Description In the spec-ificembodiment of the invention illustrated in said drawing, the tap is shown in Figs. 2 and 3 in association with one type of container I0, illustrative of a conventional can or the like made vof sheet metal and usually sealed with a substantially dat top or cover il, Whereas Fig. 4 is illustrative of a conventional bottle IIIA having a crown seal cap or cover iIA of sheet metah In either or both cases, the contents of the container may be under pressure, although not necessarily so. The invention has particular merit in use with containers where hereinafter.

(Cl. 22d-.23)

the contents are under pressure in that the tap, as Will be herein subsequently made more evident, is applicable to such containers Without depreciating that pressure. In any event, the contents are of a fluid character andthe tap is constructed to permit pouring thereof Whether the fluid be under pressure or not.

The tap comprises essentially a body portion I2 from the bottom of which protrudes a punching and retaining' element I3 surrounded by a flexible protector designated in'Figs. 1,1 2, and 3 by reference numeral Iii and designated in Figure 4.by a reference numeral I 4A. The details of construction of these several primary elements of the tap may be considerately varied, `and the drawings merely show one embodiment of the invention and are to be considered illustrative thereof rather than restrictive except as claimed For convenience in manufacture, the body portion I2 and element I3 are shown as made separately and assembled by screwing the element I3 into a threaded socket provided for that purposev in the bottom of body portion I2, After the assembly is accomplished, the body portion I2 and element i3 are never separated in use, and for all practical purposes may be considered an integral assembly. The particular structure shown utilizing a body portion I2 and element I3 of separate parts is especially adapted tomanufacture ofthe body portion of such materials as molded Bakelite and yet enabling the punch to be of metal. The body portion may,y however, be of any suitable material of Which metal is another example, and in which event the body portion and punch element may be of the same metal and integrally formed. vThe bod-y portion is made with a vertical channel I5 therein and a transverse channel I6, said channels intersecting and the transverse channel having a discharge opening through a snout I'l at one side of the body portion. At the opposite side of the body portion is provided a threaded neck I3 for receiving a stuing box I9 through which protrudes a threaded shank 2li of a valve stem at the outer end of which is knurled finger piece 2| and on the inner end of which is a tapered needle valve 22 adapted to engage and seal with respect to a tapered seat 23 formed in transverse channel Iii. Threaded shank 2B has a threaded engagement With the Walls oi the transverse channel I5 so that the valve may be manipulated back and forth into and out of engagement with-seat 23 as found desirable in use. When the "valve is retracted, flow of liquid will be permitted from vertical passage I5 to transverse passage I6, thus permitting escape of fluid from snout Il' of the body portion and when is no longer desired valve stem 20 is screwed in again so that tapered needle valve 22 seats against tapered seat 23 and completely seals the discharge against exit of the fluid.

The punching and retaining element I3 is shown as having its end next the body portion screw threaded for introduction and retention of that element within the body portion, and is shown with its lower end tapered and terminating in a relatively sharp point 24 suciently to permit the element to be forced through a lid or other thin metallic wall II or IIA. This lower tapered end of the element I3 is likewise preferably screw threaded, the threading being shown as having a considerable taper on the lower side or surface 25 of the convolutions and having a shouldered upper side 26 which is normal or more nearly normal to the central axis of the element than the surface 25. It will accordingly be seen that the element after being punched into a cover may be screwed further into the stem, spreading the material of the cover at the puncture and obtaining both a threaded and retaining engagement therewith preventing leakage and preventing an inadvertent withdrawal of the element from the puncture. As close as practical to the pointed end 24 of the element is provided a transverse inlet or aperture 21, and the element is provided with a central channel or bore 28 from its upper end as far as said inlet 21, thereby admitting fluid from the container up through element I3 to the channel I5 of the body portion almost immediately upon puncturing the container. It is through this aperture 21 and channels 28, I5 and I6 that the container contents are permitted to escape as desired by virtue of the pressure of the container contents accompanied by appropriate tilting and pouring of the container and attached tap.

The body portion preferably has mounted thereon a flexible protector I4 or I4A, depending upon the type of container to which the tap is being applied. This protector is preferably of rubber or some similar material enabling it to distort, stretch, iiex and be removed and replaced by the operator as desired. As here shown, the body portion has an annular groove 29 in its outer surface near the bottom, this groove receiving a flange 30 projecting radially inward at the top of the protector. The protector preferably has a depending skirt portion 3| (Figures 2 and 3) or 3IA (Figure 4), for engagement with the container as tap is being applied thereto. As shown, the skirt portion 3l preferably is extended downward to a plane below the pointed end 24 of the punch element. The tap may therefore be rested upon a plane surface without engagement of the point 24 against that surface,

and when it is desired to use the tap it will effect.

a seal with respect to the container top or surface before the punch becomes effective to puncture the container top. The exibility and elasticity of the protector permits the punch to be depressed at the same time stretching the protector into more intimate contact with the container and thus obtaining even better sealing as the puncturing proceeds. In Figure 3, it will be observed that skirt 3| spreads laterally, and in doing so the ange 30 will be pressed with greater force into the groove 29. However, when the tap is not pressed down, as in its position of Figures 1 and 2, the protector is relatively loose with respect to the body portion I2, and may be snapped on and oif the body portion as above indicated. In Figure 4 the protector normally depends when off the bottle in substantially the position shown upon the bottle, the elasticity of the protector enabling the lower bead thereof to pass over the crown seal cap and peripheral bulge 32 of the bottle and to seal against the neck of the bottle and immediately below the bulge mentioned. This protector likewise may be snapped on or off the body portion I2 when not upon a container, and thus the user requires only one of the body portion and a selection of protectors for using the device on different types of containers. It is particularly noted that crown cap II is retained upon the bottle and does not have to be removed in order to apply the tap of the present invention. I am accordingly enabled to retain the pressure of the contents of the bottle while applying my improved tap thereto, and do not relieve the pressure until ready to pour the contents through the tap It is furthermore to be noted that in use, whether with flat top engaging protector I4 or the bottle neck engaging protector I4A, the body portion may be rotated with respect to the protector, enabling the protector to tightly engage the container while the tap is being screwed into the puncture made in the container lid. Furthermore, the tap is made with a projecting snout I'I at one side and neck I8 and valve stem 20 at the other side thus giving an ample leverage for the operator to grasp and rotate the body portion for screwing the tap into a container, and said body portion furthermore provides a flat top enabling the operator to apply necessary pressure for obtaining initial puncturing of the container top.

It is to be understood that while I have specically described the puncturing and retaining element as provided with a lower point 24 above the plane of the lower edge of the protector, it is within the scope of the invention to vary the position of this point to project to or beyond the plane of the lower edge of the protector, if so desired. With regards to the particular protector shown in Fig. 4, the projection of the protector considerably beyond the point 24 is especially desirable in order that the protector may serve to center the punching element with respect to the crown sealed cap- I IA. I furthermore wish to point out that in connection with both types of protectors, a space is left between the top of the container and the under wall of the protector around the punch. This space, by virtue of the exibility and resiliency of the protector II, will tend to create a vacuum and thereby hold the tap more securely in place upon the container.

It has been found advantageous to utilize a slightly modified form of tap in the construction of the body portion I2 of Figure 6. In this connection it may be said that the construction is similar throughout with the exception of the shank 20 and the body portion which receives the shank for actuating the valve 22 for permitting ow of liquid and closing the valve. Instead of using a threaded shank as heretofore, and to assure positive closing of the valve when a desired amount of liquid has been removed from a container, it is preferable that the shank have its stem without threads. The body portion at the part enclosing the stem of the shank and extending inward from the farthest end of the valve is provided with a bore hole 33. Within said bore hole and enclosing the stern of shank 20 is a non-corrosive coil spring 34, and held in place by the stuffing box I9. The end of said spring nearest the valve 22 is held fast to the stem of the shank within a hole 35 therein. In operation it Will be readily observed that by pulling the shank in an outwardly direction clutching the finger piece 2| the Valve will be opened and liquid permitted to flow out through passage i6. Immediately upon releasing the hold on the finger piece 2| the shank thereupon will be forced inwardly and the valve return to its closing position by virtue of the pressure eX- erted by the spring 34 and its secured end to the stem of the shank.

I claim: I

A receptacle tap comprising in combination a body portion having a threaded tapering punch protruding therefrom, and a hollow protector carried` by the body portion and flaring around the punching element, said punching element and protector being substantially axially concentric,

said punch having a point at its lower end positioned above a plane of the lower edge of the protector.
