My invention relates to containers and more

throughout the several iigures.
Referring to Figs. 1-5, the cylindrical body Si
of the container is preferably made of iibrousV
material in laminated or multi~layer form withthe lower edge of the bottom portion closed by

fibrous cylindrical bodies in laminated form and
metal closures for the top and bottom.
The objects of ’ my invention, among other
closures or covers are applied and secured, more
particularly to the top of the container, whereby
the head cover may be ailixed firmly in place
while providing a tight sealing joint around the,
container rim; also to pro-vide an improved seal
Vor gasket construction that dispenses with the
use of ay binding agent or adhesive, and at the
same time reinforces the rim portion or margin
of the open end of the laminated fibrous con
tainer, which is of advantage when the metal
closure or cover is inserted in the open end andforced into sealing position on the slightly yield
ing fibrous body in the Zone of the gasket where 20
eiîective and uniform sealing is important.
A further object of my invention is to‘provîde a

as twisted paperrope, is secured by the continu-V
ous line stitching I3 passing through the body;
Other types of securing means may be used, kbut
I prefer the continuous line of stitching I 3 as
Ishown in Fig. 5, which enables the gasket I2 to
be slightly compressed without injuring or loos-`
ening the stitching. This annular line of stit'chf

of the body 9 as the cover £5 and lugs I6 curl out

upper side of the gasket Ii; at the same time the
lug ends 2l apply pressure beneath the` gasket I2
'which also acts to hold the lugs I6 in place. The
, stitching I3 reinforces the body margin Id below
the rim edge II, and also serves as an annular
hinge for the rim edge II when outwardly flared
and also during the subsequent curling of such
rim edge II over the gasket I2 as shown in Fig. 3.
The lug ends 2| also bear upwardly against the
under side of the gasket I2 which affords a yield

In Figs. 6-8, I have shown a modified form of
cover and attaching ring therefor. VIn this mod

and vertical annular wall I8 with channel 22
that is semi-circular in cross-sectionA as shown in
Fig.r8. The attaching ring 23 is of the usual con
struction that ñts snugly over the cover channel
22, and has lits ends formed with transversely
disposed clips 24 and 25. The clips 24 and 25
have holes bored in alinement through which the
threaded bolt 26 passes with the nut 21 screwed
