Improvements in the Mode of Hermetically Attaching Lids to Cans
and the like.
I, WILLIAM BARKER OGDEN, of Cornwallis Street, Liverpool, in the County
of Lancaster, Tobacco Manufacturer, do hereby declare the nature of this inven-
ion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to the mode of attaching the lids to cans and the like which
have to be hermetically closed, and the object of the invention is to so attach the
lid to the can that it may be readily detached by the user without the necessity
of using a can opener or the like and without destroying the lid, so that the latter
may be used to close the can (not hermetically) while the material in the can,
tobacco for example, is being used.
In the accompanying drawings which illustrate my invention,

Improvements in the Mode of Hermetically Attaching Lids to Cans
and the like.
I, WILLIAM BARKER OGDEN, of Cornwallis Street, Liverpool, in the County
of Lancaster, Tobacco Manufacturer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :—
This invention relates to the mode of attaching the lids to cans and the like which
have to be hermetically closed, and the object of the invention is to so attach the
lid to the can that it may be readily detached by the user without the necessity
of using a can opener or the like and without destroying the lid, so that the latter
may be used to close the can (not hermetically) while the material in the can,
tobacco for example, is being used.
In the accompanying drawings which illustrate my invention,
Fig Lis an outside elevation of the upper portion of a can constructed according
to my invention,
Fig. II is a section on A. A. of Fig. IV,
Fig. III is an enlarged view of Fig. II and
Fig. 1V is a view showing the mode of making the soldered joint.
Throughout the drawings the same reference figures indicate the same parts.
The can 1 and lid 4 are of the usual construction; at the lid end the diameter of
the can is reduced so as to form a neck 2, and, preferably, a little below the neck
a circumferential corrugation 3 is formed.
The lid 4 fits over the neck and it is secured to the can by an encircling
band 5 which is connected by a soldered joint, to the lid as shown at 6, and to
the can as shown at 7 in Fig. III.
The ends of the band overlap and the overlapping portion is soldered as
shown by the crossed dotted lines in Fig. IV which indicate the soldered area;
it will be noticed that the solder on the overlapping portion of the band is
tapered and that the loose end of the band is provided with a link 8 and ring 9
to facilitate the stripping off of the band 5.
I have found that if the soldered area of the overlap of the band terminates
squarely with the band it takes great force to break the joint, and in many
cases the band will tear before the solder gives; this is quite overcome by
making the joint as shown and when the band is provided with the wire ring 9
it can be stripped with great facility and the lid is then adapted to close the
can in the ordinary way while the tobacco or other substance contained in the
can is being used.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
1. The improved mode of soldering the band 5 hereindescribed whereby a lid
hermetically secured to the can, may be detached with facility, substantially as
described and illustrated.
2. In combination, a tin 1 having a circumferential corrugation 3 and a neck of
smaller diameter, a lid 4 whose periphery is flush with the periphery of the tin
and a connecting band 5 soldered substantially as described and illustrated in the
drawings.
Dated this 6th day of July 1893.
