section when the long legs 32 are inserted into the drain of the hand-washing section.

The bottom surface portion 30 is provided with a peripheral wall 34 in the shape of a substantially rectangular frame that protrudes upward. An inner wall 41 of the cover member 4, which will be described later, is fitted into this peripheral wall 34. The upper end of the peripheral wall 34 is cut out in a concave shape at opposing positions to form notches 35. A through hole 36 is formed in the center of the area surrounded by the peripheral wall 34 of the bottom surface portion 30.

An opening 37A is formed at the outer position of the peripheral wall 34 of the bottom portion 30 to discharge water supplied to the hand washing section to the outside when the water enters the inside of the support 3. In addition, an opening 37B is formed in the side portion 31 to diffuse the aromatic components of the medicinal liquid to the outside.

As shown in Figs. 14 to 17, the cover member 4 has a generally rectangular top surface 40 in plan view, an inner wall 41 in the shape of a generally rectangular frame that hangs down from the top surface 40, and an outer wall 42 that is positioned outside the inner wall 41 and hangs down from the periphery of the top surface 40. By fitting the inner wall 41 to the inside of the peripheral wall 34, as shown in Fig. 10, the cover member 4 is placed on the bottom surface 30, and a buffer chamber 6 is formed between the bottom surface 30 and the cover member 4. The buffer chamber 6 is a space capable of storing a medicinal solution.

When the cover member 4 is placed on the bottom surface portion 30, the outer wall 42 is separated from the outer peripheral surface of the peripheral wall 34, and a pair of engagement protrusions 43 protruding outward from the lower end of the outer wall 42 engage one-to-one with a pair of engagement claws 38 provided on the bottom surface portion 30, thereby fixing the cover member 4 to the bottom surface portion 30.

The inner wall 41 is formed with a pair of notches 47 that extend vertically from its upper end to its lower end. The pair of notches 47 are arranged to correspond one-to-one with the pair of notches 35 in the peripheral wall 34 of the support body 3. When the cover member 4 is placed on the bottom surface portion 30, the notches 35 and the notches 47 coincide with each other to form air circulation holes that allow air to circulate within the buffer chamber 6.

The upper surface portion 40 is made up of a lower stage portion 40a, which is circular in plan view, at its center, and an upper stage portion 40b, which surrounds the lower stage portion 40a and is located at a higher position than the lower stage portion 40a. A cylindrical connecting member 44 is provided at the center of the lower stage portion 40a and is inserted into the mouth portion 21 of the drug solution container 2.

The connecting member 44 is provided on the lower portion 40a of the upper surface portion 40 so as to protrude above the upper portion 40b. The upper end of the connecting member 44 is cut at an angle to make it sharp so that it can easily break through the thin portion of the cap 22 when inserted into the mouth portion 21 of the drug solution container 2.

The lower section 40a of the upper surface section 40 is provided with a discharge member 45 that protrudes downward. The discharge member 45 is cylindrical and has a smaller diameter than the connection member 44, and is arranged concentrically with the connection member 44. The connection member 44 and the discharge member 45 are connected to each other, and the inside of the connection member 44 and the discharge member 45 form a liquid medicine passage that passes the liquid medicine from the liquid medicine container 2 to the guide member 5 described later. The inside of the discharge member 45 is separated from the buffer chamber 6, and the discharge member 45 can be fitted into the through hole 36 located in the center of the bottom surface section 30.

Multiple small-diameter liquid passage holes 46 (three in the illustrated example) are formed on the inside of the connection member 44 and on the outside of the discharge member 45 of the lower stage 40a. These liquid passage holes 46 introduce a portion of the liquid medicine discharged from the liquid medicine container 2 through the connection member 44 into the buffer chamber 6.

The buffer chamber 6 adjusts the amount of liquid medicine discharged from the liquid medicine container 2 even if a pressure change occurs inside the liquid medicine container 2 due to a temperature change. The buffer chamber 6 acts in the following way in response to a temperature change in the liquid medicine container 2.

For example, when the temperature rises and the liquid medicine container 2 is warmed, the air inside the liquid medicine container 2 expands, creating a positive pressure inside the liquid medicine container 2. In this case, the liquid medicine inside the liquid medicine container 2 is pushed out and discharged from the mouth 21, and the discharged liquid medicine flows from the connection member 44 and the discharge member 45 to the guide member 5, and also flows into the buffer chamber 6 through the liquid passage hole 46. This prevents the liquid medicine from flowing out excessively into the guide member 5.

On the other hand, when the temperature of the liquid medicine container 2 drops, for example by being cooled with running water, the air inside the liquid medicine container 2 contracts, causing negative pressure inside the liquid medicine container 2. In this case, the liquid medicine inside the buffer chamber 6, which is at atmospheric pressure or room pressure due to the action of the air circulation holes (notches 35 and 47), is sucked into the liquid medicine container 2 through the liquid passage hole 46. This prevents the water or diluted liquid medicine on the guide member 5 from being returned to the liquid medicine container 2 side through the discharge member 45 and the connection member 44. In addition, the discharge of the liquid medicine is prevented from being restricted by the negative pressure inside the liquid medicine container 2.

As shown in Figs. 1 to 3 and 10 to 13, the guide member 5 is plate-shaped and protrudes downward from the bottom surface portion 30 across the through hole 36. The guide member 5 guides the liquid medicine discharged from the liquid medicine container 2 to the support 3 via the connection member 44 and the discharge member 45 to a position where it comes into contact with liquid such as water flowing outside the support 3. The upper end of the guide member 5 is provided with a fitting protrusion 50 that protrudes above the bottom surface portion 30 through the through hole 36. The fitting protrusion 50 can be fitted into the discharge member 45 of the cover member 4. A vertical groove 51 extending from the upper end to the lower end is formed on the outer circumferential surface of the fitting protrusion 50, and this vertical groove 51 guides the liquid medicine passing through the discharge member 45 to the guide member 5 by capillary action.

The front and back surfaces of the guide member 5 are formed with a number of narrow grooves 52 extending in the vertical direction. The guide member 5 is located between the two long legs 32 and is inserted into the drain of the hand-washing section together with the long legs 32. The guide member 5 is formed slightly shorter than the long legs 32, and only its lower end is inserted into the drain. When the running water supplied to the hand-washing section comes into contact with the guide member 5, the medicinal solution on the front and back surfaces of the guide member 5 is washed away by the running water and flows into the water tank from the drain together with the running water. A water-shielding wall 39 having a substantially rectangular frame shape is provided between the guide member 5 and the long legs 32. The water-shielding wall 39 is formed even shorter than the guide member 5, and prevents the running water supplied to the hand-washing section from flowing back from the guide member 5 into the support 3.

Next, as shown in Figs. 1 and 2, one or more decorations 7 are contained in the liquid medicine container 2 together with the liquid medicine, thereby decorating the liquid medicine supply device 1 and improving the aesthetics of the liquid medicine supply device 1. The decorations 7 can be made of natural materials, or can be made of synthetic resin or glass, for example. The form of the decorations 7 is not particularly limited, and can be, for example, a sheet or a three-dimensional shape. The sheet can be made of nonwoven fabric or woven fabric made of natural fibers or synthetic resin fibers. The three-dimensional shape can be made of molded products such as synthetic resin or glass, or can be made of a sheet folded into a three-dimensional shape.

Examples of the decoration 7 include objects resembling plants such as flowers, leaves, stems, and grass; objects resembling trees; objects resembling animals; objects resembling insects; objects resembling fruit; objects resembling aquatic life (including marine life) such as starfish and coral; objects resembling stars, the moon, planets, etc.; spherical objects or objects resembling spheres such as beads and marbles; natural stones or artificial stones; sand and shells. In this embodiment, the decoration 7 is a sheet-like artificial flower.

The decoration 7 may remain in the liquid in the liquid container 2 and float gently in the liquid, or may rise up in the liquid and float on the surface of the liquid, or may be submerged in the liquid and sink to the bottom.

When the decoration 7 floats in the liquid inside the liquid container 2, the decorative effect of the decoration 7 is enhanced, and compared to the liquid supplying device 1 of this embodiment, which is installed at eye level, the decoration 7 inside the liquid supplying container 2 can be seen clearly when looking straight at the liquid supplying device 1, improving the aesthetic appearance of the liquid supplying device 1.

In addition, when the decoration 7 floats on the surface of the liquid medicine in the liquid medicine container 2, the decoration 7 moves up and down in the liquid medicine container 2 together with the liquid medicine level, so by checking the position of the decoration 7 in the liquid medicine container 2, the remaining amount of liquid medicine in the liquid medicine container 2 can be easily ascertained. In addition, when the liquid medicine supplying device 1 is viewed from above, the decoration 7 in the liquid medicine container 2 is easily visible because it floats on the top of the liquid medicine container 2, improving the aesthetic appearance of the liquid medicine supplying device 1, as opposed to a liquid medicine supplying device 1 that is installed on the floor.

In addition, if the decoration 7 is submerged at the bottom of the liquid medicine inside the liquid medicine container 2, when expressing, for example, submerged flowers or the ocean floor inside the liquid medicine container 2, the decoration 7 is maintained at the bottom of the liquid medicine container 2, so that the above-mentioned world view can be expressed well and the aesthetics of the liquid medicine supply device 1 can be improved.

One way to make the decoration 7 float in the chemical solution inside the chemical solution container 2 is to make the specific gravity of the decoration 7 when dry equal to that of the chemical solution. Here, "equal specific gravity" means that the specific gravities of the decoration 7 and the chemical solution are the same, or, if there is a difference in specific gravity, the difference is not so large that the decoration 7 floats or sinks. The specific gravity of the decoration 7 can be, for example, within a range of 0.9 to 1.1 times the specific gravity of the chemical solution.

In addition, one method for floating the decoration 7 on the surface of the chemical solution inside the chemical solution container 2 is, for example, to make the specific gravity of the decoration 7 when dry smaller than the specific gravity of the chemical solution. Here, "small specific gravity" refers to the specific gravity of the decoration 7 being smaller than the specific gravity of the chemical solution to the extent that the decoration 7 floats, and the specific gravity of the decoration 7 can be, for example, smaller than 0.9 times the specific gravity of the chemical solution.

In addition, one method of sinking the decoration 7 to the bottom of the chemical solution inside the chemical solution container 2 is, for example, to make the specific gravity of the decoration 7 when dry greater than the specific gravity of the chemical solution. Here, "higher specific gravity" means that the specific gravity of the decoration 7 is greater than the specific gravity of the chemical solution to the extent that the decoration 7 sinks, and the specific gravity of the decoration 7 can be, for example, greater than 1.1 times the specific gravity of the chemical solution.

The specific gravity of the above-mentioned liquid medicine can be measured at room temperature (25°C) using a standard hydrometer (1-5659 (small size), manufactured by Nippon Keiryoki Kogyo Co., Ltd.). For example, if the liquid medicine has a specific gravity of 0.94 to 1.00, use a No. 5 hydrometer; if the specific gravity is 1.00 to 1.06, use a No. 6 hydrometer; if the specific gravity is 1.06 to 1.12, use a No. 7 hydrometer; if the specific gravity is 1.12 to 1.18, use a No. 8 hydrometer; if the specific gravity is 1.18 to 1.24, use a No. 9 hydrometer; if the specific gravity is 1.24 to 1.28, use a No. 10 hydrometer. Specifically, 100 ml of the liquid medicine is placed in a 100 ml graduated cylinder, the hydrometer is floated in the liquid, and the specific gravity is measured by reading the value at the intersection of the liquid level and the black line of the hydrometer while the hydrometer is floating stably.

The specific gravity of the above-mentioned decoration 7 can be calculated by pouring a certain amount of distilled water into a graduated cylinder with fine markings (e.g. 0.2 ml), immersing the decoration 7 in the distilled water until it is submerged, reading the increase in the markings (the volume of decoration 7), and then combining the previously measured weight of the dry decoration 7 with the increase in the markings that was read (the volume of decoration 7).

The decoration 7 preferably has the property of not substantially absorbing the chemical solution. By the decoration 7 not substantially absorbing the chemical solution, the specific gravity of the decoration 7 hardly changes even when it is stored in the chemical solution container 2 together with the chemical solution, and the state of the decoration 7 in the chemical solution (the above-mentioned floating, floating or sinking state) can be maintained until the end of the use of the chemical solution supplying device 1. Note that the property of the decoration 7 of not substantially absorbing the chemical solution means that in addition to not absorbing any chemical solution at all, the decoration 7 absorbs some chemical solution, but only to the extent that the state of the decoration 7 in the chemical solution (the above-mentioned floating, floating or sinking state) can be maintained until the end of the use of the chemical solution supplying device 1.

The decoration 7 does not necessarily have to have the property of not substantially absorbing the chemical solution, but may have the property of absorbing the chemical solution. In this case, in a dry state, the specific gravity of the decoration 7 is smaller than that of the chemical solution and floats on the surface of the chemical solution, but by absorbing the chemical solution, the decoration 7 may float in the chemical solution or sink to the bottom. Also, in a dry state, the specific gravity of the decoration 7 is equal to that of the chemical solution and floats in the chemical solution, but by absorbing the chemical solution, the decoration 7 may sink to the bottom.

According to the liquid medicine supply device 1 of the present embodiment described above, the liquid medicine container 2, whose interior is visible, contains the decorative object 7 together with the liquid medicine, so that the liquid medicine supply device 1 itself has a beautiful appearance due to the decorative effect of the decorative object 7. Therefore, for example, when the liquid medicine supply device 1 is installed in the hand-washing section above the water tank of a flush toilet, no other decorative object is required to decorate the hand-washing section. Therefore, it is sufficient to secure a space in the hand-washing section that is the same size as that of a conventional liquid medicine supply device, and a large space in the hand-washing section is not required for decoration. Furthermore, since the various openings 37A, 37B formed in the liquid medicine supply device 1 and the drain of the hand-washing section are not blocked, the desired effect of the liquid medicine supply device 1 can be obtained.

In addition, on the inner surface of the liquid medicine container 2, a guide groove 26 is recessed outside the discharge port 22, with a portion of the guide groove 26 connected to the discharge port 22 to guide the liquid medicine to the discharge port 22. Therefore, even if the decoration 7 in the liquid medicine container 2 sinks to the bottom of the liquid medicine or sinks due to a decrease in the amount of liquid medicine during use, as shown in FIG. 7, and the decoration 7 covers the discharge port 22 and blocks it, the liquid medicine in the liquid medicine container 2 is discharged from the discharge port 22 to the outside of the liquid medicine container 2 through the guide groove 26. Therefore, the discharge of the liquid medicine from the discharge port 22 is not hindered by the decoration 7 in the liquid medicine container 2, and the liquid medicine can be supplied without any problems.

Although the 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, in the above embodiment, multiple guide grooves 26 extend radially from the discharge outlet 22, but the shape of the guide grooves 26 is not particularly limited as long as they are capable of guiding the liquid medicine to the discharge outlet 22 when the decoration 7 covers the discharge outlet 22. For example, as shown in FIG. 18, the guide groove 26 may be recessed into the inner surface of the liquid medicine container 2 so as to have a ring shape having a predetermined width so as to surround the discharge outlet 22. The inner peripheral edge of this guide groove 26 is connected to the discharge outlet 22, and the outer peripheral edge extends outside the discharge outlet 22.

Even in the embodiment of FIG. 18, if the decoration 7 in the liquid medicine container 2 sinks to the bottom of the liquid medicine or sinks due to a decrease in the amount of liquid medicine during use, as shown in FIG. 19, even if the decoration 7 covers the discharge port 22, the liquid medicine in the liquid medicine container 2 is discharged from the discharge port 22 to the outside of the liquid medicine container 2 through the guide groove 26. Therefore, the discharge of the liquid medicine from the discharge port 22 is not hindered by the decoration 7 in the liquid medicine container 2, and the liquid medicine can be supplied without any problems.

In addition, in the above embodiment, the streak-like bends 8 are formed on the peripheral surface of the liquid medicine container 2, but the streak-like bends 8 do not have to be formed on the peripheral surface of the liquid medicine container 2. If the streak-like bends 8 are not formed on the peripheral surface of the liquid medicine container 2, as shown in FIG. 9, the decoration 7 inside the liquid medicine container 2 can be clearly seen, and the decoration 7 can be specifically expressed. Therefore, depending on the shape of the decoration 7, the decorative effect of the decoration 7 can be increased.

In addition, in the above embodiment, a three-dimensional pattern 9 is formed on the peripheral surface of the liquid medicine container 2, but the three-dimensional pattern 9 does not have to be formed on the peripheral surface of the liquid medicine container 2, just like the streak-like bent portion 8.

In addition, in the above embodiment, an on-tank type medicinal liquid supplying device that is installed in the hand-washing section above the water tank of a flush toilet is described as an example of a type that supplies medicinal liquid by inserting a guide member 5 into the drain of the hand-washing section, but the present invention can also be suitably applied to various types of medicinal liquid supplying devices, such as a type that supplies medicinal liquid directly to the hand-washing section.

In addition, the above embodiment describes an on-tank type medicinal liquid supplying device that is installed in the hand washing section above the water tank of a flush toilet, but the present invention can also be suitably applied to a type of medicinal liquid supplying device that is hung from the rim of a toilet bowl.

In addition, in the above embodiment, a medicinal liquid supplying device for a flush toilet is described as an example, but the present invention can also be suitably applied to a type of medicinal liquid supplying device that is placed on the floor or shelf of a room such as a living room or an entrance hall and supplies medicinal liquid by volatilizing or transpiring to scent or deodorize the indoor space.
