CAP For; CAN S SPECIFICATION forming part of LettersPatent No. 509,098, dated November 21, 1893.

Applicationfiled June, 1893. Serial No. 477,789. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE J. RECORD, a citizen of the United States,residing at (Jon- .neaut, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Caps for Cans; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is in part an improvement on Letters Patent No. 47 6,309, granted to me June 17, 1892. Said Letters Patent related more particularly to the sealing of nozzles of cans for oil or other liquid though not exclusively restricted thereto.

The chief object of the present invention is to provide satisfactory similar means for sealing the inlet through which the liquid is supplied to the interior of vthe can, this inlet being preferably a screw neck having removable screW-cap, and the latter being provided with a small nozzle and air-inlet apertures in order that it may be used also for pouring out the liquid as desired. To this end I employ the construction and combination ofdevices hereinafter more particularly set forth and claimed.

In the accompanying drawings, Figure 1 represents a perspective view, taken from the inner side, (if a screw-cap constructed accord- Fig. 2 represents a similar view of the seal used therewith in one form of the said invention. Fig. 3 represents a similar view of the tubular screw-cap. Fig.

' irepresents a central vertical section through the devices shown in the three foregoing figures when put together for use in sealing the inlet. Fig. 5 represents a detail perspective view of another form of the screw,having its top closed integrally so as to need no other seal; and Fig. 6 represents a detail perspective view of a thin sealing disk which is sometimes substituted for the seal before described and used with the open screw and the screw- Adesignates the screw neck through which the receptacle is filled with liquid. B designates the screw cap which turns on and off this screw and is provided with a nozzle B also with air inlets b b, respectively in the top of the nozzle and in the top of the cap below it. A larger opening b permits the liquid to flow out of the can through the said cap to and through the said nozzle. 0 designates a seal of thin metal, approximately shaped like a plate, provided'with a flange'c, which rests on a lower inturned flange b of the upper part of the said screw and having on its periphery small beads or lugs c, which snap under the said flange b The operation is the same as inthe patent aforesaid and is attended by similar advantages. After the can or other receptacle has been filled through the said tubular screw, the seal is snapped in place and the screwcap is turned home. At any subsequent time the screw-cap may be unscrewed, the seal cut away, the screw-cap replaced, and the liquid poured out through the nozzle B. Of course the seal may also be used with a cap having no nozzle. Sometimes, as shown in Fig. 5, I dispense with a separate seal, and cover the top of the screw neck A with a plate A, the two being'integral. This plate is itself a very eflfective seal, and, being thin,

may easily be ,cut away. The screw cap B is applied, removed, and used as before. Also, I sometimes substitute a thin sealing disk D (Fig. 6) for the seal before described securing it to the inner face of the screw-cap by adhesive material or in any other convenient way, so as to close the 'air vent and liquid outlet. So long as the screw-cap is in place and this disk or lining is intact the tubular screw is sealed. By removing the screw-cap, cutting away the disk or lining and replacing the screw-cap the receptacle is made ready to pour out its contents through the spout A. When the seal 0 is used, it is preferably surrounded by a rubber gasket E for greater tightness; but this is not indispensable.

This invention is very serviceable for petroleum cans, harness oil cans and in fact all receptacles of fluids that are to be sealed and stored or transported; especially if they are to be used for supplying less quantities'through the same aperture which is served for filling them. Of course the tubular inlet and its cap need not be screw-threaded; any ordinary means of attachment allowing removal being used instead.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A receptacle having a filling opening and a screw-neck for said opening provided with an internal flange, in combination with asealing disk 01' seal of thin material having projecting parts which snap under the said flange and hold the sealing disk or seal against withdrawal substantially as set forth.

2. A receptacle having an opening surrounded by an inwardly extending flange, in combination with a sealing disk or seal of thin material having projecting parts which snap under the said flange and hold the seal-
