CAN-CLOSURE.

Specification of Letters Patent. lyatented Mfay 18, 1915.

Application filed August 2, 1913. Serial N 0. 782,603.

To all whom it may concern:

Be it known that I, DANIEL B. TAMAGNO;

a citizen of the United States of America, residing in the borough of Manhattan, city, county, and State of New York, have invented a certainnew and useful Improved Can-Closure, of which the following is a specification.

This invention relates to a telescoping pouring spout which in depressed position forms atight closure for the. can.

The axis of the spout may be disposed at an angle, as hereinafter appears, and, being preferably placed in the cover at one corner of the can, it is possible to pour from the spout substantially the entire contents of the can.

In the accompanying drawing: Figure 1 is a plan view showing one angle or corner of a can: Fig. 2, a vertical longitudinal section: Fig. 3, a section indicated by the line A, B, of Fig. 2: Fig. 4, a detailed transverse section on the line C, D, of Fig. 2. Fig. 5, a detailed longitudinal section showing a slight modification: and Fig. 6, an elevation thereof.

1 indicates the sidewall of a can and 2 the top thereof. Formed in thetop is a circular aperture 3 closed by a cover disk 4 which has a depression 5 to receive a hinged handle or draw loop 6 and also an aperture to receive the pouring spout and associated part. This aperture 1s, in the preferred construction illustrated, rectangular in cross section. On the under side of the disk 4 and surrounding the aperture therein is a correspondingly shaped tube 8 closed at the bottom 9 and having a port 10 on the side adjacent the angle or corner of the can and a smaller vent port 11 in the opposite wall. This tube is fitted to the under side of the flat partof the disk 4 and conformed to the under side of the depression 5 and is secured thereto by solder 12 so as to form a hermetically sealed joint. In forming the port 10, which is rectangular, a surrounding edge of the stock of the square tube 8 is thrown inwardly, the flange so formed being marked 13. Above the flange is set a flat rectangular packing or gasket 16 which is firmly held in position by the parts named and by contact with the two walls of the tube 8 that are at right angles to the wall in which the port is formed. This packing is of appropriate material and of a thickness somewhat greater than the depth of the flange 18. Inside of the tube 8, opposite the side in which the port is formed, is the vent-opening 11 around which the stock of the tube is turned inwardly to form an interior flange which may be circular or rectangular. Surrounding the flange of the vent-opening is a flat packing 17 held in position by said flange and disposed between it and the adjacent bottom face of the covered disk 4: and supported at its edges by the adjacent side walls of the tube 8.

Fitted :to slide in tube 8 is a telescoping pouring spout 18 in close sealing relation to the oppositely disposed packing and having at its upper edge the hinged handle 6. The bottom of the telescoping spout which, when in depressed position, rests upon the bottom 9 of the tube 8 is formed with flanges 19, 20, at least upon the opposite sides in which respectively are the port- 10 and vent 11: and the bottom of the telescoping spout 18 is inset or countersunk, as shown at 21. Immediately above the bottom or floor of this inset on one side is a port 11 adapted to register with the vent 11; and,on the op 0- site side, a port 10 adapted to register with the port 10. The floor of the inset 21 is inclined from the vent wall of the spout to the opposite wall containing the port 10-. WVhen the spout is drawn out, as indicatedin dotted lines, its outward position is determined by abutment of flange 20, for instance, against the inset rib 15 in the outer tube 8 and, when so positioned, the port 10 is coincident with the port 10 and the port 11 is coincident with the vent-opening 11.

Figs. 5 and 6 indicate slight modifications, that is to say, instead of the rib 15 being formed as shown in Fig. 2 by an inset having double parallel walls, it is made by forming an offset 22. On the vent side of the tube 8 there are similar offsets 23, 2 1 both above and below the inturued flange surrounding the vent-opening 11. The opposite walls of the sliding or telescoping spout thereupon have flat packings 16, 17 and are held out of contact with the inner surfaces of the opposite walls of the tube 8 in which the packings are set. The two other or transverse walls of the sliding or telescoping spout may run in contact with the corresponding walls of the tube 8. The flanges 19, 20, which may be placed on all four sides of the sliding spout at its inner end, fit the interior of the tube 8 and cause the spout to slide in a right line thereby preventing uneven strains or' pressures upon the packings. The walls, both of the outside fixed tube 8 and the interior telescoping or sliding spout, have more or less elasticity which facilitates an accurate fit of the packing surrounding the port. 10 and that surrounding the vent with the walls of the spout. When, after pouring, the can is returned to upright position, any material remaining in the spout will be directed by the floor of the inset 21 through the ports 10, 10 to the interior of the can after which the spout may be pressed down into innermost position.

' v The material of which this structure is made may be varied. For liquid contents,

, able adhesives or other means of fastening may be employed instead of solder.

I claim: I 1. A can closure comprising a tube extending into the can from the top thereof, a port in one side thereof adjacent the top of the can, packing surrounding. the portandheld in fixed relation thereto by inset 'ribs or flanges, a telescoping pouring spout fitting within said tube, having a port adapted when the spout is drawn out to register with the port in the fixed tube, the wall of the spout in which said port is located moving in intimate contact with said packing, said spout also having a bottom or floor which when the spout is drawn out is substantially opposite the bottom edge of the two said ports.

2. A can closure comprising a tube extending into the can from the top thereof, a port in one fiat side thereof adjacent the top of the can, a flat packing surrounding the is drawn out is substantially opposite the bottomedge of the two said ports.

3. A can closure comprising a tube extending into the can from the top thereof and which is rectangularin cross section, a

port adjacent the top of the can in one flat wall of the tube. and a vent substantially opposite said port in the opposite flat wall of the tube, flat packings surrounding theport and vent, means on the tube for looking or holding the packings in position, and a telescoping pouring spout having flat walls slidable within the tube in contact with the packings and provided with port and vent openings adapted to aline with the port and drawn for pouring.

A can closure comprising a rectangular tube extending into the can from the .top thereof, a port in one of the flat Walls of the vent of the tube when the spout is withtube adjacent the top of the can and a vent I in the tube substantially opposite said port,

packings surrounding the port and vent,v

means in the tube for holding the packings in position, a telescoping pouring spout slidable within the tube and having oppositeflat walls that run'in intimate contact with the packings surrounding the vent and port and havlng corresponding vent and port openings adapted to be brought opposite said port and vents when the spout is withdrawn for. pouring, said spout being otherwise closed except at its mouth and having a bottom or floor closely adjacent the lower edge of the port-opening therein and inclined downwardly toward said port.

In testimony whereof, I have hereunto subscribed my name.

DANIEL B. TAMAGNO.
