Description

  The present invention relates to an eye wash container for washing an eye with an eye wash.

  Conventionally, eye washing has been performed exclusively at medical institutions, but in recent years, eye wash containers that can be freely and easily performed by those who want to wash their eyes are commercially available. As such an eyewash container, for example, a predetermined amount of an eyewash solution is injected into a flexible resin eyewash container, the eyewash container is pressed against the face eye, and in this state, the eyewash is turned upward. The eye is washed with an eye wash (for example, see Patent Document 1).

  However, the container for eyewash of such a use form is made of a container having flexibility, but it is not possible to make it adhere in a state in which it is fitted to the face eyes of all people who have various face shapes. It is difficult, and there is a risk that the eyewash leaks out during eyewash and stains clothes and the like through the face. Thus, as a solution to this type of problem, an eyewash container has been developed that can wash the eye with an eyewash while facing downward during eyewashing (see, for example, Patent Documents 2 and 3).

  The eyewash container disclosed in Patent Document 2 extends a cap-shaped squeezing part from the cylinder part, injects eyewash into the squeezing part, and presses the squeezing part by bringing the cylinder part into close contact with the face area. As a result, the liquid level of the eyewash is raised so that the eyes can be immersed and washed, and there is almost no risk of soiling clothes etc. with the eyewash. Therefore, when the eyewash is poured into the squeezing part, the eyewash operation must be continuously performed because it cannot be placed in a standing state without spilling the liquid on something. There is a problem that there is no room and it is somewhat annoying.

Further, the eyewash container disclosed in Patent Document 3 is configured such that at least a part of the bottom wall is made thinner than the side wall, and this part is easily elastically deformed by pressing the thin part from the outside. There is no risk of soiling clothes and the like with the eyewash, but by pressing the thin wall portion of the bottom wall, the liquid level of the eyewash is raised so that the eye can be immersed and washed. Therefore, the amount of deformation of the bottom wall is small, and the amount of eyewash used at one time must be larger than that of the eyewashing containers of Patent Documents 1 and 2. There is a problem that is accompanied by difficulties.

  Further, the present invention according to claim 6 is the eyewash container according to any one of claims 1 to 5, wherein a circumferential step is provided between the peripheral wall portion for covering and the cylindrical portion for liquid reservoir. It is characterized by being. By configuring in this way, when the peripheral walls at positions facing each other across the substantially inverted U-shaped bottom wall of the liquid storage tubular portion are repeatedly pressed so as to approach each other, the pressing force is applied to the coating peripheral wall. Since the deflection of the peripheral wall portion for covering due to propagation to the portion can be reduced, liquid leakage from the peripheral wall portion for covering during eye washing can be prevented.

  Since the eyewash container of the present invention has a configuration having a bottomed liquid storage tubular portion, the eyewash solution can be placed in a standing state without spilling the liquid in a state where the eyewash solution is injected. The eye can be washed with a sufficient time, and the liquid level can be reduced by repeatedly pressing the peripheral walls in positions facing each other across the substantially U-shaped bottom wall in cross section of the cylindrical portion for liquid reservoir. Because it can be moved up and down, it is possible to wash the eyes with the face facing down, and at the time of washing the eyes, the clothes etc. are not soiled with the eyewash, and the eyes can be washed with one hand so that the eyes can be washed easily. Furthermore, since the liquid storage tubular portion is substantially divided into two by a substantially inverted U-shaped bottom wall, it has excellent effects such as being able to wash the eyes with a small amount of eyewash. It is what you play.
