Description

  The present invention relates to an eyewash container formed in a cup shape.

  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.

  Examples of such an eyewash container include those described in Patent Documents 1 and 2. The eye wash container disclosed in Patent Document 1 is pre-filled with an eye wash solution in the eye wash container, and the eye contact surface of the eye wash container is pressed around the eyes, and the face is faced upward in that state. Is. In Patent Document 1, 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 inside the first peripheral wall. In use, the second peripheral wall is the first peripheral wall. Used by being fitted inside.

  Further, Patent Document 2 discloses an eyewashing container including a container main body and a flange portion, in which the flange portion is formed thin. In Patent Document 2, a rib 6 extending to the upper surface of the bottom wall is formed on the inner peripheral surface of the eyewash container, and this rib holds the mouthwash when the eyewash bottle is attached to the mouth. The

  Moreover, there exist what was shown in FIG. 1 in the container for eyewash conventionally used. This eyewash container has a bottom wall and a peripheral wall extending upward from the periphery of the bottom wall, and is provided with a pair of protrusions each extending from the peripheral wall toward the inside of the container.

  However, since the eyewash container described in Patent Document 1 has a two-part structure and the entire container is not integrally molded, the stepped portion that is generated when the second peripheral wall is fitted into the first peripheral wall is formed. There is a problem that dirt (for example, the remainder of the eyewash) tends to accumulate. 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.

  Further, the container for eyewash of Patent Document 2 is intended to achieve stability on the eyewash bottle by the rib, but it is approximately 90 degrees between the rib and the bottom wall and between the rib and the peripheral wall. A corner portion is formed, and there is a problem that dirt easily accumulates in this portion.

Moreover, since each protrusion part shown in FIG. 1 was comprised from two ribs, there existed a tendency for dirt to collect easily in the clearance gap between the ribs.
Accordingly, the problem to be solved by the present invention is to provide an eyewash container without a structure in which dirt tends to accumulate.

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 is formed integrally with a bottom wall and the bottom wall and upward from a peripheral edge of the bottom wall. And an upper edge of the peripheral wall defines a periphery of the opening of the eyewash container, and a periphery of the opening of the eyewash container is adapted to fit around a human eye. In the eyewash container
The bottom wall is provided with at least a pair of convex portions having a rounded surface protruding toward the inside of the container (first aspect).

In the above invention, it is desirable that the convex portion is formed from the periphery of the bottom wall toward at least a part of the peripheral wall toward the inside of the eyewash container (second aspect).
The eyewash container of the present invention is an eyewash container formed in a cup shape, and includes a bottom wall and a peripheral wall formed integrally with the bottom wall and extending upward from the periphery of the bottom wall. An eye wash container in which an upper edge of the peripheral wall defines a periphery of an opening of the eye wash container, and a periphery of the opening of the eye wash container is adapted to fit around a human eye A perforation line for measuring the amount of the eyewash liquid is formed on the outer peripheral surface of the peripheral wall (third aspect).

  The eyewash container of the present invention is an eyewash container formed in a cup shape, and includes a bottom wall and a peripheral wall formed integrally with the bottom wall and extending upward from the periphery of the bottom wall. An eye wash container in which an upper edge of the peripheral wall defines a periphery of an opening of the eye wash container, and a periphery of the opening of the eye wash container is adapted to fit around a human eye The inner corner formed by the peripheral edge of the bottom wall and the peripheral wall is rounded (fourth aspect).

  According to the first aspect, since the rounded convex portion protruding from the bottom wall toward the inside of the container is provided, when the eyewash container is fitted to the mouth portion of the eyewash bottle as in the prior art In addition, since only a pair of convex portions is provided, it is possible to eliminate the conventional structure in which dirt existing between two ribs tends to accumulate.

  According to the second aspect, the convex portion is formed from the peripheral edge of the bottom wall toward the inside of the eyewash container over at least a part of the peripheral wall. A portion where dirt easily accumulates is not formed between the portion and the peripheral wall.

  In addition, according to the third aspect, since the perforation line for measuring the amount of the eyewash liquid is formed on the outer peripheral surface of the peripheral wall, conventionally, it has been provided on the inner surface of the eyewash container due to manufacturing problems. Thus, it becomes possible to eliminate the measurement line of lines where dirt easily collects from the inside of the container.

  Further, according to the fourth aspect, since the inner corner portion formed by the peripheral edge and the peripheral wall of the bottom wall is rounded, the angularity formed by the peripheral edge portion and the peripheral wall of the bottom wall where dirt easily collects. It is possible to easily remove the dirt even if it gets dirty. Further, since the thickness is increased by providing the roundness, it is possible to prevent deformation when gripping the eyewash container, and it is possible to prevent leakage of the eyewash liquid from the eyewash container due to deformation. Further, by providing the roundness, it becomes possible to suppress the remaining of the eyewash liquid and the liquid such as water when the eyewash container itself is washed from adsorbing to the inner corner portion due to the surface tension thereof. This facilitates the removal of the liquid, enables the eyewash container to be dried in a short time, and suppresses the growth of microorganisms due to the presence of the liquid.

FIG. 2 (a) is a plan view, FIG. 2 (b) is a left side view, and FIG. 2 (c) is FIG. 2A is a cross-sectional view taken along the line AA in FIG. 2, FIG. 2D is a front view of the eyewash container, FIG. 2E is a cross-sectional view taken along the line BB in FIG. 2D, and FIG. FIG. 3 is a cross-sectional view for explaining details of the eyewash container shown in FIG. 2, and FIGS. 4A and 4B are views for explaining the eyewash container shown in FIG. It is a left side view and a front view. 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 FIGS. 2A to 2F, the eyewash container 1 has a bottom wall 2 and a peripheral wall 3 extending upward from the peripheral edge of the bottom wall 2. It is formed in a cup shape as a whole. An eyepiece 4 extending outward from the upper end is provided at the upper end of the peripheral wall 3, and the periphery of the opening of the eyewash container 1 is defined by the eyepiece 4. In the present embodiment, the bottom wall 2, the peripheral wall 3, and the eyepiece 4 of the eyewash container 1 are integrally formed. The bottom wall 2, the peripheral wall 3, and the eyepiece 4 may each be molded with the same resin, or may be molded with different resins. The bottom wall 2 and the peripheral wall 3 may be molded from the same resin, and the eyepiece 4 may be molded from a resin different from the bottom wall 2 and the peripheral wall 3. In this case, the bottom wall 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, 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 styrenic elastomer has good adhesion to a thermoplastic resin such as polypropylene used as the first resin during molding, the eyepiece is used at the boundary between the eyepiece 4 and the peripheral wall 3 during use. The portion 4 is not broken and separated from the peripheral wall 3.

  Thus, by manufacturing the eyepiece 4 with the second resin that is softer than the first resin of the bottom wall 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 improved. In addition, the number of manufacturing steps can be reduced and the configuration of the container 1 can be simplified as compared with a multi-component container, and the time and cost for manufacturing 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 wall 2 and the peripheral wall 3 has a hardness of, for example, R70 or higher or D40 or higher when using the measurement method of JIS K 7202 (Plastics-How to determine hardness 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, the eyewash container 1 having excellent adhesion to the periphery of the eyes is obtained without making the eyepiece part thin as a whole. be able to. 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 hardly 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.

  In the present embodiment, a projecting portion 5 extending upward from at least a part of the peripheral wall 3 along the peripheral wall 3 from the bottom wall 2 is formed. A plurality of projecting portions 5 projecting inward from the peripheral wall 3 of the eyewash container 1 are provided. In FIGS. 2A and 2E, as an example, a pair of protrusions 5 are provided 180 degrees apart from each other, but the number of protrusions 5 is not limited to two. If the stability of the eyewash container 1 on the bottle can be achieved, it is possible to provide three or more protrusions. The protrusion 5 has the same function as the fitting rib when the eyewash container 1 is fitted to the cap portion of the eyewash bottle in the conventional example described with reference to FIG. That is, each protrusion 5 has a predetermined width (FIG. 2 (c)) and thickness (FIG. 2 (e)), and protrudes when the eyewash container 1 is fitted to the mouth of the eyewash bottle. The size is set so that the mouth is stably received between the parts 5. However, as shown in FIG. 2, the protruding portion of this embodiment does not have a gap between ribs as in the prior art, and there is no gap between the rib and the bottom wall and between the rib and the peripheral wall. Therefore, it is possible to reduce the structure in which dirt accumulates around the protruding portion 5 fitted to the cap of the bottle.

  FIG. 3 is a cross-sectional view for explaining the shape of the bottom wall 2 portion in the cross-sectional view shown in FIG. In FIG. 3, the description of the peripheral edge portion of the opening of the container 1 is omitted. As shown in the figure, the corner portion formed between the bottom wall 2 and the protruding portion 5 is not a right angle but slightly rounded. The roundness (R) is preferably about 1 to 6 (unit: mm). Although the corner portion formed between the bottom wall 2 and the protruding portion 5 has been described, the corner portion formed between the peripheral edge of the bottom wall 2 and the peripheral wall 3 and between the peripheral wall 3 and the protruding portion 5 is also described. It is possible to provide the roundness (R).

  As is apparent from FIG. 4, the eyewash container 1 of the present embodiment is provided with a metering line 6 on the outer periphery of the peripheral wall. The perforation line 6 is formed by a recess having a depth that fits within the wall thickness of the peripheral wall 3 with R being about 0.3 mm to 2.0 mm. In addition, the entry line 6 can be formed not as a recess in the peripheral wall 3 but as a convex portion or a stepped portion protruding to the outside of the peripheral wall 3. Conventionally, for the reason of the manufacturing process, it has been necessary to provide the entry line on the inner surface side of the peripheral wall 3 of the eyewash container 1, and there is a problem that dirt easily collects. On the other hand, it is possible to remove the structure in which dirt easily accumulates from the inside of the container 1 by providing the eye line 6 entering the outside as in the present embodiment.

  The eyewash container 1 needs to be hygienic for the purpose of use, but when the bottom wall 2 and the peripheral wall 3 of the eyewash container 1 are translucent or opaque, they are actually removed from the eyes by eyewash. Since it is difficult to visually check dirt such as dust, there is a problem that it is not known whether the eyewash in the container 1 is in a dirty state or being washed. Therefore, in the present embodiment, the bottom wall 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 materials), JIS K 7361-1 (plastics-test method of total light transmittance of transparent materials-part 1, single beam method Alternatively, JIS K 7375 (Plastic—Method of obtaining total light transmittance and total light reflectance, etc. can be employed. When the single beam method is used, the transparency of the bottom wall 2 and the peripheral wall 3 in this embodiment is used. Is, for example, a specimen thickness of 50 μm and a transmittance of 85% or more, preferably 90% or more.

By adopting such a highly transparent bottom wall 2 and peripheral wall 3, the user can easily check the contamination in the container.
The embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. Of course, the first to fourth embodiments can be used in combination.
