Description

[Detailed description of the invention] The present invention is a deodorizing liquid that is suspended in a water storage tank such as a toilet, and is provided so that when the water stored in the tank is drained, a substantially fixed amount of the liquid inside the container is discharged. Concerning spill containers such as

Various containers of this type have been known in the past, but the container in this case is designed to ensure that a substantially constant amount of deodorizing liquid, aromatic liquid, etc. is discharged when the water stored in the tank is discharged. Also, when the container is installed upside down in a water storage tank, it is provided to prevent the liquid inside the container from leaking.

Referring to the drawings below, reference numeral 1 denotes a container body installed in an inverted state in a water storage tank (not shown), and 2 denotes a mouth and neck part that hangs downward when the container body is inverted. For convenience of explanation, the container will be explained in an inverted state.

The peripheral wall 4 of the stopper external portion 3 is fitted into the mouth and neck portion. The external part of the stopper has a horizontal wall 5 that closes the mouth surface on the lower surface of the mouth and neck, and a peripheral wall 4 that stands up from the horizontal wall fits in the inner surface of the mouth and neck in a watertight manner. A cylindrical portion 7 having a diameter is vertically disposed. The external shape of the stopper can be formed by a combination of two members, as shown in each figure.

A valve device 8 is provided in the upper part of the cylindrical portion 7 .
In this valve device, a valve hole 9 is bored in the center of the horizontal wall 5, and a valve body engaging protrusion 10 is attached to the inner surface of the middle part of the cylindrical part 7, so that the inside of the cylindrical part above the protrusion is closed to the valve hole 9. It has a chamber 11, and a valve body 12 is provided inside the valve chamber. The valve body has buoyancy, and when water in the tank enters the cylindrical portion, it rises and closes the valve hole 9, and when water is discharged from the cylindrical portion, it descends due to its own weight to form the valve body engaging protrusion. 10.
At the time of engagement, a gap is formed between the side surface of the valve body and the inner surface of the cylindrical portion, and the valve hole and the lower chamber 13 of the valve chamber are communicated through the gap. Valve body 12
As shown in Figures 1 and 2, it has an inverted bowl shape with a peripheral wall hanging from the top periphery, as shown in Figure 4 it has a ball shape, and as shown in Figure 5 it has an upper outer periphery. Various shapes such as a tapered inverted bowl shape may be considered.

A liquid discharge cylinder 14 is provided at the lower part of the cylinder part. The liquid discharge tube penetrates the bottom wall 6 at the lower end of the tube, has an upper end open in the middle of the lower valve chamber 13, and has a lower end opening below the lower surface of the bottom wall.

An outside air introduction hole 15 is provided in a portion of the bottom wall of the cylindrical portion. The inner opening 16 of the outside air introduction hole is located at the upper part of the lower chamber of the valve chamber, and communicates between the inside and outside of the cylindrical portion. It is preferable that the outside air introduction hole is also formed by providing an outside air introduction tube 15a.

In the above configuration, as shown in FIG. 1, when the water level 20 of the water stored in the tank is below, the valve body 1
2 is located at the bottom. In this state, the valve hole 9 remains open, but since the valve hole is a small hole and the liquid inside the container closes the valve hole, outside air does not enter the container, so the balance with the air pressure inside the container is maintained. This prevents liquid from dripping from the valve hole. When the water level 20 rises from the state shown in FIG. 1 as shown in FIG. 2, water also enters the cylindrical portion, causing the valve body 12 to rise due to buoyancy and close the valve hole 9. However, prior to the blockage, the air inside the cylinder enters the container through the valve hole 9 because water enters the cylinder and becomes pressurized as the water level rises. The air above the liquid surface on the other side will be pressurized.
Next, when the water level 20 falls as shown in FIG. 1 due to the use of the water in the tank, the outside air enters the cylinder from the outside air introduction hole 15, and the water in the cylinder is transferred to the liquid discharge tube 1.
4, and the valve body also descends due to the discharge.
Since the air above the container is highly pressurized, the air pressurizes the liquid surface, causing the liquid inside the container to be discharged from the valve hole 9. Due to the decrease in liquid due to this discharge, the air above the container When the air pressure becomes approximately equal to the outside pressure, liquid discharge from the valve hole will naturally stop.

The present invention has the above-mentioned configuration, and when the water stored in the tank increases, the valve is closed and the pressure inside the container increases, and when the water stored in the tank decreases, the valve opens.
Since the liquid inside the container is drained until the inside of the container becomes almost equal to the outside pressure, the liquid inside the container is naturally drained every time the tank is used for storage, which is convenient. teeth,
Since the volume of air inside the cylinder is fixed, the amount of liquid discharged from the container to relieve the high pressure inside the container is almost constant, so there is no need for too much or too little liquid such as medicine. Liquid can be used effectively. In addition, the lower end of the liquid discharge tube is lower than the lower end of the outside air introduction hole, and the upper end of the liquid discharge tube is located below the inner opening of the outside air introduction hole.
The replacement of outside air and water or liquid within the cylinder is quick and reliable. Furthermore, the upper end of the liquid discharge pipe is located in the middle part of the lower chamber of the valve chamber, and the inward opening of the outside air introduction hole 15 is also located at the upper part of the lower chamber of the valve chamber, so that the lower chamber part of the valve chamber is located below the upper end of the liquid discharge pipe. is a part that stores liquid, so when the container is turned upside down to install it in a water storage tank, some of the liquid inside the container will spill out from the valve hole 9, but the spilled liquid will flow into the valve chamber. The liquid will be stored in the part of the lower chamber where the liquid is stored, and will not spill outside the cylindrical part 7. Therefore, your hands will not get dirty, and the liquid will not spill when the container is turned upside down. It is also possible to prevent consumers from feeling uneasy about the structure of the container.
