After pressing it around the eyewash, the eyewash is stirred with almost the same strength as the stirring water flow obtained by blinking in water just by pinching the knob part with your finger in a downward posture, This eliminates the need for blinking in water, which improves convenience during use. Eyewashing is possible even in an upward posture.

In addition, if a gap is formed between the portion of the liquid receiving portion where the eyewash solution enters and the portion connected to the eyepiece portion, the squeeze of the knob portion with the liquid filled between the eyes when the eyewash is performed in a downward posture. As a result, the liquid easily overflows from the eyepiece, but since the air gap is a space for the liquid to escape, the liquid does not easily overflow from the eyepiece. In addition, the gap portion reduces the feeling of pressure on the eye during eye washing. Furthermore, since the pinch force is not easily transmitted from the liquid receiving part to the eyepiece part, and the eyepiece part is difficult to deform, liquid overflow from the eyepiece part is less likely to occur.

  Furthermore, since the entire eye wash is a flexible material (e.g., elastomer) that can be elastically deformed, it has a soft feel, a good fit of the eye wash, and a squeeze of the knob with a soft elasticity. .

  Furthermore, if the eyewash is formed in a concave shape with the eyepiece, the liquid receiver, the knob, etc., the internal cleaning after use tends to be insufficient and dirt tends to accumulate.

According to the sixth aspect , when the ocular portion is formed in an elliptical shape and the flat portion of the knob portion is formed flat in the major axis direction of the eyepiece portion, when the knob portion is squeezed, the major axis direction is flattened. Since the part is pinched with the fingertip and squeezed in the short axis direction, the ocular ocular part is not easily deformed, and liquid leakage from the ocular part is less likely to occur.

According to the seventh aspect, when an adapter for holding the eyewash with the knob portion facing downward in a substantially horizontal state is provided as a separate member from the eyewash, when the eyewash is poured into the eyewash during use, It is no longer necessary to hold the bowl with one hand, and the eyewash solution can be injected by holding the eyewash bottle with either hand.

According to the eyewasher as the second means of the present invention, since the eyewasher is integrally formed of an elastically deformable flexible material, the eyewash is injected into the liquid receiving part at the time of eyewashing, and the eyepiece is placed in the eye. After pressing on the periphery of the eyewash, the eyewash is stirred with almost the same strength as the stirring water flow obtained by blinking in the water just by pinching the knob part with your finger through the adapter in a downward posture. Therefore, it is not necessary to blink in water that requires skill, and convenience during use is improved. Eyewashing is possible even in an upward posture.
In addition, if a gap is formed between the portion of the liquid receiving portion where the eyewash solution enters and the portion connected to the eyepiece portion, the squeeze of the knob portion with the liquid filled between the eyes when the eyewash is performed in a downward posture. As a result, the liquid easily overflows from the eyepiece, but since the air gap is a space for the liquid to escape, the liquid does not easily overflow from the eyepiece. In addition, the gap portion reduces the feeling of pressure on the eye during eye washing. Furthermore, since the pinch force is not easily transmitted from the liquid receiving part to the eyepiece part, and the eyepiece part is difficult to deform, liquid overflow from the eyepiece part is less likely to occur.

  In addition, the entire eyewasher is a flexible material that can be elastically deformed (e.g., elastomer), so it feels soft, the eyewash has a good fit, and the knob is squeezed via an adapter with a soft elasticity. become able to.

  Furthermore, if the eyewash is formed in a concave shape with an eyepiece, a liquid receiver, a knob, an adapter, etc., internal cleaning after use tends to be insufficient, and dirt tends to accumulate. Since the entire eyewasher is a flexible material that can be elastically deformed, the eyewasher can be turned over to be completely cleaned up to the inside.

  In addition, an adapter for holding the eyewash with the knob portion facing downward in an almost horizontal state is provided integrally with the eyewash, so when injecting eyewash into the eyewash during use, It is no longer necessary to hold it with the hand, and the eyewash solution can be injected by holding the eyewash bottle with either hand.

According to the ninth aspect , since the adapter is provided with non-slip processing, the fingertip does not slip carelessly with the adapter, so that it is easy to squeeze, and even if the fingertip is not squeezed with force, it is smooth with light force. You will be able to squeeze. In addition, when the slip stopper of the adapter is formed of a flat portion, the structure is simple and the finger pad is in close contact with each other, making it difficult to slip.

According to the tenth aspect , since the adapter is provided with non-slip processing, the fingertip does not slip carelessly with the adapter, so that it is easy to squeeze, and even if the fingertip is not squeezed with force, it is smooth with light force. You will be able to squeeze. In addition, when the slip stopper of the adapter is formed of a concave portion or a convex portion, the structure is simple, and the finger pad is bitten and becomes difficult to slip.

According to the eleventh aspect , since the adapter is provided with a non-slip process, it is easy to squeeze because the fingertip does not slip carelessly with the adapter, and even if the fingertip is not squeezed with force, it is smooth with light force. You will be able to squeeze. Further, when the adapter slip stopper is formed of a flat part and a concave part or a convex part, the structure is simple, the finger pad is in close contact, and the finger pad is bitten, making it more difficult to slip.

According to the twelfth aspect , when the ocular portion is formed in an elliptical shape and the flat portion of the adapter is formed flat in the long axis direction of the eyepiece portion, when the knob portion is squeezed via the adapter, the long axis Since the flat portion of the direction is pinched with the fingertip and squeezed in the short axis direction, the ocular ocular portion is not easily deformed, and liquid leakage from the ocular portion is less likely to occur.

According to claim 16 , since the adapter is integrally formed at the tip of the knob portion, when the knob portion is pinched with a finger and squeezed, when the knob portion slides from the finger and tries to slide upward, The adapter can be caught under the finger to prevent it from slipping.

According to claim 17, when the depth of the knob part is set to 15 to 25 mm, the knob part can be pinched with a fingertip without excess or deficiency, and the knob force is hardly transmitted from the liquid receiving part to the eyepiece part. Since the eyepiece is less likely to deform, liquid overflow from the eyepiece is less likely to occur.

Note that the gap portion may not have a direct relationship with the anti-slip processing of the knob portion, for example, an eye wash portion including an eyepiece portion that presses the periphery against the eye and a liquid receiving portion that stores the eye wash solution. And an eyewash having a knob for pinching with a finger, wherein the eyewash is integrally formed of a flexible material that is elastically deformable, and a portion of the liquid receiver that contains the eyewash and an eyepiece It is good also as an eyewasher characterized by the space | gap part being formed between the parts connected to.

  According to the eighteenth aspect, if the elastically deformable flexible material of the eyewash is made heat resistant, even if it is sanitized by boiling or steam from the hygiene aspect, it will not be plastically deformed.

  According to the nineteenth aspect, an eyewash set in which an eyewasher and an eyewash-containing bottle are combined is convenient at the time of use and can be stored hygienically.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  Eyewashers 10A to 10F of the first to sixth embodiments are embodiments in which the knob portion 14 is subjected to anti-slip processing.

  1 to 4 show an eye wash 10A according to the first embodiment, in which FIG. 1 (a) is a perspective view, (b) is a front view, FIG. 2 (a) is a side view, and (b) is a plan view. 3 (a) is a bottom view, (b) is a cross-sectional view taken along line AA in FIG. 2 (b), FIG. 4 (a) is a cross-sectional view taken along line BB in FIG. 2 (b), and (b) is used. It is a perspective view of a state.

  The eyewash device 10A includes an eyewash unit 13 including an ocular eyepiece unit 11 that presses the periphery of the eye and a cylindrical liquid receiving unit 12 that stores an eyewash solution, and a nipple-shaped knob for pinching with a finger. The eyewash device 10A is integrally formed of a flexible material that can be elastically deformed.

  As shown in FIG. 4 (b), the eye wash 10A sets the eye wash 10 to the state shown in FIG. 4 (a) at the time of eye washing, and the eye wash is made up to the level WL (see the alternate long and short dash line) of the liquid receiver 12. After injecting and pressing the eyepiece part 11 around the eye 9 (see the two-dot chain line), the knob part 13 is pinched with a finger (for example, thumb and index finger) 9a in a downward posture and squeezed several times. The eye 9 can be washed by the eyewash liquid being stirred in the liquid receiver 12 with almost the same strength as the stirring water flow obtained by blinking in water.

  The elastically deformable flexible material for forming the eyewash device 10A is not particularly limited as long as it is a material having elasticity and flexibility, but has moldability, chemical resistance, and heat resistance. Those without odor are preferred. Moreover, you may provide antibacterial activity as needed. Furthermore, in consideration of safety, those conforming to the Ministry of Health and Welfare Notification No. 20 and the 14th revised Japanese Pharmacopoeia General Test Method are preferable.

  Specific examples include thermoplastic resins, silicone resins, thermoplastic elastomers, natural rubber, urethane rubber, and the like, and these may be combined.

  In the case of a thermoplastic resin, for example, in the case of an olefin resin, it is known that moldability is improved by combining a thermoplastic elastomer or a hydrogenated styrene thermoplastic elastomer.

  As thermoplastic elastomers, moldability, chemical resistance, dirt resistance, environmental performance, cost, etc. are selected from styrene, olefin, urethane, polyester, polyamide, fluorine, and vinyl chloride. Among them, styrene type and olefin type are preferable. These may be used alone, or may be used by combining a plurality, for example, by laminating.

  Specifically, Tuftec (registered trademark) series H1052 and H1053 manufactured by Asahi Kasei Co., Ltd. Septon (registered trademark) series CJ001, CJ002, CJ101, CJ102 manufactured by Kuraray Co., Ltd. -1060N (styrene-based), Sirlink (registered trademark) series 3140, 3160, 4155, 4156 (olefin-based) manufactured by Toyobo Co., Ltd.

  The hardness is 50 to 80 as measured by JIS K6253 (durometer type A), and the tensile strength and elongation are 5 to 20 MPa and 300% tensile stress as measured by JIS K6253 (No. 3 dumbbell tensile speed 500 mm / min). The standard is a range of about 1.5 to 5 MPa.

  As shown in FIG. 1B, the standard dimensions of each part of the eyewasher 10A are as follows: the depth D1 of the eyewash part 13 is 18 mm, the depth D2 of the knob part 14 is 16 mm, and the front view width W1 of the liquid receiving part 12 28 mm, the front view width W2 of the base portion of the knob portion 14 is 16 mm, as shown in FIG. 2A, the side view width W3 of the liquid receiving portion 12 is 28 mm, the side view width W4 of the base portion of the knob portion 14 is 14 mm, As shown in FIG. 2B, the width W5 in the major axis direction of the eyepiece 11 is 42 mm, the width W6 in the minor axis direction of the eyepiece 11 is 32 mm, and the thickness of each part is about 0.8 to 2 mm. Whether the thickness is uniform or non-uniform can be selected as appropriate. When there is a desire to change the size of the eyewasher 10A, such as for larger or smaller sizes, the size may be enlarged or reduced proportionally. In the present embodiment, the depth D2 of the knob portion 14 is set to 16 mm. However, the range of 15 to 25 mm is preferable, and about 20 mm is optimal considering only the ease of knob. If it sets like the standard dimension of this embodiment, it can wash | clean efficiently even if the capacity | capacitance of eyewash is as small as 3-7 mL.

  Anti-slip processing is applied to the knob portion 14 of the eyewasher 10A. As the anti-slip process, when the eyewash part 11 is formed in an elliptical shape, a flat part 14 a that is flat in the major axis direction of the eyepiece part 11 is formed at a portion facing the knob part 14. Further, each flat portion 14a may be formed with, for example, a tear-like convex portion 14b. Note that the anti-slip processing is not limited to the flat portion 14a and the like, but may be embossing or the like.

  The liquid receiving part 12 of the eye wash part 13 is formed by a part 12A for receiving an eye wash and a part 12B connected to the eye part 11, and the long axis of the eye part 11 is provided between the parts 12A and 12B. On both sides in the direction, gaps 15 having inner surfaces that bulge outward from the inner surfaces of the eyepiece 11 and the liquid receiver 12 are formed.

  If the eyewasher 10A is configured as described above, the eyewasher 10A is integrally formed of a flexible material that can be elastically deformed. Therefore, during use, the eyewash is injected into the liquid receiver 12 to the level WL. As shown in FIG. 4 (b), after the eye wash part 11 is pressed around the eye 9, the knob part 13 is pinched with the finger 9a in a downward posture and squeezed several times to obtain a blink in water. The eyewash liquid is stirred in the liquid receiving part 12 with almost the same strength as the stirring water flow.

  In this way, it is possible to wash the eyes by simply pinching the knob portion 14 with a finger while keeping the posture downward, so that it is not necessary to blink in water that requires skill, and convenience in use is eliminated. To improve.

  In addition, since the knob portion 14 is provided with an anti-slip process (flat portion 14a and convex portion 14b), the fingertip does not slip carelessly by the knob portion 14, so that it is easy to squeeze and squeeze with force on the fingertip. Even without it, you can squeeze smoothly with light force.

  Since the anti-slip of the knob portion 14 is formed by the flat portion 14a, the structure is simple, and the finger pad is in close contact with the flat portion 14a, so that the flat portion 14a has a convex portion 14b. As a result, the finger pad bites in and becomes difficult to slip.

  Furthermore, since the entire eyewash device 10A is a flexible material (for example, elastomer) that can be elastically deformed, it has a soft feel, a good fit of the eyewash portion 13, and a squeeze of the knob portion 14 with a soft elasticity. It becomes like this.

  Furthermore, since the eyewash device 10A is formed in a concave step shape by the eyepiece part 11, the liquid receiving part 12, the knob part 14, and the like, internal cleaning after use tends to be insufficient, and dirt tends to accumulate. However, since the eyewasher 10A as a whole is a flexible material that can be elastically deformed, the eyewasher 10A can be turned inside out and completely cleaned, but the shape of the knob part 14 is from the bottom part of the knob part toward the base part when viewed from the front. If the shape is straight or flared, the eyewasher 10A can be easily turned over and completely cleaned up to the inside. Note that the elastically deformable flexible material of the eyewash device 10A is heat resistant, and therefore does not undergo plastic deformation even when sanitized by boiling or steam from the hygiene aspect.

  About the heat resistance of the said eyewash 10A (the following eyewash 10B-10J is the same), it confirmed that it did not plastically deform on the heating conditions described below.

[Boiling test]
i) An aluminum pan was filled with water enough to immerse the entire eyewasher 10A, covered and heated for 5 minutes.

  ii) The lid was opened and boiled for 3 minutes.

  iii) The eyewash 10A was taken out from the aluminum pan, cooled, and confirmed to be not plastically deformed.

[Boiling test with microwave oven]
i) 70 ml of water and eyewash 10A were placed in a boiling plastic bag.

  ii) Heated at 600 W for 3 minutes.

  iii) The eyewash 10A was taken out from the microwave oven, cooled, and confirmed that it was not plastically deformed.

  Regarding turning over the eyewash 10A (the following eyewashes 10B to 10I are the same), it is confirmed that it can be easily turned over when the measured value is in the range of 3 to 15N by the measurement method described below. did.

Measuring instrument: FUDO Rheometer Adapter: 3cmφ for crushing stress measurement
TSPEED: 6cm / min
Amplifier mode: F (normal operation)
Measurement room temperature: Room temperature As shown in FIG. 10, the eyewasher 10 </ b> A is placed on the rheometer pedestal 20 with the knob part 14 facing upward, and then the eyewasher 10 </ b> A is crushed from the knob part 14 with the adapter 21 according to the above conditions. The stress against crushing of the vessel 10A was measured. The measured value was the maximum value during crushing.

  In addition, when the eyepiece 11 is formed in an elliptical shape, the flat part 14a of the knob part 14 is formed flat in the major axis direction of the eyepiece part 11, so that when the knob part 14 is squeezed Since the flat part 14a in the long axis direction is pinched with the fingertips and squeezed in the short axis direction, the ocular eyepiece part 11 is not easily deformed, and liquid leakage from the eyepiece part 11 is less likely to occur. . In addition, since the eyepiece part 11 is formed in the left-right symmetric ellipse shape, there is no directionality when the eyepiece part 11 is pressed around the eye 9, and the eyepiece part 11 can be used conveniently. There is no problem even if it is formed.

  Further, when the side surface width W2 of the base portion of the knob portion 14 is 16 mm, the side view width W4 is 14 mm, and the depth D2 is set to about 16 mm, the knob portion 14 becomes thin and long. This makes it difficult for the pinch force to be transmitted from the liquid receiver 12 to the eyepiece 11, and the eyepiece 11 is less likely to be deformed, so that liquid overflow from the eyepiece 11 is less likely to occur.

  Furthermore, since the gap 15 is formed between the eyepiece 11 and the liquid receiving part 12 of the eyewashing part 13, when the eyes are washed in a downward posture, the liquid is filled between the eyes 9. When the knob part 14 is squeezed, the liquid easily overflows from the eyepiece part 11, but the void 15, which is an air reservoir, serves as an escape place for the liquid, so that the liquid does not easily overflow from the eyepiece part 11. In addition, the gap 15 reduces the feeling of pressure on the eye 9 during eye washing. Furthermore, since the pinch force is not easily transmitted from the liquid receiver 12 to the eyepiece 11 and the eyepiece 11 is not easily deformed, liquid overflow from the eyepiece 11 is less likely to occur.

  FIGS. 5A and 5B show an eye wash 10B according to the second embodiment, where FIG. 5A is a perspective view and FIG. 5B is a front view. The difference from the eyewash device 10A of the first embodiment is that the gap portion 15 is not formed between the portion 12A where the eyewash liquid of the liquid receiving portion 12 enters and the portion 12B connected to the eyepiece portion 11. The effects other than the gap 15 are the same as in the first embodiment.

  FIGS. 6A and 6B show an eyewash device 10C according to the third embodiment, in which FIG. 6A is a perspective view and FIG. 6B is a cross-sectional view corresponding to line AA in FIG. The difference from the eyewash device 10A of the first embodiment is that the convex portion 14b is not formed on the flat portion 14a of the knob portion 14, and the operational effects other than the convex portion 14b are the same as those of the first embodiment. . Even with only the flat portion 14a, the finger pad is in close contact with each other and is difficult to slip.

  FIGS. 7A and 7B show an eye washer 10D according to the fourth embodiment. FIG. 7A is a perspective view, and FIG. 7B is a cross-sectional view corresponding to the line AA in FIG. The difference from the eyewash device 10A of the first embodiment is that a concave portion 14c is formed in the flat portion 14a of the knob portion 14 in place of the convex portion 14b, and the operational effects thereof are the same as those of the first embodiment. is there. Even in the concave portion 14c, the finger pad bites in and becomes difficult to slip, as in the convex portion 14b.

  FIGS. 8A and 8B show an eyewash device 10E according to the fifth embodiment, in which FIG. 8A is a perspective view and FIG. 8B is a cross-sectional view corresponding to the line AA in FIG. What is different from the eyewash device 10A of the first embodiment is that the flat portion 14a of the knob portion 14 is not formed, and only a horizontally long elliptical convex portion 14b is formed, and other than the flat portion 14a. The effects are the same as in the first embodiment. Even with only this convex portion 14b, the finger pad bites in and becomes difficult to slip.

  FIGS. 9A and 9B show an eyewash device 10F according to the sixth embodiment, where FIG. 9A is a perspective view and FIG. 9B is a front view. The difference from the eyewash device 10A of the first embodiment is that the top portion 14d of the knob portion 14 is not hemispherical but flat, and the operation and effects thereof are the same as those of the first embodiment.

  The eyewashers 10G to 10I according to the seventh to ninth embodiments are embodiments in which the adapter 19 is subjected to anti-slip processing.

  11 and 12 show an eye wash 10G according to the seventh embodiment, FIG. 11 (a) is a perspective view, FIG. 11 (b) is a side cross-sectional view of the eye wash 10G set on a desk or the like 23, and FIG. Is a front sectional view in which the eyewash device 10G is set on a desk or the like 23, and (b) is a side sectional view of a modification.

  The adapter 19 is used when injecting eyewash from the bottle 17 (see FIG. 22) containing the eyewash into the liquid receiver 12 of the eyewasher 10G.

  That is, in the eyewashers 10A to 10F of the first to sixth embodiments, when the eyewash is injected into the liquid receiver 12 from the bottle 17 containing the eyewash, the other hand holds the eyewash 10A with one hand. Then, the eyewash solution bottle 17 must be grasped to inject the eyewash solution. In other words, you need to use both hands.

  Therefore, when the adapter 19 is placed on the desk 23 or the like at the time of liquid injection, the eyewash device 10G can be held in a substantially horizontal state.

  As a result, it is not necessary to hold the eyewash device 10A or the like with one hand, and the eyewash solution can be injected by grasping the bottle 17 containing the eyewash solution with one hand. In other words, it is not necessary to use both hands.

  In the eyewash device 10G of the seventh embodiment, the knob portion 14 is not slip-processed (the flat portion 14a, the convex portion 14b, and the concave portion 14c) [for example, the eyewash device 10E in FIG. 8A to the convex portion 14b. You can imagine what you removed]. In addition, the raw material and structure of eyewash 10G except the adapter 19 are the same as eyewashers 10A-10F of 1st-6th embodiment.

  And the adapter 19 which covers the outer periphery of the knob part 14 is integrally formed in the bottom part of the liquid receiving part 12 of the eyewasher 10G. Since the adapter 19 is formed integrally with the liquid receiving portion 12, it is a flexible material that can be elastically deformed as in the eyewash device 10G.

  The adapter 19 is anti-slip processed. As such an anti-slip process, the adapter 19 is formed in an elliptical shape in the same direction as the eyepiece 11, and a flat portion 19 a that is flat in the major axis direction of the eyepiece 11 is formed in a portion facing the adapter 19. .

  Each flat part 19a may be formed with a convex part 19b as shown in FIG. 13 or a concave part 19c as shown in FIG.

  When the flat portion 19a and the knob portion 14 of the adapter 19 are not joined, a gap S1 [see FIG. 11B] is generated in the range of the height T1, but in the range of the height T1, The flat part 19a of the adapter 19 and the knob part 14 can also be joined by adhesion, heat fitting, or the like.

  Further, as shown in FIG. 12B, the flat portion 19a of the adapter 19 and the knob portion 14 can be integrally formed within the range of the height T1.

  In the case of the eyewasher 10G configured as described above, the eyewasher 10G together with the adapter 19 is integrally formed of a flexible material that can be elastically deformed. Therefore, in the same manner as in FIG. After the eyewash is injected into the part 12 to the level WL and the eyewash part 11 is pressed around the eye 9 in the same manner as in FIG. 4B, the flat part 19a of the adapter 19 remains in the downward posture. When the knob portion 13 is pinched with the finger 9a and squeezed several times, the eyewash is stirred in the liquid receiving portion 12 with almost the same strength as the stirring water flow obtained by blinking in water. Become.

  In this way, it is possible to wash the eyes by simply pinching the knob portion 14 with the finger through the flat portion 19a of the adapter 19 and squeezing it, so it is necessary to blink in water that requires skill. Eliminates the convenience of use.

  In addition, since the adapter 19 is provided with a non-slip process (flat part 19a, convex part 19b, concave part 19c), the fingertip does not slip carelessly, so that the knob part 14 is easily squeezed and force is applied to the fingertip. Even without squeezing, you can squeeze smoothly with light force.

  Since the non-slip of the adapter 19 is formed by the flat portion 19a, the structure is simple and the finger pad is in close contact and is difficult to slip, and in addition, a convex portion 19b and a concave portion 19c are formed in the flat portion 19a. If you do this, the finger pad will bite and it will be difficult to slip. In addition, when pinching the knob part 14 via the adapter 19, it is good to set the length of the adapter 19 to the range of 15-25 mm.

  Further, since the entire eyewash device 10G is a flexible material (for example, elastomer) that can be elastically deformed, it has a soft touch, a good fit of the eyewash portion 13 and a pinch through the adapter 19 with a soft elasticity. The part 14 can be squeezed.

  Furthermore, since the eyewash device 10G is formed in a concave step shape by the eyepiece part 11, the liquid receiving part 12, the knob part 14, the adapter 19 and the like, the internal cleaning after use tends to be insufficient, and the dirt becomes dirty. Although the eyewasher 10G including the adapter 19 as a whole tends to accumulate, the eyewasher 10G is turned over together with the adapter 19 so that the inside can be completely cleaned. In addition, when the adapter 19 and the knob part 14 are not joined in the flat part 19a, it becomes easier to turn over the eyewasher 10G at the time of washing | cleaning. In addition, since the elastically deformable flexible material of the eyewash device 10G including the adapter 19 is heat resistant, even if it is boiled and disinfected from the hygiene aspect, it will not be plastically deformed.

  FIGS. 15A and 15B show an eyewash device 10H according to the eighth embodiment. FIG. 15A is a perspective view, and FIG. 15B is a side cross-sectional view in which the eyewash device 10H is set on a desk 23 or the like.

  In the seventh embodiment, as an anti-slip process for the adapter 19, the adapter 19 is formed in an elliptical shape and the flat portion 19 a is formed. However, in the eye washer 10 </ b> H of the eighth embodiment, the adapter 19 is a liquid receiving portion. The outer surface of the adapter 19 is formed with a convex portion 19b (or a concave portion 19c) as an anti-slip process, and its effect is the same as in the seventh embodiment. It is.

  Further, as shown in FIG. 16, the adapter 19 may be formed in a cylindrical shape having an outer diameter almost the same as the base portion of the knob portion 14. In this case, as shown in FIG. 17 (a), if the outer diameter of the knob portion 14 is matched with the inner diameter of the adapter 19, the adapter 19 comes into close contact with the knob portion 14, so the gap S1 [see FIG. 11 (b)]. Therefore, the knob portion 14 can be smoothly squeezed through the adapter 19. The adapter 19 and the knob portion 14 can be joined by bonding, heat fitting, or the like, or the adapter 19 and the knob portion 14 are integrally formed within the range of the height T1 shown in FIG. You can also

  As shown in FIG. 17 (b), if the adapter 19 is formed into a cylindrical shape having the same outer diameter as the liquid receiving portion 12, the gap S2 becomes wide. Therefore, the finger 9a is inserted into the gap S2 and the knob portion 14 is inserted. Can be squeezed directly. In this case, it is preferable to apply anti-slip processing to the knob portion 14, particularly the flat portion 14a, and the gap S2 becomes wider as the knob portion 14 is flat.

  18A and 18B show an eye wash 10I according to the ninth embodiment, where FIG. 18A is a perspective view, and FIG. 18B is a side cross-sectional view in which the eye wash 10I is set on a desktop 23 or the like.

  The difference from the eyewash device 10G of the seventh embodiment is that the flat portion 14a is applied to the knob portion 14. In addition, the flat part 19a of the adapter 19 and the flat part 14a of the knob part 14 can also be joined by adhesion | attachment, heat fitting, etc.

  FIG. 19 shows an eyewash device 10 </ b> J according to the tenth embodiment, in which an adapter 19 is integrally formed at the tip of the knob portion 14. The adapter 19 may have a circular shape, an elliptical shape, or other shapes in plan view. It is also possible that the knob portion 14 is not provided with anti-slip processing (the flat portion 14a, the convex portion 14b, and the concave portion 14c).

  Thus, when the adapter 19 is integrally formed at the tip of the knob part 14, the basin-shaped adapter 19 can hold the eyewash device 10J in a self-supporting state, and the knob part 13 is pinched with the finger 9a and squeezed. When the knob portion 13 slides from the finger 9a and tries to slide upward, the adapter 19 can be hooked under the finger 9a to prevent slipping.

  FIG. 20 shows a cylindrical adapter 19 according to an eleventh embodiment that can be used for the eyewashers 10A to 10F, and is provided as a separate member from the eyewashers 10A to 10F.

  The adapter 19 is not particularly limited in material, and is made of, for example, a thermoplastic resin, other synthetic resin, a natural material, thin paper or the like rolled into a cylindrical shape. Moreover, what was folded flatly can also be extended and used for a cylindrical shape.

  The adapter 19 is not particularly limited as long as the adapter 19 can achieve the purpose of holding the eyewasher 10A or the like in a self-supporting state, and the adapter 19 is fitted and held as shown in FIG. 20B.
