BOTTLE GLOSURE AND DISPENSING DEVICE Filed Sept. 11. 1956 Patented Jan. 11, 1938 UNITED STATES PATENT OFFICE BOTTLE oLosUnE Ann DIsPENsING DEVICE Application September 11, 1936, Serial No. 100,273
3 Claims.
a combination bottle closure cap and dropper for alternatively sealing `the bottle and for dispensing the contents of the bottle without removing the closure cap,` the device herein del scribed being especially designed for dispensing oily uids. Fluids other than oily fluids may be dispensed by the closure .cap and dropper herein shown and described, by making the dropper tip and orlice of suitable sizes.
Another object is to provide means, in the combination screw cap and dropper, for forming drops of uniform and predetermined size, for controlling the speed of drop formation, and for preventing the contents from being spilled in the event the bottle is accidentally knockedY over while bsn'ng used.
Another object is to provide means for eili- 1 ciently sealing the bottle when the contents are not being dispensed, and for dispensing the contents without the use of parts (such as rubber bulbs, etc.) which are deleteriously aiected by oily preparations contained in the bottle.
The objects of the invention are attained by the combination cap and dropper herein shown and described, in which the size of the dropper tip has been carefully predetermined. The size of the tip and not the size of the orifice in the tip determines the size of the drops which will be formed by droppers adapted for the purposes herein described. To form drops of 1/40th gram,
thediameter of the tip may range from .1142 to .1418 of an inch, depending on the character of the iiuid being dispensed. The cap-dropper shown,.designed for dispensing an oily uid, has
4o a dropper-tip .117 inch in diameter,'with an orice measuring .067 inch in diameter. vThe size of the orice controls the speed of drop formation Yand may vary slightly, but within certain limits, has little to do with the size of the drops,
for it is on the face of the tip, defined by its periphery, that the drops are formed.
Fig. 1 is an enlarged vertical sectional View of a bottle closure cap with dispensing nozzle and manually-controlled vent, embodying my invention, the same being shown in position on a. bottle, partly broken away, the section being indicated by the line I-I oi Fig. 2. I
. Fig 2 is -a plan view of the device shown in In that embodiment of my invention shown in the drawing, the bottle or other container I0 is provided with a neck II externally screw threaded at I2. The closure cap comprises a thickened top I3 and skirt portion I4, internally 5 screw threaded at I5 for engaging the threads I2. Ihe cap is preferably made of molded material, but may be made of metal or other suitable substance. The thick top I3 is centrally recessed to form an open bottom, cylindrical chaml0 ber I6 in the upper portion of the cap above the upper edge of the neck II of the bottle. The washer I1 ts Within the skirt I4 of the cap and adjacent the lower surface of a shoulder formed in the top I3 outwardly of said chamber I6, A` l5 Washer I 8A of tinfoil preferably protects the Washer I 'I, said washers forming a tight seal between the neck II of the bottle and the cap.
The top I3 of the cap is provided with an air vent, preferably in'the form of a stud I 9, ex- 20 ternally screw threaded, having a vertical vent 20 communicating with the chamber I6 and with the atmosphere when the cap 2I is removed. The cap 2I is screw threaded internally for engagement withthe stud I9, and a gasket 22 provides 25 a tight seal for the vent when thel cap 2| is in place;
At one side of the cap', opposite the chamber I6, is a. boss 23 having a fiat, vertically'disposed annular face'from which projects a screw thread- 30 ed stud 24 terminating in a dropper tip 25 of reduced diameter. A passageway 26 extends from the chamber I6 through the thickened top 4I3 of the cap and through said boss 23, stud 24 anddropper tip 25. The combined length of the 35 st-ud 2 4 and tipv 25 is preferably equal to the length of the air vent stud I9, and the diameters of said screw threaded studs I9 and 24 are also preferably the same, so that identical caps may be used for closing the vent 2l and passageway 49 26.
The cap on the stud 24; is indicated at 21 and preferably it is provided with a pin 28 for keeping clean the passageway 26 through which 45 the contents of the bottle are dispensed. V.A gasket 29 in the cap 2'I makes a tight llt between the dropper tip 25 and the cap.
The diameter of the dropper tip 25, in the present embodiment, is .117 inch, and the di- 50 ameter of the-orifice 26 is .067 inch. 'I'he air vent 2li-in the present embodiment has a diameter of .136 inc h. When dispensing oily products such as sh liver oils this dropper tip Will form' uniform drops 'of 1/40th gram, and at a rate at 55 which they can be counted conveniently and which is not undesirably slow.
The construction described utilizes a vacuum principle to adjust the head pressure on the body of the uid so that the pressure remains constant regardless of the size of the bottle or the amount of liquid in the bottle.
The combination cap and dropper, properly screwed to the bottle ill, is leak-proof when 4the caps 2| and 21 are in place and the contents will .not spill when the openings 20 and 26 are uncapped. I'he liquid will not spill out of the vent 20 because the vacuum in the bottle is not re'- leased fast enough by the small orifice. 26, and will not spill out of the dropper orifice 26 because of the resistance provided by the walls of this small passage.
Changes may be made in details of construction without departing from the scope of my invention and I do not intend to be limited to the exact form shown and described, except as set forth in the appended' claims.
I claim:-
1. A dropper for a container comprising a container cap, a lstud adjacent to one side of the cap extending from the upper end thereof and having a small op'en vent orice therethrough which is above the liquid surface in the container and cap while in dispensing position, a stud extending laterally from the other side of the cap, a tip having a specied plane area extending from said stud so as to form drops of material inthe container of a specified size when it is extended downwardly so as to be below the liquid level in a dispensing position, and said stud and tip having an orice therethrough of a size to permit a restricted ow of uid therethrough to control the rapidity of the drops.
2. A dropper for a container in accordance with claim 1 in which the studs on the end and side of the container cap are provided with removable closure sealing caps.
3. A dropper for a container in accordance with claim 1, wherein the tip area is .117 inch in diameter and the orice is 067 inch in diameter so as to produce drops of 1/40th gram for an oily
