JPS5833437Y2 - Chemical injection container for descaling circulating bath pots - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a drug injection container for removing scale such as grime adhering to the inside of a circulation type bathtub.

Embodiments of the present invention will be described below based on the drawings.

In the figure, reference numeral 1 denotes a container body made of elastic synthetic resin, and one end side of the container body 1 is a frusto-conical portion 1b having a pull-out prevention film strip 1a over the entire outer periphery. A spout 1d having a male screw 1C on the outer periphery is provided at the tip of the truncated conical portion 1b.

Further, at the other end of the container body 1, there is a cap screwing part 1f having a male screw 1e on the outer periphery, and a film strip 1 to prevent extraction over the entire outer periphery.
A hose connection port 1j is formed of a truncated cone-shaped portion 1h having a diameter of 3.g, and is provided with a check valve 11 inside.

A cap 2 is screwed into the cap screwing part 1f of the hose connection port 1j, and after storing the scale removing agent 3 in the container body 1, a cap 4 is screwed into the spout 1d.

Therefore, when removing scale adhering to the inside of the circulating bath pot, the spout 1d of the container body 1 with the cap 4 removed is inserted into the lower opening of one side wall of the bathtub communicating with the lower pipe of the bath pot. At the same time, insert the truncated conical part 1
Fit part b tightly.

Additionally, the cap 2 is removed from the cap threaded portion 1f of the hose connection port 1j in the container body 1, and one end of the hose is fitted into the hose connection port 1j, and the other end of the hose is fitted into a water faucet to supply water. .

By supplying water into the container body 1, the medicine 3 inside is dissolved by the tap water, and the dissolved liquid is poured into the lower opening of the bathtub,
It passes through the lower pipe of the bathtub, the circulation path inside the bathtub, and the upper pipe of the bathtub, and overflows from the upper opening of the bathtub.

When the solution begins to overflow from the upper opening of the bathtub, stop the water supply from the water faucet, and connect the hose connection port 1j.
Remove the hose from the machine and leave it for example overnight.

In this case, even if the hose is removed from the hose connection port 1j,
Since the check valve 11 in the hose connection port 1j is closed by the reverse pressure of the solution in the bathtub, the solution flows into the hose connection port 1.
It is not discharged from j to the outside.

By doing this, the scale adhering to the circulation path within the bathtub is liberated by the chemical action of the solution.

Next, by removing the truncated conical body 1b of the container body 1 from the lower opening of the bathtub, the scale in the circulation path in the bathtub is discharged from the lower opening of the bathtub along with the solution. The conical body 1b is tightly fitted into the upper opening of the bathtub, a hose is fitted into the hose connection port 1j, and water is supplied in the same manner as described above.

Tap water supplied from the upper opening of the bathtub via the container body 1 passes through the upper pipe of the bathtub, the circulation path inside the bathtub, and the lower pipe of the bathtub, and is discharged from the lower opening of the bathtub. The scale remaining in the circulation path inside the bathtub is thoroughly washed away.

As described above, the present invention provides a truncated conical structure having a film strip around the entire outer periphery to prevent the injection of scale removing chemicals from being removed from one end of the main body of the injection container that is attached to the circulation path in the circulating bath pot. Because it has a shaped body, even if the inner diameter of the lower opening of the bathtub that communicates with the lower pipe of the bathtub or the upper opening of the bathtub that communicates with the upper pipe of the bathtub differs depending on the bathtub manufacturer,
One end of the injection container body can be completely and tightly fitted into the lower or upper opening of the bathtub.

In addition, a hose connection port is provided at the other end of the injection container body, which is made up of a cap threaded portion having a male screw on the outer periphery and a truncated conical portion having a membrane strip to prevent extraction over the entire outer periphery. In the case of a relatively small hose, it is enough to fit it into the threaded part of the cap, and in the case of a relatively large diameter hose, it is enough to fit it into the truncated conical part, so any diameter hose can be used. The male screw or pull-out stopper film strip allows the hose to be tightly fitted, and the hose will not come off from the hose connection port due to water supply pressure.

Furthermore, since a check valve is provided in the hose connection port, even if the hose is removed from the hose connection port, the solution in the bathtub will not be discharged to the outside from the hose connection port.

Furthermore, by refilling the empty injection container with a descaling agent (sold separately), you can remove scale from the bathtub as many times as you like, or use only tap water using the empty injection container. The inside of the bathtub can be washed at any time, making it particularly suitable for descaling and cleaning household circulating bathtubs.
