PROVISIONAL SPECIFICATION.
Improvements in Metallic Lids or Stoppers, Applicable for Cans,
Bottles, or the like.
1, JOHN WILSON of No. 2 Commercial Street, Shipley in the County of York,
Sheet-metal Worker, do hereby declare the nature of this invention to be as
follows, that is to say :-
It has for its object the production of a metallic lid or stopper applicable for
covering or filling the aperture in a can, bottle or the like, of such a nature that
when samme is placed into position to cover the aperture or opening in any of said
cans or bottles to which it may be applied, should said aperture not be perfectly
circular in form, said lid or stopper will yield so that the contour of its jointing
surfaces shall suit the contour of said aperture in this manner forming a more
perfect joint.
33
This I attain by constructing the stopper of sheet metal, preferably by the process
well known as stamping or pressing," and forming that part of said stopper
which comes in contact with the can or bottle, so that it will pass within the aperture
thereof. Around the upper part of the stopper is formed a bead or rib, while a suitable
flange is formed by the bottom edge of said stopper being turned outwardly, so that a
groove is formed around that part of the stopper which enters the aperture;
this groove being for the reception of an appropriate strip of cork as will be welĺ
understood.
From this it will be seen that by the part of the stopper that enters the aperture
being formed as above described it will yield or bulge and press its cork-covered-
surface against, so as to suit any irregularity in the contour of, the aperture which it
covers.
In order to more certainly secure the cork within its groove, without the use of
glue etc., I form the outer edge of the bead or rib above described so that it will
overlap said cork, or again instead of making said bead thus to overhang I place and
attach a supplementary cap to overlap the upper surface of the stopper and overhang
the cork as may be desired.

COMPLETE SPECIFICATION.
Improvements in Metallic Lids or Stoppers, Applicable for Cans,
Bottles, or the like.
I, JOHN WILSON of Number 2, Commercial Street, Shipley in the County of York,
Ironmonger and Sheet Metal Worker, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, that is to say:—
It has for its object the production of a metallic lid or stopper, applicable for
covering or filling the aperture in a can, bottle or the like, of such a nature and
formation that when same is placed into position to cover the circular aperture or
opening in any of said cans or bottles to which it may be applied, should said aperture
not be perfectly circular in form, said lid or stopper will yield so that the contour of
its joining surface shall suit the contour of said aperture in this manner forming a more
perfect joint.
Such being the nature and object of my said invention, in order that same may be
more readily understood 1 have hereunto appended a sheet of drawings illustrative

page_text: thereof to which by figures and letters reference is made in the following description.
Fig. 1 is a sectional view of a stopper made in accordance with this invention.
Fig. 2 is perspective view of said stopper, and fig. 3 is a similar view to fig. 1 but
shews a modification in the formation of said stopper.
The object of this invention is attained by constructing the stopper of sheet metal,
preferably by the process well known as "stamping" or "pressing," and forming the
part a of said stopper which comes in contact with the can bor bottle e shewn in
broken lines by figs. 3 and 1 respectively, so that it will pass within the aperture
thereof. Around the upper part of the stopper is formed a bead or rib d, which may
have its outer edge serrated or not as may be desired, while a suitable flange e is formed
by the bottom edge being turned outwardly, so that a groove is formed around the
part a for the reception of an appropriate strip of cork, shewn in broken lines at f, as
will be readily understood.
From this it will be seen that by the part a which enters the aperture being formed
as set forth it will yield or bulge and press its cork-covered-surface against, so as to suit
any irregularity in the contour of the aperture which it covers.
In order to securely hold the cork within its groove without the aid of glue or
other adhesive substance, I form the outer edge of the flange e above described so
that it will somewhat overlap said cork as shewn by fig. 1, or instead of making
said flange e thus to overlap I place over and attach to the inner stopper a supple-
mentary cap g (see fig. 3) the lower edge g¹ of which will overhang the cork as
desired.
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. A sheet-metal stopper formed at a, d and e substantially as herein set forth and
illustrated, for the purpose specified.
.
2. A sheet-metal stopper formed at a, d, g and g' substantially as herein set forth
and illustrated, for the purpose specified.
