Description

Eye wash container

The present invention relates to an eyewash container formed in a cup shape and having a shape in which the periphery of the opening fits around the human eye.

Conventionally, in order to prevent eye disease and prevent hay fever, put the eyewash into a cup-shaped eyewash container, and face up with the periphery of the opening of the eyewash container in contact with the periphery of the human eye. It is known that the eye wash is performed by immersing the eye surface in an eye wash. Such an eyewash container is required to prevent leakage of eyewash liquid from a contact portion between the container and the face when the face is turned up.

Examples of such an eyewash container include those described in

Patent Documents

1, 2, or 3. The eye wash container disclosed in Patent Document 1 is formed so that the opening side of the peripheral wall portion extending from the bottom of the container is thinner than the bottom side in order to improve the feeling of adhesion when the eye wash container is pressed around the eye. ing.

In Patent Document 2, the peripheral wall of the eyewash container is composed of two members, a first peripheral wall rising from the bottom wall and a second peripheral wall fitted into the first peripheral wall, and the second peripheral wall is a soft elastic elastomer. A container for eyewash molded with is disclosed.

Patent Document 3 discloses an eyewashing container including a container main body and a flange portion, in which the container main body and the flange portion are integrally formed of the same material.
The thus formed eyewash container is generally sold together with the eyewash by covering the mouth of the bottle filled with the eyewash and covering with a shrink film or the like.

However, when the periphery of the opening is made thin like the eyewash container disclosed in Patent Document 1, the thin part creeps and deforms in the process of shrinking by covering the shrink film etc. from the outside of the container for sale. There was a problem that it was easy to do. In addition, since the periphery of the thin-walled portion becomes sharp at the time of manufacture, there is a possibility of causing pain when the eyewash container is pressed around the eyes. In addition, there is also a problem that it is difficult to form a thin portion as compared with the peripheral wall portion into which the eyewash is put. In addition, if the distance between the face-contacting part and the face is too short, there will be less part of the face in close contact with the face, which may cause the eyewash to leak during use, but if it is too long, the eyewash container will be pushed around the eyes. In addition, there is a problem that the eyes are pulled outward, and a decompressed state is easily generated in the container, causing pain in the eyes.

In addition, since the eyewash container described in Patent Document 2 is not integrally molded, dirt (for example, the remainder of the eyewash) accumulates at the step portion that is generated when the second peripheral wall is fitted into the first peripheral wall. There is a problem that it is easy. Since the eyewash container needs to be used in a sanitary manner, it is required to have a structure in which dirt is hardly left.

In addition, the circumference of a person's eyes is different on the eyelid side (upper side), eye corner side (outside), eye base side (inside), and cheek side (lower side), and dimensional design according to each part is required. However, Patent Documents 1 to 3 do not form a container in an appropriate shape for each part. Patent Document 3 discloses adjusting the width of the contact portion between the outer corner side and the eye side, but does not set the shape or size according to the portion where the distance or thickness of the contact portion contacts, No consideration is given to the heel and buccal areas of the eyes.

Therefore, the problem to be solved by the present invention is to provide an eyewash container that can further improve the adhesion to the periphery of human eyes and prevent liquid leakage.

In order to solve the above-described problems, an eyewash container of the present invention is an eyewash container formed in a cup shape, and the periphery of an opening is formed in a shape that fits around a human eye, and the eyewash container Has a bottom portion and a peripheral wall formed integrally with the bottom portion and extending upward from the periphery of the bottom portion, and an eyepiece portion extending outward from the upper end portion is formed on the upper end portion of the peripheral wall. The bottom part and the peripheral wall are formed of a first resin, the eyepiece part is formed of a second resin different from the first resin, and the second resin is formed of a first resin. Have different hardnesses (first aspect).

In the above invention, the hardness of the first resin is a value of R70 or higher or D40 or higher when measured based on JIS K 7202 (Plastics-Determination of hardness, Rockwell hardness). The thickness can be a value between 1 and 80 when measured based on JIS K 6253 (additive rubber and thermoplastic rubber—how to obtain hardness) (second mode).

In the said invention, it is preferable that the distance from the boundary part of a surrounding wall and an eyepiece part to the edge part of an eyepiece part shall be a value between 3 mm and 7 mm (3rd aspect).
In the above invention, the distance from the boundary between the peripheral wall and the eyepiece at the eye portion of the eyewash container to the edge of the eyepiece is the distance between the peripheral wall and the eyepiece at the outer corner of the eyewash container. It is a value larger than the distance from the boundary part to the edge part of the eyepiece part, and the eyepiece from the boundary part between the peripheral wall and the eyepiece part in the part between the eye base side part and the eye corner side part of the eye wash container The distance to the edge of the eye part is preferably equal to or greater than the distance from the boundary between the peripheral wall and the eyepiece in the eye-side part of the eyewash container to the edge of the eyepiece. (Fourth aspect).

In the above invention, the thickness of the eyepiece in the eye-side portion of the eyewash container is less than or equal to the thickness of the eyepiece in the eye corner side portion of the eyewash container. The thickness of the eyewash container in the portion between the eye-side portion and the eye corner-side portion of the eye wash container may be configured to be thinner than the wall thickness in the eye-side portion and the wall thickness in the eye-ear side portion (fifth aspect). .

In the above invention, the eyepiece formed from the second resin may have a color tone different from that of the bottom and the peripheral wall formed from the first resin (sixth aspect).
In the said invention, the boundary part of the surrounding wall and eyepiece part in the inner surface of the container for eyewash may be formed substantially flush (seventh aspect).

The bottom part and the peripheral wall may have higher transparency than the eyepiece part (eighth aspect).

According to the first aspect, the bottom and the peripheral wall of the eyewash container including the bottom, the peripheral wall, and the eyepiece are formed from the first resin, the eyepiece is formed from the second resin, and the second resin. Is made softer than that of the first resin, so that the adhesion when the eyepiece is brought into contact with the periphery of the eye can be improved. In addition, since the eyewash container is formed integrally, the manufacturing process can be reduced and the structure of the container can be simplified as compared with a multi-part container, and the time required for manufacturing can be reduced. In addition, the cost can be reduced. Further, in the case of a container having a multi-part configuration, there is a possibility that the eyewash liquid may accumulate in these connecting portions. However, since the eyewash container is integrally formed in this aspect, such a problem does not occur.

According to the second aspect, the hardness of the first resin when measured based on JIS K 7202 is set to a value of R70 or higher or D40 or higher, and the hardness of the second resin when measured based on JIS K 6253. Since the thickness is set to a value between 1 and 80, it is possible to further improve the close contact feeling when the eyepiece is brought into contact with the periphery of the eye.

According to the third aspect, since the distance from the boundary between the peripheral wall and the eyepiece to the edge of the eyepiece is set to a value between 3 mm and 7 mm, the distance is too short or too long. Thus, it is possible to improve the adhesion between the eye periphery and the eyewash container while eliminating the conventional problems.

According to the fourth aspect, the distance from the boundary portion between the peripheral wall and the eyepiece portion in the eyepiece side portion of the eyewash container to the edge portion of the eyepiece portion is set to the peripheral wall and eyepiece in the eyelid side portion of the eyewash container. From the boundary part between the peripheral wall and the eyepiece part in the part between the eye side part and the eye corner side part of the eye wash container, with a value larger than the distance from the boundary part to the edge part of the eyepiece part The distance to the edge of the eyepiece is equal to or greater than the distance from the boundary between the peripheral wall and the eyepiece in the eyepiece side portion of the eyewash container to the edge of the eyepiece To do. Therefore, by setting the distance at the corner of the eye corner where eyewash is most likely to leak to the shortest, the deformation of the container at the corner of the corner of the eye during use can be reduced or suppressed compared to other portions. As a result, it is possible to effectively prevent the eyewash from leaking at the outer corner of the eye.

According to the fifth aspect, the thickness of the eyepiece portion in the eye portion side portion of the eye wash container is made thinner or the same as the wall thickness of the eye portion in the eye corner side portion of the eye wash container, and the eye side portion of the eye wash container The thickness of the eyewash container in the portion between the eye corner and the eye corner side portion is made thinner than the wall thickness in the eye side portion and the eye corner side portion. The thickness of the container can be made the smallest so that the deformation of the container at the outer corner portion can be reduced or suppressed as compared with other portions. As a result, it is possible to effectively prevent the eyewash from leaking at the outer corner of the eye.

According to the sixth aspect, the eyepiece formed from the second resin has a color tone different from that of the bottom and the peripheral wall formed from the first resin. Even in this case, it is possible to prevent the eyewash container from becoming difficult to see, and to reliably recognize the opening for putting the eyewash into the container without overflowing the eyewash.

According to the seventh aspect, since the boundary portion between the peripheral wall and the eyepiece portion on the inner surface of the eyewash container is formed to be substantially flush, for example, eyewash liquid after eye washing, removed dust, etc. are accumulated in the boundary portion. Can be prevented.

According to the eighth aspect, the bottom and the peripheral wall are made more transparent than the eyepiece, so that the dirt removed from the eyes by eye washing can be visually confirmed, and the container can be hygienicly washed and stored. It becomes.

It is a side view which shows the container for eyewash which concerns on the 1st Embodiment of this invention. It is a side view of the container for eyewash for demonstrating the distance from the boundary part of the surrounding wall shown in FIG. 1, and the upper edge part of an eyepiece part. FIG. 3 (a) is a side view for explaining an eyewash container according to a second embodiment of the present invention, and FIG. 3 (b) is a sectional view taken along line AA in FIG. 3 (a). 3C is a front view of the eyewash container shown in FIG. 3A, and FIG. 3D is a cross-sectional view taken along line BB in FIG. 3C. It is explanatory drawing which shows an example of a color tone standard value.

The eyewash container of the present invention will be specifically described below with reference to the drawings. First, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.
FIG. 1 is a side view showing an example of an eyewash container according to the first embodiment. The eyewash container in the present embodiment is formed in a cup shape for containing an eyewash, and the peripheral edge of the container opening is formed in a shape that fits around the human eye.

More specifically, as shown in FIG. 1, the eyewash container 1 has a bottom portion 2 and a peripheral wall 3 extending upward from the periphery of the bottom portion 2, and is formed in a cup shape as a whole with the upper portion opened. Yes. An eyepiece 4 extending outward from the upper end is provided at the upper end of the peripheral wall 3, and the opening peripheral edge of the eyewash container 1 is defined by the eyepiece 4. In the present embodiment, the bottom 2, the peripheral wall 3, and the eyepiece 4 of the eyewash container 1 are integrally formed.

In the present embodiment, the bottom 2 and the peripheral wall 3 are made of a first resin, such as a thermoplastic resin, and the eyepiece 4 is different from the first resin, such as a thermoplastic elastomer, for example. The second resin is softer than the other resin. As the thermoplastic resin, it is preferable to use polypropylene or polyethylene. As the thermoplastic elastomer, a styrene elastomer is preferably used. Since the styrene elastomer has good adhesiveness with a thermoplastic resin such as polypropylene used as the first resin at the time of molding, it contacts with the boundary portion 5 between the eyepiece 4 and the peripheral wall 3 during use. The eye part 4 is not broken and separated from the peripheral wall 3.

Thus, by making the eyepiece 4 with the second resin softer than the first resin of the bottom 2 and the peripheral wall 3, the adhesion when the eyepiece 4 is brought into contact with the periphery of the eye is improved. Can be made. In addition, the manufacturing process can be reduced and the configuration of the container 1 can be simplified as compared with the multi-component container as described in the prior art, and the time and cost for manufacturing can be reduced. It can be reduced. Further, in the case of a container having a multi-part structure, there is a possibility that the eyewash liquid may accumulate in these connecting portions. However, since the eyewash container is integrally formed in this aspect, such a problem does not occur.

The first resin of the bottom part 2 and the peripheral wall 3 has, for example, a hardness of R70 or higher or D40 or higher when using the measurement method of JIS K 7202 (Plastic-Hardness calculation, Rockwell hardness). R80 or higher or D40 or higher is more preferable, and R90 or higher or D40 or higher is most preferable. The second resin of the eyepiece 4 has a hardness of, for example, 1 point or more and 80 points or less when using the measurement method of JIS K 6253 (additive rubber and thermoplastic rubber-how to obtain hardness). It is preferable that the hardness is 30 points or more and 80 points or less, and the hardness is 40 points or more and 55 points or less is most preferable. That is, by making the hardness of the second resin softer than the hardness of the first resin, it is excellent in adhesion to the periphery of the eye without making the eyepiece portion thin as a whole as described in the prior art. An eyewash container 1 can be obtained. Further, by setting the hardness of the first resin to R70 or more or D40 or more in JIS K 7202, even if the user presses the eyewash container 1 with a finger during use, the peripheral wall 3 portion is not easily deformed. Accordingly, it is possible to prevent the eyewash liquid from leaking from the container 1 due to deformation of the eyewash container 1 during use.

As shown in FIG. 1, the upper edge 4 </ b> A of the eyepiece 4 from the length of the eyepiece 4, that is, the extension line of the boundary portion 5 between the peripheral wall 3 and the eyepiece 4 in the side view of FIG. 1. The distance L is preferably 1 to 7 mm, more preferably 2 to 7 mm, and most preferably 3 to 7 mm. In the eyewash container, if the distance L from the extension line of the boundary portion 5 between the peripheral wall 3 and the eyepiece 4 to the upper edge 4A of the eyepiece 4 is too long, the adhesion to the periphery of the eye is enhanced. However, if it is too close, it will feel like the eye pops out, making it difficult to wash the eye. On the other hand, it is preferable to set the distance L within the above range in order to obtain appropriate adhesion to the periphery of the eye.

The distance L from the boundary portion 5 between the peripheral wall 3 and the eyepiece 4 described above to the upper edge 4A of the eyepiece 4 is desirably different depending on the site of the eyewash container 1. FIG. 2 is a side view of the eyewash container 1 for explaining the distance from the boundary portion 5 between the peripheral wall 3 and the eyepiece 4 shown in FIG. 1 to the upper edge 4A of the eyepiece 4. For the sake of explanation, the distance from the boundary part 5 between the peripheral wall 3 and the eyepiece part 4 in the eyepiece side part 1A of the eyewash container 1 to the upper edge part 4A of the eyepiece part 4 is A, the outer corner side of the eyewash container 1 The distance from the boundary part 5 between the peripheral wall 3 and the eyepiece part 4 to the upper edge part 4A of the eyepiece part 4 in the part 1B is B, and the part between the eye side part 1A and the eye corner side part 1B of the eyewash container 1 Let C be the distance from the boundary portion 5 between the peripheral wall 3 and the eyepiece 4 at 1C to the upper edge 4A of the eyepiece 4. As is apparent from the drawing, the distance C is defined as the horizontal line when the horizontal line and the boundary part 5 contact each other in FIG. 2 and the upper edge of the eyepiece part 4 when the horizontal line is translated upward in FIG. In other words, it can be rephrased as the distance between the tangent and the horizontal line. In the present embodiment, the distance A in the eye-side part 1A of the eyewash container 1 is the distance from the boundary part 5 between the peripheral wall 3 and the eyepiece part 4 in the outer corner part 1B of the eyewash container 1 above the eyepiece part 4. It is formed longer than the distance B to the edge 4A. Further, the distance C from the boundary portion 5 between the peripheral wall 3 and the eyepiece portion 4 to the upper edge portion 4A of the eyepiece portion 4 in the portion 1C between the eye side portion 1A and the eye corner side portion 1B of the eyewash container 1 is The distance A from the boundary portion 5 between the peripheral wall 3 and the eyepiece portion 4 in the eye portion 1A of the eyewash container 1 is equal to or longer than the distance A from the upper edge portion 4A of the eyepiece portion 4. That is, the distances A, B, and C in each part of the eyepiece 4 are
B <A ≦ C
The dimensions are designed so that this relationship is established.

Thus, among the eyepieces 4 of the eyewash container 1, by sizing the distance B in the eye corner side portion 1 </ b> B of the eyewash container 1, the eye corner side where leakage of the eyewash is most likely to occur is determined. It is possible to reliably prevent the liquid leakage of the eye wash 4 in the portion 1B.

Since the peripheral wall 3 is formed of the first resin and the eyepiece 4 is formed of the second resin, the first resin and the second resin are formed in the region where the first resin is transferred to the second resin. In the present invention, the portion where the first resin and the second resin overlap is not included in the length (distance), and the length of the portion where only the second resin exists is present. It is intended to adjust the (distance) dimension.

As described above, according to the present embodiment, since the second resin forming the eyepiece 4 of the eyewash container 1 is softer than the first resin of the bottom 2 and the peripheral wall 3, It is possible to provide an eyewash container having excellent adhesion to the periphery of the eye without making the entire eye part 4 thin. Further, since the bottom portion 2, the peripheral wall 3, and the eyepiece portion 4 are integrally formed, there is no possibility that the eyewash liquid is accumulated in the connection portion as in the case of a multi-part configuration, and the container can be used hygienically. In addition, the configuration of the container can be simplified, the number of manufacturing steps can be reduced, and the manufacturing time and cost can be suppressed. Further, by sizing the distance B at the outer corner portion 1B where the eyewash is most likely to leak out of the eyepiece portion 4 of the eyewash container 1, the deformation of the container at the outer corner portion 1B during use can be reduced. Less or less than the portion. Therefore, it is possible to effectively prevent the eyewash liquid from leaking at the outer corner of the eye.

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 3 is a diagram showing a configuration of the eyewash container according to the present embodiment, and FIG. 3A is a left side view for explaining the eyewash container according to the second embodiment of the present invention. 3B is a cross-sectional view taken along line AA in FIG. 3A, FIG. 3C is a front view of the eyewash container shown in FIG. 3A, and FIG. It is sectional drawing in line BB of c). In FIG. 3, the same reference numerals are given to the components corresponding to the configurations shown in FIGS. 1 and 2 of the first embodiment.

In the first embodiment described above, the distance B from the boundary portion 5 between the peripheral wall 3 and the eyepiece portion 4 to the upper edge portion 4A of the eyepiece portion 4 in the corner of the eye corner where the eyewash liquid is liable to leak is different. By making the distance shorter than the distances A and C in this portion, the eyepiece 4 is less likely to be deformed in the outer corner portion 1B. On the other hand, in this embodiment, the eye wash liquid from the eye corner side portion 1B is set by appropriately setting the thickness of the eyepiece portion 4 at the eye side portion 1A, the eye corner side portion 1B, and the intermediate portion 1C thereof. This is to prevent leakage.

More specifically, as shown in FIG. 3 (d), the thickness TA of the eyepiece 4 in the eye-side portion 1A is slightly less than or equal to the thickness TB of the eyepiece 4 in the outer corner portion 1B. is there. Further, as apparent from FIGS. 3B and 3D, the thickness TC of the eyepiece 4 in the portion 1C between the eye side portion 1A and the eye corner side portion 1B is the thickness of the eye side portion 1A. The thickness is made smaller than TA and the thickness TB of the outer corner 1B. That is, the thickness of the eyepiece 4 in each part is set as follows.

TC <TA ≦ TB
According to the present embodiment, by designing the thickness of the eyepiece portion as described above, the eyewash portion 4 is deformed more easily than the other portions in the eye corner side portion 1B, which is likely to cause the eyewash to leak. It becomes difficult to occur. Accordingly, it is possible to prevent the eyewash from leaking from the outer corner portion 1B.

As shown in FIG. 3, the thickness of the eyepiece part 4 in the eye side part 1A, the eye corner side part 1B, and the intermediate part 1C thereof is preferably 0.5 to 2.5 mm, more preferably 0. It is 5 to 2.0 mm, and most preferably 0.5 to 1.5 mm.

In addition, it cannot be overemphasized that the thickness relationship of the eyepiece part mentioned above as 2nd Embodiment is applicable with respect to the container for eyewash demonstrated in 1st Embodiment.
Next, a third embodiment of the present invention will be described with reference to FIG. In the present embodiment, in the eyewash container 1 described as the first and second embodiments described above, the eyepiece 4 made of the second resin is replaced with the first resin that constitutes the bottom 2 and the peripheral wall 3. It has a different color tone.

Here, “color tone” can be measured with a color checker (KONIKA MINOLTA CHROMA METER CR-5). When expressed in the colorimetric CIE * L * a * b * color system, the first resin is preferably colorless and transparent, and the value of L *, which is an indicator of brightness (a light color that is nearly colorless when the value is large) 85, preferably over 90, more preferably over 90, and the value of a * b *, which is an indicator of hue and saturation, is preferably close to 0, 5 or less is preferable and 3 or less is more preferable. On the other hand, the second resin is preferably colored and semi-transparent to opaque, and the L * value is preferably 50 or less, more preferably 35 or less, and the a * b * value is not particularly limited. It is possible to set appropriately. For example, in red, the value of L * a * b * is L * = 25.00-35.00, a * = 3.00-20.00, b * = − 3.00-3.00 Is desirable. In addition, the color of the eyepiece 4 formed of the second resin is not limited to red as long as the color is different from the bottom and the peripheral wall formed of the first resin, and is made of the second resin. Needless to say, colors such as blue, green, and orange can be adopted as long as the color can be clearly identified.

If the color tone of the eyepiece 4 formed of the second resin is different from that of the bottom 2 and the peripheral wall 3 of the eyewash container 1 formed of the first resin, for example, the eyewash is removed by removing contact lenses and glasses. , It is possible to clearly recognize the peripheral edge of the opening of the container 1 that is difficult to identify with the naked eye by the eyepiece 4. This prevents the cup from becoming difficult to see even when the contact lens or glasses are removed during eyewash, and ensures that the opening for filling the eyewash is recognized and poured into the container without overflowing the eyewash. Will be able to.

Note that the color tone change according to the part as in the present embodiment is also applicable to the first and second embodiments described above.
Next, a fourth embodiment of the present invention will be described. As described above, since the eyewash container needs to be used hygienically, it is required to have a structure in which dirt does not easily remain. Therefore, in the present application, the entire container is integrally formed, but in the present embodiment, a condition is further set in which the boundary portion between the peripheral wall and the eyepiece portion on the inner surface of the eyewash container is formed flush. Here, in the present invention, “level” means a state where the step between the eyepiece 4 and the peripheral wall 3 in the boundary portion 5 is ± 0.1 mm or less. By comprising in this way, it becomes possible to prevent the eyewash after eyewashing, the removed dust, etc. from accumulating in a boundary part, and to use a container hygienically.

Next, a fifth embodiment of the present invention will be described. As described above, the eyewash container 1 needs to be hygienic for the purpose of use. However, when the bottom 2 and the peripheral wall 3 of the eyewash container 1 are translucent or opaque, the eye wash actually Since it is difficult to visually confirm dirt such as dust removed from the container, there is a problem that it is not known whether the eyewash liquid in the container 1 is in a dirty state or is washed. Therefore, in the present embodiment, the bottom 2 and the peripheral wall 3 are made of a transparent material having high light transmittance. Transparent materials with high light transmission are, for example, JIS K 7136 (how to determine haze of plastic transparent material), JIS K 7361-1 (plastic-test method of total light transmittance of transparent material-Part 1, single beam method ), Or JIS K 7375 (Plastics—How to obtain total light transmittance and total light reflectance), etc. can be employed. When the single beam method is used, in the present embodiment, the transparency of the bottom 2 and the peripheral wall 3 is preferably, for example, a specimen thickness of 50 μm and a transmittance of 85% or more, and more preferably 90% or more.

By adopting such a highly transparent bottom 2 and peripheral wall 3, the user can easily check the dirt in the container. Of course, the bottom 2 and the peripheral wall 3 configured as in the present embodiment can be employed in the first to fourth embodiments.

As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, A various change is possible unless it deviates from the meaning.

Examples of the present invention will be described below. However, the present invention is not limited to this example.
A specific molding method of this aspect is the method of injection molding the first resin in the mold on the temporary molding side, molding the peripheral wall portion and the bottom portion, and then taking out a molded product composed of the formed peripheral wall portion and bottom portion, This is a general two-color molding method in which an eyepiece is formed by setting a secondary molding side mold and injection molding a second resin.

Here, samples of Examples 1 to 5 according to the present invention and samples of Comparative Examples 1 and 2 to be compared therewith were prepared. Here, an eyewash container as shown in FIG. 1 was prepared, the hardness of the material constituting the container was changed, and samples having the same conditions were prepared except for that. The specifications of each sample are as shown in Table 1 below. The eyewash container of Comparative Example 2 is formed by integrally molding the bottom portion, the peripheral wall portion, and the eyepiece portion with only the first resin.

From the above results, if the second resin is soft, there is a feeling that the eyes are pulled to some extent, but the eyewash does not leak. On the other hand, when the hardness of the second resin was too hard, the fit feeling deteriorated and leakage of the eyewash was recognized. Moreover, leakage of the eyewash was also observed when the bottom part, the peripheral wall part, and the eyepiece part were integrally formed with only the first resin. Therefore, by setting the hardness of the first resin and the second resin so that the thickness of the eyepiece part and the length of the eyepiece part are within the predetermined ranges as in Examples 1 to 5, liquid leakage is prevented. And a moderate fit can be obtained.
