naorrna DEVICE.
Specification of Letters 2atent.
application filed April 24, 1914. Serial H0. 834,072.
To all whom it may concern Be it known that I, JOSEPH NEGER, a citizenof the United States, and a resident of the city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Dropper Devices, of which the following is a specification.
My invention relates to a liquid dropping device for the purpose of permitting the contents of a bottle or other vessel to flow out in the form of drops, enabling the user to count them so that any given number of drops of the contents may be had. I have found that by the use of two passages oppositely tapered, one as an air-inlet, and the other as an outlet for the contents of the bottle, that the tendency of the liquid to flow, which is one of the objections to most droppers of the art, is overcome.
In the drawings in which like letters relate to like parts, Figure 1 shows a bottle with a portion broken away to show my invention in its preferred form; Fig. 2 shows the cork; Fig. 3 shows the dropping device which is placed in the cork; and Fig. .4 is a view of Fig. 3 in the direction of the arrows.
A is a bottle which may be of any form.
B is a cork adapted to be placed in the neck of the bottle.
G (Fig. 2) is a passage-way in the cork which is preferably tapered.
C, which may be made of glass or any suitable material, but which I have shown made of glass, is my improved dropping device, which consists of two oppositely tapered passages D and E, having at their smaller ends outlets D and E, which are curved in opposite directions, as shown in Figs. 1 and 3.
The tapered passage-D is preferably the liquid outlet passage, and the tapered passage E, the air-inlet passage. While I have shown the passage D a trifle larger in diameter at corresponding points than the passage E, this is not essential, as the two passages may be of similar diameter at similar points, but I prefer that the greatest diameter of the air inlet passage E shall be at the point where the air enters the passage, and the greatest diameter of the outlet passage D shall be at the point where the liquid enters the outlet passage.
In the preferred form of my dropper device, the circumference is greater at the lower end, as shown in Fig. 3, than at the upper end, shown in that figure, so that as the device is placed up in the cork B, it may be pushed forward forming a tight joint.- After the dropper device (Fig; 3) is placed n the cork (Fig. 2), and the liquid placed in the bottle, the cork is then inserted in the bottle, as shown in Fig. 1, and is ready for use.
In using the device the bottle is tipped so that the outlet D is held below the inlet to the air passage E, as shown, when the drawmg is held so that the bottle is in a horizontal position, with Fig. 2 under the bottle. In this position the liquid will flow into the outlet passage D, air will enter the inlet passage E, and the liquid will pass out of the outlet passage D drop by drop, as air enters through the passage E and out through the air-outlet E into the bottle. In the preferred form of my invention, the air outlet E is turned so that the outlet is substantially parallel to the neck of the bottle. It will be seen that the cork being compressed by the neck of the bottle forms a tight joint around the dropping device so that no air can enter except through the pas-- sages in the dropper device.
When desired for sanitary purposes, and also for the purpose of preserving the contents of the bottle, I provide a cap F, formed of glass or similar suitable material, adapted to fit over the top of the cork, and form a tight joint therewith so that no air may enter the bottle, or dirt come in contact with the dropper device or passages in the dropper device. This cap I preferably form so that the innersurface at its lower point is slightly curved or beveled (as shown at I) to enable it to be readily placed over the cork, then as it is pushed down on the cork, it compresses the cork and forms a tight joint therewith. I also provide the flange or shoulder H adapted to engage with the flange or shoulder on the bottle or vessel.
Modifications and changes may be made without departing from the spirit of my invention.
What I claim as new and desire to secure by Letters Patent is 1. The combination of a dropper device consisting of a discharge passage and an air inlet passage, said passages being oppositely tapered, the inlet passage having less taper Patented July 2?, 1915.. j
than the discharge passage whereby the device tapers toward the outlet end of the dis charge passage, the outlet openings of said passages beingof a size that while retarding the discharge of the contents of a receptacle, said contents will be discharged in drops, and a receptacle stopper having an out- Wardly tapering hole through which the 'dropper device extends.
2. The combination of a dropper device consisting of a discharge passage and an air inlet passage, said passages being oppositely tapered, one of said passages having less taper than the other passage whereby the device tapers toward one of its ends, the outlet ends of the passages being curved away from the center line of the device in opposite directions, and a receptacle stopper having a tapering hole through which the dropper device extends.
3. The combination of a dropper device consisting of a discharge passage and an air inlet passage, said passages being oppositely tapered, one of said passages having less taper than the other passage whereby the device tapers toward one of its ends, and
a receptacle stopper having a tapering hole. through which the dropper device extends.
In testimony whereof, I have signed my name to this specification, in the presence of. two subscribing witnesses,
JOSEPH NEGER. Witnesses:
