April 10, 1945. A. BERG DISPENSING TAP Filed June 25, 1941 INVENT OR. w/wm r 55 BY 7 64 E A Patented Apr. 10, 1945 UNITED STATES DISPENSING TAP Anthony Berg, Milwaukee, Wis.
Application June 23, 1941, Serial No. 399,373
means of sealing beer or other beverages in tin cans arranged in a manner to permit access to the contents of the can without causing a waste of the contents.
Another object of my invention is to so construct the container as to allow for expansion and contraction due to a pressure variation caused by a change in atmospheric temperature.
A still further object of my invention is to provide a. sealing means that will not protrude above the surface of the container, yet permit sealed engagement with the dispensing means prior to the piercing of the seal in the container.
Still another object of my invention is to so constructthe dispensing means as to permit its use on any number of containers by removing it from the container after its contents have been drained.
Other and further objects of my invention will become more apparent as the description proceeds when taken in conjunction with the draw- I ing in which Figure 1 is a fragmentary perspective view of the dispensing tap attached to the seal of a container arranged for that purpose,
Figure 2 is a fragmentary cross-sectional view of the device attached to a container and ready for piercing,
Figure 3 is a fragmentary cross-sectional View of the piercing tap ready for penetrating the sealed can,
Figure 4 is a fragmentary cross-sectional view of the piercing tap penetrated throughthe sealed can, and
Figure 5 is a cross-sectional view of a portion of the can showing the sealing means and its relation to the upper bead of the can.
Similar characters of reference indicate corresponding parts throughout the several views, and referring now to the same, the character Ill shows a spigot or faucet having a threaded portion ll acting as a hollow shank for the faucet Ill. The threaded shank H is shown as having a conical piercing point l2 provided with apertures l3. Above the threaded portion of the shank H is shown projecting thumb members l4 and M and.
a flange member I 5 provided with a recess in which is embedded the washer l6 as shown.
' A sealing cap I! threaded as shown is arranged to engage the projecting portion l8 of a-can I9.
This projecting portion l8 of the can I9 is provided with a seal 20, The cap I! is provided, with a shoulder 2| around its periphery and this shoulder is adapted to receive a washer 22 to engage the rim of the projecting portion [8 of the can I9. The cap 11 is further provided with a threaded aperture 23 provided with an upwardly projecting flange 24 shown brought to a sharp edge 25 to engage the washer IS in the flange l5, when the shank I l is revolved by means of manual pressure exerted on the thumb members 14 and M.
In this manner as the shank II is revolved by means of the members l4 and I4 the point I2 is brought in contact with the seal 20 and as it pierces the seal 20 the edge 25 contacts the washer i6 and the liquid contents of the can I9 is permitted to reach the faucet I0 through the apertures 53. The washer 22 will cause the device to be sealed while the piercing operation takes place and will prevent any loss of the contents during the tapping of the can.
Inasmuch as a device of the character described would probably be employed for dispensing beer or carbonated beverages the can l9 acting as a container for such beverages would-have to be designed to take care of expansion and contraction caused by atmospheric changes and the beads 26 in the wall of the can whether they be vertical or horizontal are quite imperative.
Also to enable the can l9 provided with a pro-' jecting portion Is to attach the tapping device to, to be stacked'one on top of the other without interference, the upper bead 21 of the can I9 will have to be raised to a height greater than the height of the projecting portion l8 as shown in Figure 5.
It is manifest to anyone familiar with the art that non-returnable tin cans are more economical for the transportation and marketing of beer or the like than glass bottles and wood Or metal kegs. It is also quite obvious that a gallon can for example can be produced and filled much more economically than the capacity equivalent in small cans.
The can and tapping device as described provide a means of satisfactorily taking advantage of the economical features outlined, the can may be discarded and the tapping device used over and over.
Although I have shown and described a particular construction of my device, it is t be understood that I can make such changes as I may deem necessary without departing from the spirit of my invention as set forth in the appended claim.
What I claim and desire to secure by Letters Patent of the United States is:
A device of the character described for use with a container having a sealed projecting portion,
extending outward from said container, said projecting portion being threaded on its outer periphery, a faucet, said faucet provided with a threaded hollow shank, said shank provided with a conical piercing point at its end, a sealing means, said sealing means having an internal 10
