LIQUID POUR-ING- v Filed June 21, 1940 V Z47 I I Z52 [Am/37m Patented Feb. 23, 1943 UNITED STATES PATENT OFFICE LIQUID POURING Lee C. Lanfare, Toledo, Ohio Application June 21, 1940, Serial No. 341,765
This invention relates to handling of liquids from, to or between vessels, one or more of which may be closed for releasing air or gas balance, in thereby promoting flow continuity.
This invention has utility when incorporated in integral self-filling or unitary plastic fixtures for insertion in neck openings of bottles, with provision of a pouring stopper, and has to do more particularly with a dispensing of beverages or liquors.
Referring to the drawing:
Fig. 1 is a side elevation, with parts broken away, of an embodiment of the invention as in assembly at the neck opening of a liquor bottle;
Fig. 2 is a view of the device of Fig. l tilted to pouring position;
Fig. 3 is a plan View of the device of Fig. 1, looking down on the unit;
Fig. 4 is a section on the line IV-IV, Fig. 3, showing the ducts or pouring passage as well as the vent passage in association with a stopper or cork; and
Fig. 5 is a section on the line VV, Fig. 4, showing the seating of the tube for a cork sleeve of the stopper type.
The bottle neck mounting Liquor bottle I is shown having neck 2 with opening 3 therein. In the instances wherein the pouring type of stopper is desired, there may be inserted in this opening 3 a tapered compressible section 4 having central opening 5 therethrough as a seating place for the pouring device.
The plastic fixture unit Into this central tubular opening 5 of the stopper or cork 4 may be thrust cylindrical portion 6 for the outer terminus of this stopper 4 to abut shoulder I and leave therebeyond an inner recess or chamber 8, communication to which is had from interior tapered terminus 9 on the tubular portion 6 by way of slot III having open outer side II toward the inner side of the chamber 5 of the cork and being closed on its inner side by rib I2 along the inside of way I3 from the taper or slant portion 9. This rib I2 has terminus I4 on the inside of this duct in the region of intermediate enlargement or cap portion I5 about the chamber 8, and from which toward and about the tube 6 there extends skirt or flange I6 having clearance I'I about the compressible stopper or cork 4. This clearance II has communication by notch I8 directly with the chamber 8 and thence to the vent duct III entirely independent of the passage I3 which, as beyond the enlargement I5, has spout portion I9 to delivery port 20.
Method of placement The compressible element 4 having internal cylindrical opening 5 may have such thrust into position along the tubular portion 6 of the plastic unit for this stopper element to abut the shoulder 1. The unit as thus assembled may be inserted in working position with the bottle, say of liquor, by jamming the stopper 4 into the opening 3. In practice, this may leave slight clearance 2| between the free end of the skirt I6 and the top or neck of the bottle 2.
In normal position the vessel or bottle I or the like is in upright position. As there may be cccasion to dispense, the tendency of the one mixing the drinks or serving is to upend or tilt the vessel I rather quickly, thereby causing the liquid to lunge with an impinging action against the inner end of the stopper 4 of the closure with a flow in major volume through the duct or tubular portion I3 and way I9 for discharge by the port 20. This impinging flow is for a much less quantity into the vent duct Ill. As such strikes wall 22 of the chamber 8, flow is retarded, and as the pouring angle is retained, the liquid from this vent I0 is in the chamber 8 normally clear of its entrance by the vent III for the vent III to function by way of the adjacent notch I8 and clearance II, thereby allowing air balance say by inflow into the vessel I. This means there is a continuity in stream 23 at the initial tilting or pouring.
In practice, in the event the one should effect impinging operations, two or three in number, the capacity of the chamber 8 is effective therefor. At once the vessel is righted, this chamber 8 drains back into the container as to the liquid charge therein. There is accordingly avoidance of any contamination. There is less exposure of the contents than at the port 26. In having the composition say of plastic as of the urea or cellulosic type, there is burnish or high polish finish not reacting to beverage or weathering exposure.
What is claimed and. it is desired to secure by United States Letters Patent is:
A plastic unit closure embodying a tubular section, a spout section, and an intermediate cap portion therebetween including a skirt toward and about the tubular section away from the spout section, said skirt having therein a ledge adapted to limit the extent of stopper entrance thereinto, there being further communication provision from such ledge outward inside the skirt, and inward along the tubular section away from the spout, to the end that there is provided a vent with an intermediate chamber adjacent the ledge.
