46 Keri/5. 1 5755? 3:? 8 J4 BY J19 WZE'WW s Umdam United States Patent Ofitice 2,721,672 Patented Oct. 25, 1955 CAN COVER AND PUNCH Karl H. Fahle, Copper Mountain, British Columbia, Canada Application August 6, 1954, Serial No. 448,255 1 Claim. (Cl. 220-51) This invention relates to a can cover and punch and has for its primary object to protect the contents of an opened can from the collection of dust and dirt.

Another object is to facilitate the rapid opening of a can such as is employed to contain evaporated milk or the like by the punching of spaced holes in the top thereof through which the contents of the can may be removed.

A further object is to maintain the punched openings in the can closed until such time as removal of the contents is desired, and to automatically return the can cover to closed position after it has been opened.

The above and other objects may be attained by employing this invention which embodies among its features a band removably mounted on a can in encircling relation thereto adjacent the top thereof, a handle carried by the band and extending radially outwardly therefrom adjacent one side thereof, a can cover mounted on the handle to move in a vertical arcuate path above the band, a slide mounted on the handle to move across the top thereof, said slide being operatively connected to the can cover for moving it in its arcuate path as the slide moves across the top of the handle, a spring carried by the handle and engaging the slide to yieldingly urge it toward the band and the cover advanced into closing relation to the can, and a punch carried by the cover for piercing the top of the can.

Other features include a guideway carried by the handie and extending longitudinally along the top thereof, a can cover pivotally carried by the handle for movement in a vertical arcuate path above the band, a strip of resilient flexible material mounted in the guideway for movement longitudinally therein, one end of said strip being pivotally connected to the cover for moving it in its vertical arcuate path as the strip moves in its guideway, a slide carried by the strip and extending upwardly therefrom above the handle, a lug carried by the slide and extending downwardly therefrom, a spring carried by the handle and engaging the lug for moving the slide toward the band and holding the cover in closing relation to the top of the can, and spaced punches carried by the cover and projecting downwardly therefrom for piercing the top of the can.

Referring to the drawings in detail, a band 10 is provided with a suitable extensible coupling 12 by means of which the band may be placed in encircling relation about a can C and locked in place thereon. Carried by the band and extending upwardly therefrom is a post 14 of a handle designated generally 16 which comprises a pair of mating handle units 18, each comprising a pair of mating post units 14 carrying at their upper ends outwardly extending arms 20 which are provided in their adjacent faces with longitudinal grooves 22 which, When the handle units are joined together, define a guideway, the purpose of which will hereinafter appear. Carried by the outwardly extending arms 20 and depending therefrom adjacent the outer ends thereof are. mating legs 24 which define a grip about which the hand of the user may be clenched. The arms .20 are provided with mating recesses 26 which open through the upper sides of the arms 20 to define an elongated longitudinal slot adjacent the junction of the arms 20 with the legs 24.

Pivotally connected as at 28 to the handle 16 adjacent the junctions of the post elements 14' and arms 20 is a rock arm 30 carrying adjacent its end remote from the pivot 28 a pad 32 carrying upwardly extending spaced parallel cars 34, the purpose of which will hereinafter appear. Welded or otherwise secured to the pad 32 is a can cover 36 carrying on the side thereof remote from the pad 32 a cushioning ring 38 which, when the cover is closed, is adapted to rest on the top of the can upon which the device is mounted.

Carried by the ears 32 and extending therebetween is a pivot pin 40 to which is pivotally connected one end of a resilient flexible strip 42 which is slidably mounted in the guideway defined by the grooves 22, and carried by the strip and projecting upwardly therefrom adjacent the end thereof remote from the pivot pin 40 is a slide 44 which projects through the slot defined by the recesses 26 to form a thumbpiece by means of which the strip 42 may be moved longitudinally in the guideway. Carried by the slide 44 and projecting downwardly into a chamber in the handle defined by mating recesses 46 is a lug 48 and contained within the chamber is a compression coil spring 50, one end of which bears against the end of the chamber remote from the band 10 and at its opposite end on the lug 48 to yieldingly urge the slide 44 toward the band and the cover 36 into contact with the top of the can C. Extending through the cover 36 are spaced openings 52 for the reception of shanks 54 carried by punches 56 which project downwardly from the underside of the cover 36 and are provided adjacent their lower ends with sharpened edges 58 to facilitate the puncturing of the top of the can C.

In use, it will be evident that the band 10 is clamped about a can C adjacent the top thereof, and while the band is being so clamped, the cover 36 will assume the inclined broken line position illustrated in Figure l with the punches 56 lying above the can top. After having secured the band 10 in place, pressure is exerted on the cover 36 to force the punches 56 through the can top to form spaced openings therein. The forcing of the punches 56 through the can top will cause the cover 36 to move downwardly against the can top as in the full line position in Figure 1 to cause the sealing gasket 38 to rest on the can top and'exclude dust and dirt from the space between the cover 36 and the can top. When it is desired to use the contents of the can, pull is exertedon the slide 44 to move it against the effort of the compression spring 50 and thereby move the cover 36in a vertical arcuate path above the can top and above the band 10 so as to extract the punches 56 from the openings. produced thereby in the can top and permit the user to pour a selected volume of the contents of the can throughv one or the other of the openingsproduced by the punches; After the substance has been. poured from the can, the cover 36 will automatically close upon release of the slide 44 to permit it to advance under the infiuenceofv the spring50 toward the end of the handle member. adjacent the standard 14 and to thereby move the slide. 42 in a direction to move the lever 30 downwardly and. the gasket or cushion 38 into close contact with the top of the can. Simultaneously, with the downward movementof the cover 36, the punches 56 will enter the holes punched thereby in the can top to further seal the contents of the can therein.

While in the foregoing there. has been shown and. described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What is claimed is:

A can cover and punch comprising a band removably mounted on a can in encircling relation thereto adjacent the top thereof, a handle carried by the band and extending radially outwardly therefrom, a guideway carried by the handle and extending longitudinally along the top thereof, a can cover pivotally carried by the handle for movement in a vertical arcuate path above the band, a strip of resilient flexible material mounted in the guideway for movement longitudinally therein, one end of said strip being pivotally connected to the cover for moving it in its vertical arcuate path as the strip moves in its guideway, a slide carried by the strip and extending upwardly therefrom above the handle, a lug carried by the slide and extending downwardly therefrom, a spring carried by the handle and engaging the lug for moving the slide toward the band and holding the cover in closing relation to the top of the can, and spaced punches carried by the cover and projecting downwardly therefrom for piercing the top of thecan.
