The object of my invention is to produce a tapping device for removing liquids from sealed tin containers without removing a wall section therefrom.

Another object is to provide a can tapper for thin metal liquid containers, provided with a sealing unit therein.

A further object is to produce a detachable tapper suitable for table use on small cans, especially designed for converting the can into a dispensing pitcher.

A still further object is to provide a can tapper and sealer, simple in construction, quickly attached to any can, easily and efiiciently operated and that can be manufactured at a very low cost.

These several objects are attained in the preferred form by the construction and arrangement of parts more fully hereinafter set forth.

Similar parts on all drawings are marked by similar numerals or letters.

It is common knowledge that various liquids are materially aifected when exposed to air for a continued time, either volatile or effect a constituent change, as in gasoline or milk. My selfsealing tapper is especially adapted for use with such liquids to be dispensed from tin containers, although it may be also used with any other form of fluids equally as well.

I will now describe more fully the detail construction of my device referring to the drawings and the marks thereon.

The casing l is made of tubular metal, approximately the length of the diameter of the container A, and is provided with a hollow L-shaped piercing horn 2 at one end thereof and opening therein. The piercing horn 2 is formed with a sharp pointed end a and side wall ports 2;, positioned in alignment parallel with the casing axis, pointing inward. The horn is preferably made integral with the casing wall, although it may be rigidly attached thereto by any suitable means. A cross rib c is provided within the tubular casing I and formed with a central threaded opening 11 concentric with the tubular casing axis.

vWithin the opposite. casing end is slidably mounted a tubular slide member 3, preferably splined thereto by the key 4, or by any other suitable means, and is also provided with a rigidly attached hollow, L-shaped piercing horn M at the outer end thereof and opening therein. The horn 2a is of like structure as the opposing horn 2 and is positioned with the piercing point a inward and in alignment therewith. Both the casing l and the inclosed slide 3 are provided with

suitable support bars

5 and 6 respectively,

fixedly attached thereto, providing means for retaining the device in the required position on a. can top when'attachingsame. Within the tubular slide 3 is mounted .a threaded valve stem 1, passing therethrough and threadably engaged with the casing cross rib opening d and capable of adjustment therein for telescoping the tubular members I and 3 together as the valve stem 1 is rotated. Flxedly mounted on the inner end of the valve stem l within the open end of the casing i is a butterfly valve block 8. This valve block is fitted to the casing wall opening, being rotatably and slidably mounted therein and is designed to close and seal the piercing horn opening e when rotated thereover. Within the opposite end of the valve stem 1 is formed an air passage ,f positioned to open into the piercing horn opening 9' when the opposite horn opening e is open. A partial rotation of the valve stem 1 will close and seal both ports simultaneously. Any suitable operating handle 9, of any chosen de- .bers together may be substituted therefor. exact lever construction is not material.

. tion and operation is sign, may be fixedly mounted on the outer end of the valve stem I for rotating same, and when desired may be formed and used as a handle member. Suitable sealing caps l0, preferably flexible rubber discs of the vacuum type, designed to lit the can wall contour, are fixedly mounted over each

piercing horn point

2 and 2a and positioned to engage the can wall as the respective points are pierced therethrough and seal the openings. Any other suitable sealing pad may be used if desired. By unscrewing the threaded valve stem 1, the points a of the

piercing horns

2 and 2a may be sufficiently separated to pass over the top end of a tin container when positioned diametrically thereacross, the horn points being positioned to engage the container side walls on opposite container sides. By-screwing the valve stem I into the casing rib threads, the tubular slide members are telescoped together, forcing their respective piercing horn points a through the thin walls of the container A, and

injected within the container chamber, the horn ports b then opening therein. The pierced wall openings being sealed by the sealing caps l0 tightly pressed thereagainst. When the valve stem 1 is rotated, the horn openings e and g may be opened and the container liquid easily poured through the casing open end. A further half rotation of the valve stem will again close and seal both horn openings, and completely resealing the container A.

The Figs. 6, '7 and 8 show the same detachable can tapper as shown in Figs. 1, 2' and 3, except the threaded valve stem contracting means is replaced by pivoted lever mechanism, each of the arms II and I2 being pivotally connected to the tubular members I and 3 respectively, and capable of telescoping the two slide sections together whenever the connected levers are depressed. Any other suitable arrangement of lever mechanism'capable of telescoping the sliding mem- The The sealing valve block Band operating valve stem 1 are omitted in the illustration shown in the Fig. 8. The Fig. 9 shows the same detachablecan tapper as shown in the Fig. 1, but with the threaded stem \contracting means replaced by gear and rack mechanism. The operating gear I3 is rotatably mounted on the casing la and engages the teeth formation hformed on the tubular slide 3a. Any rotation of the gear l3 by the attached operating arm I! will cause the telescoping of the attached slide members la and 3a the same as in the former case. The applicathe same as heretofore described.

An alternate construction is shown in the Figs. 11 to 13. The tubular casing lb is pivotally mounted at one end to a container hinge band l5, and is provided with two hollow conical-piercing horns 20 positioned on the under side at opposite ends thereof. A valve stem 1a is rotatably mounted within the tubular casing lb and is provided with an air port f and butterfly valve block Ba. for the respective horn wall openings, as in the former case. Any substantial rotation of the valve stem Ia will close and seal both ports. By manually depressing the pivoted tubular casing lever member lb, the sharp horn points 20 may be forced through the end wall of any container A and the respective horn ports b injected within the container compartment. The wall perforations being sealed by thesealing caps l0 mounted on the respective horn points as in the former case. Suitable spring arm clamps ii are provided on the container hinge band l5, designed and positioned to engage and retain the tubular casing member lb in a closed position on the container top when once depressed thereon. By rotating the valve stem lb until both horn ports are open, the container liquid may then be discharged therethrough as in the former cases.

The Fig 13 shows a similar operating casing member similar to. lb, but with the valve stem lb omitted, and may be used to replace the valved member when the nature of the container liquid will permit, and when .the port closing is not desired.

It is apparent that my device is subject to various modifications in both-arrangement and mechanical design, without departing from the spirit of my invention, and I therefore claim not only the structure herein illustrated, but any modification thereof that is substantially a sub-.

sitution of parts and sections herein shown. Having fully described my selfsealing can tapper, what I claim as my invention and desire I .wall ports, provided on the outer end of each of said tubular sections and opening into their respective tubular passages, a threaded valve stem rotatably mounted through both tubular sections and threadably connected to one of said sections capable of adjusting said sections one with the other, a suitable handle rotating means mounted on the outer valve stem end for rotating same.

2. A self-sealing can tapper for sealed liquid containers, comprising two tubular sections slidably mounted one within the other, and splined together, a rigid hollow L-shaped piercing horn with wall ports, provided on the outer end of each of said tubular sections, opening into their respective tubular passages, said piercing horn points positioned to oppose each other, a threaded valve stem with suitable air passage, rotatably mounted through the inner tubular section and threadably attached to the outer tubular section capable of forcing said sections together, suitable turning means fixedly mounted on the outer end of the valve stem, and suitable closing means provided on said valve stem for closing and sealtubular casing and slide members each opening into its respective tubular passage, said horn points being positioned opposing each other, a flexible sealing cap fitted over each horn point, a threaded valve stem rotatably mounted through the inner-tubular slide and threadably attached to the outer tubular casing, turning handle means fixedly mounted on the outer end of said valve stem, said valve stem being formed with an air passage leading to the adjacent horn wall opening, valve closing means provided on the opposite end of said valve stem adapted for closing and sealing the horn wall opening in the tubular casing, when same is rotated thereover.
