Description

[Detailed explanation of the idea] "Industrial application field" This case concerns eyewash devices.

``Prior Art'' Eyewash supplies usually consist of a container for storing a medicinal solution and a small cup.Eyewashing involves pouring the medicinal solution in the container into the small cup, and then pressing the area around the eye against the top of the cup. This is done by applying the technique, then turning your face upward and blinking your eyes.

"Problems to be Solved by the Invention" The above-mentioned conventional example takes a long time to wash the eyes and is not sufficiently effective. Furthermore, since it is divided into a container for storing the medicinal solution and a small cup, it is possible to forget to carry either the container or the small cup when carrying it to the beach or the like.

The present invention is formed so that the medicinal solution can be squirted upward by pressing a part of the eyewash device,
This makes it possible to wash the eyes easily, reliably and quickly, and also makes it convenient to carry by attaching a small cup to the drug solution storage container.

"Means for Solving the Problems" A container body 1 has a mouth and neck part 2 erected from the upper end of a body part 2 that can be elastically compressed, and a lower part of a cylinder 5 is fitted to the outer surface of the mouth and neck part 2, and A tube portion 9 having a closed upper end face and having small through holes 10 . 5 an eyewash member 4 having a lid 11 removably fitted on the upper end thereof and connected to the cylinder 5 via a band 12; and the tube 9.
, a drug solution outflow pipe 13 into which the upper part of the pipe hanging down to the bottom of the container body is fitted, and the eyewash member 4
A check valve 14 is provided on the inward flange-shaped wall 7 to allow the medical solution inside to flow into the container body.

"Operation" From the illustrated state, when the lid 11 is opened and the area around the eyes is pressed against the upper end of the cylinder 5 to squeeze the container body 2, the check valve 14 closes and the medicinal liquid in the container is discharged from the medicinal liquid outflow pipe 13. , through the tube portion 9 and from the small through holes 10..., which can be ejected upward to wash the eyes. Next, when the above-mentioned compression is released, the container body body 2 elastically returns to its original state, the check valve 14 opens, and the drug solution accumulated in the cylinder body 5 flows into the container body through the drug solution flow holes 8, 8. Therefore, by repeating the compression and release of the container trunk 2, the medicinal solution can be continuously blown up and the eyes can be washed.

"Example" 1 is a container body, and the container body has a mouth and neck part 3 erected from the upper end of a body part 2 which can be elastically compressed.

4 is an eyewash member, and the eyewash member is attached to the mouth and neck part 3.
The lower part of the cylinder 5 is screwed onto the outer surface, and the upper half of the cylinder gradually expands upward and outward, and the upper left and right ends of the cylinder are recessed. The upper end can be easily pressed against the area around the eyes.
Further, a notch 6 is formed at the front of the upper end of the cylindrical body 5 to allow outside air to flow in to prevent the inside of the cylindrical body from becoming a negative pressure during eye washing. An inward flange-like wall 7 is attached to the middle part of the inner surface of the cylinder 5, and a plurality of through holes 8, 8 for liquid drug flow are bored in the inward flange-like wall. Further, on the inner circumferential edge of the inward flange-like wall 7, there is a tube portion 9 whose upper end is closed.
The middle part of the outer surface is joined, and a plurality of small through holes 10 are bored in the upper end surface of the tube part. Further, a lid 11 is removably fitted to the upper end of the cylinder 5, and the lid and the cylinder are connected by a band 12.

The upper end of a chemical solution outflow pipe 13 is fitted into the lower part of the pipe portion 9, and the lower end of the pipe is vertically disposed to the bottom of the container body.

Reference numeral 14 denotes a check valve, and this check valve has a ring-shaped elastic plate 15 held between the upper end surface of the mouth and neck of the container body and the lower surface of the inward flange-like wall 7 as a valve plate. The lower surface of the facing flange-like wall 7 serves as a valve seat, and the medicinal solution in the eyewash member 4 is passed through the medicinal solution flow through holes 8, 8.
It is formed so that it can flow into the container body.

"Effect of the invention" Since the present invention has the above-described structure, the medicinal solution can be continuously spouted upward by repeatedly squeezing the container body 2 and releasing the squeezing, thereby making it easy to wash the eyes. This can be done reliably and quickly. Furthermore, since the container body 1 and the eyewash member 4 are connected, there is no need to forget to carry one or the other, which is extremely convenient.
