Further, the chemical liquid supply tool 1 is provided between the upper lid 3 and the lower container 2, and the spring member 8 for urging the upper lid 3 in the opening direction and the upper lid 3 opening with respect to the lower container 2 beyond a predetermined angle. And a stopper means 9 for restricting

As shown in FIGS. 12 to 17, the lower container 2 is made of a synthetic resin and has a deep bowl shape with an open top and a horizontally long elliptical shape in plan view. is there. This lower container 2
Is a shape in which an upper portion 2A located on the upper side and a lower portion 2B located on the lower side are integrally connected, and the upper portion 2A is formed so as to project more outward in the longitudinal direction than the lower portion 2B.

The bottom wall portion 10 of the lower container 2 is formed in a circular shape in plan view, and a drain port 11 is formed in the center thereof. Further, a plurality of (three in the illustrated example) plate-like long legs 12 projecting downward from the periphery of the drainage port 11 are provided on the lower surface of the bottom wall portion 10. The long leg 12 guides the chemical liquid led out from the drainage port 11 downward, and is inserted into the sink hole to mount the chemical liquid supply tool 1 on the water supply tray.

A plurality of small projections 14 (six in the illustrated example) protruding downward are provided on the outside of each long leg 12 on the lower surface of the bottom wall portion 10 (the lower portion of each water intake 13 described later). Each small protrusion 14 has a protruding length of about 1 mm, and each small protrusion 14 contacts the water supply tray when the chemical solution supplier 1 is installed on the water supply tray. Thereby, a space is secured between the water supply tray and the bottom wall portion 10,
A part of the water supplied from the water supply pipe to the water supply pan flows smoothly through the space into the drain hole. In addition, a space is secured between each water intake 13 and the water supply tray so that each water intake 13
The water is smoothly introduced into the lower container 2. In addition, although it is preferable that the plurality of small projections 14 are provided, it is not necessary to provide the small projections 14 on all the intake ports 13.

On the upper surface of the bottom wall portion 10, a plurality of (six in the illustrated example) water conduits 15 extending radially from the drainage port 11 are provided. In addition, on the lower surface of the bottom wall portion 10, a plurality (6 in the illustrated example) for introducing a part of the water supplied to the water supply tray into the lower container 2 at a position corresponding to each water conduit 15 individually. ) Is formed. A pair of support walls 16 extending along both side edges project from the upper surface of each water conduit 15, and the solid medicine is supported on each support wall 16. The water supplied to the water supply tray is mainly introduced into the lower container 2 from each water intake 13 and comes into contact with the bottom surface of the solid medicine when passing through each water conduit 15. At that time, the drug is eluted from the solid drug substantially uniformly, and the drug solution is discharged from the drain port 11.

An auxiliary drainage port 17 is formed at a portion located radially inward between the adjacent water conduits 15. Each auxiliary drainage port 17 plays a role of assisting the drainage of water by the drainage port 11.

Around the water conduit 15 is provided a ring-shaped peripheral wall 19 having an inner diameter slightly larger than the diameter of the contained solid medicine. A plurality of dehydration ports 18 (six in the illustrated example) are formed outside the peripheral wall 19 at positions corresponding to the respective auxiliary drainage ports 17. Further, slits 21 are formed in the upper end portion of the peripheral wall 19 at positions corresponding to the dehydration ports 18. When an excessive amount of water is introduced into the lower container 2 from each intake port 13, the excess water is drawn out from each dehydration port 18 via each slit 21, so that the water is not drawn into the peripheral wall 19. Excessive accumulation is prevented.

Since the upper portion 2A of the side wall portion 22 of the lower container 2 is formed longer than the lower portion 2B in the longitudinal direction, the upper portion 2A is projected to the outside in the longitudinal direction more than the lower portion 2B by that amount. It has a shape. At the boundary between the upper portion 2A and the lower portion 2B of the side wall portion 22, that is, the lower surface of the portion protruding outward in the longitudinal direction, a volatilization port 23 opening downward is formed. The volatilization port 23 plays a role of releasing the volatile fragrance from the solid medicine to the outside.

An impermeable wall 24 is integrally provided at a boundary between the upper portion 2A and the lower portion 2B of the side wall portion 22. The impermeable wall 24 extends upward so as not to block the volatilization port 23, and in the present embodiment,
Inclined inward in the longitudinal direction toward the top. The upper end of the water shield wall 24 is located at least above the volatilization port 23. As a result, since the volatilization port 23 faces vertically downward, when the water that has dropped from the water supply pipe to the upper lid 3 flows down along the upper surface of the upper lid 3 and reaches the volatilization port 23, the flowing water is the volatilization port. It is prevented from flowing into the lower container 2 from 23, and it falls on the water supply tray as it is. As a result, the solid chemicals contained in the lower container 2 can be removed from the water supply pipe through the upper lid 3
It is possible to prevent contact with water that has fallen to the. Moreover, even if a part of the water that has dropped directly from the water supply pipe to the water supply tray jumps up from the water supply tray and scatters toward the volatilization port 23, the scattered water enters the lower container 2 through the impermeable wall 24. Since it is prevented from doing so and falls along the impermeable wall 24 to the water supply tray, it is possible to prevent contact with the solid medicine. In this way, the volatilization port 23
By blocking the inflow of water from the
It is possible to dissolve an appropriate amount of solid drug.

In addition, the impermeable wall 24 does not necessarily need to be inclined inward in the longitudinal direction, and may stand upright in the vertical direction, or may be inclined outward in the longitudinal direction.

An engagement claw 50 is formed on the upper end of the side wall 22. The tip of the engaging claw 50 is bent outward in a hook shape.

In addition, the surrounding wall 28 is not continuous with the engaging claws 50, and a space exists between both ends of the surrounding wall 28 and the engaging claws 50.

As shown in FIGS. 18 to 23, the upper lid 3 is formed in an elliptical shape in plan view in conformity with the shape of the lower container 2 in plan view, and is, for example, a dish-shaped one with a shallow bottom formed of synthetic resin. .. By closing the upper opening 20 of the lower container 2 with the upper lid 3, it is possible to prevent water from the water supply pipe from directly splashing on the solid medicine. The top lid 3 is not limited to synthetic resin, and can be made of pottery, glass, or the like. Further, the shape of the upper lid 3 is not particularly limited, either.
In addition to the dish shape described above, various shapes such as a bowl shape, a cap shape, and a flat plate shape can be adopted. One or a plurality (five in the illustrated example) of volatilization ports 30 are formed in the upper lid 3, and the volatile fragrance from the solid medicine is emitted from the volatilization ports 30.

A hinge mechanism 4 is integrally provided on the outer surface of the upper lid 3. In the present embodiment, the hinge mechanism 4 is provided at one position at the center of the upper lid 3 in the longitudinal direction. The hinge mechanism 4 includes a pair of left and right first base portions 40 that are integrally provided on the upper lid 3 with a space therebetween, a pair of left and right shaft portions 41 that are integrally provided with the first base portion 40, and an integral portion of the shaft portion 41. A pair of left and right second bases 4 provided in the
2 and a connecting portion 43 that connects the respective second base portions 42 and has a U-shape in a plan view. The thickness of the first base portion 40 and the second base portion 42 decreases toward the shaft portion 41, so that the thin shaft portion 41 is formed. In the hinge mechanism 4, the connecting portion 43 is inserted into the hinge insertion groove 26 of the lower container 2. The connecting portion 43 is integrally provided with a pair of left and right locking portions 44. Locking part 4
In No. 4, the tip is bent outward to form a hook. When the connecting portion 43 is inserted into the hinge insertion groove 26 of the lower container 2, the tips of the respective locking portions 44 enter the locking holes 27 from the hinge insertion groove 26 and reach the outer wall surface of the side wall portion 22 of the lower container 2. The hinge mechanism 4 is prevented from coming out of the hinge insertion groove 26 by being caught by the left and right step portions 2C (shown in FIGS. 3 and 13).

On the inner side surface of the upper lid 3, an inwardly extending engaging projection 51 is integrally provided at a position facing the hinge mechanism 4. The engaging projections 51 constitute the fixing means 5, and the upper cover 3 in the closed state is fixed to the lower container 2 by engaging the engaging claws 50 of the lower container 2 when the upper cover 3 is closed.

On the inner side surface of the upper lid 3, a mounting portion 31 for mounting a leaf spring 80 constituting the spring member 8 is integrally provided inside from a position facing the engaging protrusion 51. The mounting portion 31 is formed by connecting four plate-shaped members in a rectangular frame shape in accordance with the outer shape of the plate spring 80.
An insertion port 32 into which one end of the above can be inserted is opened at the end. The mounting portion 31 is provided on the inner side surface of the upper lid 3 so that the insertion port 32 faces downward in the vertical direction when the upper lid 3 is closed (see FIG. 7). Further, the attachment portion 31 is provided on the inner side surface of the upper lid 3 so as to be located inside (the solid medicine side) of the hinge attaching / detaching portion 25 of the lower container 2 when the upper lid 3 is closed (FIG. 7). See).

Between the pair of left and right first bases 40 of the upper lid 3, a rectangular parallelepiped second block body 91 that constitutes the stopper means 9 is integrally provided. The second block body 91 horizontally projects from the outer surface of the upper lid 3, and is arranged immediately above the first block body 90 of the lower container 2 when the upper lid 3 is closed. Then, the second block body 91 is the first block body 90 of the lower container 2 when the upper lid 3 is opened by being rotated by the hinge mechanism 4, that is, when the upper lid 3 opens the upper opening 20 of the lower container 2. The upper lid 3 is prevented from further opening by hitting against (see FIG. 11).
..

The maximum opening angle of the upper lid 3 is preferably as large as possible from the viewpoint that the solid medicine is easily accommodated in the lower container 2 from the upper opening 20. However, if the top cover 3 opens too much,
The hinge mechanism 4 is easily detached from the hinge attaching / detaching portion 25 of the lower container 2, the leaf spring 80 constituting the spring member 8 is easily detached from the attaching portion 31 of the upper lid 3, and the hinge mechanism 4 is opened after the upper lid 3 is opened.
There is a possibility that problems may occur such as the chemical liquid adhering to the inner surface of the upper lid 3 splashing as the upper lid 3 returns vigorously due to the elastic force of the above and the elastic force of the leaf spring 80. Therefore, the maximum angle at which the upper lid 3 opens is preferably 70 ° to 90 °, and is 90 ° in the present embodiment.

The maximum angle is a line (a short axis in the present embodiment) that passes through the center of the upper lid 3 in a plan view and is orthogonal to the rotation axis of the hinge mechanism 4 (a line that connects both shaft portions 41 in the present embodiment). It is defined as an angle formed by a line that passes through the center of the lower container 2 in a plan view and is orthogonal to a rotation axis of the hinge mechanism 4 (a line that connects both shaft portions 41 in this embodiment) (a long axis in this embodiment). .. Further, in the present embodiment, the first block body 90 and the second block body 9 that are in contact with each other when the upper lid 3 is closed.
The angle formed by the surfaces of 1 corresponds to the maximum angle (see FIG. 10).

The spring member 8 is constituted by a leaf spring 80 in this embodiment. The leaf spring 80 has a predetermined length, width and thickness, one end of which is inserted into the attachment portion 31 of the upper lid 3 and the other end of which is inserted into the hinge attachment / detachment portion 25 of the lower container 2. It is removably interposed between the upper lid 3 and the lower container 2.

When the upper lid 3 is open, the leaf spring 80 is bent in a substantially L shape so as to have at least one (one in the present embodiment) bent portion 81 (hereinafter, referred to as “first bent portion 81”). It is interposed between the upper lid 3 and the lower container 2 in a closed state (see FIG. 11). Then, in the state where the upper lid 3 is closed, the leaf spring 80 is folded back at the bent portion 7 (the upper end portion of the protrusion 29) to newly form a bent portion 82 (hereinafter, referred to as “second bent portion 82”). While being folded (see FIG. 7). In the closed state, the upper lid 3 is fixed to the lower container 2 by the fixing means 5 against the restoring force of the leaf spring 80, but when the pressing operation of the operating portion 6 releases the fixing by the fixing means 5. The restoring force of the leaf spring 80 urges the upper opening 20 in the opening direction. As a result, the upper lid 3 can be automatically opened with one push.

Further, when the upper lid 3 is closed, the leaf spring 80 is folded back by the bent portion 7 (the upper end portion of the protrusion 29), the second bent portion 82 projects upward, and the first bent portion 81 moves downward. The first bending portion 81 is held in the chemical liquid supply tool 1 in a state in which the first bending portion 81 is positioned below the bending portion 7 (see FIG. 7). When the first bent portion 81 is located below the bent portion 7, the first bent portion 81 is suppressed from projecting inside the lower container 2 when the upper lid 3 is closed, and the leaf spring 80 is formed. It can be folded compactly. This can prevent the leaf spring 80 from coming into contact with the solid drug contained in the lower container 2. Here, the leaf spring 80 folded back at the bent portion 7 is arranged along the inner wall surface of the lower container 2 so that the first bent portion 81 projects downward in the vertical direction as much as possible. Then, the leaf spring 80
Can be more compactly folded, and contact with the solid medicine in the lower container 2 can be prevented more effectively. For that purpose, it is preferable to provide a protrusion 29 on the upper end portion of the side wall portion 22 of the lower container 2 to raise the height position of the bent portion 7 to an appropriate height as in the present embodiment.

The material of the leaf spring 80 is not particularly limited, and a rubber material of natural rubber or synthetic rubber, a metal material such as stainless steel can be used. However, when the closed state of the upper lid 3 is maintained for a long period of time, the leaf spring 80 is held in the folded state during that time.
There is a risk of bending habit (elastic distortion). If the leaf spring 80 is bent, the biasing force (elastic force) of the leaf spring 80 is reduced when the upper lid 3 is opened, and as a result, the upper lid 3 may not be opened to a predetermined angle. Therefore, in order to suppress the bending habit of the leaf spring 80, it is preferable to use silicon rubber, which is hard to bend, as the material of the leaf spring 80.

Further, the bending habit of the leaf spring 80 is greatly affected by the hardness, thickness and width of the leaf spring 80. Therefore, among the silicone rubber, it is preferable to appropriately set the hardness, the thickness, and the width so that the bending habit of the leaf spring 80 can be effectively suppressed. For example, as the hardness of the silicone rubber, a Shore A hardness of 50 ° to 80 ° can be preferably exemplified. In the present embodiment, the hardness is 7 °.
It is 0 °. The Shore A hardness of silicon rubber can be measured by a hardness meter (durometer type A) according to JIS K6253. In addition, the thickness of the silicone rubber can be preferably exemplified by 1.0 mm to 2.0 mm, and is 1.5 mm in the present embodiment.
Is. Moreover, as the width of the silicone rubber, the larger the width, the more difficult it is to bend, and therefore it is preferable. The upper limit can be appropriately set according to the design of the chemical liquid supply tool 1, but 3 mm to 6 mm is preferable, and 4 to 5 mm is particularly preferable. It can be set to 5 mm in the present embodiment.

Further, in order to increase the opening angle of the upper lid 3, it is necessary to lengthen the length of the leaf spring 80. However, if the length of the leaf spring 80 is too long, the leaf spring 80 will not move when the upper lid 3 is closed. When folded, there is a possibility that the first bent portion 81 may largely project inward and come into contact with the solid medicine in the lower container 2. Therefore, the length of the leaf spring 80 is preferably 20 mm to 30 mm, and is 26 mm in this embodiment.

The leaf spring 80 can be formed by, for example, extrusion molding or press molding, but is preferably formed by press molding from the viewpoint of suppressing habit.

The solid medicine is a mixture of a surfactant having a cleaning effect and a volatile fragrance for emitting a scent. This solid drug, which is manufactured by tableting or kneading the above-mentioned raw materials, is excellent in cleaning effect and aromaticity, but is not limited thereto. For example, other components such as a deodorant may be mixed with the fragrance, or the deodorant may be mixed instead of the fragrance.

Considering that the elution of the drug from the solid drug is mainly performed from the bottom surface substantially uniformly, it is preferable that the solid drug has a constant horizontal cross section such as a columnar shape or a prismatic shape. As a result, bulkiness can be generated while maintaining the cross section (initial outer diameter), and the solid drug can be stably supported by the support portion 27 until the end of use. Incidentally, the solid drug may have other shapes such as a pyramid, a frustum shape, and a sphere, in addition to the above-mentioned one having a constant cross section, and in these cases, water is also the bottom surface of the solid drug. By contacting the solid medicine substantially uniformly, it is possible to dissolve the solid medicine while keeping the shape of the bottom surface substantially constant.

In the drug solution feeder 1 having the above configuration, first, the solid drug is placed on each support wall 27 of the lower container 2, and the upper opening 3 is closed by the upper lid 3 to store the solid drug in the drug solution supplier 1. Then, the chemical liquid supplier 1 is installed on the water supply tray of the water storage tank for flush toilet. When the shape of the water supply tray in plan view is a generally rectangular shape, the chemical solution supply tool 1 is installed so that the longitudinal direction thereof coincides with the longitudinal direction of the water supply tray.

The water supplied from the water supply pipe to the water supply tray partially flows into the water storage tank from the drain hole, while part of the water is introduced into the lower container 2 from each water intake 13 and passes through each water conduit 15. Contacting the bottom surface of the solid drug to dissolve the solid drug in an appropriate amount. The dissolved chemicals are mixed with water, led out from the drainage port 11 at the central position, and flow into the water storage tank through the flow hole. The liquid medicine stored in the water storage tank is discharged to the toilet bowl during flushing to wash the toilet bowl.

When all of the solid medicine in the inside is dissolved due to the use of the chemical liquid supply tool 1, the lower container 2 is held by one hand and the operating portion 6 is pressed with a finger, whereby the fixing means 5 is used. The fixation is released, and the upper lid 3 becomes rotatable with respect to the lower container 2. As a result, the upper lid 3 is automatically opened by the biasing force of the spring member 8 and the upper opening 20 of the lower container 2 is opened. With the other hand, a new solid drug is set in the lower container 2, By closing the upper lid 3, the attachment of the solid medicine is completed and the drug solution feeder 1 can be reused.
