[Detailed description of the device] This device is designed to be suspended upside down in a water tank of a flush toilet, for example, and the water level in the tank is lowered by flushing, and the water level is raised by replenishing water into the tank. , deodorant, fragrance,
The present invention relates to an improvement in a hanging container for a water storage tank for supplying a small amount of liquid inside the tank for disinfection or prevention of contamination.

The above-mentioned container is equipped with an inner stopper fitted into the mouth of the container body, and a float cylinder fitted into the inner stopper so as to be movable in the axial direction within a predetermined range, and the container can be turned upside down to create a water storage tank. When the float tube is suspended in the tank, the liquid content accumulates on the reservoir plate as the water level falls and the float tube descends, and as the water level rises and the float tube rises, the liquid content on the reservoir plate is discharged to the outside. The applicant of this invention previously proposed this (see Utility Application No. 55-19554 and Utility Application No. 55-261ω).

This invention further improves the cover plate of the inner plug and the reservoir plate of the float cylinder, which were previously proposed by the applicant mentioned above.
When a container is turned upside down to hang it in a water tank, a large amount of the liquid inside the container leaks out instantly or scatters outside the tank, resulting in waste and staining the area around the tank. The purpose of the present invention is to provide a hanging container for a water storage tank that can prevent this from occurring.

Side 2
2a protrudes somewhat in the axial direction.

Although not shown, it is preferable that the cover plate 26 be provided with holes for venting air.

The float cylinder 3 is made of a synthetic resin integrally molded product, and the base end of the cylinder 31 is fitted into the cylindrical groove 24 of the inner plug 2 so as to be movable in the axial direction. engaged protrusion 3
1a engages with the engagement protrusion 23b of the outer cylinder body 23, thereby restricting movement of the float cylinder 3 in the extraction direction.

The cylindrical body 31 is provided with a plurality of discharge ports 31b for discharging the liquid at equal intervals in the circumferential direction in contact with the distal end side of the engagement protrusion 31a. Projections 32c and 31d are formed radially on the surface,
An annular protrusion 31e is formed at the middle portion of the inner peripheral surface.

A reservoir plate 32 for the liquid content is integrally formed on the inner circumferential surface of the boundary between the proximal end and the intermediate portion of the cylinder 31 .

This reservoir plate 32 has an inclined part 32b that presses against the contact part 26d of the cover plate 26 on the inner circumferential side of an outer circumferential part 32a perpendicular to the axial direction, and is parallel to the outer circumferential part 32a on the center side of this inclined part 32b. An intermediate portion 32c is formed, and the intermediate portion 32c
A cylindrical protrusion 32d with a bottom is formed on the center side of the truncated conical valve body 32e. The valve body 32e is formed in a shape and size that comes into close contact with the conical valve seat surface 26b of the cover plate 26 from the inside, and the outer circumferential portion 32a has a distal end surface 22a of the inner cylinder body 22 of the inner stopper 2. A sealing annular projection 32f is formed which presses into contact with the sealing ring.

As shown in FIG. 3, guide protrusions 32g are formed on the outer peripheral surface of the protrusion 32d of the reservoir plate 32 to protrude radially.
These protrusions 32g are slidably fitted into the annular protrusion 26c at the inner peripheral end of the cover plate 26 without any gaps.

The cap 4 has a female thread 41a formed on the inner circumferential surface of the peripheral wall 41 and is removably fitted to a male thread lla provided on the outer circumferential surface of the opening 11 of the container body 1, and is integrated with the peripheral wall 41 into the top plate 42. is formed to cover the inner plug 2 and the float cylinder 3.

An inner cylinder 43 is formed on the inner surface of the top plate 42, and the inner cylinder 43 is disposed so as to be in pressure contact with the sealing annular projection 32f on the outer circumferential portion 32a of the reservoir plate 32.

Note that the cylinder body 31 of the float tube 3 protrudes longer in the axial direction than the outer cylinder body 23 of the inner plug 2.

In the water storage hanging container configured as described above, when the container is not in use, the cap 4 is attached to the container body 1, as shown in FIG.
The inner cylinder 43 provided on the top plate 42 of the cap 4 comes into pressure contact with the outer peripheral part 32a of the reservoir plate 32 of the float cylinder 3, and the sealing annular protrusion 32f of the reservoir plate 32 is pressed against the inner cylinder 43 provided on the top plate 42 of the cap 4. At the same time, the inclined part 32b of the reservoir plate 32 is pressed against the contact part 26d formed on the cover plate 26 of the inner plug 2, and the float cylinder 3 is connected to the cap 4 and the inner plug 2.
It is sandwiched between.

In this unused state, leakage of the liquid content from inside the container body 1 occurs between the sealing annular protrusion 32f and the distal end surface 22a of the inner cylinder body 22.
1 and the inclined portion 32b of the reservoir plate 32 and the contact portion 26d of the cover plate 26 are used as sealing portions to reliably prevent this.

The abutting portion 26d compresses the annular groove 26e and is elastically pressed against the inclined portion 32b to ensure sufficient sealing.

Further, the truncated conical valve body 32e is located away from and below the conical valve seat surface 26d.

In use, the cap 4 is removed from the mouth 11 of the container body 1, and then the container is inverted in a water storage tank such as a flush toilet, and suspended thereon by an appropriate means.

In this case, when the container is turned upside down, the float cylinder 3 descends due to gravity, and as shown by the solid line in FIG. There is almost no leakage from the outlet 26a to the reservoir plate 32 side.

Therefore, when the container is turned upside down, it is possible to prevent the content liquid from instantly flowing out in large quantities into the water storage tank or scattering outside the water storage tank.

In the operating state shown in FIG. 2, the cap 4 is removed and the float tube 3 is movable in the axial direction, so if the water level in the water tank is higher than a predetermined height, the float tube 3 It is raised by the water acting on the plate 32, and as shown by the gap line in FIG. Since the portion 32b is in pressure contact with the contact portion 26d provided on the cover plate 26 of the inner stopper 2, the content liquid does not come out outside of these pressure contact portions.

When the water level in the water tank is lowered by flushing, the float cylinder 3 is lowered, and the valve body 32e shown in solid line in FIG. 2 is closely supported by the valve seat surface 26b, and the content liquid However, during the descent, the valve body 32e does not come into close contact with the valve seat surface 26b, and the sealing annular projection 32f1 and the inclined portion 32b are separated from the distal end surface 22a1 of the inner cylinder body 22 and the contact portion 26d of the cover plate 26, respectively. Since the spout 26a is opened, the content liquid flows out from the inside of the container body 1 through the spout 26a onto the reservoir plate 32 and accumulates therein.

Next, when water is replenished into the water storage tank and the water level begins to rise, the float cylinder 3 also begins to rise accordingly.

In this case, since the lower end of the cylinder 31 of the float cylinder 3 has a large inner diameter, the volume inside the cylinder 31 becomes large, the buoyancy also increases, and the float cylinder 3 rises reliably.

As the float cylinder 3 rises, the inclined part 32b of the reservoir plate 32 fits into the spout 26a, and the distance between this and the circumferential surface becomes smaller, so that the liquid content on the reservoir plate 32 is transferred to the outlet 31b.
The discharge hole 2 of the outer cylindrical body 23 of the inner stopper 2
3c, it is discharged into the water in the water tank and diffused.

When the water level in the water tank rises to a predetermined height, the state returns to the state before operation, and the discharge of the liquid content from the discharge port 31b stops.

Thereafter, while the water level in the water tank is falling, the reservoir plate 32 of the float tube 3
The operation of storing the liquid on the top and draining the liquid on the reservoir plate 32 while the water surface is rising is repeated.

By repeating the rise and fall of the float tube 3, the inner plug 2
Small air bubbles are generated between the outer cylinder body 23 of the outer cylinder body 23 and the cylinder body 31 of the float cylinder 3, but since the small air bubbles are discharged from the discharge hole 23c provided in the outer cylinder body 23 to the outer peripheral surface, Float tube 3
There is no adverse effect on the lifting and lowering operations of the float cylinder 3, and the float cylinder 3 operates smoothly.

In addition, since the discharge hole 23c of the outer cylinder 23 of the inner stopper 2 is provided with a large distance downward from the discharge hole 31b of the cylinder body 31 of the float cylinder 3, the water in the water tank flows back toward the inside of the container body 1. can be prevented from happening.

In the above embodiment, the cap was removed, but this idea uses a cap with an external discharge hole on the top plate, and by loosening the cap and moving it in the axial direction, the float tube can be raised and lowered. You may also do so.

Further, in the sealing portion between the reservoir plate and the cover plate of this invention, the sealing annular protrusion may be provided on the inner stopper side such as the cover plate.

Furthermore, in this invention, when the content liquid runs out, the float cylinder 3 is pulled out from the inner stopper 2, a refill container equipped with a nozzle is used, and the nozzle is inserted into the spout 26a to fill the contents of the refill container. Pour the liquid into the container body 1 and close the inner stopper 2.
The container according to this invention can be used repeatedly by pushing the float tube 3 into the container.

As explained above, according to this invention, the float tube 3 is provided with a reservoir plate 32 facing the cover plate 26 of the inner stopper 2, and the protrusion 32d provided on the reservoir plate 32 is connected to the spout 26 of the cover plate 26.
6a and protrudes outward from the tip of the protrusion 32d to form a valve body 32e, and the valve seat surface 26b that comes into close contact with the valve body 32e is connected to the inner surface of the spout hole 26a on the outer circumference side of the cover plate 26. In this way, when the cap 4 is loosened or removed and the container is inverted, the valve body 32e comes into close contact with the valve seat surface 26b by gravity, so that when the container is attached to the water tank, it is sometimes necessary to invert the container. However, a large amount of the liquid inside the tank may instantly leak out into the tank or scatter outside the tank, resulting in wasted liquid or staining the surrounding area of the tank. The effect is that there is no

Furthermore, according to the water tank hanging container of the present invention, when the water level in the water tank is above a predetermined height and the float tube 3 is rising due to water acting on the reservoir plate 32, and when the water surface of the container body is When pressing the float tube against the inner stopper with a cap screwed onto the inner stopper, the sealing annular protrusion 3 of the reservoir plate 32
2f comes into pressure contact with the tip surface 22a of the inner cylinder body 22 of the inner stopper 2, and at the same time, the inclined part 32b of the reservoir plate comes into contact with the contact part 26d so as to elastically deform it. Even if there is some pressure, the inclined part and the abutting part are in tight pressure contact over the entire circumference, and together with the presence of the other seal parts, the content liquid spout can be completely closed when the float tube is raised. In addition, it is possible to completely prevent liquid leakage from within the container body through the spout when the cap is attached, especially before using the hanging container.
