Description

March 1, 1932, L. HIRSCH ET AL METHOD OF MANUFACTURING CAN CLOSURES Filed April 4, 193
INVENTCRS.
ATTOR IEY Patented Mar. 1, 1932 s'rAT s PATENT OFFICE LEONARD HIBSGH, OF LYNDHURST, AND EDWIN A. HARRISS, OF ORANGE, NEW JERSEY, ASSIGNORS TO R. B. DAVIS COMPANY, OF HOBOKEN, NEW JERSEY, A CORPORATION OF NEW JERSEY METHOD OF MANUFACTURING CAN CLOSURES Application filed April 4, 1930. Serial No. 441,448.
This invention relates to a novel and improved method of forming a metal closure for cans, and will be best understood from the following description and the annexed drawings, in which we have shown a selected way of practicing the invention and in which Fig. 1 is a view partly in elevation and partly in section showing the top of a can having applied thereto a closure made according to our novel method. 7
Fig. 2 is a section on the same plane as the sectional part of Fig. 1, showing a portion of the closure on an enlarged scale, before attachment to the can.
Figs. 3, 4, 5 and 6 are views showing successive steps followed in making the finished closure.
In Fig. 1 is shown a can 1 having a top 2 to which is applied a sealing member 3, this sealing member extending across the bottom of a recess 4 surrounded by a cylindrical wall 5, and adapted to receive a plug 6. The top may be secured to the can by a suitable seam 7.
The top is preferably formed, as shown in Fig. 3, with the cylindrical wall 5, this form being achieved by action of suitable dies upon a blank of sheet metal. Then, the cylindrical wall is flared outwardly, as indicated at 8. The flare which is shown exaggerated in the drawings, has a function which will be described presently.
The sealing member 3 forms the bottom of the recess, and has its edge portion formed into a circumferential flange 9, so placed as to fit over the flared out edge portion 8 of. the wall 5. After being placed in the position shown in Fig. 5, the flange 9 and flared out edge portion 8 are soldered together, the solder being indicated at 10.
l/Vhen the contents of the can are to be used, the relatively fragible seal 8 may be punctured and removed, and after some of the contents are removed, the plug 6 may be replaced to temporarily close the can, it of course being understood that the plug is first removed before puncturing the sealing member.
We claim The method of manufacturing a can top which comprises forming the top with a hole flange.
