Configured. The periphery of the cover tube portion 28 is configured as a cleaning liquid reservoir.
[0025]
The case of using the eyewash container configured as described above will be described. For example, the container is inverted from the state shown in FIG. 1 and the liquid is introduced into the measuring chamber R as shown in FIG. Then, as shown in FIG. 7B, a liquid that is higher than the height of the measuring cylinder 5 is returned into the container body A, and a predetermined amount of liquid is measured into the measuring chamber R. Next, as shown in FIG. 7C, when the eye 31 is positioned above the spout 18 of the eyewash cup C and the body 2 is squeezed, the liquid whose pressure has been pressurized is discharged from the lower end of the liquid passage 6 to the liquid flow path. The air in the upper part of the metering chamber R passes through the air flow path b, passes through the air flow path b, passes through the extraction tube 23 and is ejected in the form of a mist through the outlet 18 and can be washed. The eyewash is collected in a liquid reservoir around the cover cylinder 28 and discarded after the eyewash. If necessary, the eye wash cup C can be removed from the metering tap B to wash the eye. Further, if the rotating body is rotated to the position shown in FIG. 2, a coarse mist-like jet can be jetted, and if it is rotated to the position shown in FIG. 3, only liquid can be jetted, and if it is rotated to the position shown in FIG.
[0026]
8 to 10 show another embodiment of the present invention. In this embodiment, the air flow path b is opened around the liquid flow path a at the junction of the flow paths. An example is shown.
[0027]
In the present embodiment, the fixing part B 1 has a rod-like protrusion 12 standing at the center of the upper surface of the casing top wall 9, a support cylinder 13 standing around it, and a short outer support cylinder 32 standing around it. Also, a pair of first liquid grooves 14 are formed on both sides of the upper end of the rod-like protrusion 12 to form a liquid flow path, and an air flow path is formed at the outer peripheral upper end of the support cylinder 13. For this purpose, a pair of first air grooves 15 are provided. Further, a liquid through-hole 16 communicating with the liquid passage 6 is formed in the top wall 9 between the rod-shaped protrusion 12 and the support tube 13, and the top wall 9 between the support tube 13 and the outer support tube 32 is measured. An air through hole 17 communicating with the inside of the chamber R is formed.
[0028]
Further, the rotating part B 2 extends a flange-like top plate part 20 that extends slidably on the fixed part top wall 9 from the upper end edge of the peripheral wall part 19 that is rotatably fitted to the fixed part peripheral wall 8. The upright tube portion 21 is erected from the inner peripheral edge of the top plate portion 20. The standing cylinder portion 21 has an inner peripheral lower end fitted to the outer periphery of the outer support cylinder 32 so as to be airtight and slidable, and a reduced diameter inner peripheral surface of the intermediate part is airtightly and slidable to the outer periphery of the support cylinder 13. In addition, the upper end portion is raised above the support cylinder 13 and the jet port 18 is opened at the tip end portion. Further, a circumferential direction connecting a top surface of the seal tube portion 33 that is liquid-tightly and slidably fitted between the rod-shaped protrusion 12 and the support tube 13 and an inner surface of the intermediate portion of the upright tube portion 21. They are connected by a plurality of connecting plates 34 and are configured so as to rotate together.
[0029]
In addition, a pair of second liquid concave grooves 24 extending from the lower end to the lower position of the first liquid concave groove 14 are provided vertically on the inner periphery of the seal cylindrical portion 33, A second air groove 25 extending vertically from the lower end to the lower position of the first air groove 15 is provided in the sliding contact portion. Each of the first liquid grooves 14 has a circular arc shape in plan view, and each of the second liquid grooves 24 has a square shape in plan view, and each of the first air grooves 15 and each second groove. Each of the air concave grooves 25 has an arcuate belt shape having a wide plan view.

【The invention's effect】
As described above, the eye wash container of the present invention can always eject a substantially constant amount of liquid by a simple operation, and can mix the ejected liquid with air to be ejected in a mild mist with little irritation to the eyes. In addition, it exhibits various effects such as easy handling and ease of use.
[0033]
Further, in the container of the second aspect of the invention, it is possible to maintain a state in which leakage of the liquid can be prevented even if the liquid ejection path is closed and the container falls down, and a rough mist and fine mist can be obtained by a simple switching operation. The liquid can be ejected in a variety of shapes.
[0034]
Further, in the container according to the third aspect of the present invention, since a liquid-only ejection form is added, it is possible to eject liquid with further changes.
