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.

In flush toilets, for example, an on-tank type chemical solution supply is installed in the hand washing section installed above the water storage tank to supply chemical solutions for fragrance, deodorization, and cleaning to the flushing water (flush water). The device is traditionally used.

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 basin is sometimes decorated with ornaments such as artificial flowers and decorations to improve the aesthetic appearance of the inside of the toilet.

However, in order to decorate the hand-washing section in which the chemical solution supply device is installed with the above-mentioned decorations, a large space is required in the hand-washing section. In addition, decorations can block the various openings formed in the chemical solution supply device and the drain in the hand washing area, causing problems such as the desired effect of the chemical solution supply device not being obtained and the problem of water clogging. There is a risk that this may occur. Such a problem may also occur in chemical liquid supply devices other than the on-tank type.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a chemical liquid supply device that has an aesthetic appearance. Another object of the present invention is to provide a chemical liquid supply device in which the discharge of the chemical liquid from the discharge port is not obstructed by decorations housed in the chemical liquid container.

The drug solution supply device of the present invention includes a drug solution container whose interior is visible, a drug solution stored in the drug solution container, and a support that supports the drug solution container from below with the drug solution outlet facing downward. and a decoration housed in the liquid medicine container together with the liquid medicine, wherein the decoration has a sheet shape and includes a portion at least partially bent to have a V-shape in cross-section. Features.

In the drug solution supply device of the present invention, it is preferable that the decoration includes a plurality of sheet pieces formed by folding, and that the sheet pieces do not include a portion that fits the outer edge contour of the discharge port in a plan view.

Further, in the chemical solution supply device of the present invention, the decoration includes at least one first sheet piece portion bent upward and at least one second sheet piece portion bent downward. It is preferable.

Further, in the chemical solution supply device of the present invention, the ornament includes a plurality of the first sheet piece portions and the second sheet piece portions, and the first sheet piece portion and the second sheet piece portion each include a plurality of the first sheet piece portions and the second sheet piece portions. Preferably, the pieces are arranged alternately in the circumferential direction.

Furthermore, in the chemical solution supply device of the present invention, the first sheet piece is bent into a V-shape in cross section so that the center line in the width direction is the bottom, and the second sheet piece is It is preferable that it is bent in a V-shape when viewed in cross section so that the center line in the width direction is the top.

In addition, in the drug solution supply device of the present invention, it is preferable that the sheet pieces are arranged in multiple parts in the circumferential direction and are folded up and down in the same direction.

Further, in the chemical solution supply device of the present invention, it is preferable that the sheet piece portion is bent into a V-shape in cross-section so that the center line in the width direction is the top or bottom.

According to the present invention, the decoration is housed together with the medicine in the inside of the medicine container which can be visually checked, and the medicine supply device itself has an aesthetic appearance due to the decorative effect of the decoration. becomes unnecessary. Therefore, for example, if a chemical solution supply device is installed in the hand washing section above the water storage tank of a flush toilet, it is sufficient to secure the same amount of space as the conventional chemical solution supply device, but a large space is required in the hand washing section for decoration. I don't. Moreover, since the various openings formed in the chemical solution supply device and the drain port of the hand washing section are not blocked, the desired effect of the drug solution supply device can be obtained.

In addition, since the decoration has a three-dimensional shape formed by folding the sheet, even if the decoration covers the discharge port inside the liquid medicine container, a gap will be created between the discharge port and the decoration. Also, even if multiple decorations are misaligned and overlap on the discharge port, gaps will be created between the decorations. Therefore, the liquid medicine inside the liquid medicine container is discharged from the discharge port to the outside of the liquid medicine container through the gaps between the decorations and the gaps between the decorations and the discharge port. Therefore, the discharge of the liquid medicine from the discharge port is not hindered by the decoration inside the liquid medicine container, and the liquid medicine can be supplied without any problems.

FIG.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 1 to 3 show the external configuration of a chemical liquid supply device 1 that is an embodiment of the present invention. The chemical solution supply device 1 of this embodiment is of a type that is installed in a dish-shaped hand washing section provided above a water storage tank in 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 FIGS. 3 to 5, the drug solution container 2 includes a body portion 20 that can contain a drug solution, and a cylindrical mouth portion 21 that is continuously formed integrally with the body portion 20. In addition, since the drug solution container 2 is attached to the support body 3 in an upside-down state with the mouth portion 21 facing downward during use, in the following explanation, the mouth portion 21 side of the drug solution container 2 will be referred to as the “lower side” and the body portion will be referred to as the “lower side”. The 20 side is defined as the "upper side".

The inside of the drug solution container 2 can be visually recognized from the outside, and for example, the inside can be made visible by making the entire container transparent or translucent. Note that at least a portion of the drug solution container 2 may be made transparent or semitransparent so that the inside thereof can be visually recognized. The body portion 20 and mouth portion 21 of the chemical liquid container 2 can be made of glass, synthetic resin, or the like, for example. A discharge port 22 is opened at the bottom of the body 20 and communicates with the mouth 21 to discharge the medicinal liquid in the body 20 . A cap 23 is removably placed over the mouth portion 21. The cap 23 can be made of soft synthetic resin, for example. The cap 23 is provided with a closing portion 24 via a thin wall portion 25 at a portion that closes the mouth portion 21 .

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.

Since the striped bent portion 8 is formed on the circumferential surface of the drug solution container 2, as shown in FIG. The decorations 7 inside appear blurry, large, or refracted. On the other hand, if the linear bent portion 8 is not formed on the circumferential surface of the liquid medicine container 2, the decoration 7 inside the liquid medicine container 2 can be clearly seen as shown in FIG. In this way, by forming the linear bent portion 8 on the circumferential surface of the liquid medicine container 2, the decorations 7 inside the liquid medicine container 2 are not clearly visible, making it possible to express an abstract design. Depending on the form of the decoration 7, the decorative effect of the decoration 7 can be increased. Note that the decorations 7 shown in FIGS. 6 and 7 are artificial flowers.

In addition, since the linear bent portion 8 is formed over one circumferential direction of the circumferential surface of the liquid medicine container 2, the decorations 7 inside the liquid medicine container 2 can be seen from any position around the liquid medicine container 2. can be expressed using the abstract design described above. In addition, since the chemical solution supply device 1 of this embodiment is generally installed at eye level, the drug solution supply device 1 is often viewed straight; By forming the bent portion 8, the decoration 7 inside the drug solution container 2 can be effectively expressed with the above-mentioned abstract design.

One or more three-dimensional patterns 9 are formed on the circumferential surface of the liquid medicine container 2 when viewed from the front and/or from the back. The three-dimensional pattern 9 is formed by a convex portion formed by protruding a portion of the circumferential surface of the body portion 20 outward, and/or by recessing a portion of the circumferential surface of the body portion 20 inward. It consists of a concave part. In this embodiment, the three-dimensional pattern 9 having one desired design as a whole is formed by a combination of a plurality of convex portions and concave portions. may be formed.

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 8 to 11, the support body 3 is formed into a cup shape with an open top, and supports the connected drug solution container 2 from below. The support body 3 includes a bottom part 30, a side part 31, a cover member 4, and a guide member 5. Like the drug solution container 2, the support body 3 has a length in the first direction (left-right direction in FIG. 1) that is longer than the length in the second direction (left-right direction in FIG. 2) perpendicular to the first direction (left-right direction in FIG. 2) when viewed from above. It has a long oblong external shape. In this embodiment, the support body 3 is formed into a substantially elliptical shape in plan view. When the shape of the hand-washing section is horizontally elongated, the drug solution supply device 1 is installed so that the first direction (the left-right direction of the support 3 and the drug-solution container 2) coincides with the left-right direction of the hand-washing section. This support body 3 can be formed of synthetic resin such as polyethylene, polypropylene, polyethylene terephthalate, etc., and has flexibility.

The bottom portion 30 is provided with a plurality of (two in the illustrated example) long legs 32 that protrude downward. Further, around the long legs 32, a plurality of (for example, four) short legs 33 shorter than the long legs 32 are provided so as to protrude downward from the side surface portion 31. The plurality of short legs 33 position the support 3 substantially horizontally on the hand washing section with the long legs 32 inserted into the drain port 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 side of the peripheral wall 34 of the bottom part 30 for draining the water supplied to the hand washing part to the outside when it enters the inside of the support body 3. Furthermore, an opening 37B is formed in the side surface portion 31 for diffusing the aromatic component of the chemical liquid to the outside.

As shown in Figs. 12 to 15, the cover member 4 has a generally rectangular top surface portion 40 in a plan view, an inner wall 41 in the shape of a generally rectangular frame that hangs down from the top surface portion 40, and an outer wall 42 that is positioned outside the inner wall 41 and hangs down from the periphery of the top surface portion 40. By fitting the inner wall 41 to the inside of the peripheral wall 34, as shown in Fig. 8, the cover member 4 is placed on the bottom surface portion 30, and a buffer chamber 6 is formed between the bottom surface portion 30 and the cover member 4. The buffer chamber 6 is a space capable of storing a medicinal solution.

The outer wall 42 is separated from the outer peripheral surface of the peripheral wall 34 when the cover member 4 is installed on the bottom part 30, and a pair of engagement protrusions 43 protruding outward from the lower end of the outer wall 42 are attached to the bottom part 30. The cover member 4 is fixed to the bottom surface portion 30 by engaging one-on-one with a pair of engaging claws 38 provided on the bottom surface portion 30 .

A pair of notches 47 are formed in the inner wall 41 and extend in the vertical direction from its upper end to its lower end. The pair of notches 47 are arranged in one-to-one correspondence with the pair of notches 35 in the peripheral wall 34 of the support body 3. When the cover member 4 is installed on the bottom surface part 30, the notch 35 and the notch 47 coincide with each other, thereby forming an air circulation hole through which air circulates 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 part 40a of the upper surface part 40 so as to protrude upward from the upper part 40b. The upper end of the connecting member 44 is cut diagonally and has a sharp point so that the connecting member 44 can easily break through the thin wall portion of the cap 22 when inserted into the mouth portion 21 of the liquid medicine 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 8 to 11, the guide member 5 has a plate shape and protrudes downward from the bottom surface portion 30 so as to cross the through hole . The guide member 5 is for guiding the chemical liquid discharged from the chemical liquid container 2 to the support body 3 via the connection member 44 and the discharge member 45 to a position where it comes into contact with a liquid such as water flowing outside the support body 3. It is. A fitting protrusion 50 is provided at the upper end of the guide member 5 and projects upward from the bottom portion 30 through the through hole 36 . The fitting protrusion 50 can be fitted into the ejection 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 the vertical groove 51 guides the chemical liquid passing through the discharge member 45 to the guide member 5 by capillary action.

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

Next, as shown in FIGS. 1 and 2, one or more decorations 7 are housed in the chemical liquid container 2 together with the chemical liquid to decorate the chemical liquid supply device 1 and improve the aesthetic appearance of the chemical liquid supply device 1. Improve. The decoration 7 is in the form of a sheet made of nonwoven fabric or woven fabric made of natural fibers, synthetic resin fibers, etc., and is formed into a three-dimensional shape by folding the sheet along at least one crease line. . The form of the ornament 7 is not particularly limited, and examples thereof include those resembling plants such as flowers, leaves, and grass, feathers, ribbons, and the like.

The decoration 7 may stay in the drug solution and float in the drug solution, float up in the drug solution and float on the surface of the drug solution in the drug solution container 2, or may float in the drug solution and float on the surface of the drug solution. It may be immersed in water and sink to the bottom of the chemical solution.

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 sunk to the bottom of the chemical solution in the chemical solution container 2, when expressing, for example, a submerged flower or the seabed in the drug solution container 2, the decoration 7 will be sunk to the bottom of the drug solution container 2. Since this is maintained, the above-mentioned world view can be expressed well, and the aesthetic appearance of the chemical liquid 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 decoration 7 described above can be determined by pouring a certain amount of distilled water into a measuring cylinder with a fine scale (for example, 0.2 ml), and then pouring the decoration 7 into the distilled water until it is submerged. It can be calculated by reading the weight of the decoration 7 in a dry state measured in advance (volume of the decoration 7) and the read increment on the scale (volume of the decoration 7).

It is preferable that the ornament 7 has a property of not substantially absorbing the medicinal solution. Since the ornament 7 does not substantially absorb the medicinal solution, its specific gravity hardly changes even when the ornament 7 is accommodated in the medicinal solution container 2 together with the medicinal solution, and the state of the ornament 7 in the medicinal solution (the above-mentioned flotation, (floating or sedimented state) can be maintained until the end of use of the chemical solution supply device 1. Note that the property of the decoration 7 not to substantially absorb the chemical liquid means not only that it does not absorb the chemical liquid at all, but also that it absorbs some of the chemical liquid, but even if it absorbs the chemical liquid, the state of the decoration 7 in the chemical liquid (the above-mentioned levitation) , floating or settling state) can be maintained to the extent that the chemical solution supply device 1 can be maintained until the end of its use.

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.

If the decoration 7 housed in the liquid medicine container 2 sinks below the liquid medicine, or if the decoration 7 in the liquid medicine container 2 settles due to the decrease in the amount of medicine due to use, the discharge port 22 of the liquid medicine container 2 may be If the decoration 7 covers the discharge port 22, if the decoration 7 is sheet-like, the discharge port 22 may be covered and blocked by the decoration 7, and the discharge of the medicinal liquid from the discharge port 22 may be inhibited. Therefore, the decoration 7 is designed in a three-dimensional shape so that even if it covers the discharge port 22, it does not completely block the discharge port 22.

Specifically, as shown in FIG. 16, the decoration 7 includes a portion that is bent along at least one crease line 71 to have a V-shape when viewed in cross section in at least one direction. Thereby, even if the decoration 7 covers the discharge port 22, a gap is formed between the decoration 7 and the discharge port 22. Therefore, the discharge port 22 can be prevented from being blocked by the decoration 7, and the drug solution in the drug solution container 2 is discharged from the discharge port 22 to the outside of the drug solution container 2 through this gap. Furthermore, as shown in FIG. 17, even if a plurality of decorations 7 (two in the figure) overlap each other on the discharge port 22, gaps are formed between the decorations 7, so that the inside of the drug solution container 2 is removed. The chemical liquid passes through the gaps between the decorations 7 and the gaps between the decorations 7 and the discharge port 22, and is discharged from the discharge port 22 to the outside of the chemical liquid container. Therefore, the decorations 7 in the liquid medicine container 2 do not obstruct the discharge of the liquid medicine from the discharge port 22, and the liquid medicine can be supplied without any problem.

In Fig. 16, the decorative object 7 is folded along one fold line 71, forming a V-shape in cross section in one direction, but as shown in Fig. 18, the decorative object 7 may include multiple V-shaped portions in cross section in one direction by folding the decorative object 7 along multiple (two in the figure) parallel fold lines 71. In Fig. 18(A), the two sheet pieces 70 on both sides are folded in the same vertical direction relative to the central sheet piece 70, while in Fig. 18(B), the two sheet pieces 70 on both sides are folded in opposite vertical directions relative to the central sheet piece 70. By including a sheet piece portion (first sheet piece portion) 70 folded upward as shown in FIG. 18(B) and a sheet piece portion (second sheet piece portion) 70 folded downward, the decorative object 7 has a top-bottom symmetrical shape, and even if the decorative object 7 is turned upside down inside the medicinal liquid container 2, the appearance of the decorative object 7 hardly changes, and the decorative effect of the decorative object 7 can be maintained.

In Figures 16 and 18, the decoration 7 includes multiple sheet pieces 70 arranged in succession with fold lines 71 between them, but as shown in Figure 19 (A), it is preferable to design the outer edge contour of each sheet piece 70 so that no matter how the sheet piece 70 is overlapped on the discharge outlet 22 in a plan view, the portion that completely fits the periphery of the discharge outlet 22 is not included inside. This makes it possible to create a gap between the sheet piece 70 and the discharge outlet 22, without the sheet piece 70 covering the discharge outlet 22, even if the sheet piece 70 covers the discharge outlet 22.

Alternatively, as shown in FIG. 19(B), each sheet piece portion 70 is preferably bent into a V-shape in cross-section so that the center line 72 in the width direction is the top or bottom (bottom in the illustration). . Thereby, even if the sheet piece part 70 covers the discharge port 22, a gap can be created between the sheet piece part 70 and the discharge port 22 without covering the discharge port 22.

20, the decoration 7 may include a plurality of (four in the figure) sheet pieces 70 arranged in the circumferential direction. The decoration 7 shown in FIG. 20 is folded along two mutually orthogonal fold lines 71, so that it has a V-shape in cross section in two mutually orthogonal directions. In addition, in the decoration 7 shown in FIG. 20, all the sheet pieces 70 are folded upward, and all the sheet pieces 70 are folded in a V-shape in cross section so that the center line in the width direction is the top or bottom (bottom in the figure). As a result, as in the example shown in FIG. 19(B), even if the sheet piece 70 covers the discharge outlet 22, a gap can be created between the sheet piece 70 and the discharge outlet 22 without covering the discharge outlet 22. In addition, in the decorative object 7 shown in FIG. 20, similar to the example shown in FIG. 19(A), by designing the outer edge contour of the sheet piece 70 so that the portion that completely fits the periphery of the discharge outlet 22 is not included inside, even if the sheet piece 70 covers the discharge outlet 22, the sheet piece 70 can create a gap between the discharge outlet 22 and the sheet piece 70 without covering the discharge outlet 22.

As shown in FIG. 21, the decoration 7 may be formed by folding multiple (four in the figure) sheet pieces 70 arranged in the circumferential direction in opposite directions, alternately folded up and down along the fold lines 71 located at the base ends, or by arranging sheet pieces 70 folded upward (first sheet piece) 70 and sheet pieces 70 folded downward (second sheet piece) 70 alternately arranged in the circumferential direction. This gives the decoration 7 a top-to-bottom symmetrical shape, so that even if the decoration 7 is turned upside down inside the drug solution container 2, the appearance of the decoration 7 hardly changes, and the decorative effect of the decoration 7 can be maintained.

In addition, in the decoration 7 shown in FIG. 21, the sheet piece portion (first sheet piece portion) 70 that is bent upward is bent into a V-shape in cross section so that the center line in the width direction is the bottom. The sheet piece portion (second sheet piece portion) 70 that is bent downward is bent into a V-shape when viewed in cross section so that the center line in the width direction is the top. As a result, even if the decoration 7 is made into a vertically symmetrical shape and the sheet piece part 70 covers the discharge port 22, as in the example shown in FIG. A gap can be created between the discharge port 22 and the discharge port 22 without covering the discharge port 22. In addition, in the decoration 7 shown in FIG. 21, similarly to the example shown in FIG. By designing, even if the sheet piece part 70 covers the discharge port 22, a gap may be created between the sheet piece part 70 and the discharge port 22 without covering the discharge port 22.

Furthermore, in the ornament 7 shown in FIG. 21, the outer region Y of each sheet piece portion 70 is further bent with respect to the inner region 70X. Specifically, in the sheet piece portion (first sheet piece portion) 70 that is bent upward, the outer region 70Y is bent upward with respect to the inner region 70X, and the sheet piece portion (first sheet piece portion) that is bent downward is In the first sheet piece 70, the outer region 70Y is bent downward with respect to the inner region 70X. As a result, as shown in FIG. 22 (particularly FIG. 22(B)), the decorative object 7 is moved by the further downward outer region 70Y of the downwardly bent sheet piece (first sheet piece) It becomes easier to stand on the bottom of the container 2, and the possibility that the sheet piece portion 70 will be disposed at the discharge port 22 so as to cover the discharge port 22 is reduced. Therefore, a gap is likely to be formed between the decoration 7 and the discharge port 22. In addition, when another decoration 7 is shifted and overlapped with the decoration 7, the further upward outer region 70Y of the upwardly bent sheet piece portion (first sheet piece portion) 70 allows the decoration 7 to be overlapped upwardly. A gap is likely to be formed between the decorative object 7 and the decorative object 7. Therefore, the medicinal solution in the medicinal solution container 2 can be well discharged from the ejection port 22 to the outside of the medicinal solution container 2 through the gaps between the decorations 7 and the gaps between the decorations 7 and the ejection port 22.

An example of a method for folding the sheet described above to form the three-dimensional decoration 7 is to shape the sheet into a desired three-dimensional shape by sandwiching the sheet between molds and applying heat, for example. However, the method is not limited to the above method, and the sheet may be formed into a desired three-dimensional shape by forming fold lines directly on the sheet and folding the sheet along the fold lines.

The decoration 7 is preferably large enough that it cannot pass through the discharge port 22. For example, it is preferable that its maximum length is greater than the outer diameter of the discharge port in at least one direction around the 360° circumference in a plan view. This makes it possible to prevent the decoration 7 from passing through the discharge port 22 and escaping from the body 20 of the liquid medicine container 2.

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, since the decoration 7 has a three-dimensional shape formed by folding the sheet, even if the decoration 7 covers the discharge outlet 22 inside the liquid medicine container 2, a gap will be created between the discharge outlet 22 and the decoration 7. Even if multiple decorations 7 are misaligned and overlap on the discharge outlet 22, a gap will be created between the decorations 7. Therefore, the liquid medicine inside the liquid medicine container 2 is discharged from the discharge outlet 22 to the outside of the liquid medicine container 2 through the gaps between the decorations 7 and the gaps between the decorations 7 and the discharge outlet 22. Therefore, the discharge of the liquid medicine from the discharge outlet 22 is not hindered by the decoration 7 inside 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, the specific shape of the decorative object 7, and how the sheet is folded to form a three-dimensional shape, is not limited to the shape of the embodiment described above, and various other shapes can be adopted.

Further, in the embodiment described above, the linear bent portion 8 is formed on the circumferential surface of the liquid medicine container 2, but the linear bent portion 8 does not need to be formed on the circumferential surface of the liquid medicine container 2. If the striped bent portion 8 is not formed on the circumferential surface of the liquid medicine container 2, the decoration 7 inside the liquid medicine container 2 can be clearly shown as shown in FIG. can do. Therefore, depending on the form of the decoration 7, the decorative effect of the decoration 7 can be increased.

Further, in the above embodiment, the three-dimensional pattern 9 is formed on the circumferential surface of the liquid medicine container 2, but the three-dimensional pattern 9 may not be formed on the circumferential surface of the liquid medicine container 2, like the linear bent part 8. good.

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.
