POURING SPOUT CONSTRUCTION F OR CONTAINERS Filed Aug. 6, 1959 2 Sheets-Sheet l INVENTCR. KA e4 Gusm'v ANDER sso/v A 7'TORNEX Nov. 6, 1962 K VANDERSSW 3,062,418

POURING SPOUT CONSTRUCTION FOR CONTAINERS Filed Aug. 6. 1959 2 Sheets-Sheet 2 INVENTOR. /\A 84 -0us TA v ,4/v0a sso/v ATTORNEY Claims The present invention relates to a pouring spout construction for sealed containers which are intended to contain more or less viscous liquids, especially oil. Such sealed containers, as a rule called cans, are usually produced in such a way that the can-manufacturer delivers the can with a loose end wall plate, e.g. to an oil company which is to attend to the filling of the can. After the can has been filled the loose end wall is applied and secured by folding. These particular procedures are avoided by the structure according to the present invention. According to the invention the pouring spout construction comprises a base member of plastic or another comparatively resilient material forming a valve casing or seating, which is to be sealingly inserted into the opening of the receptacle for facilitating filling and emptying of liquid, a flat portion and a tubular socket to be sealingly inserted into the vent opening of the receptacle, and a valve member likewise of plastic or another comparatively resilient material and arranged for being rotatably mounted in the valve casing, said valve member being associated with a gutter-shaped portion and a projection for closing said tubular socket.

In said structure according to the invention, the container to be filled is delivered ready-folded and with the base member secured thereto but with separate valve member. After filling of the container the valve member is pushed in manually so as to close the liquid opening as well as the vent opening, and there will be no need for any sealing machine. When it is desired to empty the can completely or partially, the portion of the valve member projecting into the vent opening is pulled out and turned so that the valve member will project over an edge of the container at the same time as the liquid opening is opened and the liquid is permited to drain off. For closing, the valve member is turned back until its projection closes the vent opening.

An embodiment of the invention is illustrated in the accompanying drawings, wherein:

FIG. 1 shows a partial view of a can with a pouring spout structure according to the invention in open position for emptying the can.

FIG. 2 shows a sectional view of part of the can and the pouring structure in closed assembled relationship as seen in FIG. 3.

FIG. 3 shows a partial view of the can with the pouring structure in closed position.

FIG. 4 shows a top plan view of part of the can with the pouring structure.

FIG. 5 shows a side elevation of the valve member forming part of the pouring structure.

FIG.. 6 shows a top plan view of part of the can together with a base member of the pouring structure.

FIG. 7 shows a side elevation of the base member.

FIG. 8 shows a sectional View of part of the can Without the pouring structure according to the invention.

FIGS. 9 and 10 show the valve member and the base member respectively, seen from below.

FIG. 11 shows a side elevation of the valve member as viewed from the left in FIG. 5.

FIG. 12 shows a side elevation of the base member as viewed from the right in FIG. 7.

hates Patent idea According to FIGS. 13 the pouring structure according to the invention is inserted into one end wall of a cylindrical can 1 of tin plate. For this purpose a larger opening 12, FIG. 8, is provided in the end wall adjacent to the peripheral wall, and a smaller opening 13 is provided approximately at the centre of the end wall.

The pouring device comprises a base member having a disc-shaped fiat portion 2, a cylindrical valve seating 3, a tubular socket 6 at one side of the portion 2 (FIGS. 2, 6, 7, 10 and 12). These members 2, 3, 6- are made of plastic or another comparatively resilient material. The valve seating 3 has a bottom 4 and a lateral port 5 opening into a cylindrical valve chamber which is open towards the flat portion 2. The whole base member 26 is mounted in the can 1 in such a way that the flat portion 2 lies contiguously to the outside of the end wall of the can, the valve seating 3 being pressed into the opening 12 of the can and the tubular socket 6 being pressed into the opening 13, so that the valve seating and the tubular socket are sealed against the edges of the respective openings 12, 13. in order for the valve seating 3 to be re tained more reliably in the opening 12, the seating 3 is provided with an annular head 14, FIGS. 7 and 12, which, after being forced through the opening 12, forms a catch against the edge of the opening and prevents the valve seating 3 from being loosened from the end wall. If necessary, also the tubular socket 6 may be provided with a similar head.

A second part of the pouring structure consists of a valve member comprising a cock plug 7, a gutter-shaped portion 8 and a peg 9 or similar projection, FIGS. 2, 4, 5, 9 and 11. These members 7, 8 and 9 are likewise of plastic or another comparatively resilient material. The cock plug 7 has a lateral port 10 and a through-passage open in the bottom of the gutter-shaped portion 8. The plug is rotatably mounted in the valve seating while the gutter-shaped portion 8 lies contiguously to the discshaped portion 2 and the peg 9 is inserted into the tubular socket 6, as shown in FIG. 2. Furthermore, the cock plug 7 has a head 15 which extends into an annular groove in the valve seating 3 and prevents the cock plug 7 from being removed from the valve seating 3. The ports 5 and 10 are equally large, and by turning the cock plug 7 they may be caused to take a position either in complete register with one another or completely separated.

A can provided with the pouring structure described is intended to have its two end walls secured by folding and the base member 26 inserted into one end wall, but the valve member 7-10 is intended to be separate at the delivery to the person who is to fill the can. Filing takes place through the large opening in the valve seating 3 and the port 5, while the air in the can is permitted to escape through the tubular socket 6, the last mentioned fact making a quick filling possible by means of a jet from a filling pipe with a rubber flange engaging the top side of the valve seating 3. When the can is filled, the cock plug 7 is pressed into the valve seating 3, the peg 9 is pressed into the tubular socket 6 and the can will then be efficiently sealed. Possibly the gutter 8 may be locked against rotation by means of a sealing strip 11.

When pouring of liquid from the can is to be performed, the gutter-shaped portion 8 is seized and the peg 9 is pulled out, after which the portion 8 is turned half a revolution, so as to extend over the edge of the can, as shown in FIG. 1. At the same time the port 10 has arrived into a registering position with the port 5. When the can is inclined the liquid will flow out and proceed in the gutter-shaped portion 8 and pass over the edge of the can without touching the edge or dirtying the same.

Simultaneously the air may freely flow into the can through the tubular socket 6.

The pouring device has its flat portion 2 located close to the end wall and the thicker or higher portions, such as the valve seating, cock plug and tubular socket, project into the can. For this reason there is nothing to prevent filled cans with the valve member inserted from being piled one upon the other in storing or transportation.
