DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a first embodiment shown in FIGS. 1 and 2 will be described. Reference numeral 1 denotes a pressurized tube portion, which can be extended and contracted to both left and right ends of an intermediate tube portion 2. Further, elastic bellows-like cylindrical portions 3 and 3 whose outer end surfaces are closed by end plates are provided so as to communicate with each other. In addition, the upper wall of the intermediate cylinder portion is opened, the support cylinder 4 is erected from the peripheral edge of the opening, and the liquid storage cylinder 6 is erected from the upper end of the support cylinder via a tapered wall 5 upward and outward. An outward flange is attached to the upper end. A venting recess 7 described later is provided on the upper end surface of the liquid storage cylinder.

The upper end surface of the support cylinder is provided with an appropriate number of water holes 8.
. The bottom plate has a larger outer diameter than the support cylinder 4 as shown in the figure, and the outer peripheral portion thereof has a tapered wall 5.
It is preferable that the leg cylinder 10 which is placed on the upper surface of the inner peripheral portion and which is suspended from the lower surface of the bottom plate is fitted to the inner surface of the support cylinder 4 in a watertight manner.

In the first embodiment, the first member 11 having the above-described pressurized cylinder portion 1, the support cylinder 4, the tapered wall 5, the liquid storage cylinder 6, and the bottom plate with the leg cylinder are formed. The two members 12 are formed, and each member is integrally formed of a synthetic resin material. The first member can be formed by blow molding.

FIG. 3 shows a second embodiment. This embodiment is different from the first embodiment in that the lower half and the upper half of the first member 11 are separate members, the lower member is a first member 13, and the upper half and the bottom plate are integrated into a second member. The first member is formed by a male screw cylinder 21 as a support cylinder erecting from the intermediate cylinder part 2 of the pressure cylinder part 1, and the second member is screwed from the outer periphery of the bottom plate 9 to the male screw. The vertically provided cylindrical portion is used as the male screw cylinder 22 and is fitted to the inner surface of the male screw cylinder to suspend the inner cylinder 23 from the bottom plate.

FIGS. 4 and 5 show a third embodiment. In this embodiment, an outside air suction hole 25 is formed in a part of the lower part of the support cylinder 4 of the first member 11 in the first embodiment to form a first member 15, and other structures are the same as those of the first embodiment. It is formed in the same manner as the member 11.

The second member 16 has the outer peripheral portion of the bottom plate 9 closing the upper end surface of the support cylinder 4 placed on the upper surface of the inner peripheral portion of the tapered wall 5,
In addition, a leg tube 10 hanging from the outer peripheral portion of the bottom plate is fitted to the upper inner surface of the support tube 4 in a watertight manner. The lower end of the leg cylinder is the outside air intake hole
Position above 25. A valve hole 26 is formed in the center of the bottom plate 9 and the shaft 28 of the valve body 27 is fitted into the valve hole so that it cannot be pulled out. The valve body has a shaft 28 hanging down from the center of the elastic valve plate 29, and the lower surface of the outer peripheral portion of the elastic valve plate is pressed against the outer peripheral portion of the upper surface of the valve hole 26. The check valve 30 is formed with the lower surface. Between the outer surface of the shaft 28 and the inner periphery of the valve hole 26, for example, the planar shape of the valve hole is a triangle, and the cross-sectional shape of the upper part of the shaft is a columnar shape having the same diameter as the inscribed circle of the triangle, Corners of the triangular holes are provided to form water passages. The lower end of the shaft 28 has a larger diameter than the upper portion of the shaft to prevent the shaft 28 from being pulled out above the valve hole.

FIG. 6 shows a fourth embodiment. This embodiment has a first member 18 substantially similar to the first member 13 of the FIG. 3 embodiment.
In the center of the end plate of the bellows cylindrical portion 3, outside air suction holes 25, 25 are formed. Other structures are the same as those of the first member of the embodiment shown in FIG.

The second member 19 is almost the same as the embodiment shown in FIG.
Instead of the water holes 8 in the bottom plate 9 in the third embodiment of FIG. 3, a valve hole 26 is formed at the center of the bottom plate as in the fourth embodiment in FIG. In the valve hole, a valve element 27 provided in the same manner as in the embodiment of FIG.
Of the valve hole 26 and the lower surface of the outer peripheral portion of the elastic valve plate 29 pressed against the outer peripheral portion of the upper surface of the valve hole to form a check valve 30.

In the above embodiments, the same reference numerals are given to the same structural parts, and the description is omitted. In each of the above embodiments, in the case of the first embodiment shown in FIGS. 1 and 2 and the second embodiment shown in FIG. 3, the pressurizing cylinder passes through the inside of the liquid container 6 and the water passage hole 8. When an appropriate amount of washing water is put into the portion 1, the outward flange at the upper end of the liquid storage cylinder is applied to the face around the eye, and the elastic bellows cylinders 3 and 3 are elastically squeezed. As a result, the washing water in the pressurized cylindrical portion is ejected upward through the water passage hole 8 as shown in FIG. 2, and the eyes can be washed with the ejected water. At the time of the above-mentioned liquid ejection, if the upper end face of the liquid storage cylinder 6 is brought into close contact with the face,
The pressure in the cylinder is increased, and the pressure in the liquid storage cylinder 6 is reduced by the elastic restoration of the pressurized cylinder 1 by releasing the compression of the bellows cylinder. The problem can be solved by separating from the face or providing the ventilation recess 7 on the upper end surface of the liquid storage cylinder.

In the case of the third embodiment shown in FIGS. 4 and 5, and the fourth embodiment shown in FIG. 6, an appropriate amount of washing water is put in the liquid container 6, and the first and second embodiments are performed. As in the case of the embodiment, when the upper end surface of the liquid storage cylinder is brought into contact with the face around the eyes and the bellows-shaped cylinders 3 and 3 are squeezed with the outside air suction hole 25 closed with a finger or the like, the inside of the pressure cylinder 1 is compressed. The air opens the check valve 30 and raises the washing water, so that the eyes can be washed with the rising washing water. The air released above the water surface passes through the ventilation recess 7 or the gap between the face and is released into the outside air. The compression cylinder 1 is elastically restored.

[0016]

According to the present invention, the pressurizing cylinder 1 is formed by attaching elastic bellows-like cylinders 3 and 3 to both ends of the intermediate cylinder 2 at the left and right sides thereof. In addition, the pressurization and negative pressure of the pressurized tube can be performed by pressing and accelerating the elasticity of the bellows-shaped tube, and these can be operated with one hand, so that the operation is easy. Further, the liquid storage cylinder 6 having an outer diameter larger than that of the support cylinder is erected from the upper end of the support cylinder 4 erected from the intermediate cylinder portion, and the upper end surface of the support cylinder is closed by the bottom plate 9 with the water hole 8. It is easy to wash the eyes by applying the upper end to the facial part around the eyes and squeezing the washing water from the water passage hole 8 by pressing the bellows-shaped cylindrical portions 3 and 3 into the liquid storage tube 6. Since it can be returned, the washing water does not scatter.

Also in the case of the invention described in claim 2, the pressurizing cylinder 1
Is formed by attaching elastic bellows cylinder parts 3 and 3 to both left and right ends of the intermediate cylinder part 2, so that it has the same effect as in the case of the pressurized cylinder part according to claim 1. The liquid storage cylinder 6 having a larger outer diameter than the support cylinder is erected from the upper end of the support cylinder 4 which rises from above, the upper end of the support cylinder 4 is closed by the bottom plate 9 having the valve hole 26, and the elastic valve plate 29 is inserted into the valve hole. An elastic valve plate in which a shaft 28 hanging down from the center is fitted, and the valve hole 26 is pressed against the outer periphery of the upper surface of the valve hole.
Since the check valve 30 is formed by the outer circumference of the liquid container 29, the upper end surface of the liquid storage cylinder 6 is brought into contact with the face portion of the outer periphery of the eye, and the bellows-shaped cylindrical parts 3, 3 are squeezed to discharge air in the pressurized cylindrical part into the liquid storage cylinder. Then, it is easy to cause the liquid in the cylinder to rise upward by the release and to wash the eye with the rising washing water. Since the bellows-like cylindrical portions 3 and 3 are immediately elastically restored by opening the outside air suction hole 25, it is possible to continuously repress the pressurizing cylindrical portion having the bellows-like cylindrical portion.

According to the third aspect of the present invention, by providing the ventilation recess 7 in a part of the upper end surface of the liquid storage cylinder 6, the air in the liquid storage cylinder passes through the recess 7 during the eye washing as described above. Since the outside air flows into the liquid storage cylinder as well, the trouble of separating the upper end face of the liquid storage cylinder from the face or pressing the same as in the case where the concave portion 7 is not provided can be eliminated. I can do it.
