9 Claims. (Cl. 22l19) This invention relates to cans or like receptacles, particularly cans for holding oil; and the object of the invention is to provide a can of improved construction (suitable particularly for containing a light, very fluent oil, such as corn oil) which will have a pouring spout that, in the first place, will interfere as little as possible with the packing of the cans in crates or cartons; that,

secondly, will not leak through capillary attraction, that is, through the tendency,,whatever the cause may be-of the oil (which tendency is very marked in light vegetable oils) to creep along the surface with which it is in contact; and that, thirdly, the lip of which is so formed and positioned as to prevent dripp Of the last drop or two upon the top of the can. The spout is rigidly seemed to the can top and lies within the lines defining the edge of the can top; and the spout in accordance with this invention, so as to keep the top of thecan cleanand free from oil in a way which is wholly impossible with cans having spouts which project over the edges of the can, for pouring, and are rotatable so as to be turned to a position within the line of the can top when the cans are crated;

A further object of the invention is to provide a dust cap or cover for the spout to keep dust and dirt from entering the spout, especially after the can top has been perforated to permitthe discharge (at intervals, if desired) of the contents of the can, the dust cap beingso formed, preferably, that when the cans are packed and the crates or cartons containing them are stacked in piles, or otherwise when the cans are subjected to pressure from above, the spouts and the tops of the cans will be reinforced and kept from bending. It is especially important that the spout of a can, where the spout does not project beyond the edge of the can, should not be bent down at its pouring end, since shortening of the distance between the lip of the spout and the can top may bring about a dripping through combined gravity and attraction of the metal of the can top for the oil, a phenomenon which does not occur when a proper distance is maintained between these points and when the lip of the spout is properly formed, as will be hereinafter described. Obviously it is advantageous, in packaging the cans, that the spouts should project above the top of the cans as little as possible.

The invention is illustrated in preferred embodiments in the accompanying drawing, wherein Fig. 1 is a view in perspective of the upper portion of a can provided with a spout construction directly above and dust cap in accordance with this invention. Fig. 2 is a fragmentary vertical sectional view through the spout and adjacent portions of the can top on a plane extending longitudinally of the spout and diagonally of the can.

Fig. 3 is a fragmentary view similar to Fig. 2 showing a. modification.

Fig. 4 is a fragmentary plan view of the spout with the dust cap removed.

Fig. 5 is an inverted plan view of the spout member, and Fig. 6 a fragmentary perspective of the same.

7 is a view in perspective of the dust cap. Referring to the drawing, the can body designated 10 is shown as approximately rectangular 7 in its cross section with rounded vertical edges at 11. The top 12 of the can is seamed in the usual manner to the body 10 to provide a slightly upstanding bead 13. This, and other features of the sort, are necessarily somewhat exaggerated in the drawing in order to illustrate their construction. The seam is treated in the customary manner, of course, so that the oil which, in the case of corn oil, is extremely fluent, will not leak out of the can at the seam. The can top near one corner has a circular opening surrounded by an upturned slightly flared flange 14. In this opening is arranged a cupped seat member 15 which is imperforate and seemed at 16 to the flange 14 to provide a connection which is completely impervious to the oil, the seam 16, being of the same leak-proof character as seam 13. The spout member 17 has a circular portion 18, slightly tapered from top to bottom, which closely fits into the seat member 15 to which it may be secured by solder, as indicated at 18, or in any other suitable manner calculated to make a sealed, rigid connection between the spout member and its seat. The spout member has a pouring lip 19 which slopes upwardly and in the direction toward one corner of the can top. The pouring edge of the lip is downtumed as indicated at 20, the rest of the edge or the spout'member being overlapped upon itself to form a head, as indicated at 21. The pouring edge of the spout is the seam 13 of the can at onecorner thereof, the pouring edge being preferably very slightly within the surface defining the outer side of the seam. The bottom of the spout member may be oflset a trifle upwardly, indicated at 22, Fig. 2, or it may be flat as indicated at 23, Fig. 3. Preferably the bottom is formed with pouring and air apertures 24, 25. These guide the user in perforating the can top when the contentsofthecanaretobedischarged. 'I'hedu t found, however, that this cap 26 is formed with a downturned flange 27, the edge of which is preferably beaded at 28, the flange being made wide enough at the front end so that this end 29 will bear upon the beading 13 of the can top.

Itwillbeseenthatuntilthetopofthecanhas been punched, through openings 24, 25 in the bottom of the spout member, the can is as impervious to the leakage of oil as the ordinary spoutless can. The seat member 15 is seamed to the top 12 in. the same manner as the top 12 is seamed to the body of the can. In practice it has been found impossible to make a can with a revoluble spout that will not leak around the spout and so foul the top of the can. The oil creeps up between the metal parts no matter how closely they may flt. The purpose of having these spouts revoluble was, of course, to makeit possible to have the spout extend beyondthe edge of the can, for pouring, or to have itturned so as to be positioned entirely within the edge line of the can top when the can was to be crated with other cans of like construction.

According to the present invention the spout is rigid, making possible seamed or sealed joints which'prevent any possibility of leakage. This necessitates having the spout within the outline of the can top, or substantially so, otherwise there would be very considerable inconvenience in crating the cans. With the spout so arranged, however, there is danger of the top of the can being fouled by the dripping of the last drop or two of oil from the lip of the spout. It has been dripping may be avoided if the pouring lip is formed with a downturned edge and provided the lip is kept at a distance not less than flve-sixteenths of an inch from the bead on the top of the can. If the distance is substantially less than this the metal appears to have an attraction for the oil outlet which causes it to leave the lip. To save space in the packaging or crating of the cans it is desirable that the spout should project up above the top of the can as little as possible. Hence it is important that the spout and top of the can be protected or reinforced against bending. particularly when crates or other packages of the cans are piled one on top of the other, as will be the case, ordinarily, in storage or shipment. This reenforcement is eifected by forming the flange of the dust cap so that it transmits downward pressure on the cap and spout to the beaded edge of the can. The various expedients of the present invention therefore serve the common purpose of providing a can with a pouring nozzle so constructed as to prevent the fouling of the top of the can by leakage or dripping with the pouring nozzle arranged and constructed so as to minimize inconvenience and the danger oi deformation when the cans are packaged.

The combination of a can provided with a spout and with a beaded upper edge with a dust cap having a flange bearing upon said bead is distion, flied November 28, 1932,
