Description

[Detailed explanation of the idea] "Industrial application field" This case concerns spill containers used to store deodorant liquid, etc.

``Prior Art'' Various containers are known that are suspended in the tank of a flush toilet and discharge deodorizing liquid or the like when the water stored in the tank is drained. For example, Jikko 47-
No. 41174 has a cylinder body with openings at both upper and lower ends fitted into the neck of the container, and a metering cylinder with both upper and lower ends closed fitted into the cylinder so that it can move vertically and not fall out. An inflow hole and an outflow hole are formed in the upper and lower sides of the measuring cylinder, respectively, and a float is attached to the lower end of the measuring cylinder, so that when the water stored in the tank is drained, the measuring cylinder moves into the container body. and descends relative to the cylindrical body, the inflow hole is closed by the cylindrical body, the outflow hole is opened, and the deodorizing liquid, etc. inside the measuring cylinder is discharged, and when it is injected into the tank, the measuring cylinder is closed. It is raised relative to the container body and the cylinder, the outflow hole is closed by the cylinder, and the outflow hole is opened so that the deodorizing liquid or the like inside the container flows into the metering cylinder.

``Problems to be solved by the invention'' There is also a known outflow container of this type that allows deodorizing liquid, etc. to flow into the tank when the amount of water stored in the tank increases. The drawback was that the large amount of water stored inside the tank diluted the deodorizing liquid, reducing efficiency. For this reason, as in the above-mentioned conventional example, a deodorant or the like is introduced into a relatively small amount of residual water that has been reduced by drainage, and is discharged together with the remaining water. By doing this, it has become possible to mainly perform flushing with only water that does not contain deodorant, and use the water remaining in the toilet bowl after flushing as water in which a highly concentrated deodorant or the like is dissolved.

However, in the case of the conventional outflow container that discharges deodorant etc. when draining water, when filling the tank with water, there is a large time difference between when the inlet hole opens due to the float rising and until the outflow hole is blocked. Therefore, during this period, the deodorizing liquid and the like inside the container would pass through the measuring tube and flow directly into the water stored in the tank.

This proposal minimizes the amount of deodorizing liquid, etc. that flows into the tank when the tank is filled with water, and also designs a storage chamber as large as possible to store the deodorizing liquid, etc. in preparation for discharge. Moreover, the discharge port can be set large to ensure that the liquid in the liquid storage chamber can be discharged within a short time, and the structure is also simple.

``Means for Solving the Problems'' A container body 1 with an inverted neck and neck 2 and a small diameter cylinder 5 are fitted into the neck and a large diameter tube is inserted from the lower end of the cylinder through an outward flange 6. A diameter cylindrical portion 7 is provided vertically, and a valve seat forming protrusion 8 is provided around the inner surface of the intermediate portion of the small diameter cylindrical portion, and an appropriate number of first vertical grooves are formed in the small diameter cylindrical portion above the ridge. a first member 4 with 9 arranged vertically;
The first engaging cylinder 1
4 is vertically provided on the outer edge of the lower end of the cylinder.
3 and a second member 11 provided with a second vertical groove on the cylinder wall of the cylinder, and a second engagement with a third vertical groove fitted into the first engagement cylinder 14. A second engagement protrusion 17a that engages with the first engagement protrusion 13 is attached to the upper end of the cylinder 17, and the lower end of the second engagement cylinder is loosely inserted into the large diameter cylinder part 7 and removed. A third member 15 attached to the upper surface of the top wall 16 forming an outflow valve with the facing flange 6, and having a peripheral wall 18 hanging from the periphery of the top wall.
and the second member 11 with respect to the first member 4.
and the third member 15 with respect to the first and second members.
are provided so as to be movable up and down, respectively, so that when the third member 15 rises relative to the first member, the upper end of the second engagement cylinder 17 pushes up the valve plate 12 to open the inflow valve, and the top wall 16 moves toward the outward flange 6. A closable outflow valve was formed in contact with the lower surface.

"Function" As shown in Figure 1, water is stored in the water storage tank,
In a state where the water level 20 has risen, the top wall 16 and the peripheral wall 1
The third member 15 is pushed up as a float by the indoor air formed by 8, and the lower outflow valve is closed.
In addition, the third member pushes up the second member 11, so that the upper inflow valve is also in an open state. In this state, the measuring chamber formed by the top wall 16 of the third member and the small diameter cylindrical portion 5 of the first member is filled with the fluid within the container.

When the water level in the water storage tank rapidly falls due to drainage, as shown in Fig. 2, the outflow valve formed by the top wall 16 and the outward flange 6 opens as the member descends as shown in Fig. 3, and the fluid in the metering chamber 19 is discharged. Then, the valve plate 12 of the second member is seated on the valve seat forming protrusion 8, thereby closing the inflow valve, and the third member 15 is closed as shown in FIG.
is suspended by the second member 11.

When the water in the tank is finished draining and water starts to be poured into the tank, the third member 15 rises relative to the first and second members from the state shown in FIG. 3, and the top wall 16 rises as shown in FIG. When approaching the outward flange 6, the second engaging cylinder 17 of the second member is moved to the third position with the outflow valve half closed.
The inflow valve opens by pushing up the valve plate 12 of the member,
Subsequently, the outflow valve is closed as shown in FIG. 1, and liquid storage in the metering chamber 19 begins by replacing the air in the metering chamber with the liquid inside the container.

"Example" The container of the present invention is composed of a container body, a first member, a second member, and a third member. Since the container is used in an inverted state, for convenience of explanation, the container will be described in an inverted state.

The container body 1 has a body part 3 having a mouth and neck part 2 hanging from the periphery of the bottom wall to the lower end thereof, and in this state is fixed in, for example, a water storage tank of a flush toilet. The fixing method may be any suitable method.

The first member 4 has a large diameter cylindrical portion 7 hanging from the lower end of the small diameter cylindrical portion 5 fitted into the neck portion 2 of the container body via an outward flange 6,
A valve seat forming protrusion 8 is formed on the inner surface of the intermediate portion of the small diameter cylindrical portion 5.
are provided around the periphery, and an appropriate number of first longitudinal grooves 9 are provided in the small diameter cylindrical portion above the protrusion. In the illustrated example, a gap 10 is formed between the inner surface of the neck and the outer surface of the small-diameter cylinder by reducing the diameter of the inner periphery of the lower end of the neck of the container body. It is advantageous that a flow path can be formed between the gap and the first vertical groove.

The second member 11 is vertically movably fitted into the small-diameter cylindrical portion above the valve seat-forming ridge 8, and by seating the lower surface of the peripheral edge on the upper surface of the valve-seat-forming ridge 8, the second member 11 It has a valve plate 12 with a hole that can be closed, and a first engagement cylinder 14 having a first engagement protrusion 13 is vertically provided from the lower surface of the center of the valve plate to the outer edge of the lower end. . A second longitudinal groove is provided in the first engagement cylinder.

The valve plate 12 is attached with a peripheral wall 12a that stands up from the periphery, and the peripheral wall 12a is curved and deformed by the valve plate.
This is provided to prevent the lower surface of the peripheral edge of the valve plate from being unable to sit on the upper surface of the valve seat forming protrusion 8 in a watertight manner. The valve plate 12 and the valve seat forming protrusion 8 form an inflow valve.

The third member 15 has a second engaging cylinder 17 erected from the center of the upper surface of the top wall 16, and a peripheral wall 17 from the periphery of the top wall.
8 is vertically installed, the second engagement tube is fitted into the first engagement tube so as to be movable up and down, and the first engagement projection of the first engagement tube is attached to the upper edge of the second engagement tube. A second engaging protrusion 17a is provided to engage with the strip 13 and prevent it from falling. Further, the second engagement cylinder is provided with a third vertical groove. The outer diameter of the top wall 16 is larger than the inner diameter of the small diameter cylindrical part of the first member and smaller than the large diameter cylindrical part 7, and the upper part of the peripheral wall 18 is provided so as to be loosely inserted into the large diameter cylindrical part 7. put. The upper surface of the top wall periphery and the outward flange 6 of the first member form a lower outflow valve;
In the closed state of the valve, as shown in FIG.
The valve plate is provided so as to be in contact with the lower surface of the vertical groove 9 and to push the valve plate upward above the lower end of the vertically divided groove 9. Further, as shown in FIG. 3, the upper inflow valve formed by the valve plate and the valve seat forming protrusion is closed, and the first and second engaging protrusions 13,
With 17a engaged, the lower outflow valve is completely opened.

"Effect of the invention" As mentioned above, in this invention, the second and third members, which were conventionally formed integrally, are slidably fitted as separate members, so the valve seat forming protrusion 8 of the first member and the second and third members are slidably fitted together. Valve plate 1
2 compared to the opening size of the inflow valve formed by
The opening size of the outflow valve formed by the member top wall 16 and the outward flange 6 of the first member can be increased, and the liquid in the metering chamber 19 can be reliably discharged within a predetermined time. Even though the outflow valve opening size is increased, the inflow valve does not open immediately when the third member starts to rise, but the inflow valve opens slightly before the top wall 16 approaches the outward flange 6 and closes the outflow valve. 2
Since the upper end of the engagement cylinder 17 opens the inflow valve on the lower surface of the valve plate 12, the time for both of these valves to be open and for the liquid in the container to flow directly into the tank without being stored in the measuring chamber is reduced compared to conventional methods. It can be shortened to a large width, thereby increasing the efficiency of deodorizing liquid, etc., and the second and third longitudinal grooves are formed in the first and second engaging cylinders of the second and third members, respectively. Because of this, the measuring chamber 19 can be set large, and because the second and third members are separately molded and their first and second engaging cylinders 14 and 17 are slidably fitted, the member structure is simplified. can be converted into
