Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a hanging container for a water storage tank, and more specifically, for example, it can be hung upside down in a water tank of a flush toilet, and is used for deodorization, disinfection, or pollution prevention. The present invention relates to a hanging container for a water storage tank that supplies a predetermined amount of the liquid contained in the tank to the water stored in the tank.

(Prior Art) Conventionally, a hanging container which is hung upside down inside the water tank of a flush toilet to supply a predetermined amount of liquid contents at a time has mainly comprised an inner plug attached to the mouth of the container body, a float tube which moves up and down depending on the water level in the water tank to close or open the inner plug's spout to collect a predetermined amount of liquid contents from the spout, and a cap screwed onto the neck of the container body to press the float tube against the inner plug's spout when the hanging container is not in use to prevent the liquid contents from spilling out.

(Problem that the invention seeks to solve) However, in conventional hanging containers of this type, when the float tube starts to lower, the liquid content flows out intermittently from the pouring port in pulsating manner, so the liquid flows out from the float tube, which is also the measuring cup. There was a problem in that it was not possible to accurately replenish a predetermined amount because the liquid content rippled and overflowed.

In addition, with conventional hanging containers of this type, the cap is removed immediately before the container is hung in the aquarium, so the liquid content may leak out from the float tube between the time the cap is removed and the container is hung in the aquarium. There was a problem of spillage and contamination of the surrounding area.

The purpose of the present invention was to solve these conventional problems, and the purpose of the present invention was to avoid causing pulsations in the outflow of the liquid from the spout of the middle stopper when the float tube is lowered, and without removing the cap. An object of the present invention is to provide a usable hanging container for a water storage tank.

(Means for Solving the Problems) The water storage hanging container of the present invention has a container body, a cylindrical base attached to the mouth of the container body at one end, and an inner tube at the other end. and an inner stopper having an outer cylinder; a spout defined by a truncated cone-shaped peripheral wall protruding toward the base side on a cover plate formed on the end surface of the inner cylinder of the inner stopper; The cylindrical body has an H-shaped cross section as a whole with a reservoir plate that partitions the inside at the middle part, and one end of the cylindrical body is loosely fitted into the gap formed between the inner cylinder and the outer cylinder of the inner stopper, and is buoyant. a movable float cylinder; a bulging portion formed approximately in the center of the reservoir plate and partially fitting into the spout with a small gap between the peripheral wall and the spout of the inner stopper; The cover forms a gap communicating with the small gap between the cover plate and the reservoir plate and comes into contact with the reservoir plate to prevent liquid from flowing out from the spout when the float tube rises due to buoyancy. A seal portion is formed to protrude around the entire outer circumference of the plate, and a seal portion is formed at one end of the outer cylinder of the inner stopper and the cylinder of the float cylinder, respectively, when the float cylinder descends due to a drop in the water level in the water tank. an engaging protrusion that engages with each other in the axial direction to stop and hold the float cylinder at a predetermined position; a cap that is screwed onto the neck of the container body and covers the inner stopper and the float cylinder; a pressing member formed on the top plate to extend inward in the axial direction and press the reservoir plate to the end face of the inner cylinder of the inner stopper by screwing and tightening the cap; and a pressing member formed on the top plate of the cap. and an external discharge port.

(Function) According to the water tank hanging container of the present invention, the cap of the container suspended in the water tank is rotated and loosened, and the pressing member of the cap is applied to the end surface of the cylinder inside the inner plug of the float cylinder storage plate. When the pressing force is released, when the water is at a predetermined level in the water storage tank, the reservoir plate is pressed against the end face of the inner cylinder of the inner stopper by the rising force of the buoyancy of the float cylinder, and the spout is maintained in a closed state. Therefore, once the water in the water storage tank is discharged, the float cylinder descends under its own weight, and the reservoir plate releases the closure of the spout on the end face of the inner cylinder of the inner stopper. When the float cylinder has descended a predetermined distance, its engaging protrusion engages with the engaging protrusion of the inner plug outer cylinder and stops, preventing further descent. This means that the distance between the spout and the reservoir plate during descent remains unchanged, so that a predetermined amount of liquid is always retained on the reservoir plate.

Next, as water is supplied to the water tank and the water level rises, the float tube rises due to buoyancy, and as the reservoir plate approaches the end surface of the inner cylinder of the inner stopper, it overflows the liquid held inside. The water is mixed into the water stored in the tank, and finally the spout is closed again by the reservoir plate. Such an operation of the float cylinder is repeated as the water level in the water tank rises and falls.

(Embodiments) Hereinafter, preferred embodiments of the hanging water storage container of the present invention will be described in more detail as shown in the accompanying drawings.

an outer cylinder 23 that forms an annular groove 24 in cooperation with the outer cylinder 23;
A plurality of engagement protrusions 2 are provided in the circumferential direction on the wall of the
3b. In addition, a plurality of discharge holes 23c for the liquid content are formed in the wall portion of the outer cylinder 23 near an axially intermediate portion between the annular protrusion 23a and the engagement protrusion 23b at equal intervals in the circumferential direction.

A cover plate 26 is integrally formed at the end of the inner cylinder 22 of the inner stopper 2 on the inner peripheral side. This cover plate 2
A spout 26a is formed in the center of the spout 6, and a peripheral wall 26b of the spout 26a has a truncated conical shape protruding toward the base 21 side. A seal portion 2 protruding in the direction of extension of the inner cylinder 22 is provided on the outer circumference of the cover plate 26.
6d is formed, and an air hole 26c is formed slightly toward the center of the seal portion 26d.

The float cylinder 3 is composed of a cylinder body 31 and a reservoir plate 32 formed to partition the inside at approximately the middle thereof, and is an integrally molded synthetic resin product having an H-shaped cross section as a whole.One end of the cylinder body 31 is loosely fitted into the annular groove 24 of the inner stopper 2. An engaging protrusion 31a is formed on the outer peripheral surface of the tip of this one end, and this engaging protrusion 31a and the engaging protrusion 23 of the inner plug outer cylinder 23
b, the movement of the float cylinder 3 in the direction of removal from the annular groove 24 is restricted. Near the engaging protrusion 31a at one end of the cylinder body of the float cylinder 3, a plurality of discharge ports 31b for discharging the content liquid are provided at equal intervals in the circumferential direction.

On the other hand, protrusions 31c and 31d are formed along the axial direction on the outer circumferential surface of the intermediate portion and the inner circumferential surface of the tip portion on the other end side of the reservoir plate of the cylinder 31, and the inner circumferential surface of the intermediate portion is provided with an annular shape in the circumferential direction. A protrusion 31e is formed.

The reservoir plate 32 in the float tube 3 includes a bulging portion 32a whose central portion bulges out in a truncated conical shape toward the spout 26a of the inner stopper 2, and the bulging portion 32a is
The reservoir plate 32 faces the cover plate 26 and the seal portion 26d
When pressed against the peripheral wall 26b, as shown in FIG.
It has a shape that corresponds to the spout 26a so that it opens a small gap 33 and fits partially, that is, halfway, into the spout 26a, and the seal portion 26d protrudes from the cover plate 26 as described above. 2
A gap 34 is also formed between the reservoir plate 32 and the reservoir plate 32 facing the same, and this gap 34 is connected to the spout 26a.
A small gap 33 between the peripheral wall 26b and the bulge 32a
It communicates with the inside of the container body 1 via.

The cap 4 has a female thread 41a formed on the inner circumferential surface of the peripheral wall 41 and is screwed into an external thread 11a formed on the outer peripheral surface of the neck 11 of the container body 1 so that it can be tightened and loosened. A top plate 42 is formed and configured to cover the inner plug 2 and the float cylinder 3. An inner cylinder 43 protrudes from the inner surface of the top plate 42, and when the cap 4 is screwed onto the neck of the container body 1, the inner cylinder 43 connects the reservoir plate 32 to the sealing part 2.
The length is such that it comes into pressure contact with 6d. Therefore, this inner cylinder 43 acts as a pressing member.
A portion of the top plate 42 at the center of the inner cylinder 43 has a hole 4
4, and a plurality of external discharge holes 42a are formed at equal intervals in the circumferential direction on the outer peripheral side of the inner cylinder 43 of the top plate 42. In addition, the cylinder body 31 of the float cylinder 3 protrudes longer in the axial direction than the outer cylinder 23 of the inner plug 2.

The water tank hanging container of this embodiment configured as described above has the following characteristics when it is not in use, as shown in FIG.
When the cap 4 is tightened to the neck 11 of the container body 1, the inner cylinder 43, which is a pressing member provided on the top plate 42 of the cap 4, presses the reservoir plate 32 of the float cylinder 3, and the inner cylinder 43 is installed on the cover plate 26 of the inner stopper 2. It is clamped and fixed to the sealed seal portion 26d. Therefore, leakage of the liquid content from inside the container body 1 is reliably prevented by the pressure contact of the seal portion 26d to the reservoir plate 32.

When using, keep cap 4 tightened.
The container is hung upside down in the water tank by suitable means, and then the cap 4 is loosened and moved axially outward. As a result, the pressure contact between the inner cylinder 43 of the cap 4 and the seal portion 26d of the reservoir plate 32 is released, and the float cylinder 3 becomes freely movable in the axial direction. When the water surface in the water storage tank is above a predetermined height, the float tube 3 is raised by the water acting on the reservoir plate 32 through the hole 44 of the cap 4 and the external discharge hole 42a, and is raised by the buoyancy. Since the reservoir plate 32 is in pressure contact with the sealing portion 26d of the inner stopper 2, the content liquid does not come out outside of this pressure contacting portion.

Next, when water in the water tank is used and the water level falls, the float tube 3 descends, and the engagement protrusion 31a formed on the outer peripheral surface of the tip of one end of the tube body 31 engages with the engagement protrusion 23b of the inner stopper 2. The float tube 3 descends a certain distance and stops until it reaches the center point, and as a result, the float tube 3 is suspended by the inner plug 2.
The state shown in FIG. 2 is reached. As a result, the float tube 3
The bulging portion 32a of the reservoir plate 32 in is connected to the spout 26.
The sealed portion 2 of the reservoir plate 32 is pulled out from a.
Since the pressure contact with 6d is also released, the content liquid flows out from the container body 1 onto the reservoir plate 32 via the spout 26a. At that time, the liquid inside the container body is poured into the spout 2.
Small gap 33 between the peripheral wall 26b of 6a and the bulge 32a
A gap 34 between the empty reservoir plate 32 and the cover plate 26
The small gap 33 between the spout peripheral wall 26b and the bulging portion 32a is conical, and the content liquid from the spout 26a flows into the float cylinder 3.
The small gap 33 flows outward obliquely onto the reservoir plate along the slope of the bulging portion 32a as it descends.
As the float tube 3 gradually expands and the spout is fully opened, there is no intermittent outflow of the liquid from the spout when the float cylinder 3 is lowered, so the liquid flows out very quickly and does not ripple all at once. Pulsating outflow can be avoided. In this way, when the content liquid that has quietly flowed out onto the reservoir plate 32 is ensured to flow out onto the reservoir plate 32 to the extent that it blocks the air hole 26c provided in the cover plate 26 of the inner stopper 2, the outflow is stopped. The content liquid is not discharged from the discharge port 31b and is discharged from the reservoir plate 32.
A predetermined amount will accumulate on top.

Next, when water is replenished into the water tank and the top surface begins to rise, the float tube 3 also begins to rise,
The reservoir plate 32 presses against the seal portion 26d and the spout 2
The content liquid from 6a is prevented from flowing onto the reservoir plate 32. At the same time, the reservoir plate 32 and the cover plate 26
As the distance between the inner plug 2 and the inner plug 2 becomes smaller, the content liquid stored on the reservoir plate 32 is discharged from the discharge port 31b to the outer circumferential side of the float cylinder 3, and passes through the discharge hole 23c of the outer cylinder 23 of the inner stopper 2 to the cap. 4 external discharge hole 42
It is discharged from a into the water in the water tank and diffused.
Thereafter, an operation is repeated in which the liquid content is stored on the reservoir plate 32 of the float cylinder 3 as the water level in the water tank falls, and the liquid content on the reservoir plate 32 is discharged while the water level is rising.

(Effects of the invention) As explained above, according to the hanging water storage container of the invention, the cap can be loosened and the container turned upside down.
When used suspended in a water storage tank, when the float cylinder rises and the pressure contact between the reservoir plate and the seal part prevents the liquid from flowing out from the spout, the liquid flows between the spout surrounding wall and the bulge. When the float tube is lowered, the flow is flowing out into the gap between the reservoir plate and the cover plate through the small gap in the conical shape, and the flow is starting to flow diagonally through the small conical gap. Since there is no intermittent outflow of the content liquid from the outlet, pulsating outflow can be avoided. As a result, the liquid content quietly flows out onto the reservoir plate of the descending float cylinder, so that the measurement of the liquid content by the reservoir plate is very accurate, and the quantitative nature of the supplied liquid content can be maintained.
Furthermore, according to the water tank hanging container of the present invention, it is not necessary to completely remove the cap when using the container, and it is only necessary to loosen the cap to allow movement of the float tube, so that the container can be installed in the water tank. Even if some liquid content spills from the float cylinder, it does not immediately contaminate the surrounding area, and ease of handling can be improved.
