JP, 2008-248521, A Japanese Patent Publication No. 2017-526839

In the medicine supply tools of Patent Documents 1 and 2, since the opening exists in a wide height region extending from the upper part to the lower part of the container part, the wash water easily flows directly into the container part from the opening of the container part at the time of washing with water, The following problems occur depending on the specifications of the flush toilet (method of flowing flush water).

As shown in FIG. 7, the specifications of the flush toilet (method for flushing water) include so-called direct type (FIG. (a)), so-called semi-tornado type (FIG. (b)), so-called tornado type (FIG. 7). (C)}. The direct type is a method in which wash water is jetted directly downward along the inner surface of the toilet from a number of outlets provided along the upper edge of the toilet, while the half-tornado type is installed along the upper edge of the toilet. The tornado type is a system in which wash water is jetted obliquely downward along the inner surface of the toilet from each of a number of jet outlets. The tornado type is one outlet provided on the inner side of the upper edge of the toilet, and the wash water is horizontal along the inner surface of the toilet bowl. It is a method of ejecting in the direction.

In the direct type or semi-tornado type flush toilet, the amount of flush water ejected from each ejection port varies. Therefore, when the chemical supply tool as in Patent Documents 1 and 2 is used for a direct type or semi-tornado type flush toilet, the amount of flush water flowing into the inside of the container through the opening and coming into contact with the chemical is a portion of the chemical. The amount of the drug eluted into the wash water varies among the parts of the drug (elution variation). Then, due to this variation in elution, the degree of consumption of the drug varies from site to site. On the other hand, in order to ensure the desired functions such as cleaning, disinfection, deodorization, and aroma imparting, the concentration of the components of the drug supplied to the toilet bowl during one flush (during flushing) (the water accumulated in the toilet bowl after flushing) It is necessary to increase the drug component concentration of the drug to a certain level or more, but if a part of the drug is greatly consumed or disappears, the drug elution amount decreases as a whole, and the drug component concentration supplied to the toilet bowl becomes insufficient. As a result, the desired function cannot be obtained. Therefore, there is a problem that it is necessary to replace the drug in the container portion with a new drug relatively early, and the usable period of the drug (usable flush frequency) is reduced.

In addition, when the chemical supply device as in Patent Documents 1 and 2 is used in a tornado-type flush toilet bowl, the chemical agent in the container portion comes into contact with a large amount of flush water that horizontally swirls along the inner surface of the toilet bowl. However, there is a problem in that the drug is consumed quickly due to excessive elution, and the usable period of the drug (the usable number of flushes) is reduced.

In view of the above-mentioned problems in the prior art, the present invention can ensure a certain usable period (usable number of flushes) regardless of the specifications of the flush toilet, with little variation in dissolution or excessive dissolution of the drug in the container portion. An object is to provide a drug supply tool.

In order to solve the above-mentioned problems, the present invention is a medicine supply tool which is used by being hung on a rim of a flush toilet, and which contains a solid, semi-solid or gel medicine inside, and a flush water. Is provided with a container portion having an opening through which the inside can pass, the opening is provided in the lower portion of the container portion, and the container portion is a drug supply tool in which a portion above the opening is closed to the outside. provide.

According to the present invention, regardless of the specifications of the flush toilet, it is possible to provide a medicine supply tool that can secure a certain usable period (usable number of flushes) with little variation or excessive dissolution of the medicine in the container. ..

In this embodiment, the container part 1 is formed in an elongated cylindrical shape, is hung on the edge of the toilet with the hanging device 3, and the longitudinal centerline L is oriented horizontally along the inner surface of the toilet. Will be placed. The receiving part 2 is formed in an elongated saucer shape along the longitudinal line L of the container part 1 and is detachably attached to the lower part of the container part 1.

2 (cross section orthogonal to the longitudinal centerline L: corresponding to the AA cross section in FIG. 4), FIG. 3 (cross section orthogonal to the longitudinal centerline L: corresponding to the BB cross section in FIG. 4), and FIG. As shown in, in this embodiment, the container portion 1 is composed of an upper container 1A and a lower container 1B, and the upper container 1A and the lower container 1B are detachably fitted to each other at a fitting portion F. In the lower part of the lower container 1B, the above-mentioned opening 1a, a slender lower opening 1b along the longitudinal centerline L, and a pedestal 1c (1c1, 1c2) that is laid across the longitudinal centerline L and in the lower opening 1b. , Engaging claws 1d extending downward from an edge portion of the lower opening 1b along the longitudinal centerline L are provided. For example, the solid drug M is contained in the container 1 while being placed on the pedestal 1c. A portion of the container portion 1 above the opening 1a is closed to the outside. The area where the opening 1a is provided is a lower part of the container part 1, specifically, a region from the lower end of the container part 1 to 1/2 or less of the total height of the container part 1, preferably to 1/3 or less, and more preferably. Is an area of 1/4 or less.

As shown in FIG. 4, in this embodiment, the openings 1a are formed by dividing the lower container 1B at a plurality of locations along the longitudinal centerline L. The openings 1a are arranged on both sides of the lower part of the lower container 1B with the longitudinal centerline L interposed therebetween, and the arrangement modes of the openings 1a on both sides are mirror image symmetric with respect to the longitudinal centerline L. Further, as shown in FIG. 2, the center line L1 of the opening 1a in a cross section orthogonal to the longitudinal center line L (passes through the center of the opening 1a in the cross section and is orthogonal to the tangent line or the tangent plane of the outer surface of the lower container 1B). The line) inclines downward from the inside of the container 1 toward the outside.

The pedestal 1c is configured by alternately arranging two types of pedestal portions 1c1 and 1c2 having different forms along the longitudinal center line L at intervals. The pedestal portion 1c1 has a form in which two girders 1c1a are connected to the base portions 1c1b on both sides, and the inclined surfaces 1c1c are provided on the side portions of the base portions 1c1b on both sides. Each inclined surface 1c1c has an upward slope from the outside to the inside of the lower container 1B, and the lower end in the inclined direction is connected to the opening 1a. The width of each inclined surface 1c1c along the longitudinal centerline L is the same as or larger than the opening 1a. The pedestal portion 1c2 has a U shape as a whole.

The engaging claws 1d are respectively provided at a plurality of positions on both edges along the longitudinal centerline L of the lower opening 1b.

As shown in FIG. 5, the receiving portion 2 is formed in an elongated saucer shape along the longitudinal line L and has a shape that is recessed at a gentle slope from the outer peripheral portion toward the central portion, and the central portion has An elongated opening 2a is provided along the longitudinal centerline L.

As shown in FIGS. 2 and 3, the engaging claw 1d of the lower container 1B penetrates the opening 2a of the receiving portion 2 while elastically deforming, and then elastically restores to engage with the lower surface of the receiving portion 2. In this way, the receiving portion 2 is attached to the lower portion of the container portion 1 (lower container 1B). The receiving portion 2 attached to the lower portion of the container portion 1 extends obliquely upward from the lower portion of the container portion 1 with a gentle inclination so as to project outward with respect to the outer surface of the container portion 1 and is shown in FIG. Thus, the outer peripheral edge reaches a position higher than the upper edge of the opening 1a. Therefore, the opening 1a is in a state of being covered by the receiving portion 2 with the space S therebetween.

As shown in FIG. 1, the base of the hanger 3 penetrates through a slit-shaped insertion hole 1e provided in the container 1 (upper container 1A) so as to be vertically movable, and enters the inside of the container 1. I'm out. The base of the hanging device 3 is provided with an adjusting portion 3a having a large number of irregularities that can be engaged with the peripheral edge of the insertion hole 1e, and the tip of the hanging device 3 engages with the edge of the flush toilet. A hook portion 3b that can be stopped is provided. The base portion of the hanging tool 3 is inserted into the insertion hole 1e of the container portion 1, and the adjusting portion 3a is moved vertically in the insertion hole 1e to adjust the position of the container portion 1 with respect to the hook portion 3b. Then, when the container part 1 is put into the flush toilet and the hook part 3b of the hanging device 3 is locked to the edge of the flush toilet, the medicine supply tool (the container part 1 and the receiving part 2) is suspended by the hanging device 3. In this state, it is placed at a desired position in the flush toilet bowl.

Depending on the specifications of the flush toilet (the flush water flow method), specifically, the direct type {Fig. 7(a)}, the semi-tornado type {Fig. 7(b)}, the tornado type {Fig. 7(c)} described above. Although the jetting mode and the flow direction of the wash water are different depending on the difference of the above, the opening 1a of the container part 1 is provided in the lower part of the container part 1 above the opening 1a of the container part 1 in the medicine supply tool of this embodiment. Since the part is closed to the outside, it is difficult for the cleaning water to directly flow into the container portion 1 from the opening 1a during cleaning regardless of the specifications of the flush toilet. Therefore, in the direct-type or semi-tornado flush toilet, the wash water W ejected from each ejection port comes into contact with the upper portion of the container portion 1 and flows down along the outer surface of the container portion 1 to reach the opening 1a. By, for example, merging each other during the above, variations in the amount of the wash water W flowing into the inside of the container portion 1 from each opening 1a are alleviated. Then, the wash water W comes into contact with each part of the medicine relatively evenly, so that the variation in elution of the medicine is reduced and a certain usable period is secured. Further, in the tornado-type flush toilet, a large amount of flush water W that horizontally swirls along the inner surface of the toilet becomes difficult to directly contact with the medicine stored in the container portion 1, so that the medicine is consumed due to excessive elution. It is suppressed and a certain usable period is secured.

Moreover, in the medicine supply tool of this embodiment, since the receiving portion 2 is provided on the outer surface side of the container portion 1, as shown in FIG. 6, regardless of the specifications of the flush toilet bowl, the washing water W receives the washing water W. Is temporarily received in the space S between the receiving portion 2 and the outer surface of the container 1, and then flows into the container 1 from the space S through the opening 1a. At that time, the cleaning water W flows into the container portion 1 from the opening 1a so as to rise up the inclined surface 1c1c of the pedestal portion 1c1. Therefore, in the direct type or semi-tornado type flush toilet bowl, the variation in the amount of wash water W ejected from each ejection port is buffered by the pool of wash water W in the space S, and then the space S The wash water W once accumulated in the container 1 flows into the container 1 through the openings 1a of the container 1 in a uniform amount and uniformly contacts each part of the medicine contained in the container 1. In this way, the washing water W is evenly contacted with each part of the medicine, so that the variation in elution of the medicine is further reduced and a certain usable period is secured. Further, in a tornado-type flush toilet, since a large amount of flush water W that horizontally swirls along the inner surface of the toilet does not come into direct contact with the drug contained in the container portion 1, it is consumed due to excessive elution of the drug. Is further suppressed, and a certain usable period is secured.

The wash water W that has flowed into the container portion 1 through the opening 1a and has come into contact with the medicine flows out into the toilet through the lower end opening 1b of the container portion 1 and the opening 2a of the receiving portion 2 together with the elution component of the medicine.
