Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drug elution device for preventing urine stones from sticking to a urinal, for example.

[0002]

2. Description of the Related Art Conventionally, a liquid such as urine or washing water (hereinafter, urine is described as a typical example, is generally referred to as liquid by providing a spud having a slit or the like at the drainage port of a urinal. The drainage port is concealed while maintaining the drainage amount.

Around the drainage port of such a urinal and the drainage route to this drainage hole, etc., urine stones containing calcium or the like as a main component contained in urine easily adhere and solidify, This impairs the aesthetics of the urinal and causes a foul odor.

Therefore, in order to prevent such urine stones from sticking in the urinal, a solid urinary stone sticking preventing agent is mainly installed directly in the vicinity of the drainage hole, or the agent is put in a container. Place this drug in contact with urine,
It is common to dissolve urinary stone components and discharge them.

However, when the drug for preventing urinary stone sticking is installed near the drain of the urinal, the drug or the drug storage container is in a state of protruding from the inner bottom surface of the urinal. When urine is released into the urine, the urine that has come into contact with the medicine and the medicine container is scattered outside the urinal, which easily contaminates the floor surface of the toilet in which the urinal is installed.

As a result, the floor of the toilet becomes unfavorable in terms of hygiene, and in order to maintain the hygiene, it is necessary to frequently clean the floor contacted with urine, which increases the burden of cleaning the toilet. .

[0007]. Therefore, in order to prevent the urine that has come into contact with the drug storage container from splashing out of the urinal and to maintain a hygienic condition, a lid is provided on the upper part of the drug storage container, and this lid is radially radiated from its center. Patented is a drug elution device for preventing urinary stone fixation, which is formed by forming a plurality of standing plate parts and forming through holes through which urine passes between the standing plate parts to guide the urine to the drug side. No. 2,678,543.

In this elution device, the urine that has come into contact with the side surface of the standing plate portion formed on the lid for guiding the liquid is guided to the medicine container while being bounced between the standing plate portions, and this guided urine is guided. After contact with the drug, let it flow into the drain of the urinal.

In order to fix the drug eluting device to the inner bottom of the urinal, a spud (or a trap lid) is attached around the drain of the urinal so that its peripheral edge is in close contact with the inner wall of the urinal.

[0010]

However, in the above-mentioned drug elution device, since the standing plate portion is arranged radially around the center of the liquid guiding lid, the standing plate portion and the standing plate portion are arranged. The liquid passage holes between them have the same size all around the entire circumference of the lid, and when installed in a urinal, the urine reception or I cannot give enough guidance.

Further, since the standing plate portion is radially formed with the center of the lid body as the center, the dimension and arrangement of the standing plate portion are strict when molding the lid body including the standing plate portion. Therefore, the degree of freedom in designing the lid becomes poor, and it is necessary to maintain the molding accuracy of the lid.

The present invention has been made in view of the above situation, and an object thereof is to guide a liquid reliably and efficiently through a passage hole for guiding a liquid of a lid portion and to provide a sufficient medicine. The object of the present invention is to provide a drug eluting device that can be brought into contact with the skin and improve the degree of freedom in designing the lid portion.

[0013]

[Means for Solving the Problems] That is, the present invention comprises a drug container for containing a drug and a lid part connected to the drug container, and a plurality of standing plate parts are provided on the lid part. Radially provided, these standing plate portions form a passage hole for guiding a liquid, the liquid is brought into contact with the medicine in the medicine container via the passage hole, and the plurality of standing plates are provided. The present invention relates to a drug eluting device in which a radiation center of a plate portion is arranged so as to be deviated from a center of the lid body portion.

According to the present invention, the radial centers of the plurality of standing plate portions are arranged so as to be deviated from the center of the lid portion, so that the liquid guide passages formed by these standing plate portions are provided. Since the sizes of the holes are different in the circumferential direction of the lid portion and the liquid receiving or guiding amount is different between the respective passing holes, a large amount of liquid is passed through the standing plate portion having the passing holes having a large liquid receiving or guiding amount. It can be arranged on the inflow side (especially on the front side), which ensures and efficient reception and guidance of the liquid and sufficient contact with the drug.

Further, when designing the lid portion, the radiation center of the standing plate portion can be set at an arbitrary position at a position deviated from the center of the lid portion, so that the design is free. Therefore, the lid portion can be easily molded.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, in order to more reliably receive a liquid and bring it into rapid contact with a drug, the lid body portion has a standing plate portion on the outer peripheral side and a height lower than this. If the liquid is collected in the concave portion formed by the inner standing plate portion and the inner standing plate portion, since the height of this concave portion is low, the distance to the lower drug is small. It becomes short and the liquid can be efficiently collected and brought into quick contact with the drug.

Further, from the above, the liquid receiving areas between the standing plate portions are different in the circumferential direction of the lid portion, and the side having the larger liquid receiving area is directed to the front where a large amount of liquid easily flows. Is desirable.

Further, it is desirable that this drug elution device is attached to a trap body (trap lid) attached to the drainage port of the toilet bowl.

Preferred embodiments of the present invention will be described below in detail with reference to the drawings.

In the present embodiment, as shown in FIGS. 1 to 5, the drug elution device 15 is mainly composed of a liquid guiding lid part 2 and a drug containing part 7 connected thereto. There is.

As shown in FIG. 5, the medicine container 7 is
A liquid such as urine or washing water (hereinafter, urine will be described as a typical example) through a plurality of passage holes 28 provided on the side surface and the bottom surface of the basket-shaped portion for containing the urinary stones fixing agent 6 (see FIG. 2). ), The drug 6 that has melted out flows out. Further, the ring-shaped flange protruding outward is provided with, for example, three inverted L-shaped projections 10 for connecting the medicine containing portion 7 to the lid portion 2, for example.

As shown in FIG. 2, the projection 10 is elastically fitted into the mounting portion 9 provided on the substantially circular lid portion 2 arranged so as to cover the opening portion 24 from the opening 24. By doing so, the lid body part 2 is connected to the medicine containing part 7, and the medicine containing part 7 and the lid part 2 are integrated.

Next, as shown in FIGS. 1 to 3, the lid portion 2 integrally has a standing plate portion 1 for guiding liquid. The standing plate portions 1 are arranged in the circumferential direction of the lid body portion 2 and are provided radially in a petal shape as a whole, and the intervals between the standing plate portions are different in the circumferential direction of the lid body portion 2, Moreover, the lengths of the standing plate portions also change in the radial direction.

Specifically, when it is attached to the toilet bowl,
The rib-shaped standing plate portion 1a directed forward has the maximum spacing and length, and the rib-shaped standing plate portion 1c directed rearward has the minimum spacing and length, and is directed from these standing plate portions 1a to 1c. The intervals and lengths are gradually decreasing in the circumferential direction. Further, the rib-shaped standing plate portion 1b having a low height is also provided in the central portion of the lid portion 2.
Are also provided radially in common with the standing plate portions 1a and 1c in a state of being radiated in common, but as shown in FIGS. 2 and 3, a concave portion 3 is formed in the central portion of the lid portion 2. There is.
Liquid passage holes 8a, 8b, and 8c for urine or the like are formed between the standing plate portions, and the size, width, and length of the liquid passage holes from the standing plate portions 1a to 1c are 8a. 8c
It is getting smaller and smaller.

Further, in the respective passage holes 8a, 8b and 8c formed between the standing plate portions in the standing plate portion 1 including the standing plate portions 1a, 1b and 1c, the discharged urine 11 is discharged.
However, the medicine accommodating portion 7 that accommodates the medicine 6 while directly entering the passage holes 8a, 8b and 8c or being reflected by coming into contact with the side surface portions of the respective standing plate portions 1a, 1b and 1c, etc.
The urine 11 is efficiently guided toward the medicine container 7 without bouncing back to the outside of the urinal 16 (see FIGS. 7 and 8) because the urine 11 flows out toward each side toward the medicine container 7.

After that, the urine 11 that has flowed out comes into contact with the drug 6 for preventing urinary stone fixation contained in the container 7, so that the urine component in the urine is dissolved by the drug 6 and stored in the urinal 16. From the plurality of passage holes 28 provided on the bottom surface and the side surface of the housing portion 7 without being fixed, the drain port portion 20 (see FIG. 7).
Flows into.

As shown in FIG. 2, a recess 3 is formed mainly by the standing plate 1b in the central portion of the liquid guide lid 2, and the passage hole 8b of the recess 3 is formed. The liquid receiving area is smaller than the liquid receiving areas of the passage holes 8a and 8c formed by the other standing plate portions 1a and 1c, and
The height of the standing plate portion 1b is lower than the height of the other standing plate portions 1a and 1c.

Therefore, since the liquid receiving area of the passage hole 8b is relatively small as compared with the liquid receiving area of the passage holes 8a and 8c, the urine 11 is temporarily collected in the concave portion 3, but the standing plate. Since the height of the portion 1b is lower than the heights of the standing plate portions 1a and 1c, and the collection position of the urine 11 is closer to the lower urinary stones-preventing drug 6, the urine 11 can be efficiently collected in the recess 3. Instead, the collected urine 11 relatively quickly and surely passes through the passage hole 8b and comes into sufficient contact with the drug 6 in the drug container 7 from the entire upper surface thereof.
In addition, the presence of the concave portion 3 also reduces bounce of urine.

Further, when the cleaning water for cleaning the urinal comes into contact with the cleaning water, the cleaning water can be sufficiently guided through the passage holes 8a and 8b to effectively contact the surface to be cleaned. In addition to this, the standing plate portion 1b having the passage hole 8b
Since the washing water is temporarily collected due to the presence of the concave portion 3 at the portion (3), the washing water is in contact with the passage hole 8b for a longer time, and it is easy to maintain the sanitary condition in the urinal.

In this embodiment, it should be noted that, as shown in FIG. 1 (b), the rib-shaped standing plate with respect to the center 22 of the lid body portion 2 is located on the diameter line of the circular lid body portion 2. The radiation center 23 of the part 1 is displaced by the distance d. For example, since the distance d is set to 5 mm and the radiation center 23 is considerably displaced from the lid body center 22, the shapes of the standing plate portions 1a, 1b and 1c are different from each other as described above. Standing plate portions 1a, 1b and 1c
The liquid receiving areas corresponding to the sizes of the passage holes 8a, 8b and 8c formed by are also different.

Therefore, as shown in FIGS. 6 to 8, of the liquid passage holes, the larger (or maximum) width is W and the length g.
The passage hole 8a of the urine 11 toward the discharge side (front side) of the urine 11 to the urinal with which the urine 11 contacts more, and the passage of the smaller (or minimum) width t or T and the length f. Hole 8c
Urine by placing the urinal on the back (rear) side of the urinal.
It is possible to increase the receiving area of the passage hole in the portion where 1 contacts more and to send the urine 11 more efficiently and reliably to the medicine container 7 in the lower portion of the passage hole.

In the present embodiment, the distance d is set to, for example, 5 mm, but this is not a dimensional tolerance (error) in molding but is positively provided in order to realize the above-described action and effect. Yes, for example, a lid portion 2 for guiding liquid
When the outer diameter h is 70 mm, the dimensional tolerance in molding is 0.1% = 0.07 mm, but the distance d (5 mm) is much larger than this.

As an example, the size of each part is h = 8
0 mm, W = 6.28 mm, g = 23 mm, T = 4.2
1 mm, t = 2.93 mm, f = 10 mm and d = 5 m
It may be m. The dimensional tolerance at this time is 0.08 mm, and the distance d, which is the deviation of the radiation center, is much larger than the dimensional tolerance.

Next, when the distance d from the center 22 of the liquid guiding lid portion 2 to the radial center 23 of the standing plate portion 1 is 5 mm, the standing plate portions 1a, 1b and 1c are connected. In the liquid guiding lid portion 2 as described above, as shown in FIG. 4A, the height of the standing plate portion 1a at the outer peripheral portion is the same as the height of 1c, but, for example, in FIG. As shown, the standing plate 1a
May be lower than the height of 1c by a distance e.

As described above, as the height of the rib-shaped standing plate portion 1a with which a large amount of urine 11 comes into contact is lowered by the predetermined distance e, the height of the standing plate portion 1a forming the passage hole 8a is increased. Since it becomes smaller and the upper surface of the lid body 2 is inclined to the front to some extent as a whole, it becomes easier to receive the discharged urine. However, if the distance e is made too large, the standing plate portion 1a becomes too low, and the function of the standing plate portion 1a as the reflection plate of the urine 11 deteriorates accordingly, so the value of e is appropriate. Must be kept at.

Further, on the bottom surface of the lid portion 2 composed of the standing plate portions 1a, 1b and 1c, the lid portion 2 for guiding the liquid and the medicine accommodating portion 7 are provided by the attaching portion 9 and the inverted L-shaped projection portion 10. As shown in FIG. 2, a bottom surface concave portion 5 is provided on the bottom surface of the lid portion 2 to facilitate connection with the work space. Is secured, and it becomes easy to fit the protrusion 10 of the medicine container 7 into the attachment 9 of the lid 2.

In the medicine eluting device 15 according to the present embodiment, the lid portion 2 has the above-described standing plate portions 1a, 1b,
1c has a unique petal-like appearance as a whole, and it is also the appearance that the radiating centers are deviated so that the standing plates 1a and 1c of different sizes have different sizes in the circumferential direction. Is more unique.

As shown in FIG. 6, FIG. 7 and FIG. 8, the trap lid 13 is attached to the drainage port 20 on the inner bottom surface of the urinal 16 almost horizontally.
A flat plate part 14 having a shape corresponding to 0, and having an opening 12 for fitting the drug containing part 7 of the drug eluting device 15 to communicate the lid part 2 and the drainage port part 20; The lower surface of the portion 14 is composed of a mounting leg portion 17 provided integrally with the flat plate portion 14.

Here, when the trap lid 13 is attached to a predetermined portion of the urinal 16, the peripheral portion 25 of the flat plate portion 14 is in close contact with the inner wall surface of the upper end of the drainage port portion 20. The urine 11 or the wash water released in 16
Without leaking between the peripheral portion 25 of the trap lid 13 and the urinal 16, the passage holes 8a, 8b of the drug eluting device 15 are provided.
Drainage port 20 through 8c and 28 and opening 12
Smoothly flows into.

Further, since the mounting leg portion 17 is securely fixed by being fitted to the outside of the drain pipe 21 in the drainage port portion 20 of the urinal, it is temporarily drained by the flowing urine 11 and washing water. Even if the water level in the mouth portion 20 rises, the water pressure causes the trap lid 13 not to float, and the urine 11 or washing water flows into the drain pipe 21 through the passage 18 of the drain outlet portion 20.

In this trap lid 13, the opening 1
By attaching the drug eluting device 15 having a size corresponding to the size of No. 2, the device 15 can be fixed to the toilet without changing the shape of the conventional trap lid, etc. In addition, the increase in cost is reduced and the cost is relatively low.

As described above, according to this embodiment,
Since the radial centers 23 of the rib-shaped standing plate portions 1 are arranged deviated from the center 22 of the guide lid portion 2 such as urine, the urine formed by these standing plate portions 1 is arranged. The passage holes 11 for guiding 11 and the like are different in the circumferential direction like 8a and 8b, and the passage amounts of the passage holes 8a, 8b and 8c are different from each other. The passage hole 8a having a larger guide amount can be arranged on the side (the front side) where a greater amount of contact with the lid body portion 2 occurs.
It is possible to efficiently and reliably guide the urine stone preventing chemical 6 by reducing the rebound of the urine 11 and the like coming into contact with the urine.

Further, when designing the lid portion 2, the radiation center 23 can be selectively set at an arbitrary position with respect to the center 22 on the diameter line of the lid portion 2, so that the degree of freedom in design is increased. In addition, the allowable range of molding precision when molding with plastic or the like is expanded.

When mounting the drug eluting device 15 on the urinal 16, it is sufficient to fit the drug container 7 of the drug eluting device 15 into the opening 12 of the trap lid 13.
Can be easily installed.

Further, since the central portion of the lid portion 2 forms the concave portion 3 due to the standing plate portion 1c having a low height, the urine 11 is easily collected in the concave portion 3 and the urine 11 is stored outside the urinal 16. Difficult to scatter.

The embodiment described above can be further modified based on the technical idea of the present invention.

For example, the position of the radial center of the rib-shaped standing plate portion 1 with respect to the center of the lid portion 2 may be changed variously, and their size, shape, material, etc. can be changed. The same applies to the drug container 7 and other parts.

Further, the above-mentioned drug elution device may be applied to, for example, indoor fountains. For example, even if the discharged fountain liquid is received and brought into contact with the above-mentioned drug, treatment with the drug is performed. Good.

[0049]

As described above, according to the present invention,
By arranging the radial centers of the plurality of standing plate portions so as to be displaced with respect to the center of the lid body portion, the size of the liquid guide passage holes formed by these standing plate portions can be made larger than that of the lid body portion. Different in the circumferential direction, the liquid receiving or guiding amount differs in each passage hole. Therefore, the standing plate portion having the passing hole with a large liquid receiving or guiding amount is placed on the side (especially the front side) where a large amount of liquid flows. It can be placed so that it can reliably and efficiently receive and guide the liquid and have sufficient contact with the drug.

Further, in designing the lid portion, if the position is deviated from the center of the lid portion, the radiation center of the standing plate portion can be set at an arbitrary position, so that the design is free. Therefore, the lid portion can be easily molded.
