An object of my invention is to provide a new, novel and improved tap for a sealed container having a vent that is automatically opened and closed as the tap is respectively opened and closed.

Another object of my invention is to provide upon a tap for a metallic container means whereby the tap may be readily mounted in a wall of the container at any desired point.

Another object oi my invention is to provide a new and novel type of metal cutting and screw The threaded threaded attaching means for taps such as are considerably more used for dispensing fluids from metallic conthreading and the bayonet I5 tainers. outer surface disposed in substantial ing'beyond the ange II, threaded extension shaped bayonet along both edges and form a round hole in a therein.

In the drawing wherein like numerals refer to like 'parts throughout the several views:

Figure l is a perspective view of the tap,

Figure 2 is a sectional view taken along a vertical plane extending through the center of the tap,

Figures 3 and 4 are perspective'views showing the .valve element in two-positions,

Figures 5 and 6 are sectional views taken along V--V of Figure 2 showing the valve member respectively in its closed and open positions,

Figure '7 shows my improved tap appliedto the end of a metallic container,

Figure 8 is a fragmentary sectional view show-` ing the tap applied to of al barrel,

Figure 9 is a fragmentary view partially insection showing the manner of mounting the tap upon a container having a conventional screw cap closure, and

Figure l0 shows an adaptation of tap to the neck of a bottle.

As illustrated in the accompanying drawing, the preferred form of my invention comprises a to draw the bayonet I5 inwardly so into the container and hold the abutting remaining portion of the threaded extension Il into close engagement with the-wall oi the container and, because of the disposition of the threads, insures a progressive entrance of of the tap body into the wall of the container, as the tap body is turned to move the bayonet in a circle. The end oi' the threaded extension I4, from which the bayonet I5 extends, is disposed at a right angle to the axis of the bayonet and forms a shoulder I4' at each side of the bayonet which will engage the wall of the container, when the bayonet has been projected therethrough, and hold' the bayonet perpendicular to the container wall and thus cause it to travel in a circlecorresponding to the curvature oi the bayonet. This type of bayonet and threaded extension will cause the metal wall of the container to be rolled back as a hole is out therein and provide metal upon which threads will be formed by the extension I4.

In the top of the valve body spout I3, there is a pose of permitting the entrance of air my improved the threadedA portion 35 sealed container when the tap is applied as will hereinafter appear.

Cooperating with the spout I3 there is provided a hollow cylindrical thereto,

At the inner prevents the escape of uid around the 'outside of the valve member I1. As illustrated in this through the spout I3. The eccentric groove 25 is extended around one half of the valve member I1 working through the spout vent and milling a valve 26 is disposed.
