UNITED STATES PATENT QEEICE.

GEORGE J. RECORD, or CONNEAUT, Ol-IIO.

SEALING-CAP FOR CANS OR OTHER RECEPTACLES.

SPECIFICATION forming part of Letters Patent No. 584,892, dated June 22, 1897.

Application filed December 28, 1896? Serial No. 617,289. (No model.)

appertains to make and use the same.

This invention relates to double-sealed necks for cans and other liquid-receptacles;

.and it consists in the construction and combination of parts hereinafter particularly set forth and claimed.

In the accompanying drawings, Figure 1 represents a vertical section of a tubular neck and seals embodying my invention. Fig. 2 represents a similar view of a modified form thereof. Fig. 3 represents a similar view of a modified form thereof in which the spout is a vent also, and Fig. 4 represents a detail View of the lower seal.

A designates the upper part of a can or other receptacle; B, a tubular neck or nozzle therefor; O, the upper seal, and D the lower seal.

The cap or upper seal 0 is, screw-threaded, as shown at O, to engage the correspondingly screw-threaded enlarged upper part B of the said neck and is provided with an outlet,

preferably a spout, which may have the common inclined or curved form shown at E and E, Figs. 1 and 2. The lower and less expanded part of the said neck is provided with a portion of greater or less diameter than the remainder, preferably forming a groove 1) for engagement with the lugs or projections d of the resilient lower seal D. These are sprung into engagement, as explained in my reissued Letters Patent No. 11,382, dated November 7, 1893, and my Letters Patent No. 509,098, dated November 21, 1893; but in some respects the most desirable construction is that shown in Fig. 3, which has the middle of the upper cap bent up into a dome or conoid D, with an outlet-opening d in its center. This outlet communicates with the interior of a transverse spout F, which is fastened to said conoid. Both ends of this spout are open, so that either one may be used to pour from, the other becoming the vent. The said spout is attached rigidly to the conical middle part of the seal as well as to the raised annular part of the seal at two opposite points of its periphery. The spout F is therefore strongly braced at three points and practically integral with the said upper seal.

The lower seal D is provided with an annular external groove about the middle of its vertical wall, said groove receiving a packing-ring O, which fits tightly against the smooth inner face of the lower part of the neck a little above the groove 1) and more perfectly prevents the leakage of any liquid. This seal is used with all the forms above shown and described.

The neck or nozzle constructed as above described constitutes in any of the said forms a screw-neck adapted to be sealed either by screw-cap or resilient disk, or by both, or by neither. It is left entirely open for filling. Itis used without the resilient seal for pouring off, and it is used with the resilient seal and the upper seal or cap also for shipment and storage, or in some instances for this last purpose the upper seal or cap may be advantageously dispensed with.

Between the upper screw-threaded part B and the lower grooved part B the neck is provided with ahorizontal shoulder B The upper edge of the lower seal D is bent over on this shoulder, forming an annular flange d and the upper seal, when screwed home, bears against this flange. The shoulder thereby braces both of these seals, and the upper seal aids in holding the lower seal perfectly in place.'

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

1. In combination with a can-neck having an enlarged screw-threaded upper part and a lower grooved part, a screw-threaded upper seal, a packing-ring, and a resilient lower seal provided with projections for engaging the groove of the said lower part, the said lower seal being further provided with an annular external groove for receiving the said packing-ring and the latter fitting against the inner surface of the neck substantially as set forth.

2. In combination with a screw-threaded part and an intervening shoulder, a resilient seal having a rim bent over on the said shoulder and projections whichsnap into the said groove, and an upper seal'which screws into the threads of the neck aforesaidandis pro? vided with a double spout in the form of a 15 tubeopem at both endsand a conoidal middle part which is rigid with the said spout and communicates with the interior thereof,

the said spout being also rigidly attached near its ends to the wall of the said seal at 20 oppositepoints of theperiphery of the latter.

In testimony whereof I affix my signature in presenccof two Witnesses.

GEORGE -J. RECORD.
