LEONARD HIRSGH, OF LYNDHURST, AN D EDWIN A. HARRISS, OF ORANGE, NEW JERSEY, ASSIGNORS T R. B. DAVIS COMPANY, OF HOBOKEN, NEVI JERSEY, A CORIPORATION 0F NEW JERSEY GAN CLOSURE Application filed. February 4, 1930. Serial No. 425,747.
which we have shown a selected embodiment of the invention and in which Fig. 1 is a view partly in elevation and partly in section showing the top of a can having the novel closure applied thereto.
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, 6, 7, 8 and 9 are views showing successive steps performed on a blank to transform it into the closure.
Referring first to Fig. 1, we have shown the invention as used in connection with a can 1 having a top designated generally at 2, and which is secured to the can at 3 by any suitable means such as a double seam. This top forms a closure for the can and is preferably provided with a central recess 4 adapted to receive the plug 5.
In the bottom of the recess is disposed a frangible sealing member 6 which may be v made of any suitable material which can be easily cut with a knife, preferably without leaving a ragged edge. This'material may be paper, cardboard, cellophane, thin aluminum, or the like, it being understood that the top is of sheet metal or relatively non-frangible material.
Referring now to Figs. 3 to 9 inclusive, in Fig. 3 is shown a blank with which the method of forming the closure may start... this blank being in the form of a cup-shaped member having a flat bottom 7 surrounded by a. cylindrical wall 8, this bottom and wall defining a recess. By the neXt operation, the bottom is depressed, as shown in Fig. 4-, and the cylindrical wall 8 is made of smaller diameter, a flange 9 being formed at the same time. The cylindrical wall is shown as extending in a vertical direction, and in the claims it will be referred to as vertically extending, this being done for the sake of convenience in defining relative parts of the structure, and not for the purpose of limiting the invention.
By the next step, the flange is formed with a gutter 10, as shown in Fig. "5, and by-the following step the bottom 7 is brought to the.
position shown in Fig. 6, the wall 8 being folded back on itself to form an edge 11 in the shape of a fold, it being noted that this edge is displaced from the bottom in a direction lengthwise of the wall 8. i
-The bottom 7 is then provided with an opening with its edge 12 folded downwardly as seen in Fig. 7, and by the next step this edge is folded toward the Wall to form the head 13. The sealing member 14 is then placed against the bead and. the folded edge 1.1 is bent inwardly at the same time that the bead 13 is bent downwardly and outwardly toward the folded edge 11, to the position shown in Fig. 9. The result is a one-piece can top having an opening therein closed by a sealing member secured to the top adjacent the opening by a permanent mechanical air-- tight joint. This combination is claimed more broadly in our copending application, Serial No. 351,068, the present application claiming a detailed change in the construction disclosed and claimed in said copending application.
It will. be seen that the bead 13, as well as the folded edge 11, extend transversely to the plane of the sealing member, and that the sealing member is received within the space between these two elements, being bent twice in reverse directions, first around the head 13 and then around the folded edge 11. arrangement the sealing member is clamped between two smooth elements overlapping one another, and while these elements lock the bent edge portion of the sealing member between them, nevertheless there is no ragged out edge of metal to contact with the sealing member. Moreover, the construction is one which may be easily made by suitable dies, without the dies at any time coming in contact with the sealing member which is protected at all times from the dies. At the same time, when the frangible sealing mem- By this posed rough edge which might cause damage to the hands of a person'opening the can.
The joint between the sealing member and the top may be made still tighter by placing a suitable sealing compound in thespace between the bead and-the folded edge, or by using a sealing member which is coated with paraffin, or the like, which will be heated during the sealing step and thus flow into the spaces between these two elements. In any case, automatic sealing machinery may be used in practicing the invention.
While we have shown the invention as applied to the top, it is to be understood that, if
desired, it may be applied also to the plug, in which case of course the contents will be permanently exposed or some other temporary closure provided therefor.
We claim 1. A can closure having a recess surrounded by a vertically extending wall of sheet material, said wall having its lower edge turned inwardly to constitute a wall edge portion and said recess having a bottom spaced along the wall from said turned in lower edge of the wall, said bottom having an opening therein, said bottom adjacent the opening being folded back to constitute a folded edge p0rtion, and a sealing member extending across said opening and engaging the lower surface of said folded edge portion of the bottom,
said turned in wall edge portion engaging said sealing member and holding it against said folded edge portion of the bottom.
2. A can closure having a recess surrounded by-a vertically extending wall of sheet material, the lower edge of said wall being in the form of a fold turned inwardly, one layer of said fold being disposed inwardly of the other and terminating in an inwardly extending portion constituting the bottom of said recess, said bottom having an opening therein, said bottom adjacent the opening being folded back and turned downwardly to constitute a folded edge portion, and a sealing member extending across said opening and engaging the outer surface of said folded edge portion of the bottom, said turned in fold at the lower edge of said wall being disposed between said wall and said folded edge portion and engaging said sealing member and holding it against said folded edge portion of the bottom.
