Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a two-liquid mixing device that mixes two different types of liquids by sucking and ejecting them using a common liquid ejecting device.

There are various solutions that are usually stored individually in separate containers and mixed together before use. For example, liquids for removing dirt, rust, adhesives, etc. are one example. In such two-liquid mixing, it is desirable that liquid mixing be performed easily without spilling the liquid.

SUMMARY OF THE INVENTION An object of the present invention is to provide a two-liquid mixing device that uses a liquid ejecting device and is configured into a single integrated body that allows anyone to easily mix liquids without causing liquid spills.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is a first container body containing a first liquid;
2 is a second container body which accommodates a second liquid and is stored in the first container body 1; 3 is a common container body which holds the first and second containers 1 and 2 in a predetermined state; A common port member forms a liquid suction path, and 4 is a liquid ejection device.

The first and second container bodies 1 and 2 have threads 5 and 6 formed on the outer periphery of the mouth and neck, respectively, and the first container body 1 does not have any problems even when the second container body 2 is stored. Container body 2
It is set to a size that can accommodate approximately the same amount of the first liquid.

The common port member 3 is composed of a cap body 8, a common liquid path member 9, and a neck member 10.

The cap body 8 has a first peripheral wall 13 provided with a threaded groove 12 on the inner periphery which is threadedly engaged with the thread 5, and a threaded groove 14 which is threadedly engaged with the threaded thread 6 on the inner periphery of the cap body 8. a second peripheral wall 15, a first hanging short tube 17 that communicates with the upper end of the first suction pipe 16 that hangs down inside the first container body 1; The second suction pipe 18 that maintains the upper end of the second suction pipe 18 in communication with each other
A hanging short tube 19 and hanging rings 20 and 21 which are fitted into the necks of both container bodies 1 and 2, respectively, are provided vertically, and from the top surface of the top wall 11, the first and second hanging short tubes 1 are installed.
First and second upright short tubes 22 and 23 at positions corresponding to 7 and 19, and a large-diameter peripheral wall 25 having an engaging protrusion 24 on the outer periphery are respectively erected, and the top wall 11
, communication holes 2 for communicating the insides of the first and second suction pipes 16, 18 and both container bodies 1, 2 with the outside, respectively.
6, 27 and 28, 29 are provided.

The common liquid path member 9 extends upward from the lopsided top wall corresponding to the center of the top wall 11 of the cap-shaped body 30 that liquid-tightly surrounds the upper surface of the top wall 11 in the range including the upright short tubes 22 and 23. A small-diameter opening 31 that can be pulled out is provided upright.

The neck and neck member 10 has a stepped cylindrical shape with a large diameter at the bottom and a small diameter at the top, and an engaging protrusion 33 that engages with the protrusion 24 is provided around the inner periphery of the large diameter cylindrical portion 32. Also, a holding member 35 is provided on the inner periphery of the lower part of the small-diameter cylindrical portion 34 and is fitted into the small-diameter opening 31 to press it down. When installed, the stepped portion presses and fixes the top surface of the common liquid path member 9.

That is, the different types of liquids in both the containers 1 and 2 that have been sucked up by the first and second suction pipes 16 and 18 join together in the common liquid path member 9 and are mixed.

Next is the liquid ejection device 4, which is a well-known device, so to briefly explain it, it is a cap-shaped mounting member that has a finger hook 36 on one side and is attached to the upper opening of the mouth and neck member 9. 37, a cylinder 38 which is disposed inside the mounting member 37 and hangs down inside the mouth and neck member 9, and whose small diameter cylindrical portion at the lower end is fitted into and communicates with the small diameter opening 31, and the mounting member 3.
A vertically movable stem 40 having a bent nozzle 39 at the upper end and a cylindrical piston sliding in the cylinder 38 at the lower end passes through the cylinder 7 , and one end is connected to the mounting member 37 by a pivot 41 . The stem 4 is supported and the intermediate portion is engaged with the upper end portion of the stem 40.
The cylinder 38 has a suction valve at the lower end opening, and a spring inside the cylinder 38 that constantly pushes the stem 40 upward via a piston. , and a stem 40 above the cylindrical piston.
The lower end is equipped with a spherical discharge valve that can be raised and lowered at appropriate intervals.

Next, the operation of the above configuration will be explained. As mentioned above, when the different types of liquids in the first and second container bodies 1 and 2 are sucked up by the suction pipes 16 and 18, they are combined and mixed in the common liquid path member 9, so that under normal conditions, The cylinder 38 is substantially filled with the mixed liquid sucked up through the suction valve. In this state, for example, hook the thumb on the finger hook 36, hook the remaining fingers on the operating lever 42, pull the operating lever 42 in the direction of arrow A, and push the stem 40 downward. Then, since the upper end opening of the cylindrical piston is sealed with a discharge valve, the hydraulic pressure inside the cylinder 38 increases due to the downward movement, and when this hydraulic pressure reaches a specified value, the discharge valve is pushed upward, The mixed liquid in the cylinder 38 is injected outward from the nozzle 39 through the gap between the discharge valve and the stem 40. When the depressing operation is stopped when the mixed liquid in the cylinder 38 is almost injected, the nozzle 39, the operating lever 42, the stem 40, and the piston return upward due to the spring. becomes a negative pressure, the different liquids in both container bodies 1 and 2 are sucked up through suction pipes 16 and 18, respectively, merge and mix in the common liquid path member 9, and pass through the suction valve to the cylinder 38. One cycle of two-liquid mixing and injection operation is completed.

That is, according to the present invention, the required amount of two liquids can be mixed and taken out from the nozzle 39 by repeating the trigger operation of pulling the operating lever 42 in the direction of the arrow A.

In the above-mentioned present invention, the liquid ejection device 4 is skillfully used, and the first and second container bodies 1,
Since the different types of liquids in 2 are simultaneously sucked and ejected, the required amount of mixed liquid can be taken out when necessary without spilling by simply repeatedly operating the operating lever 42. Also, the first and second
The size of the container bodies 1 and 2 is changed, and the second container body 2 is
Since the container is stored in the first container body 1, the entire container is small and has a simple external shape, making it easy to handle. Furthermore, by appropriately determining the sizes of the communication holes 26 and 27, the mixing ratio of the two liquids can be adjusted. In addition, since the device is an integrated hand type, it can be held with one hand and directly injected into the required area, making it convenient to use.
