CAN.
This invention relates' to an hermetic Seal for a can and particularly to that type of hermetic seal in which the can body is provided at its top with an outwardly-extending sealing flange and the cover which sets can.
Other objects of'the invention are to improve generally hermetically-sealed cans all as hereinafter set forth.
In order to give an understanding of the invention l have illustrated in the drawings a selected embodiment thereof which will now be described after which the novel features will be pointed out in Vthe appended claimsf Fig. 1 is a perspective view of a can made in accordance with my invention;
Fig. 2 is a sectional view through the upper end ofthe can and the can top showing them separated from each other; y
Fig. 3 is a sectional view showing the can after it has been sealed;
Fig. 4 is a fragmentary perspective view of the sealing strip.
Fig. 5 is a section on the line 5 5, Fig. 4;4
Figs. 6, 7 and 8 are fragmentary views showing steps in the process of forming the can cover.
1 indicates the can body which is provided with the open top 2 and is also formed with the outwardly-extending lateral sealing ange 3 at the top. The can top or can cover is indicated generally at 4. and it is of the type which is adapted to fit tightly into the open top 2of the can 1. This can top is also provided 'with the outwardlyextending lateral sealing flange 5 which is adaptedv to overlie the sealing flange 3 of the can body when the cover is in place, a gasket 6 preferably being employed between cover thus facilitating the opening of the Applica/nim mea January 5, 1925. serial No. 514.
the sealing flanges to assist in making a tight joint.
The two sealing flanges 3 and 5 are held in their sealing relation by means of a U- shaped sealing strip 7 which embraces the flanges and clamps them tightly against the gasket 6. 4 v V To hold the sealing'strip in place I have formed the cover 4 with a locking flange 8 which extends outwardly from the inner edge of the sealing flange 5 and is adapted to overlie the upper leg 9 of the fsealing strip. The outer peripheral edge 10 of the locking flange 8 is bent downwardly to partially embrace the sealing' strip thereby to hold it firmly in place. When the cover top is first made the locking flange 8 will have a fiat shape as shown in Fig. 2 and will be spaced from the sealing flange 5 so as to form a groove 11 into which the upper leg 9. of the sealing strip may be inserted during the can-sealing operation.
The locking flange is of suliicient width so that it projects slightly beyond the sealing 'strip as shown in dotted lines Fig. 3 and after the sealing strip is in place the edge 10 of the locking flange is spun downwardly to engage the outer rounded face of the sealing strip and thus lock said strip firmly in place.
A convenient way of making the cover 4 with both the sealing flange 5 and the locking flange 8 is illustrated in Figs. 2, 6, 7 and .8. The first step in the operation of making the can top will be `to form it with the up-standing peripheral flange 15 as shown in Fig. 6. This flange is then acted on by suitable dies so that a portion thereof intermediate its edge is bent outwardly as shown in Fig. 7 and the two sides 12 and 13 of the outwardly bent portion are then pressed together to form the sealing flange' 5. Subse uently the u per portion of the can top is ent outward y to form the flange 8 as illustrated in dotted lines Fig. 8 and in Fig. 2. This flange 8 is so shaped that it is separated from the sealing flange 5 by the Y groove 11. The .sealing flange 5 of the cover is thus made of double thickness and the locking fla-nge 8 is connected to the sealing ,flange at the inner edge thereof.
tion transverse thereto to press them firmly together and during this operationthe peripheral edge 10 of the locking strip may be bent into its locking engagement with the sealing strip.
To facilitate opening of the can I propose to form the sealing strip with an extension 14 whichl will preferably be circular in cross section. After the sealing strip has been inserted in place the extension 14 thereon may be bent to lie against the can body either by bending it downwardly as shown in Figs.
1 and 3 or by bending it laterally to lie under the sealing flange.
When the can is to be opened the extension 14 will be grasped and pulled outwardly and in this Way the end of the sealing strip to which the extension is secured will be withdrawn from its sealing engagement with the sealing flanges. During such withdrawal the peripheral edge 10 of the looking strip will be bent upwardly suiiciently to allow the sealing strip to be withdrawn. The withdrawal of the sealing strip proceeds progressively around the can and during this withdrawing operation the sealing strip will apply upward pressure on the locking flange which will, tend to loosen the can cover so that when substantially the entire length of the sealing strip has been withdrawn the cover will be found to be loose in the can top and may be easily removed.
The advantage of having the extension 14 cylindrical or round in shape is that it can be freely handled in opening the can without danger of injury to the person using it.
l claim.
1. In a can, the combination with a can body having a laterally-extending sealing flange, of a `can cover having a vertical wall portion adapted to lit within the open top of the can body, said wall portion having formed therein an outwardly-extending fold which constitutes a two-ply sealing ange toy cooperate with the sealing flange of the can body, a U-shaped sealing strip embracing said sealing flanges, the upper edge of the wall portion of the cover being bent outwardly to form a one-ply looking flange which overlies the upper leg of the sealing strip.
2. In a can, the combination with acan body having a laterally-extending sealing flange, of a can cover having a vertical wall portion adapted to fit within the open top of the can body, said wall portion having formed therein an outwardly-extending fold which constitutes a two-ply sealing flange to cooperate with thesealing flange of the can body, a U-shaped sealing strip'enibracing said sealing flanges, the upper edge of the wall portion of the cover being bent outwardly to form a one-ply locking flange which bverlies the upper leg of the sealing strip, and the peripheral edge of said locking flange beingA bent to partially embrace the sealing strip thereby to lock the latter in place.

In testimony whereof, l have 'signed my name to this specification.
