Description

The present invention relates to a chemical solution supply device that supplies chemical solutions for fragrance, deodorization, cleaning, etc. to the outside, and is installed in, for example, a dish-shaped hand washing section provided above the water storage tank of a flush toilet to supply chemical solutions for flushing. This invention relates to a chemical solution supply device that supplies flowing water (flush water).

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.

This on-tank type chemical solution supply device includes, for example, a drug container that stores a drug solution, and a cup-shaped support that supports the drug solution container from below with the drug solution outlet facing downward. There is a known device in which a guide member and a plurality of long legs protruding from the bottom of the hand washing section are inserted into the drain port of the hand washing section (for example, see Patent Document 1). In this chemical liquid supply device, the chemical liquid is discharged onto the support from the discharge port of the chemical liquid container, and the chemical liquid discharged onto the support is guided and held by the guide member. When the running water supplied to the hand-washing section from the water tap placed above the hand-washing section flows toward the drain, it sweeps away the medicinal solution on the guide member, so that the water flows from the drain into the water storage tank along with the running water. It is configured.

In flush toilets, the hand basin is sometimes decorated with ornaments such as artificial flowers and decorations to improve the aesthetics of the interior 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.

JP2013-79496A

Therefore, the applicant of the present application has proposed a chemical liquid supply device in which a decorative object is stored together with the chemical liquid in a chemical liquid container, and the design of the device itself is improved by the decorative effect of the decorative object (Japanese Patent Application No. 2018-242523). . In this chemical solution supply device, for example, a plurality of sheet-like decorations shaped like flowers are floated on the surface of the chemical solution, suspended in the drug solution, or submerged at the bottom of the drug solution, thereby improving the design of the device. is improving.

In a drug solution supply device in which a plurality of sheet-like decorations are housed in a drug solution container, the plurality of decorations move due to the flow of the drug solution as the drug solution in the drug solution container decreases with use. Some decorations may overlap other decorations. Here, if the two decorations completely overlap, the two overlapping decorations will look like one and it will not be possible to visually recognize that there are multiple decorations, which may reduce the design quality. Furthermore, if the user directly touches the decoration in the chemical liquid with his/her hand in order to separate two overlapping decorations, the chemical liquid will adhere to the hand, resulting in problems such as getting the hands dirty.

Furthermore, if the decoration settles due to the amount of the chemical in the liquid medicine container being reduced during use, the decoration may cover the discharge port of the liquid medicine container. If a sheet-like decoration covers the ejection port, the ejection port may be blocked and the ejection of the medicinal liquid from the ejection port may be inhibited.

The present invention has been made to solve the above problems, and improves the design by storing a plurality of sheet-like decorations in a drug solution container, and also improves the design of the sheet-like decorations by accommodating a plurality of sheet-like decorations in a drug solution container. It is an object of the present invention to provide a chemical solution supply device that can suppress deterioration in design even if the device overlaps the device, and can also prevent a sheet-like decoration from obstructing the ejection of the drug solution from the ejection port.

TECHNICAL FIELD The present invention relates to a chemical liquid supply device that supplies chemical liquids for fragrance, deodorization, cleaning, etc. to the outside. The drug solution supply device of the present invention includes a drug solution container that has a discharge port at the bottom and whose interior is visible, a drug solution stored in the drug solution container, and a plurality of sheet-shaped sheets that are accommodated in the drug solution container together with the drug solution. each of the decorations includes a base and a plurality of extensions arranged around the base and connected to the base, each of the extensions comprising: It is characterized in that at least a portion of the distal end side is bent in an upside-down direction with respect to the extension portions adjacent to at least one of both sides of the base portion in the circumferential direction.

In the chemical liquid supply device of the present invention, the plurality of decorations include decorations having an even number of extension parts, and the decoration has an extension part at least a part of which is bent upward on the tip side. and extending portions, at least a portion of which is bent downward, may be arranged alternately in the circumferential direction of the base portion.

Further, in the chemical solution supply device of the present invention, the plurality of decorations include decorations in which the number of extension parts is an odd number, and the decorations include a decoration except between a pair of adjacent extension parts. , an extension portion in which at least a portion of the tip side is bent upward and an extension portion in which at least a portion of the tip side is bent downward are arranged alternately in the circumferential direction of the base portion; I can do it.

Further, in the chemical liquid supply device of the present invention, each of the extending portions may be configured such that when it is placed over the ejection port, it does not include a portion where the periphery of the ejection port fits in when viewed from above. can.

According to the present invention, decorations are housed together with the medicine in a medicine container whose interior is visible, and the decorative effect of the decorations improves the design of the medicine supply device itself and improves the aesthetics of the toilet interior. No other decorations are needed for decoration. 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, the plurality of decorations housed in the liquid medicine container have a three-dimensional shape in which two circumferentially adjacent extensions are bent in opposite directions. Even if they overlap, the multiple overlapping decorations are prevented from completely overlapping, and it can be seen at a glance that one decoration is placed on top of the other. Therefore, it is possible to prevent the plurality of overlapping decorations from appearing as one and not being able to visually recognize the presence of a plurality of decorations, thereby suppressing deterioration in the design of the chemical liquid supply device.

In addition, even if a decoration covers the discharge port in the liquid medicine container, a gap is created between the discharge port and the decoration. Furthermore, even if a plurality of decorations overlap the discharge port, gaps will be created between the decorations. Therefore, the medicinal liquid in the medicinal liquid container is discharged from the ejection opening to the outside of the medicinal liquid container through the gaps between the ornaments and the gaps between the ornaments and the ejection opening. Therefore, the decorations in the liquid medicine container prevent the discharge of the liquid medicine from the discharge port from being obstructed, and the supply of the liquid medicine can be carried out smoothly.

1 to 3 show a chemical liquid supply device 1 which is an embodiment of the present invention. Note that the chemical solution supply device 1 of this embodiment is installed in a dish-shaped hand washing section provided above a water storage tank in a flush toilet, for example, for deodorizing and deodorizing the interior space of the toilet and for cleaning the toilet bowl. Type (on-tank type) is given as an example.

The drug solution supply device 1 includes a drug solution container 2, a drug solution stored in the drug solution container 2, a support body 3 to which the drug solution container 2 is removably attached, and a decoration 7 accommodated in the drug solution container 2 together with the drug solution. . The chemical solution supply device 1 is installed in a hand-washing section such that the guide member 5 and the plurality of long legs 32 protruding from the bottom surface 30 of the support 3 are inserted into the drain port of the hand-washing section. Each member of the chemical liquid supply device 1 will be explained below.

As shown in FIGS. 1 to 4, the drug solution container 2 includes a body portion 20 capable of containing a drug solution, and a cylindrical mouth portion 21 integrally formed continuously 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 drug solution container 2 is used upside down with the cap 23 attached to the mouth portion 21 with the cap 23 (discharge port 22 of the body portion 20) facing downward. When in use, the cylindrical connecting member 44 of the support 3, which will be described later, is inserted into the opening 21 of the liquid medicine container 2 so as to break through the closing part 24 of the cap 23, thereby connecting the liquid medicine container 2 and the support 3. is connected. As a result, the chemical liquid in the chemical liquid container 2 passes through the mouth portion 21 from the discharge port 22 and is discharged onto the support body 3 via the connecting member 44 . The connecting member 44 of the support body 3 fits into the opening 21 of the drug solution container 2, so that the connecting member 44 is difficult to slip out from the opening 21.

Next, as shown in FIGS. 1 to 3 and 5 to 8, 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. Similarly to the drug solution container 2, as shown in FIG. 6, the support body 3 has a length in a first direction (left-right direction in FIG. 6) that is perpendicular to the first direction (left-right direction in FIG. 6) in a plan view. It has an oblong external shape that is longer than the length (in the vertical direction). 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 a horizontally elongated shape, 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 a synthetic resin such as polyethylene, polypropylene, or polyethylene terephthalate, 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 leg 32, a plurality of short legs 33 (for example, four) shorter than the long leg 32 are provided so as to protrude downward from the side surface portion 31. The plurality of short legs 33 allows the support 3 to be placed substantially horizontally on the hand washing section with the long legs 32 inserted into the drain port of the hand washing section.

Further, the bottom portion 30 is provided with a substantially rectangular frame-shaped peripheral wall 34 that projects upward. An inner wall 41 of a cover member 4, which will be described later, is fitted into this peripheral wall 34. A notch 35 is formed at the upper end of the peripheral wall 34 by being cut out in a concave shape at positions facing each other. A through hole 36 is formed at the center of the area surrounded by the peripheral wall 34 of the bottom 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. 9 to 12, the cover member 4 includes an upper surface portion 40 having a substantially rectangular shape in plan view, an inner wall 41 having a substantially rectangular frame shape hanging from the upper surface portion 40, and an outer side of the inner wall 41. It includes an outer wall 42 that hangs down from the periphery of the upper surface part 40. By fitting the inner wall 41 inside the peripheral wall 34, the cover member 4 is installed on the bottom part 30, and a buffer chamber 6 is formed between the bottom part 30 and the cover member 4, as shown in FIG. be done. The buffer chamber 6 is a space in which a chemical solution can be stored.

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 part 40 is composed of a lower part 40a having a circular shape in plan view at the center thereof, and an upper part 40b around the lower part 40a located at a higher position than the lower part 40a. A cylindrical connecting member 44 that is inserted into the opening 21 of the liquid medicine container 2 is provided at the center of the lower part 40a. 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 .

A discharge member 45 that protrudes downward is provided at the lower stage portion 40a of the upper surface portion 40. The discharge member 45 has a cylindrical shape with a smaller diameter than the connection member 44, and is arranged concentrically with the connection member 44. The connecting member 44 and the discharge member 45 are in communication with each other, and the interiors of the connecting member 44 and the discharge member 45 constitute a liquid medicine passageway for passing the liquid medicine from the liquid medicine container 2 to the guide member 5, which will be described later. The inside of the discharge member 45 is partitioned off from the buffer chamber 6, and the discharge member 45 can be fitted into the through hole 36 located at the center of the bottom portion 30.

A plurality of small diameter liquid passage holes 46 (three in the illustrated example) are formed inside the connection member 44 and outside the discharge member 45 of the lower stage portion 40a. The liquid passage hole 46 introduces a portion of the liquid medicine discharged from the liquid medicine container 2 via the connecting member 44 into the buffer chamber 6 .

The buffer chamber 6 is for adjusting the amount of the chemical liquid discharged from the chemical liquid container 2 even when a pressure change occurs in the chemical liquid container 2 due to a temperature change. The buffer chamber 6 acts as follows with respect to temperature changes in the chemical solution container 2. For example, when the temperature rises and the chemical liquid container 2 is warmed, the air inside the chemical liquid container 2 expands and the inside of the chemical liquid container 2 becomes under positive pressure. In this case, the medicinal liquid in the medicinal liquid container 2 is pushed out and discharged from the mouth part 21, but the discharged medicinal liquid flows from the connecting member 44 and the discharge member 45 to the guide member 5, and also flows through the liquid passage hole 46. It also flows into the buffer chamber 6. Therefore, excessive flow of the chemical liquid into the guide member 5 is prevented.

On the other hand, when the temperature of the chemical liquid container 2 decreases by being cooled with running water, the air inside the chemical liquid container 2 contracts, and the pressure inside the chemical liquid container 2 becomes negative. In this case, the liquid medicine in 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 holes 46. It will be done. Therefore, the water or diluted medical solution on the guide member 5 is prevented from returning to the medical solution container 2 side through the discharge member 45 and the connecting member 44. Further, the discharge of the medical solution is prevented from being restricted by the negative pressure within the medical solution container 2.

As shown in FIGS. 1 to 3 and 5 to 8, the guide member 5 has a plate shape and protrudes downward from the bottom portion 30 so as to cross the through hole 36. As shown in FIGS. 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, the decoration 7 is housed in the liquid medicine container 2 together with the liquid medicine, thereby decorating the liquid medicine container 2 and improving the design of the liquid medicine supplying device 1. This improves the aesthetic appearance inside the toilet. The decorations 7 are sheet-like items made of, for example, non-woven fabrics or textiles made of natural fibers or synthetic resin fibers, or resin molded articles, and a plurality of decorations 7 are housed in the drug solution container 2 .

The decoration 7 may remain in the drug solution and float in 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, 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 decorations 7 are floating in the liquid medicine in the liquid medicine container 2, the decorative effect of the decorations 7 is increased, and the liquid medicine supply apparatus installed at eye level like the liquid medicine supply apparatus 1 of this embodiment is 1, since the decorations 7 inside the chemical liquid container 2 are clearly visible when the chemical liquid supply device 1 is viewed straight, the design of the chemical liquid supply device 1 can be favorably improved.

When the decoration 7 is floating on the liquid level of the liquid medicine in the liquid medicine container 2, the decoration 7 moves up and down in the liquid medicine liquid container 2 along with the liquid level of the liquid medicine, so check the position of the decoration 7 in the liquid medicine container 2. By doing so, the remaining amount of the drug solution in the drug solution container 2 can be easily grasped. In addition, when looking down on the chemical solution supply device 1 installed on the floor, the decorations 7 inside the drug solution container 2 are easily visible because they are floating above the drug solution container 2. Therefore, the design of the chemical liquid supply device 1 can be favorably improved.

If the decoration 7 is submerged at the bottom of the chemical solution in the drug solution container 2, the decoration 7 will not be maintained at the bottom of the drug solution container 2 when expressing, for example, a flower submerged in water or the seabed. Therefore, the above-mentioned world view can be well expressed, and the design of the chemical liquid supply device 1 can be well improved.

As a method for floating the decoration 7 in the chemical solution in the chemical solution container 2, for example, the specific gravity of the decoration 7 when dry is made equal to the specific gravity of the drug solution. Here, "having the same specific gravity" means that the specific gravity of the decoration 7 and the chemical solution are the same, or even 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 7 can be, for example, within a range of 0.9 times or more and 1.1 times or less of the specific gravity of the chemical solution.

As a method for floating the decoration 7 on the surface of the medicinal solution in the medicinal solution container 2, for example, the specific gravity of the decoration 7 when dried is made smaller than the specific gravity of the medicinal solution. Here, the term "specific gravity is small" means that the specific gravity of the decorative object 7 is smaller than the specific gravity of the chemical solution, so that the decorative object 7 stands out, and the specific gravity of the decorative object 7 is, for example, less than 0.9 times the specific gravity of the chemical solution. Can be made smaller.

An example of a method for causing the decoration 7 to sink below the medicinal solution in the medicinal solution container 2 is to make the specific gravity of the decoration 7 when dry larger than the specific gravity of the medicinal solution. Here, the expression "high specific gravity" means that the specific gravity of the decoration 7 is greater than the specific gravity of the chemical solution as the decoration 7 sinks, and the specific gravity of the decoration 7 is, for example, more than 1.1 times the specific gravity of the chemical solution. Can be made larger.

The specific gravity of the above-mentioned chemical solution can be measured at room temperature (25° C.) using a standard hydrometer (1-5659 (small size), manufactured by Nippon Keizai Kogyo Co., Ltd.). For example, when the specific gravity of the chemical solution is 0.94 to 1.00, No. 5, and No. 5 when the specific gravity is 1.00 to 1.06. 6, and when it is 1.06 to 1.12, it is No. 7, and when it is 1.12 to 1.18, it is No. 8, and when it is 1.18 to 1.24, it is No. 9, and when it is 1.24 to 1.28, it is No. Ten hydrometers are used each. Specifically, put 100ml of chemical solution into a measuring cylinder with a capacity of 100ml, float the hydrometer in the chemical solution, and with the hydrometer floating stably, measure the value at the intersection of the liquid level and the black line on the hydrometer. Measure specific gravity by reading.

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 liquid. 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 levitation, floating, etc.) (or sedimentation 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.

Note that the decoration 7 does not necessarily have to have the property of not substantially absorbing the medicinal solution, but may have the property of absorbing the medicinal solution. In this case, in a dry state, the decoration 7 has a specific gravity smaller than that of the chemical and floats on the surface of the chemical, but by absorbing the chemical, the decoration 7 floats in the chemical or floats to the bottom of the chemical. You may start to sink. Further, in a dry state, the decoration 7 has a specific gravity equal to that of the chemical and floats in the chemical, but by absorbing the chemical, the decoration 7 may sink to the bottom of the chemical.

As shown in FIG. 13, the decoration 7 includes a base 70 located at the center and a plurality of (four in the illustrated example) extensions 71 located around the base 70. The plurality of extension parts 71 are radially connected to the base 70 with the base 70 as the center in a plan view, and are arranged around the base 70 at equal intervals. In the example shown in FIG. 13, the number of extensions 71 is four, and the four extensions 71 are located around the base 70 at 90° intervals.

Note that the number of extension parts 71 is not particularly limited, and as shown in FIG. If there are three extensions 71, the three extensions 71 are located at 120° intervals around the base 70, and if there are five extensions 71, the five extensions 71 are located around the base 70. located at 72° intervals around the Note that the plurality of extension parts 71 do not necessarily have to be arranged at equal intervals, and the intervals may be different, or there may be no interval (a gap between two adjacent extension parts 71). Good too.

As shown in the example shown in FIG. 13, each extending portion 71 may have a curved shape or a linear shape in which the end edges on both sides gradually widen toward the distal end edge on the opposite side from the base portion 70. It may have a curved shape or a straight line shape that gradually narrows toward the edge, or it may have a curved shape or a straight line shape in which the edges on both sides are parallel to each other. The tip edge of each extending portion 71 may have a long curved shape or a straight line, as in the example shown in FIG. 13, or may be pointed. The shape of the decoration 7 is not particularly limited, but examples include those resembling flowers, clovers, stars, starfish, etc. When the decoration 7 imitates a flower, for example, In this case, each extending portion 71 imitates a flower petal, and when the ornament 7 imitates a clover, each extending portion 71 imitates a leaf. In addition, in this embodiment, the decoration 7 imitates a flower.

The decoration 7 is a three-dimensional object that is given height as well as a planar extent by bending a part of the sheet. Specifically, in the decoration 7, at least a portion of each extending portion 71 on the tip side is bent in the vertical direction. In other words, as shown in FIGS. 13(B) and 14(A), even if the entire extending portion 71 is bent in the vertical direction with respect to the base 70 at the boundary with the base 70, each extending portion 71 is Alternatively, as shown in FIG. 14(B), a part of the extending part 71 on the base 70 side is flat or substantially flat with the base 70, and a part of the extending part 71 on the distal end side opposite to the base 70 is connected to the base 70 in a flat or almost flat manner. Only the portion may be bent in the vertical direction with respect to a portion on the base portion 70 side.

Further, each extending portion 71 of the decoration 7 is bent in the opposite direction from the extending portion 71 adjacent to at least one of both sides of the base 70 in the circumferential direction (hereinafter simply referred to as the “circumferential direction”). . In other words, each extension part 71 may be bent in the vertically opposite direction to either of the two extension parts 71 located on both sides, or the two extension parts 71 located on both sides may be bent in the opposite direction. For either one of them, the direction of bending may be in the opposite direction, but for the other, the direction of bending may be the same.

In this embodiment, the plurality of extending portions 71 arranged in the circumferential direction are basically bent vertically in opposite directions, that is, from a predetermined extending portion 71 serving as a starting point to a point in the circumferential direction. The extending portions 71 are alternately bent in opposite directions up and down to the end point extending portion 71 adjacent to the predetermined extending portion 71 on the other side in the circumferential direction, and are bent upward. The extending portions 71 and the downwardly bent extending portions 71 are arranged alternately in the circumferential direction.

In addition, as shown in FIG. 13(B) and FIG. 15(A), in the decoration 7 in which the number of extending portions 71 is an even number (four in FIG. 13(B) and two in FIG. 15(A)), , all of the plurality of extensions 71 are alternately bent in opposite directions. On the other hand, as shown in FIG. 15(B) and FIG. 15(C), the decoration 7 has an odd number of extending portions 71 (three in FIG. 15(B) and five in FIG. 15(C)). In this case, the plurality of extension parts 71 are alternately bent vertically in opposite directions except between the pair of adjacent extension parts 71 at the start point and the end point. Adjacent extension parts 71 are bent in the same direction up and down, and the extension parts 71 bent in the same direction up and down are continuous.

When a plurality of sheet-like decorations 7 are stored in the drug solution container 2, the plurality of sheet-like decorations 7 may be disposed of due to the flow of the drug solution in the process of reducing the amount of the drug solution in the drug solution container 2 as the drug solution supply device 1 is used. The decorations 7 may move and some decorations 7 may cover other decorations 7. At this time, if the decorations 7 are in the form of a flat sheet, there is a risk that the two overlapping decorations 7 will overlap and appear as one, making it impossible to visually recognize that there are multiple decorations 7. There is a risk that the design quality may deteriorate.

On the other hand, as shown in FIG. 16, in the present embodiment, the two circumferentially adjacent extensions 71 of the decoration 7 are bent in opposite directions, so the two overlapping decorations 7 are The extension parts 71 are bent toward each other so that they contact each other with a gap, and the other extension parts 71 are bent away from each other so that they are spaced apart without coming into contact with each other. state. In this way, by forming the decorations 7 in a three-dimensional shape, even if the decorations 7 overlap each other, they are prevented from completely overlapping. Furthermore, when the number of extensions 71 is different, overlapping is further suppressed, and in particular, when the number of extensions 71 is an even number and an odd number, the suppression effect is even higher. Therefore, it is possible to prevent the two overlapping decorations 7 from appearing as one and not being able to visually recognize that there are a plurality of decorations 7, so that deterioration in the design of the chemical solution supply device 1 can be suppressed.

In addition, when the decoration 7 housed in the chemical liquid container 2 sinks below the chemical liquid, or when the decoration 7 settles due to the decrease in the chemical liquid in the chemical liquid container 2 due to use, the discharge port 2 of the chemical liquid container 2 If the decoration 7 covers the discharge port 22, if the decoration 7 is in the form of a flat sheet, the discharge port 22 may be covered and blocked by the decoration 7, and the discharge of the medicinal solution from the discharge port 22 may be inhibited. .

On the other hand, as shown in FIG. 17, in the present embodiment, the two extensions 71 adjacent to each other in the circumferential direction of the decoration 7 are bent in vertically opposite directions. , it becomes easier to stand on the bottom of the drug solution container 2, and the possibility that the extension portion 71 is placed over the discharge port 22 is reduced. Therefore, a gap is likely to be formed between the decoration 7 and the discharge port 22. In this way, by forming the decoration 7 in a three-dimensional shape, even if the decoration 7 covers the discharge port 22, it is suppressed from completely blocking the discharge port 2. Furthermore, even when another decoration 7 covers the decoration 7, a gap is formed between the decoration 7 and the decoration 7 stacked above due to the upwardly bent extending portion 71. Therefore, the medicinal liquid in the medicinal liquid container 2 can be well discharged from the ejection port 22 to the outside of the medicinal liquid container 2 through the gaps between the decorations 7 and the gaps between the decorations 7 and the ejection port 22.

Note that, as shown in FIG. 18(A), the decoration 7 has a portion on the inside where the periphery of the discharge port 22 fits completely even when the extending portion 71 is placed over the discharge port 22 of the liquid medicine container 2 in a plan view. It is preferable to make the size so that it is not included. Thereby, even if each extending portion 71 of the decoration 7 covers the outlet 22, a gap G can be created between the periphery of the outlet 22 and each extending portion 71 of the ornament 7. , the chemical liquid can be smoothly guided to the ejection port 22 through the gap G without blocking the ejection port 22, and the chemical liquid can be smoothly supplied.

The size of the decoration 7 is determined so that the size of the decoration 7 is determined by the size of the discharge port of the drug solution container 2 when it sinks below the drug solution in the drug solution container 2 or when it settles in the drug solution container 2 due to the decrease in the amount of drug solution due to the use of the drug solution supply device 1. It is preferable that the size is such that it does not pass through 22. Specifically, as shown in FIG. 18(B), by making the diameter R1 of a virtual circle (circle circumscribing the decoration 7) C that includes the decoration 7 larger than the diameter R2 of the discharge port 22, the chemical liquid The decoration 7 in the container 2 can be prevented from passing through the discharge port 22 and coming out of the liquid medicine container 2.

It is preferable that the plurality of ornaments 7 housed in the chemical liquid container 2 are color-coded using at least two colors. Thereby, it is possible to more clearly visually recognize that there are a plurality of overlapping decorations 7 in different colors. Moreover, by having different colors, when the colors of the decorations are reflected in the medicinal solution, the colors mix together, which further improves the aesthetic appearance.

Although the color-coding method is not particularly limited, it is possible to color-code multiple types of decorations 7 having different numbers of extensions 71. For example, when a plurality of decorations 7 are composed of two types of decorations 7 having different numbers of extensions 71, two colors are used to give different colors to each type of decorations 7. . When the plurality of decorations 7 are composed of three types of decorations 7 having different numbers of extensions 71, each type of decoration 7 is given a different color using three colors. Alternatively, two colors may be used, so that decorations 7 of types with a similar number of extensions 71 are given different colors, and decorations 7 of types with a far number of extensions 71 are given different colors. Or you can give them the same color. Specifically, for example, three types of decorations 7 having 3 to 5 extensions 71 are exemplified.A decoration 7 having three extensions 71 is different from a decoration 7 having four extensions 71. The decorations 7 with four extensions 71 and the decorations 7 with five extensions 71 are given different colors, and the decorations 7 with three extensions 71 and the decorations 7 with extensions 71 are colored differently. It may be given the same color that is different from the five decorations 7, or it may be given the same color. Note that even if the decorations 7 of the same type have the same number of extensions 71, it is possible to color code them.

The method of coloring the decorations 7 with different colors may be such that the entire decoration 7 is colored in a different color, or at least each of the extensions 71 is painted in a different color, and furthermore, at least each of the extensions 71 is colored in a different color. A part of the tip side may be a different color. Alternatively, the colors may be different shades of the same color.

A method of folding the sheet described above to form the three-dimensional decoration 7 is to punch out a sheet of non-woven fabric or the like into a predetermined shape (a flower shape in this embodiment) using a mold, and then punch the punched sheet with a mold. An example of a method is to bend the sheet into a desired three-dimensional shape by sandwiching it from both sides and pressing it while applying heat. 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.

According to the chemical solution supply device 1 of the present embodiment described above, since the decoration 7 is housed together with the drug in the drug solution container 2 whose interior is visible, the decorative effect of the decoration 7 improves the design of the drug solution supply device 1 itself. will improve. Therefore, for example, when the chemical solution supply device 1 is installed in the hand washing section above the water storage tank of a flush toilet, the aesthetic appearance of the inside of the toilet can be improved even if there is no other decoration for the hand washing section. Therefore, it is sufficient to secure the same amount of space in the hand-washing section as the conventional drug supply device, and there is no need for a large space in the hand-washing section for decoration. Moreover, since the various openings 37A, 37B formed in the chemical solution supply device 1 and the drain port of the hand washing section are not blocked, the desired effect of the drug solution supply device 1 can be obtained.

Moreover, since the plurality of decorations 7 housed in the liquid medicine container 2 have a three-dimensional shape in which the two extending parts 71 adjacent to each other in the circumferential direction are bent in opposite directions, for example, Even if two decorations 7 are covered, the overlapping decorations 7 are prevented from completely overlapping, and it can be seen at a glance that one decoration 7 is placed on top of the other decoration 7. . Therefore, it is possible to prevent the plurality of overlapping decorations 7 from appearing as one and not being able to visually recognize that there are a plurality of decorations 7, and thus it is possible to suppress deterioration in the design of the chemical liquid supply device 1.

In addition, even if the decoration 7 covers the discharge port 22 in the liquid medicine container 2, a gap is created between the discharge port 22 and the decoration 7. Furthermore, even if a plurality of decorations 7 are placed over the discharge port 22, gaps will be formed between the decorations 7. Therefore, the medicinal solution in the medicinal solution container 2 is 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 discharge port 22. Therefore, the decorations 7 in the liquid medicine container 2 are prevented from obstructing the discharge of the liquid medicine from the discharge port 22, and the supply of the liquid medicine can be carried out smoothly.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention.

In the embodiment described above, the plurality of extensions 71 arranged in the circumferential direction of the decoration 7 are basically bent alternately in opposite directions, but are not necessarily bent in opposite directions vertically. It is not necessary, and as shown in FIG. 19, the direction in which only one of the two extending portions 71 adjacent to each other is bent may be vertically opposite.

In the above embodiment, among the on-tank type chemical solution supply devices installed in the hand washing section above the water storage tank of a flush toilet, a type of chemical solution supplying device by inserting the guide member 5 into the drain port of the hand washing section is exemplified. Although the present invention has been described, the present invention can also be suitably applied to various types of chemical solution supply devices, such as a type that directly supplies a chemical solution to a hand washing section.

In addition, in the above embodiment, an on-tank type chemical solution supply device installed in the hand washing section above the water storage tank of a flush toilet is described as an example, but a chemical solution supply device of a type that is hung on the rim of the toilet bowl is used. The present invention can also be suitably applied to the supply device.

In addition, in the above embodiment, a chemical solution supply device for a flush toilet is described as an example, but it can be placed on the floor or shelf of a room such as a living room or entrance to volatilize or deodorize an indoor space. The present invention can also be suitably applied to a type of chemical liquid supply device that supplies chemical liquid by evaporation or the like.
