ATTORNEYS WITNESSES Patented Dec. 20, 1932 UNITED STATES PATENT oFFlcE EDWARD I1. MCGINNIS, OF HIGHLAND PARK, NEW JERSEY, ASSIGNOR TO CONSOLIDATED FRUIT JAR COMPANY, OF NEW BRUNSWICK, NEW JERSEY, A CORPORATION OF NEW JERSEY SPOUT AND CLOSURE Application led January 15, 1932. Serial No. 589859.

This invention relates to a spout and c10- sure, the object of the invention bemg to provide a spout which is normally closed by an integral end rojecting beyond an annular seat for the dlosure, whereb said annular seat functions as a\guide or an instrument to sever or cut the end 'of the spout to open the spout.

My improved device is especially adapted for use on containers in which highly volatile or dangerous liquids and gases are contained, and functions to absolutely seal the container until the end of the spout is severed, and the closure has an internal annular seat engaging the seat of the spout to close the spout after the end has been removed.

A further object is to provide an improved closure and spout in which the closure has two internal seats, one seat engaging the removable end of the spout and the other an annular seat on the spout removed from the end of the spout, so that both of these seats are engaged by the closure in storage and shipment of the container, and after the end of the spout is removed an efficient and tight closure is had b v reason of the engagement of the closure seat with the seat on the spout.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, all of which will be more fully hereinafter described and pointed out` in the claim.

In the accompanying drawing- Figure 1 is a view in longitudinal section, illustrating my improved spout and closure;

Figure 2 is an exaggerated view illustrating the spout with the end severed; and

Figure 3 is a view partly in elevation and partly in longitudinal section illustrating a modification.

A represents my improved spout and B a closure therefor. These parts are preferably of soft metal. and in most cases are relatively small, the drawing being exaggerated for purposes of illustration` but it is, of course, to be understood that the spout may be as small or as large as may be desired.

The spout A is of general tapering form and hollow, and the outer end of the spout,

which is reduced in diameter, has a longitudinal bore 1 and `,the extremity of the spout is closed, as shown at 2, closing the end of the bore 1. At atpoint removed from the end of the spout screw threads 3 are provided and near the end of the spout an annular shoulder 4 is provided, -constituting a seat and also constituting a guide for the operation of an instrument to sever the end of the spout and open the spout.

The closure B is internally screw-threaded to engage the screw threads 3 of the spout, and is provided with two internal annular seats 5 and 6 respectively.` The seat`5 is of greater diameter thanthe seat 6 and adapted to engage the annular seat 4 of the spout while the smaller seat 6 engages the closed end of the spout, and these seats both engage while the spout is integrally sealed by the closed end. After the closed end is severed, as indicated in Figure 2 of the drawing, the seats 4 and 5 on the spout and closure respectively engage to constitute a tight closure for the container.

In a device of this character where soft metal is employed, these seats become ground by reason of the turning action of the closure on screwing the same into closed position, and even though there may be some slight defect in the shape of these seats in the manufacture of the articles there will be a sufhcient grinding action to insure a per fectly air-tight juncture of the parts.

The spout A may, of course, be secured to a container C in any approved manner. In Figure l I illustrate the spout A as having an enlarged base 7 which is clamped over an outlet spout S of the container C, and a gasket 9 is interposed between the spout 8 and the base 7 to insure a tightjuncture of the parts.

In the modification illustrated in Figure 3 of the drawing, a base 10 corresponding to the base 7. in the form shown in Figure 1, is internally screw threaded. as shown at 1l, to removably engage a screw-threaded spout 12 on the container C, and in this modified form I also employ a gasket 13 interposed between the base 10 and the container spout 12 to insure a tight joint.

While I have illustrated two embodiments of my invention, it is obvlous that various slight changes may be made with regard to the form and arrangement of parts without departing from the invention, and hence I do not limit m self to the precise details set forth but conslder myself at liberty to make such changes and alterations as fairly fall within the spirit and scope ofthe clalm.

What I claim is:

The combination with a spout and a closure therefor having screw-threaded engagement, said closure and spout being composed of soft metal, and the spout between the threaded portion thereof and the extremity being of general tapering form, said spout having a tapering annular seat at a point removed from its extremity, said seat acting as a guide for tools to sever the closed end of the spout and said closure having two tapering internal seats, one engaging the seat on the spout and the other the extremity of the spout.
