Description

[Detailed explanation of the invention] This invention, for example, removes the cap and hangs it upside down in a water storage tank of a flush toilet, and lowers the water level in the water tank by flushing, and replenishes the water level in the water tank. The present invention relates to an improvement of a hanging container for a water storage tank for supplying a predetermined amount of liquid for deodorization, disinfection, or stain prevention into the water storage tank due to an increase in the amount of water.

Conventionally, the above-mentioned water tank hanging container is known,
In conventional systems, it is difficult to reliably supply a predetermined amount of liquid content each time the water level in the water tank rises or falls, resulting in uneven supply.

It is difficult to distribute and supply the liquid content uniformly to the water in the water tank.
There were problems such as the possibility of unstable operation.

This invention solves the above-mentioned problem and can reliably supply a predetermined amount of liquid into the tank each time the water level rises or falls, and distributes this liquid evenly to the water in the tank. The object of the present invention is to provide a hanging container for a water storage tank that is easy to diffuse and can be expected to operate stably.

An embodiment of this invention will be described below with reference to the drawings.

In the drawings, 1 is a container body made of a synthetic resin hollow molded product, 2 is an inner stopper, 3 is a float tube, and 4 is a cap.

The container body 1 has a neck 11 having a thread 11a formed on its outer circumferential surface, and an opening 12 having a smaller diameter than the neck 11. On the outer circumferential side of the open end of the opening 12, a neck 11 having a diameter smaller than the neck is integrally formed. A flange 12a is formed.

The inner plug 2 is made of a synthetic resin integrally molded product, and has a cylindrical base 2.
1 is press-fitted into the mouth 12 of the container body 1, and the inner and outer cylinders 22.2 protrude in the axial direction from the mouth 12 integrally with the base 21.
3 is provided between these through a cylindrical groove 24, and the base 2
1 and the outer cylinder 23 is supported by the flange 12 a of the mouth 12 .

On the inner circumferential surface of the outer cylinder 23 of the inner plug 2, a guiding annular protrusion 23 a is formed at the tip, and an engaging protrusion 23 b is formed in the part located inside the cylindrical groove 24 . In the middle part, eight discharge holes 23C for the liquid content are provided at equal intervals in the circumferential direction.

A cover plate 26 is integrally formed on the inner peripheral side of the inner cylinder 22 of the inner stopper 2, and a spout 26a is provided at the center of the cover plate 26, and a peripheral wall 26b of the spout 26a is located on the base 21 side. It stands out.

The cover plate 26 has a conical shape with the outer circumferential side protruding in the axial direction away from the container body 1, and the outer circumference of the cover plate 26 has a seal portion 26 d that protrudes in the extension direction of the inner cylinder 22.
is formed, and an air hole 26C is formed slightly toward the center of the seal portion 26d.

The float cylinder 3 is made of an integrally molded synthetic resin product, and the cylinder body 31
The proximal end portion of the inner stopper 2 is fitted into the cylindrical groove 24 of the inner stopper 2 so as to be movable in the axial direction, and the engaging protrusion 31 is formed on the outer peripheral surface of the cylindrical body 31.
a engages with an engaging protrusion 23b of the outer cylinder 23, thereby restricting movement of the float cylinder 3 in the extraction direction.

Eight liquid discharge ports 31b are provided at equal intervals in the circumferential direction in contact with the distal end side of the engagement protrusion 31a of the cylindrical body 31. Guide protrusions 31C are formed to protrude radially, and these protrusions 3
1 C and the guide annular protrusion 23 a of the outer cylinder 23 with a small gap therebetween, and a reinforcing annular protrusion 31 d is provided on the inner circumferential surface of the intermediate portion of the cylinder 31 .

31e is formed.

A content liquid reservoir plate 3 is integrally provided on the inner peripheral side of the intermediate portion of the cylinder 31.
2 is formed in the center of the reservoir plate 32, and a protrusion 32a that fits into the spout 26a with a small gap is formed in the center of the reservoir plate 32. It is configured in a conical shape that protrudes away from the container body 1,
Further, a sealing portion 26d of the inner stopper 2 is provided on the outer periphery of the cover plate 26.
A flat seal portion 32b is formed opposite to the flat seal portion 32b.

The cap 4 is made of a synthetic resin molded product, and an internal thread 41a formed on the peripheral wall 41 is connected to an external thread 11 of the container body 1.
A top plate 42 is formed integrally with the peripheral wall 41 and is configured to cover the inner plug 2 and the float cylinder 3.

Note that the cylinder body 31 of the float cylinder 3 is smaller than the outer cylinder 23 of the inner plug 2.
The tip protrudes long in the axial direction.

In the suspended water storage container configured as described above, when the container is not in use, the inner surface of the top plate 42 of the cap 4 screwed into the container body 1 becomes the cylindrical body of the float tube 3, as shown in FIG. 31 and presses the float tube 3 against the container body 1 side, and the seal portion 26 is formed on the outer periphery of the cover plate 26 and the reservoir plate 32.
d and 32b are brought into pressure contact.

Therefore, leakage of the liquid content from inside the container body 1 is prevented due to pressure contact between the seal portions 26 d and 32 b and between the cylinder body 31 and the top plate 42.
This is reliably prevented by pressure contact with the

In use, the cap 4 is removed from the container body 1, and as shown in FIG. 2, it is hung upside down in a water storage tank such as a flush toilet by an appropriate means.

If the water surface in the water tank is higher than the specified height, the float tube 3
is rising, and the buoyancy exerted by this causes the seal portion 32b of the float tube 3 to come into pressure contact with the seal portion 26d of the inner stopper 2, so that the liquid content does not come out to the outside of the pressure contact portion.

The water in the water tank is used by flushing, and when the water level falls, the float cylinder 3 descends, and the engaging protrusion 31 a of the cylinder body 31 engages with the engaging protrusion 23 b of the inner stopper 2, and the float cylinder 3 stops descending, and is in the state shown in FIG. 2 where it is suspended by the inner stopper 2.

In this state, the protrusion 32 a of the reservoir plate 32 of the float tube 3
is extracted from the spout 26a of the cover plate 26 of the inner stopper 2, and flows from the container body 1 through the spout 26a to the reservoir plate 32.
The liquid content flows out onto the top.

In this case, the discharge port 31 b provided in the cylinder body 31 of the float cylinder 3
Since the lower edge of the inner stopper 2 is located above the lower end of the air hole 26C by an appropriate height, the liquid inside the air hole 26C is
If C is closed, the outflow of the liquid from the spout 26a is stopped, and the liquid will accumulate on the reservoir plate 32 without being discharged from the outlet 31b.

In this case, the discharge port 31b and the discharge hole 23C provided in the outer cylinder 23 are aligned or close to each other in the axial direction.

Next, when water is replenished into the water storage tank and the water level begins to rise, the float tube 3 also begins to rise, and its reservoir plate 32
Since the protrusion 32 a fits into the spout 26 a, the distance between the reservoir plate 32 and the cover plate 26 becomes smaller.
The liquid content on the reservoir plate 32 is discharged to the outside from the discharge port 31b, and most of it is pushed out radially from the discharge hole 23C of the outer cylinder 23 into the water storage tank on the outer circumferential side and diffused, and a part of the liquid is discharged from the discharge port 31b. It passes through the gap between the body 31 and the outer cylinder 23 and is diffused into the water in the water tank from its lower end.

When the water level in the water tank rises to a predetermined height, the float tube 3
floats up, the seal parts 32b and 26d come into pressure contact and return to the state before operation, and the discharge port 31b for the liquid content returns to the state before operation.
Emissions from will stop.

Thereafter, the operation of storing the liquid content on the reservoir plate 32 of the float tube 3 as the water level in the water tank falls and discharging the liquid content on the reservoir plate 32 from the discharge port 31b while the water level is rising is repeated.

In this case, since the guiding annular protrusion 23 a of the inner plug 2 and the guiding protrusion 31 C of the float cylinder 3 are opposed to each other with a small gap, when the float cylinder 3 moves up and down, the inclination Even though
By abutting the protrusion 31C on the protrusion 23a, the inclination angle of the float tube 23 is restricted to a very small amount, and its vertical movement is performed smoothly.

By the way, when the liquid content in the container according to the present invention runs out, it is sufficient to insert the nozzle of a refill container equipped with a nozzle into the spout 26a and inject the liquid content of the refill container into the container according to the present invention. This allows the container according to the present invention to be used repeatedly.

When the nozzle is inserted into the spout 26a, the spout 26a is sealed by the nozzle, but when the air hole 26C is provided in the cover plate 26 as in the above embodiment, the air hole 26C Since the hole acts as an air discharge hole of the container body 1, refilling of the contents can be carried out quickly.

As explained above, according to this invention, when the cap 4 is removed and the container is inverted and suspended in a water storage tank, a predetermined amount of the liquid content is deposited on the reservoir plate 32 as the float tube 3 descends due to the lowering of the water surface. is stored, and the next rise in the water level causes the reservoir plate 32 to
Since most of the liquid contained above is discharged to the outside through the discharge port 31b and the discharge hole 23C of the outer cylinder 23,
Unlike conventional systems in which the liquid content is discharged to the outside when the water level falls, the amount of liquid discharged is uneven, and the liquid content can be reliably supplied into the water storage tank in predetermined amounts.

In addition, with the conventional system described above, if the water level in the water tank remains in a downward state and does not rise during a water outage, there is a risk that the supply of the liquid content cannot be stopped, but with this device, when the water level rises next time. Since the liquid content is stored on the reservoir plate 32 without being discharged to the outside, even if the water surface remains in a downward condition, the liquid content will not be wasted and stable operation can be expected. .

Furthermore, unlike when the entire liquid content to be discharged at one time is supplied into the water storage tank from the lower end between the cylinder body and the outer cylinder of the float cylinder, it is difficult to spread it uniformly into the water in the water storage tank. In this case, as the reservoir plate 32 rises, a discharge hole 23C provided in the outer cylinder 23 is aligned with or adjacent to the discharge port 31b in the axial direction.
Since most of the liquid content is supplied into the water storage tank through the process, the liquid content can be pushed out in the radial direction, and supply can be started at an early stage when the water surface is below the discharge hole 23C. , it is possible to obtain the effect that it is easy to uniformly diffuse into the water in the water tank.
