Description

[Detailed description of the invention] [Industrial field of application] This invention is a pedal-type metered dispenser that allows a fixed amount of soap solution, disinfectant, etc. to be taken out from the container at any time, mainly used in hospitals. Regarding improvements.

[Conventional technology and its problems]

Generally, this type of metered-dose dispenser has a liquid storage chamber made of a cylinder or bellows above the mouth of a bottle containing a soap solution, etc., and a bottle cap connected to the suction pipe and a movable cap on the nozzle side. A check valve ball is interposed in each opening, and the volume of the liquid storage chamber can be compressed by pushing with an elbow or stepping on the foot, thereby making it possible to dispense a certain amount of soap solution.

The above-mentioned quantitative dispensers tend to be of the foot-operated type because it is necessary to wash both hands at the same time, but most of them are of the so-called air pump type that operates using compressible air pressure. However, there were variations in the amount of liquid discharged with a single foot operation, and the drive mechanism of the movable cap that compresses the liquid storage chamber was complicated, making maintenance of this part time-consuming. There were still some problems that needed to be improved as a seed metering dispenser.

[Means for solving problems]

Therefore, the present proposal uses a bellows containing a spring to watertightly connect a bottle cap that can be fixed to a holder and a movable cap equipped with a nozzle.
The above-mentioned problems have been solved by providing check valves at the openings of both caps, and by making it possible to press the movable caps with a mechanically actuated arm that is connected to the pedal via a connecting rod. It was resolved all at once.

[Effect]

The proposed dosing device has a movable cap that is pushed down via an arm that is actuated precisely by mechanical means, so that it is possible to reliably dispense a fixed amount or amount of liquid commensurate with the amount of pushdown. It is something that plays.

〔Example〕

Hereinafter, the configuration of the present invention will be described in more detail based on the embodiment shown in the drawings. 1 is a holder that can be fixed to a wall surface etc., 2 is a bottle cap that is fitted and fixed to the holder 1, and A liquid suction port 2'' is provided in the center of the recess 2', and a suction pipe 4 that reaches the bottom of the bottle 3 is connected to the lower surface of the liquid suction port 2''. Further, 5 is a movable cap with a nozzle 6 projecting on one side, 7 is a seat through which a liquid feed port 7' is provided on the lower surface of the cap 5, and 8 is a movable cap with its lower end connected to the bottle cap 2, and its upper end connected to the bottle cap 2. bellows 9 each watertightly connected to the movable cap 5;
is elastically loaded in the bellows and assists in its restoration; springs 10 and 10' normally close the liquid suction port 2'' of the bottle cap and the liquid supply port 7' of the catch seat 7 to act as a check valve; These are the bulbs that make up the valve.

Next, let's talk about the drive mechanism of the dispenser.
Reference numeral 11 denotes an arm supported vertically and movably on the back plate 1' of the holder, and its tip side is brought into contact with the upper surface of the movable cap 5.

Further, reference numeral 12 indicates a connecting rod such as a wire with an outer whose one end is connected to the base end of the arm 11 and the other end is connected to the pedal 13.
By stepping on the arm 11, the arm 11 can be mechanically moved up and down within a certain range.

In the figure, reference numeral 14 indicates a cover that is placed above the holder 1, reference numeral 15 indicates a guide provided on the outer periphery of the movable cap 5 on which a flange can be slidably contacted, and reference numeral 16 indicates an auxiliary spring that pushes up the arm 11. , these are all provided as necessary.

In addition to using the above-mentioned wire as the connecting rod in the drive mechanism, as shown in FIG. However, the same effect as the above example can be obtained.

The specific operation of the dispenser for soap liquid, etc. of the present invention will be described below. First, when the bellows 8 is filled with soap liquid etc. due to previous use, when the pedal 13 is depressed, the arm 11 is wire 12
At the same time, the bellows 8 is compressed by the lowered distance.
The soap solution, etc. inside the bellows is fed to the valve ball 1 of the liquid feed port 7'.
0' is pushed up and a fixed amount is immediately discharged and supplied through the nozzle 6.

After supplying the soap solution, the pedal 13
When the pressure is released, the bellows returns to its original position mainly due to the spring pressure inside the bellows. At that time, the liquid feeding port 7' is closed by the valve ball 10' and the inside of the bellows becomes a negative pressure state, the soap liquid passes through the suction pipe 4, pushes up the valve ball 10 of the liquid suction port 2'', and is sucked up into the bellows 8, maintaining the original full state.

[Effect of idea]

As mentioned above, the quantitative dispenser for soap solution, etc.
The movable cap 5 is driven mechanically by the wire 12, etc., instead of the conventional physical method using air pressure, so there is no waste in the driving force, and the bellows can be moved. Accurate compression, always constant amount or pedal 1
In addition to being able to reliably dispense the amount of liquid that corresponds to the amount of depression in Step 3, the drive mechanism is significantly simplified, making maintenance and repair of this part easy, compared to conventional quantitative dispensing of this type. It exhibits excellent effects that could not be expected from a container.
