  Next, a method for performing eyewash using the eyewash device 1 according to the present embodiment will be described. There are two types of eyewashing methods: downward eyewashing and upward eyewashing. First, downward eyewashing will be described. In order to perform eyewashing, first, a predetermined amount of eyewash is poured into the reservoir 31, and then the outer corner side contact portion 21 of the contact edge 20 is on the outer corner side, and the upper side contact portion 22 is on the upper side. In this manner, the contact edge 20 is pressed around the eyes while the face is faced down while the eyewash 1 is supported by fingers. Since the eye washer 1 is formed of an elastic material, the eye wash 1 is adjusted to an optimal state in close contact with the peripheral shape of the user's eye by appropriately adjusting the pressing force that presses the contact edge 20 around the eye. can do.

  Next, with the eyes open, the pressing portions 11 and 12 of the knob portion 10 are pressed so as to be sandwiched between two fingers. By this pressing, the knob part 10 is deformed, and the eyewash in the storage part 31 is pushed out to the eyeball side, so that the eyewash comes into contact with the eyeball and foreign matters such as pollen and dust are washed away. Then, by releasing the pressing of the knob portion 10, the knob portion 10 returns to its original shape by an elastic restoring force. Eye washing is performed by repeatedly pressing and releasing the knob 10 as described above.

  Next, upward eyewash will be described. Similarly to the downward eyewash method described above, after pouring a predetermined amount of eyewash into the reservoir 31, the outer edge side contact portion 21 of the contact edge 20 is on the outer corner side, and the upper side contact portion 22 is on the upper eye side. In this way, while supporting the eyewash device 1 with fingers, the contact edge 20 is pressed around the eye with the face facing down. While maintaining this state, the eyelid is repeatedly opened and closed with the face facing up and the eyewash in contact with the eyeball. Thereby, dirt adhering to an eyeball, foreign materials, such as pollen and dust, can be washed away.

  Since the receiving part 30 of the eyewash device 1 according to the present embodiment is provided with the bulging part 40 formed by partially bending the side wall outward, the reinforcing effect by the side end wall 41 and the peripheral end wall 42 is provided. Accordingly, the deformation of the receiving portion 30 when the knob portion 10 is pressed can be suppressed, and the deformation of the knob portion 10 is hardly transmitted to the contact end portion 20. As a result, it is possible to prevent a gap from being generated between the periphery of the eye and the contact edge, and effectively prevent the eyewash from leaking out of the eyewash device 1 during downward cleaning or upward cleaning. Can do.

  Further, the bulging portion 40 includes a side end wall 41 extending in a direction crossing the pressing direction of the knob portion 10 as a result of being formed by partially bending the side wall of the receiving portion 30 outward. This side end wall 41 acts as a reinforcing wall that is long in the vertical direction, which is the longitudinal direction of the bulging portion 40. As a result, the bulging portion 40 is particularly difficult to bend and deform in the direction along the surface of the reinforcing wall. That is, the bulging part 40 suppresses the bending deformation in the direction crossing the pressing direction of the knob part 10 (the radial direction of the receiving part 30) without increasing the deformation resistance in the pressing direction of the knob part 10 so much. As a result, the deformation of the knob portion 10 due to the pressing becomes difficult to be transmitted from the receiving portion 30 to the contact edge portion 20, the deformation of the contact edge portion 20 is prevented, and the eyewash liquid leaks from the eyewash device 1 during eyewash. It can be effectively prevented.

  Moreover, in the eyewash device 1 according to the present embodiment, the bulging portion 40 formed by partially bending the side wall of the receiving portion 30 in the vicinity of the abutment side contact portion 21 of the contact edge portion 20 outward. Therefore, when the knob portion 10 is pressed, deformation of the outer corner side of the receiving portion 30 having a large deformation amount can be effectively prevented. As a result, it is possible to effectively prevent liquid leakage from the vicinity of the corner portion 21 of the contact edge 20.

  Moreover, in the eyewash device 1 according to the present embodiment, since the wall-like member 50 extending downward from the storage portion 31 and the bulging portion 40 is provided, the receiving portion 30 is shaped like a wall via the bulging portion 40. It is fixed to the member 50. Thereby, the deformation | transformation of the receiving part 30 accompanying the press of the knob part 10 can be prevented more effectively, and the leakage of the eyewash liquid from the eyewash device 1 can be prevented. Furthermore, since the wall-like member 50 is also connected to the knob portion 10, the receiving portion 30 is fixed to the knob portion 10 via the bulging portion 40 and the wall-like member 50. Thereby, it becomes possible to prevent the deformation | transformation of the receiving part 30 accompanying the press of the knob part 10 still more effectively, and the leakage of the eyewash liquid from the eyewash device 1 can be prevented.

  In addition, as described above, by providing the bulging portion 40 formed by partially bending the side wall of the receiving portion 30 outward, deformation of the receiving portion 30 when the knob portion 10 is pressed is suppressed. Therefore, it is possible to use, as the elastic material used for molding the eyewash device 1, a material that is easy to deform and rich in flexibility as compared with a conventionally used material. Thereby, the user of the eyewasher 1 can press the knob part 10 with a light force, can suppress the hand shake of the eyewasher 1 when the knob part 10 is pressed, and the eyewash caused by the camera shake. Liquid leakage can also be prevented. Furthermore, when a person with weak finger strength, such as an elderly person or a child, uses it, it is possible to avoid a situation in which the finger gets tired in the pressing operation of the knob portion 10.

  As mentioned above, although one Embodiment of this invention was described, the specific aspect of this invention is not limited to the said embodiment. For example, as shown in the front view of FIG. 9, it is possible to employ a configuration in which the wall-like member 50 is omitted. Even with such a configuration, the deformation of the receiving portion 30 can be suppressed by the action of the bulging portion 40, so that the eyewash liquid is prevented from leaking from the eyewash device 1 when the knob portion 10 is pressed. be able to. Further, it is possible to employ a configuration in which the fin-like member 13 extending downward from the knob portion 10 is omitted, and a configuration in which the wall-like member 50 and the fin-like member 13 are omitted may be employed.

  Moreover, the wall-shaped member 50 can also be comprised so that it may extend below only from the storage part 31, as shown to the front view of FIG. Even if it is such a structure, while being able to ensure the self-supporting of the eyewash device 1, a deformation | transformation of the receiving part 30 at the time of pressing the knob part 10 can be prevented.

  Further, in the present embodiment, a configuration in which the single bulging portion 40 is provided in the receiving portion 30 in the vicinity of the outer corner side contact portion 21 of the contact edge portion 20 is employed. For example, the plurality of bulging portions 40 may be provided at predetermined intervals in the circumferential direction of the receiving portion 30.

  In the present embodiment, the receiving portion 30 is formed to extend from the knob portion 10 to the contact edge portion 20 in a stepwise manner as shown in the cross-sectional view of FIG. As shown in the cross-sectional view of FIG. 11, a configuration may be adopted in which the diameter is continuously extended from the knob portion 10 to the contact edge portion 20.

Further, in the present embodiment, as shown in the front view of FIG. 1, the outer corner side contact portion 21 of the contact edge portion 20 is configured to be higher than the upper side contact portion 22. For example, as shown in the front view of FIG. 12, the shape of the contact edge 20 is formed to be bilaterally symmetric, You may comprise so that the height of the eye side contact part 22 may become the same. With such a configuration, the user can use the eyewash device 1 without worrying about the orientation thereof.
