Eye dropper

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.

j 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 io 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 15 with paraffin or like substance.

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

The nature, characteristic features and £0 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

Fig. 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 ⁴⁰ reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized, and that my invention is not limited to the precise arrangement 45 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 33 portion 2. In the winding of the spiral por tion 1 of the dropper, paraffin, 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 55 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 60 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 member, made of paper, spirally wound, and par- 65 affined 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 70 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 75 to which is applied a combined bulb 6 and stopper 7. By this arrangement, the bulb 6 and stopper 7 combine to efficiently close the mouth of the bottle 5. Detachably connected with respect to the bulb 6, as for instance as 80 is shown in Fig. 1, is the spirally wound, paraffined paper tube 1.

It is thus apparent that the paraffined and spirally wound tube 1 may be either attached to a rubber bulb 3, shown in Fig. 1, for ordi- ⁸⁵nary 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 ⁸⁰small cost, thereby avoiding possible infection to the user.

I am aware that the invention may be embodied in other specific forms without de- ₈₅parting 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 100
