DISPENSER Filed Nov. 28, 1940 1 Patented Mar. 31, 1942 DISPENSER James S. Rosenblatt, Chicago, 111., assignor to Origination, Incorporated, Chicago, Ill., a corporation of Illinois Application November 28, 1940, Serial No. 367,589
Claims.
This invention relates to an improvement in the art of liquid dispensing, and particularlyto dispensing devices, easily constructed, which dispense liquids in drops or in a predetermined quantity from a container or bottle.
Heretofore, a considerable number of bottle or containers have been sold on the market for liquids that shouldbe dispensed in pre-determined quantities. Unless one is skilled in the art of dispensing liquids, it is highly impracticable to control the flow so that the liquid can be dispensed one drop at a time and can be measured in drops or dispensed in a limited predetermined quantity. For the purpose of convenience, reference hereinafter made to a "bottle is meant to also include container.
I have invented a device, which, without moving parts, will dispense liquids a drop at a time or in a limited predetermined quantity when the container is inverted. By the application of a properly proportioned siphon or tube I am enabled to regulate the pre-determined flow of liquid (i. e., one drop, two drops, three drops, four drops, etc). This device may be easily and economically made as an integral part of a bottle or can be made as an appliance or attachment to the bottle by provision on the neck .of the bottle by means of snap fastenings, friction joints, threads, and may .be wedged into the bottle or permanently attached by means of soldering, welding, amalgamation, molding such as in plastics, etc.
The invention will be described in detail in connection with the accompanying drawing which illustrates diagrammatically a dispensing device, which exemplifies but does not limit the invention.
Fig. 1 is a sectional view of one form of a dispensing device, being shown in an upright position, embodying my invention; 1
Fig. 2 is a sectional view of the dispensing device in an inverted position showing the liquid being dispensed;
Fig. 3 is a sectional view of another form of dispensingdevice embodying my invention; and
the neck l2. The opening Ii at the outer end It is smaller in diameter than the bore ii, to restrain the flow of liquid and air and to regulate the size of the drops dispensed. The neck [2 of the bottle around the tube l3 must be solid so that there is no leakage of air pressure through the neck I! of the bottle which is around the tube or siphon l3,
Fig. 2 shows an inverted bottle showingthe liquid being dispensed when bottle I0 is inverted. The principle or theory upon which the dispensing takes place is due to kinetic energy of the liquid l9 when the bottle is inverted for dispensing, causing a momentary unbalance of pressure between atmospheric pressure at the outer opening l6 and the internal pressure on the opening at H, thus creatinga greater fluid pressure force at opening H. The air pressure from entering. The liquid flows in drops, one
drop at atime .(see 2-3) As the liquid flows from the tube-l3 andjopenin'g IS an air bubble 22 passes through 'opening Ii' into and through tube l3 into bottle l0 displacing-the dispensed. When the kinetic energy is spenfl the force at opening I will equal the force at opening 11. The condition is. then static and liquid can not flow from the bottle until there is a repeated momentary unbalance such as caused by again inverting the bottle. I
In Fig. 3 of the drawing there is shown a modifled iorm of dispensing device embodying the principles of this invention. In this form the bottle I0 is provided with a dispensing devicell attached thereto or made an integral part thereof. The device It has extending therethrough a tube l3, which in this dorm of the invention extends a considerable distance into the bottle. The tube I3 is provided with a fluid inlet port It in its side wall just below the neck. I: at the bottle. It is through this port II that liquid enters the tube I3 to be dispensed when the bottle is inverted.
tube between its end l4 and the fluid inlet port It is filled with air, it being understood that the 'how far the tube or siphon protrudes above liquid level will be below the inlet I8. Upon inverting the container, the liquid will enter the tube through the port [8 while the air trapped It will, therefore, be seen that by varying the. position of the port IS with respect to the discharge en d of the tube, which results in varying the length of the air column between port l8 and the discharge end of the tube [3, the quantity of the liquid dispensed can be controlled and predetermined.
The size or character of the flow dispensed will depend upon the size of th opening 16 at the outer discharge end of the tube. When this opening I6 is restricted, theflow will be in drops depending upon the degree of restriction.
In the. construction of my device, I wish to emphasize that no adjustments nor moving parts are required for the proper functioning of the device. The usual methods employed in dispensing are entirely done away with. It is neither necessary to shake the container, employ additional appliances, nor numerous cap fittings. In order to operate the device, all that is necessary is to invert the container once and a predetermined quantity of liquid will be dispensed, the flow ceasing when a static condition is established.
I claim:
l. A dispensing device of the character described, comprising a receptacle for fluid to be dispensed, a single tube fitted in operating relationship with and extending through an opening in said receptacle to a point within said receptacle at a substantial distance below said opening, said tube having restricted outer and inner end openings, said tube being of such a length and so proportioned as to permit a predetermined number of drops of the contained fluid to be dispensedupon inverting the receptacle, when said outer end opening is exposed to the air. I
