RUTH W. BREEDING, OF PHILADELPHIA, PENNSYLVANIA, NOW BY JUDICIAL ORDER RUTH G. WILLIAMS EYE DROPPE-R Application filed February 11, 1928. Serial No. 253,551.

The present invention relates to eye droppers and has more especial relation to an eye dropper of novel structure heretofore unobtainable upon the open market.

The leading or principal object of the present invention may be said to reside in the provision of a novel form of paper or similar tube arranged for separable connection with respect to a rubber bulb in order that the paper tube may be detached from a rubber bulb, after a single use, and thrown away.

A further object of the present invention is to provide a paper or similar tube which is tapered and spirally wound and treated with paraffin or like substance.

IVith these and other objects in view, the invention consists of the novel construction hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which Fig. 1, is a View in perspective of an eye dropper embodying the invention, shown in position for use in connection with a medicine bottle.

Fig. 2, is a view in perspective of a paper stopper part detached from a rubber bulb; and

F ig. 3, is a view in perspective of a slightly modified form of construction in which the eye dropper is used as a bottle stopper, the bottle being shown in dotted lines.

For the purpose of illustrating my invention, I have shown in the accompanying drawings two forms thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various inst'rumentmlities of which my invention consists can be variously arranged and organized, and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

Referring to the drawings in detail, the eye dropper is made of paper and is spirally wound as at 1, and terminates in a cylindrical portion 2. In the winding of the spiral portion 1 of the dropper, paraflin, Wax, or similar material is used to cause the spirally wound parts to adhere. These parts 1 and 2, as before stated, are of paper and are adapted for but a single use so that they may be thrown away or discarded, thereby avoiding infection to the person using the same after a previous use. The reference numeral 3 designates a conventional rubber bulb which is fitted to the cylindrical part 2 of the dropper in much the same fashion that a glass dropper would be fitted to a rubber bulb. The principal function of the present device is to provide a simple, inexpensive, and efficient mem ber, made of paper, spirally wound, and paralhned or waxed to provide an integral structure which may be fitted to a conventional rubber bulb 3. This structure is clearly illustrated in Figs. 1 and 2. In Fig. 1 the reference numeral 4 designates a bottle adapted to contain, for instance, medicine for the eye, and Fig. 1 clearly illustrates how the eye dropper may be used.

Referring now to Fig. 3, a bottle designated by the reference numeral 5 is shown to which is applied a combined bulb 6 and stopper 7. By this arrangement, the bulb 6 and stopper 7 combine to efliciently close the mouth of the bottle 5. Detachably connected with respect to the bulb 6, as for instance as is shown in Fig. 1, is the spirally wound, paraffined paper tube 1.

It is thus apparent that the paraflined and spirally wound tube 1 may be either attached to a rubber bulb 3, shown in Fig. 1, for ordinary use, or may be attached to a rubber bulb 6 having a bottle stopper member 7. In either event the spirally wound member 2 can be detached from the rubber bulb after a single use, and discarded because of its small cost, thereby avoiding possible infection to the user.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

What I claim is:

1. An article of the character stated comprising a spirally Wound, fibrous member, the meeting, overlapping edges of which are adhesively secured, the spiral, tapered parts terminating in a generally elongated cylindrical portion, and a rubber bulb attached to said member, the structure throughout being of circular'cross section.

2. In combination a bottle including its neck, a spirally Wound, fibrous member, the meeting, overlapping edges of Which are adhesively secured, the tapered parts terminating in a generally elongated cylindrical portion, the structure throughout being of circular cross section, saidcylindrical portion being arranged for insertion Within a rubber bulb, a rubber bulb detachable With respect to said member, said bulb having a part for closing the neck of said bottle. 7
