0 ill. Garrzwzb INV ENTOH ATTORNEYS Patented Mar. 11, 1952 CAN COVER. AND PERFORATOR WITH POURING s-roo'rs Leah L. Garneau, Babbitt, Nev. Application February 24, 1947, Serial No. 730,339

1 Claim.

This invention relates to a combined can cover and can perforator, the primary object of the invention being to provide a cover which may be fitted over one end of a can containing liquid, such as evaporated milk, the device being provided with means for perforating the can top, providing openings to permit the pouring of the contents of the can therefrom.

Another object of the invention is to provide perforated tubes which have their outer ends formed into spouts to permit the pouring of the contents of the can with facility.

Still another object of the invention is to provide means for causing the cover to be secured to the can top to insure the can top being held in close engagement with the can top to exclude air.

Still another object of the invention is to provide closures for the pouring openings, the closures being so constructed that they will operate simultaneously to either open or close the spouts.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing:

Figure 1 is a plan view of a can over and perforator, constructed in accordance with the inven: tion, the pivoted closures being shown in dotted line position as closing the spouts of the device.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a bottom plan view of the cover.

Referring to the drawing in detail, the device comprises a body portion in the form of a cap 5, which is of a diameter to fit over the usual evaporated milk can.

The body portion or cap is formed with threaded openings, in which the threaded hollow shanks 5 of the pouring spouts l are positioned. The mouths of the pouring spouts are so arranged that they have elongated portions or lips 8 to permit the liquid contained'in the can to be poured with facility.

As clearly shown by Figure 2 of the drawing, the inner ends of the hollow shanks 6 are supported, providing piercing points 9 adapted to pierce the can top over which the can is positioned, providing openings through which the contents of the can may be poured.

Formed in the outer surface of each of the hollow shanks, and disposed at a point within the body portion or cap 5, are annular grooves I0, which are so located with respect to the piercing points 9, that portions of the can adjacent to the openings formed by the piercing points 9, will spring into these grooves and hold the body portion or cap 5 in position on the can. Washers I l are provided on the shanks 6 and are disposed between the outer edges of the grooves l0 and inner surface of the top of the body portion or can 5, the Washers fitting against the can top with which the device is used, adjacent to the openings formed in the top, to seal the connection between the body portion or cap 5 and the can top, insuring against the contents of the can leaking at this point.

Secured to the body portion or cap 5 and mounted on the upper surface thereof, is a circular bearing member I2 that provides a support for the pivoted closure member l3 which is formed with an annular flange 4, of a diameter to closely fit over the circular bearing member I2.

The closure member l3 has a central enlargement portion l5 and oval-shaped members l6 adapted to fit over the pouring spouts l to close the pouring spouts. Enlargements I! are formed on the under surfaces of the oval-shaped member l6 and are so arranged that they will exactly fit within the pouring spouts I, closing the spouts.

The central enlargement portion l5 of the closure I3 is formed with a recess in which the pivot bolt [8 is mounted, the threaded end of the bolt [8 being fitted in a threaded opening of the circular bearing I2. A coiled spring, indicated at l 9, is mounted in the recess and engages the head of the bolt l8, tensioning the closure l3 to force the closure l3 inwardly towards the pouring spouts.

An arcuate shaped grooved 2D is formed in the under surface of the enlargement 15, the groove 20 being designed to accommodate the lug 2! that extends upwardly from the bearing member I2, as shown by Figure 2 of the drawing. Thus, it will be seen that due to this construction, rotary movement of the cover l3 on the pouring member 12, will be limited, insuring against the covei being moved too far.

From the foregoing it will be seen that due to the construction shown and described, I have provided a cover which, when positioned over the top of a milk can, will not only seal the openings formed by the piercing elements of the tubes, but will provide a closure to close the spouts of the tubes, excluding foreign matter and air which would otherwise contaminate the contents of the can while the can is in use, as a means for containing and pouring liquids.

Having thus described the invention, what is claimed is:

A can cover and perforator, comprising a cap adapted to be positioned over a can top, piercing tubes secured to the cap, the inner ends of the tubes being pointed providing piercing points adapted to out openings in the can top with which the cap is used, spouts formed at the outer ends of the tubes, a bearing member disposed centrally of the cap, 2. lug extending upwardly from said bearing member, a closure having a central opening fitted on the cap, a depending annular flange formed centrally of the closure fitted over said bearing member rotatably supporting the closure on said bearing member, said closure having a groove formed in the lower surface thereof in which said lug moves, restricting rotary movement of the closure on the cap, and a spring controlled pivot pin rising from the bearing member, disposed in said central opening of the closure, normally urging the closure into contact with said spouts, closing the spouts against the atmosphere.
