INVENTOR I ATTORNEYS WITNESS Patented Nov. 16, 1937 UNITED STATES PATENT OFFICE CLOSURE .AND POURING DEVICE Edward lo. Sohaetzel, Alhambra, Calif. Application September 8, 1936, Serial N0. 99,808

2 Claims. (01. 221-18) This invention relates to closures for containers, and its general object is to provide a closure device in the form of a pouring spout that is primarily designed for use with cans of the kind that include segmental flanged or lug bearing nipples, to rotatably receive like type caps for closing the same, and my device is applied to the nipple of such cans when the cap is removed therefrom, to not only facilitate the pouring of the contents from the can but to act as a closure therefor, when not in use, in that the device includes a gravity actuated valve that operates automatically to open position when the can is tilted to pour the contents therefrom and to closed position when the can is returned to its normal position.

A further object of the invention is to provide a closure device, in the form of a pouring spout, that can be applied to the can in an easy and expeditious manner, is simple in construction, 20 inexpensive to manufacture and extremely efficient in operation, use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the ac- I companying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing 30 wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a sectional view taken through the closure device which forms the subject matter 35 of the present invention and showing the same applied to a can and in normal or closed position.

Figure 2 is a top plan View thereof.

Figure 3 is a view similar to Figure 1, showing the closure device in open or operative position.

40 Figure 4 is a sectional view taken approximately on line 4-4 of Figure 1, looking in the direction of the arrows.

Referring to the drawing in detail, the letter A indicates a can of the usual square corner 45 type, with the usual nipple B secured thereto adjacent one corner thereof, the nipple having a right angle segmental flange or right angle arcuate lugs C formed on its upper end and sur- 50 rounding the same, as clearly shown in Figures 1 and 3. The nipple structure is well known, and is adapted to receive caps having like lugs for engagement with the segmental flange or lugs C.

My closure device is applied to the nipple 55 when the cap is removed therefrom,and includes a hollow funnel like body I tapered inwardly toward its upper end, and formed on the lower end is a skirt 2 which in turn has formed thereon and extending inwardly at right angles with respect thereto lugs 3 to contact the lower edges 5 of the lugs C, it being obvious that in applying my closure device to the nipple, the lugs 3 are first disposed between the lugs C, thence the device is rotated for disposing the lugs 3 under and in contacting engagement with the lugs C as clearly shown in Figure 1.

The lugs 3 are preferably upturned at one of the ends thereof to provide stops 4 to contact the corresponding ends of the lugs C as clearly shown in Figure 4, but both the lugs C and 3 may 15 be inclined in opposed directions to set up a cam action, as will be apparent.

Secured adjacent the lower end of the body I is a ring disk 5 with an opening arranged in the center thereof, and the edges of the opening are downturned to form a flange 6 which acts as a seat for a ball valve 1, the latter being preferably formed from glass or other non-corrosive material, but in any event when seated upon the flange 6 closes the opening, as will be noted upon inspection of Figure 1. I

Formed on and extending upwardly from the outer edge of the ring disk 5, is a strip 8 which has its upper end curved inwardly as at 9 for disposal in the path of the ball, to act as a stop or abutment means therefor, when unseated, as shown in Figure 3.

Disposed between the ring disk 5 and the lugs 3 is a gasket II], for the purpose of providing a leak proof connection between the upper edge of the nipple and my device, when the: latter is fixed to the nipple, as shown.

From the above description and disclosure of the drawing, it will be obvious that my Closure device can be applied and removed with respect to the nipple in an easy and expeditious manner, and when the can is tilted to the position as shown in Figure 3, the ball 1 becomes unseated to allow the contents of the can to be poured therefrom, but when the can is returned to its normal position, the ball falls by gravity on its seat to close the opening, and thereby retains the contents of the can free from dirt, dust and foreign matter, as well as prevents evaporation thereof, in the event the contents should be of a volatile nature.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be registering with the outlet for the passage of the contents of the container therethrough; a gravity actuated ball receivable by the seat for closingthe opening, and means formed on the disk and VI rising therefrom for disposal in the path of the ball to limit the open position thereof;-

2. The combination with a container having an outlet nipple secured thereto and provided with lugs about the outer periphery thereof, of a closure device for the container and comprising a hollow funnel like body tapered toward one end, inwardly directed lugs formed on the opposite end to contact the lugs of the nipple for securing the device thereto, a disk ring having an opening centrally arranged therein and disposed within said body adjacent the last mentioned end thereof, said opening having its edge shaped to provide a seat and adapted for the passage of 'the contents of the container therethrough, a

ball engageable with the seat to close the opening, and means arranged in the body for disposal in the path of the ball to limit the open position thereof. 1. a v
