COMPLETE SPECIFICATION.
Improvements in Stoppers or Covers for Bottles, Jars, and similar
Vessels.
We, VINCENT REISER, of 12, Marlborough Road, Bradford, in the County of
York, and TOM SUTCLIFFE of 58, Copley Street, Little Horton, Bradford,
aforesaid 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 :-
This invention relates to improvements in stoppers or covers for bottles, jars and
similar vessels, and its object is to provide a cheap, light and efficient capsule
stopper or cover.
Our improvements consist in employing capsule stoppers formed of card board,
straw board, paper pulp or other suitable analogous material pressed to form after
it has been brought to a suitable plastic state and subsequently dried to harden it.
To fully describe our invention reference is made to the accompanying sheet of
drawings, forming a part of this specification, in which similar letters of reference
indicate corresponding parts in each of the figures.
Figure 1, represents an elevation of a bottle fitted with one of our capsule
stoppers.
Figure 2, represents the bottle neck with a diametrical section of the stopper
thereon and
Figure 3, a diametrical section of both the bottle neck and the stopper.
Figure 4, is a plan view of Figure 2 and Figure 5, a cross section of the stopper
on the broken line a, b Figure 3.
Figure 6, represents an elevation of the top of a jar closed by one of our
improved stoppers.
Figure 7, is a diametrical view of the stopper alone and Figure 8, a cross section
on the line y, Figure 7.
The strengthening collar A of the bottle neck B is made cylindrical in form or
by preference slightly taper, that is to say slightly smaller at the top than at the
base. The collar A has two grooves C formed in it diametrically opposite each
other. The grooves C pass vertically downwards a suitable distance and are then
deflected in a slightly inclined direction and each extend a suitable distance
towards the other groove.
The capsule stopper D has two internal projections E preferably formed solid
with it and these projections are so located that when the stopper is placed on
the bottle neck the projections pass into the grooves C down to their inclined
portions. Then by turning the stopper more or less round on the neck the
projections enter the inclined parts of the groove and the cork disc H inside the
top of the stopper is tightly pressed down on the mouth of the bottle and seals or
hermetically closes it.
A row of perforations F may be formed circumferentially around the lower part
of the stopper and an annular groove G may also be formed round the stopper to
still further reduce the strength of the walls of the stopper at that part. The
part D 2 of the stopper below the groove G is lined with gum or other suitable
cement or adhesive material so that when the capsule is in position the lower
part may be cemented to the neck. In this case to open the bottle the capsule is
twisted round with sufficient force to sever it at the perforations.

page_text: The capsule shown in Figures 6, 7 and 8 is made in the same way but it is
preferably not so deep.
For small bottles only one groove C and projection E may be employed.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
-claim is :
1. A capsule stopper for bottles formed of compressed card board, straw board,
paper pulp or other analogous material, substantially as herein shown and
.described.
2. A capsule stopper for bottles formed of compressed card board, straw board,
paper pulp or other analogous material, having a perforated lower part, substantially
as herein shown and described and for the purpose specified.
