application and sealing of the inner lining. The
present construction secures this result, as will be
now set forth.`
The cil proof lining 2 is first secured to an inner 25
paper lining 3 by any of the usual laminating
processes suitable and well known for the pur
pose. ' The lining2 may be secured to the backing
3 by the well known thermoplastic cements. The
edge of the backing 3y is protected by folding the 30
oil proof sheet about the edge of the backing as
shown at I in Fig. 4. The paper which is em
ployed is readily adhered to the inner turns of
the body during the process o_f making. the‘tube, 35

The end of the container gives a serious prob
lem in the manufacture of a satisfactory oil
proof container. In the form shown, the ends
are closed by round metal caps or disks 6, the
outer peripheries of which are provided with
channels ‘I in which the edges of the container
are seated.
The rim of the disk is turned over to
provide the curled edge 18 and this is crimped
25 against the outer Wall.
The channel is made
somewhat deeper than is customary, and this
provides for an additional and supplemental
crimp ID about the can. A coating of a suitable
lute or filler I2 is applied about the inner wall of
30 the channel as a part of the sealing operation.
In the ordinary can of this type, the center of
the cap or disk is usually Within the plane of
the edge portion. It has been found that this
construction gives rise to leakage due to the
35 heavy character of the contents, as the weight
of the oil on the unsupported ~central area of the
disk causes it to spread at the seal. To obviate
this objectionable feature, the cap in the present
construction is supported byaextending it flush
with or slightly beyond the plane of the lower
edge of the can. Such an expedient is shown in
,I Fig. 1 in which the disk is formed >with a, cir
cular rib I4, which affords a support for the disk
and prevents spreading of the seam. Any suit
