My invention relates to an improved eyewash bottle In treating the eye with liquids in the case of injuries or irritation it is customary 5 to employ an eye-cup, a small receptacle by dissolving boric acid in Water at an elevated temperature and separating precipitated boric acid after cooling the solution to ordinary temperature.
Usually, such solutions are kept in stoppered bottles from which portions are withdrawn for use in an eye-cup as necessary,
but unless both the bottle of solution and the eye-cup are together, the treatment cannot be quickly or conveniently carried out.
With a separate eye-cup and solution bottle, the two can beeasily separated so that they are not immediately available in the case of accident, and this is particularly true in establishments where intensive industrial operations are being carried out. My invention provides an improved combined eye-cup and eye-wash bottle of construction such that the eye-cup and the solution cannot be separated while at the same time the solution is kept in a closed container until ready for use. My invention also provides for protection of the eye-cup until it is to be used, and has several other important advantages as will appear from the following detailed description. 7
The accompanying drawings illustrate an embodiment of my invention from which.
the characteristic features and advantages of my invention will be apparent. In the drawings, Fig. 1 is a'vertical sectional view of an'eye-wash bottle embodying the invention, and Fig.2 is a section on line 22 of Fig. V
Referring to the drawings, my improved combined eye-cup and eye-wash bottle is made up of a bottle portion 3 adapted to contain a portion of the eye-wash and an eye-cup portion 4 formed integrally with the bottle portion and joined thereto through the neck portion 5. The eye-cup portion is provided with a rim of contour adapted to fit about an eye. Between the interior of the eye-cup portion and the interior of the bottle municating passage 6. A stopper @IS arranged to close this passage and to retain liquid in the bottle portion. ,Thisstopper may with advantage be provided with a depending rim 8 arranged to cover the rim of'the eye-cup and to protect the eyecup portion from contaminating influences when the stopper is in place in the bOtlllQr The portion, there is a comcombined eye-cup and bottle and thestop per may be made of glass.
For use in industrial establishments, a number of bottles of the construction illus trated in the drawings are provided at convenientlocations and are kept filled with appropriate solutions for treating the eye in connection with the work involved. The solution is retained in the bottle portion where it is protected by the close fitting stopper until it is to be used. Where the stopper is provided with a depending'rini as illustrated, the eye-cup portion also is protected until it is to be used. In case of accident, the stopper is removed and after placing the eye-cup against the eye the bottle is inverted by tilting back the head so that the eye-wash solution runs from the bottle portion into the eye-cup portion and,
is there brought into contact with the eye. After use,
the eye-wash bottle may be sterilized, refilled and restoppered for use when p next it becomes necessary.
It will, be apparent that, with an eye wash bottle of the construction provided by my invention, the eye-wash solution and the eye-cup are necessarily together when necessity for their use arises and that the only operation involved in making theeye-wash solution available for treating the eye is the removal of the stopper.
By making the bottle ofrigid construction, accidental dis placement of the solution 1s made impossible. To avoid accidental infection, the
bottle portion is made of a size just sutlicient to hold a portion of the eye-wash solution for a single treatment so'that the bottle must be refilled every time it is used.
My invention'thus provides an improved eye-wash bottle of construction such that the supply of eye-wash. solution and the means for treating the eye with the solution are necessarily kept together, inwhich the chance of infection such as is encountered in theuse of a common eye-cup may be eliminated, and in which the eye-cup as 5 portion eye-Wash, said bottle portion having formed V j wel l as the-eye-Wash solution may be protectecl from oontaminating influences.
