IMPROVEMENTS IN CAPSULING PROTECTING, OR CLOSING THE OUTLETS OF BOTTLES
Year: 1881

page_text: LETTERS (PATENT to John Dunbar of Glasgow, in the County of Lanark,
North Britain, Machinist, for an Invention of “ IMPROVEMENTS IN CAPSULING
PROTECTING, OR CLOSING THE OUTLETS OF BOTTLES,”
PROVISIONAL SPECIFICATION left by the said John Dunbar at the Office
of the Commissioners of Patents on the 26th March 1881.
JOHN DUNBAR, of Glasgow, in the County of Lanark, North Britain, Machinist.
"IMPROVEMENTS IN CAPSULING, PROTECTING, OR CLOSING THE OUTLETS OF
BOTTLES."
.
This Invention has for its object the capsuling, protecting, or closing of the outlets
of bottles in a better manner than has hitherto been effected. When metallic
capsules are employed for the purpose in view they have to be made to contract
upon the necks of the bottles, and it is almost impossible to effect the necessary
contraction in a manner to render the capsule an air-tight fit. Besides not being
perfectly airtight a metallic capsule is destroyed when removed or opened, and
cannot be used a second time, whereas the improved capsules can be used over
again repeatedly.
The Invention consists in making the capsules of rubber, which may be vulcanised
or otherwise treated in an analogous manner. The improved capsules are moulded
and cured or otherwise formed of a shape and size to require stretching in order
to place them on the bottle necks, and by preference so as to pass over and contract
under the projecting lips or rings ordinarily formed round the ends of bottle necks.
The bottles may be closed with corks or other stoppers in the ordinary way, and
have the rubber capsule applied over all; or the rubber capsules may be used for
closing the bottles without any other stopper being employed, the capsules being,
in such cases, made of greater thickness and strength than what may be necessary
when they are to be used in conjunction with corks or other stoppers.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Dunbar in the Great Seal Patent Office on the 24th September
1881.

"IMPROVEMENTS IN CAPSULING, PROTECTING, OR CLOSING THE OUTLETS OF
BOTTLES."
My said Invention has for its object the capsuling, protecting, or closing of the
outlets of bottles in a better manner than has hitherto been effected. When
Price 4d1

page_text: metallic capsules are employed for the purpose in view, they have to be made to
contract upon the necks of the bottles, and it is almost impossible to effect the
necessary contraction in a manner to render the capsule an air-tight fit. Besides
not being perfectly air tight a metallic capsule is destroyed when removed or
opened, and cannot be used a second time, whereas my improved capsules can be
used over again repeatedly.
My Invention consists in making the capsules of rubber, which may be of the
kind known as vulcanised, or which has been treated in an analogous manner.
My improved capsules are moulded and cured, or otherwise formed of a shape and
size to require stretching in order to place them on the bottle necks, and by
preference so as to pass over and contract under the projecting lips or rings
ordinarily formed round bottle necks at or near their ends.
The bottles may be closed with corks or other stoppers in the ordinary way and
have the rubber capsule applied over all, or the rubber capsules may be used for
closing the bottles without any other stopper being employed, the capsules being
in such cases made of greater thickness and strength than what may be necessary
when they are to be used in conjunction with corks or other stoppers.
The rubber capsules may be made of various forms to suit the various forms of
bottle neck, but in order that my said Invention and the manner of performing the
same may be properly understood I hereunto append a Sheet of explanatory
Drawings on which there is represented, by way of example, a simple form of
rubber capsule suitable for the neck of an ordinary wine bottle. Figure 1 of the
said Drawings is a section of the capsule as separate and in its unstretched
condition, and Figure 2 is an elevation of a bottle having the capsule applied to
it, whilst Figure 3 is a section corresponding to the upper part of Figure 2.
Figure 3 shows the use of a cork as well as the capsule, but as herein before stated
the capsule may be used without any other stopper.
My improved capsule may have a trade mark or name or other useful or
ornamental device moulded upon it, or such marks or devices may be painted
on it, and it may be ornamented with coloring matter if desired.
Having thus particularly described my said Invention, and the manner of
performing the same, I have to state that I do not restrict myself to the precise
details herein described or delineated, but that what I believe to be novel and
original, and claim as the Invention secured to me by and in terms of the herein
before in part recited Letters Patent is,―
1. The capsuling, protecting, or closing of the outlets of bottles by means of
rubber capsules combined with corks or other stoppers, as herein before described.
2. The capsuling, protecting, or closing of the outlets of bottles by means of
rubber capsules alone, as hereinbefore described.
In witness whereof, I, the said John Dunbar, have hereunto set my hand and
seal, this Twenty-second day of September, in the year of our Lord One
Tight hand and nights ANA
