  By the way, in the chemical | medical solution dispenser mentioned above, although the magnitude | size of the leak hole provided in a bottle container body shall be preset according to the kind of chemical | medical solution, it will always leak a uniform quantity of chemical | medical solutions, In order to stably leak out a sufficient amount of the chemical solution, it is inevitable that it takes time to select the size of the leak hole. In addition, since the liquid level of the chemical liquid gradually decreases as the liquid leaks, there is a concern that the amount of the chemical liquid supplied will vary between the start of the chemical liquid leak and the end of the leak in the leak hole of a fixed size. There is. For this reason, there has been a strong demand for the emergence of a new chemical solution dispenser capable of easily and stably supplying a desired amount of chemical solution.

  The subject of this invention is related with the chemical | medical solution dispenser for toilets which supplies various chemical | medical solutions in the tank with a hand-washing of a flush toilet, and proposes the new chemical | medical solution dispenser which can dispense a chemical | medical solution with a fixed quantity. By the way.

The present invention comprises a container body having a mouth portion connected to a space for filling a chemical solution, and a base having a mounting portion for detachably attaching the mouth portion and holding the container body in an inverted posture. A chemical solution dispenser for dispensing chemical solution from a provided extraction hole to a hand-washed tank of a flush toilet,
The chemical liquid dispenser includes a stopper having a closing portion that closes the outlet hole, and a water tray that holds the stopper connected and receives water released from a hand-washing currant,
The water tray has a tray part for temporarily storing the received water, and an opening for discharging the water stored through the dish part,
The base includes an elastic body that elastically suspends and supports the water tray,
The elastic body presses the blocking portion against the pouring hole when the water tray is raised, and allows the chemical solution to be poured by opening the pouring hole when the water tray is lowered. This is a chemical dispenser.

The elastic body is made of a synthetic resin including a pair of annular portions that engage with the base and the water tray, respectively, and an elastic portion that connects the annular portions to each other,
The elastic portion includes a plurality of frames including an oval portion along the circumferential surface of the annular portion and a vertical connecting portion that forms a pair connecting the oval portion and each annular portion. Things are desirable.

  Provided on the outer peripheral side of the bottom of the water receiving tray is a water absorbing body for infiltrating the chemical solution from the dispensing hole, and the water absorbing body is integrally connected to the water receiving tray and held by a plurality of claw portions provided at intervals. It is desirable to do.

  A base that holds the container body filled with the chemical solution in an inverted position is formed with a discharge hole for discharging the chemical solution, and a plug body having a closing portion for closing the discharge hole, and the plug body are connected and held. And a water receiving tray that receives the water discharged from the hand-washing currant, the water receiving tray temporarily storing the received water, and an opening for discharging the water stored through the tray. Since the base is provided with an elastic body that elastically suspends and supports the water tray, the amount of water stored in the water tray is less than a predetermined amount and the water tray is in a raised position. While the pouring hole is closed, when a predetermined amount or more of water is stored and the water tray is in the lowered position, the pouring hole opens so that the chemical solution can be poured out. Regardless of the level of the chemical solution, a certain amount of chemical solution can be surely dispensed each time. Can. In addition, the amount of the chemical solution to be dispensed can be adjusted not only by the elastic force of the elastic body, but also by several factors such as the amount of water stored in the water tray and the size of the opening for discharging the stored water. The desired amount may be adjusted by selecting only the part that is easy to change, and can be relatively easily performed.

  The elastic body is made of a synthetic resin including a pair of annular portions that engage with each of the base and the water tray, and an elastic portion that connects the annular portions to each other. When it is assumed that a plurality of frames comprising an oblong annular portion along the circumferential surface of the ring portion and a vertical connecting portion that forms a pair connecting the oblong ring portion and each annular portion are provided. Since the water tray can be stably suspended and supported by the same elastic force with the frame having the same shape, the pouring hole can be reliably opened and closed every time.

  Normally, the opening area of the pouring hole is relatively small, and the liquid medicine to be poured out stays in a relatively narrow range, so there is a concern that it may not come into sufficient contact with the liquid chemical depending on the flow of water. In the case where a water absorbing body that permeates the chemical solution from the dispensing hole is provided, and this water absorbing body is integrally connected to the water receiving tray and held by a plurality of claw portions provided at intervals, the water absorbing body is discharged from the hand-washing currant. Water can flow into the water absorber through the gap between the claws, and the chemical solution that has permeated the water absorber can surely flow into the tank.
