PROVISIONAL SPECIFICATION.
Improvements in
Means for Stopping Bottles and other
Hollow Articles.
I, FRANK BRIDGE of 9 Frith Street Soho in the County of Middlesex, Cork
Merchant do hereby declare the nature of this invention to be as follows:-
The invention has for its object. improvements in means for stopping bottles and
other hollow articles and relates to a novel combination of parts whereby an efficient
stopper is obtained and the contents of the vessel are at the same time prevented from
coming into contact with anything connected with the stopper but cork or other non-
objectionable material.
For this purpose I employ a bottle having a screw thread formed on the exterior of
the neck below which thread a flange formed to serve as a seat for an india-rubber
or other packing ring. I employ in connection with such a vessel an internally screw
threaded cap which has a cork or other packing disc cemented in the head thereof to
fit on to the upper edge or lip of the neck of the vessel.
Or the screw cap may be fitted with a short and preferably slightly conical cork
which may be solid or hollow in which latter case a descending portion of the screw
cap is cemented into the hollow cork.
By these means I obtain a double stopping arrangement as the cork fits closely the
interior or upper edge of the neck of the vessel and the india rubber or other packing
ring is tightly compressed between the lower edge of the cap and the flange on the
neck of the bottle.
COMPLETE SPECIFICATION.
Improvements in Means for Stopping Bottles and other
Hollow Articles.
I, FRANK BRIDGE, of 9 Frith Street, Soho, in the County of Middlesex, Cork
Merchant, 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 :-
The invention has for its object improvements in means for stopping bottles and
other hollow articles and relates to a novel combination of parts whereby an efficient
stopper is obtained and the contents of the vessel are at the same time prevented from
coming into contact with anything connected with the stopper but cork or other non-
objectionable material.
For this purpose I employ a bottle having a screw thread formed on the exterior of
the neck below which thread a flange is formed to serve as a seat for an india rubber
or other packing ring. I employ in connection with such a vessel an internally screw
threaded cap which has a cork or other packing disc cemented in the head thereof to
fit on to the upper edge or lip of the neck of the vessel.
Or the screw cap may be fitted with a short and preferably slightly conical cork
which may be solid or hollow in which latter case a descending portion of the screw
cap is cemented into the hollow cork.
By these means I obtain a double stopping arrangement as the cork fits closely the
interior or upper edge of the neck of the vessel and the india-rubber or other packing

page_text: carried into effect I will proceed aided by the accompanying drawings more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation with the upper part in section of part of a jar or bottle
fitted with my improved cap or stopper provided with a cork to enter the mouth of
the jar or bottle and
Figure 2 is a similar view to Figure 1. but showing the cap or stopper fitted
with a packing disc in the crown thereof to rest on the upper edge of the
bottle neck.
The exterior of the neck of the bottle or other hollow article is formed with a screw
thread a below which a flange b is formed to serve as a seat or an india rubber or
other, packing ring c. I employ in connection with such a ves el an internally screw
threaded cap d which according to the arrangement shown at Figure 1. is fitted
with a short and preferably slightly conical cork e cemented in the crown thereof. I
preferably form the interior or crown of the cap with a slight annular recess d¹ and a
downwardly projecting part d² in which case the cork is formed with a hole to fit
over the projection d²; thus by the aid of cement between the parts, the cap and
cork are firmly united.
The arrangement represented at Figure 2 is similar to that shown at Figure 1.
except that the cork e descending into the neck of the botte or other hollow article
is dispensed with and a disc e of cork or other suitable material is fitted or
cemented in the crown of the cap which in this instance is represented as perfectly
plain.
By these means I obtain a double security as the cork e fits closely the interior of
the neck of the vessel or the disc e* of cork or other material is compressed
between the upper edge of the neck of the vessel and the crown of the cap whilst
in either case the india rubber or other packing ring c is tightly compressed between
the lower edge of the cap and the flange b on the neck of the bottle or other
article.
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 combination with a screw cap of a tightly fitting cork cemented in the
head thereof and descending into the neck of the bottle or other article and a
packing ring compressed between the lower edge of the cap and a flange on the
bottle neck substantially as herein shown and described and for the purpose
stated.
2. The combination with a screw cap of a disc of cork or other material cemented
in the head thereof and compressed between the bottle neck and the head of the
cap, and a packing ring compressed between the lower edge of the cap and a flange
on the bottle neck substantially as herein shown and described and for the purpose
stated.
